However, the detection of air parameters at the return air vent can be affected by the operating status of the indoor unit itself or external factors, resulting in a significant deviation between the detected air status data and the actual air status in the external indoor environment. This can seriously affect the accuracy of the system's regulation of the indoor space environment. Summary of the Invention

[0055] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0056] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0057] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0058] The main solution of this application embodiment is: to obtain state parameters representing the air state of the target space where the indoor unit is located, and operating scenario parameters of the indoor unit, wherein the state parameters are obtained based on detection data in the indoor unit; to determine the indoor environmental parameters of the target space based on the state parameters and the operating scenario parameters; and to control the operation of the environmental control system based on the indoor environmental parameters.

[0059] In this embodiment, for ease of description, the environmental control system will be used as the implementing entity for the following description.

[0060] Due to existing technology, sensors are typically installed at the return air vent of the indoor unit to detect the status parameters of the return air, which are then used as the indoor environmental parameters required for system operation and control. However, the detection of air parameters at the return air vent can be affected by the operating status of the indoor unit itself or external factors. For example, after the indoor unit is turned off, the cooling or heating capacity of the coil in the duct can cause deviations in the detection by the return air vent sensor. Furthermore, the return air vent is usually located low and is easily affected by indoor air stratification, resulting in a large deviation between the detected air status data and the actual air status in the external indoor environment. This can seriously affect the accuracy of the system's control over the indoor space environment.

[0061] This application provides the above-mentioned solution to improve the accuracy of the system's environmental control of indoor spaces.

[0062] This embodiment provides an environmental control system that can be used to regulate the air quality in an indoor space.

[0063] In this embodiment of the invention, reference is made to Figure 1 The environmental control system includes a heat pump system 100 and a refrigerant circulation system 200, with the heat pump system 100 and the refrigerant circulation system 200 connected for heat exchange.

[0064] The heat pump system 100 includes a compressor, a reversing assembly, a first heat exchanger, a throttling device, and a second heat exchanger. The first heat exchanger, the throttling device, and the second heat exchanger are connected in sequence. The compressor's exhaust port, compressor's return port, the first heat exchanger, and the second heat exchanger are all connected to the reversing assembly. The heat pump system 100 also includes an indoor unit 11 and a refrigerant regulation module 12. The indoor unit 11 is connected in parallel with the second heat exchanger.

When the refrigerant flows through the heat exchange module, it can exchange heat with the refrigerant in the second heat exchanger.

The types of indoor terminal devices 22 in different indoor spaces can be the same or different. When there is more than one indoor terminal device 22, one or more types of indoor terminal devices 22 can be installed in each indoor space. Alternatively, when there is more than one indoor terminal device 22, the more than one indoor terminal device 22 can be connected in parallel. For example, the environmental control system is configured to regulate at least two indoor spaces, each with a radiant terminal device, or each indoor space with both a convection heat exchange device and a radiant terminal device, or each indoor space with only a convection heat exchange device.

[0100] Based on this, embodiments of this application provide a control method for an environmental control system, referring to... Figure 3 , Figure 3 This is a flowchart illustrating the first embodiment of the control method for the environmental control system of this application.

[0101] In this embodiment, the control method of the environmental control system includes steps S10 to S30:

[0102] Step S10: Obtain status parameters representing the air state of the target space where the indoor unit is located, and operating scenario parameters of the indoor unit, wherein the status parameters are obtained based on the detection data in the indoor unit;

[0103] In this embodiment, the state parameters may include temperature state parameters representing indoor temperature state and / or humidity state parameters representing indoor humidity state, etc.

[0104] Status parameters can be obtained directly from the detection module in the indoor unit, or they can be calculated based on the data detected by the detection module in the indoor unit.

[0105] Status parameters may include indoor air status parameters detected by sensors installed in the indoor unit (such as return air temperature and / or indoor heat exchanger inlet air temperature and / or fresh air temperature, etc.). In addition to indoor air status parameters, status parameters may further include other status parameters in the indoor unit that affect the detection of air status parameters in the indoor air duct (such as indoor heat exchanger temperature and / or indoor air duct fresh air inlet temperature and / or indoor air duct exhaust temperature in the exhaust air duct connected to the indoor air duct heat exchange, etc.).

[0106] Operating scenario parameters may include any data that affects the indoor air quality as indicated by the detection data in the indoor unit during the indoor unit's operating scenario. Operating scenario parameters may include the operating status parameters of the environmental control system itself (e.g., at least one of the following: on / off status, dehumidification capacity, heat exchange capacity, outlet air temperature, radiant surface temperature, fan speed, etc.) and / or the operating status parameters of the equipment in the target space outside the environmental control system (e.g., at least one of the following: on / off status, dehumidification capacity, heat exchange capacity, outlet air temperature, radiant surface temperature, fan speed, etc.).

[0107] In this embodiment, step S10 is executed when the environmental control system is in heating mode. When the environmental control system is in heating mode, the heat pump system operates in heating mode, and the indoor unit is in heating mode. If the environmental control system also includes an indoor terminal device, the activated indoor terminal device is in heating mode. In other embodiments, step S10 is executed when the environmental control system is in cooling mode.

[0108] Furthermore, in this embodiment, when the environmental control system is in heat exchange state, it can obtain the status information of the ambient temperature sensor outside the indoor unit in the target space. If there is an ambient temperature sensor outside the indoor unit in the target space, it can obtain the indoor temperature detected by the ambient temperature sensor and control the operation of the environmental control system according to the obtained indoor temperature; if there is no ambient temperature sensor outside the indoor unit in the target space, it can execute step S10.

[0109] Step S20: Determine the indoor environmental parameters of the target space based on the state parameters and the operating scenario parameters;

[0110] In this embodiment, the indoor environmental parameters include indoor temperature. In other embodiments, the indoor environmental parameters may also include indoor humidity and / or indoor enthalpy, etc.

[0111] In one implementation, a relationship between state parameters, operating scenario parameters, and indoor environmental parameters can be pre-established. Substituting the current state parameters and operating scenario parameters into this relationship yields the indoor environmental parameters. In another implementation, parameter correction values ​​can be determined based on the operating scenario parameters, and these correction values ​​can be used to adjust the state parameters to obtain the indoor environmental parameters.

[0112] When there is more than one indoor unit, the indoor ambient temperature of the target space where each indoor unit is located can be determined based on the status parameters and operating scenario parameters of the indoor unit in that target space.

[0113] Step S30: Control the operation of the environmental control system according to the indoor environmental parameters.

[0114] In this embodiment, the environmental control system includes a heat pump system and a refrigerant circulation system. The operation of the heat pump system and / or the refrigerant circulation system can be controlled according to indoor environmental parameters. The controlled objects may include at least one of the following: a compressor in the heat pump system, a fan in the heat pump system, a throttling device in the heat pump system, a fluid regulation module in the refrigerant circulation system, a circulation pump in the refrigerant circulation system, a fan in the refrigerant circulation system, etc.

[0115] This embodiment provides a control method for an environmental regulation system. In this method, the indoor environmental parameters used for system operation control are no longer determined solely based on the indoor air state parameters determined by the detection data in the indoor unit. Instead, they are determined by combining the state parameters with the operating scenario parameters of the indoor unit. This reduces the error in indoor environmental parameters caused by the operating scenario and ensures that the indoor environmental parameters used for system control can match the actual air state in the indoor environment, thereby effectively improving the accuracy of the system's environmental regulation of the indoor space.

[0116] Furthermore, in this embodiment, the indoor terminal device includes a radiant terminal device installed on the floor of the target space. Its operation, whether open or closed, affects the temperature of the lower area of ​​the target space. The return air vent of the indoor unit is located in the lower area of ​​the target space.

[0117] Based on any of the above embodiments, in the second embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. On this basis, the environmental control system includes at least two indoor units, the status parameters include the return air temperature of the indoor unit and the heat exchanger temperature of the indoor unit, and / or, the operating scenario parameters include the on / off status of at least two indoor units and / or the on / off status of the indoor terminal devices in the target space; wherein, the indoor environmental parameters include the indoor ambient temperature.

[0118] The return air temperature can be detected by a temperature sensor located at the return air vent of the indoor unit.

[0119] The heat exchanger temperature may include at least one of the following: the mid-temperature of the indoor heat exchanger, the inlet temperature of the indoor heat exchanger, the outlet temperature of the indoor heat exchanger, etc. In this embodiment, the heat exchanger temperature includes the mid-temperature of the indoor heat exchanger and the inlet temperature of the indoor heat exchanger.

[0120] The on / off status of at least two indoor units includes the on / off status of each indoor unit.

[0121] In an environmental control system, at least two indoor units are connected in parallel. The electronic expansion valve of the indoor unit in operation operates at an opening greater than the standby opening, and the indoor fan in the indoor unit is on. The electronic expansion valve of the indoor unit not in operation operates at the standby opening, and the indoor fan in the indoor unit is off. Here, the standby opening is a very small opening, used to ensure pressure balance during system operation and improve operational reliability and stability.

[0122] The indoor terminal device in the target space is configured to regulate the air conditions of the target space. In this embodiment, the indoor terminal device is a device in the aforementioned refrigerant circulation system. In other embodiments, the indoor terminal device may also be a device that operates independently of the environmental control system, such as a heater or dehumidifier.

[0123] Based on this, step S20 may include: determining the indoor ambient temperature based on the on / off status of at least two of the indoor units and / or the on / off status of the indoor terminal devices in the target space, the return air temperature, and the heat exchanger temperature.

[0124] In one feasible implementation, temperature adjustment parameters can be determined based on the on / off status of at least two indoor units and / or the on / off status of indoor terminal equipment in the target space. The return air temperature is corrected based on the heat exchanger temperature to obtain a reference indoor temperature. The reference indoor temperature is then adjusted based on the temperature adjustment parameters to obtain the indoor ambient temperature.

[0125] In another feasible implementation, the on / off states of at least two of the indoor units and / or the on / off states of the indoor terminal devices in the target space, the return air temperature, the heat exchanger temperature and the indoor ambient temperature can be pre-established, and the indoor ambient temperature can be calculated by substituting the above-mentioned known parameters into the relationship.

[0126] In another feasible implementation, a target correspondence between the return air temperature, the heat exchanger temperature, and the indoor ambient temperature is determined based on the on / off states of at least two indoor units and / or the on / off states of indoor terminal devices in the target space; the indoor ambient temperature is then determined based on the target correspondence, the heat exchanger temperature, and the return air temperature. Here, different on / off states of at least two indoor units and / or indoor terminal devices result in different target correspondences. The target correspondence may include formulas or mapping relationships, for example, the mapping relationship can be set as a mapping relationship between different return air temperature ranges, heat exchanger temperature ranges, and indoor ambient temperatures. When the target correspondence includes formulas, the heat exchanger temperature and return air temperature can be substituted into the formulas to calculate the indoor ambient temperature. The target correspondence includes mapping relationships between different temperature ranges and indoor ambient temperatures, which can determine the first temperature range where the heat exchanger temperature is located, the second temperature range where the return air temperature is located, and the temperature mapped by the first and second temperature ranges as the current indoor ambient temperature of the target space. In this embodiment, since the indoor heat exchanger affects the accuracy of the return air temperature in representing the room temperature, the on / off status of each indoor unit affects the refrigerant flow in the indoor unit in the target space, thus affecting the accuracy of the room temperature representation, and the on / off status of the indoor terminal equipment affects the temperature distribution in the target space, the heat exchanger temperature and the on / off status of the indoor unit and / or terminal equipment can accurately reflect the deviation between the indoor temperature represented by the return air temperature and the actual temperature of the target space. Combining the on / off status, return air temperature, and heat exchanger temperature to determine the indoor ambient temperature can improve the fit between the indoor ambient temperature and the actual temperature of the indoor space. Therefore, based on the operation of this indoor ambient temperature control system, the accuracy of the system's environmental regulation of the indoor space can be effectively improved.

[0127] Furthermore, in this embodiment, referring to Figure 4 The step of determining the indoor environmental parameters of the target space based on the state parameters and the operating scenario parameters includes steps S21 to S22:

[0128] Step S21: Determine the first coefficient corresponding to the return air temperature and the second coefficient corresponding to the heat exchanger temperature based on the on / off status of at least two indoor units and / or the on / off status of indoor terminal devices in the target space.

[0129] Different on / off states of at least two indoor units and / or the on / off states of indoor terminal devices in the target space correspond to different first and second coefficients. The correspondence between the on / off states and the first and second coefficients can be preset, and the correspondence can include calculation formulas or mapping tables, etc. Based on this correspondence, the first and second coefficients corresponding to the current on / off states of at least two indoor units and / or the on / off states of indoor terminal devices in the target space can be determined.

[0130] The first and second coefficients can represent the weights of the corresponding temperatures in the process of fitting the indoor ambient temperature. The larger the coefficient value, the greater the weight, which means that the greater the contribution to reducing the deviation between the indoor ambient temperature and the actual temperature state of the target space.

[0131] Step S22: Determine the indoor ambient temperature based on the return air temperature and the corresponding first coefficient, and the second coefficient corresponding to the heat exchanger temperature.

[0132] The indoor ambient temperature can be calculated by substituting the return air temperature, the first coefficient, the heat exchanger temperature, and the second coefficient into a preset formula. Alternatively, a first temperature can be determined using the first coefficient and the return air temperature, a second temperature can be determined using the second coefficient and the heat exchanger temperature, and the indoor ambient temperature can be determined based on the first and second temperatures.

[0133] In this embodiment, the above method helps to further improve the matching degree between the indoor ambient temperature and the actual indoor temperature state, thereby further improving the accuracy of the system's environmental control of the indoor space.

[0134] Furthermore, the heat exchanger temperature includes the middle temperature of the indoor heat exchanger and the inlet temperature of the indoor heat exchanger. The second coefficient includes a first sub-coefficient corresponding to the middle temperature and a second sub-coefficient corresponding to the inlet temperature. The first sub-coefficient is greater than the second sub-coefficient. Therefore, the indoor ambient temperature can be determined based on the return air temperature and the corresponding first coefficient, the middle temperature and the corresponding first sub-coefficient, and the inlet temperature and the corresponding second sub-coefficient. Based on this, the step of determining the indoor ambient temperature based on the return air temperature and the corresponding first coefficient, and the second coefficient corresponding to the heat exchanger temperature includes: determining a weighted middle temperature based on the first sub-coefficient and the middle temperature; determining a weighted inlet temperature based on the second sub-coefficient and the inlet temperature; determining a weighted return air temperature based on the first coefficient and the return air temperature; determining the heat exchange temperature difference of the indoor heat exchanger based on the temperature difference between the weighted middle temperature and the weighted inlet temperature; and determining the indoor ambient temperature based on the weighted return air temperature and the heat exchange temperature difference.

[0135] The heat exchange temperature difference value represents the actual heat exchange capacity of the corresponding indoor heat exchanger.

[0136] In this embodiment, the product of the first coefficient and the return air temperature is used as the weighted return air temperature, the product of the first sub-coefficient and the middle temperature is used as the weighted middle temperature, and the product of the second sub-coefficient and the inlet temperature is used as the weighted return air temperature. In other embodiments, the first coefficient, the first sub-coefficient, and the second sub-coefficient may also be the adjustment range of the corresponding temperature.

[0137] In this embodiment, the indoor ambient temperature is determined based on the sum of the weighted return air temperature and the heat exchange temperature difference.

[0138] To better understand the solution involved in this embodiment, the following is an explanation of the solution in this embodiment with a specific example. Define the third coefficient as a, the first coefficient as b, the return air temperature as T1, the first sub-coefficient as c, the middle temperature as T2, the second sub-coefficient as d, and the inlet temperature as T2'. Then, the indoor ambient temperature T can be determined based on the following relationship: T = a + b*T1 + c*T2 - d*T2'. Here, b*T1 can be understood as the weighted return air temperature, c*T2 can be understood as the weighted middle temperature, d*T2' can be understood as the weighted inlet temperature, and c*T2 - d*T2' can be understood as the heat exchange temperature difference.

[0139] In this embodiment, the above method helps to further improve the fit between the indoor ambient temperature and the actual temperature state of the target space, thereby further improving the accuracy of the system's environmental control of the indoor space.

[0140] In other embodiments, the temperature difference between the middle temperature and the inlet temperature can also be determined, and the heat exchange temperature difference value can be obtained by adjusting the temperature difference value according to the second coefficient.

[0141] Furthermore, in this embodiment, the step of determining the first coefficient corresponding to the return air temperature and the second coefficient corresponding to the heat exchanger temperature based on the on / off status of at least two indoor units and / or the on / off status of the indoor terminal devices in the target space includes: when there is an indoor unit that is turned on among the at least two indoor units, determining the first parameter as the first coefficient and determining the second parameter as the second coefficient; when there is no indoor unit that is turned on among the at least two indoor units and the indoor terminal devices in the target space are in the on state, determining the third parameter as the first coefficient and determining the fourth parameter as the second coefficient; wherein, the first parameter is less than the third parameter, and the second parameter is greater than the fourth parameter.

[0142] In this embodiment, the first parameter, the second parameter, the third parameter, and the fourth parameter can be preset fixed values. In other embodiments, the first parameter, the second parameter, the third parameter, and the fourth parameter can be determined based on the actual operating conditions of at least two indoor units and indoor terminal devices. For example, the first coefficient and the second coefficient can be further determined based on whether the indoor units in the target space are turned on and / or the number of indoor units that are turned on and / or the number of indoor terminal devices that are turned on and / or the characteristic parameters of the indoor terminal devices indicating the amount of heat exchange.

[0143] When the indoor terminal device is a radiant terminal device, the indoor terminal device can be considered to be in the on state when the corresponding sub-regulation module of the radiant terminal device is turned on. The sub-regulation module is used to regulate the flow rate of the corresponding radiant terminal device. When the indoor terminal device is a convection terminal device, the indoor terminal device can be considered to be in the on state when the fan in the convection heat exchange device is turned on.

[0144] The heat exchanger temperature includes the middle temperature of the indoor heat exchanger and the inlet temperature of the indoor heat exchanger. The second parameter includes a first value corresponding to the middle temperature and a second value corresponding to the inlet temperature. The first value is determined as a first sub-coefficient, and the second value is determined as a second sub-coefficient. The fourth parameter includes a third value corresponding to the middle temperature and a fourth value corresponding to the inlet temperature. The third value is determined as a first sub-coefficient, and the fourth value is determined as a second sub-coefficient.

[0145] To better understand the solution involved in this embodiment, a specific example is given below: Based on the aforementioned T = a + b * T1 + c * T2 - d * T2', when at least one of the two indoor units is turned on, a = 0, b = 0.972 (first parameter), c = 0.120 (first value), and d = 0.162 (second value); when at least two indoor units are turned off and the indoor terminal device in the target space is turned on, a = 0, b = 1.395 (third parameter), c = 0.114 (third value), and d = 0.539 (fourth value).

[0146] In this embodiment, the above method helps to improve the accuracy of indoor unit temperature control in different operating scenarios.

[0147] Furthermore, when at least two indoor units are in operation, the first and second coefficients can be further determined based on whether the indoor units in the target space are in operation and / or the number of indoor units in operation.

[0148] Based on any of the above embodiments, in the third embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. Based on this, the environmental control system includes a heat pump system and a refrigerant circulation system. The heat pump system is heat-exchange connected to the refrigerant circulation system. The refrigerant circulation system includes indoor terminal equipment. The indoor environmental parameters include indoor ambient temperature. Step S30 includes: controlling the operation of a sub-regulation module corresponding to the indoor terminal equipment in the target space according to the indoor ambient temperature, the sub-regulation module being configured to adjust the refrigerant flow rate of the corresponding indoor terminal equipment; and / or, determining the target liquid supply temperature of the gas equipment in the refrigerant circulation system according to the indoor ambient temperature, and controlling the operation of the gas equipment according to the target liquid supply temperature.

[0149] The operation of corresponding sub-regulation modules is controlled based on the indoor ambient temperature. For example, the operation of a sub-regulation module can be controlled based on the relationship between the indoor ambient temperature and the set temperature of the target space. Different sub-regulation modules are controlled according to the indoor ambient temperature of their respective spaces.

[0150] This can be based on the indoor ambient temperature determined at the current moment, or it can be based on the indoor ambient temperature determined at more than one moment, to control the corresponding sub-regulation module.

[0151] The target supply temperature refers to the target temperature of the refrigerant flowing out of the refrigerant flow path in the gas-fired equipment.

[0152] The target liquid supply temperature can be determined based on the current indoor ambient temperature or based on the indoor ambient temperature determined at more than one time.

[0153] The controlled objects for gas equipment operation based on the target liquid supply temperature include at least one of the following: the opening degree of the gas proportional valve, the number of ignitions in the burner, the air intake, etc.

[0154] When the gas appliance is turned on and the heat pump system is in heating mode, both the heat pump system and the gas appliance provide heat to the indoor terminal equipment simultaneously; when the gas appliance is turned on but the heat pump system is turned off, the gas appliance alone provides heat to the indoor terminal equipment.

[0155] In this embodiment, the above method helps to further improve the accuracy of the system in regulating the indoor space temperature.

[0156] Furthermore, in this embodiment, the step of controlling the operation of the sub-regulation module corresponding to the indoor terminal device in the target space according to the indoor ambient temperature includes: determining the temperature change trend in the target space based on at least two successively detected indoor ambient temperatures, determining the temperature difference between the currently detected indoor ambient temperature and the set ambient temperature of the target space; and controlling the operation of the sub-regulation module corresponding to the target space according to the temperature change trend and the temperature difference.

[0157] At least two indoor ambient temperatures are required, including the current temperature and the temperature at the previous detection time. The interval between the current time and the previous detection time is preset. The temperature difference is obtained by subtracting the indoor ambient temperature at the previous detection time from the current temperature. If the temperature difference is greater than 0, the trend is upward; if the temperature difference is less than 0, the trend is downward; and if the temperature difference is 0, the trend remains unchanged.

[0158] Set the ambient temperature to the target value that the indoor temperature in the preset target space needs to reach. The temperature difference value is the difference between the indoor ambient temperature and the set ambient temperature.

[0159] In this embodiment, when the temperature change trend and the temperature difference value meet preset conditions, the corresponding sub-regulation module is turned on; when the temperature change trend and the temperature difference value do not meet the preset conditions, the corresponding sub-regulation module is turned off; wherein, the preset conditions include at least one of the following: the temperature change trend is an upward trend or remains unchanged and the temperature difference value is less than a first parameter, the temperature change trend is a downward trend and the temperature difference value is less than a second parameter.

[0160] In this embodiment, the indoor terminal device includes a radiant terminal device.

[0161] In this embodiment, the above method facilitates accurate control of the heat exchange output of the indoor terminal equipment, thereby further improving the accuracy of the system's control over the indoor space temperature.

[0162] In other embodiments, the target opening degree of the corresponding sub-regulation module can also be determined based on the temperature change trend and temperature difference value, and the corresponding sub-regulation module can be controlled to operate at the target opening degree.

[0163] Furthermore, in this embodiment, the step of determining the target liquid supply temperature of the gas equipment in the refrigerant circulation system based on the indoor ambient temperature includes: determining a temperature difference value and a temperature difference change value based on at least two successively detected indoor ambient temperatures, wherein the temperature difference value is the difference between the indoor ambient temperature and the set temperature, and the temperature difference change value is the change in the difference between the indoor ambient temperature and the set temperature; determining a temperature adjustment parameter based on the temperature difference value and the temperature difference change value; and adjusting the target value of the current liquid supply temperature of the gas equipment based on the temperature adjustment parameter to obtain the target liquid supply temperature.

[0164] The at least two indoor ambient temperatures here can include the indoor ambient temperatures corresponding to the current time and the previous detection time before the current time, with a preset time interval between the current time and the previous detection time.

[0165] Each indoor ambient temperature can be compared with the corresponding set temperature to determine the corresponding temperature difference value, obtaining at least two temperature difference values. Based on these at least two temperature difference values, the temperature difference change value can be determined.

[0166] Temperature adjustment parameters may include temperature adjustment amplitude or temperature adjustment ratio. Different temperature difference values ​​and temperature difference change values ​​correspond to different temperature adjustment parameters. In this embodiment, the temperature adjustment parameters can be calculated by substituting the temperature difference value and temperature difference change value into a preset formula.

[0167] The target value for the current liquid supply temperature can be a parameter configured by the user, a preset fixed parameter, or a parameter determined based on the actual operating status of the environmental control system.

[0168] In this embodiment, the above method can effectively improve the accuracy of the heating output of the gas equipment, thereby ensuring that the gas equipment and the heat pump system work together to accurately provide the required heat to the indoor space, further improving the accuracy of the system's temperature adjustment of the indoor space and effectively improving the comfort of indoor users.

[0169] In other embodiments, the target liquid supply temperature may also be determined based on one of the current indoor ambient temperature and / or the temperature difference value and the temperature difference change value.

[0170] Furthermore, in this embodiment, the step of determining the target liquid supply temperature of the gas equipment in the refrigerant circulation system based on the indoor ambient temperature includes: determining the target liquid supply temperature based on at least two indoor ambient temperatures corresponding to at least two target spaces.

[0171] The number of indoor ambient temperatures corresponding to each target space can be one or more. In this embodiment, each target space corresponds to a temperature data set, which includes at least two indoor ambient temperatures detected sequentially for the corresponding space. The target liquid supply temperature is determined based on at least two temperature data sets.

[0172] The sub-target liquid supply temperature of the indoor terminal device in each target space is determined according to the indoor ambient temperature, and the target liquid supply temperature is determined based on at least two sub-target liquid supply temperatures. In this embodiment, the corresponding sub-target liquid supply temperature is determined based on the temperature data set corresponding to each target space. Specifically, it can be analogous to the method mentioned above, where the temperature difference value and temperature difference change value of each target space are determined based on each temperature data set, and the sub-liquid supply temperature of each target space is determined based on the temperature difference value and temperature difference change value.

[0173] In one feasible implementation of this embodiment, when the environmental control system is in heating mode, the sub-target liquid supply temperature of the indoor terminal device in each target space is determined according to the indoor ambient temperature; the maximum temperature among at least two sub-target liquid supply temperatures is determined as the target liquid supply temperature.

[0174] In another feasible implementation of this embodiment, when the environmental control system is in cooling mode, the sub-target liquid supply temperature of the indoor terminal device in each target space is determined according to the indoor ambient temperature; the minimum temperature among at least two sub-target liquid supply temperatures is determined as the target liquid supply temperature.

[0175] In this embodiment, by means of the above method, it is ensured that the indoor terminal devices in each indoor space have sufficient heat supply, thereby effectively improving the comfort of each indoor space regulated by the environmental control system.

[0176] Furthermore, based on any of the above embodiments, in this embodiment, after the step of determining the indoor environmental parameters of the target space according to the state parameters and the operating scenario parameters, it further includes: when the environmental control system is in a preset control state, controlling the operation of the gas equipment according to the set liquid supply temperature; when the environmental control system is not in the preset control state, executing the step of determining the target liquid supply temperature of the gas equipment in the refrigerant circulation system according to the indoor environmental temperature, and controlling the operation of the gas equipment according to the target liquid supply temperature; wherein, the preset control state includes the target value of the liquid supply temperature of the gas equipment set in response to user instructions.

[0177] The liquid supply temperature set here is the target value for the liquid supply temperature of the gas equipment set by the user.

[0178] The preset control state can be understood as a control mode in which the user manually sets the refrigerant temperature.

[0179] In this embodiment, the above method helps to ensure that the heat supply of the gas equipment can be accurately matched with the user's needs.
