[0050] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0051] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0052] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0053] The main solution of this application embodiment is: to propose an environmental control system, which includes a temperature control system and a refrigerant circulation system. The refrigerant circulation system includes a first heat exchange module, a second heat exchange module, and an indoor terminal device. The temperature control system is heat-exchange connected to the first heat exchange module. The second heat exchange module is configured to exchange heat with a centralized heating system. The pipeline connected to the liquid outlet of the first heat exchange module is defined as the liquid outlet pipeline. The second heat exchange module is located in the liquid outlet pipeline.

[0054] In this embodiment, for ease of description, the environmental control system will be used as the implementing entity for the following description.

[0055] In existing technologies, user-installed indoor temperature control systems and centralized heating systems are generally two independent systems. Incoordination between the two systems not only affects indoor temperature comfort but also easily wastes energy.

[0056] This application provides the above-mentioned solution, in which the refrigerant circulation system in the temperature control system exchanges heat with the temperature control system and the central heating system through different heat exchange modules. After the refrigerant is heated by the temperature control system, it can be further heated by the central heating system to provide heat to the indoor terminal device. The temperature control system and the central heating system can act as dual heat sources to regulate the temperature of the refrigerant flowing into the indoor terminal device. Based on this, the two systems no longer independently regulate the temperature of the indoor environment. The temperature control system can adjust the heat exchange to adapt to the heating situation of the central heating system, ensuring that the two systems can coordinate and cooperate to match the heat exchange of the indoor terminal device with the actual comfort needs of the user. This effectively reduces unnecessary heat exchange output from the temperature control system, thus improving indoor comfort and saving energy.

[0057] This application provides an environmental control system 200.

[0058] Reference Figure 1 , refer to Figures 1 to 2 The arrows indicate the flow direction of the refrigerant. The environmental control system 200 includes a temperature control system 21 and a refrigerant circulation system. The refrigerant circulation system includes a first heat exchange module 221, a second heat exchange module 222, and an indoor terminal device 223. The temperature control system 21 is connected to the first heat exchange module 221 for heat exchange, and the second heat exchange module 222 is configured to exchange heat with the central heating system 300.

[0059] The temperature control system 21 can be a system with heating function. The temperature control system 21 can heat the first heat exchange module 221 to increase the temperature of the refrigerant flowing through the first heat exchange module 221. The temperature control system 21 can also be a system that switches between cooling and heating functions. When cooling, the temperature control system 21 can cool the first heat exchange module 221 to lower the temperature of the refrigerant flowing through it; when heating, the temperature control system 21 can heat the first heat exchange module 221 to increase the temperature of the refrigerant flowing through it. In this embodiment, the temperature control system 21 includes a gas system (e.g., a gas-fired wall-hung boiler) or a heat pump system. The gas system may include a burner, a gas proportional valve, and a gas fan. The gas fan, when turned on, drives air from its location into the area where the burner is located to achieve combustion conditions. The gas proportional valve can be used to adjust the amount of gas supplied to the burner, and the burner can burn the gas to heat the first heat exchange module 221. The heat pump system may include a second heat exchanger, which is heat exchanged with the first heat exchange module 221.

[0060] Indoor terminal unit 223 may include radiant terminal unit or convection terminal unit. Convection terminal unit may include a heat exchanger and a corresponding convection fan, which drives the air in its space to exchange heat with the heat exchanger; for example, convection terminal unit includes fan coil units. Radiant terminal unit may include radiant panels, underfloor heating, radiators, etc. The refrigerant circulation system may include one or more indoor terminal units 223. When there are more than one indoor terminal unit 223, they may be located in the same indoor space or distributed in different indoor spaces. When there are more than one indoor terminal unit 223, the types of the more than one indoor terminal unit 223 may be the same or different; for example, the more than one indoor terminal unit 223 may include radiant terminal unit and convection terminal unit; or, all of the more than one indoor terminal unit 223 may be radiant terminal unit; or, all of the more than one indoor terminal unit 223 may be convection terminal unit.

[0061] The first heat exchange module 221 refers to the pipe section in the refrigerant circulation system that exchanges heat with the temperature control system 21. When the temperature control system 21 is a gas system, the gas system can heat the first heat exchange module 221 using the energy generated from burning the gas. When the temperature control system 21 is a heat pump system, the heat exchanger in the heat pump system can be connected to the first heat exchange module 221 in a plate heat exchanger for heat exchange.

[0062] The second heat exchange module 222 refers to the pipe section in the refrigerant circulation system that exchanges heat with the central heating system 300. When the central heating system 300 is equipped with a heat exchanger, the second heat exchange module 222 is connected to the heat exchanger of the central heating system 300 for heat exchange. When the central heating system 300 is not equipped with a heat exchanger, but is equipped with a liquid supply pipe and a liquid return pipe, the refrigerant circulation system may also include a heat exchange device. The second heat exchange module 222 is located in the heat exchange device. The heat exchange device may be equipped with an inlet connected to the liquid inlet pipe and an outlet connected to the liquid outlet pipe, thereby enabling the central heating system 300 and the refrigerant circulation system to exchange heat in this heat exchange device.

[0063] The refrigerant circulation system is filled with refrigerant, enabling energy storage and exchange. In this embodiment, the refrigerant is water. In other embodiments, the refrigerant may be other types of energy storage liquids, such as salt solutions. The refrigerant in the refrigerant circulation system can circulate. When the refrigerant flows through the indoor terminal device 223, it can release cold or heat to regulate the temperature of the indoor environment. When the refrigerant flows through the second heat exchange module 222 and the central heating system 300 is in heating mode, the refrigerant temperature can increase. When the refrigerant flows through the first heat exchange module 221 and the temperature control system 21 is in heating mode, the refrigerant temperature can increase. When the refrigerant flows through the first heat exchange module 221 and the temperature control system 21 is in cooling mode, the refrigerant temperature can decrease.

[0064] When the first heat exchange module 221, the second heat exchange module 222, and the indoor terminal device 223 are all located in the same circulation loop, they can be connected sequentially; or they can be connected sequentially. When the refrigerant circulation system includes different circulation loops and the different circulation loops are connected by heat exchange, the first heat exchange module 221, the second heat exchange module 222, and the indoor terminal device 223 can be located in different circulation loops; or, the first heat exchange module 221 and the second heat exchange module 222 are located in the first circulation loop, and the indoor terminal device 223 is located in the second circulation loop; or, the first heat exchange module 221 is located in the first circulation loop, and the second heat exchange module 222 and the indoor terminal device 223 are located in the second circulation loop; or, the first heat exchange module 221 and the indoor terminal device 223 are located in the first circulation loop, and the second heat exchange module 222 is located in the second circulation loop, and so on.

[0065] The centralized heating system 300 is a system that simultaneously heats the indoor environment regulated by the environmental control system 200 and multiple indoor environments other than the indoor environment regulated by the environmental control system 200. The centralized heating system 300 has at least the following characteristics: the cost of providing a unit of heat by the centralized heating system 300 is lower than the cost of providing a unit of heat by the temperature control system 21; the heating period of the centralized heating system 300 is fixed and will not change to adapt to the actual needs of the indoor environment regulated by the environmental control system 200; the supply liquid temperature of the centralized heating system 300 will fluctuate and is easily affected by environmental factors or usage needs. Users can adjust the supply liquid volume (e.g., adjust the opening of the flow valve corresponding to the indoor environment) but cannot adjust the supply liquid temperature. For example, the supply liquid temperature will be higher when the ambient temperature is high, lower when the ambient temperature is low, and lower when there are many indoor environments using the centralized heating system 300 to provide heat, etc.; the indoor space heated by the centralized heating system 300 will have cooling needs at certain times; the impurities in the refrigerant in the centralized heating system 300 are more than those in the refrigerant circulation system, meaning the water quality in the centralized heating system 300 is worse than the water quality in the refrigerant circulation system, etc.

[0066] The pipeline connected to the liquid outlet of the first heat exchange module 221 is defined as the liquid outlet pipeline, and the second heat exchange module 222 is located in the liquid outlet pipeline.

[0067] In one implementation, when the first heat exchange module 221, the second heat exchange module 222, and the indoor terminal device 223 are all located in the same circulation loop, the pipeline between the liquid inlet of the indoor terminal device 223 and the liquid outlet of the first heat exchange module 221 is the liquid outlet pipeline. The refrigerant flowing out of the first heat exchange module 221 can first absorb the heat provided by the central heating system 300 through the second heat exchange module 222 before flowing into the indoor terminal device 223 for heat exchange.

[0068] In another implementation, the refrigerant circulation system includes a first loop 201 and a second loop 202, which can be connected by a heat exchange device 228. The first heat exchange module 221 and the second heat exchange module 222 are both located in the first loop 201, and the indoor terminal device 223 is located in the second loop 202. The pipeline between the liquid inlet of the heat exchange device 228 in the first loop 201 and the liquid outlet of the first heat exchange module 221 is the liquid inlet pipeline. The refrigerant flowing out of the first heat exchange module 221 can first absorb the heat provided by the central heating system 300 through the second heat exchange module 222, and then flow into the heat exchange device 228 to exchange heat with the refrigerant in the second loop 202 to provide heat for the indoor terminal device 223.

[0069] In this embodiment, the operating parameters of the temperature control system 21 can be adjusted to adapt to the temperature status parameters of the refrigerant circulation system, thereby ensuring that the heat exchange of the indoor terminal device 223 can meet the indoor comfort requirements regardless of whether the central heating system 300 is in a heating or non-heating state.

[0070] This application proposes an environmental control system 200. In this system, the refrigerant circulation system in the temperature control system 21 exchanges heat with both the temperature control system 21 and the central heating system 300 through different heat exchange modules. After the refrigerant is heated by the temperature control system 21, it can be further heated by the central heating system 300 to provide heat to the indoor terminal device 223. The temperature control system 21 and the central heating system 300 can act as dual heat sources to regulate the temperature of the refrigerant flowing into the indoor terminal device 223. Based on this, the two systems no longer independently regulate the indoor temperature. The temperature control system 21 can adjust the heat exchange to adapt to the heating conditions of the central heating system 300, ensuring that the two systems can coordinate to match the heat exchange of the indoor terminal device 223 with the user's actual comfort needs. This effectively reduces unnecessary heat exchange output from the temperature control system 21, thus improving indoor comfort and saving energy.

[0071] In one feasible implementation, refer to Figures 1 to 4The second heat exchange module 222 is disposed in the heat exchange device, which also includes a third heat exchange module 229. The second heat exchange module 222 and the third heat exchange module 229 are heat exchanged. The refrigerant channel in the second heat exchange module 222 is isolated from the refrigerant channel in the third heat exchange module 229. The two ends of the third heat exchange module 229 are respectively connected to the liquid supply pipe and the liquid return pipe of the central heating system 300.

[0072] The heat exchange device can be a plate heat exchanger, etc.

[0073] In this embodiment, the refrigerant in the central heating system 300 and the refrigerant in the second heat exchange module 222 exchange heat in mutually isolated channels. The refrigerant in the central heating system 300 will not mix with the refrigerant in the refrigerant circulation system, which can effectively prevent the refrigerant in the central heating system 300 from contaminating the refrigerant in the refrigerant circulation system and affecting the heat exchange effect of the refrigerant circulation system. Based on this, the above settings help to ensure that the central heating system 300 and the temperature control system 21 can coordinate and adjust the refrigerant temperature while further improving the heat exchange efficiency of the system.

[0074] In other embodiments, the refrigerant in the central heating system 300 and the refrigerant in the refrigerant circulation system can also exchange heat by mixing.

[0075] In one feasible implementation, refer to Figure 3 and Figure 4 The refrigerant circulation system includes a first loop 201 and a second loop 202, which are connected by a heat exchange device 228. The indoor terminal device 223 is located in the second loop 202, and the first heat exchange module 221 and the second heat exchange module 222 are located in the first loop 201.

[0076] In this embodiment, the heat exchange device 228 is a mixing device, such as a buffer tank. In other embodiments, the heat exchange device 228 may also include a separated first channel and a second channel, the first channel being connected to the first circuit 201 and the second channel being connected to the second circuit 202, wherein the refrigerant entering the first channel in the first circuit 201 exchanges heat with the refrigerant entering the second channel in the second circuit 202.

[0077] In this embodiment, the second heat exchange module 222 is located between the liquid inlet of the heat exchange device 228 in the first circuit 201 and the liquid outlet of the first heat exchange module 221.

[0078] In this embodiment, the refrigerant circulation system is a secondary circulation system. The temperature control system 21 and the central heating system 300 work together to provide energy to the secondary circulation system, which helps to ensure indoor comfort and improve system energy efficiency.

[0079] In one feasible implementation, refer to Figure 1 and Figure 2 The refrigerant circulation system may further include a liquid storage device 226 (e.g., a buffer water tank). The liquid storage device 226 may be located in a return pipe connected to the return port of the first heat exchange module 21 or in an outlet pipe connected to the outlet of the first heat exchange module 21. The outlet pipe is a pipe connected to the outlet of the first heat exchange module 221.

[0080] In this embodiment, the liquid storage device 226 is designed to store energy in the system, save energy consumption, and improve the stability of the refrigerant temperature in the refrigerant circulation system.

[0081] Based on any of the above embodiments, in this embodiment, reference is made to... Figure 2 and Figure 4 The refrigerant circulation system further includes a control valve 227 connected to the liquid outlet of the first heat exchange module 221, and the control valve 227 is connected in parallel with the second heat exchange module 222.

[0082] In this embodiment, the control valve 227 is an electric two-way valve.

[0083] When control valve 227 is open, the flow resistance of the pipeline where control valve 227 is located is less than the flow resistance of the pipeline where the second heat exchange module 222 is located. Therefore, the refrigerant flowing out of the first heat exchange module 221 flows through control valve 227 to heat the indoor terminal device 223 and stops flowing through the second heat exchange module 222 for heat exchange. When control valve 227 is closed, all the refrigerant flowing out of the first heat exchange module 221 flows through the second heat exchange module 222 for heat exchange and then further heats the indoor terminal device 223.

[0084] In this embodiment, by setting the control valve 227, it is beneficial to adjust whether the refrigerant exchanges heat with the central heating system 300 according to the actual heating situation and the actual heat exchange demand of the room. This reduces the unnecessary flow of the refrigerant into the second heat exchange module 222, which would reduce the heat exchange efficiency of the refrigerant or even cause energy loss. This is beneficial to further ensure indoor temperature comfort and improve the heat exchange efficiency of the system.

[0085] Based on any of the above embodiments, in this embodiment, the liquid outlet temperature of the first heat exchange module 221 corresponding to the temperature control system 21 is lower than the liquid supply temperature of the central heating system 300.

[0086] The outlet temperature here is the temperature of the refrigerant that flows out after the temperature control system 21 is running and exchanging heat with the first heat exchange module 221.

[0087] In this embodiment, the temperature control system 21 includes a heat pump system. Specifically, the temperature control system 21 may include a heat pump system with a single heating function or a heat pump system with both heating and cooling functions.

[0088] In one feasible implementation, the heat pump system includes a compressor and a second heat exchanger, a throttling device, and a first heat exchanger connected in sequence. The first heat exchanger is connected to the return port of the compressor, the second heat exchanger is connected to the exhaust port of the compressor, and the second heat exchanger is connected to the first heat exchange module 221 for heat exchange.

[0089] The first heat exchanger may be equipped with a first fan, which can drive the air in the space where it is located to exchange heat with the first heat exchanger.

[0090] When the heat pump system is running, the refrigerant discharged from the compressor flows through the second heat exchanger, the throttling device and the first heat exchanger in sequence before returning to the compressor. The second heat exchanger is in a condensing state and the first heat exchanger is in an evaporating state. The refrigerant flowing through the first heat exchange module 221 can absorb the heat released by the second heat exchanger and then rise in temperature.

[0091] In this embodiment, the temperature control system 21 is a heat pump system with a separate heating function. Based on this, the heating capacity of the heat pump system can be adjusted to adapt to the heating situation of the central heating system 300, ensuring that the heating capacity of the indoor terminal device 223 is accurately matched with the indoor temperature demand, thereby effectively improving indoor comfort and system energy efficiency.

[0092] In another feasible implementation, the heat pump system includes a compressor, a reversing assembly, and a first heat exchanger, a throttling device, and a second heat exchanger connected in sequence. The first heat exchanger, the second heat exchanger, the exhaust port of the compressor, and the return port of the compressor are all connected to the reversing assembly, and the second heat exchanger is heat exchanged with the first heat exchange module 221.

[0093] The first heat exchanger may be equipped with a first fan, which can drive the air in the space where it is located to exchange heat with the first heat exchanger.

[0094] A reversing assembly (such as a four-way valve) can switch the refrigerant flow direction between the first heat exchanger and the second heat exchanger. The reversing assembly has a first operating state and a second operating state. When the reversing assembly is operating in the first operating state, the compressor's discharge port is connected to the first heat exchanger and the compressor's return port is connected to the second heat exchanger. The refrigerant discharged from the compressor flows sequentially through the first heat exchanger, the throttling device, and the second heat exchanger before returning to the compressor. The first heat exchanger is in a condensing state, and the second heat exchanger is in an evaporating state. When the reversing assembly is operating in the second operating state, the compressor's discharge port is connected to the second heat exchanger and the compressor's return port is connected to the first heat exchanger. The refrigerant discharged from the compressor flows sequentially through the second heat exchanger, the throttling device, and the first heat exchanger before returning to the compressor. The second heat exchanger is in a condensing state, and the first heat exchanger is in an evaporating state.

[0095] When the commutation assembly is running in the first operating state, the refrigerant flowing through the first heat exchange module 221 can absorb the cold energy released by the second heat exchanger and then cool down; when the commutation assembly is running in the second operating state, the refrigerant flowing through the first heat exchange module 221 can absorb the heat released by the second heat exchanger and then heat up.

[0096] In this embodiment, the temperature control system 21 is a heat pump system with both cooling and heating functions. Based on this, the energy supply of the heat pump system and the energy supply of the central heating system 300 can cooperate with each other to ensure that the heating capacity of the indoor terminal device 223 is precisely matched with the indoor temperature demand, thereby effectively improving indoor comfort and system energy efficiency.

[0097] In this embodiment, the temperature control system 21 is a system in which the outlet temperature after heating is lower than the supply temperature of the central heating system 300. This helps to ensure the effectiveness of the central heating system 300 in supplementing the refrigerant flowing out of the first heat exchange module 221, and further ensures that the two systems can work together to ensure indoor comfort and save energy.

[0098] In other embodiments, the temperature control system 21 may also include an electric heating device, etc.

[0099] In one feasible implementation, refer to Figures 1 to 4 The refrigerant circulation system also includes a circulation pump 225, which, when turned on, can drive the refrigerant to circulate between different devices.

[0100] In one implementation, when the first heat exchange module 221, the second heat exchange module 222, and the indoor terminal device 223 are all located in the same circulation loop, there is one circulation pump 225. When the circulation pump 225 is turned on, it can drive the refrigerant to circulate among the first heat exchange module 221, the second heat exchange module 222, and the indoor terminal device 223.

[0101] In another implementation, the refrigerant circulation system includes the first loop 201 and the second loop 202 mentioned above. A circulation pump 225 can be installed in the loop where the indoor terminal device 223 is located, or a circulation pump 225 can be installed in the first loop 201 and the second loop 202 respectively. When the circulation pump 225 is turned on, it can drive the refrigerant to circulate in the corresponding loop.

[0102] In this embodiment, the above method helps to improve the refrigerant circulation efficiency and ensure the heat exchange effect of the system.

[0103] Based on any of the above embodiments, in this embodiment, reference is made to... Figures 1 to 4 There may be more than one indoor terminal unit 223, and the refrigerant circulation system may also include a distribution unit 224 (e.g., a water manifold).

[0104] In this embodiment, the indoor terminal device 223 includes a radiant terminal device.

[0105] The distribution device 224 can be used to distribute the refrigerant provided by the first heat exchange module 221 or the heat exchange device to the indoor terminal devices 223 that need to exchange heat, and collect the refrigerant flowing out of all the indoor terminal devices 223 after heat exchange and return it to the first heat exchange module 221.

[0106] The distribution unit 224 includes at least two fluid valves, which are configured one-to-one with the indoor terminal unit 223.

[0107] In this embodiment, the heat exchange in different indoor terminal devices 223 can be effectively distributed through the distribution device 224, ensuring that the temperature regulation needs of the areas where different indoor terminal devices 223 are located are effectively met, thereby further improving indoor temperature comfort.

[0109] When the refrigerant circulation system also includes control valve 227, the first temperature sensor 01 is located on the water inlet side of control valve 227 and the second heat exchange module 222.

[0110] In this embodiment, by setting the first temperature sensor 01, the control valve 227 or the temperature regulation system 21 can be accurately regulated based on the temperature detected by the first temperature sensor 01, thereby further improving the accuracy of the temperature regulation system 21 and the central heating system 300 in cooperating to supply energy, so as to further improve indoor comfort and system energy efficiency.

In this embodiment, the second temperature sensor 02 is located in the liquid supply pipe of the central heating system 300.

[0112] In this embodiment, the heating status of the central heating system 300 can be reflected by the setting of the second temperature sensor 02. The control valve 227 or the temperature regulation system 21 can be accurately regulated based on the temperature detected by the second temperature sensor 02, which is conducive to further improving the accuracy of the coordination between the temperature regulation system 21 and the central heating system 300 in energy supply, so as to further improve indoor comfort and system energy efficiency.

[0119] The environmental control system provided in this application, employing the control method of the environmental control system in the following embodiments, can solve the technical problem of how to improve indoor comfort and save energy consumption. Compared with the prior art, the beneficial effects of the environmental control system provided in this application are the same as the beneficial effects of the control method of the environmental control system provided in the following embodiments, and other technical features of this environmental control system are the same as those disclosed in the method of the following embodiments, and will not be repeated here.

[0120] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or environmental control system capable of performing the above functions. The following description uses an environmental control system as an example to illustrate this embodiment and the subsequent embodiments.

[0121] Based on this, embodiments of this application provide a control method for an environmental control system, referring to... Figure 6 , Figure 6 This is a flowchart illustrating the first embodiment of the control method for the environmental control system of this application.

[0122] In this embodiment, the control method of the environmental control system includes steps S10 to S20:

[0123] Step S10: Obtain the temperature status parameters of the refrigerant circulation system;

[0124] Temperature status parameters may include at least one of the following: refrigerant temperature, temperature of indoor terminal devices (e.g., surface temperature, heat exchanger temperature, outlet air temperature, etc.), etc. The refrigerant temperature may include at least one of the following: return liquid temperature of the first heat exchange module, outlet liquid temperature of the first heat exchange module, inlet liquid temperature of the second heat exchange module, outlet liquid temperature of the second heat exchange module, inlet liquid temperature of the indoor terminal device, outlet liquid temperature of the indoor terminal device, supply liquid temperature of the heat exchange device, outlet liquid temperature of the liquid storage device, etc.

[0125] Step S20: Control the temperature control system to adjust the heat supply according to the temperature status parameters.

[0126] Adjusting the heating supply may include increasing the heating supply, decreasing the heating supply, maintaining the current heating supply, stopping the heating supply, or maintaining the heating supply.

[0127] When the temperature control system includes a gas system, the heating capacity can be adjusted in at least one of the following ways: adjusting the gas volume, adjusting the speed of the gas fan, adjusting the heating power, etc.

[0128] When the temperature control system includes a gas system, the heating capacity can be adjusted by at least one of the following methods: adjusting the compressor frequency, adjusting the fan speed, adjusting the opening of the throttling device, etc.

[0129] In one implementation, the relationship between the temperature state parameters and the corresponding target temperature is determined, and the temperature control system is controlled to adjust the heat supply based on this relationship.

[0130] In another implementation, the temperature status parameters include the temperature at more than one different location in the refrigerant circulation system, and the temperature control system is adjusted to adjust the heat supply based on the relationship between the more than one temperature.

[0131] This embodiment provides a control method for an environmental conditioning system. Based on the aforementioned environmental conditioning system, the temperature state of the refrigerant circulation system can be adjusted in conjunction with the temperature control system and the central heating system. Regardless of the energy supply of the central heating system, it can be effectively reflected in the temperature state parameters of the refrigerant circulation system. Based on this, the heat supply of the temperature control system can be adjusted according to the temperature state of the refrigerant circulation system, which helps to ensure that the heat supply of the temperature control system is not too large or too small, accurately meeting the indoor temperature requirements, achieving indoor temperature comfort while saving energy.

[0132] In one feasible implementation, step S10 may include: obtaining the temperature of the first refrigerant flowing into the first heat exchange module, wherein the temperature status parameter includes the first refrigerant temperature; step S20 may include: when the first refrigerant temperature is greater than the target supply temperature, controlling the temperature control system to reduce the heat supply or stop the heat supply; and / or, when the first refrigerant temperature is less than the target supply temperature, controlling the temperature control system to maintain the heat supply.

[0133] The target liquid supply temperature is a pre-set target temperature for the liquid entering the indoor terminal device. This can include the target temperature for the liquid exiting the first heat exchange module or the target temperature for the liquid exiting the heat exchange device in the second loop, etc. The target liquid supply temperature can be determined based on the target ambient temperature required to meet comfort requirements in the indoor space where the indoor terminal device is located.

[0134] In this embodiment, the temperature control system includes a heat pump system, and controlling the temperature control system to reduce or stop the heating supply includes controlling the heat pump system to shut down the compressor and the fan, where the fan may refer to the first fan mentioned above. In other embodiments, when the temperature control system includes an electric heating device, the electric heating device may be controlled to shut down.

[0135] During the process of reducing or stopping the heating supply of the temperature control system, the aforementioned circulating pump can be kept running.

[0136] If the initial refrigerant temperature is lower than the target supply liquid temperature, the temperature control system can be controlled to maintain heating. If the temperature control system includes a heat pump system, the heat pump system can be controlled to keep the compressor and fan running.

[0137] In this embodiment, by employing the above-described method, when the return liquid temperature of the first heat exchange module is high enough to meet the heating requirements of the indoor terminal device, the heating output of the temperature control system is reduced to make greater use of the heat from the central heating system. This avoids excessive heat supply from the indoor terminal device and reduces energy consumption and heating costs for the temperature control system. When the return liquid heat from the first heat exchange module is insufficient, the combined use of heat from both the central heating system and the temperature control system helps ensure sufficient heat to meet indoor comfort requirements. Therefore, the above method achieves both guaranteed indoor heating comfort and energy savings.

[0138] In other embodiments, when the first refrigerant temperature is greater than or equal to the target supply temperature, the control valve can be opened to stop using the heat from the central heating system to heat the refrigerant in the refrigerant circulation system. Alternatively, when the first refrigerant temperature is less than the target supply temperature, the heat supply of the temperature control system can be adjusted according to the temperature difference between the first refrigerant temperature and the target supply temperature.

[0139] Based on any of the above embodiments, in the second embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. In addition, the environmental control system also includes the control valve described above; please refer to... Figure 7 The method further includes:

[0140] Step S100: Obtain status information, which indicates the operating status of the central heating system;

[0141] Status information can be obtained by detecting parameters of the central heating system and / or refrigerant circulation system, or by obtaining configuration information input by the user, or by obtaining information from the central heating system through network connection.

[0142] The status information may include at least one of the following: current time and heating period, liquid supply temperature of the central heating system, liquid supply temperature of the central heating system, and the temperature of the second refrigerant on the inlet side of the control valve and the second heat exchange module, etc. Here, the liquid supply temperature is the temperature of the refrigerant in the central heating system before heat exchange with the second heat exchange module.

[0143] In this embodiment, the operating status of the heating system includes whether it is in heating mode. In other embodiments, the operating status may also include the heating capacity of the centralized heating system, etc.

[0144] Step S200: Control the operation of the control valve according to the status information.

[0145] Here, status information can be used to control the valve to open or close, or adjust the opening degree.

[0146] In this embodiment, the control valve is opened or closed based on the status information:

[0147] In one implementation, the control valve is closed when the current time falls within the heating period; and opened when the current time falls outside the heating period. The heating period is a pre-defined time during which the centralized heating system provides heat.

[0148] In another implementation, the control valve is closed when the supply liquid temperature is greater than or equal to a first preset temperature; and the control valve is opened when the supply liquid temperature is less than a second preset temperature. The first preset temperature is greater than or equal to the second preset temperature. The first and second preset temperatures are critical values ​​used to distinguish whether the centralized heating system is in a heating state. When the supply liquid temperature is greater than or equal to the first preset temperature, the centralized heating system is considered to be in a heating state; when the supply liquid temperature is less than the second preset temperature, the centralized heating system is considered to be in a stopped heating state.

[0149] In another implementation, the status information includes the liquid supply temperature of the centralized heating system and the temperature of the second refrigerant flowing out of the control valve and the first heat exchange module. The step of controlling the operation of the control valve based on the status information includes: controlling the control valve to close when the liquid supply temperature and the second refrigerant temperature meet a preset condition; and controlling the control valve to open when the liquid supply temperature and the second refrigerant temperature do not meet the preset condition. The preset condition includes a temperature difference between the liquid supply temperature and the second refrigerant temperature greater than a preset temperature difference, or a liquid supply temperature greater than the second refrigerant temperature, where the preset temperature difference is greater than 0. The preset condition indicates that the centralized heating system can effectively increase the outlet temperature of the first heat exchange module.

[0150] In this embodiment, the above method helps to ensure that when the central heating system can effectively increase the outlet temperature of the first heat exchange module, the control valve is closed to allow the refrigerant to exchange heat with the central heating system through the second heat exchange module. When the central heating system cannot effectively increase the outlet temperature of the first heat exchange module, the control valve is opened to stop the refrigerant from exchanging heat with the central heating system through the second heat exchange module. This effectively reduces the water resistance of the second heat exchange module on the circulation rate and energy loss of the refrigerant, thereby effectively improving the energy efficiency of the system.

[0151] In other embodiments, the opening degree of the control valve may also be adjusted according to the liquid supply temperature of the central heating system or the difference between the liquid supply temperature of the central heating system and the temperature of the second refrigerant.
