[0049] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0050] An embodiment of the present invention provides an environment adjustment device, which is specifically used to adjust the temperature of an indoor environment.

[0051] In the embodiment of the present invention, refer to Figure 1 and Figure 2 The environment conditioning device includes a heat pump system 2, a refrigerant circulation system 3 connected to the heat pump system 2, and a control device 1, wherein the heat pump system 2 and the refrigerant circulation system 3 are both connected to the control device 1. The refrigerant circulation system 3 transmits the energy output by the heat pump system to the indoor space through the circulation of the refrigerant to adjust the temperature of the indoor space. The heat pump system 2 is used to provide 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 brine circulation system 3 is a water system, the heat pump system 2 is used to adjust the water supply temperature of the brine circulation system 3, and the brine circulation system 3 can adjust the indoor temperature using the indoor terminal device 31. In the embodiment of the present invention, the water supply temperature of the brine circulation system 3 can be understood as the outlet water temperature of the heat pump system 2. In other embodiments, the brine circulation system 3 can also be a system that uses a brine to transmit 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.

[0054] The refrigerant circulation system 3 includes a medium circulation loop and an indoor terminal device 31 and a heat exchange module arranged 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 cold or heat of the refrigerant in the medium circulation loop can be released to the indoor space where it is located at the indoor terminal device 31.

[0055] There may be one or more indoor terminal devices 31, and more than one indoor terminal devices 31 may be distributed in different indoor spaces. The heat exchange types of the indoor terminal devices 31 in different indoor spaces may be the same or different. Based on this, the cold or heat carried by the medium in the medium circulation loop can be used to adjust the ambient temperature of more than one indoor space.

[0056] In this embodiment, the indoor terminal device 31 is a radiation terminal device, such as a radiation panel, a capillary network, etc. The radiation terminal device can be installed on the wall surface of the indoor space (including the wall surface and / or the ground, etc.). In other embodiments, the indoor terminal device 31 can also be a convection heat exchange device. For example, the indoor terminal device 31 may include a fan coil, a floor heating coil, a fan disc or a heat sink, etc.

[0057] 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, and the second heat exchanger is heat-exchange connected with the heat exchange module in the refrigerant circulation system 3. The second heat exchanger and the heat exchange module can be a shell and tube heat exchanger or a plate heat exchanger.

[0058] The heat pump system 2 can have two operating modes: cooling mode and heating mode. When the heat pump system 2 operates in cooling mode, the second heat exchanger is in an evaporating state to absorb heat. When the heat pump system 2 operates in heating mode, the second heat exchanger is in a condensing state to release heat.

[0059] During the operation of the heat pump system 2, the water in the heat exchange module can absorb the cold or heat released by the second heat exchanger to form cold water or hot water. The medium carrying cold or heat flowing out of the heat exchange module can enter the medium circulation loop and flow to the indoor terminal device 31 to release the cold or heat to the air in the indoor space to adjust the ambient temperature of the indoor space. The medium after releasing the cold or heat can re-enter the heat exchange module to exchange heat with the second heat exchanger, and the medium after heat exchange can re-enter the medium circulation loop to exchange heat, and so on, so as to realize the adjustment of the indoor space temperature by the environmental conditioning device.

[0060] When the heat pump system 2 is in cooling operation, the second heat exchanger is in an evaporating state. The medium in the heat exchange module absorbs the cold output by the second heat exchanger and its temperature decreases to form a medium that carries cold. The medium that carries cold enters the medium circulation loop and flows to the indoor terminal device 31, releasing cold to the indoor space, and the ambient temperature of the indoor space decreases.

[0061] When the heat pump system 2 is in heating operation, 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 indoor terminal device 31, releasing heat to the indoor space, and the ambient temperature of the indoor space rises.

[0062] Furthermore, the refrigerant circulation system 3 also includes a fluid regulating module 32, which is connected to the control device 1. The fluid regulating module 4 can be used to adjust the distribution, flow regulation and control of the supply and return liquid in the refrigerant circulation system 3. Specifically, the heat exchange module and the indoor terminal device 31 are both connected to the fluid regulating module 32. In this embodiment, the number of indoor terminal devices 31 is at least two, and at least two indoor terminal devices 31 and the heat exchange module are connected to the fluid regulating module 32. The fluid regulating module 32 includes at least two fluid valves, and the fluid valves are connected to the indoor terminal devices 31 in a one-to-one correspondence. In this embodiment, the fluid regulating module 4 is a manifold. In other embodiments, the fluid regulating module 32 may also be a circulating pump.

[0063] Further, in this embodiment, referring to Figure 2 The control device 1 can also be connected to the environment detection module 5, which may include an indoor temperature sensor and / or an outdoor temperature sensor. The indoor temperature sensor can detect the ambient temperature of the indoor space regulated by the environment conditioning device; the outdoor temperature sensor can detect the ambient temperature of the outdoor space where the environment conditioning device is located.

[0064] Further, in this embodiment, referring to Figure 2 The control device 1 may also be connected to a temperature sensor 6, which is disposed on the surface of the indoor terminal device to detect the surface temperature of the indoor terminal device.

[0065] In the embodiment of the present invention, refer to Figure 2 The control device 1 of the environment conditioning device includes: a processor 1001 (such as a CPU), a memory 1002, a timer 1003, etc. The various components in the control device 1 are connected via a communication bus. The memory 1002 can be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. The memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0066] Those skilled in the art will understand that Figure 2 The device structure shown in the figure does not constitute a limitation of the device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0067] like Figure 2 As shown, the memory 1002 as a storage medium may include a control program of the environment adjustment device. Figure 2 In the device shown, the processor 1001 can be used to call the control program of the environmental conditioning device stored in the memory 1002 and execute the relevant step operations of the control method of the environmental conditioning device in the following embodiments.

[0068] An embodiment of the present invention further provides a control method for an environmental conditioning device, which is applied to the above-mentioned environmental conditioning device.

[0069] Reference Figure 3 , an embodiment of a control method of an environmental conditioning device of the present application is proposed. In this embodiment, the control method of the environmental conditioning device includes:

[0070] Step S10, when the environment conditioning device is in a shutdown state or a standby state and the moisture-proof function is turned on, obtaining a first state parameter representing the condensation state of the indoor space;

[0071] The moisture-proof function is specifically a function for reducing the risk of condensation in indoor space. In this embodiment, the moisture-proof function is turned on in response to a user instruction. In other embodiments, the moisture-proof function can also be turned on when the environmental parameters or date, etc. are monitored to meet the set conditions.

[0072] The compressor stops when the environmental conditioning equipment is in the off state or in standby state.

[0073] The first state parameter may include environmental parameters of the indoor space and / or state parameters of the indoor terminal device and / or detection data of the wall surface of the indoor space, etc.

[0074] The first state parameter may include at least one of the following: indoor temperature data, indoor humidity data, indoor enthalpy data, surface temperature data of indoor terminal equipment, refrigerant temperature data related to the indoor terminal equipment, wall temperature of the indoor space, etc.

[0075] Step S20, when the first state parameter meets the condensation condition, the heat pump system is controlled to operate for heating, and the refrigerant circulation system is controlled to operate to transfer the heat of the heat pump system to the indoor terminal equipment in the indoor space.

[0076] The condensation condition is specifically a condition that the first state parameter needs to satisfy when the wall surface of the indoor space has a condensation risk. The condensation condition may include a target parameter interval that the first state parameter needs to reach or a target relationship with a preset parameter.

[0077] When the first state parameter meets the condensation condition, the environmental conditioning device can start the moisture-proof mode. In the moisture-proof mode, the heat pump system operates for heating while the refrigerant circulation system operates to transfer the heat of the heat pump system to the indoor terminal equipment in the indoor space with the risk of condensation.

[0078] When the refrigerant circulation system is in operation, in one implementation, the fluid regulating module in the refrigerant circulation system can be controlled to operate to regulate the amount of refrigerant flowing from the heat exchange module to the indoor terminal device. In another implementation, the convection regulating module (such as a fan, etc.) in the indoor terminal device of the refrigerant circulation system can be controlled to operate to regulate the amount of gas flowing through the indoor terminal device for heat exchange.

[0079] The operating parameters during the heating operation of the heat pump system and / or the operation of the refrigerant circulation system may be pre-set fixed parameters, or may be operating parameters determined according to the actual operating state of the environmental conditioning device. In the present embodiment, when the duration of the moisture-proof function being turned on is less than or equal to the preset duration, the preset refrigerant temperature is obtained as the initial target refrigerant temperature, and the heating operation of the heat pump system is controlled according to the initial target refrigerant temperature. In the present embodiment, the target refrigerant temperature is generally the outlet liquid temperature of the heat exchange module in the refrigerant circulation system. In other embodiments, the target refrigerant temperature may also be the temperature at other locations in the refrigerant circulation system, such as the inlet liquid temperature of the heat exchange module or the inlet liquid temperature of the indoor terminal device.

[0080] When the heat pump system is in heating operation, the second heat exchanger in the heat pump system is in a condensing state. When the refrigerant circulation system is in operation, 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 indoor terminal equipment. The heat released by the indoor terminal equipment can effectively increase the wall temperature of the indoor space.

[0081] A control method for an environmental conditioning device is proposed in an embodiment of the present invention. When the environmental conditioning device is in a shutdown state or a standby state and the moisture-proof function is turned on, when it is determined through a first state parameter that there is a risk of condensation indoors, no user operation is required. By controlling the heating operation of the heat pump system and controlling the refrigerant circulation system to transport the heat of the heat pump system to the indoor terminal device of the indoor space, the environmental conditioning device can automatically start the moisture-proof operation. During this process, the heat released by the indoor terminal device can effectively increase the wall temperature of the installed indoor space, prevent condensation on the wall of the indoor space, and effectively and timely reduce the risk of indoor moisture condensation.

[0082] Furthermore, in the above embodiment, the first state parameter includes the dew point temperature of the indoor space and the surface temperature of the indoor terminal device, and the condensation condition includes that the temperature difference between the surface temperature and the dew point temperature is less than a third preset temperature difference.

[0083] The dew point temperature can be calculated by detecting the indoor temperature and indoor humidity.

[0084] The surface temperature can be specifically detected by a temperature sensor arranged on the surface of the indoor terminal device.

[0085] In this embodiment, the third preset temperature difference is greater than 0 and the deviation from 0 is less than a preset value, such as 1 or 2 or 3 or 5.

[0086] Here, the temperature difference between the surface temperature and the dew point temperature can accurately reflect the risk of indoor condensation. If the temperature difference is less than the third preset temperature difference, it can accurately indicate the risk of indoor condensation. Therefore, based on the relationship between the temperature difference and the third preset temperature difference, precise control of the moisture-proof mode can be achieved to save energy while reducing the risk of indoor moisture condensation.

[0087] In other embodiments, the condensation condition may also include the surface temperature being less than or equal to the dew point temperature.

[0088] Further, based on the above embodiment, another embodiment of the control method of the environmental conditioning device of the present application is proposed. In this embodiment, referring to Figure 4 After controlling the heat pump system to operate in heating mode, the method further includes:

[0089] Step S21, obtaining a second state parameter representing the condensation state of the indoor space and / or a temperature state parameter of the surface of the indoor terminal device;

[0090] The second state parameter may include environmental parameters of the indoor space and / or state parameters of the indoor terminal device and / or detection data of the wall surface of the indoor space, etc.

[0091] The second state parameter may include at least one of the following: indoor temperature data, indoor humidity data, indoor enthalpy data, surface temperature data of indoor terminal equipment, refrigerant temperature data related to the indoor terminal equipment, wall temperature of the indoor space, etc.

[0092] The temperature state parameter may include at least one of the following: real-time temperature value, temperature change value, etc.

[0093] Step S22, determining a target brine temperature of the brine circulation system according to the second state parameter and / or the temperature state parameter;

[0094] The target brine temperature is specifically a target value of the brine in the brine circulation system.

[0095] Different second state parameters and / or different temperature state parameters correspond to different target coolant temperatures.

[0096] In one implementation, a correspondence between the second state parameter and / or the temperature state parameter and the target coolant temperature can be established in advance. The correspondence may include a calculation relationship, a mapping table, etc. Based on the correspondence, the target coolant temperature corresponding to the second state parameter and / or the temperature state parameter can be determined.

[0097] In another implementation, a correspondence between the second state parameter and / or the temperature state parameter and the temperature adjustment value may be established in advance. The correspondence may include a calculation relationship, a mapping table, etc. Based on the correspondence, the temperature adjustment value corresponding to the second state parameter and / or the temperature state parameter may be determined, and the target value of the current refrigerant in the refrigerant circulation system or the target value of the refrigerant preset in the refrigerant circulation system may be adjusted according to the temperature adjustment value to obtain the target refrigerant temperature.

[0098] In this embodiment, the target brine temperature is determined according to the second state parameter and the temperature state parameter.

[0099] Step S23, controlling the heating operation of the heat pump system according to the target refrigerant temperature.

[0100] In this embodiment, the outlet temperature of the heat exchange module is detected, and the control parameters of the heat pump system (such as frequency control parameters, control parameters of the throttling device, fan control parameters, etc.) are determined according to the outlet temperature and the target refrigerant temperature, and the heating operation of the heat pump system is controlled based on the determined control parameters. For example, the temperature difference between the outlet temperature and the target refrigerant temperature can be determined, and the target frequency of the compressor in the heat pump system can be determined according to the temperature difference, and the compressor is controlled to operate at the target frequency.

[0101] In this embodiment, controlling the heating operation of the heat pump system in the above manner is beneficial to improving the effectiveness of reducing the risk of condensation and ensuring indoor temperature comfort.

[0102] Furthermore, after step S23, a set time interval may be set and the process returns to step S21.

[0103] Furthermore, in this embodiment, the second state parameter includes the dew point temperature of the indoor space and the surface temperature of the indoor terminal device, and the temperature state parameter includes the surface temperature change value. Among them, the first surface temperature of the indoor terminal device at the current moment and the second surface temperature at the first moment before the current moment can be obtained, and the first moment and the current moment are separated by a preset time length, and the surface temperature change value here is determined according to the difference between the first surface temperature and the second surface temperature. Alternatively, the first surface temperature of the indoor terminal device at the current moment and the third surface temperature of the indoor terminal device at the moment when the heat pump system starts heating operation can be obtained, and the surface temperature change value here is determined according to the temperature difference between the first surface temperature and the third surface temperature.

[0104] The step of determining the target refrigerant temperature of the refrigerant circulation system according to the second state parameter and / or the temperature state parameter includes: when the temperature difference between the surface temperature and the dew point temperature is less than or equal to a first preset temperature difference, and the surface temperature change value is less than or equal to a first preset value, increasing the target value of the current refrigerant temperature of the refrigerant circulation system to obtain the target refrigerant temperature; when the surface temperature change value is greater than a second preset value, reducing the target value of the current refrigerant temperature of the refrigerant circulation system to obtain the target refrigerant temperature; wherein the second preset value is greater than or equal to the first preset value.

[0105] The first preset temperature difference is specifically a critical value for distinguishing whether the indoor condensation risk is high. The temperature difference between the surface temperature and the dew point temperature can be used as the condensation risk value. The smaller the condensation risk value, the greater the condensation risk. Based on this, when the condensation risk value is less than or equal to the first preset temperature difference, it can be considered that the indoor condensation risk is high at this time, and when the condensation risk value is greater than the first preset temperature difference, it can be considered that the indoor condensation risk is low at this time.

[0106] The first preset value and the second preset value are specifically pre-set critical values ​​for distinguishing the comfortable state of indoor space temperature. When the surface temperature change value is greater than the second preset value, it can be considered that the temperature rises greatly during the heating process, and the indoor space is prone to overheating and affects the comfort of indoor users; when the surface temperature change value is between the first preset value and the second preset value, it can be considered that the temperature rise is moderate during the heating process, and the indoor space is in a comfortable state for users; when the temperature change value is less than or equal to the first preset value, it can be considered that the indoor space is in a comfortable state for users during the heating process and may even be overcooled.

[0107] Here, the target value of the current coolant temperature may be a preset parameter value, or may be a parameter value obtained by adjusting the preset parameter value before the current moment.

[0108] The temperature adjustment value in the process of increasing or decreasing the target value may be a preset fixed value, such as 1°C. In addition, the temperature adjustment value in the process of increasing or decreasing the target value may also be determined according to the state parameters of the actual operation of the environmental conditioning device. For example, the temperature adjustment value here may be determined according to the surface temperature, dew point temperature, surface temperature change value, and the number of indoor spaces currently having condensation risks, and the target value of the current coolant temperature may be adjusted according to the determined temperature adjustment value to obtain the target coolant temperature.

[0109] In this embodiment, when the indoor condensation risk is high and the temperature does not rise too much, the heat output of the heat pump system is increased by increasing the target temperature of the refrigerant to further increase the surface temperature of the indoor terminal equipment, so as to effectively reduce the indoor condensation risk; when the indoor temperature rises by a large margin, it indicates that there is a risk of overheating in the indoor temperature. At this time, the heat output of the heat pump system is reduced by lowering the target temperature of the refrigerant to effectively ensure the comfort of indoor users. Based on this, it is possible to effectively balance reducing the indoor condensation risk and ensuring indoor comfort.

[0110] Furthermore, in this embodiment, before the step of obtaining the second state parameter representing the condensation state of the indoor space and / or the temperature state parameter of the surface of the indoor terminal device, it also includes: when the heat pump system starts heating operation, the preset refrigerant temperature is used as the target temperature of the refrigerant in the refrigerant circulation system to control the preset heating operation time of the heat pump system.

[0111] In this embodiment, the preset brine temperature may be the maximum brine temperature. In other embodiments, the preset brine temperature may also be a temperature lower than the maximum brine temperature.

[0112] The preset duration may be a pre-set fixed duration, or a duration determined according to the actual operation of the environmental conditioning device, for example, the preset duration here is determined according to the number of indoor spaces that meet the condensation conditions according to the first state parameter.

[0113] In this embodiment, when the heat pump system starts heating operation, the heat pump system is first controlled to heat for a period of time at a constant refrigerant temperature, and then the target refrigerant temperature is adjusted based on the above scheme, which is beneficial to improve the stability of system operation when heating is started.

[0114] Furthermore, in the present embodiment, after the step of determining the target refrigerant temperature of the refrigerant circulation system according to the second state parameter and / or the temperature state parameter, it also includes: when the target refrigerant temperature is within a preset temperature range, controlling the heating operation of the heat pump system according to the target refrigerant temperature; when the target refrigerant temperature is greater than the upper limit temperature of the preset temperature range, controlling the heating operation of the heat pump system with the upper limit temperature as the target temperature of the refrigerant; when the target refrigerant temperature is less than the lower limit temperature of the preset temperature range, controlling the heating operation of the heat pump system with the lower limit temperature as the target temperature of the refrigerant.

[0115] The preset temperature range here is specifically the pre-set coolant temperature range allowed for normal operation of the coolant circulation system. The upper limit temperature of the preset temperature range is the maximum coolant temperature allowed by the coolant circulation system, and the lower limit temperature of the preset temperature range is the minimum coolant temperature allowed by the coolant circulation system.

[0116] In this embodiment, through the above-mentioned method, it can be ensured that the target value of the refrigerant temperature used to control the operation of the heat pump system is within the preset temperature range, thereby ensuring the normal operation of the heat pump system.

[0117] Further, based on any of the above embodiments, another embodiment of the control method of the environmental conditioning device of the present application is proposed. Figure 5 , after step S20, further comprising:

[0118] Step S30, when the indoor space meets a preset condition, controlling the coolant circulation system to stop transferring heat from the heat pump system to the indoor terminal equipment in the indoor space;

[0119] The preset condition includes at least one of the following conditions:

[0120] The temperature difference between the surface temperature of the indoor terminal device and the dew point temperature of the indoor space is greater than a second preset temperature difference;

[0121] The temperature rise amplitude of the indoor space after the heat pump system is in heating operation is greater than the target amplitude.

[0122] The second preset temperature difference is greater than the first preset temperature difference mentioned above.

[0123] The second preset temperature difference is specifically a critical value for distinguishing whether the indoor space has a condensation risk. The temperature difference between the surface temperature and the dew point temperature can be used as a condensation risk value. The larger the condensation risk value, the smaller the condensation risk of the indoor space. Therefore, when the condensation risk value is greater than the second preset temperature difference, it can be considered that the indoor space does not have a condensation risk; when the condensation risk value is less than or equal to the second preset temperature difference, it can be considered that the indoor space has a condensation risk.

[0124] The first indoor temperature of the current indoor space and the second indoor temperature of the indoor space when the heat pump system starts heating operation are obtained, and the temperature rise range here is determined according to the temperature difference between the first indoor temperature and the second indoor temperature.

[0125] The target amplitude is specifically a critical value for distinguishing whether the indoor temperature is comfortable after the moisture-proof mode is started. The target amplitude can be a pre-set fixed value, or a value determined according to the actual operating conditions of the environmental conditioning device. In this embodiment, in order to accurately characterize indoor thermal comfort, the target amplitude includes the amplitude of the temperature rise of the outdoor environment corresponding to the environmental conditioning device after the heat pump system is running for heating. Specifically, the first outdoor temperature of the current outdoor environment and the second outdoor temperature of the outdoor environment when the heat pump system starts the heating operation are obtained, and the target amplitude here is determined according to the temperature difference between the first outdoor temperature and the second outdoor temperature.

[0126] In this embodiment, the preset condition may include that a temperature difference between the first indoor temperature and the second indoor temperature is greater than a temperature difference between the first outdoor temperature and the second outdoor temperature.

[0127] In this embodiment, the above-mentioned method can ensure that the indoor condensation risk is reduced while ensuring the indoor temperature comfort.

[0128] Further, based on any of the above embodiments, another embodiment of the control method of the environmental conditioning device of the present application is proposed. In this embodiment, the refrigerant circulation system includes at least two indoor terminal devices, and different indoor terminal devices are arranged in different indoor spaces. Figure 6 , step S20 comprises:

[0129] Step S201, when a first state parameter of at least one indoor space meets a condensation condition, controlling the heat pump system to operate for heating, controlling the refrigerant circulation system to operate to transfer heat from the heat pump system to an indoor terminal device in a first indoor space, and controlling the refrigerant circulation system to operate to stop transferring heat from the heat pump system to an indoor terminal device in a second indoor space;

[0130] The first indoor space is an indoor space whose first state parameter satisfies the condensation condition, and the second indoor space is an indoor space whose first state parameter does not satisfy the condensation condition.

[0131] For example, at least two indoor terminal devices are respectively arranged in room 1, room 2 and room 3. When the first state parameters corresponding to room 1 and room 2 meet the condensation conditions and the first state parameters of room 3 do not meet the condensation conditions, the refrigerant circulation system can be controlled to transfer heat to the indoor terminal devices in room 1 and room 2, and the refrigerant circulation system can be controlled to stop transferring heat to the indoor terminal device in room 3.

[0132] In this embodiment, through the above method, when the environmental conditioning equipment is used to adjust more than one indoor space, it can effectively reduce the condensation risk of the indoor space with condensation risk while avoiding affecting the environment of other spaces without condensation risk. It can save system energy consumption while achieving effective balance between moisture-proof effect and comfort of all indoor spaces.

[0133] Furthermore, in this embodiment, the refrigerant circulation system further includes a fluid regulating module, the fluid regulating module includes at least two fluid valves, the fluid valves are connected to the indoor terminal devices in a one-to-one correspondence, in this embodiment, the fluid regulating module is a manifold, and the fluid valve is a water diversion valve in the manifold. The steps of controlling the refrigerant circulation system to operate so as to transfer the heat of the heat pump system to the indoor terminal device in the first indoor space, and controlling the refrigerant circulation system to operate so as to stop transferring the heat of the heat pump system to the indoor terminal device in the second indoor space include:

[0134] The fluid valve corresponding to the first indoor space is controlled to be opened so that the coolant flows into the corresponding indoor terminal device, and the fluid valve corresponding to the second indoor space is controlled to be closed so that the coolant stops flowing into the corresponding indoor terminal device.

[0135] Based on this, differentiated and precise control of the inflow of refrigerant into different indoor terminal devices can be achieved through at least two fluid valves, thereby further saving system energy consumption while achieving an effective balance between moisture-proof effect and comfort in all indoor spaces.

[0136] Further, in this embodiment, the refrigerant circulation system includes at least two indoor terminal devices, different indoor terminal devices are arranged in different indoor spaces, and the first indoor space is defined as an indoor space in which the first state parameter satisfies the condensation condition. When the indoor space satisfies the preset condition, the step of controlling the refrigerant circulation system to stop transferring the heat of the heat pump system to the indoor terminal device in the indoor space includes:

[0137] When at least one of the first indoor spaces meets a preset condition, the refrigerant circulation system is controlled to stop transporting heat from the heat pump system to the indoor terminal equipment in the first indoor space that meets the preset condition.

[0138] Among them, while controlling the refrigerant circulation system to stop delivering heat from the heat pump system to the indoor terminal equipment in the first indoor space that meets the preset conditions, the refrigerant circulation system is controlled to maintain delivering heat from the heat pump system to the indoor terminal equipment in the first indoor space that does not meet the preset conditions.

[0139] When the fluid regulating module includes the at least two fluid valves mentioned above, when at least one of the first indoor spaces meets a preset condition, the fluid valve corresponding to the first indoor space meeting the preset condition is controlled to be closed.

[0140] In this embodiment, when the environmental conditioning device is used to regulate more than one indoor space and there is a risk of condensation in more than one indoor space, after the environmental conditioning device starts the moisture-proof mode, it can stop inputting energy to the corresponding indoor terminal device when the risk of condensation in the indoor space is eliminated or the temperature rises too high, thereby ensuring that the condensation risk reduction and comfort of each indoor space regulated by the environmental conditioning device are effectively balanced.

[0141] Furthermore, in the present embodiment, after the step of controlling the refrigerant circulation system to operate to stop transferring heat from the heat pump system to the indoor terminal equipment in the first indoor space that meets the preset conditions when at least one of the first indoor spaces meets the preset conditions, it also includes: when all the first indoor spaces meet the preset conditions, controlling the environmental conditioning equipment to shut down.

[0142] When the environmental conditioning equipment is shut down, both the heat pump system and the refrigerant circulation system are shut down.

[0143] Among them, when there is a first indoor space that does not meet the preset conditions, the process can return to the step of controlling the refrigerant circulation system to stop transferring heat from the heat pump system to the indoor terminal equipment in the first indoor space that meets the preset conditions when at least one of the first indoor spaces meets the preset conditions.

[0144] In this embodiment, the environmental conditioning equipment is shut down when all spaces with condensation risks meet preset conditions, thereby saving energy while further ensuring an effective balance between moisture-proofing and comfort in all indoor spaces.

[0145] In addition, an embodiment of the present invention further proposes a storage medium, on which a control program of an environmental conditioning device is stored. When the control program of the environmental conditioning device is executed by a processor, the relevant steps of any embodiment of the control method of the environmental conditioning device as described above are implemented.
