[0042] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0043] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0044] In this embodiment of the invention, reference is made to Figure 1 and Figure 2The environmental control equipment includes a control device 1 and a terminal group 31. The terminal group 31 includes at least two types of terminal devices, which are used to regulate the indoor space using the energy (cooling or heating) of the heat pump system 2. Different types of terminal devices exchange heat with the indoor space in different ways.

[0045] There may be one or more terminal groups 31, and more than one terminal group 31 may be distributed in different indoor spaces. The heat exchange types of the terminal groups 31 in different indoor spaces may be the same or different. In this embodiment, different types of terminal devices in the same terminal group 31 are connected in parallel. In other embodiments, different types of terminal devices in the same terminal group 31 may be connected in series.

[0046] In this embodiment, the terminal assembly 31 includes a radiant terminal device and a convective heat exchange device. The radiant terminal device may be a radiant panel, capillary network, underfloor heating coil, radiator, etc., and may be installed on the wall surface (including wall surface and / or floor and / or ceiling, etc.) of an indoor space. The convective heat exchange device may include a fan coil unit, etc.

[0047] In this embodiment, refer to Figure 1 The environmental control equipment includes a heat pump temperature control system 10 and a fresh air system 20. Both the heat pump temperature control system 10 and the fresh air system 20 are connected to the control device 1. The heat pump temperature control system 10 includes a heat pump system 2 and a refrigerant circulation system 3 connected to the heat pump system 2. Both the heat pump system 2 and the refrigerant circulation system 3 are connected to the control device 1.

[0048] The heat pump temperature control system 10 is used to regulate indoor ambient temperature and / or humidity. The fresh air system 20 is used to introduce fresh air and filter and purify it to improve indoor air quality.

[0049] The fresh air system 20 is used to regulate the air in more than one indoor space. In other embodiments, the fresh air system 20 can be used to regulate the air in one indoor space.

[0050] In this embodiment, the radiant terminal device and the convective heat exchange device are respectively located in the heat pump system 2 and the refrigerant circulation system 3. The heat pump system 2 includes the convective heat exchange device, and the refrigerant circulation system 3 includes the radiant terminal device.

[0051] The refrigerant circulation system 3 circulates the refrigerant, delivering the energy output from the heat pump system 2 to the indoor space to regulate its temperature. The heat pump system 2 provides energy (such as cooling or heating) for the heat exchange between the refrigerant circulation system 3 and the indoor space.

[0052] In this embodiment, the refrigerant circulation system 3 is a water system, and the heat pump system 2 is used to regulate the supply water temperature of the refrigerant circulation system 3. The refrigerant circulation system 3 can utilize terminal devices to regulate the indoor temperature. In this embodiment, the supply water temperature of the refrigerant circulation system 3 can be understood as the outlet water temperature of the heat pump system 2. In other embodiments, the refrigerant circulation system 3 can also be a system that uses a refrigerant to transfer energy, such as an ethanol solution.

[0053] In this embodiment, the heat pump system 2 is an air source heat pump system 2. In other embodiments, the heat pump system 2 may also be a water source heat pump system, a ground source heat pump system, or a dual-source heat pump system, etc.

[0054] The refrigerant circulation system 3 includes a medium circulation loop and terminal equipment and a heat exchange module located in the medium circulation loop. The heat exchange module is connected to the heat pump system 2 for heat exchange. The medium circulation loop has an inlet and an outlet. The inlet of the medium circulation loop is connected to the outlet of the heat exchange module, and the outlet of the medium circulation loop is connected to the inlet of the heat exchange module. The cooling or heating capacity of the refrigerant in the medium circulation loop can be released into the indoor space where it is located.

[0055] In this embodiment, the heat pump system 2 includes a refrigerant circulation loop, which includes a compressor, a first heat exchanger, a throttling device, and a second heat exchanger. The second heat exchanger is connected to the heat exchange module in the refrigerant circulation system 3 for heat exchange, and is connected in parallel with the terminal equipment in the heat pump system 2. The second heat exchanger and the heat exchange module can be a shell-and-tube heat exchanger or a plate heat exchanger.

[0056] The heat pump system 2 can operate in two modes: cooling mode and heating mode. When the heat pump system 2 is operating in cooling mode, the second heat exchanger is in an evaporating state to absorb heat, and when the heat pump system 2 is operating in heating mode, the second heat exchanger is in a condensing state to release heat.

[0057] During the operation of heat pump system 2, the water in the heat exchange module absorbs the cold or heat released by the second heat exchanger to form chilled or hot water. The medium carrying the cold or heat flowing out of the heat exchange module can enter the medium circulation loop and flow to the terminal equipment to release the cold or heat into the indoor air, thereby regulating the ambient temperature of the indoor space. After releasing the cold or heat, the medium can re-enter the heat exchange module to exchange heat with the second heat exchanger, and then re-enter the medium circulation loop for heat exchange. This cycle continues, thereby achieving the regulation of the indoor space temperature by the heat pump temperature control system.

[0058] When the heat pump system 2 is running in cooling mode, the second heat exchanger is in an evaporation state. The medium in the heat exchange module absorbs the cold energy output by the second heat exchanger and its temperature decreases to form a medium carrying the cold energy. The medium carrying the cold energy enters the medium circulation loop and flows to the terminal equipment, releasing the cold energy into the indoor space, and the ambient temperature of the indoor space decreases.

[0059] When the heat pump system 2 is in heating mode, the second heat exchanger is in a condensing state. The medium in the heat exchange module absorbs the heat output by the second heat exchanger and its temperature rises to form a heat-carrying medium. The heat-carrying medium enters the medium circulation loop and flows to the terminal equipment, releasing heat into the indoor space and raising the ambient temperature of the indoor space.

[0060] In other embodiments, the heat pump temperature control system may not have a refrigerant circulation system 3, and the terminal group 31 may be built into the heat pump system 2. The radiant terminal device and the convective heat exchange device are both located in the refrigerant circulation system 3.

[0061] Furthermore, refer to Figure 1 The refrigerant circulation system 3 also includes a fluid regulation module 32, which is connected to the control device 1. The fluid regulation module 32 can be used to regulate the distribution, flow rate regulation, and control of the supply and return liquid in the refrigerant circulation system 3. Specifically, the heat exchange module and the terminal group 31 are both connected to the fluid regulation module 32. In this embodiment, there are at least two terminal groups 31, and both the at least two terminal groups 31 and the heat exchange module are connected to the fluid regulation module 32. The fluid regulation module 32 includes at least two control valves, which are connected one-to-one with the terminal groups 31. In this embodiment, the fluid regulation module is a water distribution manifold. In other embodiments, the fluid regulation module 32 can also be a circulation pump.

[0062] In this embodiment of the invention, the fresh air system 20 includes a fresh air duct, an exhaust air duct, and a heat pump subsystem. The heat pump subsystem includes a compressor, a third heat exchanger, a throttling device, and a fourth heat exchanger. The third and fourth heat exchangers are respectively connected to the exhaust port and the return port of the compressor. The third heat exchanger, the throttling device, and the fourth heat exchanger are connected in sequence.

[0063] Fresh air ducts and exhaust air ducts can be equipped with separate fans. When the fan in the fresh air duct is turned on, it can drive fresh outdoor air into the room, and when the fan in the exhaust air duct is turned on, it can drive indoor air out to the outside.

[0064] The third and / or fourth heat exchangers can be installed in the fresh air duct to regulate the temperature and / or humidity of the fresh air.

[0065] One of the third and fourth heat exchangers can be installed in the exhaust duct to recover and utilize the energy in the exhaust air.

[0066] Furthermore, there may be more than one heat pump subsystem, with the third and / or fourth heat exchangers in different heat pump subsystems arranged along the airflow direction in the fresh air duct.

[0067] In other embodiments, the fresh air system 20 may also not include an exhaust duct and / or a heat pump subsystem.

[0068] Furthermore, when the fresh air system 20 is used to regulate more than one indoor space, the fresh air system 20 may also include more than one valve assembly, with each valve assembly corresponding to a specific indoor space. The valve assembly can be used to regulate the flow of air between the corresponding indoor space and the outdoor environment. When the valve assembly is open, outdoor fresh air can enter the corresponding indoor space, and the air in the corresponding indoor space can be exhausted outdoors; when the valve assembly is closed, outdoor fresh air stops entering the corresponding indoor space, and the air in the corresponding indoor space stops being exhausted outdoors.

[0069] Furthermore, in this embodiment, referring to Figure 2 The control device 1 can also be connected to the environmental detection module 5. The environmental detection module 5 can include indoor sensors and / or outdoor sensors. The indoor sensors can detect the environmental parameters (temperature, humidity, enthalpy, etc.) of the indoor space regulated by the environmental control equipment; the outdoor temperature sensor can detect the environmental parameters (temperature, humidity, enthalpy, etc.) of the outdoor space where it is located.

[0070] Furthermore, in this embodiment, referring to Figure 2 The control device 1 can also be connected to the temperature sensor 4, which is located on the outlet side of the heat exchange module to detect the outlet temperature of the heat exchange module.

[0071] In this embodiment of the invention, reference is made to Figure 2 The control device 1 of the environmental control equipment includes: a processor 1001, such as a CPU, a memory 1002, and a timer 1003. These components communicate with each other via a communication bus. The memory 1002 can be a high-speed RAM or a stable, non-volatile memory, such as a disk drive. Optionally, the memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0072] Those skilled in the art will understand that Figure 1 The device structure shown does not constitute a limitation on the device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0073] like Figure 2 As shown, the memory 1002, which serves as a computer storage medium, may include a control program for an environmental control device.

[0074] exist Figure 2 In the device shown, the processor 1001 can be used to call the control program of the environmental control device stored in the memory 1002 and execute the relevant steps of the control method of the environmental control device in the following embodiments.

[0075] This invention also provides a control method for an environmental control device, which is applied to the aforementioned environmental control device.

[0076] Reference Figure 3 This application proposes an embodiment of a control method for an environmental conditioning device. In this embodiment, the control method for the environmental conditioning device includes:

[0077] Step S10: When the environmental conditioning device is in heat exchange mode and meets the preset conditions, the first ambient temperature of the indoor space regulated by the terminal group is obtained, and the preset conditions indicate that there is a user in the indoor space;

[0078] The heat exchange mode includes either a cooling mode or a heating mode. In this embodiment, the heat exchange mode is a heating mode, in which the terminal device is in a heating state.

[0079] The environmental control equipment can be considered to meet the preset conditions when it operates under at least one of the following conditions: receiving a user's instruction to be in the indoor space, the current time of the air conditioner reaching the user's set time to enter the indoor space, the presence of human characteristic information in the environmental detection parameters of the indoor space, etc.

[0080] Furthermore, the preset conditions indicate the current moment when the user enters the indoor space.

[0081] The radiant terminal devices and convective heat exchange devices in the terminal group are all located in the same indoor space. The initial ambient temperature can be monitored in real time by an environmental monitoring module located in the indoor space.

[0082] Step S20: When the first ambient temperature meets the first condition, control both the radiant terminal device and the convective heat exchange device to turn on; wherein, the first condition indicates that the indoor environment deviates from a comfortable state.

[0083] The first condition may include the target temperature range that the first ambient temperature needs to reach when the indoor environment deviates from the comfort state, and / or the first condition may include the target quantitative relationship between the first ambient temperature and the reference temperature when the indoor environment deviates from the comfort state, etc.

[0084] The operating parameters when the radiant terminal device is turned on (e.g., refrigerant flow rate and / or radiant surface temperature) and / or the operating parameters when the convection terminal device is turned on (e.g., heat exchanger temperature and / or fan speed and / or refrigerant flow rate) can be preset fixed parameters, or they can be determined according to the actual operating conditions of the environmental control equipment. For example, the operating parameters when the radiant terminal device and the convection terminal device are turned on can be determined according to the temperature difference between the first ambient temperature and the set temperature and / or the temperature of the refrigerant flowing out of the heat exchange module and / or the relationship between the temperature of the radiant terminal device and the temperature of the convection terminal device.

[0085] Controlling the radiant terminal device's activation can include maintaining it in an on state or switching it from an off state to an on state. When the environmental control equipment is in heat exchange mode and meets preset conditions, the radiant terminal device can be activated first, while the convection heat exchange device is maintained in its initial off state. A first ambient temperature is acquired when the radiant terminal device is on. When the first ambient temperature meets a first condition, the radiant terminal device is activated, and the convection heat exchange device is activated. Furthermore, the environmental control equipment can include at least two terminal groups, each corresponding to the regulation of an indoor space. The first ambient temperature of the indoor space regulated by each terminal group can then be acquired. Each terminal group can then regulate according to its corresponding...

[0086] When the first ambient temperature meets the first condition, both the corresponding radiant terminal device and the convective heat exchange device are turned on; when the first ambient temperature does not meet the first condition, the corresponding radiant terminal device is turned on and the corresponding convective heat exchange device is turned off.

[0087] This invention proposes a control method for an environmental conditioning device. The device includes a radiant terminal unit and a convective heat exchanger to regulate the same indoor space. When the environmental conditioning device is in heat exchange mode, if the indoor environment deviates from a comfortable state based on a first ambient temperature, both the radiant terminal unit and the convective heat exchanger are activated. By simultaneously using both devices to exchange heat, the rapid heat exchange of the convective heat exchanger compensates for the thermal lag problem of the radiant terminal unit, effectively improving the heat exchange efficiency of the environmental conditioning device and thus enhancing user comfort.

[0088] Furthermore, in the above embodiments, in the heat exchange mode, the terminal group is in a heating state, and the first condition includes at least one of the following:

[0089] Condition 1: The first ambient temperature is lower than the first preset temperature;

[0090] Condition 2: The temperature difference between the first ambient temperature and the set temperature of the terminal group is less than the first preset temperature difference.

[0091] The set temperature here is the target temperature that the indoor space needs to reach under the pre-set adjustment of the terminal group. The first preset temperature difference is less than 0.

[0092] The first preset temperature and / or the first preset temperature difference can be fixed values ​​set in advance, or values ​​determined based on the actual operating conditions of the environmental control equipment. In this embodiment, the range of the first preset temperature is [16℃, 18℃], and the range of the first preset temperature difference is [-3℃, -0.5℃].

[0093] Furthermore, in this embodiment, condition 1 includes a first ambient temperature lower than a first preset temperature and a duration greater than a set duration, and condition 2 includes a temperature difference between the first ambient temperature and the set temperature of the terminal group being less than a first preset temperature difference and a duration greater than a set duration. The set duration here ranges from [2 min, 10 min].

[0094] In this embodiment, if the indoor ambient temperature is too low or the temperature difference between the indoor ambient temperature and the set temperature is too small, it indicates that the indoor temperature is very cold and deviates from the user's comfort state. At this time, using both the radiant terminal device and the convection heat exchange device for heating is beneficial to effectively improve the heating efficiency of the indoor space and effectively improve the thermal comfort of the indoor user.

[0095] In other embodiments, the terminal group is in a cooling state in the heat exchange mode, and the first condition may also include at least one of the following: the first ambient temperature is greater than the preset temperature, and the temperature difference between the first ambient temperature and the set temperature of the terminal group is greater than the preset temperature difference.

[0096] Furthermore, based on the above embodiments, another embodiment of the control method for the environmental conditioning equipment of this application is proposed. In this embodiment, the terminal group in the heat exchange mode is in a heating state, referring to... Figure 4 After the step of controlling both the radiant terminal device and the convective heat exchange device to turn on when the first ambient temperature meets the first condition, the method further includes:

[0097] Step S30: When the environmental conditioning equipment operates to the point where the second condition is met, control the convection heat exchange device to shut down;

[0098] The second condition includes either a first sub-condition or a second sub-condition. The first sub-condition includes that the operating time of the convection heat exchange device is greater than a preset time. The second sub-condition includes at least one of the following: the ambient temperature of the indoor space regulated by the terminal group is greater than a second preset temperature, and the temperature difference between the ambient temperature of the indoor space regulated by the terminal group and the corresponding set temperature is greater than a second preset temperature difference.

[0099] When the environmental control equipment operates to the point where the second condition is met, the convective heat exchange device is shut down while the radiant terminal device maintains its current heating state.

[0100] At least one of the preset duration, the second preset temperature, and the second preset temperature difference can be a pre-set fixed parameter, or a parameter determined according to the actual operating conditions of the environmental control equipment. In this embodiment, the preset duration ranges from [15 min to 120 min], and the second preset temperature ranges from [25°C to 35°C].

[0101] The preset duration is the duration for which the convection heat exchanger is turned on to meet the user's comfort requirements. To avoid cold air blowing on people, the initial value of the preset duration is generally set to a small value.

[0102] The second sub-condition indicates that the indoor environment deviates little from the user's comfort level.

[0103] In this embodiment, the convection heat exchanger is turned off when the indoor ambient temperature is close to the user's comfort temperature, which helps to improve the airflow comfort of the indoor user; the convection heat exchanger is turned off when the running time reaches the preset time, which helps to avoid the convection heat exchanger affecting the airflow comfort of the indoor user during the air supply process.

[0104] Furthermore, in this embodiment, after the step of controlling the convective heat exchange device to shut down when the environmental conditioning equipment operates to the point of meeting the second condition, the method further includes:

[0105] When the convection heat exchange device is turned off, if the environmental control equipment meets the first sub-condition but does not meet the second sub-condition, the preset duration and / or the second preset temperature difference and / or the second preset temperature shall be increased.

[0106] Return to the step of obtaining the first ambient temperature of the indoor space regulated by the terminal group.

[0107] The preset duration and / or the second preset temperature difference and / or the second preset temperature adjustment parameters can be fixed adjustment parameters set in advance, or parameters determined according to the actual operating conditions of the environmental control equipment.

[0108] In this embodiment, when the indoor ambient temperature deviates significantly from the comfort state and the convection heat exchanger shuts down due to excessive operation time, the ambient temperature of the indoor space is re-detected after a preset time is increased to determine whether the ambient temperature meets the first condition. This helps to extend the duration of the convection heat exchanger's next start-up, ensuring that the ambient temperature of the indoor space is as close as possible to the user's comfort state when the convection heat exchanger is shut down. This ensures the user's comfort while reducing the frequent opening and closing of the convection heat exchanger, improving the operational stability of the convection heat exchanger and enhancing the user's comfort.

[0109] Furthermore, in this embodiment, the environmental conditioning device includes a heat pump system and a refrigerant circulation system. The refrigerant circulation system includes a heat exchange module connected to the heat pump system. The radiant terminal device and the convective heat exchange device are respectively located in the heat pump system and the refrigerant circulation system, or both the radiant terminal device and the convective heat exchange device are located in the refrigerant circulation system. Before the step of increasing the preset duration and / or the second preset temperature difference and / or the second preset temperature, the method further includes: when the environmental conditioning device satisfies the first sub-condition but not the second sub-condition when the convective heat exchange device is closed, obtaining the change value of the outlet liquid temperature of the heat exchange module when both the convective heat exchange device and the radiant terminal device are open; determining adjustment parameters based on the change value of the outlet liquid temperature; the step of increasing the preset duration and / or the second preset temperature difference and / or the second preset temperature includes: increasing the preset duration and / or the second preset temperature difference and / or the second preset temperature based on the adjustment parameters.

[0110] Among them, the change in liquid outlet temperature is detected during the operation of the heat pump system with fixed operating parameters, which can indicate the change in the heat supply of the heat pump system when the radiant terminal device and the convective heat exchange device are turned on at the same time.

[0111] The adjustment parameters may include a duration adjustment parameter corresponding to a preset duration and / or a temperature difference adjustment parameter corresponding to a second preset temperature and / or a temperature adjustment parameter corresponding to a second preset temperature. In this embodiment, the value range of the duration adjustment parameter is [5min, 30min].

[0112] Different outlet temperature changes correspond to different adjustment parameters. For example, the duration adjustment parameter is positively correlated with the outlet temperature. In this embodiment, the correspondence between the outlet temperature change and the adjustment parameter can be preset. The correspondence can include calculation formulas, mapping tables, etc., and the adjustment parameter corresponding to the outlet temperature change can be determined based on this correspondence. Furthermore, more than one correspondence can be preset. A target correspondence can be determined from more than one correspondence based on the ambient temperature of the indoor space when the convection heat exchanger is turned off, and the adjustment parameter corresponding to the outlet temperature change is determined based on the target correspondence.

[0113] In this embodiment, the above method helps to avoid insufficient heat supply from the heat pump system when the radiant terminal device and the convection heat exchange device are turned on at the same time, thereby ensuring the temperature comfort and wind comfort of indoor users, reducing the frequent start-up and shutdown of the convection heat exchange device, and improving the heat exchange efficiency of the equipment.

[0114] Furthermore, based on any of the above embodiments, another embodiment of the control method for the environmental conditioning equipment of this application is proposed. In this embodiment, reference is made to... Figure 5After the step of obtaining the first ambient temperature of the indoor space regulated by the terminal group, the method further includes:

[0115] Step S40: When the first ambient temperature does not meet the first condition, control the radiant terminal device to turn on and control the convective heat exchange device to turn off.

[0116] Controlling the activation of the radiant terminal device may include controlling the radiant terminal device to remain on or to switch from a closed state to an on state.

[0117] In this embodiment, the first ambient temperature does not meet the first condition, indicating that the temperature state of the indoor space deviates from the user's comfort state by a small degree. At this time, using a radiant terminal device to heat the room alone is beneficial to the absence of wind during the heating process, ensuring the temperature comfort of the indoor user while improving the wind comfort of the indoor user during the heating process.

[0118] Furthermore, in this embodiment, the environmental conditioning equipment includes a heat pump system and a refrigerant circulation system that exchanges heat with the heat pump system. The radiant terminal device and the convective heat exchange device are respectively located in the heat pump system and the refrigerant circulation system, or both the radiant terminal device and the convective heat exchange device are located in the refrigerant circulation system. After step S40, the method further includes: obtaining a third ambient temperature of the indoor space regulated by the terminal group; determining a second target refrigerant temperature of the refrigerant circulation system based on the third ambient temperature and the set temperature of the terminal group; and controlling the operation of the environmental conditioning equipment based on the second target refrigerant temperature.

[0119] The specific ambient temperature can be obtained by acquiring the temperature data in real time from the environmental monitoring module installed in the indoor space.

[0120] In this embodiment, the temperature difference between the third ambient temperature and the set temperature is determined, and the second target refrigerant temperature is determined based on the temperature difference. In the heat exchange mode, when the terminal unit is in heating mode, if the temperature difference is less than the first preset value, the target value of the current refrigerant temperature in the refrigerant circulation system is increased to obtain the second target refrigerant temperature; if the temperature difference is greater than or equal to the second preset value, the target value of the current refrigerant temperature in the refrigerant circulation system is decreased to obtain the second target refrigerant temperature, where the second preset value is greater than or equal to the first preset value. The target value of the current refrigerant temperature can be a preset initial temperature or the second target refrigerant temperature obtained before the current time after adjusting the initial temperature to adapt to the temperature difference.

[0121] The operation of the heat pump system and / or the refrigerant circulation system is controlled according to the second target refrigerant temperature. The controlled objects include, but are not limited to, at least one of the following: the operating frequency of the compressor in the heat pump system, the opening degree of the electronic expansion valve in the heat pump system, the speed of the fan corresponding to the heat exchanger in the heat pump system, the operating parameters of the fluid regulation module in the refrigerant circulation system, etc.

[0122] Specifically, the current refrigerant temperature in the refrigerant circulation system can be obtained, and the operation of the heat pump system and / or the refrigerant circulation system can be controlled based on the temperature difference between the current refrigerant temperature and the second target refrigerant temperature.

[0123] In this embodiment, it is beneficial to ensure that the heat exchange capacity of the terminal unit is accurately matched with the actual heat exchange demand of the indoor space, thereby further improving user comfort.

[0124] Furthermore, based on any of the above embodiments, another embodiment of the control method for the environmental conditioning equipment of this application is proposed. In this embodiment, the environmental conditioning equipment includes a heat pump system and a refrigerant circulation system that exchanges heat with the heat pump system. The radiant terminal device and the convective heat exchange device are respectively disposed in the heat pump system and the refrigerant circulation system, or the radiant terminal device and the convective heat exchange device are both disposed in the refrigerant circulation system, as described above. Figure 6 After step S20, the following steps are also included:

[0125] Step S50: Obtain the second ambient temperature of the indoor space regulated by the terminal group;

[0126] The specific ambient temperature can be obtained by acquiring the temperature data detected in real time by the environmental monitoring module located in the indoor space.

[0127] Step S60: Determine the first target refrigerant temperature of the refrigerant circulation system based on the second ambient temperature and the set temperature of the terminal group;

[0128] The refrigerant circulation system also includes a heat exchange module connected to the heat pump system, and the first target refrigerant temperature is the target temperature at which the refrigerant flows out of the heat exchange module.

[0129] In this embodiment, the temperature difference between the second ambient temperature and the set temperature is determined, and the first target refrigerant temperature is determined based on the temperature difference. In the heat exchange mode, when the terminal unit is in heating mode, if the temperature difference is less than a first preset value, the target value of the current refrigerant temperature in the refrigerant circulation system is increased to obtain the first target refrigerant temperature; if the temperature difference is greater than or equal to a second preset value, the target value of the current refrigerant temperature in the refrigerant circulation system is decreased to obtain the first target refrigerant temperature, where the second preset value is greater than or equal to the first preset value. The target value of the current refrigerant temperature can be a preset initial temperature or the first target refrigerant temperature obtained before the current time after adjusting the initial temperature to adapt to the temperature difference.

[0130] Step S70: Control the operation of the environmental conditioning equipment according to the first target refrigerant temperature.

[0131] The operation of the heat pump system and / or the refrigerant circulation system is controlled according to the first target refrigerant temperature. The controlled objects include, but are not limited to, at least one of the following: the operating frequency of the compressor in the heat pump system, the opening degree of the electronic expansion valve in the heat pump system, the speed of the fan corresponding to the heat exchanger in the heat pump system, the operating parameters of the fluid regulation module in the refrigerant circulation system, etc.

[0132] Specifically, the current refrigerant temperature in the refrigerant circulation system can be obtained, and the operation of the heat pump system and / or the refrigerant circulation system can be controlled based on the temperature difference between the current refrigerant temperature and the first target refrigerant temperature.

[0133] In this embodiment, it is beneficial to ensure that the heat exchange capacity of the terminal unit is accurately matched with the actual heat exchange demand of the indoor space, thereby further improving user comfort.
