[0055] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0056] An embodiment of the present application provides an environmental conditioning device for conditioning the air in an indoor environment.

[0057] 1 and 2 , the environment conditioning device includes a control device 1 , a heat pump system 2 , and a brine circulation system 3 . The heat pump system 2 and the brine circulation system 3 are both connected to the control device 1 .

[0058] In one embodiment, the brine circulation system 3 is a water system, which can adjust the indoor temperature using the indoor terminal device 31. 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.

[0059] In one embodiment, the refrigerant circulation system 3 includes a medium circulation loop and a liquid supply module 4. The medium circulation loop includes an energy supply module and at least two types of indoor terminal devices 31. The liquid inlet of the indoor terminal device is connected to the liquid supply module 4. The liquid outlet of the energy supply module is connected to the indoor terminal device 31 and the liquid supply module 4.

[0060] The number of each type of indoor terminal device 31 in the at least two types of indoor terminal devices 31 can be one or more. The at least two types of indoor terminal devices 31 can be distributed and installed in different indoor spaces. Alternatively, the at least two types of indoor terminal devices 31 can be installed in different areas of the same indoor space.

[0061] In one embodiment, at least two types of indoor terminal devices 31 are connected in parallel to the energy supply module. In other embodiments, at least two types of indoor terminal devices 31 can be connected in series to the energy supply module.

[0062] In one embodiment, at least two indoor terminal devices 31 of the same type are connected in parallel to the energy supply module. In other embodiments, at least two indoor terminal devices 31 of the same type may be connected in series to the energy supply module.

[0063] In one embodiment, at least two types of indoor terminal devices 31 include a first type terminal and a second type terminal. For example, the first type terminal is a radiation terminal device (e.g., a radiant panel, a capillary network, etc.), and the second type terminal is a convective heat exchange device (e.g., a fan coil unit, etc.). The radiation terminal device can be installed on a wall surface (including a wall and / or floor, etc.) of the indoor space.

[0064] The energy supply module is used to provide cooling or heating to the refrigerant flowing through it. The energy supply module can be a module that stores energy, such as an energy storage tank. It can also be a heat exchange module that is connected to other energy-generating systems for heat exchange. It can also be a module that generates heat itself, such as an electric heating module.

[0065] The liquid inlet of each indoor terminal device 31 is connected to the liquid outlet of the energy supply module, and the liquid outlet of each indoor terminal device 31 is connected to the liquid inlet of the energy supply module. A refrigerant can circulate between the indoor terminal devices 31 and the energy supply module. As the refrigerant flows through the energy supply module, it absorbs the cooling or heat from the energy supply module and releases it to the indoor space where the indoor terminal device 31 is located.

[0066] In the at least two types of indoor terminal devices 31, the liquid inlet of the first type of terminal is connected to the liquid outlet of the liquid supply module 4. In one embodiment, the at least two types of indoor terminal devices 31 include radiation terminal devices and other types of devices, and the liquid outlet of the liquid supply module 4 can be connected to the liquid inlet of the radiation terminal device.

[0067] In one embodiment, the heat pump system 2 is an air source heat pump system. 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.

[0068] In one embodiment, the heat pump system 2 includes a refrigerant circulation circuit, which includes a compressor, a first heat exchanger, a throttling device, and a second heat exchanger. The second heat exchanger is heat-exchangeably connected to the energy supply module in the refrigerant circulation system 3. The second heat exchanger and the energy supply module can be a shell-and-tube heat exchanger or a plate heat exchanger.

[0069] 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 and absorbs heat. When the heat pump system 2 operates in heating mode, the second heat exchanger is in a condensing state and releases heat.

[0070] During operation of heat pump system 2, the refrigerant in the energy supply module absorbs the cooling or heat released by the second heat exchanger. The cooling or heat-carrying refrigerant flowing out of the energy supply module can flow through the medium circulation loop to the indoor terminal device 31, where it releases the cooling or heat into the air in the indoor space, thereby regulating the ambient temperature of the indoor space. After releasing the cooling or heat, the refrigerant can re-enter the energy supply module to exchange heat with the second heat exchanger. After heat exchange, the refrigerant can re-enter the medium circulation loop for heat exchange, and this cycle continues, thereby enabling the environmental conditioning device to regulate the indoor temperature.

[0071] When the heat pump system 2 is in cooling operation, the second heat exchanger is in an evaporating state. The refrigerant in the energy supply module absorbs the cold output by the second heat exchanger and its temperature drops to form a refrigerant carrying cold. The refrigerant carrying 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 drops.

[0072] When the heat pump system 2 is in heating operation, the second heat exchanger is in a condensing state. The refrigerant in the energy supply module absorbs the heat output by the second heat exchanger and its temperature rises to form a refrigerant carrying heat. The refrigerant carrying heat 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.

[0073] The liquid supply module 4 is specifically a module that can be used to input the brine to the indoor terminal device 31. For example, the liquid supply module 4 includes at least two solenoid valves, a three-way valve, a water mixing proportional valve, and the like.

[0074] In one embodiment, the pipeline between the liquid outlet of the indoor terminal device 31 and the liquid inlet of the energy supply module is connected to the liquid inlet of the liquid supply module 4. The liquid outlet of the first type of terminal and / or the liquid outlet of the second type of terminal are connected to the liquid inlet of the liquid supply module 4. The liquid outlet of the radiation terminal device is connected to the liquid inlet of the liquid supply module 4. In other embodiments, the liquid outlets of other terminal devices may also be connected to the liquid inlet of the liquid supply module 4.

[0075] In other embodiments, the liquid inlet of the liquid supply module 4 may also be connected to other modules other than the brine circulation system 3 that can provide brine.

[0076] The liquid supply module 4 can be turned on or off or the liquid output flow rate can be adjusted under the control of the control device 1. When the liquid supply module 4 is turned on, it can supply liquid to the indoor terminal device 31 connected to it; when the liquid supply module 4 is turned off, it can stop supplying liquid to the indoor terminal device 31 connected to it. Specifically, when the temperature of the refrigerant output by the liquid supply module 4 is greater than the temperature of the refrigerant flowing out of the energy supply module, the liquid supply module 4 can increase the temperature of the refrigerant flowing into the indoor terminal device 31 connected to it when it is turned on; when the temperature of the refrigerant output by the liquid supply module 4 is less than the temperature of the refrigerant flowing out of the energy supply module, the liquid supply module 4 can decrease the temperature of the refrigerant flowing into the indoor terminal device 31 connected to it when it is turned on.

[0077] In one embodiment, the pipeline between the liquid outlet of the energy supply module and the radiation terminal device is connected to the liquid outlet of the energy supply module. When the energy supply module operates in the first state, the liquid outlet of the energy supply module and the liquid outlet of the liquid supply module 4 are both connected to the liquid inlet of the radiation terminal device. Then, the refrigerant flowing out of the energy supply module can be mixed with the refrigerant flowing out of the liquid supply module 4 and then flow into the radiation terminal device. At this time, the temperature of the refrigerant flowing into the radiation terminal device is greater than or less than the temperature of the refrigerant flowing out of the energy supply module; when the energy supply module operates in the second state, the liquid outlet of the energy supply module is connected to the liquid inlet of the radiation terminal device, the liquid outlet of the liquid supply module 4 is connected to the liquid inlet of the radiation terminal device, and the liquid inlet of the radiation terminal device and the liquid outlet of the energy supply module are both blocked from the liquid outlet of the liquid supply module 4. At this time, the temperature of the refrigerant flowing into the radiation terminal device is equal to the temperature of the refrigerant flowing out of the energy supply module.

[0078] In one embodiment, the refrigerant circulation system 3 further includes a fluid regulating module, which is connected to the control device 1. The fluid regulating module 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 energy supply module and the indoor terminal device 31 are both connected to the fluid regulating module. In one embodiment, the number of indoor terminal devices 31 is at least two, and at least two indoor terminal devices 31 and the energy supply module are both connected to the fluid regulating module. The fluid regulating module includes at least two fluid valves, which are connected to the indoor terminal devices 31 in a one-to-one correspondence. The fluid valves are used to control the flow rate of the refrigerant of the corresponding indoor terminal device. In one embodiment, the fluid regulating module is a manifold. In other embodiments, the fluid regulating module may also be a circulating pump.

[0079] In one embodiment, referring to Figure 2, the control device 1 can also be connected to the environment detection module 5. The environment detection module 5 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.

[0080] In one embodiment, referring to Figure 2, the control device 1 can also be connected to a temperature sensor 6, which is provided on the surface of the indoor terminal device 31 or the wall on which the indoor terminal device 31 is installed, for detecting the surface temperature of the indoor terminal device 31 or the temperature of the wall on which the indoor terminal device 31 is installed.

[0081] In one embodiment, referring to Figure 2, the control device 1 can also be connected to a temperature detection module 7, which is arranged on the water inlet side of the radiation terminal device to detect the temperature of the mixture of the refrigerant flowing out of the energy supply module and the refrigerant flowing out of the liquid supply module 4.

[0082] In the embodiment of the present application, referring to FIG2 , a control device 1 for an environmental conditioning device includes a processor 1001 (e.g., a CPU), a memory 1002, a timer 1003, and the like. The various components of the control device 1 are connected via a communication bus. The memory 1002 can be a high-speed RAM memory or a non-volatile memory such as a disk drive. The memory 1002 can also be a storage device independent of the processor 1001.

[0083] Those skilled in the art will understand that the device structure shown in FIG2 does not constitute a limitation on the device, and may include more or fewer components than shown, or a combination of certain components, or a different arrangement of components.

[0084] As shown in Figure 2, memory 1002, a storage medium, may include a control program for an environmental conditioning device. In the apparatus shown in Figure 2, processor 1001 may be configured to invoke the control program for the environmental conditioning device stored in memory 1002 and execute the steps of the environmental conditioning device control method described in the following embodiments.

[0085] An embodiment of the present application also provides a control method for an environmental conditioning device, which is applied to the above-mentioned environmental conditioning device.

[0086] Referring to Figure 3, an embodiment of a control method for an environmental conditioning device of the present application is proposed. In one embodiment, the environmental conditioning device includes a heat pump system and a coolant circulation system, the coolant circulation system includes a medium circulation loop and a liquid supply module, the medium circulation loop includes an energy supply module and at least two types of indoor terminal devices, the liquid outlet of the energy supply module is connected to the indoor terminal device and the liquid supply module, the heat pump system is connected to the energy supply module for heat exchange, the at least two types of indoor terminal devices include a first type terminal and a second type terminal, the liquid inlet of the first type terminal is connected to the liquid supply module, and the control method of the environmental conditioning device includes:

[0087] Step S10: Acquire demand information of the indoor terminal device and the type of the indoor terminal device, wherein the demand information includes whether the indoor terminal device has a heat exchange demand and the required refrigerant temperature of the indoor terminal device;

[0088] In one embodiment, demand information of each indoor terminal device in the environmental conditioning device is obtained.

[0089] The demand information may be determined based on instructions input by the user, or by monitoring the environmental status and / or human body status in the indoor terminal device.

[0090] The heat exchange demand here includes cooling demand or heating demand.

[0091] The types of indoor terminal devices include first-type terminals or second-type terminals. In one embodiment, the first-type terminal is a radiation terminal device, and the second-type terminal is a convection terminal device.

[0092] The required coolant temperature is specifically the target temperature that the coolant in an indoor terminal device must reach to meet the heat exchange and reliability requirements of the corresponding indoor terminal device. In one embodiment, the required coolant temperature is the target temperature of the coolant flowing into the corresponding indoor terminal device. The required coolant temperature of the target terminal device can be determined based on a user-set temperature or based on data monitored by a monitoring module in the space where the radiation terminal device is located.

[0093] Step S20: When the indoor terminal device includes a target terminal device, and the target terminal device includes a first target terminal of the first type of terminal and a second target terminal of the second type of terminal, determining the first target coolant temperature of the energy supply module according to the required coolant temperature of the second target terminal; wherein the target terminal device is the indoor terminal device with a heat exchange demand;

[0094] In one embodiment, the first target brine temperature is a target value of the outlet temperature of the energy supply module. In other embodiments, the first target brine temperature may also be a target value of the return temperature of the energy supply module, and so on.

[0095] In one embodiment, when the required refrigerant temperature of the second target terminal is one, the required refrigerant temperature of the second target terminal is determined to be the first target refrigerant temperature. When there are more than one required refrigerant temperature of the second target terminal, the first target refrigerant temperature here can be determined based on the required refrigerant temperatures of more than one second target terminal. Specifically, the maximum temperature, minimum temperature, or average temperature of the required refrigerant temperatures of more than one second target terminal can be determined as the first target refrigerant temperature. For example, the first target refrigerant temperature can be determined based on the required refrigerant temperature of a preset type of target terminal device. Alternatively, in cooling mode, the maximum value of the required refrigerant temperatures of all target terminal devices is used as the first target refrigerant temperature; in heating mode, the minimum value of the required refrigerant temperatures of all target terminal devices is used as the first target refrigerant temperature.

[0096] Step S30, adjusting the liquid supply module according to the required coolant temperature of the first target terminal and / or the first target coolant temperature;

[0097] Here, the opening of the liquid supply module can be adjusted according to the required refrigerant temperature of the first target end and / or the first target refrigerant temperature, or the liquid supply module can be controlled to be opened or closed according to the required refrigerant temperature of the first target end and / or the first target refrigerant temperature.

[0098] In one implementation, a target outlet liquid temperature of the liquid supply module may be determined based on the required brine temperature at the first target terminal and / or the first target brine temperature, and the operation of the liquid supply module may be controlled based on the target outlet liquid temperature. For example, the required brine temperature at the first target terminal may be determined as the target outlet liquid temperature, or a target correspondence between the required brine temperature at the first target terminal and the target outlet liquid temperature may be obtained based on the first target brine temperature, with different first target brine temperatures corresponding to different target correspondences. The target outlet liquid temperature corresponding to the required brine temperature at the first target terminal is determined based on the target correspondence.

[0099] In another implementation, the target opening degree of the liquid supply module can be determined based on the relationship between the required brine temperature at the first target terminal and the first target brine temperature, and the liquid supply module can be controlled to operate at the target opening degree. For example, the temperature difference between the first target brine temperature and the required brine temperature can be determined, and the target opening degree of the liquid supply module can be determined based on the temperature difference, etc.

[0100] When the liquid supply module is turned on, the temperature of the brine output by the liquid supply module is different from the temperature of the brine flowing out of the energy supply module. The temperature of the brine output by the liquid supply module may be higher or lower than the temperature of the brine flowing out of the energy supply module. When the liquid supply module is turned on, the brine can be input to the first target terminal to which it is connected. Based on this, the brine flowing out of the energy supply module and the brine flowing out of the liquid supply module can both flow into the first target terminal. The temperature of the brine flowing into the first target terminal may be higher or lower than the temperature of the brine flowing out of the energy supply module.

[0101] Step S40: Controlling the operation of the heat pump system according to the first target coolant temperature.

[0102] In cooling mode, the heat pump system can be controlled to operate in a cooling manner according to the first target refrigerant temperature to release cold energy to the energy supply module; in heating mode, the heat pump system can be controlled to operate in a heating manner according to the first target refrigerant temperature to release heat to the energy supply module.

[0103] In one embodiment, the actual refrigerant temperature currently flowing out of the energy supply module is detected, and the operation of the heat pump system is controlled based on the temperature difference between the actual refrigerant temperature and a first target refrigerant temperature, so that the refrigerant temperature flowing out of the energy supply module reaches the first target refrigerant temperature. Specifically, the operation of at least one of the following components, such as a compressor, a throttling component, and a fan corresponding to a heat exchanger, in the heat pump system can be controlled based on the temperature difference. For example, when the energy supply module is in a cooling state, if the temperature difference is less than a first preset temperature difference, the compressor in the heat pump system is controlled to operate at a lower frequency; if the temperature difference is greater than a second preset temperature difference, the compressor in the heat pump system is controlled to operate at a higher frequency, wherein the first preset temperature difference is less than the second preset temperature difference.

[0104] The order in which steps S30 and S40 are executed is not specifically limited. During the execution of steps S30 and S40, the coolant circulation system is controlled to operate so that the coolant absorbs the energy of the energy supply module and then flows to each target terminal device. Specifically, the circulation pump in the coolant circulation system is controlled to be turned on, and the control valve corresponding to the target terminal device is controlled to be turned on. When the circulation pump is turned on, the coolant can be driven to circulate in the medium circulation loop. When the coolant flows through the energy supply module, it can absorb the energy of the energy supply module. When the corresponding control valve is opened, it flows to the corresponding target terminal device to release energy.

[0105] A control method for an environmental conditioning device is proposed in an embodiment of the present application. When the method determines through demand information that there are different types of target terminal devices with heat exchange requirements, the method determines the first target refrigerant temperature according to the required refrigerant temperature of the second type of terminal with heat exchange requirements to control the operation of the heat pump system, and adjusts the liquid supply module according to the required refrigerant temperature and / or the first target refrigerant temperature of the first type of terminal with heat exchange requirements. Based on this, it can be ensured that the refrigerant flowing into the second type of terminal from the power supply module can meet its usage requirements, and the refrigerant flowing into the first type of terminal from the power supply module can also meet its usage requirements under the regulation of the liquid supply module, so that the refrigerant temperature flowing into different types of target terminal devices can be differentiated according to their actual needs, thereby improving the effect of taking into account the needs of each device when the environmental conditioning device uses different types of terminal devices at the same time.

[0106] Furthermore, based on the above embodiment, another embodiment of the control method of the environmental conditioning device of the present application is proposed. In one embodiment, the liquid outlet of the energy supply module is connected to the first type terminal, the liquid supply module, and the second type terminal. The liquid supply module is located upstream of the first type terminal and is used to adjust the temperature of the coolant flowing into the first type terminal. The liquid outlet of the first type terminal and / or the liquid outlet of the second type terminal are connected to the liquid supply module. The step of adjusting the liquid supply module according to the required coolant temperature of the first target terminal and / or the first target coolant temperature includes:

[0107] The opening degree of the liquid supply module is adjusted according to the required coolant temperature of the first target terminal and / or the first target coolant temperature.

[0108] In one embodiment, the liquid supply module is a water mixing proportional valve, and the opening of the water mixing proportional valve is adjusted according to the required brine temperature of the first target terminal and / or the first target brine temperature.

[0109] When the liquid supply module is turned on, the coolant flowing out of the first target terminal and / or the coolant flowing out of the second target terminal mixes with the coolant flowing out of the energy supply module and then flows into the radiation terminal device.

[0110] When the environmental conditioning equipment operates in cooling mode, the energy supply module is in a cooling state, and the liquid inlet of the second target terminal is not connected to the liquid outlet of the liquid supply module, then the temperature of the refrigerant flowing into the second target terminal is the same as the temperature of the refrigerant flowing out of the energy supply module; the temperature of the refrigerant flowing out of the first target terminal and / or the second target terminal after heat exchange will be higher than the temperature of the refrigerant flowing out of the energy supply module, and the refrigerant with relatively high temperature is mixed with the refrigerant flowing out of the energy supply module and flows into the first target terminal. The temperature of the refrigerant flowing into the first target terminal will be higher than the temperature of the refrigerant flowing out of the energy supply module, that is, the temperature of the refrigerant flowing into the first target terminal is higher than the temperature of the refrigerant flowing out of the energy supply module, that is, the temperature of the refrigerant flowing into the first target terminal is higher than the temperature of the refrigerant flowing into the second target terminal.

[0111] When the environmental conditioning device operates in heating mode, the energy supply module is in a heating state, and the liquid inlet of the second target terminal is not connected to the liquid outlet of the liquid supply module, then the temperature of the refrigerant flowing into the second target terminal is the same as the refrigerant temperature of the energy supply module; the temperature of the refrigerant flowing out of the first target terminal and / or the second target terminal after heat exchange will be lower than the temperature of the refrigerant flowing out of the energy supply module, and the refrigerant with relatively low temperature is mixed with the refrigerant flowing out of the energy supply module and flows into the radiation terminal device. The temperature of the refrigerant flowing into the first target terminal will be lower than the temperature of the refrigerant flowing out of the energy supply module, that is, the temperature of the refrigerant flowing into the first target terminal is lower than the temperature of the refrigerant flowing out of the energy supply module, that is, the temperature of the refrigerant flowing into the first target terminal is lower than the temperature of the refrigerant flowing into the second target terminal.

[0112] Adjusting the opening of the liquid supply module here includes one of the following methods: increasing the opening, decreasing the opening, maintaining the current opening, operating at the target opening, and so on.

[0113] In one implementation, the target outlet temperature of the liquid supply module is determined according to the required refrigerant temperature at the first target terminal, and the opening of the liquid supply module is adjusted according to the target outlet temperature.

[0114] In another implementation, the opening adjustment value is determined according to the temperature difference between the required refrigerant temperature at the first target terminal and the first target refrigerant temperature, and the liquid supply module is controlled to adjust the opening according to the opening adjustment value.

[0115] In yet another implementation, the target outlet temperature of the liquid supply module is determined according to the first target coolant temperature, and the opening degree of the liquid supply module is adjusted according to the target outlet temperature.

[0116] In one embodiment, the above-described method improves the precision of the opening control of the liquid supply module, ensuring that the temperature of the refrigerant flowing into the first target terminal accurately meets the requirements of the first target module. Specifically, when the environmental conditioning device is operating in cooling mode, the cooling effect of the second target terminal is maintained while preventing condensation at the first target terminal or the space where the first target terminal is located. When the environmental conditioning device is operating in heating mode, the heating effect of the second target terminal is maintained while preventing the first target terminal from overheating and cracking. This allows for achieving heat exchange efficiency at each target terminal while improving the operational reliability of the first target terminal.

[0117] In one embodiment, the control method of the environmental conditioning equipment also includes: obtaining the mixed liquid temperature flowing out of the liquid supply module and / or the return liquid temperature flowing into the liquid supply module from the first target terminal; adjusting the opening of the liquid supply module according to the required refrigerant temperature of the first target terminal and / or the first target refrigerant temperature, and also includes: adjusting the opening of the liquid supply module according to the required refrigerant temperature of the first target terminal and / or the first target refrigerant temperature, as well as the mixed liquid temperature and / or the return liquid temperature.

[0118] The mixed liquid temperature can be detected by the temperature detection module. The return liquid temperature can be detected by the temperature detection module between the liquid inlet of the liquid supply module and the liquid outlet of the first target end.

[0119] In one embodiment, a relationship parameter between the mixed liquid temperature and the required coolant temperature of the first target terminal is determined; and the opening of the liquid supply module is adjusted based on the relationship parameter. The relationship parameter includes a magnitude relationship, a temperature difference, or a ratio between the mixed liquid temperature and the required coolant temperature of the first target terminal. An opening adjustment parameter or a target opening of the liquid supply module is determined based on the quantitative or magnitude relationship between the mixed liquid temperature and the required coolant temperature of the first target terminal. The liquid supply module is controlled to adjust its current opening according to the opening adjustment parameter, or the liquid supply module is controlled to operate from the current opening to the target opening.

[0120] In one embodiment, when the environmental conditioning device is in cooling mode, the mixed liquid temperature is greater than the required refrigerant temperature of the first target terminal, and the liquid supply module is controlled to reduce the opening to reduce the amount of liquid entering the liquid supply module; when the mixed liquid temperature is less than the required refrigerant temperature of the first target terminal, the liquid supply module is controlled to increase the opening to increase the amount of liquid entering the liquid supply module. When the environmental conditioning device is in heating mode, the mixed liquid temperature is greater than the required refrigerant temperature of the first target terminal, the liquid supply module is controlled to increase the opening to increase the amount of liquid entering the liquid supply module; when the mixed liquid temperature is less than the required refrigerant temperature of the first target terminal, the liquid supply module is controlled to reduce the opening to reduce the amount of liquid entering the liquid supply module. The amount of liquid entering here specifically refers to the amount of refrigerant flowing into the liquid supply module from the first target terminal and / or the second target terminal. The opening adjustment value in the process of increasing or decreasing the opening can be a pre-set fixed value, or it can be a value determined according to the actual operating conditions of the environmental conditioning device.

[0121] Furthermore, the opening adjustment direction can be determined based on the relationship parameters between the mixed liquid temperature and the first required refrigerant temperature, the opening adjustment value can be determined based on the return liquid temperature and the first target refrigerant temperature, and the liquid supply module can be controlled to adjust the opening based on the opening adjustment direction and the opening adjustment value.

[0122] In one embodiment, the above method is conducive to improving the accuracy of the opening control of the liquid supply module, thereby further ensuring that the temperature of the refrigerant flowing into the first target end can accurately meet its actual needs such as heat exchange requirements and reliability requirements.

[0123] In other embodiments, the opening of the liquid supply module can also be adjusted according to the return liquid temperature and the first target refrigerant temperature, or the opening of the liquid supply module here can be adjusted according to the temperature difference between the mixed liquid temperature, the return liquid temperature, the first target refrigerant temperature and the required refrigerant temperature at the first target end.

[0124] In one embodiment, after the step of obtaining the demand information of the indoor terminal device, the method further includes: when the target terminal device exists and all the target terminal devices are of the same type, controlling the liquid supply module to be closed.

[0125] When the liquid supply module is closed, the connecting pipe between the liquid outlet of the energy supply module and the liquid inlet of the radiation terminal device is blocked from the liquid outlet of the liquid supply module, and the liquid inlet temperature of each target terminal device is the same as the liquid outlet temperature of the energy supply module.

[0126] In one embodiment, the above-mentioned method is helpful to ensure that when target terminal devices of the same type are used at the same time, the heat exchange effect of each target terminal device can be effectively improved.

[0127] Furthermore, 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 one embodiment, referring to FIG. 4 , after step S40, the method further includes:

[0128] Step S50, when a preset condition is met, determining a second target brine temperature of the energy supply module according to the required brine temperature of the first target terminal, wherein the preset condition indicates that the first target terminal has a reliability risk;

[0129] The reliability risk here includes cracking risk, condensation risk, or unknown risk, etc. The preset condition includes the target temperature range that the mixed liquid temperature needs to reach or the target relationship that needs to be achieved between the mixed liquid temperature and the target temperature when the first target terminal has a reliability risk.

[0130] In one embodiment, the required brine temperature of the first target terminal is determined as the second target brine temperature.

[0131] Step S60: Controlling the operation of the heat pump system according to the second target coolant temperature.

[0132] In cooling mode, the heat pump system can be controlled to operate in cooling mode according to the second target refrigerant temperature to release cold energy to the energy supply module; in heating mode, the heat pump system can be controlled to operate in heating mode according to the second target refrigerant temperature to release heat to the energy supply module.

[0133] The outlet temperature of the energy supply module is obtained, and the operation of the heat pump system is controlled based on the outlet temperature and the second target coolant temperature. Specifically, the operating frequency of the compressor in the heat pump system, and / or the opening of the throttling device, and / or the fan speed corresponding to the first heat exchanger can be controlled based on the outlet temperature and the second target coolant temperature.

[0134] After step S40 , when the environmental conditioning device does not meet the preset condition, the heat pump system may be controlled to operate at the first target coolant temperature.

[0135] In one embodiment, the above-mentioned method is beneficial for timely setting the target refrigerant temperature of the energy supply module based on the required refrigerant temperature of the first target terminal when there is a reliability risk at the first target terminal and the risk cannot be reduced by the temperature regulation function of the liquid supply module, which is beneficial for effectively reducing the reliability risk problem of the first target terminal.

[0136] In one embodiment, when the heat pump system operates in cooling mode, the preset conditions include the temperature difference between the current mixed liquid temperature flowing out of the liquid supply module and the target mixed liquid temperature being less than or equal to a first preset temperature difference, or the temperature difference between the mixed liquid temperature and the target mixed liquid temperature being less than or equal to the first preset temperature difference and persisting for a first duration, or the mixed liquid temperature detection failing. A temperature difference less than or equal to the first preset temperature difference indicates that the refrigerant temperature flowing into the radiation terminal device is too low.

[0137] In one embodiment, when the heat pump system operates in heating mode, the preset conditions include the temperature difference between the current mixed liquid temperature flowing out of the liquid supply module and the target mixed liquid temperature being greater than or equal to a second preset temperature difference, or the temperature difference between the mixed liquid temperature and the target mixed liquid temperature being greater than or equal to the second preset temperature difference and persisting for a second duration, or the mixed liquid temperature detection failing. A temperature difference greater than or equal to the second preset temperature difference indicates that the refrigerant temperature flowing into the radiation terminal device is too high.

[0138] It should be noted that the temperature difference value here is specifically the calculation result obtained by subtracting the target mixed liquid temperature from the mixed liquid temperature. The failure of mixed liquid temperature detection here may be caused by damage to the temperature detection module used to detect the mixed liquid temperature or a communication failure between the temperature detection module and the control device, etc. The target mixed liquid temperature can be a pre-set fixed value or determined based on the actual operating conditions of the radiation terminal device. The first preset temperature difference and / or the second preset temperature difference can be a pre-set fixed temperature difference or determined based on the liquid outlet temperature of the radiation terminal device.

[0139] In one embodiment, setting the preset conditions in the above manner is conducive to improving the accurate identification of reliability risks of radiation terminal equipment.

[0140] In one embodiment, the step of obtaining the required refrigerant temperature of the target terminal device includes: determining the corresponding required refrigerant temperature based on the indoor temperature of the indoor space where the target terminal device is located and the corresponding indoor target temperature; and / or determining the corresponding required refrigerant temperature based on the dew point temperature of the indoor space where the target terminal device is located and the corresponding indoor terminal device temperature.

[0141] The indoor terminal device temperature may include the refrigerant temperature of the target terminal device, the surface temperature of the target terminal device, or the wall temperature of the wall on which the target terminal device is installed, and the like.

[0142] In the process of determining the corresponding required refrigerant temperature according to the indoor temperature of the indoor space where the target terminal device is located and the corresponding indoor target temperature, and determining the corresponding required refrigerant temperature according to the dew point temperature of the indoor space where the target terminal device is located and the corresponding indoor terminal device temperature, a first reference refrigerant temperature can be determined according to the indoor temperature of the indoor space where the target terminal device is located and the corresponding indoor target temperature, a second reference refrigerant temperature can be determined according to the dew point temperature of the indoor space where the target terminal device is located and the corresponding indoor terminal device temperature, and the corresponding required refrigerant temperature can be determined according to the first reference refrigerant temperature and the second reference refrigerant temperature. Alternatively, the corresponding required refrigerant temperature can be determined by combining the indoor temperature of the indoor space where the target terminal device is located and the corresponding indoor target temperature, and the dew point temperature of the indoor space where the target terminal device is located and the corresponding indoor terminal device temperature to obtain the corresponding required refrigerant temperature.

[0143] In one embodiment, the required refrigerant temperature is determined based on the indoor temperature and the indoor target temperature, which is conducive to ensuring that the determined required refrigerant temperature can accurately reflect the actual heat exchange demand of the corresponding target terminal device. The required refrigerant temperature is determined based on the dew point temperature and the corresponding indoor terminal device temperature, which is conducive to reducing the condensation risk of the corresponding target terminal device. The required refrigerant temperature is determined in combination with the indoor temperature, indoor target temperature, dew point temperature and indoor terminal device temperature, which is conducive to ensuring that the heat exchange demand of the target terminal device is met while reducing the condensation risk.

[0144] In one embodiment, the step of obtaining the required coolant temperature of the target terminal device includes:

[0145] When the target terminal device is the first target terminal device with cooling demand, the corresponding required refrigerant temperature is determined according to the indoor temperature of the indoor space where the target terminal device is located and the corresponding indoor target temperature, and according to the dew point temperature of the indoor space where the target terminal device is located and the corresponding indoor terminal device temperature;

[0146] When the target terminal device is the second target terminal with cooling demand, or when the target terminal device has heating demand, the corresponding required refrigerant temperature is determined according to the indoor temperature of the indoor space where the target terminal device is located and the corresponding indoor target temperature.

[0147] In one embodiment, there is a high possibility that condensation risk will occur when the temperature of the refrigerant flowing into the first target terminal such as the radiation terminal device during the cooling process is too low. Therefore, the required refrigerant temperature, indoor temperature, indoor target temperature, dew point temperature and indoor terminal device temperature corresponding to the first target terminal such as the radiation terminal device that needs to be cooled are determined, which is beneficial to satisfying the heat exchange effect of the first target terminal such as the radiation terminal device while reducing the condensation risk; and the second target terminal such as the convection terminal device has a lower condensation risk during the cooling process or any type of terminal device during the heating process. Therefore, the required refrigerant temperature is determined solely by the indoor temperature and the indoor target temperature, which is beneficial to avoid the restriction of anti-condensation on the required refrigerant temperature and to improve the heat exchange effect of the terminal device.

[0148] In one embodiment, the step of determining the corresponding required refrigerant temperature based on the indoor temperature of the indoor space where the target terminal device is located and the corresponding indoor target temperature includes: when the target terminal device has a cooling demand and the temperature difference between the indoor temperature and the indoor target temperature is greater than a first preset value, lowering the refrigerant temperature currently required by the target terminal device to obtain the corresponding required refrigerant temperature; when the target terminal device has a cooling demand and the temperature difference between the indoor temperature and the indoor target temperature is less than or equal to the first preset value, increasing the refrigerant temperature currently required by the target terminal device to obtain the corresponding required refrigerant temperature.

[0149] The first preset value may be a pre-set fixed value, or may be determined according to user-set parameters. In one embodiment, the first preset value is greater than 0.

[0150] If the temperature difference between the indoor temperature and the indoor target temperature is greater than the first preset value, it indicates that the temperature of the corresponding indoor space is too high and deviates from the user's comfort; if the temperature difference between the indoor temperature and the indoor target temperature is less than or equal to the first preset value, it indicates that the temperature of the corresponding indoor space is close to the user's comfort state.

[0151] The refrigerant temperature currently required by the target terminal device may be a preset fixed value, or may be a value determined before the current moment based on the actual working conditions of the corresponding space before the current moment.

[0152] When lowering or increasing the refrigerant temperature currently required by the target terminal device, it can be adjusted according to a pre-set fixed temperature adjustment value, or it can be adjusted according to a temperature adjustment value determined based on the temperature difference between the indoor temperature and the indoor target temperature.

[0153] In one embodiment, through the above method, the required refrigerant temperature of the target terminal device can be dynamically adjusted according to the actual situation of the indoor space to ensure the accuracy of the cooling capacity output by the heat pump system when the heat pump system is controlled according to the target refrigerant temperature determined corresponding to the required refrigerant temperature, thereby ensuring the reliable operation of each target terminal device while improving the cooling effect of each target terminal device.

[0154] In one embodiment, the step of determining the corresponding required refrigerant temperature based on the indoor temperature of the indoor space with heat exchange demand and the corresponding indoor target temperature includes: when the target terminal device has a heating demand and the temperature difference between the indoor target temperature and the indoor temperature is greater than a second preset value, increasing the refrigerant temperature currently required by the target terminal device to obtain the corresponding required refrigerant temperature; when the target terminal device has a heating demand and the temperature difference between the indoor target temperature and the indoor temperature is less than or equal to the second preset value, reducing the refrigerant temperature currently required by the target terminal device to obtain the corresponding required refrigerant temperature.

[0155] The second preset value may be a pre-set fixed value, or may be determined according to user-set parameters. In one embodiment, the second preset value is greater than 0.

[0156] If the temperature difference between the indoor target temperature and the indoor temperature is greater than the second preset value, it indicates that the temperature of the corresponding indoor space is too low and deviates from the user comfort; if the temperature difference between the indoor target temperature and the indoor temperature is less than or equal to the second preset value, it indicates that the temperature of the corresponding indoor space is close to the user comfort state.

[0157] The refrigerant temperature currently required by the target terminal device may be a preset fixed value, or may be a value determined before the current moment based on the actual working conditions of the corresponding space before the current moment.

[0158] When lowering or increasing the refrigerant temperature currently required by the target terminal device, it can be adjusted according to a pre-set fixed temperature adjustment value, or it can be adjusted according to the temperature difference between the indoor target temperature and the indoor temperature.

[0159] In one embodiment, through the above method, the required refrigerant temperature of the target terminal device can be dynamically adjusted according to the actual situation of the indoor space to ensure the accuracy of the heat output of the heat pump system when the heat pump system is controlled according to the target refrigerant temperature determined corresponding to the required refrigerant temperature, thereby ensuring the reliable operation of each target terminal device while improving the heating effect of each target terminal device.

[0160] In one embodiment, the step of determining the corresponding required refrigerant temperature based on the dew point temperature of the indoor space where the target terminal device is located and the corresponding indoor terminal device temperature includes: when the target terminal device has a cooling demand and the temperature difference between the indoor terminal device temperature and the dew point temperature is greater than or equal to a third preset value, lowering the refrigerant temperature currently required by the target terminal device to obtain the corresponding required refrigerant temperature, or using the current refrigerant temperature of the target terminal device as the corresponding required refrigerant temperature. When the target terminal device has a cooling demand and the temperature difference between the indoor terminal device temperature and the dew point temperature is less than the third preset value, increasing the refrigerant temperature currently required by the target terminal device to obtain the corresponding required refrigerant temperature.

[0161] The third preset value may be a pre-set fixed value, or may be determined according to user-set parameters. In one embodiment, the third preset value is less than or equal to 0.

[0162] The refrigerant temperature currently required by the target terminal device may be a pre-set fixed value, or may be a value determined before the current moment based on the actual working conditions of the corresponding space before the current moment. In one implementation, when determining the required refrigerant temperature of the corresponding target terminal device in combination with the indoor temperature, the indoor target temperature, the indoor terminal device temperature, and the dew point temperature, the required refrigerant temperature corresponding to the target terminal device determined by the above-mentioned indoor temperature and the indoor target temperature may be used as the refrigerant temperature currently required by the target terminal device here. Alternatively, the required refrigerant temperature determined here by the indoor terminal device temperature and the dew point temperature may be used as the refrigerant temperature currently required by the target terminal device in the process of determining the required refrigerant temperature in combination with the indoor temperature and the indoor target temperature.

[0163] When lowering or increasing the refrigerant temperature currently required by the target terminal device, it can be adjusted according to a pre-set fixed temperature adjustment value, or it can be adjusted according to the temperature difference between the indoor target temperature and the indoor temperature.

[0164] In one embodiment, through the above method, the required refrigerant temperature of the target terminal device can be dynamically adjusted to adapt to the condensation risk of indoor space and / or indoor terminal devices such as radiation terminal devices, so as to ensure the accuracy of the cooling capacity output by the heat pump system when the heat pump system is controlled according to the target refrigerant temperature determined corresponding to the required refrigerant temperature, thereby ensuring the cooling effect of the target terminal device while reducing the condensation risk.

[0165] In one embodiment, after the step of determining the required brine temperature corresponding to the target terminal device, the method further includes:

[0166] When the target terminal device has a cooling demand and the corresponding required coolant temperature is less than the minimum temperature, updating the required coolant temperature corresponding to the target terminal device to the minimum temperature; and / or,

[0167] When the target terminal device has a heating demand and the corresponding required coolant temperature is greater than the maximum temperature, updating the required coolant temperature corresponding to the target terminal device to the maximum temperature;

[0168] Among them, the minimum temperature when the target terminal device is a convection heat exchange device is lower than the minimum temperature when the target terminal device is a radiation terminal device, and the maximum temperature when the target terminal device is a convection heat exchange device is higher than the maximum temperature when the target terminal device is a radiation terminal device.

[0169] Based on this, when the convection heat exchange device and the radiation terminal device are operated at the same time, the heat exchange effect of the convection terminal device is effectively improved and the operation reliability of the radiation terminal device is effectively improved.
