Description

Technical Field

[0001] This invention relates to the field of heating technology, and in particular to a control method for an environmental control system, an environmental control system, and a storage medium. Background Technology

[0002] With the advancement of building carbon neutrality and the improvement of users' living standards, the forms of home air conditioning product combination systems are becoming increasingly diverse, and the choices for indoor heating are also increasing. For example, one or more terminals in a combination system can be configured in the same room, and the heating equipment in the combination system (such as heat pump systems and gas appliances) can deliver heat to multiple terminals, allowing the room to be heated through multiple terminals. However, currently, most systems rely on users manually selecting to turn on one or more terminals, as well as manually turning on gas appliances and / or heat pump systems. This lack of automation means that unnecessarily turning on one or more terminals can affect the heating effect of the heating equipment, thereby impacting the indoor heating effect. Similarly, failing to turn on gas appliances and / or heat pump systems in a timely manner can also affect the heating effect of the indoor space. Summary of the Invention

[0003] The main objective of this invention is to provide a control method, an environmental regulation system, and a storage medium for an environmental regulation system, aiming to solve the technical problem of poor indoor heating effect caused by low level of intelligence in indoor heating.

[0004] To achieve the above objectives, the present invention provides a control method for an environmental control system. The environmental control system includes a heat pump system, a gas equipment, a refrigerant circulation loop, and terminal equipment. The terminal equipment includes convective terminals and radiative terminals. Both the heat pump system and the gas equipment are configured to supply power to the terminal equipment. Both the heat pump system and the gas equipment are connected to the refrigerant circulation loop for heat exchange. The method includes:

[0006] Based on the indoor temperature, determine the target terminal that needs to be turned on in the terminal equipment, control the target terminal to be turned on, and obtain the first refrigerant temperature of the refrigerant circulation loop;

[0007] When the temperature of the first refrigerant meets the preset heat replenishment conditions, the gas equipment is started;

[0008] The preset heat replenishment condition indicates that the heat pump system is insufficient to provide heat to the target terminal.

[0009] In one embodiment, the preset heat replenishment condition includes the difference between the first refrigerant temperature and the first target refrigerant temperature of the heat pump system being less than a first preset value, or the difference between the first refrigerant temperature and the first target refrigerant temperature being less than the first preset value and lasting for a first preset duration.

[0010] In one embodiment, the step of determining the target terminal to be turned on among the terminal devices based on the indoor temperature and controlling the target terminal to turn on includes:

[0011] When the indoor temperature meets the first condition, it is determined that the target terminal includes the convection terminal and the radiant terminal, and the convection terminal and the radiant terminal are controlled to open; and / or,

[0012] When the indoor temperature does not meet the first condition, the target terminal is determined to be the radiant terminal, and the radiant terminal is controlled to turn on.

[0013] The first condition includes: the indoor temperature is less than a second preset value, or the difference between the indoor temperature and the set temperature of the target indoor space is less than a third preset value.

[0014] In one embodiment, after the step of controlling the activation of the convection terminal and the radiation terminal, the method further includes:

[0015] When the indoor temperature meets the second condition, the convection terminal is turned off;

[0016] The second condition includes that the difference between the indoor temperature and the corresponding set temperature is greater than or equal to a fourth preset value, wherein the fourth preset value is greater than the third preset value.

[0017] In one embodiment, after the step of starting the gas appliance, the method further includes:

[0018] The second target refrigerant temperature of the gas equipment is determined based on the first refrigerant temperature, the first rated heat capacity of the heat pump system, and the second rated heat capacity of the gas equipment.

[0019] The operation of the gas equipment is controlled according to the second target refrigerant temperature.

[0020] In one embodiment, the step of determining the second target refrigerant temperature of the gas appliance based on the first refrigerant temperature, the first rated heating capacity of the heat pump system, and the second rated heating capacity of the gas appliance includes:

[0021] Based on the first rated heat capacity and the second rated heat capacity, an adjustment coefficient is determined, and the temperature difference between the first refrigerant temperature and the first target refrigerant temperature of the heat pump system is determined.

[0022] The temperature adjustment value is determined based on the adjustment coefficient and the temperature difference value;

[0023] The temperature of the first refrigerant is adjusted according to the temperature adjustment value to obtain the second target refrigerant temperature.

[0024] In one embodiment, after the step of starting the gas appliance, the method further includes:

[0025] Obtain the temperature of the second refrigerant in the environmental control system;

[0026] When the temperature of the second refrigerant meets the third condition, the gas equipment is shut off;

[0027] The third condition includes the difference between the second refrigerant temperature and the third target refrigerant temperature of the environmental control system being greater than a fifth preset value, or the difference between the second refrigerant temperature and the third target refrigerant temperature being greater than the fifth preset value and lasting for a second preset duration.

[0028] In one embodiment, after the step of starting the gas appliance, the method further includes:

[0029] Acquire the spatial temperature of all target indoor spaces in the environmental control system;

[0030] Determine the temperature difference between each space temperature and the corresponding set temperature;

[0031] When all the temperature differences are greater than or equal to the fourth preset value, the gas equipment is turned off.

[0032] In one embodiment, after the step of starting the gas appliance, the method further includes:

[0033] Obtain the outdoor ambient temperature, and when the outdoor ambient temperature meets the fourth condition, turn off the gas equipment;

[0034] The fourth condition includes the outdoor ambient temperature being greater than a preset temperature threshold, or the outdoor ambient temperature being greater than a preset temperature threshold and lasting for a third preset duration.

[0035] In one embodiment, after the step of controlling the heat pump system to operate in a heat exchange mode, the method further includes:

[0036] Obtain the outdoor ambient temperature;

[0037] When the outdoor ambient temperature is lower than a preset low temperature threshold, the step of obtaining the indoor temperature of the target indoor space is performed.

[0038] In one embodiment, both the convection end and the radiation end are located in the refrigerant circulation loop, or the convection end is located in the heat pump system and the radiation end is located in the refrigerant circulation loop.

[0039] The present invention also provides an environmental control system, the environmental control system including a control unit, a power supply system and terminal devices, the terminal devices including convection terminals and radiation terminals, the control unit including a memory, a processor and a control program of the environmental control system stored in the memory and executable on the processor, the control program of the environmental control system being executed by the processor, and performing the steps of the control method of the environmental control system as described above.

[0040] The present invention also provides a computer-readable storage medium storing a control program for an environmental control system that can run on a processor, the control program being invoked by the processor to implement the steps of the environmental control system control method described above.

[0041] The present invention proposes one or more technical solutions, which have at least the following technical effects: The present invention controls the heat exchange mode of the heat pump system to provide energy to the terminal devices. Then, by obtaining the indoor temperature of the target indoor space where the terminal devices are located, the target terminal to be turned on is determined in the terminal devices according to the indoor temperature. Thus, it is possible to select to turn on the convection terminal and / or the radiation terminal in the terminal devices according to different indoor temperatures, without the need for the user to manually select the terminal to turn on, thereby improving the intelligence of indoor heating. Furthermore, since the number of target terminals activated changes after the target terminals are turned on, the corresponding heat exchange area also changes (the more target terminals activated, the larger the heat exchange area; the fewer target terminals activated, the smaller the heat exchange area). Therefore, after the target terminals are turned on, the heat pump system may not provide sufficient heat to the target terminals. Therefore, this invention obtains the first refrigerant temperature of the refrigerant circulation loop after the target terminals are turned on. When the first refrigerant temperature meets the preset heat replenishment conditions, the gas equipment is started. This enables the gas equipment to be started in a timely manner when the heat pump system is insufficient to heat the target terminals, so that the gas equipment can provide timely heat to the activated target terminals. This facilitates the improvement of the heating effect of the target indoor space and eliminates the need to manually select to turn on the gas equipment and / or the heat pump system, further improving the intelligence of indoor heating.

[0051] The objectives, features, and advantages of this invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0052] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] The main technical solution of this invention is as follows: The environmental control system includes an energy supply system and terminal devices. The energy supply system includes a heat pump system and a gas appliance. The terminal devices include convection terminals and radiant terminals. The energy supply system is configured to supply energy to the terminal devices. The environmental control system can automatically select to activate the radiant terminals and / or the convection terminals. Specifically, when the indoor temperature is less than a second preset value, or when the difference between the indoor temperature and the corresponding set temperature is less than a third preset value, the convection terminals and radiant terminals can be activated. When the indoor temperature is greater than the second preset value, and the difference between the indoor temperature and the corresponding set temperature is greater than or equal to the third preset value and less than the first preset value, only the radiant terminals can be activated.

[0054] In this embodiment of the invention, when heating an indoor space, the heat provided to the indoor space is adjusted based on the actual indoor temperature, rather than simply adjusting the temperature of the heat source (such as a gas appliance or heat pump system). Therefore, this embodiment adjusts the number of terminals opened in the indoor space based on the indoor temperature, allowing for more precise temperature control and improved user comfort. Furthermore, when the environmental control system simultaneously heats multiple indoor spaces, and the indoor temperatures and set temperatures of different spaces vary, the accuracy of temperature regulation for each indoor space can be improved by automatically adjusting the number of terminals opened in each individual space.

[0055] Furthermore, after the target terminal device is turned on, the first refrigerant temperature will be obtained. When the first refrigerant temperature meets the preset heat replenishment conditions, the gas equipment will be started. This enables the gas equipment to be turned on in time when the heat pump system is insufficient to heat the target terminal, so that the gas equipment can provide timely heat to the turned-on target terminal, thereby improving the heating effect of the indoor space. Moreover, there is no need to manually select to turn on the gas equipment and / or the heat pump system, further improving the intelligence of indoor heating.

The outdoor unit is connected to the hydraulic module for heat exchange through the refrigerant circulation loop. The hydraulic module and gas equipment provide energy to the radiant terminal through the refrigerant circulation loop, and the outdoor unit provides heat to the convective terminal through the refrigerant circulation loop.

The energy supply system includes a heat pump system and gas equipment. The heat pump system includes an outdoor unit, an indoor unit, a hydraulic module, and a refrigerant circulation loop. Both the convection terminal and the radiant terminal are connected to the refrigerant circulation loop for heat exchange. The refrigerant circulation loop is connected to the refrigerant circulation loop for heat exchange through the hydraulic module. The outdoor unit is connected to the indoor unit for heat exchange through the refrigerant circulation loop.

[0060] It should be noted that, in this embodiment of the invention, the environmental control system can be used to regulate the indoor temperature. Gas appliances and heat pump systems can provide heat to terminal devices, enabling these devices to heat the target indoor space where they are located.

[0061] The number of terminal devices may include one or more, and the terminal devices may be installed in different indoor spaces. For example, the environmental control system is set to regulate at least two indoor spaces, each indoor space is equipped with radiant terminals (such as radiators, underfloor heating, etc.) and convection terminals (such as fan coil units, duct indoor units, etc.).

[0062] In the environmental control system of the present invention, both the radiating terminal and the convective terminal can be located in the refrigerant circulation loop, or the convective terminal can be located in the heat pump system and the radiating terminal can be located in the refrigerant circulation loop.

[0063] Please refer to Figure 1 and Figure 2 , Figure 1 and Figure 2 In the environmental control system shown, both the radiant and convective terminals can be located in the refrigerant circulation loop. Please refer to [reference needed]. Figure 3 , Figure 3 In the environmental control system shown, the convection terminal is located in the heat pump system and the radiation terminal is located in the refrigerant circulation loop.

[0064] In this embodiment of the invention, the environmental control system can have various structures; please refer to [reference needed]. Figures 1-3 The environmental control system in this embodiment will be described.

[0065] Reference Figure 1The environmental control system shown includes an energy supply system, terminal equipment, heat exchange devices, and a refrigerant circulation loop. Both the convective and radiative terminals are connected to the refrigerant circulation loop for heat exchange. The energy supply system includes gas equipment and a heat pump system, which supply energy to the terminal equipment through the refrigerant circulation loop.

[0066] It should be noted that the environmental control system includes a heat pump system 100, a refrigerant circulation loop, a gas appliance 300, a heat exchange device 30, and terminal equipment 40. The heat pump system 100 can be a heat pump unit, and the terminal equipment 40 includes convective terminals 41 and radiant terminals 42. Please refer to... Figure 1 The structure of this environmental control system is described below:

[0067] The gas appliance 300 is connected to the heat exchange device 30, and the heat pump system 100 is connected to the heat exchange device 30 for heat exchange, such as... Figure 1 The convection terminal 41 shown can be a fan coil unit. The heat pump system 100 is used to regulate the temperature of the indoor space, and the gas appliance 300 can also be used to regulate the temperature of the indoor space. For example, when the heat pump system 100 is insufficient in providing heat, the gas appliance 300 can supplement the regulation of the indoor space temperature.

[0068] The heat generated by the heat pump system 100 and the gas appliance 300 can be transferred to the heat exchange device 30 in the refrigerant circulation loop 200, and the energy (e.g., heat) is transferred to the radiant terminal 42 and the convection terminal 41 through the heat exchange device 30 to heat the indoor space 50 through the radiant terminal 42.

[0069] The refrigerant in the refrigerant circulation loop 200 can be water. The heat pump system 100 absorbs heat from a low-grade heat source such as air by performing work with a compressor and transfers it to a medium such as water to produce hot water, which can then be used to regulate the indoor and outdoor ambient temperatures. The gas appliance 300 heats a medium such as water by burning fuel such as natural gas to produce hot water, thereby regulating the indoor ambient temperature. The heat exchange device 30 is used to balance the flow and pressure of the environmental control system. The heat exchange device 30 can be a coupling tank or a water container such as a small buffer tank.

[0070] There can be multiple terminal devices 40, and the terminal devices 40 can be distributed in different indoor spaces 50.

[0071] The radiant terminal 42 can be a floor heating coil, radiant panel, capillary network, etc., and can be installed on the wall surface of the indoor space (including walls and / or floors and / or ceilings, etc.). The convection terminal 41 can also be a fan coil unit, etc. For example, each indoor space can be equipped with a radiant terminal and a convection terminal separately, and other types of terminals can also be installed.

Controlling the heat pump system to operate in heating mode, for example, as... Figure 1 The environmental control system shown can be in heating mode, which is the operating mode of a heat pump unit.

Both the heat pump system 100 and the gas equipment 300 can deliver heated water to the heat exchange device 30. The heat exchange device 30 can transfer heat to each radiant terminal and each convective terminal to provide heat to the target indoor space where the terminal equipment is located. Figure 1 There are multiple indoor spaces (50 in total). In this implementation, the number of indoor spaces is not limited. Water passing through the indoor spaces can return to the heat pump system.

[0074] In other embodiments, please refer to Figure 2 The environmental control system shown includes an energy supply system, terminal equipment, heat exchange devices, and a refrigerant circulation loop. The energy supply system includes a heat pump system and gas equipment. The heat pump system includes an outdoor unit, a hydraulic module, and a refrigerant circulation loop. The convective terminals are connected to the refrigerant circulation loop for heat exchange, and the radiant terminals are connected to the refrigerant circulation loop for heat exchange. The outdoor unit is connected to the hydraulic module for heat exchange through the refrigerant circulation loop. The hydraulic module and gas equipment provide energy to the radiant terminals through the refrigerant circulation loop, and the outdoor unit provides heat to the convective terminals through the refrigerant circulation loop.

[0075] It should be noted that the environmental control system includes a heat pump system 100, a refrigerant circulation loop 200, a gas appliance 300, and a terminal device 40. The environmental control system also includes a heat exchange device 30. The heat pump system 100 includes an outdoor unit 110, a refrigerant circulation loop 120, and a hydraulic module 400. A radiant terminal 42 is provided on the refrigerant circulation loop, and a convection terminal 41 is provided on the refrigerant circulation loop 120.

[0076] The heat pump system 100, consisting of the outdoor unit 110 and the hydraulic module 400, absorbs heat from low-grade heat sources such as air through the work of the compressor and transfers it to a medium such as water to produce hot water. The outdoor unit 110 can also provide heat to the convection terminal through the refrigerant circulation loop 120 to heat the indoor space. The hydraulic module 400 can transfer heat to the radiant terminal through the heat exchange device and the refrigerant circulation loop to heat the indoor space.

[0077] Radiant terminal 42 regulates the indoor environment by utilizing the cooling or heating output of the flowing refrigerant. Convection terminal 41 regulates the indoor environment by utilizing the cooling or heating output of the flowing refrigerant. Heat exchange device 30 is located downstream of the water supply of hydraulic module 400; terminal equipment 40 is connected downstream of hydraulic module 400 and gas equipment 300. Heat exchange device 30 can be a mixing device, such as a coupling tank, a small buffer tank, or a water pipe assembly.

[0078] The refrigerant circulation loop 200 is filled with refrigerant, which can flow within the refrigerant circulation system 200. In this embodiment, the refrigerant is water. In other embodiments, the refrigerant may also be an aqueous solution of sodium chloride or calcium chloride salt, or an aqueous solution of organic compounds such as ethylene glycol or glycerol, etc.

[0079] Outdoor unit 110 can be a multi-split outdoor unit. Outdoor unit 110 can discharge refrigerant into refrigerant circulation loop 120.

[0080] The refrigerant circulation loop 120 is connected to the refrigerant circulation loop 200 via a hydraulic module 400 for heat exchange. Specifically, in this embodiment, the hydraulic module 400 includes a heat exchange module and a heat exchanger. The heat exchange module and the heat exchanger are connected for heat exchange, and the refrigerant in the refrigerant circulation loop can exchange heat with the refrigerant in the heat exchanger when it flows through the heat exchange module.

[0081] Figure 2 The middle arrow indicates the direction of refrigerant flow. The refrigerant can be water. Both the heat pump system 100 and the gas appliance 300 can deliver heated water to the heat exchange device 30. The heat exchange device 30 then distributes heat to each radiant terminal to provide warmth to the indoor space where the radiant terminals are located. Figure 2 There are multiple indoor spaces (50 in total). In this implementation, the number of indoor spaces is not limited. Water passing through the indoor spaces can return to the heat pump system.

[0082] Reference Figure 2 ,like Figure 2 Based on the environmental control system shown, the control method of the environmental control system includes: controlling the heat pump system to operate in heat exchange mode to obtain the indoor temperature of the target indoor space; determining the target terminal to be turned on among the terminal devices according to the indoor temperature, controlling the target terminal to turn on, and obtaining the first refrigerant temperature of the refrigerant circulation loop; when the first refrigerant temperature meets the preset heat compensation conditions, starting the gas equipment. For example, as... Figure 2 The environmental control system shown can output refrigerant from the hydraulic module in the heat pump system to the refrigerant circuit when the heat pump system is in heating mode.

[0083] In other embodiments, please refer to Figure 3The environmental control system shown includes an energy supply system, terminal equipment, heat exchange devices, and a refrigerant circulation loop. The energy supply system includes a heat pump system and gas equipment. The heat pump system includes an outdoor unit, an indoor unit, a hydraulic module, and a refrigerant circulation loop. Both the convection terminal and the radiant terminal are connected to the refrigerant circulation loop for heat exchange. The refrigerant circulation loop is connected to the refrigerant circulation loop for heat exchange through the hydraulic module. The outdoor unit is connected to the indoor unit for heat exchange through the refrigerant circulation loop.

[0084] It should be noted that the environmental control system includes a heat pump system 100, a refrigerant circulation loop 200, a gas appliance 300, a heat exchange device 30, and terminal equipment 40. The heat pump system 100 includes an outdoor unit 110, an indoor unit 11, a refrigerant circulation loop 120, and a hydraulic module 400. The refrigerant circulation loop is equipped with a radiant terminal 42 and a convection terminal 41.

[0085] The refrigerant circulation loop 200 also includes a fluid regulation module 23, a first refrigerant circulation branch 201, and a second refrigerant circulation branch 202. The fluid regulation module 23 can drive the flow of refrigerant in the system. Specifically, the fluid regulation module 23 can be used to control the inflow or cessation of refrigerant into each terminal device 40. The fluid regulation module 23 includes at least two sub-regulation modules, each corresponding to a terminal device 40. Each sub-regulation module can be configured to control the flow rate of refrigerant in its corresponding terminal device 40. When a sub-regulation module is open, refrigerant is allowed to flow into the corresponding terminal device 40; when a sub-regulation module is closed, refrigerant flow into the corresponding terminal device 40 is stopped. In this embodiment, the fluid regulation module 23 is a manifold, and the sub-regulation modules are the water distribution valves within the manifold.

[0086] The first circulation branch 201 connects the heat exchange device 30 and the gas equipment 300. The second circulation branch 202 is connected to the terminal device 40, the fluid regulation module 23, the heat exchange device 30, and the hydraulic module 400. The fluid control module can control the fluid regulation module 23.

[0087] The refrigerant discharged from the hydraulic module 400 flows into the heat exchange device 30. The refrigerant flowing out of the heat exchange device 30 sequentially passes through the first branch of the fluid regulating module 23, the terminal device 40, and the second branch of the fluid regulating module 23 before flowing back to the hydraulic module 400, thus achieving the circulation of the refrigerant. The refrigerant discharged from the gas appliance 300 flows into the heat exchange device 30. The refrigerant in the heat exchange device 30 can flow back to the gas appliance 300 and can also flow through the first branch of the fluid regulating module 23, the terminal device 40, and the second branch of the fluid regulating module 23 before flowing into the hydraulic module 400. The flow rate of the refrigerant from the gas appliance 300 to the heat exchange device 30 is equal to the flow rate of the refrigerant from the heat exchange device 30 to the gas appliance 300. Specifically, the refrigerant flowing from the hydraulic module 400 into the heat exchange device 30 and the refrigerant flowing from the gas equipment 300 into the heat exchange device 30 can exchange heat inside the heat exchange device 30. After heat exchange, the refrigerant can flow back to the gas equipment 300 and can flow to the first branch of the fluid regulation module 23, the terminal device 40 and the second branch of the fluid regulation module 23 before flowing into the hydraulic module 400.

[0088] Terminal equipment 40 regulates the indoor environment by utilizing the cooling or heating output of the flowing refrigerant. Terminal equipment 40 includes radiant terminals 42 and convective terminals 41. For example... Figure 3 The environmental control system shown has both the radiant terminal 42 and the convection terminal 41 connected to the refrigerant circulation loop 200, specifically to the second circulation branch 202 of the refrigerant circulation loop 200. The convection terminal 41 can be an indoor unit in a duct, etc.

[0089] The heat pump system also includes an outdoor unit 110 and at least two indoor units 11. The outdoor unit 110 can discharge refrigerant into the refrigerant circulation loop 120, and the outdoor unit 110 can be a multi-split outdoor unit. The indoor units 11 are connected to the refrigerant circulation loop 120, and the indoor units can be multi-split indoor units. Each indoor unit 11 includes an indoor heat exchanger and a corresponding indoor fan. Different indoor units 11 are located in different indoor spaces. Each indoor unit 11 can be associated with at least one terminal device 40, and the indoor unit 11 and its associated terminal device 40 are located in the same indoor space 50. The indoor space 50 includes the terminal device 40, the wired control terminal 500, and the indoor units 11. Figure 3 The environmental control system may include multiple indoor units 1 to 4, wired controllers 1 to 4, and may also include other multiple indoor units and wired controllers. This embodiment does not specifically limit this.

[0090] The refrigerant circulation loop 120 is connected to the refrigerant circulation loop 200 via a hydraulic module 400 for heat exchange. A control valve 122 is also provided on the refrigerant circulation loop, which can be used to adjust the overall refrigerant quantity of at least two indoor units 11. Specifically, in this embodiment, the hydraulic module 400 includes a heat exchange module and a heat exchanger. The heat exchange module and the heat exchanger are connected for heat exchange, and the refrigerant in the refrigerant circulation loop can exchange heat with the refrigerant in the heat exchanger when it flows through the heat exchange module.

[0091] Furthermore, such as Figure 3 In one embodiment of the environmental control system shown, each indoor space regulated by the system may be equipped with a wired controller 300. The outdoor unit 110, the circulation pump, the gas appliance 300, the fluid regulation module 23, and the wired controller 300 can be connected via signal lines. The circulation pump is used to drive the flow of refrigerant. The wired controller 300 in each indoor space is correspondingly bound to the terminal device 40 in the indoor space and the sub-regulation module connected to the terminal device 40. The wired controller 300 can control at least one of the following: the liquid supply temperature of the sub-regulation module, the circulation pump, the gas appliance 300, the fluid regulation module 23, the outdoor ambient temperature of the indoor space, etc.

[0092] Reference Figure 3 ,exist Figure 3 Based on the environmental control system shown, the control method of the environmental control system includes: controlling the heat pump system to operate in heat exchange mode to obtain the indoor temperature of the target indoor space; determining the target terminal to be turned on among the terminal devices according to the indoor temperature, controlling the target terminal to turn on, and obtaining the first refrigerant temperature of the refrigerant circulation loop; when the first refrigerant temperature meets the preset heat compensation conditions, starting the gas equipment. For example, as... Figure 3 The environmental control system shown can output refrigerant from the hydraulic module in the heat pump system to the refrigerant circuit when the heat pump system is in heating mode. Figure 3 In the environmental control system shown, both the convection terminal and the radiation terminal are connected to the refrigerant circulation loop.

[0093] The control method of the environmental control system in the embodiments of the present invention can be applied to Figure 1 The environmental control system shown can also be applied to Figure 2 The environmental control system shown can also be applied to Figure 3 The environmental control systems shown can all control the heat pump system's operation in heat exchange mode to obtain the indoor temperature of the target indoor space; determine the target terminal equipment to be turned on based on the indoor temperature, control the target terminal to turn on, and obtain the first refrigerant temperature in the refrigerant circulation loop; when the first refrigerant temperature meets the preset heat compensation conditions, the gas equipment is started. The difference lies in... Figure 1The convection and radiation terminals in the environmental control system shown are both located in the refrigerant circulation loop, and the environmental control system does not include a refrigerant circulation loop. Figure 2 In the environmental control system shown, the radiant terminal is located on the refrigerant circulation loop, and the convective terminal is located on the refrigerant circulation loop of the heat pump system. Figure 3 The heat pump system in the environmental control system shown includes a refrigerant circulation loop, and heat exchange can be performed between the refrigerant circulation loop and the refrigerant-carrying circulation loop. Both the convection terminal and the radiation terminal are located on the refrigerant circulation loop.

[0094] In other embodiments, Figures 1-3 The environmental control systems shown can all utilize gas-fired equipment for supplemental heating and can all obtain the refrigerant temperature in the refrigerant circulation loop. Specifically, the refrigerant temperature is obtained by detecting the refrigerant temperature in the circulation loop. Figure 1 In the environmental control system shown, the refrigerant can be output from the heat pump system to the refrigerant circulation loop. Figure 2 and Figure 3 In the environmental control system shown, the refrigerant can be output from the hydraulic module of the heat pump system to the refrigerant circulation loop.

[0095] Based on this, the present invention proposes a control method for an environmental control system according to a first embodiment, please refer to... Figures 1-4 The environmental control system includes a heat pump system, gas equipment, a refrigerant circulation loop, and terminal equipment. The terminal equipment includes convective terminals and radiant terminals. The heat pump system and gas equipment are both powered by the terminal equipment. Both the heat pump system and gas equipment are connected to the refrigerant circulation loop for heat exchange. The control method of the environmental control system includes steps S10 to S30:

[0096] Step S10: Control the heat pump system to operate in heat exchange mode and obtain the indoor temperature of the target indoor space;

[0097] It should be noted that the environmental control system can be used to generate heat and provide it to the indoor space. Specifically, both heat pump systems and gas appliances can be used to generate heat to power the terminal devices. When the heat pump system and / or gas appliance operate in heat exchange mode, it can provide heat or cooling to the terminal devices. Heat exchange modes include heating mode and cooling mode. In this embodiment, both the heat pump system and the gas appliance operate in heating mode.

[0098] The target indoor space is an indoor space with heat exchange requirements. For example, if a user turns on the environmental control system in a certain indoor space for cooling or heating, then that indoor space is the target indoor space. At least one convection terminal and / or at least one radiant terminal are installed in the target indoor space.

[0099] Indoor temperature is the current actual temperature of the target indoor space. Indoor temperature can be obtained by a temperature sensor or other device that can acquire temperature, which is pre-installed in the target indoor space.

[0100] The environmental control system may include multiple terminal devices, which can be distributed in different and / or the same indoor spaces to provide heating for multiple indoor spaces. That is, each indoor space can be heated through convection and radiant terminals when heat exchange is required. In this embodiment, the temperature of any target indoor space where any terminal device is located can be automatically adjusted.

[0101] After controlling the heat exchange mode of the energy supply system, the control method of the environmental conditioning system further includes: acquiring the outdoor ambient temperature, and when the outdoor ambient temperature is lower than a preset low temperature threshold, acquiring the indoor temperature of the target indoor space.

[0102] Outdoor ambient temperature refers to the temperature of the outdoor environment. When the outdoor ambient temperature is lower than the preset low temperature threshold, it indicates that the outdoor ambient temperature is relatively low, which means that the target indoor space may also need heating. Therefore, the indoor temperature of the target indoor space can be obtained to determine whether the target indoor space needs heating or to increase heating. The preset low temperature threshold can be set based on actual conditions. For example, the preset low temperature threshold can be 3°C, etc. This embodiment does not make a specific limitation on this.

[0103] For example, the heat pump system in the energy supply system is controlled to operate in heat exchange mode, and the outdoor ambient temperature is obtained. When the outdoor ambient temperature is lower than a preset low temperature threshold, the indoor temperature of any target indoor space is obtained, so as to determine which terminals in the terminal equipment need to be turned on based on the indoor temperature.

[0104] Step S20: Determine the target terminal to be turned on in the terminal equipment according to the indoor temperature, control the target terminal to be turned on, and obtain the first refrigerant temperature of the refrigerant circulation loop.

[0105] It should be noted that the target terminal refers to the terminal that needs to be activated. The target terminal can be a convective terminal and / or a radiative terminal. The target terminal to be activated can be selected based on the indoor temperature. After the target terminal is activated, it can supply heat to the corresponding target indoor space. Each target indoor space can select the target terminal to be activated in the terminal equipment list. Different target indoor spaces can have different or the same target terminal activated. The target terminal can be all the terminal equipment in the target indoor space or a portion of the terminal equipment in the target indoor space.

[0106] The terminal equipment is equipped with automatically controlled valves, which can be used to control the opening and closing of the terminal equipment. For example, both radiant and convection terminals can be equipped with automatically controlled valves. For instance, the indoor temperature can be used to determine whether the radiant and / or convection terminals need to be activated. Since heat pump systems provide a larger flow rate and higher efficiency compared to gas appliances, the heat pump system can be started in heating mode first. When the heat provided by the heat pump system is insufficient, the gas appliance can be activated to supplement the heating.

[0107] In one feasible embodiment, step S20 includes:

[0108] Step S21: When the indoor temperature meets the first condition, determine that the target terminal includes both convection terminal and radiation terminal, and control the convection terminal and radiation terminal to be turned on.

[0109] The first condition includes: the indoor temperature is less than the second preset value, or the difference between the indoor temperature and the set temperature of the target indoor space is less than the third preset value.

[0110] It should be noted that the first condition indicates that the heat received by the indoor space is insufficient. In other words, when the indoor temperature meets the first condition, it means that the heat currently received by the target indoor space cannot meet the needs of the target indoor space.

[0111] The first condition includes an indoor temperature lower than a second preset value, or the difference between the indoor temperature and the set temperature of the target indoor space is lower than a third preset value. In other embodiments, the first condition may further include an indoor temperature lower than the second preset value, or the difference between the indoor temperature and the corresponding set temperature being lower than the third preset value, when the outdoor ambient temperature is lower than a preset low temperature threshold; in other embodiments, the first condition may further include an indoor temperature lower than the second preset value, and the difference between the indoor temperature and the corresponding set temperature being lower than the third preset value, when the outdoor ambient temperature is lower than a preset low temperature threshold.

[0112] It should be noted that the set temperature is the target temperature that the target indoor space needs to reach. Different target indoor spaces can have different set temperatures. The second preset value is the highest temperature threshold required for heating in the target indoor space. If the indoor temperature is lower than the second preset value, it indicates that the target indoor space is too cold and needs heating. The third preset value is the highest temperature difference threshold required for heating in the target indoor space. When the difference between the indoor temperature and the set temperature is less than the third preset value, it indicates that the target indoor space needs heating. The difference between the indoor temperature and the set temperature can be negative, positive, or 0. The second and third preset values, as well as the set temperature, can all be set based on actual conditions.

[0113] When the outdoor ambient temperature is lower than the preset low temperature threshold, it means that the outdoor ambient temperature is also very low. The target indoor space is affected by the low temperature, and the temperature of the target indoor space will also be relatively low. Therefore, in a low temperature environment, the target indoor space may need to turn on the convection terminal and the radiant terminal for heating.

[0114] Step S22: When the indoor temperature does not meet the first condition, determine that the target terminal is a radiant terminal and control the radiant terminal to turn on;

[0115] It should be noted that when the indoor temperature does not meet the first condition, it means that the target indoor space is receiving a lot of heat. Therefore, the radiant terminal can be turned on and the convection terminal can be turned off to ensure the comfort of heating in the target indoor space. The convection terminal can be kept off or adjusted from the on state to the off state, thereby reducing the amount of heating required in the target indoor space and thus reducing the amount of heat.

[0116] If the difference between the indoor temperature and the set temperature is greater than or equal to the third preset value and less than the first preset value, it indicates that the difference between the indoor temperature and the set temperature of the target indoor space is small, but there is still a difference between the indoor temperature and the set temperature, or the target indoor space still needs to be heated to maintain the indoor temperature.

[0117] For example, when the indoor temperature is greater than a second preset value, or when the difference between the indoor temperature and the set temperature of the target indoor space is less than a third preset value, the target terminal is determined to be a radiant terminal, and the radiant terminal is controlled to turn on. Meanwhile, the convection terminal is controlled to remain in the off state.

[0118] In other embodiments, when the indoor temperature is greater than a second preset value, the difference between the indoor temperature and the set temperature of the target indoor space is greater than or equal to a third preset value, and the difference between the indoor temperature and the set temperature is less than a preset temperature difference threshold, the target terminal is determined to be a radiant terminal, and the radiant terminal is controlled to turn on. The preset temperature difference threshold is greater than the third preset value.

[0119] When the difference between the room temperature and the set temperature is small, only radiant heating is turned on to ensure heating comfort.

[0120] The control of the target terminal can be implemented by determining that the target terminal includes both convective and radiative terminals when the indoor temperature meets the first condition, and then controlling the opening of both convective and radiative terminals. Alternatively, it can be implemented by determining that the target terminal is a radiative terminal when the indoor temperature does not meet the first condition, and then opening the radiative terminal.

[0121] This invention, through controlling the heat exchange mode of the heat pump system, obtains the indoor temperature of the target indoor space. When the indoor temperature meets a first condition, both the convection and radiant terminals are activated. In other words, when the target indoor space lacks sufficient heat, this invention can simultaneously activate both convection and radiant terminals to quickly meet the heat demand of the target indoor space, eliminating the need for manual selection by the user and improving the intelligence of indoor heating. Furthermore, since indoor temperature accurately and directly reflects the heating status of the target indoor space, determining whether to activate the convection and radiant terminals based on indoor temperature allows for more precise temperature adjustment of the target indoor space, thereby improving the heating effect.

[0122] In a possible embodiment, step S211 is further included after step S21:

[0123] Step S211: If the indoor temperature meets the second condition, shut off the convection terminal;

[0124] The second condition includes that the difference between the indoor temperature and the corresponding set temperature is greater than or equal to the fourth preset value, and the fourth preset value is greater than the third preset value.

[0125] It should be noted that when both the convection and radiant heating terminals are on, if the difference between the detected indoor temperature and the set temperature exceeds the fourth preset value, it indicates that the indoor temperature may be higher than the set temperature. In this case, the convection terminal can be turned off, and the target indoor space can be heated through the radiant heating terminal. The convection terminal can be a ducted indoor unit or a fan coil unit.

[0126] For example, for the target indoor space of the environmental control system, if the difference between the space temperature of the target indoor space and the corresponding set temperature is greater than a fourth preset value, the convection terminal is turned off, and heating can be provided through the radiant terminal. This can improve the user's comfort when heating the target indoor space. In other embodiments, the second condition can also be that the indoor temperature is greater than a preset temperature value. The preset temperature value can be customized. When the indoor temperature is greater than the preset temperature value, it indicates that the temperature of the target indoor space is high, and even if only the radiant terminal is turned on, it will not affect the heating effect of the target indoor space.

[0127] Step S30: When the temperature of the first refrigerant meets the preset heat replenishment conditions, start the gas equipment;

[0128] The preset heat replenishment condition indicates that the heat pump system is not providing enough heat to the target terminal.

[0129] In one embodiment, the preset heat replenishment conditions include the difference between the first refrigerant temperature and the first target refrigerant temperature of the heat pump system being less than a first preset value, or the difference between the first refrigerant temperature and the first target refrigerant temperature being less than the first preset value and lasting for a first preset duration.

[0130] It should be noted that the energy supply system also includes gas equipment, which is connected to the refrigerant circulation loop for heat exchange. The temperature of the first refrigerant can be detected from the refrigerant circulation loop, for example, it can be detected from the pipes connected to the terminal equipment on the refrigerant circulation loop.

[0131] When the actual energy (e.g., heat) provided by the heat pump system may be insufficient to regulate the temperature of the target indoor space to the set temperature, gas equipment can be activated for auxiliary heating.

[0132] The first refrigerant temperature can be the current outlet water temperature of the heat pump system, and the preset heat replenishment condition indicates that the heat pump system is not supplying enough heat. The difference between the first refrigerant temperature and the first target refrigerant temperature can be negative, 0, or positive; this embodiment does not limit this. The first preset value and the first preset duration can be set based on actual conditions.

[0133] If the difference between the first refrigerant temperature and the first target refrigerant temperature is less than a first preset value, or if the difference between the first refrigerant temperature and the first target refrigerant temperature is less than the first preset value and remains less than the first preset value for a first preset duration, it indicates that the heat pump system's heating supply is insufficient, requiring supplemental heating from a gas-fired appliance. In this embodiment, when the difference between the refrigerant temperature and the first target refrigerant temperature is less than the first preset value, or when the difference between the first refrigerant temperature and the first target refrigerant temperature is less than the first preset value, the gas-fired appliance is promptly activated to provide timely supplemental heating. This allows the environmental control system to quickly adjust the temperature of the target indoor space in a low-temperature environment while ensuring energy efficiency, enabling the target indoor space to quickly reach its set temperature.

[0134] For example, a first refrigerant temperature and a first target refrigerant temperature of the heat pump system are obtained. If the difference between the first refrigerant temperature and the first target refrigerant temperature is less than a first preset value, or if the difference between the first refrigerant temperature and the first target refrigerant temperature is less than the first preset value, the gas appliance is controlled to start. If the difference between the first refrigerant temperature and the first target refrigerant temperature is less than the first preset value, the gas appliance may not need to be started.

[0135] In this embodiment of the invention, the heat pump system in the environmental control system is first controlled to operate in heating mode, and the temperature of the first refrigerant is obtained. When the temperature of the first refrigerant meets the preset heat compensation conditions, the gas equipment is controlled to start. This enables the gas equipment to be automatically turned on when the heat pump system's heat supply is insufficient, eliminating the need for manual selection to turn on the gas equipment and / or the heat pump system. This avoids turning on the gas equipment when the heat pump system's heat supply is sufficient, or avoiding not turning on the gas equipment for heat compensation when the heat pump system's heat supply is insufficient. This improves the automation level of combined heating of gas equipment and heat pump system, thereby providing users with a comfortable heating experience.

[0136] It should also be noted that if the heat pump system is operating in heating mode within the environmental control system, but the gas appliances are still off, the first target refrigerant temperature of the heat pump system can be determined based on the third target refrigerant temperature of the environmental control system. For example, the third target refrigerant temperature can be used as the first target refrigerant temperature. The third target refrigerant temperature is the target value of the refrigerant temperature flowing out of the environmental control system.

[0137] The third target refrigerant temperature of the environmental control system can be determined based on the set temperature of the target indoor space. For example, the highest set temperature in each target indoor space can be selected as the third target refrigerant temperature. The third target refrigerant temperature can also be adjusted. For example, the difference between the set temperature and the corresponding indoor temperature in each target indoor space can be calculated. The third target refrigerant temperature can be adjusted according to the largest difference. For example, when the difference is greater than a preset adjustment threshold, the third target refrigerant temperature can be increased; when the difference is less than the preset adjustment threshold, the third target refrigerant temperature can be decreased. It can be understood that the larger the difference, the greater the heating demand, and the smaller the difference, the smaller the heating demand. The larger the difference, the greater the third target refrigerant temperature can be, and the smaller the difference, the smaller the third target refrigerant temperature can be.

[0138] For example, such as Figure 1 The environmental control system shown can detect the temperature of the refrigerant in the pipe between the heat pump system 100 and the heat exchange device 30 to detect whether the refrigerant temperature output by the heat pump system reaches the first target refrigerant temperature; it can detect the refrigerant temperature in the pipe between the gas appliance 300 and the heat exchange device 30 to detect whether the refrigerant temperature output by the gas appliance reaches the second target refrigerant temperature; and it can detect the temperature of the pipe between the heat exchange device 30 and the terminal equipment to detect whether the refrigerant temperature output by the environmental control system reaches the third target refrigerant temperature.

[0139] For example, such as Figure 2 and Figure 3The environmental control system shown can detect the refrigerant temperature in the pipe between the hydraulic module 400 and the fluid control module 23 to determine whether the temperature output by the heat pump system reaches the first target refrigerant temperature. It can also detect the refrigerant temperature in the pipe between the fluid control module 23 and the terminal device 40 to determine whether the refrigerant temperature output by the environmental control system reaches the third target refrigerant temperature. Furthermore, it can detect the refrigerant temperature in the pipe between the gas appliance 300 and the heat exchange device 30 to determine whether the refrigerant temperature output by the gas appliance reaches the second target refrigerant temperature.

[0140] This invention controls the heat exchange mode of the heat pump system to supply energy to the terminal devices. By acquiring the indoor temperature of the target indoor space, the target terminal to be turned on is determined in the terminal devices based on the indoor temperature. This allows the terminal devices to select to turn on convection terminals and / or radiant terminals according to different indoor temperatures, eliminating the need for users to manually select the terminals to turn on and improving the intelligence of indoor heating. Furthermore, since the number of target terminals activated changes after the target terminals are turned on, the corresponding heat exchange area also changes (the more target terminals activated, the larger the heat exchange area; the fewer target terminals activated, the smaller the heat exchange area). Therefore, after the target terminals are turned on, the heat pump system may not provide sufficient heat to the target terminals. Thus, this embodiment of the invention obtains the first refrigerant temperature of the refrigerant circulation loop after the target terminals are turned on. When the first refrigerant temperature meets the preset heat replenishment conditions, the gas equipment is started. This enables the gas equipment to be turned on in a timely manner when the heat pump system is insufficient to heat the target terminals, thereby improving the heating effect of the target indoor space. Moreover, it eliminates the need to manually select to turn on the gas equipment and / or the heat pump system, further improving the intelligence of indoor heating.

[0141] In one possible embodiment, after step S30, the method further includes:

[0142] Step S31: Determine the second target refrigerant temperature of the gas equipment based on the first refrigerant temperature, the first rated heat capacity of the heat pump system, and the second rated heat capacity of the gas equipment.

[0143] Step S32: Control the operation of the gas equipment according to the second target refrigerant temperature.

[0144] It should be noted that the first rated heating capacity refers to the maximum heating capacity that the heat pump system can provide under standard operating conditions. The first rated heating capacity can be the rated nominal capacity of the heat pump system. The second rated heating capacity refers to the maximum heating capacity that the gas appliance can provide under standard operating conditions. The second rated heating capacity can be the rated nominal capacity of the gas appliance. The standard operating conditions of the heat pump system or gas appliance refer to the conditions that allow the heat pump system or gas appliance to operate normally, and may include standard temperature, humidity, or standard operating pressure range, etc.

[0145] The second target refrigerant temperature refers to the target value of the refrigerant temperature flowing out of the gas equipment after the gas equipment is turned on. The second target refrigerant temperature can be the second target refrigerant temperature of the gas equipment.

[0146] After determining the second target refrigerant temperature, the operation of the gas equipment can be controlled based on this temperature. For example, the output refrigerant temperature of the gas equipment can be adjusted by regulating the natural gas proportional valve, the number of burner ignitions, and / or the amount of air circulation. When the second target refrigerant temperature is higher than the current output refrigerant temperature, the output of the gas equipment can be increased by opening the natural gas proportional valve wider, increasing the number of burner ignitions, and / or increasing air circulation. Conversely, the output of the gas equipment can be reduced by decreasing the natural gas proportional valve, decreasing the number of burner ignitions, and / or reducing air circulation.

[0147] For example, a first target refrigerant temperature of the heat pump system is obtained; a second target refrigerant temperature is determined based on the difference between the first refrigerant temperature and the first target refrigerant temperature, a first rated heating capacity, and a second rated heating capacity; and the operation of the gas equipment is controlled based on the second target refrigerant temperature. This facilitates the rapid increase of the output temperature of the environmental control system.

[0148] In other embodiments, after the gas equipment is turned on, the operation of the gas equipment can also be controlled according to the preset target refrigerant temperature or preset heating power.

[0149] In a feasible embodiment, step S31 further includes:

[0150] Step S311: Determine the adjustment coefficient based on the first rated heat capacity and the second rated heat capacity, and determine the temperature difference between the refrigerant temperature and the first target refrigerant temperature of the heat pump system.

[0151] Step S312: Determine the temperature adjustment value based on the adjustment coefficient and the temperature difference value;

[0152] Step S313: Adjust the refrigerant temperature according to the temperature adjustment value to obtain the second target refrigerant temperature.

[0153] It should be noted that the adjustment factor is the product of the first factor and the second factor. The first factor is the ratio of the first rated heating capacity to the second rated heating capacity. The first factor can be used to describe the ratio of the rated nominal capacity of the heat pump system to the rated nominal capacity of the gas equipment. In other embodiments, the adjustment factor can also be the ratio of the first rated heating capacity to the second rated heating capacity.

[0154] The second coefficient can be determined based on the water flow rate provided by the heat pump system and the water flow rate provided by the gas equipment. It can be set according to actual conditions, and this embodiment does not impose specific limitations. In the environmental control system, the smaller the water flow rate provided by the gas equipment, the larger the second coefficient. For example, the preset heating flow rate can be set to 4. In this embodiment, when the gas equipment is not yet turned on, the first target refrigerant temperature of the heat pump system is the third target refrigerant temperature of the environmental control system, and the refrigerant temperature of the heat pump system is the system refrigerant temperature of the environmental control system.

[0155] The temperature adjustment value is the additional temperature that the gas-fired equipment needs to adjust when the current temperature of the environmental control system is the refrigerant temperature. The temperature adjustment value is the product of the adjustment coefficient and the temperature difference value.

[0156] A larger second rated heating capacity means more heat the gas-fired equipment can provide in a short time, allowing it to quickly reach the second target refrigerant temperature and rapidly heat the target indoor space. Conversely, a smaller second rated heating capacity means less heat can be provided in a short time, requiring a longer time to reach the target refrigerant temperature and consequently, a longer time for the target indoor space to reach the set temperature. Therefore, a smaller second rated heating capacity necessitates a higher second target refrigerant temperature setting to ensure the gas-fired equipment can quickly reach the set temperature. Conversely, a larger second rated heating capacity allows for a lower second target refrigerant temperature setting, achieving faster heating of the target space with lower operating costs. Thus, for example, a larger second rated heating capacity allows for a lower set second target refrigerant temperature, and vice versa.

[0157] For example, steps S311 to S313 include: obtaining a second coefficient, calculating the ratio of the first rated heat capacity to the second rated heat capacity to obtain a first coefficient, calculating the product of the first coefficient and the second coefficient to obtain an adjustment coefficient, calculating the difference between the first refrigerant temperature and the first target refrigerant temperature to obtain a temperature difference value, calculating the product of the adjustment coefficient and the temperature difference value to obtain a temperature adjustment value, and calculating the sum of the temperature adjustment value and the refrigerant temperature to obtain a second target refrigerant temperature.

[0158] For example, the first target refrigerant temperature can be calculated using the following formula:

[0159]

[0160] Where TWs_GB is the second target refrigerant temperature, G is the second coefficient, Qwhrating is the first rated heating capacity, and Qgbrating is the second rated heating capacity. To adjust the coefficient, TWs is the first coefficient, TW1 is the first target refrigerant temperature, and TW2 is the first refrigerant temperature.

[0161] This embodiment utilizes the rated capacity of the gas equipment and the heat pump system, the adjustment coefficient and temperature difference of the gas equipment, and the refrigerant temperature to calculate the second target refrigerant temperature of the gas equipment. This allows for accurate calculation of the second target refrigerant temperature of the gas equipment, ensuring that the target indoor temperature can be quickly reached in low-temperature environments and precisely adjusting the heating capacity output of the gas equipment. This improves the energy efficiency of the gas equipment and reduces its operating costs.

[0162] This embodiment can adjust the temperature output by the environmental control system and adjust the heat received by the target indoor space through the convection terminal and the radiation terminal, thereby achieving more accurate adjustment of the indoor temperature of the target indoor space and facilitating the provision of indoor heating comfort.

[0163] In one possible embodiment, the method further includes the following after step S30:

[0164] Step B10: Obtain the temperature of the second refrigerant in the environmental control system;

[0165] Step B20: When the temperature of the second refrigerant meets the third condition, shut down the gas equipment;

[0166] The third condition includes the difference between the second refrigerant temperature and the third target refrigerant temperature of the environmental control system being greater than the fifth preset value and lasting for the second preset duration, or the difference between the second refrigerant temperature and the third target refrigerant temperature being greater than the fifth preset value and lasting for the second preset duration.

[0167] It should be noted that the second refrigerant temperature refers to the current actual outlet water temperature of the environmental control system, which can be obtained by detecting the current outlet water temperature of the environmental control system. The fifth preset value and the second preset duration can both be set based on actual conditions; this embodiment does not impose specific limitations on them.

[0168] When the difference between the second refrigerant temperature and the third target refrigerant temperature is greater than the fifth preset value and continues for the second preset duration, it indicates that the second refrigerant temperature is greater than the third target refrigerant temperature and is relatively stable. At this time, the gas equipment can be shut down to reduce the waste of heating resources, thereby improving the energy efficiency of the environmental control system and reducing the operating cost of the environmental control system.

[0169] For example, the second refrigerant temperature of the environmental control system is obtained. If the difference between the second refrigerant temperature and the third target refrigerant temperature is greater than a fifth preset value and remains so for a second preset duration, the gas equipment is shut off, and the heat is provided by the heat pump system. In other embodiments, the gas equipment is shut off when the difference between the second refrigerant temperature and the third target refrigerant temperature is greater than the fifth preset value.

[0170] In one possible embodiment, the method further includes the following after step S30:

[0171] Step C10: Obtain the spatial temperature of all target indoor spaces in the environmental control system;

[0172] Step C20: Determine the temperature difference between each space temperature and the corresponding set temperature;

[0173] Step C30: When all temperature differences are greater than the fourth preset value, shut down the gas equipment.

[0174] It should be noted that when the temperature difference between all target indoor spaces is greater than the fourth preset value, it indicates that the temperature of the target indoor space is higher than the set temperature. This means that the temperature of each target indoor space exceeds the set temperature, and the gas equipment can be shut off. Even after shutting off the gas equipment, the temperature of the target indoor space will not easily drop below the set temperature quickly because the temperature difference between the target indoor spaces is greater than the fourth preset value. Therefore, the energy efficiency of the environmental control system can be improved and its operating costs reduced without affecting the heating effect of the environmental control system.

[0175] For example, when both the heat pump system and the gas appliance are operating, the ambient temperature and set temperature of each target indoor space in the environmental control system can be obtained, and the difference between the ambient temperature and the set temperature of each target indoor space can be calculated to obtain the temperature difference value of each target indoor space. If all temperature differences are greater than a fourth preset value, the gas appliance can be turned off, and the heat pump system can provide heat. The fourth preset value is obtained from the control unit of the environmental control system. The fourth preset value can be determined based on actual conditions and preset in the control unit. For example, it can be determined through experiments based on the model of the heat control equipment. This embodiment does not specifically limit this.

[0176] In one possible embodiment, the method further includes the following after step S30:

[0177] Step C10: Obtain the outdoor ambient temperature. When the outdoor ambient temperature meets the fourth condition, turn off the gas equipment.

[0178] The fourth condition includes an outdoor ambient temperature greater than a preset temperature threshold for a third preset duration, or an outdoor ambient temperature greater than a preset temperature threshold for a third preset duration.

[0179] It should be noted that if the outdoor ambient temperature exceeds the preset temperature threshold and remains above it for the third preset duration, it indicates that the outdoor ambient temperature is rising but relatively stable, and will not affect the heating capacity of the heat pump system. Therefore, it is not necessary to activate the gas heating equipment for supplemental heating; the heating demand of the environmental control system can be met through the heat pump system alone. This achieves both improved heating performance and reduced operating costs, thus enhancing the energy efficiency of the environmental control system.

[0180] For example, when all gas appliances in the heat pump system are operating, the outdoor ambient temperature is detected. If the outdoor ambient temperature exceeds a preset temperature threshold and remains above it for a third preset duration, the gas appliances are shut off. Heating can then be provided by the heat pump system. In other embodiments, the gas appliances are shut off when the outdoor ambient temperature exceeds the preset temperature threshold.

[0181] In this embodiment, when both the gas equipment and the heat pump system are running, the gas equipment is shut down when the outdoor ambient temperature is greater than a preset temperature threshold and lasts for a third preset duration, when the difference between the second refrigerant temperature and the third target refrigerant temperature is greater than a fifth preset value and lasts for a second preset duration, and / or when the temperature difference of all target indoor spaces is greater than a fourth preset value.

[0182] In one feasible embodiment, both the convection end and the radiation end are located in the refrigerant circulation loop, or the convection end is located in the heat pump system and the radiation end is located in the refrigerant circulation loop.

[0183] In this embodiment, the environmental control system includes a refrigerant circulation loop, and the energy supply system includes a heat pump system. The heat pump system is connected to the refrigerant circulation loop for heat exchange. (Refer to...) Figure 1 and Figure 2 Both the convection and radiation ends can be located in the refrigerant circulation loop; or, refer to... Figure 3 , Figure 3 The heat pump system in the environmental control system shown may also include a refrigerant circulation loop. The convection terminal can be located on the refrigerant circulation loop of the heat pump system, and the radiant terminal can be located on the refrigerant circulation loop, such as... Figure 3 The environmental control system shown can provide heat to the convection terminal through a refrigerant circulation loop.

[0184] To better understand the embodiments of the present invention, please refer to Figure 5The process of this embodiment of the invention is described as follows: The low-temperature heat compensation function of the environmental control system is activated, and the heat pump system is controlled to operate in heating mode. When the outdoor ambient temperature is lower than a preset low-temperature threshold, the indoor temperature is obtained. When the indoor temperature is lower than a second preset value, or the difference between the indoor temperature and the corresponding set temperature is less than a third preset value, the convection terminal and the radiant terminal are turned on. When the indoor temperature is greater than or equal to the second preset value, or the difference between the indoor temperature and the corresponding set temperature is greater than or equal to the third preset value, the radiant terminal is turned on. Whether to turn on the gas heating equipment is determined based on the first refrigerant temperature and the first target refrigerant temperature. When the temperature difference between the first refrigerant temperature and the first target refrigerant temperature is greater than or equal to the first preset value, or the temperature difference is less than or equal to the first preset value and has not lasted for a first preset duration, the gas equipment is not turned on. When the temperature difference between the first refrigerant temperature and the first target refrigerant temperature is greater than the first preset value and lasts for the first preset duration, the gas equipment is turned on to supplement the heat. Based on the temperature difference, the first rated heating capacity and the second rated heating capacity of the heat pump system, the second target refrigerant temperature of the gas equipment is determined, and the operation of the gas equipment is controlled according to the second target refrigerant temperature.
