Description

Technical Field

[0001] This invention relates to the field of building automation control technology, specifically a method for predicting and scheduling building air conditioning loads. Background Technology

[0002] Building air conditioning systems are crucial energy-consuming systems in public buildings, office buildings, commercial complexes, and industrial parks. Their operation is influenced by factors such as outdoor weather conditions, the heat storage characteristics of the building envelope, the intensity of human activity, the time of day for use, and the operating efficiency of the air conditioning equipment. With the development of building automation systems, energy consumption monitoring systems, and intelligent control platforms, air conditioning systems can now collect operational data from chillers, pumps, cooling towers, air handling units, fan coil units, and each air conditioning zone. This data, combined with historical cooling loads, indoor and outdoor environmental parameters, and human usage information, enables short-cycle load forecasting, providing a data foundation for air conditioning equipment start-up and shutdown, chilled water temperature setting, supply air parameter adjustment, and zonal control.

[0003] In actual operation, the cooling capacity of a building air conditioning system is not immediately and uniformly distributed to each air-conditioned zone after being output by the main unit. Instead, it passes through several stages, including cooling on the main unit side, water network distribution, heat exchange at the terminal units, and regional thermal response. Due to differences in pipe resistance, valve opening, air supply capacity, regional heat capacity, and occupant disturbance between different floors, branches, and terminal devices, the response time and intensity of the same dispatching action vary across different air-conditioned zones. Therefore, when performing load forecasting and energy-saving dispatching, in addition to predicting the cooling load, it is also necessary to consider whether the cooling capacity generated by the control action can be effectively delivered to the target air-conditioned zone within the target time.

[0004] Existing energy-saving control methods for building air conditioning typically combine predicted load, equipment energy efficiency, indoor comfort, and operating boundaries to generate scheduling schemes, which play a certain role in reducing energy consumption and improving operation and management. However, existing methods are insufficient in identifying the dynamic response relationships between the main unit side, water network side, terminal side, and regional side. They are unable to accurately characterize the arrival time, transmission intensity, attenuation degree, and cold storage capacity of different adjustable control variables of air conditioning on different air conditioning zones. This results in a lack of sufficient constraints on the actual cold load transmission characteristics in predicted load correction and candidate scheduling action selection, affecting the reliability of refined energy-saving scheduling of air conditioning systems. Summary of the Invention

[0005] Based on the shortcomings of the prior art described above, the purpose of this invention is to provide a method for predicting and scheduling building air conditioning loads to solve the aforementioned technical problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a method for predicting and scheduling building air conditioning loads, comprising: S1: Collect multi-level cooling capacity transfer data of the building air conditioning system within a preset sampling period. The multi-level cooling capacity transfer data includes main unit side output data, water network side transfer data, terminal side heat exchange data and regional side response data. S2: Determine the perturbation identification window based on regional side response data and equipment operating status; S3: Within the perturbation identification window, apply a cooling capacity marking perturbation signal to at least one adjustable control quantity of the air conditioner; S4: Based on the cold energy labeling perturbation signal, extract the incremental response of the host side, the incremental response of the water network side, the incremental response of the terminal side, and the incremental response of the regional side from the multi-level cold energy transfer data, and generate the cold energy labeling response sequence. S5: Based on the cold energy label perturbation signal and the cold energy label response sequence, the regional cold energy transfer kernel is obtained by inversion. The regional cold energy transfer kernel is used to characterize the arrival time of different air conditioning adjustable control variables on different air conditioning zones, cold energy transfer intensity, transfer attenuation degree, regional cold storage capacity and action coupling relationship. S6: Generate short-cycle cooling load forecast results based on historical cooling load data, regional environmental data, human activity data, and meteorological data. Correct the cooling load arrival capacity of the short-cycle cooling load forecast results through the regional cooling load transfer kernel to obtain the forecast load results after the transfer kernel correction. S7: Based on the regional cooling capacity transfer core, determine the effective cooling capacity contribution of candidate scheduling actions to the target air conditioning zone, and generate a table of effective contributions of candidate scheduling actions; S8: Based on the predicted load results after the transfer kernel correction and the effective contribution table of candidate scheduling actions, generate a building air conditioning energy-saving scheduling scheme.

[0007] The present invention is further configured such that S1 includes: The main unit output data includes chiller load rate, cooling capacity output, chilled water supply temperature, chilled water return temperature, and unit power. The data transmitted on the water network side includes chilled water pump frequency, chilled water flow rate, supply and return water pressure difference in the pipeline network, branch valve opening, branch flow rate, supply and return water temperature difference, and return water response time. The terminal-side heat exchange data includes the supply air temperature, return air temperature, supply air volume, coil valve opening, and fan frequency of the air conditioning unit or fan coil unit. The regional response data includes the indoor temperature, temperature change rate, and comfort setting range for each air conditioning zone.

[0008] The present invention is further configured such that S2 includes: The upper limit comfort margin and lower limit comfort margin are determined based on the distance between the indoor temperature of each air conditioning zone at the current sampling time and the upper and lower limits of the comfort setting range. When both the upper and lower comfort margins meet the corresponding preset temperature margin requirements, it is determined that the corresponding air conditioning zone has a comfort margin that can withstand minor disturbances in cooling capacity markings. Based on the indoor temperature change records during the preset historical observation period, determine the temperature fluctuation amplitude, temperature change rate and temperature change direction of the corresponding air-conditioning zone, and determine whether the corresponding air-conditioning zone meets the regional side response stability requirements. The system acquires the operating status of the air conditioning equipment associated with the corresponding air conditioning zone at the current sampling time and within a preset historical observation period, and determines that the corresponding air conditioning zone meets the equipment-side perturbation availability requirements; the operating status of the equipment includes alarm status, protection interlock status, start / stop switching status, control quantity boundary status, and control command change status; If the corresponding air conditioning zone has a comfort margin that can withstand the cold load marking perturbation, the corresponding air conditioning zone meets the regional side response stability requirements, and the corresponding air conditioning zone meets the equipment side perturbation availability requirements, then the preset time period after the current sampling time is determined as the candidate perturbation identification window. Based on the upper limit comfort margin, lower limit comfort margin, temperature change rate, temperature fluctuation amplitude, and equipment operating status, the permissible disturbance level of the candidate perturbation identification window is determined. When the permissible disturbance level reaches the preset disturbance execution level, the candidate disturbance identification window is determined as the disturbance identification window, and the window start time, window duration, corresponding air conditioning zone and permissible disturbance level of the disturbance identification window are output.

[0009] The present invention is further configured such that S3 includes: The target control quantity or a combination of target control quantities is determined from the adjustable control quantities of the air conditioner. The adjustable control quantities of the air conditioner include at least one of the following: chilled water supply temperature setpoint, chilled water pump frequency, branch valve opening, terminal coil valve opening, supply air temperature, and supply air volume. The combination of target control quantities consists of multiple adjustable control quantities of the air conditioner that have the same branch affiliation and act on the same target air conditioning zone. Before applying the cold energy marking perturbation signal, the perturbation start time, perturbation duration, perturbation amplitude, and perturbation direction of the target control quantity or combination of target control quantities are determined based on the window start time, window duration, and allowable perturbation level of the perturbation identification window. Within the perturbation identification window, cold-weighted perturbation signals are applied to the target control quantity or combination of target control quantities according to the perturbation start time, perturbation duration, perturbation amplitude, and perturbation direction; After the cold load indicator disturbance signal reaches the disturbance duration, the target control quantity or target control quantity combination will be restored to the pre-disturbance set value or the reference set value within the allowable operating range of the pre-disturbance set value. Record the disturbance object, target control quantity or combination of target control quantities, disturbance amplitude, disturbance direction, disturbance start time, disturbance end time, recovery time, corresponding air conditioning zone and corresponding branch affiliation of the cold energy marking perturbation signal; the cold energy marking perturbation signal is used to excite the cold energy transfer response of the building air conditioning system.

[0010] The present invention is further configured such that S4 includes: Using the disturbance start time of the cold energy marker perturbation signal as the time reference, a data segment located before the disturbance start time and lasting for a preset duration is extracted from the multi-level cold energy transfer data as the pre-disturbance running segment. Stability verification is performed on the operation segment before the disturbance. When the changes in the main unit output data, water network transmission data, terminal heat exchange data and regional response data in the operation segment before the disturbance do not exceed the corresponding preset benchmark fluctuation threshold, the operation segment before the disturbance is determined as the benchmark state. The response observation time window is determined based on the disturbance start time, disturbance end time, and recovery time of the cold energy labeled perturbation signal; Data within the response observation time window is extracted from the multi-level cold energy transfer data as response segments. The differences between the main unit output data, water network transfer data, terminal heat exchange data and regional response data in the response segments and the corresponding level data in the baseline state are extracted to obtain the main unit incremental response, water network incremental response, terminal incremental response and regional incremental response. According to the order of cooling capacity transfer on the main unit side, water network side, terminal side, and regional side, the incremental responses on the main unit side, water network side, terminal side, and regional side that have the same cooling capacity marker perturbation signal identifier, the same corresponding air conditioning zone, and the same branch affiliation are sequentially correlated to generate a cooling capacity marker response sequence.

[0011] The present invention is further configured such that S5 includes: The target control quantity or combination of target control quantities, disturbance amplitude and disturbance direction in the cold energy label perturbation signal record are determined as control excitations, and the incremental response on the host side, the incremental response on the water network side, the incremental response on the terminal side and the incremental response on the regional side in the cold energy label response sequence are determined as response results. According to the corresponding air conditioning zone and corresponding branch affiliation, the control excitation and response results corresponding to the same cooling capacity marker perturbation signal are matched to establish the response mapping relationship between the air conditioning adjustable control quantity and the air conditioning zone. Based on the response occurrence time, peak response amplitude, response duration, and response decay process of the incremental response on the regional side in the cold energy label response sequence, as well as the disturbance start time and disturbance amplitude of the corresponding cold energy label perturbation signal, the arrival time of the action of the target control quantity on the corresponding air conditioning zone, the intensity of cold energy transfer, and the regional cold storage capacity are determined. Based on the relationship between the incremental response amplitudes of the main unit side, the water network side, the terminal side, and the regional side in the sequence of cooling capacity transfer, the degree of transfer attenuation of the target control quantity to the corresponding air conditioning zone is determined. When multiple adjustable air conditioning control quantities act on the same air conditioning zone under the same branch affiliation, the action coupling relationship between the multiple adjustable air conditioning control quantities is determined based on the deviation relationship between the area-side incremental response corresponding to a single adjustable air conditioning control quantity and the area-side incremental response corresponding to the combination of target control quantities. The arrival time of the action, the intensity of cold transfer, the degree of transfer attenuation, the regional cold storage capacity and the action coupling relationship are associated and stored according to the air conditioning zone, branch network affiliation and air conditioning adjustable control quantity to form the regional cold transfer core of the corresponding air conditioning zone.

[0012] The present invention is further configured such that S6 includes: Obtain the short-cycle cooling load forecast results for each air conditioning zone, and call the regional cooling capacity transfer core of the corresponding air conditioning zone. The short-cycle cooling load forecast results include the predicted cooling load demand and the predicted load occurrence period. Based on the matching relationship between the predicted load occurrence period and the action arrival time in the corresponding area's cooling capacity transfer core, the cooling capacity response time status of the corresponding air conditioning zone is determined. Based on the matching relationship between the predicted cooling load demand and the cooling intensity, attenuation degree and cold storage capacity of the corresponding area's cooling core, the cooling capacity of the corresponding air conditioning zone is determined to be in a suitable state. Based on the cooling capacity response time status and the cooling capacity reaching the adaptation status, the corresponding air conditioning zones are marked as easily adjustable load areas or load transfer restricted areas. When the predicted cooling load demand of the corresponding air conditioning zone is lower than the preset load threshold, and the indoor temperature of the air conditioning zone deviates from the comfort setting range within a preset duration, and the cooling transfer intensity in the corresponding area's cooling transfer core is lower than the preset transfer intensity threshold or the transfer attenuation degree is higher than the preset attenuation threshold, the air conditioning zone is marked as an area with insufficient cooling capacity. Based on the easily adjustable load areas, the load areas with limited transmission, and the areas with insufficient cooling capacity, the short-cycle cooling load forecast results for each air conditioning zone are augmented with cooling capacity arrival capacity markers, adjustment priority markers, and cooling mode markers to generate the predicted load results after transmission core correction.

[0013] The present invention is further configured such that S7 includes: For each candidate scheduling action in the preset candidate scheduling action set, the regional cooling transfer core corresponding to the target air conditioning zone is called to determine the action arrival time, cooling transfer intensity and transfer attenuation degree when the candidate scheduling action is applied to the target air conditioning zone. Based on the arrival time of the action, the intensity of cold energy transfer, and the degree of transfer attenuation, determine the effective cold energy contribution of the candidate scheduling action in the target air conditioning zone; based on the difference in equipment energy consumption before and after the execution of the candidate scheduling action, determine the change in action energy consumption corresponding to the candidate scheduling action; based on whether the equipment control quantity after the execution of the candidate scheduling action exceeds the equipment operating boundary, determine the equipment operating boundary satisfaction status; based on whether the expected indoor temperature of the target air conditioning zone after the execution of the candidate scheduling action exceeds the comfort setting range, determine the comfort risk status. The candidate scheduling actions, target air conditioning zones, action arrival time, effective cooling capacity contribution, action energy consumption changes, equipment operating boundary satisfaction status, and comfort risk status are correlated to generate an effective contribution table for candidate scheduling actions.

[0014] The present invention is further configured such that S8 includes: The scheduling order of each air conditioning zone is determined according to the adjustment priority mark; according to the scheduling order, for each air conditioning zone, candidate scheduling actions that meet the equipment operation boundary and have no comfort risk are selected from the effective contribution table of candidate scheduling actions as safety candidate actions. When the effective cooling capacity contribution of a single safety candidate action meets the predicted cooling load demand of the air conditioning zone, the corresponding safety candidate action is determined as an available scheduling action; when the effective cooling capacity contribution of multiple safety candidate actions meets the predicted cooling load demand of the air conditioning zone, the safety candidate action with the lower energy consumption change is selected as an available scheduling action; when the effective cooling capacity contribution of a single safety candidate action is insufficient to meet the predicted cooling load demand, multiple safety candidate actions are selected to form an available scheduling action combination. The control command issuance time is determined based on the arrival time of the selected available scheduling actions and the predicted load occurrence period of the corresponding air conditioning zone; Based on the selected available scheduling actions, control command issuance time, control command duration, and target air conditioning zone, a building air conditioning energy-saving scheduling scheme is generated.

[0015] The present invention is further configured such that the duration of the control command is determined based on the predicted load occurrence period of the corresponding air conditioning zone and the action type of the selected available scheduling action.

[0016] This invention provides a method for predicting and scheduling building air conditioning loads. The method comprises: S1: collecting multi-level cooling load transfer data of the building air conditioning system within a preset sampling period, including main unit output data, water network transfer data, terminal heat exchange data, and regional response data; S2: determining a perturbation identification window based on the regional response data and equipment operating status; S3: applying a cooling load labeling perturbation signal to at least one adjustable control variable of the air conditioning system within the perturbation identification window; S4: extracting the main unit incremental response, water network incremental response, terminal incremental response, and regional incremental response from the multi-level cooling load transfer data based on the cooling load labeling perturbation signal, generating a cooling load labeling response sequence; and S5: retrieving the regional cooling load based on the cooling load labeling perturbation signal and the cooling load labeling response sequence. The transfer kernel, or regional cooling capacity transfer kernel, is used to characterize the arrival time, cooling capacity transfer intensity, transfer attenuation degree, regional cooling storage capacity, and action coupling relationship of different adjustable control variables for different air conditioning zones; S6: Based on historical cooling load data, regional environmental data, personnel activity data, and meteorological data, short-cycle cooling load forecast results are generated. The cooling capacity arrival capacity is corrected for the short-cycle cooling load forecast results using the regional cooling capacity transfer kernel, resulting in the predicted load result after kernel correction; S7: Based on the regional cooling capacity transfer kernel, the effective cooling capacity contribution of candidate scheduling actions to the target air conditioning zone is determined, and a table of effective contributions of candidate scheduling actions is generated; S8: Based on the predicted load result corrected by the transfer kernel and the table of effective contributions of candidate scheduling actions, a building air conditioning energy-saving scheduling scheme is generated, resulting in the following beneficial effects: The perturbation identification window is determined based on the regional response data and equipment operating status. The cooling capacity marking perturbation signal is applied only when the air-conditioning zone has a comfort margin, the regional response is stable, and the equipment meets the perturbation availability conditions. The perturbation amplitude, duration, and direction of the cooling capacity marking perturbation signal are limited by the perturbation level, so that the perturbation process is kept within a small, short-term, and recoverable control range. Using the cold energy labeled perturbation signal as the control excitation, the incremental responses from the host side, water network side, terminal side, and regional side are extracted to generate a cold energy labeled response sequence. Based on the cold energy labeled response sequence, a regional cold energy transfer kernel is formed. The regional cold energy transfer kernel can characterize the action arrival time, cold energy transfer intensity, transfer attenuation degree, regional cold storage capacity, and action coupling relationship when different adjustable control quantities of air conditioning are applied to different air conditioning zones. It can provide a structured expression of the actual cold energy response formed by different control actions in the target air conditioning zone, reduce the identification bias caused by simply equating host load increase, water pump adjustment, and terminal adjustment with cooling action, and improve the identification accuracy of cold energy arrival difference, response delay, and transfer attenuation. Based on the regional cooling capacity transfer core, the effective cooling capacity contribution of candidate scheduling actions to the target air conditioning zone is determined. Combined with the changes in action energy consumption, the equipment operating boundary satisfaction status, and the comfort risk status, an effective contribution table of candidate scheduling actions is generated. This allows the actual effect of different candidate scheduling actions to be evaluated before the building air conditioning energy-saving scheduling scheme is generated. Priority can be given to scheduling actions that can generate effective cooling capacity contribution to the target air conditioning zone, have low action energy consumption changes, and meet the comfort and equipment operating boundary requirements. This reduces ineffective cooling, increased energy consumption, and equipment operation fluctuations caused by directly increasing the load of chiller units or frequently switching unit combinations.

[0022] A method for predicting and scheduling building air conditioning loads, such as Figure 1 As shown, it includes: S1: Collect multi-level cooling capacity transfer data of the building air conditioning system within a preset sampling period. The multi-level cooling capacity transfer data includes main unit side output data, water network side transfer data, terminal side heat exchange data and regional side response data. S2: Determine the perturbation identification window based on regional side response data and equipment operating status; S3: Within the perturbation identification window, apply a cooling capacity marking perturbation signal to at least one adjustable control quantity of the air conditioner; S4: Based on the cold energy labeling perturbation signal, extract the incremental response of the host side, the incremental response of the water network side, the incremental response of the terminal side, and the incremental response of the regional side from the multi-level cold energy transfer data, and generate the cold energy labeling response sequence. S5: Based on the cold energy label perturbation signal and the cold energy label response sequence, the regional cold energy transfer kernel is obtained by inversion. The regional cold energy transfer kernel is used to characterize the arrival time of different air conditioning adjustable control variables on different air conditioning zones, cold energy transfer intensity, transfer attenuation degree, regional cold storage capacity and action coupling relationship. S6: Generate short-cycle cooling load forecast results based on historical cooling load data, regional environmental data, human activity data, and meteorological data. Correct the cooling load arrival capacity of the short-cycle cooling load forecast results through the regional cooling load transfer kernel to obtain the forecast load results after the transfer kernel correction. S7: Based on the regional cooling capacity transfer core, determine the effective cooling capacity contribution of candidate scheduling actions to the target air conditioning zone, and generate a table of effective contributions of candidate scheduling actions; S8: Based on the predicted load results after the transfer kernel correction and the effective contribution table of candidate scheduling actions, generate a building air conditioning energy-saving scheduling scheme.

[0023] The present invention is further configured such that S1 includes: The main unit output data includes chiller load rate, cooling capacity output, chilled water supply temperature, chilled water return temperature, and unit power. The data transmitted on the water network side includes chilled water pump frequency, chilled water flow rate, supply and return water pressure difference in the pipeline network, branch valve opening, branch flow rate, supply and return water temperature difference, and return water response time. The terminal-side heat exchange data includes the supply air temperature, return air temperature, supply air volume, coil valve opening, and fan frequency of the air conditioning unit or fan coil unit. The regional response data includes the indoor temperature, temperature change rate, and comfort setting range of each air conditioning zone. Specifically, the data acquisition of the building air conditioning system is collaboratively completed by the building automation platform, chiller group control platform, water pump control cabinet, cooling tower control cabinet, terminal air conditioning unit controller, fan coil unit controller, and temperature sensors in each air conditioning zone. The system reads the main unit output data, water network transmission data, terminal heat exchange data, and regional response data according to a preset sampling period. Each piece of collected data is appended with the acquisition time, equipment number, branch number, and the corresponding air conditioning zone number, ensuring that the main unit output data corresponds to the chiller unit generating cooling capacity, and that the water network transmission data corresponds to the chilled water main, branches, and valves that deliver cooling capacity. End-side heat exchange data can be mapped to the air conditioning unit or fan coil unit performing air-side heat exchange, enabling zone-side response data to be mapped to the air-conditioning zone receiving cooling load. Furthermore, according to the transmission path of cooling load—from chiller output, through the chilled water network, through terminal equipment heat exchange, and finally to the room area—data from different sources is path-bound and time-correlated. This organizes the main unit-side, water network-side, terminal-side, and zone-side data into a continuous data chain reflecting the sequence of cooling load transmission, equipment affiliation, branch affiliation, and zone response. Main unit-side output data characterizes the cooling load generation status of the chiller unit within the current sampling period. The chiller unit load rate, read by the unit controller, characterizes the current operating load of the chiller unit. The chiller's output cooling capacity is measured relative to its rated cooling capacity. The output is obtained from the unit's built-in cooling capacity metering module or calculated based on the chilled water flow rate and the temperature difference between the chilled water supply and return temperatures. This represents the actual cooling capacity released by the chiller to the chilled water side during the current sampling period. The chilled water supply temperature represents the low-temperature water state output from the chiller to the chilled water network. The chilled water return temperature represents the water temperature state when the chilled water returns to the chiller after being transported through the water network and undergoing terminal heat exchange. The unit power represents the energy consumption level of the chiller under corresponding cooling capacity output conditions. By synchronously collecting and time-stamping the chiller's load rate, cooling capacity output, chilled water supply temperature, chilled water return temperature, and unit power, the system can... This data is sufficient to record the cooling output status of the main unit during the current sampling period, providing a data basis for subsequent identification of whether changes in cooling capacity on the main unit are transmitted to the terminal units along the water network and whether a temperature response is generated in the area. The data transmitted from the water network side is used to characterize the effectiveness of the cooling capacity generated on the main unit being transmitted to the corresponding branches, terminal equipment, and air conditioning zones through the chilled water network. The chilled water pump frequency is read by the pump frequency converter to characterize the pump's delivery drive status during the current sampling period and serves as the basis for judging changes in the water network's delivery capacity. The chilled water flow rate is obtained from the main pipe flow meter or branch flow meter to characterize the actual flow scale of chilled water in the main pipe or target branch per unit time and serves as the basis for judging whether the cooling capacity has a delivery carrier.The supply and return water pressure difference is collected by pressure sensors in the supply and return pipes. This data characterizes the transport power generated by the pressure difference between the two ends of the chilled water network and is used to determine if there is insufficient transport power or abnormal hydraulic distribution in the network. The branch valve opening is collected by the branch electric valve controller. This data characterizes the allowable flow of chilled water in the target branch and is used to determine if the branch has the necessary channels to receive cooling capacity from the main unit. The branch flow rate characterizes the actual chilled water flow scale received by the target air conditioning zone or target terminal equipment group and is used to determine if cooling capacity enters the corresponding branch. The chilled water supply and return water temperature difference characterizes the temperature change of the chilled water after transport through the water network and terminal heat exchange, and is used to determine if cooling capacity is effectively consumed during the transfer process. The return water response time... This is used to characterize the time interval during which the corresponding branch return water temperature or total return water temperature undergoes a continuous and identifiable change after control changes occur in the chilled water supply temperature, chilled water pump frequency, branch valve opening, or terminal valve opening. The return water response time is determined through a continuous sampling process of the corresponding branch return water temperature or total return water temperature. When any adjustable control quantity among the chilled water supply temperature setpoint, chilled water pump frequency, branch valve opening, or terminal valve opening undergoes a cold energy perturbation change, the moment of occurrence of this cold energy perturbation change is used as the response timing start point. After the response timing start point, the corresponding branch return water temperature or total return water temperature is continuously acquired according to a preset sampling period, and the acquired return water temperature sequence is compared with the return water temperature reference state under the steady state before the perturbation. The return water temperature sequence is compared with the reference return water temperature state; when the return water temperature sequence shows a continuous change with the same direction, amplitude reaching the preset identifiable change requirement, and duration reaching the preset observation requirement, the moment when the continuous change first reaches the preset identifiable change requirement is determined as the return water response occurrence moment; the time interval between the response timing start point and the return water response occurrence moment is determined as the return water response time; the return water response time is used to characterize the time required for the cold energy marker perturbation signal to be transmitted through the chilled water pipe network and form an observable feedback on the return water side, thereby providing time characteristics for subsequent judgment on whether the cold energy delivery on the water network side is effective, whether there is a lag in cold energy delivery, and the arrival time and degree of delivery attenuation in the regional cold energy delivery core; the end-side heat exchange data is used to characterize the change caused by the cold energy transfer. The actual state of the conversion of cooling capacity from the water network side to the air cooling capacity in the air handling unit or fan coil unit is described. Specifically, the supply air temperature is collected by the supply air temperature sensor of the air handling unit or fan coil unit, representing the temperature level of the air output from the terminal equipment to the corresponding air conditioning zone; the return air temperature is collected by the return air inlet temperature sensor, representing the temperature level of the air in the corresponding air conditioning zone before entering the terminal equipment; the supply air volume is obtained from the air volume sensor, valve feedback value, or fan operating parameters, representing the scale of air delivery from the terminal equipment to the corresponding air conditioning zone; the coil valve opening is obtained from feedback from the terminal electric valve, representing the flow rate of chilled water into the terminal coil; and the fan frequency is read from the terminal fan inverter or terminal controller, representing the air-side delivery capacity of the terminal equipment.By performing correlation analysis on supply air temperature, return air temperature, supply air volume, coil valve opening, and fan frequency, it can be determined whether the cooling capacity on the water network side forms an effective air-side cooling effect at the terminal heat exchanger. Zone-side response data is used to characterize the environmental response results within the air conditioning zone after the cooling capacity is output from the main unit, transferred through the water network side, and exchanged at the terminal side. The indoor temperature of each air conditioning zone is collected by temperature sensors arranged in the corresponding area. When multiple temperature sensors are installed in the same air conditioning zone, abnormal sensor data is first eliminated based on sensor communication status, sampling continuity, and temperature jumps between adjacent sampling times, and then combined with the data from each temperature zone. The sensor's placement, coverage area, distance from the activity area, and the usable space of the area determine the representative temperature of the region. The rate of temperature change is obtained from the continuous sampling time of the representative temperature change process, used to characterize the heating trend, cooling trend, or temperature maintenance trend of the air-conditioned zone under the current cooling conditions. The comfort setting range is determined based on the building operation strategy, the functional attributes of the air-conditioned zone, the time of day for zone use, and user setting requirements. Different functional zones are configured with corresponding upper and lower comfort temperature limits. By correlating the representative temperature, the rate of temperature change, and the comfort setting range, it is possible to determine... Whether changes in the output of the main unit, the water network transmission, and the heat exchange at the terminal side ultimately translate into effective temperature improvement within the target air conditioning zone; uniform time processing and abnormal sampling removal are performed on the main unit output data, water network transmission data, terminal heat exchange data, and regional response data. Specifically: the sampling interval corresponding to the preset sampling period is used as the uniform sampling interval, and a baseline sampling time sequence is formed using the uniform sampling interval; the main unit output data, water network transmission data, terminal heat exchange data, and regional response data are mapped to the baseline sampling time sequence according to their acquisition time; for data with a sampling frequency higher than the uniform sampling interval, the data with the closest acquisition time to the baseline sampling time is selected in the time neighborhood corresponding to each baseline sampling time as the data for that baseline sampling time; for data with a sampling frequency lower than the uniform sampling interval, while maintaining the original acquisition order and original time stamp, it is marked to the adjacent baseline sampling time or adjacent baseline sampling period, and the time offset between it and the baseline sampling time is retained; for data items lacking corresponding sampling values ​​at the same baseline sampling time, they are marked as data to be supplemented or unusable data, and whether to participate in processing is selected according to data integrity requirements during subsequent cooling capacity marking response extraction.After completing time mapping, anomaly sampling identification is performed on data at each level. If chilled water supply temperature, chilled water return temperature, branch flow rate, network supply and return water pressure difference, supply air temperature, return air temperature, or indoor temperature shows a sudden change between adjacent reference sampling times that exceeds the corresponding equipment's adjustment capacity or sensor range variation characteristics; or if a branch valve is closed but the branch flow rate continues to show an effective high flow rate; or if the chilled water pump frequency does not change accordingly but the chilled water flow rate shows a jump that does not conform to the network operating status; or if the indoor temperature shows a sudden and significant change that does not conform to the regional thermal inertia within a short period of time; or if the relevant equipment is in an alarm state, protection interlock state, communication interruption state, or sensor offline state, then the data at the corresponding reference sampling time is marked as an abnormal sampling point. Abnormal sampling points do not participate in subsequent cold energy marking response extraction, incremental response generation, and regional cold energy transfer kernel inversion. After unifying the sampling interval, the data at each level is reorganized according to the cold energy transfer path, with the chiller unit as the cold energy generation node, and the chiller unit load rate, cold energy output, chilled water supply temperature, chilled water return temperature, and... The unit power is included in the main unit's output data; using the chilled water main and each chilled water branch as cooling capacity delivery nodes, the chilled water pump frequency, chilled water flow rate, supply and return water pressure difference in the pipe network, branch valve opening, branch flow rate, chilled water supply and return water temperature difference, and return water response time are included in the water network side's transmission data; using air conditioning units or fan coil units as cooling capacity heat exchange nodes, the supply air temperature, return air temperature, supply air volume, coil valve opening, and fan frequency are included in the terminal side's heat exchange data; using air conditioning zones as environmental response nodes after cooling capacity action, the indoor temperature, temperature change rate, and comfort level are included in the data. Appropriately define the scope for including regional response data; establish a hierarchical correspondence between main unit output data, water network transmission data, terminal heat exchange data, and regional response data based on unit number, branch number, terminal equipment number, and air conditioning zone number; group data with the same cold energy transfer path at the same sampling time or continuous sampling period into a correlation chain, so that this correlation chain can characterize the continuous transfer process of cold energy generated by the chiller unit, transported through the chilled water network, completed heat exchange at the terminal equipment, and ultimately causing the temperature response of the air conditioning zone.

[0024] The present invention is further configured such that S2 includes: The upper limit comfort margin and lower limit comfort margin are determined based on the distance between the indoor temperature of each air conditioning zone at the current sampling time and the upper and lower limits of the comfort setting range. When both the upper and lower comfort margins meet the corresponding preset temperature margin requirements, it is determined that the corresponding air conditioning zone has a comfort margin that can withstand minor disturbances in cooling capacity markings. Based on the indoor temperature change records during the preset historical observation period, determine the temperature fluctuation amplitude, temperature change rate and temperature change direction of the corresponding air-conditioning zone, and determine whether the corresponding air-conditioning zone meets the regional side response stability requirements. The system acquires the operating status of the air conditioning equipment associated with the corresponding air conditioning zone at the current sampling time and within a preset historical observation period, and determines that the corresponding air conditioning zone meets the equipment-side perturbation availability requirements; the operating status of the equipment includes alarm status, protection interlock status, start / stop switching status, control quantity boundary status, and control command change status; If the corresponding air conditioning zone has a comfort margin that can withstand the cold load marking perturbation, the corresponding air conditioning zone meets the regional side response stability requirements, and the corresponding air conditioning zone meets the equipment side perturbation availability requirements, then the preset time period after the current sampling time is determined as the candidate perturbation identification window. Based on the upper limit comfort margin, lower limit comfort margin, temperature change rate, temperature fluctuation amplitude, and equipment operating status, the permissible disturbance level of the candidate perturbation identification window is determined. When the permissible disturbance level reaches the preset disturbance execution level, the candidate disturbance identification window is determined as the disturbance identification window, and the window start time, window duration, corresponding air conditioning zone, and permissible disturbance level of the disturbance identification window are output. Specifically, the disturbance identification window is used to determine whether the current operating conditions meet the application requirements of the cooling capacity marking disturbance signal. The disturbance identification window is determined when the current indoor temperature of the target air conditioning zone has a preset safety margin between the current temperature and the comfort setting range, the temperature change process of the target air conditioning zone is stable during the preset historical observation period, the air conditioning equipment associated with the target air conditioning zone is not in an alarm state, protection interlock state, start / stop switching state, or control quantity boundary limited state, or control command change limited state. By setting a perturbation recognition window, the system can exclude periods when the indoor temperature of a zone is close to the comfort boundary, when the indoor temperature of a zone rises or falls rapidly, when the associated air conditioning equipment is malfunctioning, when the associated air conditioning equipment is subject to protection control restrictions, and when the associated air conditioning equipment lacks adjustment margin before applying the cooling capacity marking perturbation signal. This ensures that the cooling capacity marking perturbation signal is applied only when there is a safety margin in zone comfort, the zone-side response is identifiable, and the equipment-side is executable, thereby reducing the impact of the cooling capacity marking perturbation signal on indoor comfort and minimizing its interference with the normal protection control process and routine operation adjustment process of the air conditioning equipment. It also acquires the indoor temperature, temperature change rate, and comfort setting range of each air conditioning zone at the current sampling time; when a certain... When multiple temperature sensors are installed in an air-conditioned zone, the validity of the collected values ​​from each temperature sensor is screened. Sensor data with communication abnormalities, sudden jumps in collected values, prolonged periods of unchanged collected values, or deviations from other temperature collected values ​​in the same air-conditioned zone exceeding a preset allowable range are marked as abnormal data and removed when determining the current indoor temperature. For air-conditioned zones with large areas such as open-plan offices, meeting areas, corridors, and public halls, a representative indoor temperature that can characterize the overall thermal state of the air-conditioned zone is determined based on the location and coverage of the effective temperature sensors and the distribution of personnel activity in the corresponding area. For independent rooms or smaller air-conditioned zones, the main temperature sensor in the air-conditioned zone is used to determine the representative indoor temperature. The valid collected value is determined as the current indoor temperature; based on the indoor temperature change process of multiple consecutive sampling points before the current sampling time, the temperature change rate of the air conditioning zone is determined, and based on the temperature change rate, it is determined whether the air conditioning zone is in a heating state, cooling state, stable state, or fluctuating state; the comfort setting range of the air conditioning zone is determined according to the building operation strategy, the functional attributes of the air conditioning zone, the area usage time, and user setting requirements, so that the subsequent determination of the perturbation identification window can simultaneously adapt to the comfort boundary, space usage attributes, and temperature response characteristics of different air conditioning zones; when determining the upper and lower comfort margins, the current indoor temperature is compared with the upper and lower limits of the comfort setting range, respectively;The temperature distance between the upper limit of the comfort setting range and the current indoor temperature is defined as the upper comfort margin, representing the safe space for the air conditioning zone to move away from the upper comfort boundary in the direction of increasing indoor temperature. The temperature distance between the current indoor temperature and the lower limit of the comfort setting range is defined as the lower comfort margin, representing the safe space for the air conditioning zone to move away from the lower comfort boundary in the direction of decreasing indoor temperature. A larger upper comfort margin indicates that the air conditioning zone is less likely to exceed the upper limit of the comfort setting range during a short-term heat recovery or disturbance recovery process. A larger lower comfort margin indicates that the air conditioning zone is less likely to fall below the lower limit of the comfort setting range during a short-term cooling or cooling capacity increase process. (Due to the cooling capacity marking...) The perturbation signal may cause a short-term drop in indoor temperature by increasing cooling, lowering supply air temperature, or increasing supply air volume, or it may cause a short-term rise in indoor temperature during the control recovery process after the perturbation ends. Therefore, it is necessary to simultaneously verify the upper and lower comfort margins. When both the upper and lower comfort margins meet the corresponding preset temperature margin requirements, the air conditioning zone is determined to have a comfort margin that can withstand the cooling capacity-marked perturbation. When either the upper or lower comfort margin does not meet the corresponding preset temperature margin requirements, the current indoor temperature of the air conditioning zone is determined to be too close to the comfort boundary and does not meet the conditions for active perturbation application. When judging the stability of the zone-side response, the indoor temperature change record within the preset historical observation period is obtained. The preset historical observation period is a time interval formed by continuous data collection prior to the current sampling time. For air-conditioned zones with strong heat storage capacity in walls, furniture, and building envelopes, and relatively slow indoor temperature changes, the preset historical observation period is set to a longer time interval that covers their slow temperature change process, so as to fully reflect the natural temperature evolution trend of the air-conditioned zone before the application of the cooling capacity labeling perturbation signal. For air-conditioned zones with frequent personnel entry and exit, rapid changes in internal heat sources, or sensitive indoor temperature response, the preset historical observation period is set to a shorter time interval that covers multiple continuous temperature sampling points and reflects the recent temperature change direction, so as to avoid excessively long historical data weakening the representativeness of the current temperature state. The system performs continuity checks, fluctuation amplitude identification, change rate identification, and change direction identification on indoor temperature change records within a preset historical observation period. This determines whether the air-conditioning zone is in a stable state with gentle temperature changes, controllable fluctuation amplitude, and no continuous approach to the comfort boundary before the application of the cooling capacity marking perturbation signal. This provides a regional response basis for determining whether to determine the perturbation identification window. Temperature fluctuation amplitude is used to characterize the degree to which the indoor temperature fluctuates around the current operating state within the preset historical observation period. When determining the temperature fluctuation amplitude, the system first extracts the continuous indoor temperature sampling values ​​of the corresponding air-conditioning zone within the preset historical observation period and removes sampling values ​​with communication anomalies, sudden jumps in readings, or significant deviations from adjacent sampling trends.The highest and lowest indoor temperatures are determined from the remaining valid indoor temperature samples. The difference between the highest and lowest indoor temperatures is taken as the temperature fluctuation amplitude of the air-conditioned zone within a preset historical observation period. A large temperature fluctuation amplitude indicates that there was already a significant temperature disturbance in the air-conditioned zone before the application of the cooling capacity marking perturbation signal. The temperature fluctuation amplitude is compared with a preset temperature fluctuation threshold. If the temperature fluctuation amplitude does not exceed the preset temperature fluctuation threshold, the indoor temperature fluctuation of the air-conditioned zone is determined to be within an acceptable range, and the perturbation identification window judgment is allowed to continue. If the temperature fluctuation amplitude exceeds the preset temperature fluctuation threshold, the air-conditioned zone is determined not to meet the active perturbation identification conditions at the current stage, and the perturbation identification is prohibited. The corresponding time period for this air conditioning zone is designated as the perturbation identification window; the rate of temperature change is used to characterize how quickly the indoor temperature changes within a preset historical observation period. In specific processing, continuous indoor temperature sampling values ​​within the preset historical observation period are read in chronological order, and the short-term temperature change rate within the corresponding sampling interval is determined based on the increase or decrease in indoor temperature between adjacent sampling points. Then, the short-term temperature change rates within multiple consecutive sampling intervals are sequentially judged to determine the overall temperature change rate within the preset historical observation period. When the short-term temperature change rates within multiple consecutive sampling intervals all show an increase in temperature and the magnitude of change continues to increase, it indicates that the air conditioning zone is in a continuous heating process; when multiple consecutive sampling intervals show a continuous increase in temperature, it indicates that the air conditioning zone is in a continuous heating process. When the short-term temperature change rate within the zone consistently shows a cooling trend with a continuously increasing amplitude, it indicates that the air-conditioned zone is undergoing a continuous cooling process. When the overall temperature change rate exceeds a preset temperature change rate threshold, it indicates that the indoor temperature of the air-conditioned zone is in a state of rapid change. Under this state, applying a cooling capacity label perturbation signal can easily cause the zone-side response to be superimposed on the original heating or cooling process, making it difficult to accurately distinguish whether the incremental zone-side response originates from the cooling capacity label perturbation signal or from the original temperature change process. When the overall temperature change rate does not exceed the preset temperature change rate threshold, it indicates that the indoor temperature change process of the air-conditioned zone is relatively gentle, and the original temperature change does not interfere with the cooling capacity label response sequence. The temperature is relatively small and has the conditions to continue to perform perturbation identification window judgment; the continuous state of temperature change direction is used to determine whether the indoor temperature has a trend of continuously approaching the boundary of the comfort setting range. In specific processing, based on the indoor temperature change direction of continuous sampling points within a preset historical observation period, the rising, falling, or maintaining state of indoor temperature between adjacent sampling points is identified; when the indoor temperature shows an increase in multiple consecutive sampling cycles, and the direction of increase points to the upper limit of the comfort setting range, it is determined that the air conditioning zone has a trend of approaching the overheat boundary; when the indoor temperature shows a decrease in multiple consecutive sampling cycles, and the direction of decrease points to the lower limit of the comfort setting range, it is determined that the air conditioning zone has a trend of approaching the overcool boundary.If the indoor temperature continuously approaches the upper or lower limit of the comfort setting range, even if the current indoor temperature is still within the comfort setting range, it indicates that the temperature state of the air conditioning zone is not yet stable. Applying a cooling capacity perturbation signal can easily cause the zone temperature to approach the comfort boundary further or cause the perturbation response to overlap with the original temperature change trend. Therefore, only when the indoor temperature does not continuously rise towards the upper limit of the comfort setting range and does not continuously decrease towards the lower limit of the comfort setting range within the preset historical observation period is the air conditioning zone deemed to meet the zone-side response stability requirements. When determining the availability of equipment-side perturbations, the air conditioning zone with a cooling capacity supply relationship with the corresponding air conditioning zone is obtained. The system monitors the operating status of the equipment at the current sampling time and within a preset historical observation period. The air conditioning equipment with a cooling supply relationship includes chillers, chilled water pumps, corresponding chilled water branch valves, air conditioning units, fan coil units, and other terminal equipment that provide cooling to the air conditioning zone. A pre-established association between chillers, chilled water branches, terminal equipment, and air conditioning zones is created based on the unit number, branch number, terminal equipment number, and air conditioning zone number. When multiple terminal equipment jointly provide cooling for an air conditioning zone, the operating status of each terminal equipment is simultaneously acquired, and the operating status of each terminal equipment is included in the equipment-side perturbation availability judgment range for that air conditioning zone. When an air conditioning zone is associated with a specific chilled water branch, the operating status of the chilled water branch valves, branch flow, and related chilled water pumps is simultaneously acquired, and this operating status is used as the basis for determining whether the cooling capacity marking perturbation signal can be effectively executed along the corresponding branch. Through the acquisition and association of the above-mentioned equipment operating status, it can be determined whether the cooling capacity generating equipment, cooling capacity conveying equipment, and terminal heat exchange equipment corresponding to the target air conditioning zone are in operating conditions that can safely and stably accept small, short-term changes in control quantities. The alarm status in the equipment operating status is used to characterize whether there are fault prompts, abnormal protection prompts, or operating alarm prompts for the associated air conditioning equipment. When associated with the corresponding air conditioning zone... When chiller units, chilled water pumps, branch valves, air conditioning units, or fan coil units are in alarm status, it indicates that the operating conditions of the relevant equipment have deviated from the normal control range, and the corresponding time period of the air conditioning zone is not considered as a disturbance identification window; the protection interlock status is used to characterize whether the associated air conditioning equipment is in a prohibited adjustment state due to safety protection, temperature protection, pressure protection, water flow protection, or operating condition limitations; when the associated air conditioning equipment is in protection interlock status, it indicates that the control quantity of the equipment is not suitable to be actively changed, and the corresponding time period of the air conditioning zone does not meet the equipment-side disturbance availability requirements; the start-stop switching status is used to characterize whether the associated air conditioning equipment is in the process of starting, stopping, loading, unloading, or switching operating modes;When the associated air conditioning equipment is in a start-stop switching state, it indicates that the equipment's operating parameters are transitioning from one operating state to another. The main unit's output data, water network data, terminal heat exchange data, or zone response data may be affected by the start-stop switching process. Applying a cooling capacity marking perturbation signal at this time will cause the response changes caused by the equipment's own state switching to be mixed into the subsequent cooling capacity marking response sequence, making it difficult to distinguish the source of the response corresponding to the cooling capacity marking perturbation signal. Therefore, the corresponding time period for this air conditioning zone does not meet the equipment-side perturbation availability requirement. The control quantity boundary state is used to characterize the positional relationship between the adjustable control quantity of the air conditioning equipment associated with the target air conditioning zone and the allowable adjustment range. When the chilled water pump frequency has reached the upper limit of the allowable frequency or the allowable... When the frequency lower limit, branch valve opening is close to fully open or fully closed, air supply volume has reached the fan's allowable air supply range boundary, and chilled water supply temperature setpoint is close to the allowable setpoint boundary, it indicates that the corresponding adjustable control quantity lacks adjustable space to continue changing along the preset disturbance direction. In this state, if the corresponding adjustable control quantity continues to be used as the target of the cooling capacity marking perturbation signal, it may cause the cooling capacity marking perturbation signal to fail to be actually executed by the associated air conditioning equipment, or it may cause the associated air conditioning equipment to enter a state exceeding the allowable operating range. Therefore, even if the corresponding air conditioning zone has a comfort margin that can withstand cooling capacity marking perturbations, the corresponding adjustable control quantity is still deemed unsuitable as a perturbation target. By judging the boundary state of the control quantity, it is possible to... Before applying the cooling capacity marking perturbation signal, control objects lacking adjustable space or posing a risk of exceeding limits are excluded to ensure the subsequent cooling capacity marking perturbation signal is executable on the equipment side and to avoid the perturbation identification process affecting the safe operating boundary of the associated air conditioning equipment. The control command change status is used to determine whether the air conditioning equipment associated with the target air conditioning zone has undergone an active adjustment process that affects the accuracy of perturbation identification within a preset historical observation period. If the chiller unit load, chilled water pump frequency, branch valve opening, terminal valve opening, supply air temperature, or supply air volume changes beyond the normal steady-state fluctuation range of the equipment within the preset historical observation period, it indicates that the associated air conditioning equipment is still in the transitional operation phase after adjustment. This transitional operation phase will cause the host side to output data... The data transmitted from the water network side, the heat exchange data from the terminal side, and the response data from the regional side contain response components caused by the original adjustment actions. Under this condition, when a cold energy labeling perturbation signal is applied, the subsequently extracted cold energy labeling response sequence is difficult to accurately distinguish between the incremental response caused by the cold energy labeling perturbation signal and the continuous response caused by the existing adjustment actions. Therefore, the change amplitude of the control command within the preset historical observation period is compared with the preset equipment stability change threshold. When the associated air conditioning equipment is not in an alarm state, not in a protection interlock state, not in a start-stop switching state, the adjustable control quantity has not reached the control quantity boundary, and the change amplitude of the control command within the preset historical observation period has not exceeded the preset equipment stability change threshold, it is determined that the air conditioning zone meets the equipment-side perturbation availability requirements.After obtaining the comfort margin judgment result, the area-side response stability judgment result, and the equipment-side perturbation availability judgment result, a candidate perturbation identification window is determined. When the corresponding air-conditioning zone has a comfort margin that can withstand cooling capacity marker perturbations, the corresponding air-conditioning zone meets the area-side response stability requirements, and the air-conditioning equipment associated with the corresponding air-conditioning zone meets the equipment-side perturbation availability requirements, a preset time period after the current sampling time is determined as the candidate perturbation identification window. When any one of the comfort margin judgment result, the area-side response stability judgment result, or the equipment-side perturbation availability judgment result does not meet the corresponding requirements, no candidate perturbation identification window is generated, and normal operation monitoring is maintained. The permissible perturbation level is used to limit the allowable perturbation signal of the cooling capacity marker within the candidate perturbation identification window. The permissible disturbance intensity and duration range are defined. The permissible disturbance levels include prohibited disturbance level, low disturbance level, medium disturbance level, and high disturbance level. The prohibited disturbance level indicates that the application of cold energy labeling perturbation signals is not permitted. The low disturbance level indicates that only cold energy labeling perturbation signals with a smaller amplitude and limited duration are permitted. The medium disturbance level indicates that cold energy labeling perturbation signals that meet the normal identification requirements and do not exceed the equipment's stable operating boundary are permitted. The high disturbance level indicates that the comfort margin, regional response stability, and equipment availability within the candidate perturbation identification window are all high, allowing the application of cold energy labeling perturbation signals with a more pronounced identification response but still smaller than the normal scheduling adjustment amplitude. When determining the permissible disturbance level, the upper limit of the comfort margin is considered. The comfort margin level is determined by the upper and lower limit comfort margins; the smaller value between the upper and lower limit comfort margins is selected as the comfort safety constraint, which characterizes the safe distance of the corresponding air-conditioning zone from the nearest comfort boundary; when the comfort safety constraint is small, the comfort margin level is reduced; when the comfort safety constraint is large, the comfort margin level is increased; the regional response stability level is determined based on the temperature change rate and temperature fluctuation amplitude; when the temperature change rate is small and the temperature fluctuation amplitude is small, the regional response stability level is increased; when the temperature change rate is large or the temperature fluctuation amplitude is large, the regional response stability level is reduced; the equipment availability level is determined based on the equipment operating status; when the associated air-conditioning equipment is in stable operation... When the change in operating status and control commands is small and the control quantity has adjustable space from the boundary, the equipment availability level is increased; when the associated air conditioning equipment is not in an alarm state or protection interlock state, but the control quantity is close to the boundary, or the change in control commands is large within the preset historical observation period, the equipment availability level is decreased; the permissible disturbance level of the candidate disturbance identification window is determined based on the comfort margin level, the regional response stability level, and the equipment availability level; after obtaining the comfort margin level, the regional response stability level, and the equipment availability level, the permissible disturbance level of the candidate disturbance identification window is determined according to the lowest level constraint principle; when the comfort margin level is higher than the equipment availability level, the equipment availability level is used as the basis for determining the permissible disturbance level;When the equipment availability level is higher than the regional response stability level, the regional response stability level is used as the basis for determining the permissible disturbance level. When any of the comfort margin level, regional response stability level, and equipment availability level is a prohibited disturbance level, the permissible disturbance level of the candidate disturbance identification window is determined as the prohibited disturbance level. Through this method, the permissible disturbance level of the candidate disturbance identification window is simultaneously constrained by the comfort margin, regional response stability, and equipment executability, thereby reducing the risk of comfort deviation and equipment operation interference caused by directly executing the cold load marking disturbance signal due to a single condition being met. When the permissible disturbance level reaches the preset disturbance execution level, the candidate disturbance identification window is determined. This serves as the perturbation identification window. When the preset perturbation execution level is set to low, the cooling capacity marking perturbation signal is only allowed to be executed within the corresponding candidate perturbation identification window if the perturbation level reaches low, medium, or high. When the permissible perturbation level is lower than the preset perturbation execution level, the candidate perturbation identification window is not designated as a perturbation identification window, and routine operational monitoring of the corresponding air conditioning zone and associated air conditioning equipment continues. By filtering candidate perturbation identification windows through the preset perturbation execution level, the cooling capacity marking perturbation signal is applied only when the comfort margin, zone response stability, and equipment availability all meet the execution requirements, thereby reducing the impact of the perturbation identification process on the comfort of the air conditioning zone. The impact on the stability of air conditioning equipment operation; when outputting the perturbation identification window, the output content includes the window start time, window duration, corresponding air conditioning zone, and allowable perturbation level; the window start time is the start time after the current sampling time when both the regional response stability requirement and the equipment perturbation availability requirement are met simultaneously; the window duration is determined based on the comfort margin maintenance time, the regional response stability duration, the equipment perturbation availability duration, and the preset maximum identification time; the corresponding air conditioning zone is used to identify the target area corresponding to the perturbation identification window, specifically: the continuous duration after the current sampling time when the corresponding air conditioning zone still meets the comfort margin requirement is counted as the comfort margin maintenance time; the corresponding air conditioning zone is counted as the comfort margin maintenance time. The duration for which a zone continuously meets the stability requirements of the regional response is defined as the regional response stability duration. The duration for which the air conditioning equipment associated with the corresponding air conditioning zone continuously meets the equipment-side perturbation availability requirements is defined as the equipment-side perturbation availability duration. The shortest duration among the comfort margin maintenance time, regional response stability duration, equipment-side perturbation availability duration, and preset maximum identification time is determined as the window duration of the perturbation identification window. Perturbation levels are allowed to limit the perturbation amplitude, duration, and direction of subsequent cooling capacity marking perturbation signals. Through the above outputs, subsequent cooling capacity marking perturbation signals can be executed within a defined time range, target air conditioning zone, and perturbation intensity constraints.

[0025] The present invention is further configured such that S3 includes: The target control quantity or a combination of target control quantities is determined from the adjustable control quantities of the air conditioner. The adjustable control quantities of the air conditioner include at least one of the following: chilled water supply temperature setpoint, chilled water pump frequency, branch valve opening, terminal coil valve opening, supply air temperature, and supply air volume. The combination of target control quantities consists of multiple adjustable control quantities of the air conditioner that have the same branch affiliation and act on the same target air conditioning zone. Before applying the cold energy marking perturbation signal, the perturbation start time, perturbation duration, perturbation amplitude, and perturbation direction of the target control quantity or combination of target control quantities are determined based on the window start time, window duration, and allowable perturbation level of the perturbation identification window. Within the perturbation identification window, cold-weighted perturbation signals are applied to the target control quantity or combination of target control quantities according to the perturbation start time, perturbation duration, perturbation amplitude, and perturbation direction; After the cold load indicator disturbance signal reaches the disturbance duration, the target control quantity or target control quantity combination will be restored to the pre-disturbance set value or the reference set value within the allowable operating range of the pre-disturbance set value. The system records the disturbance object, target control quantity or combination of target control quantities, disturbance amplitude, disturbance direction, disturbance start time, disturbance end time, recovery time, corresponding air conditioning zone, and corresponding branch affiliation of the cooling capacity marking perturbation signal; the cooling capacity marking perturbation signal is used to excite the cooling capacity transfer response of the building air conditioning system; specifically, the cooling capacity marking perturbation signal does not aim to directly complete the air conditioning load adjustment as the control objective, but rather, under operating conditions where indoor comfort does not exceed limits, equipment operating stability is not compromised, and protection interlock control is not triggered, it applies a control change to the selected adjustable air conditioning control quantity with limited amplitude and duration, and which can be recovered after the disturbance ends; the... The control change serves as the active stimulus for identifying chilled water transfer, propagating step-by-step along the chiller unit's main unit side, the chilled water network side, the terminal side of the air conditioning unit or fan coil unit, and the area side of the target air conditioning zone. By observing the incremental changes in the control change's output on the main unit side, the water network side's delivery, the terminal side's heat exchange, and the area side's temperature response, a chilled water transfer response that can be distinguished from conventional load regulation results is obtained. Before determining the target control variable, the window start time, window duration, corresponding air conditioning zone, and allowable disturbance level of the perturbation identification window output are obtained, and a list of adjustable control variables associated with the corresponding air conditioning zone is acquired. The adjustable controllable quantity list includes at least one of the following: chilled water supply temperature setpoint, chilled water pump frequency, branch valve opening, terminal coil valve opening, supply air temperature, and supply air volume. The list is established based on the cooling load transfer path, i.e., based on the cooling supply correspondence between the chiller unit, chilled water main, chilled water branches, terminal equipment, and air conditioning zones, controllable quantities that can influence the cooling load transfer of the target air conditioning zone are included in the candidate range. When the target air conditioning zone is cooled by the corresponding chilled water branch and the corresponding terminal equipment, the corresponding branch valve opening, the corresponding terminal coil valve opening, the corresponding terminal supply air temperature, and the corresponding terminal supply air volume are considered as candidate quantities directly related to the target air conditioning zone. Adjustable control variables; when the cooling capacity change of the target air conditioning zone is also affected by the operating status of the chilled water pump, the cooling status of the chilled water main pipe, or the set value of the chilled water supply temperature, the chilled water pump frequency and the set value of the chilled water supply temperature are used as candidate adjustable control variables indirectly associated with the target air conditioning zone; through the above method, the candidate adjustable control variables can all act on the target air conditioning zone along the determined transmission paths of the main unit side, water network side, terminal side, and area side; when multiple air conditioning adjustable control variables in the same perturbation identification window meet the perturbation conditions, the single air conditioning adjustable control variable with a clear correspondence to the cooling capacity transmission path between it and the target air conditioning zone is selected as the target control variable.The defined correspondence of the cooling capacity transfer path means that after a disturbance in the adjustable control quantity of the air conditioner, the resulting change in cooling capacity can be transmitted to the target air conditioning zone along the determined main unit-side output node, water network-side transfer node, terminal-side heat exchange node, and regional-side response node. Furthermore, the transmission path of the cooling capacity change can be traced step-by-step through the unit number, branch number, terminal device number, and air conditioning zone number. If the target air conditioning zone is supplied with cooling capacity by a specific chilled water branch and specific terminal devices, then the branch valve opening of the specific chilled water branch, the terminal coil valve opening of the specific terminal device, and the supply air temperature or supply air volume can all establish a direct transmission correspondence with the target air conditioning zone. The branch valve opening is used to characterize the chilled water inlet... The flow changes in the target branch and the opening of the terminal coil valve are used to characterize the changes in heat exchange conditions when chilled water enters the target terminal heat exchanger. The supply air temperature and supply air volume are used to characterize the changes in the air-side cooling capacity output from the terminal to the target air conditioning zone. When all the above adjustable control quantities meet the disturbance conditions, a single adjustable air conditioning control quantity is preferentially selected as the target control quantity. This reduces the superposition, cancellation, or source mixing of responses caused by simultaneous disturbances from multiple control quantities. This allows for more accurate attribution of each level of response to the current cooling capacity labeling perturbation signal when extracting the incremental responses from the main unit side, water network side, terminal side, and regional side. This improves the identifiability of the cooling capacity labeling response sequence and the reliability of the regional cooling capacity transfer kernel inversion. The disturbance conditions include: a clear cooling capacity transfer path exists between the target control quantity and the target air conditioning zone; the target control quantity has not reached the allowable operating boundary; the target control quantity is stable within a preset historical observation period; after applying a cooling capacity marking perturbation signal according to the preset perturbation amplitude and direction, the indoor temperature of the target air conditioning zone remains within the comfort setting range, and the associated air conditioning equipment does not enter an alarm state, protection interlock state, or start / stop switching state; when the disturbance response of a single adjustable air conditioning control quantity is difficult to achieve a identifiable level, a combination of target control quantities is selected; the target control quantity combination consists of multiple adjustable air conditioning control quantities with the same branch affiliation and acting on the same target air conditioning zone; the response directions of these adjustable air conditioning control quantities are consistent. The consistent response direction means that changes in multiple adjustable control quantities of air conditioners have the same effect on the cooling capacity of the target air conditioning zone. This is to prevent one adjustable control quantity from enhancing cooling while another weakens it, thus avoiding the cancellation of cooling capacity marking responses. During the construction of the target control quantity combination, increasing the opening of the branch valve under the same chilled water branch is combined with increasing the opening of the corresponding terminal coil valve to enhance the cooling capacity delivery response and terminal heat exchange response; or increasing the supply air volume is combined with decreasing the supply air temperature to enhance the identifiable temperature response on the area side. The target control quantity combination does not cross unrelated branches or unrelated air conditioning zones to ensure that the subsequently generated cooling capacity marking response sequence can be accurately attributed to the target air conditioning zone and the corresponding branch.Before applying the cold energy marking perturbation signal, determine the perturbation start time, duration, amplitude, and direction. The perturbation start time is within the perturbation identification window, and a stable observation time is reserved between the perturbation start time and the window start time to ensure the target control quantity remains in a stable setting before the perturbation. The perturbation duration does not exceed the remaining available time of the perturbation identification window and covers the minimum response process required for the target control quantity to be identified by the host side, water network side, terminal side, or regional side after a change. When the permissible perturbation level is low, a smaller perturbation amplitude and shorter perturbation duration are determined. When the permissible perturbation level is high, the perturbation amplitude is increased or the perturbation duration is extended, provided that the perturbation amplitude is less than the normal scheduling adjustment amplitude. The duration of the disturbance is adjusted to enhance the identifiability of the cooling capacity marking response; the disturbance amplitude is determined based on the permissible disturbance level, the current set value of the target control quantity, the permissible operating range of the target control quantity, and the comfort margin of the target air conditioning zone; the disturbance amplitude is greater than the minimum identifiable adjustment of the equipment to ensure that the corresponding equipment can execute the cooling capacity marking micro-disturbance signal; the disturbance amplitude is less than the conventional scheduling adjustment amplitude to distinguish the cooling capacity marking micro-disturbance signal from the conventional scheduling action used to meet load changes; when the target control quantity is the chilled water supply temperature set value, the disturbance amplitude is manifested as a short-term increase or decrease in the set water temperature; when the target control quantity is the chilled water pump frequency, the disturbance amplitude is manifested as a short-term increase or decrease in the frequency; when the target... When the target control quantity is the opening degree of a branch valve or the opening degree of a terminal coil valve, the disturbance amplitude is manifested as a short-term increase or decrease in the valve opening degree; when the target control quantity is the supply air temperature, the disturbance amplitude is manifested as a short-term increase or decrease in the supply air temperature setting; when the target control quantity is the supply air volume, the disturbance amplitude is manifested as a short-term increase or decrease in the air volume setting; the disturbance direction is determined based on the identification purpose and the current comfort margin of the target air conditioning zone; when there is a margin between the current indoor temperature of the target air conditioning zone and the lower limit of the comfort setting range to meet the preset temperature, the disturbance direction is determined as the enhanced cooling direction, which includes reducing the chilled water supply temperature setting value, increasing the chilled water pump frequency, and increasing the... The opening degree of branch valves, increasing the opening degree of terminal coil valves, decreasing the supply air temperature, or increasing the supply air volume are used to make the cooling capacity enhancement process form a recognizable response along the main unit side, water network side, terminal side, and zone side; when there is a preset temperature margin between the current indoor temperature of the target air conditioning zone and the upper limit of the comfort setting range, the disturbance direction is determined as the cooling supply weakening direction. The cooling supply weakening direction includes increasing the chilled water supply temperature setting value, decreasing the chilled water pump frequency, decreasing the opening degree of branch valves, decreasing the opening degree of terminal coil valves, increasing the supply air temperature, or decreasing the supply air volume, to make the cooling capacity weakening process form a recognizable temperature change on the zone side; the determination of the disturbance direction is constrained by the expectation that the indoor temperature after the disturbance will still be within the comfort setting range;After determining the disturbance start time, duration, amplitude, and direction, a cooling capacity marking disturbance signal is applied to the target control quantity or combination of target control quantities within the disturbance identification window. When applying the cooling capacity marking disturbance signal, a temporary control command is sent to the corresponding equipment according to the disturbance start time, causing the target control quantity to undergo a short-term control change according to the predetermined disturbance direction and amplitude. When the target control quantity is a combination of target control quantities, the control platform sends associated control commands to each control quantity in the target control quantity combination according to the same disturbance identifier, causing each control quantity in the target control quantity combination to complete the disturbance action within the same or matching time range, and ensuring that each disturbance action belongs to the same target air conditioning zone and the same branch. Relationship; During the disturbance application period, actively adjust and limit other air conditioning adjustable control quantities unrelated to the target control quantity or combination of target control quantities; the active adjustment and limitation does not exclude the priority execution of equipment protection control, comfort overrun correction control, and safety interlock control; if equipment protection control, comfort overrun correction control, and safety interlock control are not triggered, the active optimization adjustment of unrelated air conditioning adjustable control quantities is suspended; when a cooling capacity marking perturbation signal is applied to the branch valve opening, the active adjustment of unrelated branch valves, the terminal air supply volume of other air conditioning zones, and the main unit load is limited to reduce the impact of changes in unrelated control quantities on the regional response attribution results; when equipment protection control, comfort overrun correction control, or safety interlock control is triggered during the disturbance application period. During the initial setup, corresponding protection controls are allowed to be executed first, and the current cold energy marking perturbation signal is marked as a record subject to external control interference. In subsequent regional cold energy transfer kernel inversion processes, records subject to external control interference are excluded as invalid samples to reduce the impact of external control interference on the reliability of the regional cold energy transfer kernel. After the cold energy marking perturbation signal reaches the perturbation duration, the target control quantity or combination of target control quantities is restored to the pre-perturbation setpoint, or restored to the baseline setpoint within the allowable operating range of the pre-perturbation setpoint. When the pre-perturbation setpoint still meets the current equipment operating boundary and target air conditioning zone comfort requirements, restoration to the pre-perturbation setpoint is prioritized. If the building air conditioning system operating conditions change during the perturbation process, causing the pre-perturbation setpoint to no longer be valid, the system will be restored to its previous value. When the current equipment operating boundary or the comfort requirements of the target air conditioning zone are met, the system restores the system to the baseline setting value within the allowable operating range of the pre-disturbance setting value. The restoration process is executed step by step according to a preset restoration step size to reduce the possibility of unmarked responses caused by sudden changes in the target control quantity. The cooling capacity marking perturbation signal record includes the perturbation object, the target control quantity or a combination of target control quantities, the perturbation amplitude, the perturbation direction, the perturbation start time, the perturbation end time, the restoration time, the corresponding air conditioning zone, and the corresponding branch affiliation. The perturbation object is used to identify the equipment or control node to which the perturbation is applied. The target control quantity is used to identify the control parameter that has undergone a short-term control change. The perturbation amplitude and perturbation direction are used to characterize the degree and direction of change of the target control quantity.The disturbance start time, disturbance end time, and recovery time are used to determine the truncation range of subsequent response segments; the corresponding air conditioning zone is used to identify the target area of ​​the cooling capacity marking perturbation signal; the corresponding branch affiliation is used to identify the cooling capacity transfer path corresponding to the cooling capacity marking perturbation signal; when using a target control quantity combination, the cooling capacity marking perturbation signal record also includes the synchronization relationship or sequence relationship between each control quantity within the target control quantity combination.

[0026] The present invention is further configured such that S4 includes: Using the disturbance start time of the cold energy marker perturbation signal as the time reference, a data segment located before the disturbance start time and lasting for a preset duration is extracted from the multi-level cold energy transfer data as the pre-disturbance running segment. Stability verification is performed on the operation segment before the disturbance. When the changes in the main unit output data, water network transmission data, terminal heat exchange data and regional response data in the operation segment before the disturbance do not exceed the corresponding preset benchmark fluctuation threshold, the operation segment before the disturbance is determined as the benchmark state. The response observation time window is determined based on the disturbance start time, disturbance end time, and recovery time of the cold energy labeled perturbation signal; Data within the response observation time window is extracted from the multi-level cold energy transfer data as response segments. The differences between the main unit output data, water network transfer data, terminal heat exchange data and regional response data in the response segments and the corresponding level data in the baseline state are extracted to obtain the main unit incremental response, water network incremental response, terminal incremental response and regional incremental response. Following the order of cooling capacity transfer from the main unit side, water network side, terminal side, and regional side, incremental responses from the main unit side, water network side, terminal side, and regional side that share the same cooling capacity marker perturbation signal identifier, the same corresponding air conditioning zone, and the same branch affiliation are sequentially correlated to generate a cooling capacity marker response sequence. Specifically, the cooling capacity marker response sequence characterizes the process by which cooling capacity changes after the application of the cooling capacity marker perturbation signal are transmitted step by step from the main unit side through the water network side and terminal side to the target air conditioning zone, forming a regional side response. When determining the operating segment before the perturbation, the perturbation start time in the cooling capacity marker perturbation signal record is used as the time reference, and a continuous data segment of a preset duration is extracted forward along the time axis from the multi-level cooling capacity transfer data as the perturbation. The pre-disturbance operating segment is located before the application of the cold energy marking perturbation signal and simultaneously includes the host-side output data, water network-side transmission data, terminal-side heat exchange data, and regional-side response data related to the cold energy transmission path corresponding to this cold energy marking perturbation signal. This pre-disturbance operating segment characterizes the baseline operating state during the cold energy transmission process along the host side, water network side, terminal side, and regional side when the target control variable has not yet been disturbed. After extracting the pre-disturbance operating segment, a stability check is performed on it. The stability check is used to determine whether the pre-disturbance operating segment can serve as the baseline state for subsequent difference extraction. Specifically, the host-side output data, water network-side transmission data, and terminal-side heat exchange data within the pre-disturbance operating segment are processed separately. Fluctuation identification is performed on thermal data and regional response data. When identifying fluctuations in the main unit's output data, the chiller unit's load rate, cooling output, chilled water supply temperature, chilled water return temperature, and unit power are continuously monitored during the pre-disturbance operating period to determine if the chiller unit is in a stable cooling output state. When identifying fluctuations in water network-side transmission data, the chilled water pump frequency, chilled water flow rate, network supply and return water pressure difference, branch valve opening, branch flow rate, chilled water supply and return water temperature difference, and return water response status are continuously monitored during the pre-disturbance operating period to determine if the chilled water transmission process is in a stable transmission state. When identifying fluctuations in terminal-side heat exchange data, the supply air temperature, return air temperature, supply air volume, coil valve opening, and airflow are monitored. The continuous change of the generator frequency during the operation segment before the disturbance is used to determine whether the terminal equipment is in a stable heat exchange state. When identifying fluctuations in the regional response data, the continuous change of the indoor temperature and temperature change rate of the target air-conditioning zone during the operation segment before the disturbance is used to determine whether the target air-conditioning zone is in a stable thermal response state. When the change amplitudes of the generator output data, water network transmission data, terminal heat exchange data, and regional response data during the operation segment before the disturbance do not exceed the corresponding preset benchmark fluctuation thresholds, it is determined that the generator cooling output state, water network transmission state, terminal heat exchange state, and regional temperature response state before the application of the cooling capacity marking perturbation signal all meet the benchmark stability requirements, and the operation segment before the disturbance is determined as the benchmark state.The reference state is not instantaneous data at a single sampling moment, but a stable reference state formed by continuous sampling data within the operating segment before the disturbance. For each type of data—host-side output data, water network-side transmission data, terminal-side heat exchange data, and regional-side response data—the reference value and reference change trend of the corresponding data item are determined based on the continuous sampling results within the operating segment before the disturbance. The reference value is used to characterize the stable operating level of the corresponding data item before the application of the cold energy labeling perturbation signal. The reference change trend is used to characterize the slight upward trend, slight downward trend, or stable trend of the corresponding data item under natural operating conditions before the application of the cold energy labeling perturbation signal. In the subsequent difference extraction process, the reference state is used as the response. The comparison of segments identifies continuous deviations from the baseline value and baseline change trend in the response segment as incremental changes caused by the cold energy marker perturbation signal. When determining the response observation time window, the data truncation range of the response segment is determined based on the disturbance start time, disturbance end time, and recovery time recorded in the cold energy marker perturbation signal. The response observation time window includes a disturbance duration phase, a disturbance recovery phase, and a regional response delay phase. The disturbance duration phase is the time period between the disturbance start time and the disturbance end time, used to collect the changes in the host-side output data, water network-side transmitted data, and terminal-side heat exchange data when the target control variable is in a short-term disturbance state. The disturbance recovery phase... The period between the end of the disturbance and the recovery time is used to collect the data at each level during the recovery process of the target control quantity from the disturbance state to the pre-disturbance setpoint or baseline setpoint, including the decline, stabilization, or reverse change. The regional response delay stage is a period of time after the recovery time that continues for a preset response delay duration, used to collect the delayed temperature response formed in the target air conditioning zone after the cooling capacity is transported through the chilled water network, heat exchanged by terminal equipment, and mixed with regional air. The regional response delay stage is set to collect the delayed temperature response of the target air conditioning zone after the end of the cooling capacity marker perturbation signal due to the lag in cooling capacity transfer, the lag in terminal heat exchange, and regional thermal inertia, so that the response observation time window covers the cooling capacity marker perturbation signal. The system demonstrates the complete response process from changes in control variables, the delivery of cooling capacity along the transmission path, heat exchange at terminal equipment, to changes in the indoor temperature of the area. After determining the response observation time window, data within the response observation time window is extracted from the multi-level cooling capacity transmission data as a response segment. The response segment needs to be consistent with the corresponding air conditioning zone, the corresponding branch affiliation, and the target control variable in the cooling capacity marking perturbation signal record. When the cooling capacity marking perturbation signal acts on a specific chilled water branch, the response segment includes the branch valve opening, branch flow rate, branch supply and return water status, terminal equipment operation data connected to the chilled water branch, and the area-side response data of the air conditioning zone served by the chilled water branch.When the cooling capacity perturbation signal is applied to a specific terminal device, the response segment includes the coil valve opening, supply air temperature, return air temperature, supply air volume, fan frequency, and the indoor temperature and temperature change rate of the corresponding air conditioning zone of the terminal device. When the target control quantity is the chilled water pump frequency, the response segment includes changes in chilled water pump frequency, changes in total chilled water flow, changes in supply and return water pressure difference in the pipe network, changes in flow of relevant branches, relevant terminal heat exchange data, and the area-side response data of the target air conditioning zone. When the target control quantity is the chilled water supply temperature setpoint, the response segment includes the chilled water supply temperature on the chiller side, chilled water return temperature, cooling capacity output, unit power, supply and return water temperature difference on the water network side, and relevant terminal heat exchange data. And the regional response data of the target air conditioning zone; by limiting the response segment according to the corresponding air conditioning zone, the corresponding branch affiliation and the target control quantity, it can be ensured that the subsequent incremental response of the host side, the water network side, the terminal side, and the regional side all originate from the same cooling capacity transfer path, thus providing a data basis for judging whether the cooling capacity marking perturbation signal takes effect step by step along the host side, the water network side, the terminal side, and the regional side; the host side output data, the water network side transfer data, the terminal side heat exchange data and the regional side response data in the response segment are compared with the reference values ​​and reference change trends of the corresponding levels in the reference state, that is, difference extraction. When the data of a certain level in the response segment is relative to the corresponding reference value and reference change, the difference is extracted. When a continuous deviation occurs in the cooling trend, and this continuous deviation corresponds to the perturbation direction of the cooling capacity marker perturbation signal, the continuous deviation is determined to be an incremental change caused by the cooling capacity marker perturbation signal. An incremental response is generated based on the incremental change in the output data from the host side, an incremental response is generated based on the incremental change in the data transmitted from the water network side, an incremental response is generated based on the incremental change in the heat exchange data from the terminal side, and an incremental response is generated based on the incremental change in the response data from the regional side. After obtaining the incremental responses at each level, a time-series correlation is performed according to the cooling capacity transfer order of the host side, water network side, terminal side, and regional side. This time-series correlation is used to determine whether the same cooling capacity marker perturbation signal follows a preset cooling capacity transfer path sequentially. A response is generated. In specific processing, the response segment corresponding to the current cooling capacity mark perturbation signal is determined according to the identifier of the cooling capacity mark perturbation signal. According to the corresponding air conditioning zone and the corresponding branch affiliation, incremental responses from the host side, water network side, terminal side, and regional side belonging to the same cooling capacity transfer path are selected from the response segment. According to the response occurrence time of each level of incremental response, the incremental responses from the host side, water network side, terminal side, and regional side are arranged in sequence. When the incremental responses corresponding to the same cooling capacity mark perturbation signal appear in the order of host side or water network side, terminal side, and regional side, the data corresponding to the cooling capacity mark perturbation signal is determined as a complete cooling capacity transfer response chain.During the time-series correlation process, each level of incremental response is labeled with its response occurrence time, response duration, and response decay time relative to the disturbance initiation time. The response occurrence time characterizes the time when the data item at the corresponding level begins to generate identifiable incremental changes; the response duration characterizes the length of time the incremental change at the corresponding level remains in an identifiable state; and the response decay time characterizes the time process during which the incremental change at the corresponding level gradually returns from an identifiable state to near the baseline state. Based on the response occurrence time, response duration, and response decay time, the propagation delay of the cold energy labeling perturbation signal between the host side, water network side, terminal side, and regional side is determined. The system identifies the timing relationship and determines whether there is response lag, response attenuation, or response interruption in the cooling capacity transfer path. When generating the cooling capacity-marked response sequence, incremental responses from the main unit side, water network side, terminal side, and regional side that share the same cooling capacity-marked perturbation signal identifier, the same corresponding air conditioning zone, and the same branch affiliation are organized into response sequence units. Each response sequence unit includes the cooling capacity-marked perturbation signal identifier, the target control quantity or a combination of target control quantities, the perturbation start time, the perturbation end time, the recovery time, the main unit side incremental response, the water network side incremental response, the terminal side incremental response, the regional side incremental response, and the temporal relationship between the incremental responses at each level.

[0027] The present invention is further configured such that S5 includes: The target control quantity or combination of target control quantities, disturbance amplitude and disturbance direction in the cold energy label perturbation signal record are determined as control excitations, and the incremental response on the host side, the incremental response on the water network side, the incremental response on the terminal side and the incremental response on the regional side in the cold energy label response sequence are determined as response results. According to the corresponding air conditioning zone and corresponding branch affiliation, the control excitation and response results corresponding to the same cooling capacity marker perturbation signal are matched to establish the response mapping relationship between the air conditioning adjustable control quantity and the air conditioning zone. Based on the response occurrence time, peak response amplitude, response duration, and response decay process of the incremental response on the regional side in the cold energy label response sequence, as well as the disturbance start time and disturbance amplitude of the corresponding cold energy label perturbation signal, the arrival time of the action of the target control quantity on the corresponding air conditioning zone, the intensity of cold energy transfer, and the regional cold storage capacity are determined. Based on the relationship between the incremental response amplitudes of the main unit side, the water network side, the terminal side, and the regional side in the sequence of cooling capacity transfer, the degree of transfer attenuation of the target control quantity to the corresponding air conditioning zone is determined. When multiple adjustable air conditioning control quantities act on the same air conditioning zone under the same branch affiliation, the action coupling relationship between the multiple adjustable air conditioning control quantities is determined based on the deviation relationship between the area-side incremental response corresponding to a single adjustable air conditioning control quantity and the area-side incremental response corresponding to the combination of target control quantities. The arrival time of actions, cold energy transfer intensity, transfer attenuation degree, regional cold storage capacity, and action coupling relationship are associated and stored according to air conditioning zones, branch affiliations, and adjustable control quantities of air conditioning systems to form a regional cold energy transfer core for the corresponding air conditioning zone. Specifically, the inversion process of the regional cold energy transfer core is used to form the cold energy transfer characteristics of the corresponding air conditioning zone based on the cold energy marker perturbation signal and the cold energy marker response sequence. In this process, the target control quantity or combination of target control quantities, perturbation amplitude, and perturbation direction corresponding to the cold energy marker perturbation signal are used as control excitations, and the incremental responses of the host side, water network side, terminal side, and regional side in the cold energy marker response sequence are used as response results. According to the corresponding air conditioning... The system establishes a cooling response mapping relationship between adjustable air conditioning control quantities and air conditioning zones by defining the zoning, corresponding branch affiliation, and cooling capacity transfer sequence. Before establishing the response mapping relationship, it acquires cooling capacity marking perturbation signal records and corresponding cooling capacity marking response sequences. The cooling capacity marking perturbation signal records include the target control quantity or a combination of target control quantities, perturbation amplitude, perturbation direction, perturbation start time, perturbation end time, recovery time, corresponding air conditioning zone, and corresponding branch affiliation. The target control quantity or combination of target control quantities is used to identify the adjustable air conditioning control quantity that triggers the current cooling capacity marking perturbation signal. The perturbation amplitude and perturbation direction are used to identify the degree of short-term change in the adjustable air conditioning control quantity during the perturbation process. The short-term change direction; the disturbance start time, disturbance end time, and recovery time are used to define the application time range, end time node, and control quantity recovery time node of this cold energy marking perturbation signal; the corresponding air conditioning zone is used to identify the target area of ​​this cold energy marking perturbation signal; the corresponding branch affiliation is used to identify the chilled water branch, terminal equipment, and regional response path that this cold energy marking perturbation signal is expected to pass through; the cold energy marking response sequence includes the main unit side incremental response, water network side incremental response, terminal side incremental response, and regional side incremental response, which are used to characterize the actual response process formed sequentially by the same cold energy marking perturbation signal on the main unit side, water network side, terminal side, and regional side, and to provide a basis for subsequent control excitation to each level. The response results are matched to provide a data foundation; when determining the control excitation, the target control quantity or combination of target control quantities in the cold energy mark perturbation signal record is determined as the excitation object, the perturbation amplitude is determined as the excitation intensity, and the perturbation direction is determined as the excitation direction; when the target control quantity is the chilled water supply temperature setpoint, the control excitation is used to characterize the short-term increase or decrease of the chilled water supply temperature setpoint; when the target control quantity is the chilled water pump frequency, the control excitation is used to characterize the short-term increase or decrease of the chilled water delivery capacity; when the target control quantity is the branch valve opening, the control excitation is used to characterize the short-term increase or decrease of the flow capacity of the corresponding chilled water branch.When the target control variable is the opening degree of the terminal coil valve, the control excitation is used to characterize the short-term increase or decrease in the flow rate of chilled water entering the terminal coil; when the target control variable is the supply air temperature, the control excitation is used to characterize the short-term increase or decrease in the cooling temperature on the terminal air side; when the target control variable is the supply air volume, the control excitation is used to characterize the short-term increase or decrease in the delivery capacity on the terminal air side; when using a combination of target control variables, the disturbance amplitude, disturbance direction, and disturbance timing of each adjustable control variable of the air conditioning system within the target control variable combination are jointly determined as the combined control excitation; when determining the response result, the incremental response on the host side in the cooling capacity-marked response sequence is used. The incremental responses on the water network side, the terminal side, and the regional side are used as response results. The incremental response on the main unit side is used to characterize the changes in the main unit side operating status caused by the chiller load rate, chiller output, chilled water supply temperature, chilled water return temperature, and unit power by the chiller capacity labeled perturbation signal. The incremental response on the water network side is used to characterize the changes in the water network side transmission status caused by the chiller capacity labeled perturbation signal on the chilled water pump frequency, chilled water flow rate, supply and return water pressure difference, branch valve opening, branch flow rate, chilled water supply and return water temperature difference, and return water response time. The incremental response on the terminal side is used to characterize the changes in the supply air temperature, return air temperature, supply air volume, coil valve opening, and fan frequency caused by the chiller capacity labeled perturbation signal. The terminal-side heat exchange state changes; the regional-side incremental response is used to characterize the regional-side response changes of the indoor temperature and temperature change rate of the target air-conditioning zone relative to the baseline state; when establishing the response mapping relationship, the control excitation corresponding to the same cooling capacity marking perturbation signal is matched with the response result according to the corresponding air-conditioning zone and the corresponding branch affiliation; the data range corresponding to the same perturbation is determined according to the cooling capacity marking perturbation signal identifier; the chilled water branch and terminal equipment corresponding to the cooling capacity marking perturbation signal are determined according to the corresponding branch affiliation; the target response area corresponding to the cooling capacity marking perturbation signal is determined according to the corresponding air-conditioning zone; the control excitation of the cooling capacity marking perturbation signal is matched with the host-side incremental response under the same cooling capacity transfer path. The incremental responses from the air conditioning system, water network side, terminal side, and regional side are correlated to form a response mapping relationship between the adjustable control quantity of the air conditioning system and the air conditioning zone. This response mapping relationship is used to characterize the process by which the cooling capacity change is transmitted to the target air conditioning zone along the corresponding cooling capacity transmission path after a short-term change in the adjustable control quantity of the air conditioning system, as well as the response state formed by the cooling capacity change at the main unit side, water network side, terminal side, and regional side. The action arrival time is used to characterize the time required for the target air conditioning zone to form an identifiable regional side response after the target control quantity is disturbed. When determining the action arrival time, the moment when the indoor temperature change or the rate of temperature change first reaches the identifiable response requirement is first retrieved from the regional side incremental response.The identifiable response requirement is determined based on the temperature sensor accuracy, the natural fluctuation level of the indoor temperature in the area, and the baseline state before the disturbance. This is used to eliminate sampling noise, instantaneous abnormal fluctuations, and short-term changes unrelated to the cooling capacity marker perturbation signal. The moment when the incremental response on the area side first reaches the identifiable response requirement is compared with the disturbance start time of the cooling capacity marker perturbation signal, and the time interval between the two is determined as the arrival time of the target control quantity's action on the corresponding air conditioning zone. The cooling capacity transfer intensity is used to characterize the ability of the target control quantity's disturbance to effectively improve the temperature of the corresponding air conditioning zone. When determining the cooling capacity transfer intensity, the peak response amplitude, response duration, and disturbance amplitude of the corresponding cooling capacity marker perturbation signal in the incremental response on the area side are obtained. The response amplitude characterizes the maximum identifiable temperature change in the target air conditioning zone after the current perturbation; the response duration characterizes the length of time the incremental change in the regional response data remains in an identifiable state; the perturbation amplitude characterizes the degree of change in the current control excitation; when the perturbation amplitude is not higher than a preset perturbation amplitude threshold, the peak response amplitude is not lower than a preset peak response threshold, and the response duration is not lower than a preset response duration threshold, the cooling capacity transfer intensity of the target control quantity to the air conditioning zone is determined to be at a high intensity level; when the perturbation amplitude is higher than a preset perturbation amplitude threshold, and the peak response amplitude is lower than a preset peak response threshold or the response duration is lower than a preset response duration threshold, the cooling capacity transfer intensity of the target control quantity to the air conditioning zone is determined to be at a high intensity level. The cold energy transfer intensity is determined to be at a low intensity level; in other cases, the cold energy transfer intensity of the target control variable to the air-conditioning zone is determined to be at a medium intensity level; the zone cold storage capacity is used to characterize the ability of the target air-conditioning zone to maintain an improved indoor temperature state after receiving cold energy; when determining the zone cold storage capacity, the recovery time of the cold energy marker perturbation signal is taken as the starting point, and the zone-side incremental response after the recovery time is taken as the response decay process, and the response decay time, temperature recovery rate, and temperature improvement maintenance time are determined; the response decay time is the time it takes for the zone-side incremental response to fall back from the peak response state to near the reference state; the temperature improvement maintenance time is the duration for the indoor temperature of the target air-conditioning zone to maintain an improved state relative to the reference state. The duration of the response decay is defined as follows: the temperature recovery rate is the rate at which the indoor temperature of the target air-conditioning zone recovers during the response decay process. When the response decay time meets the preset decay time requirement, the temperature improvement maintenance time meets the preset maintenance time requirement, and the temperature recovery rate does not exceed the preset recovery rate threshold, the target air-conditioning zone is determined to have high cold storage capacity. When some parameters among the response decay time, temperature improvement maintenance time, and temperature recovery rate meet the corresponding preset requirements, the target air-conditioning zone is determined to have medium cold storage capacity. When the response decay time does not meet the preset decay time requirement, the temperature improvement maintenance time does not meet the preset maintenance time requirement, or the temperature recovery rate exceeds the preset recovery rate threshold, the target air-conditioning zone is determined to have low cold storage capacity.The transmission attenuation level is used to characterize the weakening of the response amplitude during the stepwise transmission of the cold energy labeled perturbation signal along the host side, water network side, terminal side, and regional side. To determine the transmission attenuation level, the amplitude variation relationship and response occurrence time relationship of the incremental responses at the host side, water network side, terminal side, and regional side are extracted according to the cold energy transmission sequence. When the incremental responses at the host side, water network side, terminal side, and regional side all meet the corresponding identifiable requirements, and a continuous time correspondence is maintained between the incremental responses at each level, the transmission attenuation level is determined to be low. When the incremental response at the host side or water network side meets the identifiable requirement, and the incremental response at the terminal side meets the requirement for low attenuation, the transmission attenuation level is determined to be low. If the identification requirement is met, but the incremental response on the regional side is lower than the corresponding identification requirement, or the incremental response on the regional side is significantly weaker than the incremental response on the terminal side, the transmission attenuation is determined to be medium attenuation, and the attenuation location is determined to be between the terminal side and the regional side. If the incremental response on the main unit side or the water network side meets the identification requirement, but the incremental response on the terminal side is lower than the corresponding identification requirement, the transmission attenuation is determined to be high attenuation, and the attenuation location is determined to be between the water network side and the terminal side. If the incremental response on the water network side is lower than the corresponding identification requirement, it is determined that there is high attenuation in the cold energy transmission between the main unit side and the water network side. After determining the cold energy transmission intensity level, the regional cold storage capacity level, and the transmission attenuation level, the preset levels can be used. The mapping relationship converts each level into a corresponding level label or leveled value; among them, the leveled value corresponding to the high intensity level is higher than that of the medium intensity level, and the leveled value corresponding to the medium intensity level is higher than that of the low intensity level; the leveled value corresponding to the high cold storage capacity is higher than that of the medium cold storage capacity, and the leveled value corresponding to the medium cold storage capacity is higher than that of the low cold storage capacity; the leveled value corresponding to the low attenuation is better than that of the medium attenuation, and the leveled value corresponding to the medium attenuation is better than that of the high attenuation; when determining the action coupling relationship, the deviation relationship is compared between the regional side incremental response corresponding to a single air conditioning adjustable control quantity and the regional side incremental response corresponding to the target control quantity combination; when multiple air conditioning adjustable control quantities have the same branch affiliation relationship and act on... In the same air conditioning zone, when the regional incremental response corresponding to each individual air conditioning adjustable control quantity and the regional incremental response corresponding to the target control quantity combination have been obtained, the expected combined response is determined based on the regional incremental response corresponding to each individual air conditioning adjustable control quantity, and the regional incremental response corresponding to the target control quantity combination is compared with the expected combined response; when the regional incremental response corresponding to the target control quantity combination is stronger than the expected combined response, the action coupling relationship between multiple air conditioning adjustable control quantities is determined to be a strengthening relationship; when the regional incremental response corresponding to the target control quantity combination is weaker than the expected combined response, the action coupling relationship between multiple air conditioning adjustable control quantities is determined to be a canceling relationship or a mutually restrictive relationship.When the incremental response of the region corresponding to the target control quantity combination matches the expected combined response, the action coupling relationship between multiple air conditioning adjustable control quantities is determined to be a weak coupling relationship. This action coupling relationship reflects the impact of different air conditioning adjustable control quantities acting together on the target air conditioning zone response. When forming a region cooling capacity transfer kernel, the action arrival time, cooling capacity transfer intensity, transfer attenuation degree, region cooling storage capacity, and action coupling relationship are associated and stored according to air conditioning zone, branch affiliation, and air conditioning adjustable control quantity. When the target control quantity combination participates in the inversion, the combined response relationship between the target control quantity combination and the corresponding air conditioning zone is associated and stored. This is considered as part of the action coupling relationship. Through the above processing, the cold energy marker perturbation signal and the cold energy marker response sequence are transformed into a regional cold energy transfer kernel between the air conditioning adjustable control quantity and the air conditioning zone. The regional cold energy transfer kernel is used to characterize the reachability of the effect of the air conditioning adjustable control quantity change on the target air conditioning zone, the action arrival time of the cold energy change to the target air conditioning zone, the degree of transmission attenuation of the cold energy change during the transmission process along the main unit side, water network side, terminal side and regional side, the regional cold storage capacity of the target air conditioning zone to maintain the temperature improvement state after receiving the cold energy, and the enhancement or cancellation relationship formed when multiple air conditioning adjustable control quantities act together on the same target air conditioning zone.

The short-cycle cooling load forecast results include the predicted cooling load demand and the predicted load occurrence period. Based on the matching relationship between the predicted load occurrence period and the action arrival time in the corresponding area's cooling capacity transfer core, the cooling capacity response time status of the corresponding air conditioning zone is determined. Based on the matching relationship between the predicted cooling load demand and the cooling intensity, attenuation degree and cold storage capacity of the corresponding area's cooling core, the cooling capacity of the corresponding air conditioning zone is determined to be in a suitable state. Based on the cooling capacity response time status and the cooling capacity reaching the adaptation status, the corresponding air conditioning zones are marked as easily adjustable load areas or load transfer restricted areas. When the predicted cooling load demand of the corresponding air conditioning zone is lower than the preset load threshold, and the indoor temperature of the air conditioning zone deviates from the comfort setting range within a preset duration, and the cooling transfer intensity in the corresponding area's cooling transfer core is lower than the preset transfer intensity threshold or the transfer attenuation degree is higher than the preset attenuation threshold, the air conditioning zone is marked as an area with insufficient cooling capacity. Based on easily adjustable load areas, transfer-constrained load areas, and areas with insufficient cooling capacity, cooling capacity arrival capacity markers, adjustment priority markers, and cooling mode markers are added to the short-cycle cooling load forecast results for each air conditioning zone to generate forecast load results corrected by the transfer kernel. Specifically, the combination of short-cycle cooling load forecast results and regional cooling capacity transfer kernels is used to transform the forecast load results into forecast load results with cooling capacity arrival capacity constraints. When obtaining short-cycle cooling load forecast results, a load forecast sample sequence is constructed based on historical cooling load data, regional environmental data, personnel activity data, and meteorological data. This load forecast sample sequence is then input into a pre-trained short-cycle load forecast model to generate forecast load results for each air conditioning zone in the future short cycle. The system predicts the cooling load demand and the predicted load occurrence periods within the time domain. The short-cycle load prediction model is based on time-series variation characteristics and is used to output the predicted cooling load demand and its corresponding predicted load occurrence periods within the future prediction period, according to the correspondence between historical cooling load changes, regional environmental changes, changes in human activity, and meteorological changes. The historical cooling load data characterizes the cooling demand variation patterns of the corresponding air-conditioned zones under similar time conditions, similar seasonal conditions, and similar operating conditions. The regional environmental data characterizes the current indoor temperature, temperature change rate, comfort setting range, and regional thermal response status. The human activity data characterizes human density and regional activation status. The impact of changes in access control and meeting room usage on changes in internal heat sources; the meteorological data is used to characterize the impact of changes in outdoor temperature, outdoor humidity, solar radiation, and weather forecasts on changes in the building's external heat load; the short-cycle cooling load forecast result generated by combining historical cooling load data, regional environmental data, personnel activity data, and meteorological data includes at least the predicted cooling load demand for the corresponding air-conditioning zone in the future forecast period, and the predicted load occurrence period corresponding to the predicted cooling load demand; the predicted cooling load demand is used to characterize the cooling capacity that the target air-conditioning zone needs to meet during the predicted load occurrence period; the predicted cooling load demand includes the cooling capacity required to maintain the target air-conditioning zone within the comfort setting range, and the target air-conditioning zone's cooling capacity requirements. The adjustment zone is required to increase, maintain, or decrease its cooling demand relative to the current cooling state; the predicted load occurrence period is used to characterize the future time range in which the predicted cooling load demand will occur and needs to be met; when determining the cooling capacity response timeliness, the predicted load occurrence period is matched with the action arrival time in the regional cooling capacity transfer core; specifically, based on the current time or the time when it can be issued and the action arrival time of the corresponding available control action, the arrival time of the cooling capacity effect expected to reach the target air conditioning zone is determined; when the arrival time is before the predicted load occurrence period or within the acceptable time range of the predicted load occurrence period, it is determined that the cooling capacity response timeliness of the control path corresponding to the air conditioning zone meets the timeliness requirements;By determining the cooling load response timeliness, subsequent scheduling processes can simultaneously consider both the predicted cooling load demand and the actual time required for cooling load to reach the target air conditioning zone, avoiding the generation of scheduling actions solely based on the predicted cooling load demand. When determining the cooling load arrival adaptation state, the predicted cooling load demand is matched with the cooling load transfer intensity, transfer attenuation degree, and regional cold storage capacity in the corresponding area's cooling load transfer core. When the cooling load transfer intensity meets the predicted cooling load demand, the transfer attenuation degree is within the preset attenuation allowable range, and the regional cold storage capacity meets the preset temperature maintenance requirements, the cooling load arrival adaptation state of that air conditioning zone is determined to meet the requirements. When marking areas based on the cooling load response timeliness and cooling load arrival adaptation state, if the action corresponding to a certain air conditioning zone... If the arrival time meets the requirements of the predicted load occurrence period, the cold energy transfer intensity meets the predicted cooling load demand, the transfer attenuation is within the preset attenuation allowable range, and the area's cold storage capacity meets the preset temperature maintenance requirements, then the air conditioning zone is marked as an easily adjustable load zone. The easily adjustable load zone characterizes the fact that the predicted cooling load demand of the air conditioning zone can be effectively met during the predicted load occurrence period through existing control actions. If the arrival time of the corresponding action for an air conditioning zone does not meet the timeliness requirements of the predicted load occurrence period, or the cold energy transfer intensity is lower than the transfer capacity required to cover the predicted cooling load demand, or the transfer attenuation exceeds the corresponding preset attenuation allowable range, or the area's cold storage capacity does not meet the preset temperature maintenance requirements, then the air conditioning zone is marked as an easily adjustable load zone. Zones are marked as load-limited areas; these load-limited areas characterize situations where the air conditioning zone experiences delayed cooling arrival, insufficient cooling capacity, significant attenuation during cooling capacity transfer, or difficulty in maintaining the improved temperature state. The determination of insufficient cooling arrival areas identifies air conditioning zones where the predicted cooling load demand is lower than a preset load threshold, but the actual indoor temperature consistently deviates from the comfort setting range. When the predicted cooling load demand for a corresponding air conditioning zone is lower than the preset load threshold, it indicates that the air conditioning zone does not have a high cooling demand during the predicted load period. When the indoor temperature of a corresponding air conditioning zone consistently exceeds the upper limit of the comfort setting range or consistently falls below the lower limit of the comfort setting range for a preset duration, it indicates that the air conditioning zone has already experienced [a certain issue / problem]. An abnormal comfort state is detected. Based on this, the corresponding area's cooling capacity transfer core is invoked. If the cooling capacity transfer intensity is lower than a preset transfer intensity threshold, or the transfer attenuation is higher than a preset attenuation threshold, it indicates that the abnormal comfort state is more likely due to insufficient cooling capacity reaching the target air conditioning zone than to excessive predicted cooling load demand. The air conditioning zone is then marked as a region with insufficient cooling capacity. After marking easily adjustable load areas, transfer-limited load areas, and regions with insufficient cooling capacity, cooling capacity arrival capacity, adjustment priority, and cooling mode labels are added to the short-cycle cooling load prediction results of each air conditioning zone. The cooling capacity arrival capacity label is used to characterize the probability that the predicted cooling load demand of the corresponding air conditioning zone will be effectively met during the predicted load occurrence period.For easily adjustable load areas, the cooling capacity arrival marker indicates that cooling capacity can arrive in a timely manner and that the cooling capacity transfer capability meets the cooling demand. For transfer-limited load areas, the cooling capacity arrival marker indicates that there is a delay in cooling capacity arrival, insufficient cooling capacity transfer intensity, or a high degree of transfer attenuation. For insufficient cooling capacity arrival areas, the cooling capacity arrival marker indicates that the corresponding air conditioning zone has an abnormal cooling capacity transfer link or insufficient cooling capacity. The adjustment priority marker is used to determine the processing order of different air conditioning zones in subsequent energy-saving scheduling. For air conditioning zones whose indoor temperature has deviated from the comfort setting range and are marked as insufficient cooling capacity arrival areas, they are identified as high-priority processing objects to prioritize the correction of the cooling capacity transfer path corresponding to the air conditioning zone. For air conditioning zones whose predicted load occurrence period is approaching and are marked as transfer-limited load areas, they are identified as high-priority processing objects so that the corresponding scheduling action can achieve effective cooling capacity arrival before or during the predicted load occurrence period. For air conditioning zones marked as easily adjustable load areas, their priority is determined based on the predicted cooling load demand and the area's cold storage capacity. Cooling method marker. This is used to characterize the cooling treatment method adapted to the corresponding air conditioning zone; for areas with easily adjustable loads, the cooling method is marked as immediate cooling, smooth cooling, or advance cooling; when the area's cold storage capacity meets the advance cooling requirement, the cooling method is marked as advance cooling, so that the corresponding air conditioning zone can achieve a temperature improvement state before the predicted load occurrence period arrives; when the predicted load occurrence period is close to the current scheduling time and the action arrival time meets the immediate response requirement, the cooling method is marked as immediate cooling; for areas with limited load transmission, the cooling method is marked as advance cooling or combined cooling, so as to meet the predicted cooling load demand by issuing control actions in advance or combining multiple control actions; for areas with insufficient cooling capacity, the cooling method is marked as transmission path correction, so as to prioritize the use of water network-side scheduling actions or terminal-side scheduling actions to improve the cooling capacity arrival state; the short-cycle cooling load prediction result is combined with the area cooling capacity transmission core to form the transmission core corrected prediction load result. The transmission core corrected prediction load result retains the predicted cooling load demand and the predicted load occurrence period, and adds cooling capacity arrival capacity markings, adjustment priority markings, and cooling method markings.

[0029] The present invention is further configured such that S7 includes: For each candidate scheduling action in the preset candidate scheduling action set, the regional cooling transfer core corresponding to the target air conditioning zone is called to determine the action arrival time, cooling transfer intensity and transfer attenuation degree when the candidate scheduling action is applied to the target air conditioning zone. Based on the arrival time of the action, the intensity of cold energy transfer, and the degree of transfer attenuation, determine the effective cold energy contribution of the candidate scheduling action in the target air conditioning zone; based on the difference in equipment energy consumption before and after the execution of the candidate scheduling action, determine the change in action energy consumption corresponding to the candidate scheduling action; based on whether the equipment control quantity after the execution of the candidate scheduling action exceeds the equipment operating boundary, determine the equipment operating boundary satisfaction status; based on whether the expected indoor temperature of the target air conditioning zone after the execution of the candidate scheduling action exceeds the comfort setting range, determine the comfort risk status. The candidate scheduling actions, target air conditioning zones, action arrival times, effective cooling contribution, action energy consumption changes, equipment operating boundary satisfaction status, and comfort risk status are correlated to generate a candidate scheduling action effective contribution table. Specifically, the generation process of the candidate scheduling action effective contribution table is used to evaluate the actual effect of different candidate scheduling actions on the target air conditioning zones based on the regional cooling transfer kernel. The generation process uses the action arrival time, cooling transfer intensity, and transfer attenuation degree in the regional cooling transfer kernel as the basis to determine the effective cooling contribution formed in the target air conditioning zone after the execution of the candidate scheduling action. Combined with the action energy consumption changes, equipment operating boundary satisfaction status, and comfort risk status corresponding to the candidate scheduling action, a candidate list for subsequent scheduling action screening is formed. Effective contribution table of scheduling actions; when establishing a set of candidate scheduling actions, control actions that meet the scheduling conditions are determined based on the current equipment composition, equipment operating status, air conditioning zone cooling paths, and adjustable control range of the building air conditioning system; the candidate scheduling actions include at least one of the following: adjusting chiller unit load, switching chiller unit operating combinations, adjusting chilled water supply temperature, adjusting chilled water pump frequency, adjusting branch valve opening, adjusting terminal coil valve opening, adjusting supply air temperature, and adjusting supply air volume; the candidate scheduling actions cover the main unit side, water network side, and terminal side; the main unit side scheduling actions are used to change the overall cooling capacity supply of the building air conditioning system; the water network side scheduling actions are used to change the cooling capacity transported in the chilled water network; the terminal side... Scheduling actions are used to change the heat exchange capacity and air supply effect of cooling capacity near the target air conditioning zone. When the target air conditioning zone is cooled by a single branch and a single terminal device, the regional cooling capacity transfer core corresponding to that branch, that terminal device, and the target air conditioning zone is invoked. When the target air conditioning zone is served by multiple terminal devices or is affected by multiple adjustable air conditioning control variables, multiple regional cooling capacity transfer cores related to the target air conditioning zone are invoked. The corresponding regional cooling capacity transfer core is matched according to the device object, branch affiliation, and control variable type of the candidate scheduling action, so that the evaluation result of the candidate scheduling action characterizes the actual cooling capacity arrival characteristics of the target air conditioning zone. For each candidate scheduling action, the regional cooling capacity transfer core corresponding to the target air conditioning zone is invoked to determine the candidate scheduling action. The arrival time of the action when it is applied to the target air conditioning zone; the arrival time of the action is used to characterize the time required for the cooling effect to be transmitted to the target air conditioning zone via the host side, water network side and terminal side after the candidate scheduling action is issued, and to form an identifiable area-side response; the arrival time of the action is used to determine whether the candidate scheduling action can match the predicted load occurrence period of the target air conditioning zone; then the cooling transfer intensity when the candidate scheduling action is applied to the target air conditioning zone is determined; the cooling transfer intensity is derived from the area cooling transfer core corresponding to the target air conditioning zone, and is used to characterize the ability of the candidate scheduling action to form an effective temperature improvement in the target air conditioning zone; when the cooling transfer intensity is high, it indicates that the candidate scheduling action can effectively improve the cooling arrival state of the target air conditioning zone;When the cold energy transfer intensity is low, it indicates that the candidate scheduling action is unlikely to contribute effective cold energy. The degree of transfer attenuation corresponding to the candidate scheduling action is then determined; this attenuation characterizes the weakening of the response as the cold energy change caused by the candidate scheduling action is transmitted along the main unit side, water network side, terminal side, and regional side. The actual cold energy delivery capability of the candidate scheduling action is evaluated by combining the action arrival time, cold energy transfer intensity, and transfer attenuation. When determining the effective cold energy contribution, the initial cold energy contribution is determined based on the action adjustment amplitude of the candidate scheduling action and the cold energy transfer intensity in the corresponding regional cold energy transfer core. The initial cold energy contribution is then reduced based on the transfer attenuation in the corresponding regional cold energy transfer core to obtain the arriving cold energy contribution. Based on the candidate scheduling action's... The matching relationship between the arrival time of an action and the predicted load occurrence period of the target air conditioning zone is used to correct the arrival cooling contribution. Specifically, if the arrival time of the action allows the cooling effect of the candidate scheduling action to reach the target air conditioning zone within the predicted load occurrence period, the arrival cooling contribution is retained. If the arrival time of the action causes the cooling effect to arrive at the target air conditioning zone later than the predicted load occurrence period, the arrival cooling contribution is reduced, thus obtaining the effective cooling contribution formed by the candidate scheduling action in the target air conditioning zone. The effective cooling contribution characterizes the cooling improvement capability formed by the candidate scheduling action in the target air conditioning zone after passing through the actual cooling transfer path. When determining the change in energy consumption of the action, the difference in equipment energy consumption before and after the execution of the candidate scheduling action is compared. The energy consumption difference before the execution of the candidate scheduling action is... Equipment energy consumption is determined based on the current operating state or baseline operating state; the equipment energy consumption after the execution of a candidate scheduling action is determined based on the target control parameters, equipment operating characteristics, and current load conditions; when the candidate scheduling action is to increase the chiller unit load, the change in action energy consumption is characterized by the change in chiller unit power; when the candidate scheduling action is to adjust the chilled water pump frequency, the change in action energy consumption is characterized by the change in chilled water pump power; when the candidate scheduling action is to adjust the air supply volume, the change in action energy consumption is characterized by the change in terminal fan power; when the candidate scheduling action is to adjust the valve opening, the change in action energy consumption is jointly characterized by the pump delivery status and branch flow changes; when determining that the equipment operating boundary meets the state, it is judged whether the equipment control quantity after the execution of the candidate scheduling action is within the corresponding allowable range. Within the equipment operating boundary; the equipment operating boundary includes the allowable load range of the chiller unit, the allowable set range of the chilled water supply temperature, the allowable range of the chilled water pump frequency, the allowable range of the branch valve opening, the allowable range of the terminal coil valve opening, the allowable range of the supply air temperature, and the allowable range of the supply air volume; if the equipment control quantity after the candidate scheduling action is executed is within the allowable operating boundary and does not trigger equipment protection, protection interlock, or start / stop restrictions, then the equipment operating boundary satisfaction state is determined to be satisfied; the equipment operating boundary satisfaction state is used to avoid generating scheduling actions that are unexecutable or pose safety risks; when determining the comfort risk state, the indoor temperature change trend after the candidate scheduling action is executed is estimated based on the current indoor temperature and temperature change rate of the target air conditioning zone;When a candidate scheduling action enhances cooling, it is determined whether the expected indoor temperature is below the lower limit of the comfort setting range; when a candidate scheduling action weakens cooling, it is determined whether the expected indoor temperature is above the upper limit of the comfort setting range; if the expected indoor temperature remains within the comfort setting range, the comfort risk state is determined to be risk-free; if the expected indoor temperature exceeds the comfort setting range, the comfort risk state is determined to be risky; when generating the effective contribution table of candidate scheduling actions, the candidate scheduling action, target air conditioning zone, action arrival time, effective cooling contribution, action energy consumption change, equipment operating boundary satisfaction status, and comfort risk state are associated and stored; the candidate... The selected scheduling action is used to identify the control action type and the controlled object; the target air conditioning zone is used to identify the area of ​​effect of the candidate scheduling action; the action arrival time is used to characterize the time required for the candidate scheduling action to reach the target air conditioning zone; the effective cooling capacity contribution is used to characterize the actual cooling capacity improvement capability of the candidate scheduling action on the target air conditioning zone; the action energy consumption change is used to characterize the energy consumption change generated by executing the candidate scheduling action; the equipment operating boundary satisfaction status is used to characterize whether the candidate scheduling action meets the equipment's allowed operating conditions; the comfort risk status is used to characterize whether the candidate scheduling action poses a risk of causing the target air conditioning zone to exceed the comfort setting range.

[0030] The present invention is further configured such that S8 includes: The scheduling order of each air conditioning zone is determined according to the adjustment priority mark; according to the scheduling order, for each air conditioning zone, candidate scheduling actions that meet the equipment operation boundary and have no comfort risk are selected from the effective contribution table of candidate scheduling actions as safety candidate actions. When the effective cooling capacity contribution of a single safety candidate action meets the predicted cooling load demand of the air conditioning zone, the corresponding safety candidate action is determined as an available scheduling action; when the effective cooling capacity contribution of multiple safety candidate actions meets the predicted cooling load demand of the air conditioning zone, the safety candidate action with the lower energy consumption change is selected as an available scheduling action; when the effective cooling capacity contribution of a single safety candidate action is insufficient to meet the predicted cooling load demand, multiple safety candidate actions are selected to form an available scheduling action combination. The control command issuance time is determined based on the arrival time of the selected available scheduling actions and the predicted load occurrence period of the corresponding air conditioning zone; Based on the selected available scheduling actions, control command issuance time, control command duration, and target air conditioning zones, a building air conditioning energy-saving scheduling scheme is generated. The invention further specifies that the control command duration is determined based on the predicted load occurrence period of the corresponding air conditioning zone and the action type of the selected available scheduling actions. Specifically, when determining the scheduling order of each air conditioning zone, the adjustment priority flag in the predicted load result after kernel correction is obtained to indicate the urgency of processing for different air conditioning zones within the current scheduling cycle. When processing each air conditioning zone according to the scheduling order, candidate scheduling actions with the equipment operating boundary satisfying state and the comfort risk state being risk-free are selected from the candidate scheduling action effective contribution table, and the selected candidate scheduling actions are then... Actions are identified as safety candidate actions. The selection of safety candidate actions ensures that the subsequently generated building air conditioning energy-saving scheduling scheme meets engineering feasibility requirements and comfort safety boundary requirements. After identifying safety candidate actions, the effective cooling capacity contribution of a single safety candidate action is matched with the predicted cooling load demand of the corresponding air conditioning zone. When the effective cooling capacity contribution of a single safety candidate action can meet the predicted cooling load demand of the corresponding air conditioning zone during the predicted load period, the safety candidate action is identified as an available scheduling action. An available scheduling action indicates that the corresponding air conditioning zone can meet its cooling demand through a single safety candidate action without the need for additional scheduling actions. When multiple safety candidate actions have effective cooling capacity contributions that can meet the predicted cooling load demand of the corresponding air conditioning zone during the predicted load period, the action is considered a usable scheduling action. When the predicted cooling load demand of the corresponding air conditioning zone is sufficient, the energy consumption changes of each safety candidate action relative to the baseline operating state are compared, and the safety candidate action with the lower energy consumption change is determined as the available scheduling action; when the effective cooling capacity contribution of any single safety candidate action is insufficient to meet the predicted cooling load demand of the corresponding air conditioning zone, multiple scheduling actions with the same direction of action, the same target air conditioning zone, or coordinated cooling capacity transfer paths are selected from the safety candidate actions to form a combination of available scheduling actions; the effective cooling capacity contribution of the combination of available scheduling actions should cover the predicted cooling load demand of the corresponding air conditioning zone, and the combined equipment operating boundary should meet the scheduling requirements of the state and comfort risk state; when determining the control command issuance time. The starting time of the predicted load occurrence period for the corresponding air conditioning zone is taken as the target arrival time of the cooling capacity. Based on the arrival time of the selected available scheduling action or combination of available scheduling actions, the basic lead time required for the cooling capacity to reach the target air conditioning zone from the issuance of the control command is determined. When the selected available scheduling action is a host-side scheduling action or a water network-side scheduling action, the target air conditioning zone is reached after passing through the host-side output, water network-side transmission, and terminal-side heat exchange, based on the fact that the cooling capacity needs to pass through the host-side output, water network-side transmission, and terminal-side heat exchange. The response reservation time is added to the basic lead time to obtain the target lead time. When the selected available scheduling action is a terminal-side scheduling action, the basic lead time is determined as the target lead time. The target arrival time of the cooling capacity is shifted forward by the target lead time to obtain the control command issuance time.If the control command issuance time is earlier than the current executable scheduling time, the current executable scheduling time is determined as the control command issuance time. The duration of the control command is determined based on the predicted load occurrence period of the corresponding air conditioning zone and the action type of the selected available scheduling action. The duration of the predicted load occurrence period is used as the basis for the duration. When the selected available scheduling action is a terminal-side scheduling action, the duration of the predicted load occurrence period is determined as the control command duration. When the selected available scheduling action is a water network-side scheduling action, the sum of the duration of the predicted load occurrence period and the preset water network transmission compensation duration is determined as the control command duration. When the selected available scheduling action is a host-side scheduling action, the duration of the predicted load occurrence period is compared with the preset host stable maintenance duration, and the longer of the two is determined as the control command duration to avoid frequent start-stop or frequent large-scale adjustments on the host side. When implementing a building air conditioning energy-saving scheduling scheme, the selected available scheduling actions or combinations of available scheduling actions, the control command issuance time, the control command duration, and the target air conditioning zone are associated and converted into equipment target control parameters. When the available scheduling action is adjusting the chilled water pump frequency, the equipment target control parameter is the target frequency of the corresponding chilled water pump; when the available scheduling action is adjusting the branch valve opening, the equipment target control parameter is the target opening of the corresponding branch valve; when the available scheduling action is adjusting the terminal coil valve opening, the equipment target control parameter is the target opening of the corresponding terminal coil valve; when the available scheduling action is adjusting the supply air temperature or supply air volume, the equipment target control parameter is the target supply air temperature or target supply air volume of the corresponding terminal equipment; when the available scheduling action is adjusting the chiller unit load or switching the chiller unit operating combination, the equipment target control parameter is the target load state or target operating combination of the corresponding chiller unit.

Based on the matching relationship between the predicted cooling load demand and the cooling intensity, attenuation degree and cold storage capacity of the corresponding area's cooling core, the cooling capacity of the corresponding air conditioning zone is determined to be in a suitable state. Based on the cooling capacity response time status and the cooling capacity reaching the adaptation status, the corresponding air conditioning zones are marked as easily adjustable load areas or load transfer restricted areas. When the predicted cooling load demand of the corresponding air conditioning zone is lower than the preset load threshold, and the indoor temperature of the air conditioning zone deviates from the comfort setting range within a preset duration, and the cooling transfer intensity in the corresponding area's cooling transfer core is lower than the preset transfer intensity threshold or the transfer attenuation degree is higher than the preset attenuation threshold, the air conditioning zone is marked as an area with insufficient cooling capacity. Based on the easily adjustable load areas, the load areas with limited transmission, and the areas with insufficient cooling capacity, the short-cycle cooling load forecast results for each air conditioning zone are augmented with cooling capacity arrival capacity markers, adjustment priority markers, and cooling mode markers to generate the predicted load results after transmission core correction.

The method for predicting and energy-saving scheduling of building air conditioning load according to claim 6, characterized in that, S7 includes: For each candidate scheduling action in the preset candidate scheduling action set, the regional cooling transfer core corresponding to the target air conditioning zone is called to determine the action arrival time, cooling transfer intensity and transfer attenuation degree when the candidate scheduling action is applied to the target air conditioning zone. Based on the arrival time of the action, the intensity of cold energy transfer, and the degree of transfer attenuation, determine the effective cold energy contribution of the candidate scheduling action in the target air conditioning zone; based on the difference in equipment energy consumption before and after the execution of the candidate scheduling action, determine the change in action energy consumption corresponding to the candidate scheduling action; based on whether the equipment control quantity after the execution of the candidate scheduling action exceeds the equipment operating boundary, determine the equipment operating boundary satisfaction status; based on whether the expected indoor temperature of the target air conditioning zone after the execution of the candidate scheduling action exceeds the comfort setting range, determine the comfort risk status. The candidate scheduling actions, target air conditioning zones, action arrival time, effective cooling capacity contribution, action energy consumption changes, equipment operating boundary satisfaction status, and comfort risk status are correlated to generate an effective contribution table for candidate scheduling actions.

9. The method for predicting and energy-saving scheduling of building air conditioning load according to claim 1, characterized in that, S8 includes: The scheduling order of each air conditioning zone is determined according to the adjustment priority mark; according to the scheduling order, for each air conditioning zone, candidate scheduling actions that meet the equipment operation boundary and have no comfort risk are selected from the effective contribution table of candidate scheduling actions as safety candidate actions. When the effective cooling capacity contribution of a single safety candidate action meets the predicted cooling load demand of the air conditioning zone, the corresponding safety candidate action is determined as an available scheduling action; when the effective cooling capacity contribution of multiple safety candidate actions meets the predicted cooling load demand of the air conditioning zone, the safety candidate action with the lower energy consumption change is selected as an available scheduling action; when the effective cooling capacity contribution of a single safety candidate action is insufficient to meet the predicted cooling load demand, multiple safety candidate actions are selected to form an available scheduling action combination. The control command issuance time is determined based on the arrival time of the selected available scheduling actions and the predicted load occurrence period of the corresponding air conditioning zone; Based on the selected available scheduling actions, control command issuance time, control command duration, and target air conditioning zone, a building air conditioning energy-saving scheduling scheme is generated.
