Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment control technology, specifically to a variable frequency dehumidifier collaborative control system integrating intelligent ventilation. Background Technology

[0002] Variable frequency dehumidifiers typically form a cooling and dehumidification circuit through a compressor, an indoor fan, an outdoor fan, and an electronic expansion valve. They adjust the compressor frequency, fan speed, and electronic expansion valve opening according to the indoor temperature and humidity deviation. Variable frequency dehumidifiers with integrated ventilation functions can also perform fresh air introduction or indoor exhaust through ventilation fans and ventilation valves.

[0003] Existing variable frequency dehumidifiers with integrated ventilation functions typically divide cooling, dehumidification, ventilation, and protection operations into multiple operating modes. The current mode is selected based on a fixed priority and triggering conditions, and control commands are sent to the compressor, electronic expansion valve, indoor and outdoor fans, ventilation fan, and ventilation valve according to the current mode. This method can complete temperature and humidity regulation or air exchange when a single demand is continuous and the equipment operating status changes little.

[0004] The limitations of existing technologies include at least the following problems: When air quality requirements, temperature and humidity control requirements, external mandatory commands, and equipment protection commands are superimposed one after another, the controller usually directly overwrites the original control output according to the new mode. However, the position of the air valve, the operating status of the fan, the compressor frequency, and the opening degree of the electronic expansion valve all have a holding process and a migration delay. The airflow path and refrigerant circulation state formed by the previous mode are easily carried into the next mode, and repeated switching occurs near the demand determination boundary. The root cause is that the mode arbitration only applies to the current demand result and does not uniformly constrain the current state, target state, and migration sequence of each execution component. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a variable frequency dehumidifier collaborative control system with integrated intelligent ventilation. This system is used to solve the problem that when multiple operational demands overlap and equipment protection intervenes, the discrete mode switching and the continuous state transition of each actuator become misaligned, resulting in difficulties in coordinating and connecting the airflow path, refrigeration and dehumidification circuit, and ventilation execution state.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated intelligent ventilation variable frequency dehumidifier collaborative control system, comprising: a demand event generation module, used to acquire air quality demand, temperature and humidity adjustment demand, timed ventilation demand, external forced commands, and equipment protection commands, and generate an operational demand event chain; an operational status generation module, used to collect control parameters, feedback parameters, changes in the previous control command, and command elapsed time of the ventilation execution chain and the refrigeration and dehumidification execution chain, generate a current operational status group, and generate a target operational status group containing target control parameters and equipment operational boundaries based on the operational demand event chain; and an incomplete response parsing module, used to analyze historical operational events... The system generates historical response relationships based on line data, generates incomplete response values ​​based on the change in the previous control command, the duration of the command, and the historical response relationships, and generates upstream incomplete response quantities along the airflow transmission order and the cooling and dehumidification response transmission order; the release condition generation module generates component command release conditions based on upstream incomplete response quantities and the target operating state group; the state transition generation module generates a state transition sequence from the current operating state group to the target operating state group based on the component command release conditions; and the collaborative control module executes the state transition sequence, updates the current operating state group according to feedback parameters, and reconstructs the unexecuted state transition segments when the equipment protection command intervenes.

[0007] Furthermore, the formation process of the operational demand event chain is as follows: air quality demand and temperature and humidity regulation demand are written into demand intensity, occurrence time and duration; timed ventilation demand and external forced commands are written into target parameters, occurrence time and duration to form demand events; equipment protection commands are written into restricted execution components and equipment operating boundaries to form protection events; demand events and protection events are connected according to occurrence time and overlap relationship to generate operational demand event chain.

[0008] Furthermore, the formation process of the current operating state group and the target operating state group is as follows: Compressor frequency, electronic expansion valve opening, internal fan speed, external fan speed, ventilation fan speed, ventilation fan direction, and ventilation valve opening are collected to form a control parameter group; refrigerant pressure, suction temperature, discharge temperature, actual execution feedback of each actuator, and command completion feedback are collected to form a feedback parameter group; the change in the previous control command and the command elapsed time corresponding to each control parameter are extracted; the control parameter group, feedback parameter group, change in the previous control command, and command elapsed time are combined according to the ventilation airflow transmission order and the refrigeration and dehumidification response transmission order to generate the current operating state group; the target control parameters and equipment operating boundaries are determined based on the current valid demand and equipment protection commands in the operating demand event chain to generate the target operating state group.

[0009] Furthermore, the formation process of historical response relationships and incomplete response values ​​is as follows: Extract response segments from historical operating data where the control parameters of a single execution component undergo a step change while the control parameters of other execution components remain within the corresponding fluctuation range; arrange the actual execution feedback and associated feedback parameter changes of the corresponding execution components according to the elapsed time after the control command is issued to generate historical response relationships; substitute the change amount of the previous control command and the command elapsed time into the historical response relationships to generate the predicted response of the previous control command that has not yet been released in the current control cycle; correct the predicted response based on the command completion feedback to generate incomplete response values.

[0010] Furthermore, the formation process of the upstream incomplete response quantity is as follows: The incomplete response values ​​corresponding to the ventilation valve, ventilation fan, and indoor fan are normalized according to their respective maximum complete response amplitude to generate the airflow incomplete response value; the incomplete response values ​​corresponding to the compressor, outdoor fan, and electronic expansion valve are normalized according to their respective maximum complete response amplitude to generate the refrigeration and dehumidification incomplete response value; the upstream actuators corresponding to each actuator to be released are determined according to the airflow transmission order and the refrigeration and dehumidification response transmission order; the response transmission ratio of each upstream actuator is determined according to the historical response relationship, and the corresponding normalization results are weighted and accumulated to generate the airflow upstream response quantity and the refrigeration and dehumidification upstream response quantity; at the evaporator heat exchange correlation position, the airflow side influence coefficient and the refrigerant side influence coefficient are determined according to the airflow side response contribution value and the refrigerant side response contribution value, and the airflow upstream response quantity and the refrigeration and dehumidification upstream response quantity are weighted and synthesized to generate the upstream incomplete response quantity of each actuator to be released.

[0011] Furthermore, the process of forming the component instruction release condition is as follows: Based on the target control parameters, equipment operating boundaries, and historical response relationships in the target operating state group, determine the upstream incomplete response threshold of the corresponding execution component; predict the decay result of the upstream incomplete response quantity with the control cycle based on the historical response relationship; determine the first control cycle in which the decay result is not higher than the upstream incomplete response threshold and the feedback parameter is within the equipment operating boundary; associate the first control cycle, the upstream incomplete response threshold, and the corresponding feedback parameter range with the corresponding execution component to form the component instruction release condition.

[0012] Furthermore, the formation process of the state transition sequence is as follows: the current operating state group is set as the starting state; the corresponding control parameters are maintained until the component instruction release condition is met; after the component instruction release condition is met, the parameter change rate of the corresponding execution component is determined according to the historical response relationship, and the next operating state group is generated within the equipment operating boundary; the upstream unfinished response quantity and component instruction release condition are recalculated based on the next operating state group; the next operating state group is repeatedly generated until the target operating state group is reached, thus forming a state transition sequence.

[0013] Furthermore, the processing procedure when the operational demand event chain changes in reverse is as follows: Collect the actual control parameters and feedback parameters of each execution component when the operational demand event chain changes in reverse, and generate an updated current operational state group; generate an updated target operational state group based on the reversed operational demand event chain; compare the migration direction of each control parameter in the updated current operational state group and the updated target operational state group; retain state migration segments with the same migration direction, set the current actual control parameter with the opposite migration direction as the reverse migration starting point, set the corresponding control parameter that most recently met the component instruction release condition and completed feedback verification as the fallback target parameter, and if no corresponding control parameter exists, set the control parameter corresponding to the initial state as the fallback target parameter; determine the parameter change rate corresponding to the control parameter with the opposite migration direction based on the historical response relationship, generate a reverse migration segment from the reverse migration starting point to the fallback target parameter, and regenerate the state migration sequence to the updated target operational state group starting from the end point of the reverse migration segment.

[0014] Furthermore, the reconstruction process when the equipment protection command intervenes is as follows: extract the restricted execution component and equipment operating boundary corresponding to the equipment protection command from the operation demand event chain; limit the control parameters of the restricted execution component to within the equipment operating boundary, and retain the control parameters of the unrestricted execution component in the current operating state group; update the target operating state group based on the current valid demand in the operation demand event chain, the limited control parameters of the restricted execution component, and the retained control parameters of the unrestricted execution component; recalculate the upstream uncompleted response quantity and component command release conditions, and reconstruct the state transition segment that has not yet been executed.

[0015] Furthermore, the collaborative control module is connected to the sensor group, the variable frequency compressor drive board, the electronic expansion valve, the internal fan, the external fan, the ventilation fan, and the ventilation valve, respectively. The collaborative control process is as follows: converting the state transition sequence into target control instructions for each actuator; issuing target control instructions according to the state transition sequence; collecting control parameters, feedback parameters, and instructions from each actuator to complete feedback; and updating the current operating state group, upstream uncompleted response quantities, and component instruction release conditions based on the collected results.

[0016] The present invention has the following beneficial effects:

[0017] (1) The integrated intelligent ventilation variable frequency dehumidifier collaborative control system establishes an operation demand event chain by setting up air quality demand, temperature and humidity adjustment demand, timed ventilation demand, external forced commands and equipment protection commands according to the occurrence time, duration and involved components. Combined with compressor frequency, electronic expansion valve opening, fan speed, ventilation valve opening, refrigerant pressure and temperature feedback to generate current operation state group and target operation state group, the controller can identify the current effective demand, restricted execution components and allowable operating range in the same processing chain, retain ventilation or dehumidification tasks not restricted by protection commands, and reduce target coverage, component conflict and sudden change in the overall state caused by demand superposition, protection intervention and external commands occurring at the same time.

[0018] (2) The integrated intelligent ventilation variable frequency dehumidifier collaborative control system extracts the step adjustment segment of a single actuator from historical operating data, establishes the historical response relationship between the change in control command, the duration of command, the actual completion ratio and the related feedback change, and generates the upstream uncompleted response amount based on the response amplitude of the previous control command that has not yet been released, the air exchange airflow transmission order, the cooling and dehumidification response transmission order, the response transmission ratio and the influence coefficients on both sides, so that the next control command of the electronic expansion valve, compressor, fan and ventilation air valve is released according to the actual response progress, avoiding the superposition of directional conflict control actions when the previous command is still forming airflow, pressure or superheat changes, reducing pressure fluctuation, superheat deviation and air volume jump.

[0019] (3) The integrated intelligent ventilation variable frequency dehumidifier collaborative control system generates a state transition sequence from the current operating state group to the target operating state group on a cycle according to the component instruction release conditions. When the demand direction changes, it retains the state transition segment with the same transition direction and generates a back-off segment for the control parameters with the opposite transition direction. When the equipment protection instruction intervenes, it only restricts the associated execution component and reconstructs the transition segment that has not yet been executed. At the same time, it uses the actual control parameters, feedback parameters and instructions to complete the feedback update of the incomplete response quantity and release time, so that dehumidification, ventilation and equipment protection can be continuously connected according to the component response progress, reducing the overall shutdown, repeated start-up and shutdown and control instruction switching, and maintaining the smooth indoor air conditioning process.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] Figure 1 This is a block diagram of the integrated intelligent ventilation variable frequency dehumidifier collaborative control system of the present invention.

[0022] Figure 2 This is a flowchart illustrating the steps involved in forming the upstream uncompleted response quantity in the integrated intelligent ventilation variable frequency dehumidifier collaborative control system of this invention. Detailed Implementation

[0023] Please see Figure 1 This invention provides a technical solution: a variable frequency dehumidifier collaborative control system integrating intelligent ventilation, comprising: a demand event generation module, used to acquire air quality demand, temperature and humidity adjustment demand, timed ventilation demand, external forced commands, and equipment protection commands, and generate an operation demand event chain; an operation status generation module, used to collect control parameters, feedback parameters, changes in the previous control command, and command elapsed time of the ventilation execution chain and the refrigeration and dehumidification execution chain, generate a current operation status group, and generate a target operation status group containing target control parameters and equipment operation boundaries based on the operation demand event chain; and an incomplete response parsing module, used to generate... The system establishes historical response relationships, generates incomplete response values ​​based on the changes in the previous control command, the duration of the command, and historical response relationships, and generates upstream incomplete response quantities along the airflow transmission order and the cooling and dehumidification response transmission order; a release condition generation module generates component command release conditions based on upstream incomplete response quantities and the target operating state group; a state transition generation module generates a state transition sequence from the current operating state group to the target operating state group based on the component command release conditions; and a collaborative control module executes the state transition sequence, updates the current operating state group according to feedback parameters, and reconstructs unexecuted state transition segments when equipment protection commands intervene.

[0024] The ventilation execution chain includes ventilation damper, ventilation fan and indoor fan, and the refrigeration and dehumidification execution chain includes compressor, outdoor fan and electronic expansion valve. The controller records the target control command, actual control parameters, command issuance time and related feedback parameters of each execution component according to a unified control cycle.

[0025] After receiving the opening command, the ventilation damper needs to be driven by the motor and the transmission mechanism to reach the target position. After receiving the speed command, the ventilation fan needs to go through the rotor speed increase / decrease and the airflow establishment process in the duct. The compressor frequency change needs to go through refrigerant circulation and pressure establishment before acting on the evaporator. The electronic expansion valve opening change needs to go through valve needle action and refrigerant flow before being reflected to the evaporator outlet superheat. The evaporator heat exchange change needs to go through air mixing and duct delivery before being reflected to the return air detection position.

[0026] Historical response relationship records the correspondence between changes in control commands, command duration, actual completion rate, and changes in associated feedback parameters. Equipment operating boundaries are determined based on equipment manufacturing parameters, driver allowable range, and refrigeration circuit protection parameters.

[0027] Specifically, the process of forming the event chain of runtime requirements is as follows:

[0028] Air quality requirements and temperature and humidity control requirements are written into the demand intensity, occurrence time, and duration. Timed ventilation requirements and external mandatory commands are written into the target parameters, occurrence time, and duration, forming demand events, which are as follows:

[0029] Obtain the deviation between indoor air quality parameters and air quality target values, and determine the air quality demand intensity based on the demand calibration interval where the deviation is located.

[0030] Obtain the temperature deviation between the indoor temperature and the target temperature, and the humidity deviation between the indoor humidity and the target humidity. Determine the intensity of temperature and humidity regulation requirements based on the adjustment calibration range in which the temperature and humidity deviations fall.

[0031] The start time, end time, and target air exchange volume are read from the timed ventilation plan. The target execution component, target control parameters, and duration are read from the control commands sent by the building controller, user terminal, and linkage equipment, respectively forming timed ventilation demand events and externally forced demand events.

[0032] The demand calibration range and the adjustment calibration range are established based on the calibration results of the air exchange rate, compressor frequency and fan speed under different air quality deviations, temperature deviations and humidity deviations.

[0033] The device protection command is written into the restricted execution component and the device operating boundary to form a protection event, which is specifically as follows:

[0034] The protection trigger result is determined based on the exhaust temperature, refrigerant pressure and the operating status of each actuator. The restricted actuator corresponding to the protection trigger result is extracted, and the allowable frequency range, allowable opening range, allowable speed range, allowable temperature range and allowable pressure range are read from the equipment protection parameter table.

[0035] The equipment protection parameter table is established based on the equipment manufacturing parameters, the allowable range of the driver, the refrigeration circuit protection calibration results, and the whole machine protection test results. The hysteresis interval between the protection trigger value and the protection release value is determined based on the sensor measurement fluctuations and the protection parameter recovery process.

[0036] Arrange demand events and protection events according to their occurrence time, connect events with overlapping durations, connect protection events with demand events involving the same restricted execution component, and connect consecutive demand events corresponding to the same execution component in chronological order to generate a chain of operational demand events containing event identifier, demand intensity, target parameters, occurrence time, duration, and current effective status.

[0037] In one implementation, an air exchange demand event is generated when the indoor carbon dioxide concentration exceeds the air quality target value, a dehumidification demand event is generated when the indoor humidity exceeds the target humidity, and a compressor protection event is generated when the compressor exhaust temperature reaches the protection trigger value. The controller establishes the connection relationship between the air exchange demand, dehumidification demand, and compressor protection according to the occurrence time and duration of each event.

[0038] In this implementation plan, the operational requirement event chain records both operational requirements and equipment limitations. Even after equipment protection intervenes, the currently valid requirements that are not currently restricted are still retained, thus preventing new control commands from directly overriding control processes that are still being executed.

[0039] Specifically, the formation process of the current operating state group and the target operating state group is as follows:

[0040] The compressor frequency, electronic expansion valve opening, internal fan speed, external fan speed, ventilation fan speed, ventilation fan direction, and ventilation damper opening are collected to form a control parameter set, which is as follows:

[0041] The corresponding actual control parameters are collected through the variable frequency compressor drive board, electronic expansion valve driver, each fan drive end and ventilation valve position feedback end, and the collected results are arranged according to the control time scale.

[0042] The actual opening degree of the electronic expansion valve is determined based on the ratio of the current number of valve needle steps to the total number of allowable steps, and the actual opening degree of the ventilation damper is determined based on the calibration relationship between the position feedback value and the fully closed and fully open positions.

[0043] The system collects refrigerant pressure, suction temperature, discharge temperature, actual execution feedback from each actuator, and command completion feedback to form a set of feedback parameters, which are as follows:

[0044] Collect high-pressure side pressure, low-pressure side pressure, intake temperature and exhaust temperature, calculate the deviation between the actual control parameters and the target control parameters of each actuator, and form actual execution feedback;

[0045] Set the actual control parameter corresponding to the most recent target control command issuance time as the command start parameter, calculate the change of the current actual control parameter relative to the command start parameter, and calculate the target change of the current target control parameter relative to the command start parameter.

[0046] When two changes are in the same direction, divide the absolute value of the current actual change by the absolute value of the target change to obtain the actual completion ratio, and limit the actual completion ratio to between 0 and 1.

[0047] When two changes are in opposite directions, the actual completion rate is set to 0.

[0048] When the target change is 0, the actual completion rate is set to 1.

[0049] When the actual control parameters enter the target allowable range and remain continuously for the set number of control cycles, a completion marker is generated.

[0050] The target allowable range is determined based on the minimum effective adjustment of the driver, the sensor measurement error, and the parameter fluctuation range under stable operating conditions. The number of control cycles is set based on the driver feedback jitter record.

[0051] Extract the change in the previous control command and the duration of the command corresponding to each control parameter, specifically as follows:

[0052] Subtract the previous target control command from the most recent target control command to obtain the change in the previous control command; subtract the time of the most recent target control command from the current control time to obtain the command elapsed time.

[0053] The current operating status group is generated by combining the control parameter group, feedback parameter group, change of the previous control command, and command elapsed time according to the air exchange airflow transmission order and the refrigeration and dehumidification response transmission order. Specifically:

[0054] Arrange the control parameters of the ventilation execution chain and the associated feedback parameters on the evaporator side according to the airflow transmission sequence from the ventilation damper, ventilation fan and internal fan to the evaporator.

[0055] According to the refrigeration and dehumidification response transmission sequence from the compressor, outdoor fan, condenser, electronic expansion valve to the evaporator, the control parameters of the refrigeration and dehumidification execution chain and the associated feedback parameters of the refrigeration circuit are arranged, and the control parameters of each execution component are associated with the corresponding actual execution feedback, actual completion ratio, instruction completion mark, change of the previous control instruction and instruction elapsed time.

[0056] Based on the current valid demands and equipment protection commands in the operational demand event chain, the target control parameters and equipment operating boundaries are determined, and a target operating state group is generated, which is as follows:

[0057] Extract the current effective demand, determine the target ventilation volume based on the target ventilation volume in the air quality demand intensity and timed ventilation demand, determine the target temperature and target humidity based on the temperature and humidity regulation demand intensity, and read the target execution component and target control parameters in the external forced command; input the target ventilation volume, target temperature and target humidity into the equipment control calibration table, generate the target control parameters of the corresponding execution component, and update the target control parameters of the corresponding target execution component with the target control parameters in the external forced command;

[0058] The equipment control calibration table is established based on the control parameters of each actuator when it reaches a stable operating state under different target air exchange rate, temperature deviation and humidity deviation. When the target state is between adjacent calibration points, interpolation is used to determine the corresponding target control parameters.

[0059] Write the allowed parameter range corresponding to the protection event into the device operation boundary of the restricted execution component, and retain the target control parameters corresponding to the current valid requirements for the unrestricted execution component.

[0060] In this implementation scheme, the current operating state group and the target operating state group adopt the same execution component arrangement order, so that the current control parameters, the influence of the previous control command, and the target control parameters can correspond one by one.

[0061] Specifically, the formation process of historical response relationships and incomplete response values ​​is as follows:

[0062] The response segment extracted from historical operating data shows a step change in the control parameter of a single actuator while the control parameters of other actuators remain within the corresponding fluctuation range. Specifically:

[0063] The moment when the control parameters undergo a step change is taken as the starting point of the response segment. The baseline time period is extracted forward, and the response observation time period is extracted backward.

[0064] The reference period is the continuous period during which the actuators maintain stable operation before the step change, and the response observation period covers the process of the actual control parameters and associated feedback parameters changing from the reference value to the new stable value.

[0065] Detect the fluctuation range of the control parameters of other execution components during the response observation period, and retain the records with fluctuation ranges not higher than the screening threshold as response segments. The screening threshold is the 95th percentile value of the corresponding fluctuation range in the stable operation records of the same model.

[0066] Based on the elapsed time after the control command is issued, the actual execution feedback and related feedback parameter changes of the corresponding execution components are arranged to generate historical response relationships, which are as follows:

[0067] Set the control command issuance time to 0, and arrange the actual control parameters, actual completion rate, and changes in related feedback parameters according to the elapsed time.

[0068] Response segments are collected according to the direction of command change, the range of command change amplitude, and the range of operating conditions. The median of the response data corresponding to each elapsed duration is taken to form the historical response relationship between the change in control command, the elapsed duration of the command, the predicted completion ratio, and the change in the associated feedback parameters.

[0069] The range of command variation is divided according to the allowable control range of the actuator and the minimum effective adjustment of the driver, and the operating condition range is divided according to the calibrated range of indoor temperature and humidity, outdoor temperature and humidity and refrigerant pressure.

[0070] By substituting the change in the previous control command and the duration of the command into the historical response relationship, a predicted response for the previous control command that has not yet been released in the current control cycle is generated, specifically as follows:

[0071] ;

[0072] In the formula, Indicates the execution component During the control cycle The corresponding uncompleted response range, This represents the incomplete response value after assigning a response direction. Indicates the execution component number, Indicates the current control cycle. This indicates the control cycle preceding the current control cycle;

[0073] Indicates the execution component The corresponding change in the previous control command;

[0074] This indicates the complete response magnitude corresponding to the change in the previous control command;

[0075] This indicates the actual completion rate given by the feedback on command completion;

[0076] This indicates the predicted completion rate based on the elapsed time of the instruction, representing the historical response relationship.

[0077] Indicates the execution component During the control cycle The corresponding instruction elapsed time;

[0078] Indicates the execution component The corresponding feedback correction weight has a value range of [0, 1].

[0079] The complete response amplitude is obtained by dividing the complete change amplitude of the actual control parameter and the associated feedback parameter by the corresponding calibrated maximum change amplitude, and taking the average of the absolute values ​​of the normalized results; when the actuator has multiple associated feedback parameters, the average of the normalized change amplitudes of each associated feedback parameter is taken.

[0080] The actual response completion rate is determined based on the ratio between the absolute value of the change in the current associated feedback parameter and the absolute value of the change in the complete associated feedback parameter. The average deviations of the actual completion rate and the predicted completion rate relative to the actual response completion rate are calculated respectively. The average deviation corresponding to the predicted completion rate is divided by the sum of the two average deviations to obtain the feedback correction weight. When the sum of the two average deviations is 0, the feedback correction weight is set to 0.5.

[0081] The above calculation results represent the magnitude of the incomplete response. The direction of the incomplete response is determined based on the direction of change of the associated feedback parameter from the reference value to the stable value after the change of the previous control command in the historical response relationship. The magnitude of the incomplete response and the corresponding response direction are combined to form the incomplete response value. When the execution unit enters the target allowable range and maintains it continuously for the set number of control cycles, the incomplete response value is updated to 0.

[0082] If no response segment that meets the screening criteria is detected in the historical operating data, the historical response relationship generated during the factory calibration stage is used; if no less than 5 valid response segments are obtained in the same command change direction, operating condition range, and command change amplitude range, and the maximum deviation between the normalized peak value and the median peak value of the correlation feedback of each valid response segment is not higher than 10% of the median peak value, the median of the valid response segments is used to update the historical response relationship; the valid response segment must meet the following requirements: the control parameters of other actuators are within the corresponding fluctuation range, no equipment protection event has occurred, the sensor records are complete, and the response observation period covers the entire response process.

[0083] In one implementation, the historical response relationship of the ventilation valve records the valve plate positioning process and the ventilation volume establishment process; the historical response relationship of the compressor records the actual frequency arrival process, the refrigerant pressure change process, and the evaporator heat exchange change process; and the historical response relationship of the electronic expansion valve records the valve needle position change process and the actual superheat change process.

[0084] In this implementation scheme, the uncompleted response value represents the mechanical actions, airflow establishment, pressure establishment, refrigerant flow, and air mixing responses that have not yet been completed at the current control moment.

[0085] Specifically, such as Figure 2 As shown, the formation process of the upstream incomplete response quantity is as follows:

[0086] The incomplete response values ​​corresponding to the ventilation damper, ventilation fan, and indoor fan are normalized according to their respective maximum complete response amplitudes to generate incomplete airflow response values. The incomplete response values ​​corresponding to the compressor, outdoor fan, and electronic expansion valve are normalized according to their respective maximum complete response amplitudes to generate incomplete cooling and dehumidification response values, specifically as follows:

[0087] Read the maximum complete response amplitude under the same execution unit, the same instruction change direction, and the corresponding operating condition from the historical response relationship. Divide the incomplete response value by the corresponding maximum complete response amplitude to obtain the normalized incomplete response value, and retain the response direction; when the maximum complete response amplitude is 0, set the normalized incomplete response value to 0.

[0088] Based on the airflow transmission order and the cooling / dehumidification response transmission order, the upstream actuators corresponding to each actuator to be released are determined, specifically as follows:

[0089] Based on the equipment duct structure, establish the airflow transmission relationship between the ventilation valve, ventilation fan, internal fan and evaporator. Based on the refrigeration circuit structure, establish the refrigeration and dehumidification response transmission relationship between the compressor, condenser and electronic expansion valve and evaporator. Determine the preceding execution component whose response can be transmitted to the execution component to be released as the corresponding upstream execution component.

[0090] Based on historical response relationships, the response transmission ratio of each upstream actuator is determined, and the corresponding normalized results are weighted and accumulated to generate the upstream airflow response and the upstream refrigeration and dehumidification response, specifically as follows:

[0091] Extract the complete variation range of upstream control parameters and downstream feedback parameters from a single execution component response segment, normalize them according to the corresponding calibrated maximum variation range, and use the ratio between the normalized variation range of downstream feedback and the normalized variation range of upstream control as the response propagation ratio. When the normalized complete variation range of upstream control parameters is 0, the corresponding response segment is discarded and the response segment is not used to calculate the response propagation ratio.

[0092] The response delivery ratio is aggregated according to the same upstream execution unit, the execution unit to be released, and the delivery path, and the median value is taken to limit the response delivery ratio to between 0 and 1.

[0093] When there is a lack of operation records, the factory calibration result is used. If there is no corresponding transmission path in the factory calibration, the response transmission ratio is set to 0.

[0094] At the evaporator heat exchange correlation location, the airflow-side influence coefficient and refrigerant-side influence coefficient are determined based on the airflow-side response contribution value and the refrigerant-side response contribution value. Then, the upstream response quantities of the airflow and the upstream response quantities of the refrigeration and dehumidification processes are weighted and synthesized to generate the upstream incomplete response quantities of each actuator to be released.

[0095] ;

[0096] In the formula, Indicates the execution component to be released During the control cycle The corresponding upstream incomplete response amount, and the value is not less than 0. Indicates the number of the execution component to be released. Indicates the upstream execution component number;

[0097] This indicates that the relationship between the airflow and the actuator to be released can be transmitted. The set of upstream execution components;

[0098] This indicates that the ability to influence the actuator to be released is achieved through the transmission relationship of the refrigeration and dehumidification response. The set of upstream execution components;

[0099] Indicates the execution component During the control cycle The corresponding normalized incomplete response value, with the positive or negative sign indicating the response direction;

[0100] Indicates airflow-side actuator To the execution unit to be released The proportion of the response transmitted;

[0101] Indicates the cooling and dehumidification side actuator. To the execution unit to be released The proportion of the response transmitted;

[0102] Indicates the execution component to be released The corresponding airflow-side influence coefficient;

[0103] Indicates the execution component to be released The corresponding refrigerant-side influence coefficient;

[0104] , Both are located between [0, 1], and their sum is 1;

[0105] The process for determining the airflow-side influence coefficient and the refrigerant-side influence coefficient is as follows:

[0106] For each actuator to be released, determine the associated feedback parameters that can reflect the airflow-side response and the refrigerant-side response;

[0107] During the equipment factory calibration phase, the compressor frequency, external fan speed and electronic expansion valve opening are kept constant. Step control commands are applied to the ventilation valve, ventilation fan and internal fan respectively. The changes in the associated feedback parameters of the corresponding actuators to be released are recorded. The changes in each associated feedback parameter are divided by the corresponding maximum change in calibration. The absolute value of the normalized result is averaged to obtain the airflow side response contribution value.

[0108] Keeping the opening of the ventilation damper, the speed of the ventilation fan and the speed of the indoor fan constant, step control commands are applied to the compressor, the outdoor fan and the electronic expansion valve respectively, and the refrigerant side response contribution value is obtained in the same way.

[0109] Divide the airflow-side response contribution value by the sum of the airflow-side response contribution value and the refrigerant-side response contribution value to obtain the airflow-side influence coefficient; divide the refrigerant-side response contribution value by the sum of the two to obtain the refrigerant-side influence coefficient.

[0110] When both the airflow-side response contribution value and the refrigerant-side response contribution value are 0 and the actuator to be released is simultaneously affected by the transmission paths on both sides, both influence coefficients are set to 0.5.

[0111] When only the airflow side transmission path exists, set the airflow side influence coefficient to 1 and the refrigerant side influence coefficient to 0.

[0112] When only a refrigerant-side transmission path exists, set the refrigerant-side influence coefficient to 1 and the airflow-side influence coefficient to 0.

[0113] In one implementation, when the compressor starts to reduce its frequency due to a device protection command, the unfinished refrigeration and dehumidification response corresponding to the compressor is transmitted along the refrigeration circuit to the evaporator, and the unfinished airflow response corresponding to the ventilation valve and ventilation fan is transmitted along the air duct to the evaporator. Based on this, the controller generates the upstream unfinished response quantity of the corresponding execution component to be released.

[0114] In this implementation scheme, the upstream incomplete response quantity reflects the incomplete responses on the airflow side and the refrigerant side, and is used to determine whether the actuator to be released is still affected by the previous control command.

[0115] Specifically, the process of forming the component command release condition is as follows:

[0116] Based on the target control parameters, equipment operating boundaries, and historical response relationships in the target operating status group, the upstream incomplete response threshold for the corresponding execution component is determined, specifically as follows:

[0117] Calculate the target change range between the current control parameters and the target control parameters, and read the associated feedback parameters up to the remaining range of the equipment operating boundary;

[0118] Candidate thresholds are generated based on adjacent calibration values ​​of upstream uncompleted response quantities in the factory calibration.

[0119] For each candidate threshold, the corresponding upstream remaining feedback change is calculated based on the historical response relationship of each upstream execution component, the duration of the current instruction, and the response transmission ratio. The predicted feedback change corresponding to the control instruction to be released is calculated based on the target change magnitude between the current control parameters and the target control parameters, as well as the historical response relationship of the execution component to be released.

[0120] According to their respective response directions, the remaining upstream feedback change and the predicted feedback change corresponding to the control command to be released are superimposed on the current feedback parameter to obtain the predicted feedback parameter corresponding to each candidate threshold.

[0121] The maximum value is selected from the candidate thresholds where all associated feedback parameters are within the equipment operating boundary, and is used as the upstream incomplete response threshold. If there are no candidate thresholds that meet the conditions, the upstream incomplete response threshold is set to 0.

[0122] When historical records are missing for a corresponding operating condition, the smaller value among the thresholds corresponding to adjacent operating conditions in the factory calibration is used.

[0123] Based on historical response relationships, the predicted decay of upstream uncompleted response volume over the control cycle is as follows:

[0124] Based on the current instruction elapsed time of each upstream execution component, read the predicted completion ratio corresponding to the subsequent control cycle, update the incomplete response value of each execution component, and calculate the upstream incomplete response amount corresponding to each subsequent control cycle.

[0125] The predicted time domain coverage corresponds to the maximum value of the complete response time of the upstream execution component. The complete response time is the 95th percentile value of the time required for the corresponding response segment to enter the stable range from the issuance of the control command to the associated feedback parameter.

[0126] The first control cycle in which the upstream incomplete response amount is no higher than the corresponding threshold and the feedback parameters are within the equipment operating boundary is determined as follows:

[0127] ;

[0128] In the formula, Indicates the execution component to be released The corresponding first release control cycle;

[0129] This indicates the current control cycle at the time of calculating the release condition. Indicates the candidate control period in the prediction time domain;

[0130] Indicates the execution component to be released During the control cycle The corresponding upstream uncompleted response volume;

[0131] Indicates the execution component to be released The corresponding upstream incomplete response threshold;

[0132] Indicates the execution component to be released The corresponding number Each feedback parameter in the control cycle The corresponding predicted value;

[0133] Indicates the lower limit of allowable conditions. Indicates the maximum allowed limit;

[0134] Indicates the execution component to be released The corresponding set of feedback parameter numbers;

[0135] This means selecting the earliest control cycle from the candidate control cycles that meet all the conditions;

[0136] The predicted value of the feedback parameter is generated based on the current feedback parameter, the change in the corresponding control parameter, and the feedback change corresponding to the duration of the same command in the historical response relationship.

[0137] If no control cycle that meets the conditions exists in the prediction time domain, the current control parameters of the corresponding execution unit are maintained and recalculated in the next control cycle;

[0138] The first release control cycle, the upstream incomplete response threshold, the allowable range of associated feedback parameters, and the component number to be released are combined to form the component instruction release conditions.

[0139] In this implementation scheme, the release time of the control command is determined by the incomplete response decay result and the equipment operating boundary.

[0140] Specifically, the formation process of the state transition sequence is as follows:

[0141] Set the current running state group to the initial state, specifically as follows:

[0142] Copy the control parameters, feedback parameters, changes in the previous control command, command elapsed time, and equipment operating boundaries from the current operating status group, and write them into the starting control timestamp;

[0143] Before the component command release condition is met, the corresponding control parameters are maintained. After the component command release condition is met, the parameter change rate of the corresponding execution component is determined according to the historical response relationship, and the next operating state group is generated within the equipment operating boundary, which is as follows:

[0144] Determine whether each execution component has reached the corresponding first release control cycle, and verify the upstream incomplete response amount and feedback parameters;

[0145] Execution units that do not meet the release conditions maintain their current control parameters. Execution units that meet the release conditions extract the maximum unit control cycle parameter change that does not cause the associated feedback parameter to exceed the limit under the same change direction and similar operating conditions from the historical response relationship, and use this unit control cycle parameter change as the parameter change rate.

[0146] When there is no corresponding record in the historical response relationship, the smallest unit control cycle parameter change corresponding to the same change direction during the factory calibration stage shall be used.

[0147] The next control parameter, generated according to the parameter change rate, will be limited to the range between the current control parameter and the target control parameter, and will be confined within the equipment operating boundary.

[0148] The upstream unfinished response quantity and component command release conditions are recalculated based on the next operating state group, specifically as follows:

[0149] Write the difference between the next control parameter and the current control parameter into the new control command change amount, write the control timestamp corresponding to the next running state group into the command issuance time, predict the incomplete response value and associated feedback parameter change amount corresponding to the new control command, and update the upstream incomplete response amount and the first release control cycle of each execution component to be released;

[0150] The next running state group is generated repeatedly until the target running state group is reached, forming a state transition sequence, which is as follows:

[0151] Compare the target control parameters in the next operating state group and the target operating state group on a cycle-by-cycle basis. Stop the recursion when all control parameters enter the corresponding target allowable range and the feedback parameters are within the equipment operating boundary. Arrange the initial state and each next operating state group according to the control time scale to form a state transition sequence.

[0152] In one implementation, when switching from the parallel dehumidification and fresh air state to the compressor frequency reduction protection state, the compressor target frequency decreases according to the equipment operating boundary, and the opening of the electronic expansion valve is adjusted after the upstream uncompleted response amount corresponding to the compressor decreases to the upstream uncompleted response threshold. The ventilation damper and ventilation fan determine the release time of the control command based on the evaporator airflow side response and the refrigerant side response.

[0153] In this implementation scheme, the state transition sequence breaks down the overall state switching into control processes released according to the response progress, reducing pressure fluctuations, superheat shifts, and air volume changes caused by simultaneous sudden changes in the compressor, electronic expansion valve, and ventilation actuator.

[0154] Specifically, the processing procedure when the demand event chain changes in reverse is as follows:

[0155] When the event chain of operational requirements changes in reverse, the actual control parameters and feedback parameters of each execution component are collected, and an updated current operational status group is generated, which is as follows:

[0156] When the direction of change of the target control parameter is opposite to the current migration direction, the current actual control parameter and feedback parameter are collected, and the collection results are written into the updated current running status group;

[0157] The updated target running state group is generated based on the reversed running requirement event chain, specifically as follows:

[0158] Update the demand intensity, duration, and current valid status of the corresponding demand events, retain the protection events that are still valid, and generate target control parameters based on the updated current valid demands;

[0159] The migration direction of each control parameter in the updated current operating state group and the updated target operating state group is compared, specifically as follows:

[0160] Calculate the difference between the target control parameter and the current control parameter. If the direction of the difference is the same as the current migration direction, retain the corresponding migration segment. If the direction of the difference is opposite, set the current control parameter as the starting point of the reverse migration.

[0161] Read the control parameter corresponding to the most recent component instruction release condition that has been met and feedback verification has been completed, and set it as the rollback target parameter; if there is no corresponding control parameter, set the control parameter corresponding to the initial state as the rollback target parameter.

[0162] Based on the historical response relationship, the parameter change rate of the reverse migration is determined. A reverse migration segment from the reverse migration start point to the rollback target parameter is generated within the equipment operating boundary. Then, the state migration sequence to the updated target operating state group is regenerated with the end point of the reverse migration segment as the starting point.

[0163] In one implementation, when the ventilation valve is in the process of increasing its opening, the air quality requirement is released. The controller reads the opening of the ventilation valve that most recently met the component command release condition as the backoff target parameter, generates a reverse migration segment according to the historical response relationship corresponding to the reverse action of the ventilation valve, and generates the remaining state migration sequence corresponding to closing the ventilation valve after reaching the backoff target parameter.

[0164] Specifically, the reconstruction process when a device protection command intervenes is as follows:

[0165] Extract the restricted execution component, allowed control range, allowed feedback range, and protection release condition corresponding to the current effective protection event from the operational demand event chain, and determine the equipment operation boundary of the restricted execution component;

[0166] When the current control parameter of the restricted execution component is higher than the upper limit of allowable control, the target control parameter is set to the upper limit of allowable control; when it is lower than the lower limit of allowable control, the target control parameter is set to the lower limit of allowable control; when it is within the allowable range, the target control parameter is generated according to the adjustment direction specified by the protection instruction.

[0167] When the protection command does not specify the target control parameters, the target control parameters for the corresponding protection level are read from the equipment protection parameter table.

[0168] Unrestricted execution components retain the current control parameters and redetermine the target control parameters based on the current valid requirements in the operational requirement event chain, generating an updated target operational state group;

[0169] The changes in control parameters caused by protection intervention are taken as the changes in the previous control command. Based on the historical response relationship, the incomplete response values ​​corresponding to the restricted execution components are generated. The upstream incomplete response quantities and the first release control cycle of each execution component to be released are recalculated. The state transition segments that have not yet been executed are reconstructed starting from the current operating state group.

[0170] In one implementation, when the compressor exhaust temperature reaches the protection trigger value, the compressor target frequency is limited to the protection allowable frequency range, and the internal fan, ventilation fan and ventilation valve retain the current control parameters;

[0171] When the refrigerant cycle response corresponding to the compressor frequency reduction has not yet completely decayed, delay the time when the ventilation damper increases its opening.

[0172] When the evaporator temperature approaches the frosting protection boundary, reduce the target opening of the ventilation damper and control the ventilation fan according to the minimum exhaust volume corresponding to the air quality requirements.

[0173] In this implementation scheme, after the equipment protection command intervenes, protection adjustments are performed on the restricted execution components, and the control timing of the unrestricted execution components is rearranged based on the new response generated by the protection adjustment.

[0174] Specifically, the collaborative control module is connected to the sensor group, the variable frequency compressor drive board, the electronic expansion valve, the internal fan, the external fan, the ventilation fan, and the ventilation valve, respectively. The collaborative control process is as follows:

[0175] The state transition sequence is converted into target control instructions for each execution unit, specifically as follows:

[0176] Read the compressor target frequency, electronic expansion valve target opening, each fan target speed, ventilation fan target direction and ventilation valve target opening from each operating status group, and convert them into corresponding frequency conversion drive commands, step pulse commands, speed commands, direction commands and valve opening commands;

[0177] The target control command is issued according to the state transition sequence, specifically as follows:

[0178] Read the operating status group according to the control time stamp, and issue the target control command when the corresponding component command release condition is met; otherwise, maintain the previous target control command.

[0179] The feedback is completed by collecting control parameters, feedback parameters, and commands from each actuator, specifically as follows:

[0180] In each control cycle, the actual control parameters, refrigerant pressure, suction temperature and discharge temperature of each actuator are collected, and the actual completion ratio and instruction completion mark are generated based on the deviation between the actual control parameters and the target control parameters.

[0181] The current running status group, upstream incomplete response amount, and component instruction release conditions are updated based on the collected results, specifically as follows:

[0182] The collected results are written into the current running status group. The uncompleted response values ​​of each execution component are corrected according to the actual completion ratio. The upstream uncompleted response amount and the first release control cycle corresponding to the execution component that has not yet been released are recalculated, and the subsequent state transition segment is executed accordingly.

[0183] In this implementation scheme, the collaborative control module issues control commands according to the state transition sequence and uses actual execution feedback to update incomplete responses and subsequent release times.
