Description

Technical Field

[0001] The present application relates to the field of air conditioning technology, and in particular to a method, device, computer equipment, and storage medium for determining an air conditioning potential curve. Background Art

[0002] Under the dual carbon goals, the construction of a new power system requires more flexible load regulation capabilities on the user side to increase renewable energy consumption and enhance power system stability. As a major end-user of electricity, buildings bear greater regulatory responsibility. Considering the flexible regulation capabilities of building electrical energy equipment, air conditioning systems, leveraging the thermal storage capacity of indoor spaces, have considerable potential for regulation.

[0003] Traditionally, building air conditioning systems operate continuously for nearly ten hours a day during the cooling and heating seasons, consuming 50% to 80% of electricity. Broader indoor comfort requirements require that air conditioning systems be able to maintain thermal comfort while allowing for fluctuations in cooling and heating within a certain range. Therefore, flexible air conditioning system regulation is a key method for achieving building-grid interaction and user-side peak load regulation. The air conditioning potential curve is designed to characterize the extent and duration of the change in the air conditioning system's operating power after regulation relative to the baseline power (pre-regulation power), while ensuring user comfort and the safety and stability of the air conditioning equipment.

[0056] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0057] The method for determining the air conditioning potential curve provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown, terminal 102 communicates with server 104 via a network. A data storage system can store data that server 104 needs to process. The data storage system can be integrated with server 104, or located on a cloud or other network server. Before the air conditioner is temperature-adjusted, the computer device obtains the air conditioner's initial operating power. For each temperature adjustment process, the computer device obtains the target operating power of the air conditioner at a target time after the temperature adjustment process. The target time is the time when the indoor temperature of the air conditioner reaches a preset temperature threshold after the temperature adjustment process. A potential curve for the air conditioner is determined based on the air conditioner's initial operating power, the target time corresponding to each temperature adjustment process, and the target operating power. The potential curve represents the degree and duration of change in the air conditioner's operating power relative to the initial operating power during the temperature adjustment process. The computer device can be either a terminal or a server. Terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can include smart speakers, smart TVs, smart air conditioners, smart car devices, etc. Portable wearable devices can include smart watches, smart bracelets, head-mounted devices, etc. The server 104 may be implemented as an independent server or a server cluster consisting of multiple servers.

[0058] In an exemplary embodiment, Figure 2A As shown, a method for determining an air conditioning potential curve is provided, and the method is applied to Figure 1 The computer device in the example is used to illustrate, including the following steps S201 to S203.

[0059] S201 : Obtaining the initial operating power of the air conditioner without adjusting the temperature of the air conditioner.

[0060] Specifically, based on the air conditioning system's historical operating power data, the system's operating load rate range (i.e., the upper and lower limits of the air conditioning system's operating load rate) was determined. Based on the building's operating indoor temperature range, the building's indoor comfort level range (i.e., the range of indoor temperature variation) was determined during air conditioning operation. A specific air conditioning load rate (e.g., 90%, 80%, 70%, and 60%) was selected as a test condition. For each load rate test condition, the initial operating power of the air conditioner was obtained without temperature adjustment.

[0061] For example, the indoor temperature baseline is 26°C, the lower limit of the indoor temperature variation is 24°C, and the upper limit of the indoor temperature is 28°C. Under a certain air conditioning load rate test condition, set the air conditioning chilled water supply temperature to 7°C and the indoor air conditioning temperature to 26°C. The system is run for a period of time. When the chiller operating power does not change by more than 5% within 5 minutes, the air conditioning system is considered to have reached a stable operating state, meaning that the chiller cooling capacity is balanced with the building's cooling load demand. Record the air conditioning chiller unit operating power P0.

[0062] S202 , for each temperature adjustment process of the air conditioner, obtaining a target operating power of the air conditioner at a target time after the temperature adjustment process.

[0063] The target time is the time when the indoor temperature of the air conditioner reaches the preset temperature threshold after the air conditioner is temperature-adjusted. The temperature adjustment process includes temperature-raising process and temperature-lowering process.

[0064] Specifically, for each temperature adjustment process of the air conditioner, if the temperature adjustment process is a temperature increase process, the target operating power of the air conditioner at the target time after the temperature increase process is obtained. If the temperature adjustment process is a temperature decrease process, the target operating power of the air conditioner at the target time after the temperature decrease process is obtained.

[0065] S203 , determining a potential curve of the air conditioner according to the initial operating power of the air conditioner, the target time corresponding to each temperature adjustment process, and the target operating power.

[0066] The potential curve represents the degree and duration of change in the air conditioner's operating power relative to the initial operating power during the temperature adjustment process. The potential curve includes an upward potential curve and a downward potential curve.

[0067] One optional implementation method is to input the initial operating power of the air conditioner, the target time and target operating power corresponding to each temperature adjustment process into the potential curve determination model through a pre-trained potential curve determination model to obtain the potential curve of the air conditioner.

[0068] Another optional implementation method is to determine the air conditioner's upward adjustment potential curve based on the air conditioner's initial operating power, the air conditioner's target time and target operating power after each temperature reduction process; and to determine the air conditioner's downward adjustment potential curve based on the air conditioner's initial operating power, the air conditioner's target time and target operating power after each temperature increase process.

[0069] Specifically, the air conditioner's initial operating power, the target time of each temperature reduction, and the target operating power are input into a pre-trained model for determining the potential curve for upward adjustment to obtain the air conditioner's potential curve for upward adjustment. The air conditioner's initial operating power, the target time of each temperature increase, and the target operating power are input into a pre-trained model for determining the potential curve for downward adjustment to obtain the air conditioner's potential curve for downward adjustment.

[0070] It should be noted that the adjustable potential of air conditioners is affected by two aspects of boundary conditions, including user comfort boundary conditions and air conditioner operation boundary conditions. User comfort boundary conditions determine the duration of adjustment. Under the same temperature adjustment range, buildings with different cold and heat storage capacities will have different adjustment durations. The air conditioner operation boundary conditions are the upper and lower limits of the air conditioner operating power. The upper limit is the rated power of the unit (load rate 100%), and the lower limit is the minimum operating power allowed by the unit (load rate lower limit, generally 25%). As follows Figure 2B The schematic diagram of the boundary condition of air conditioning adjustable potential is shown. Air conditioning adjustable potential is a dynamically changing parameter that changes with the thermal storage performance of the building envelope and the operating load rate of the air conditioning system.

[0071] The above-mentioned air conditioner potential curve determination method, apparatus, computer equipment, and storage medium obtain the initial operating power of the air conditioner without temperature adjustment. For each temperature adjustment process of the air conditioner, the target operating power of the air conditioner at the target time after the temperature adjustment process is obtained. The target time is the time when the indoor temperature of the air conditioner reaches a preset temperature threshold after the temperature adjustment process. The air conditioner potential curve is determined based on the initial operating power of the air conditioner, the target time corresponding to each temperature adjustment process, and the target operating power. The potential curve represents the degree and duration of change in the air conditioner operating power relative to the initial operating power during the temperature adjustment process of the air conditioner. This embodiment can clearly define the two evaluation dimensions of the adjustable potential of the air conditioner: the adjustment depth and duration. It also proposes two boundary conditions: user comfort boundary conditions and air conditioner operation boundary conditions, thereby more accurately determining the air conditioner potential curve. At the same time, this embodiment does not rely on complex methods such as load forecasting and multi-parameter fusion that require high computing power, resulting in stronger engineering feasibility and lower industrialization costs.

[0072] Figure 3A This is a flow chart illustrating the steps for determining a potential-downward adjustment curve in one embodiment. This embodiment refines the steps for determining an air conditioner's potential-downward adjustment curve based on the air conditioner's initial operating power, the target time of the air conditioner after each temperature increase, and the target operating power in the above embodiment. This embodiment provides an optional method for determining the potential-downward adjustment curve, including the following steps:

[0073] S301, determining a reference time for the air conditioner.

[0074] The reference time is the time when the indoor temperature of the room where the air conditioner is located changes.

[0075] One of the optional implementation methods is to directly obtain the reference time preset by the air conditioner.

[0076] Another optional implementation method is to determine a first time preset for the air conditioner; for each temperature increase process, determine a second time at which the indoor temperature of the room where the air conditioner is located changes after the temperature increase process; and determine a reference time preset for the air conditioner based on the first time and each second time. The first time is the time at which the return water temperature of the air conditioner changes after the temperature increase process is performed on the air conditioner.

[0077] Specifically, after the air conditioner is subjected to temperature increase processing, the moment when the return water temperature of the air conditioner changes is obtained as the first moment; for each temperature increase processing, the second moment when the indoor temperature of the room where the air conditioner is located changes after the temperature increase processing is determined; based on the pre-set reference moment determination model, the preset reference moment of the air conditioner is determined according to the first moment and the second moment.

[0078] Specifically, the implementation method of determining the reference time preset for the air conditioner based on the first moment and each second moment is as follows: for each temperature increase processing, determine the time difference between the second moment corresponding to this temperature increase processing and the first moment; use the average value of the difference between each moment and the sum of the values between the first moment as the reference moment.

[0079] For example, when the air conditioning system is operating stably, the chiller's operating power can be reduced by adjusting the chilled water supply temperature. The chilled water supply temperature is set to 8°C, and the chilled water return temperature change time Ta1 and the indoor temperature change time Tb1 are recorded. The chilled water supply temperature is then reset to 7°C. Once the air conditioning system enters a stable operating state, the chilled water supply temperature is set again to 12°C, and the chilled water return temperature change time Ta2 and the indoor temperature change time Tb2 are recorded. Based on the chilled water return temperature change time Ta1, the indoor temperature change time Tb1, the chilled water return temperature change time Ta2, and the indoor temperature change time Tb2, the following formula (1-1) is used to determine the indoor airflow distribution and the impact of internal and external disturbances, thereby obtaining a reference time.

[0080] Tb=[(Tb1-Ta)+(Tb2-Ta)]\2+Ta (1-1)

[0081] Where Tb represents the reference time; Tb1 represents the second time when the air conditioner's chilled water supply temperature is set to 8°C; Tb2 represents the second time when the air conditioner's chilled water supply temperature is set to 12°C; Ta1 represents the first time when the air conditioner's chilled water supply temperature is set to 8°C; and Ta2 represents the first time when the air conditioner's chilled water supply temperature is set to 12°C. Due to the influence of the air conditioner system's chilled water circulation speed, Ta1 = Ta2 = Ta.

[0082] S302, for each temperature increase processing, the difference between the initial operating power and the target motion power after this temperature increase processing is used as the downward power value after this temperature increase processing; and the difference between the target moment after this temperature increase processing and the reference moment is used as the temperature change time difference after this temperature increase processing.

[0083] For example, using the first temperature increase process as an example, while the air conditioning system is operating stably, the chiller's operating power is reduced by adjusting the chiller's chilled water supply temperature. The chiller's chilled water supply temperature is set to 8°C, and the unit's operating power, P1, is recorded. The difference between the initial operating power, P0, and the target operating power, P1, after this temperature increase is used as the power reduction value after this temperature increase (i.e., ΔP1 = P0 - P1). The difference between the target time, Tc1, after this temperature increase, and the reference time, Tb, is used as the temperature change time difference after this temperature increase (i.e., ΔT = Tc1 - Tb).

[0084] S303 , determining a downward adjustment potential curve of the air conditioner according to a correlation between the downward adjustment power value after each temperature increase process and the temperature change time difference after the corresponding temperature increase process.

[0085] Specifically, a downward adjustment potential curve of the air conditioner is constructed according to the correlation between the downward adjustment power value after each temperature increase process and the temperature change time difference after the corresponding temperature increase process.

[0086] For example, Figure 3B The diagram of the potential down-regulation curve, shown here, uses two examples of temperature increases. This is influenced by the building's thermal mass, Q, where ΔP1 × (Tc1 - Tb1) = ΔP2 × (Tc2 - Tb2) = Q. Therefore, any point on the potential down-regulation curve for air conditioning can be expressed as: ΔPx × (Tcx - Tb) = Q.

[0087] It should be noted that by selecting different operating load rates as test conditions and repeating the steps of the above embodiment, the air conditioner adjustable potential curves under different operating load rates can be obtained.

[0088] It should be noted that the construction method of the air conditioner's upward adjustment potential curve is the same as that of the air conditioner's downward adjustment potential curve. It is only necessary to change the temperature increase process to the temperature decrease process, such as setting the air conditioner's chilled water supply temperature to 6 degrees and 4 degrees respectively, and record the moment when the indoor temperature reaches the lower limit (24 degrees).

[0089] In this embodiment, the method for constructing the air conditioning adjustable potential curve only uses the existing monitoring data of the building air conditioning system, including the operating power of the air conditioning unit, the chilled water supply temperature, the chilled water return temperature and the indoor temperature measurement points. This method does not require additional measurement points and is simple and easy to operate.

[0090] Figure 4A The flowchart of the steps for determining air conditioning potential points in one embodiment includes the following steps:

[0091] S401: For any coordinate point on the potential curve, determine the horizontal coordinate and vertical coordinate corresponding to the coordinate point.

[0092] The ordinate represents the degree of change of the air conditioner operating power relative to the initial operating power; the abscissa represents the duration of time the air conditioner remains stable at the regulated temperature corresponding to the corresponding air conditioner operating power.

[0093] For example, Figure 4BThe following diagram shows an air conditioning adjustment potential curve. The air conditioning adjustment potential curve describes the degree and duration of change in the air conditioning system's operating power after adjustment relative to the baseline power (pre-adjustment operating power), while ensuring user comfort and the safety and stability of the air conditioning equipment. The baseline power refers to the operating power of the air conditioner unit to meet indoor comfort requirements before the adjustment. The power adjustment depth refers to the degree of change in the operating power relative to the baseline power; the adjustment duration refers to the duration during which the operating power remains stable at the target adjustment value. Therefore, for any coordinate point on the potential curve, it is possible to determine the stability of the indoor thermal environment maintained by the air conditioner at the corresponding adjustment temperature. Therefore, to find the optimal adjustment temperature for the air conditioner, the corresponding horizontal and vertical coordinates are determined.

[0094] S402: The product value between the horizontal coordinate and the vertical coordinate is used as the adjustment capacity of the air conditioner.

[0095] Specifically, the product value between the abscissa and the ordinate is determined; and the product value is used as the adjustment capacity of the air conditioner.

[0096] S403: Select the coordinate point with the largest adjustment capacity as the air conditioning potential point.

[0097] Among them, the air-conditioning potential point represents the air-conditioning's optimal performance in maintaining the stability of the indoor thermal environment at the adjustment temperature corresponding to the air-conditioning potential point.

[0098] In this embodiment, for any coordinate point on the potential curve, the horizontal and vertical coordinates corresponding to the coordinate point are determined, and the product value between the horizontal and vertical coordinates is used as the adjustment capacity of the air conditioner; the coordinate point with the largest adjustment capacity is selected as the air conditioner potential point, which can more accurately determine the air conditioner potential point.

[0099] In one embodiment, this embodiment provides an optional method for determining the potential curve for downward adjustment, and takes the application of this method to a server as an example for explanation. Figure 5 As shown, the method includes the following steps:

[0100] S501: Obtaining the initial operating power of the air conditioner without adjusting the temperature of the air conditioner.

[0101] S502 , for each temperature adjustment process of the air conditioner, obtaining a target operating power of the air conditioner at a target time after the temperature adjustment process.

[0102] The target time is the time when the indoor temperature of the air conditioner reaches a preset temperature threshold after the air conditioner is temperature-adjusted.

[0103] S503, determining the first preset moment of the air conditioner.

[0104] The first moment is the moment when the return water temperature of the air conditioner changes after the temperature of the air conditioner is increased.

[0105] S504: For each temperature increasing process, determine a second time when the indoor temperature of the room where the air conditioner is located changes after the temperature increasing process.

[0106] S505 , for each temperature raising process, determining a time difference between the second time corresponding to the current temperature raising process and the first time.

[0107] S506: The sum of the average value of the differences at each moment and the first moment is used as a reference moment.

[0108] The reference time is the time when the indoor temperature of the room where the air conditioner is located changes.

[0109] S507, for each temperature increase processing, the difference between the initial operating power and the target motion power after this temperature increase processing is used as the downward power value after this temperature increase processing; and the difference between the target moment after this temperature increase processing and the reference moment is used as the temperature change time difference after this temperature increase processing.

[0110] S508 , determining a downward adjustment potential curve of the air conditioner according to a correlation between the downward adjustment power value after each temperature increase process and the temperature change time difference after the corresponding temperature increase process.

[0111] The potential curve represents the degree of change and duration of the air conditioner operating power relative to the initial operating power during the temperature adjustment process of the air conditioner.
