[0054] 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

[0055] 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.

[0056] The main technical solution of this invention is as follows: An environmental control system includes a gas appliance, a heat pump system, and terminal devices. The terminal devices include at least two types of terminals, and both the gas appliance and the heat pump system are configured to supply energy to the terminal devices. The system controls the activation of the gas appliance and / or the heat pump system based on the outdoor temperature. The system acquires the indoor temperature of the space where the terminal devices are located, determines the target terminal device to be activated based on the indoor temperature, and controls the activation of the target terminal device. The terminal devices include convection terminals and radiant terminals. When the gas appliance or heat pump system is activated, after activating the target terminal device, the refrigerant temperature in the refrigerant circulation loop is detected. Based on this refrigerant temperature, it is determined whether the unactivated target device in the gas appliance and heat pump system needs to be activated for supplementary heating.

[0057] This system automatically activates gas appliances and / or heat pump systems, automatically identifies and activates the target terminals, thus improving the intelligence of the environmental control system. It eliminates the need for manual adjustment by the user and requires no user training on when to activate terminals, gas appliances, or heat pump systems, reducing the learning curve and enhancing the user experience.

[0058] Furthermore, the number of terminals activated and the type of target terminals affect the heat exchange area of ​​the terminal devices when heating the indoor space. Changes in the heat exchange area of ​​the terminal devices also affect the refrigerant temperature in the refrigerant circulation loop. When the heat exchange area increases, the refrigerant temperature may decrease. Therefore, this invention obtains the temperature in the refrigerant circulation loop when the target terminals are activated, allowing for a more accurate determination of the refrigerant temperature currently flowing out of the environmental control system. This is different from using the refrigerant temperature when the gas appliances and / or heat pump system are activated but the terminal devices are not yet activated to determine whether the gas appliances or heat pump system need to be activated for supplemental heating. This embodiment of the invention detects the refrigerant temperature when the target terminals are activated, thereby more accurately determining the refrigerant temperature currently flowing out of the environmental control system. This facilitates timely control of the gas appliances and / or heat pump system based on the refrigerant temperature and ambient temperature, thus improving the heating effect of the environmental control system.

[0059] The environmental control system proposed in this embodiment of the invention includes a gas equipment, a heat pump system, and terminal equipment. The terminal equipment includes at least two types of terminals, and both the gas equipment and the heat pump system are configured to supply energy to the terminal equipment.

[0060] Specifically, the environmental control system in this embodiment of the invention can have various structures, including: the environmental control system includes a gas equipment, a heat pump system, terminal equipment and a refrigerant circulation loop, the convection terminal and the radiant terminal are both connected to the refrigerant circulation loop for heat exchange, the gas equipment and the heat pump system supply energy to the terminal equipment through the refrigerant circulation loop, and the terminal equipment may include a convection terminal and a radiant terminal.

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 the 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.

The terminal equipment may include convection terminals and radiant terminals. The heat pump system includes an outdoor unit, an indoor unit, a hydraulic module, and a refrigerant circulation loop. Both the convection terminals and radiant terminals 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.

[0063] 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 provide heat to terminal devices, which then heat the indoor space where the terminal devices are located.

[0064] 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.).

[0065] In an environmental control system, both the radiant and convective terminals can be located in the refrigerant circulation loop, or the convective terminal can be located in the heat pump system and the radiant terminal can be located in the refrigerant circulation loop.

[0066] 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.

[0067] In this embodiment of the invention, the environmental control system can have various structures; please refer to [reference needed]. Figures 1-3 , respectively Figures 1-3 The environmental control system shown will be explained.

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.

[0071] 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.

[0072] 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 ambient temperature. 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.

[0074] 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. The convection terminal can be a fan coil unit. 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.

The target indoor space is an indoor space with heat exchange requirements. For example, if a user turns on the environmental control system for cooling or heating in a certain indoor space, then that indoor space is the target indoor space. At least one convection terminal and / or at least one radiant terminal are provided in the target indoor space. Figure 1 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 transfers heat to each radiant and convective terminal to provide heat to the 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.

The convection 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 the gas appliance provide energy to the radiant terminals through the refrigerant circulation loop, and the outdoor unit provides heat to the convection terminals through the refrigerant circulation loop.

[0077] 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 terminal equipment 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. The convection terminal 41 provided on the refrigerant circulation loop 120 can be an indoor unit with a duct.

[0078] 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.

[0079] 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.

[0080] Outdoor unit 110 can be a multi-split outdoor unit. Outdoor unit 110 can discharge refrigerant into refrigerant circulation loop 120.

[0081] 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.

[0082] 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.

[0083] Reference Figure 2 ,like Figure 2 Based on the environmental control system shown, the control method of the environmental control system includes: acquiring the outdoor temperature; controlling the gas equipment and / or heat pump system to start based on the outdoor temperature; acquiring the indoor temperature of the target indoor space; determining the target terminal equipment that needs to be turned on based on the indoor temperature, and controlling the target terminal to turn on. For example, Figure 2 The environmental control system shown can output refrigerant from the hydraulic module of the heat pump system to the refrigerant circulation loop when the heat pump system is started and running in heating mode.

[0084] In other embodiments, please refer to Figure 3 The environmental control system shown includes gas equipment, a heat pump system, terminal equipment, and a refrigerant circulation loop. The terminal equipment may include convection terminals and radiant terminals. The heat pump system includes an outdoor unit, an indoor unit, a hydraulic module, and a refrigerant circulation loop. Both the convection terminals and radiant terminals 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.

[0085] 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 includes a radiant terminal 42 and a convection terminal 41.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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 ambient temperature of the indoor space, etc.

For example, Figure 3 The environmental control system shown allows for the output of refrigerant from the hydraulic module of the heat pump system to the refrigerant circulation loop when the heat pump system is started and operating in heating mode. The target indoor space is defined as an indoor space with heat exchange requirements; for example, if a user turns on the environmental control system for cooling or heating in a certain indoor space, that indoor space is considered the target indoor space. At least one convection terminal and / or at least one radiant terminal are installed within the target indoor space. Figure 3 In the environmental control system shown, both the convection terminal and the radiation terminal are connected to the refrigerant circulation loop.

[0094] 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 system shown. The difference is that, Figure 1 The 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.

[0095] In other embodiments, Figures 1-3 The environmental control systems shown can all utilize gas-fired equipment or heat pump systems 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; for 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 or 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.

[0096] Based on this, the present invention proposes a control method for an environmental control system according to the first embodiment, which can... Figures 1-4The environmental control system includes gas appliances, a heat pump system, and terminal equipment. The terminal equipment includes at least two types of terminals. Both the gas appliances and the heat pump system are configured to supply energy to the terminal equipment. The control methods of the environmental control system include:

[0097] Step S10: Obtain the outdoor temperature;

[0098] It should be noted that the terminal equipment includes at least two types of terminals, namely convection terminals and radiant terminals. Radiant terminals can be underfloor heating coils, radiant panels, capillary networks, etc., while convection terminals can be fan coil units, indoor air duct units, etc.

[0099] Outdoor temperature refers to the ambient temperature outside the building. It can be detected by temperature sensors or other temperature-measuring devices located outdoors. The outdoor temperature affects the heating capacity of a heat pump system; in low-temperature environments, the system's heating capacity decreases. At higher temperatures, the heat pump system has higher heating efficiency and better heating capacity. The heating capacity of gas-fired appliances is not affected by outdoor temperature.

[0100] For example, in response to a heating command, the outdoor temperature is acquired. The heating command is used to instruct the environmental control system to start heating. The heating command can be triggered by a user on a terminal, which can be an electronic device such as a mobile terminal, tablet, or computer. This embodiment does not specifically limit this. When the environmental control system responds to the heating command, it can first acquire the outdoor temperature, which facilitates subsequent determination to start the gas equipment and / or heat pump system based on the outdoor temperature.

[0101] Step S20: Control the gas equipment and / or heat pump system to start according to the outdoor temperature;

[0102] It should be noted that since outdoor temperature affects the heating capacity of the heat pump system, the order in which the gas appliance and the heat pump system should be turned on should be determined based on the outdoor temperature. When the outdoor temperature is low, the gas appliance can be turned on first; when the outdoor temperature is high, the heat pump system can be turned on first; when the outdoor temperature is neither high nor low, both the gas appliance and the heat pump system can be turned on simultaneously.

[0103] In a feasible embodiment, step S20 includes steps S21 to S23:

[0104] Step S21: When the outdoor temperature meets the first condition, start the gas equipment;

[0105] It should be noted that the first condition includes an outdoor temperature lower than a first preset value. An outdoor temperature lower than the first preset value indicates a low outdoor temperature, which will cause a decrease in the heating capacity of the heat pump system. However, since the heating capacity of gas appliances does not decrease in low-temperature environments, the gas appliances can be turned on for heating. That is, when the outdoor temperature meets the first condition, the gas appliances will be started first.

[0106] After the gas appliance is started, it can be controlled to operate according to the first target refrigerant temperature of the environmental conditioning system. The first target refrigerant temperature is the target value of the temperature of the refrigerant flowing out of the environmental conditioning system. The first target refrigerant temperature can be determined based on the set temperature of the indoor space where the terminal device is located and the indoor temperature. In other embodiments, the gas appliance can also be controlled to operate according to a pre-set target refrigerant temperature.

[0107] For gas-fired appliances, the temperature of the refrigerant output can be adjusted by regulating the natural gas proportional valve, the number of burner ignitions, and / or the amount of air circulation. This allows for control of the appliance's operation based on a target refrigerant temperature. For example, increasing the opening of the natural gas proportional valve, the number of burner ignitions, and / or the amount of air circulation can increase the appliance's output. Conversely, decreasing the opening of the natural gas proportional valve, the number of burner ignitions, and / or the amount of air circulation can decrease the appliance's output.

[0108] Because the heating capacity of a heat pump system decreases in low-temperature environments, resulting in poor heating performance, this embodiment first turns on the gas equipment for heating to avoid turning on the heat pump system in low-temperature environments and thus avoid increasing the operating costs of the environmental control system.

[0109] Step S22: When the outdoor temperature meets the second condition, start the heat pump system;

[0110] It should be noted that the second condition includes: the outdoor temperature is greater than or equal to the second preset value, and the second preset value is greater than the first preset value.

[0111] When the outdoor temperature is greater than or equal to the second preset value, it indicates a high outdoor temperature and a high heating efficiency for the heat pump system. The higher the heat source temperature, the more heat energy the heat pump system absorbs, thus outputting more heat and improving heating efficiency. Therefore, when the outdoor temperature is greater than or equal to the second preset value, the heat pump system can be activated first, controlling its operation in heating mode. This allows the indoor space to quickly reach the set temperature without turning on gas appliances, ensuring the heating effect of the environmental control system while maintaining low operating costs.

[0112] After the heat pump system is started, its operating mode can be controlled, and its operation can be controlled according to a first target refrigerant temperature. In other embodiments, the heat pump system can also be controlled according to a pre-set target refrigerant temperature.

[0113] Step S23: When the outdoor temperature does not meet the first and second conditions, start the gas equipment and heat pump system;

[0114] It should be noted that when the outdoor temperature does not meet the first and second conditions, it means that the outdoor temperature is greater than or equal to the first preset value and less than the second preset value, indicating that the outdoor temperature is moderate, neither too low nor too high. For example, the first preset value could be -15℃ and the second preset value could be 7℃. When the outdoor temperature is greater than the first preset value and less than the second preset value, the heat pump system and gas appliances can be turned on simultaneously to improve heating efficiency. Heating mode refers to the heat pump system activating its heating function. Activating heating mode increases the temperature of the refrigerant in the refrigerant circulation loop, thus transferring heat to the terminal devices.

[0115] The working principle of a heat pump system is to absorb heat from a low-grade heat source such as air by doing work with a compressor and transfer it to a medium such as water to produce hot water. The higher the temperature of the heat source, the more heat energy the heat pump system absorbs, thus it can output more heat and improve heating efficiency. For example, when the outdoor temperature is higher than the second preset value, the outdoor temperature is higher, so the heating efficiency of the heat pump system will also increase, thus achieving good heating effect with low operating costs.

[0116] When the outdoor temperature is lower than the second preset value but higher than the first preset value, the heating efficiency of the heat pump system cannot reach the heating efficiency of the heat pump system when the outdoor temperature is higher than the second preset value. It is understandable that when the outdoor temperature is moderate, the heat pump system and gas equipment are turned on to achieve a good heating effect with low operating costs.

[0117] For example, when the outdoor temperature is lower than a first preset value, the gas equipment is started and its operation is controlled according to a first target refrigerant temperature. When the outdoor temperature is greater than or equal to a second preset value, the heat pump system is started and its operation is controlled according to the first target refrigerant temperature. The heat pump system is also controlled to operate in heating mode. When the outdoor temperature is greater than the first preset value and less than the second preset value, the gas equipment and the heat pump system are started and their operation is controlled to operate in heating mode. The gas equipment is also controlled to operate according to the first target refrigerant temperature.

[0118] In a feasible embodiment, after step S23, steps S231 to S233 are further included:

[0119] Step S231: Determine the first target refrigerant temperature based on the indoor temperature of the target indoor space and the corresponding set temperature;

[0120] Step S232: Reduce the current first target refrigerant temperature of the environmental control system to obtain the second target refrigerant temperature;

[0121] Step S233: Control the operation of the heat pump system according to the second target refrigerant temperature, and control the operation of the gas equipment according to the first target refrigerant temperature.

[0122] It should be noted that the first target refrigerant temperature refers to the target value of the temperature of the refrigerant flowing out of the environmental control system. The first target refrigerant temperature can change with variations in the indoor temperature and set temperature of the target indoor space. For example, the highest set temperature in each target indoor space can be selected as the first target refrigerant temperature. Adjusting the first target refrigerant temperature involves calculating the difference between the set temperature and the corresponding indoor temperature in each target indoor space. The first target refrigerant temperature can be adjusted based on the largest difference. For instance, when the difference is greater than a preset adjustment threshold, the first target refrigerant temperature can be increased; when the difference is less than the preset adjustment threshold, the first target refrigerant temperature can be decreased. The preset adjustment threshold can be determined based on actual conditions, and this embodiment does not impose specific limitations on it.

[0123] In this embodiment, after both the control gas equipment and the heat pump system are started, the current first target refrigerant temperature of the environmental conditioning system can be obtained, and the current first target refrigerant temperature can be reduced to obtain a second target refrigerant temperature. The first target refrigerant temperature is greater than the second target refrigerant temperature.

[0124] For example, a preset adjustment value can be determined, and this preset adjustment value is used to reduce the current first target refrigerant temperature. The preset adjustment value can be determined based on actual conditions; for example, it can be determined after testing the environmental control system. The second target refrigerant temperature refers to the target value of the refrigerant temperature flowing out of the heat pump system. For example, the difference between the first target refrigerant temperature and the preset adjustment value is calculated to obtain the second target refrigerant temperature. The second target refrigerant temperature is lower than the first target refrigerant temperature.

[0125] After starting the gas equipment, the operation of the gas equipment can be controlled according to the first target refrigerant temperature.

[0126] When the outdoor temperature is greater than or equal to a first preset value but less than a second preset value, the heating efficiency of the heat pump system is lower than when the outdoor temperature is greater than the second preset value. However, the heating capacity of the heat pump system is less affected by the current outdoor temperature, so the heat pump system can be controlled to output a lower refrigerant temperature to improve its energy efficiency and avoid excessive energy waste. Meanwhile, the gas appliance operates at a first target refrigerant temperature, which is greater than the second target refrigerant temperature. Therefore, by combining the heat output of the gas appliance and the heat pump system, the indoor temperature can be quickly increased at low cost, thus improving the user's heating experience.

[0127] In other embodiments, the gas equipment can be controlled to operate according to a first preset refrigerant temperature, or the heat pump system can be controlled to operate according to a second preset refrigerant temperature, wherein the second preset refrigerant temperature is lower than the first preset refrigerant temperature.

[0128] For example, a first target refrigerant temperature of the environmental control system is obtained, the difference between the first target refrigerant temperature and a preset adjustment value is calculated to obtain a second target refrigerant temperature, and the operation of the heat pump system is controlled according to the second target refrigerant temperature. The operation of the gas equipment is controlled according to the first target refrigerant temperature.

[0129] In a feasible embodiment, after step S233, the method further includes: steps A10 to A30:

[0130] Step A10: Obtain the indoor temperature of all target indoor spaces in the environmental control system;

[0131] Step A20: Determine the temperature difference between each indoor temperature and the corresponding set temperature;

[0132] Step A30: When all temperature differences are greater than the first preset temperature difference, shut down the gas equipment.

[0133] It should be noted that environmental control equipment can have multiple terminal devices, which can be distributed in different indoor spaces. The set temperatures for each indoor space can be the same or different. The temperature difference is the difference between the indoor temperature and the corresponding set temperature. The indoor space where heat exchange is required is the target indoor space.

[0134] When the temperature difference between all target indoor spaces is greater than the first preset temperature difference, it indicates that the current heating capacity of the target indoor spaces is sufficient, so the gas equipment can be turned off. Even if the gas equipment is turned off, the indoor temperature of the target indoor spaces will not easily drop below the set temperature, thus improving the energy efficiency of the environmental control system and reducing its operating costs without affecting the heating effect of the environmental control system.

[0135] For example, when the heat pump system is controlled to operate according to the second target refrigerant temperature and the gas equipment is controlled to operate according to the first target refrigerant temperature, the indoor temperature of all target indoor spaces in the environmental control system is obtained, the temperature difference between each indoor temperature and the corresponding set temperature is calculated, and the gas equipment is turned off when all temperature differences are greater than the first preset temperature difference.

[0136] In one possible embodiment, step A31 is further included after step A30:

[0137] Step A31: Determine the third target refrigerant temperature based on the indoor temperature of the target indoor space and the corresponding set temperature, and control the operation of the heat pump system based on the third target refrigerant temperature.

[0138] It's important to note that when both the gas appliance and the heat pump system are running simultaneously, the heat pump system's operation is controlled based on the second target refrigerant temperature. Therefore, in this situation, if the gas appliance is turned off, the refrigerant temperature output by the ambient temperature control system will not include the temperature output by the gas appliance. If the refrigerant temperature output by the heat pump system is not increased, the refrigerant temperature output by the ambient temperature control system will decrease, potentially affecting heating efficiency. Alternatively, the target indoor space may already be at the set temperature, requiring less heat. In this case, not adjusting the refrigerant temperature output by the heat pump system may also negatively impact heating efficiency. Therefore, after turning off the gas appliance, it is necessary to adjust the refrigerant temperature output by the heat pump system.

[0139] The third target refrigerant temperature refers to the target temperature of the refrigerant flowing out of the heat pump system when the gas equipment is turned off, assuming both the gas equipment and the heat pump system are started simultaneously.

[0140] For example, the highest set temperature in each indoor space is selected as the initial target refrigerant temperature. This initial target refrigerant temperature is then adjusted. For instance, the difference between the set temperature and the corresponding indoor temperature in each target indoor space can be calculated. Based on the largest difference, the initial target refrigerant temperature is adjusted to obtain a third target refrigerant temperature. For example, when the difference is greater than a preset adjustment threshold, the initial target refrigerant temperature can be increased; when the difference is less than the preset adjustment threshold, the initial target refrigerant temperature is decreased. The preset adjustment threshold can be determined based on actual conditions, and this embodiment does not specifically limit it. Controlling the operation of the heat pump system according to the third target refrigerant temperature facilitates ensuring the heating effect of the environmental control system.

[0141] Step S30: Obtain the indoor temperature of the target indoor space;

[0142] It should be noted that indoor temperature refers to the current temperature of the target indoor space. The target indoor space also has a set temperature, which is the desired temperature to be achieved. The indoor temperature can be detected by a temperature sensor installed in the target indoor space. The environmental control system may include multiple terminal devices, which can be distributed across different indoor spaces. The target indoor space is the indoor space with heat exchange requirements.

[0143] Step S40: Determine the target terminal to be turned on among the terminal devices based on the indoor temperature, and control the target terminal to turn on.

[0144] It should be noted that the target terminal refers to the terminal in the target indoor space that needs to be turned on. The target terminal can be a convection terminal and / or a radiant terminal. The target terminal to be turned on can be selected based on the indoor temperature. After the target terminal is turned on, it can supply heat to the corresponding target indoor space. Each target indoor space can select the target terminal to be turned on in the terminal equipment. Different target indoor spaces can have different or the same target terminal turned on.

[0145] 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 terminals and convection terminals can be equipped with automatically controlled valves. For instance, for any target indoor space, it can be determined whether the radiant terminals and / or convection terminals in the target indoor space need to be turned on based on the indoor temperature of the target indoor space.

[0146] In a possible embodiment, step S40 further includes steps S41 and / or S42:

[0147] Step S41: When the indoor temperature meets the third condition, determine that the target terminal includes both convection terminal and radiation terminal, and control the convection terminal and radiation terminal to open.

[0148] It should be noted that the third condition includes the difference between the indoor temperature and the set temperature of the target indoor space being less than the second preset temperature difference. In other embodiments, the first condition may also include the indoor temperature being less than a preset temperature value, or the difference between the indoor temperature and the corresponding set temperature being less than the second preset temperature difference.

[0149] The second preset temperature difference is the highest temperature difference threshold required for heating the target indoor space. The difference between the indoor temperature and the set temperature can be negative, positive, or 0. The second preset temperature difference, the preset temperature value, and the set temperature can all be set based on actual conditions.

[0150] In one feasible embodiment, the terminal device includes a convective terminal and a radiative terminal, and the refrigerant circulation loop is connected to the heat pump system and the gas equipment for heat exchange respectively. Both the convective terminal and the radiative terminal are located in the refrigerant circulation loop, or the convective terminal is located in the heat pump system and the radiative terminal is located in the refrigerant circulation loop.

[0151] It should be noted that the radiant terminal is located on the refrigerant circulation loop. The convective terminal can be located on the refrigerant circulation loop, or it can be located on the refrigerant circulation loop of the heat pump system. (See reference...) Figure 1 The environmental control system shown has both radiant and convective terminals located on the refrigerant circulation loop. The convective terminals located on the refrigerant circulation loop can be fan coil units. The radiant terminals can be radiant panels, etc.

[0152] Reference Figure 2 The environmental control system shown has radiant terminals located on the refrigerant circulation loop and convective terminals located on the refrigerant circulation loop of the heat pump system. The convective terminals located on the refrigerant circulation loop can be indoor units with ductwork. The radiant terminals can be radiant panels, etc.

[0153] Reference Figure 3 The environmental control system shown has both radiant and convective terminals located on the refrigerant circulation loop. The convective terminals located on the refrigerant circulation loop can be fan coil units. The radiant terminals can be underfloor heating systems, etc.

[0154] like Figure 1 , Figure 2 and Figure 3 The environmental control systems shown can all activate the convection and radiant terminals when the indoor temperature meets the third condition. In other embodiments, such as Figure 2 The environmental control system shown can be activated by turning on the radiant terminal first, even when only the gas appliances are running, and the indoor temperature meets the third condition, because... Figure 2 In the environmental control system shown, if the heat pump system is not turned on, the convection terminal on the refrigerant circulation loop of the heat pump system will not receive energy, so the convection terminal may not be turned on. After the radiant terminal is turned on, when the refrigerant temperature is detected to meet the preset heat replenishment conditions to start the unturned heat pump system, the indoor temperature is then obtained. If the indoor temperature meets the third condition, the convection terminal is turned on. If the indoor temperature does not meet the third condition, the convection terminal is not turned on.

[0155] Step S42: When the indoor temperature does not meet the third condition, determine that the target terminal is a radiant terminal and control the radiant terminal to turn on;

[0156] The third condition includes: the difference between the indoor temperature and the set temperature of the target indoor space is less than the second preset temperature difference.

[0157] It should be noted that when the indoor temperature does not meet the third 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 heating amount in the target indoor space and thus reducing the heat.

[0158] For example, when the difference between the indoor temperature and the set temperature is less than a second preset temperature difference, the convection terminal and the radiant terminal are controlled to open; when the indoor temperature is greater than or equal to the second preset temperature difference, the radiant terminal is controlled to open and the convection terminal is controlled to close. In other embodiments, when the indoor temperature is greater than or equal to the second preset temperature difference and less than a preset temperature difference threshold, the radiant terminal is controlled to open and the radiant terminal is controlled to close. A difference between the indoor temperature and the set temperature greater than or equal to the second preset temperature difference but less than the preset temperature difference indicates that there is still a difference between the indoor temperature and the set temperature, or that the target indoor space still needs heating to maintain its indoor temperature.

[0159] When the difference between the room temperature and the set temperature is small, only radiant heating is turned on to ensure heating comfort.

[0160] In a feasible embodiment, after step S41, steps S411 to S412 are further included:

[0161] Step S411: Obtain the current indoor temperature of the target indoor space;

[0162] Step S412: When the difference between the indoor temperature and the corresponding set temperature is greater than the first preset temperature difference, the convection terminal is turned off.

[0163] 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 is greater than the first preset temperature difference, it indicates that the target indoor space may not require heating from multiple terminals. In this case, the convection terminals can be turned off, and the target indoor space can be heated through the radiant heating terminals. The convection terminals can be ducted indoor units or fan coil units.

[0164] For example, for any terminal device in the environmental control system located in the target indoor space, if the difference between the space temperature of the target indoor space and the corresponding set temperature is greater than a third 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 indoor space temperature is high, and even if only the radiant terminal is turned on, it will not affect the heating effect of the target indoor space.

[0165] For further details, please refer to Figure 5 In one feasible embodiment, the environmental control system further includes a refrigerant circulation loop, which is connected to the heat pump system and the gas equipment for heat exchange. After the step of controlling the target terminal to turn on, the system further includes steps B10 to B20:

[0166] Step B10: With the heat pump system or gas equipment in the on state, detect the refrigerant temperature in the refrigerant circulation loop;

[0167] Step B20: When the refrigerant temperature meets the preset heat replenishment conditions, control the gas equipment and the target equipment in the heat pump system that has not been turned on to turn on.

[0168] The preset heat compensation conditions include that the difference between the refrigerant temperature and the first target refrigerant temperature is less than the preset heat compensation difference value.

[0169] It should be noted that the refrigerant temperature in the refrigerant circulation loop is detected when the heat pump system or gas equipment is on, and when the target terminal is on. The refrigerant temperature can be detected after a preset time since the target terminal was turned on, or it can be detected immediately upon the target terminal being turned on. The preset time can be determined based on actual conditions, and this embodiment does not limit this.

[0170] The preset supplemental heating condition indicates that the heating equipment that is prioritized for activation is providing insufficient heat. The target equipment refers to the heating equipment that was not prioritized for activation. The target equipment can be either gas-fired equipment or a heat pump system. When the outdoor temperature meets the first condition, the heating equipment that is prioritized for activation is the gas-fired equipment; when the outdoor temperature meets the second condition, the heating equipment that is prioritized for activation is the heat pump system.

[0171] When the heating equipment to be activated first is a heat pump system or a gas appliance, and the target terminal is activated, the refrigerant temperature can be obtained after a preset time. In other embodiments, the preset time may include a first preset time and a second preset time. When the heating equipment to be activated first is a heat pump system, the refrigerant temperature can be obtained after the first preset time since the target terminal was activated; when the heating equipment to be activated first is a gas appliance, the refrigerant temperature can be obtained after the second preset time since the target terminal was activated. The first preset time and the second preset time may be the same or different.

[0172] If the priority heating device is a heat pump system, the target device is a gas appliance.

[0173] The preset heat compensation conditions include that the difference between the refrigerant temperature and the first target refrigerant temperature is less than a preset heat compensation difference value. The preset heat compensation difference value can be divided into a first preset heat compensation difference value and a second preset heat compensation difference value. Specifically, the preset heat compensation conditions can also include: when the priority start-up equipment is a heat pump system, the refrigerant temperature difference is less than the first preset heat compensation difference value; and when the priority start-up equipment is a gas equipment, the refrigerant temperature difference is less than the second preset heat compensation difference value.

[0174] Because heat pump systems and gas appliances have different heating capacities, different threshold values ​​can be set to trigger the activation of the target appliance when determining whether it needs to be turned on, depending on which heating appliance is prioritized for activation. For example, when the heating appliance is prioritized for activation, the threshold value can be set to a first preset heat compensation difference. If the target terminal is activated and the refrigerant temperature difference is less than the first preset heat compensation difference, then the gas appliance is activated. If the priority heating appliance is a gas appliance, the threshold value can be set to a second preset heat compensation difference. If the target terminal is activated and the refrigerant temperature difference is less than the second preset heat compensation difference, then the heat pump system is activated. This allows for more accurate activation of the target appliance, thereby reducing the operating costs of the environmental control system while ensuring heating efficiency.

[0175] For example, when the gas appliance or heat pump system is in the on state and the target terminal is on, when the difference between the refrigerant temperature and the first target refrigerant temperature is detected to be less than a preset heat compensation difference value, the un-turned target device in the gas appliance and heat pump system is identified and the target device is turned on.

[0176] The first preset heat compensation difference, the second preset heat compensation difference, the preset second duration, and the preset first duration can be determined based on actual conditions. For example, they can be determined by testing the environmental control system.

[0177] For example, when the heat pump system is on, the gas equipment is not on, and the target terminal is on, the refrigerant temperature is detected. When the refrigerant temperature meets the preset heat replenishment conditions, the un-turned target equipment is determined to be the gas equipment, and the gas equipment is controlled to turn on.

[0178] When the gas equipment is on but the heat pump system is off, and the target terminal is on, the refrigerant temperature is detected. When the refrigerant temperature meets the preset heat replenishment conditions, the off-target equipment is identified as the heat pump system, and the heat pump system is controlled to start.

[0179] The number of terminals activated and the type of target terminals affect the heat exchange area of ​​the terminal devices when heating the indoor space. Changes in the heat exchange area of ​​the terminal devices also affect the refrigerant temperature in the refrigerant circulation loop. When the heat exchange area increases, the refrigerant temperature may decrease. Therefore, this invention obtains the temperature in the refrigerant circulation loop when the target terminals are activated, allowing for a more accurate determination of the refrigerant temperature currently flowing out of the environmental control system. This is different from using the refrigerant temperature when the gas appliances and / or heat pump system are activated but the terminal devices are not yet activated to determine whether the gas appliances or heat pump system need to be activated for supplemental heating. This embodiment of the invention detects the refrigerant temperature when the target terminals are activated, thereby more accurately determining the refrigerant temperature currently flowing out of the environmental control system. This facilitates timely control of the gas appliances and / or heat pump system based on the refrigerant temperature and ambient temperature, thus improving the heating effect of the environmental control system.

[0180] In a feasible embodiment, after step B20, the method further includes steps B21 to B22:

[0181] Step B21: Obtain the system refrigerant temperature of the environmental control system;

[0182] Step B22: When the system refrigerant temperature meets the fourth condition, shut down the target device;

[0183] The fourth condition includes: the difference between the system refrigerant temperature and the first target refrigerant temperature of the environmental control system is greater than the third preset temperature difference.

[0184] It should be noted that the system refrigerant temperature refers to the refrigerant temperature detected in the refrigerant circulation loop when both the heat pump system and the gas equipment in the environmental control system are running.

[0185] When the priority heating device is a gas-fired appliance, the heat pump system is shut down if the difference between the system refrigerant temperature and the first target refrigerant temperature exceeds the third preset temperature difference.

[0186] In other embodiments, the fourth condition may also include, when the heating device to be turned on first is a heat pump system, the difference between the system refrigerant temperature and the first target refrigerant temperature is greater than a third preset temperature difference; and when the heating device to be turned on first is a gas appliance, the difference between the system refrigerant temperature and the first target refrigerant temperature is greater than a fourth preset temperature difference.

[0187] Because heat pump systems and gas appliances have different heating capacities, different temperature difference thresholds can be set to trigger the shutdown of different target devices when determining whether to shut them down. For example, when the priority heating device is the heat pump system, the temperature difference threshold is set to a third preset temperature difference; that is, when the system refrigerant temperature exceeds the third preset temperature difference, the gas appliance is shut down. When the priority device is the gas appliance, the temperature difference threshold can be set to a fourth preset temperature difference; that is, when the system refrigerant temperature exceeds the fourth preset temperature difference, the heat pump system is shut down. This allows for more accurate shutdown of target devices, thereby reducing the operating costs of the environmental control system while ensuring heating efficiency.

[0188] The first, second, third, and fourth preset temperature differences can be determined based on actual conditions, for example, by conducting experiments on the environmental control system.

[0189] Among them, such as Figure 1 The environmental control system shown is in Figure 1 Both the intermediate refrigerant temperature and the system refrigerant temperature can be obtained by detecting the temperature of the refrigerant in the pipes between the heat exchanger 30 and the terminal equipment; for example Figure 2 The environmental control system shown can be configured such that the refrigerant temperature and the system refrigerant temperature can both be obtained by detecting the refrigerant temperature in the pipe between the hydraulic module 400 and the terminal device 40. For example... Figure 3 In the environmental control system shown, the refrigerant temperature and the system refrigerant temperature can both be obtained by detecting the temperature of the refrigerant in the pipe between the fluid control module 23 and the terminal device 40.

[0190] The difference between refrigerant temperature and system refrigerant temperature is that refrigerant temperature is the refrigerant temperature detected when the heating equipment currently operating in the environmental control system is a heat pump system or a gas equipment, while system refrigerant temperature is the refrigerant temperature detected when the heating equipment currently operating in the environmental control system is a heat pump system and a gas equipment.

[0191] The first target refrigerant temperature is the target value of the refrigerant temperature flowing out of the environmental control system. The second target refrigerant temperature is the target value of the refrigerant temperature flowing out of the heat pump system when both the heat pump system and the gas appliance are running simultaneously, and both are in heating mode. The third target refrigerant temperature is the target value of the refrigerant temperature flowing out of the heat pump system after the gas appliance is turned off, when both the gas appliance and the heat pump system are running simultaneously. For example, ... Figure 1The 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 second target refrigerant temperature, and can also detect whether the refrigerant temperature output by the heat pump system reaches the third target refrigerant temperature. Since the operation of the gas equipment is controlled according to the first target refrigerant temperature in this embodiment of the invention, the refrigerant temperature in the pipe between the gas equipment 300 and the heat exchange device 30 can be detected to detect whether the refrigerant temperature output by the gas equipment reaches the first target refrigerant temperature; the temperature of the pipe between the heat exchange device 30 and the terminal equipment can be detected to detect whether the refrigerant temperature output by the environmental control system reaches the first target refrigerant temperature.

[0192] For example, such as Figure 2 The environmental control system shown can detect the refrigerant temperature in the pipeline between the hydraulic module 400 and the terminal device 40 to determine whether the temperature output by the heat pump system reaches the second target refrigerant temperature. It can also detect the refrigerant temperature in the pipeline between the gas appliance 300 and the heat exchange device to determine whether the refrigerant temperature output by the gas appliance reaches the first target refrigerant temperature. Furthermore, it can detect the refrigerant temperature in the pipeline between the heat exchange device 30 and the terminal device 40 to determine whether the refrigerant temperature output by the environmental control system reaches the first target refrigerant temperature.

[0193] For example, such as Figure 3 The 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 second target refrigerant temperature, and can also detect whether the refrigerant temperature output by the heat pump system reaches the third target refrigerant temperature. Since the operation of the gas equipment is controlled based on the first target refrigerant temperature in this embodiment of the invention, the refrigerant temperature in the pipe between the fluid control module 23 and the terminal device 40 can be detected to determine whether the refrigerant temperature output by the environmental control system reaches the first target refrigerant temperature; the refrigerant temperature in the pipe between the gas equipment 300 and the heat exchange device can also be detected to determine whether the refrigerant temperature output by the gas equipment reaches the first target refrigerant temperature.

[0194] To better understand the embodiments of the present invention, please refer to Figure 6 The process of one embodiment will be described as follows:

[0195] The environmental control system activates the heating function, acquires the outdoor temperature, and determines whether the outdoor temperature is lower than a first preset value. When the outdoor temperature is lower than the first preset value, the gas heating equipment is activated first, and then the indoor temperature of the target indoor space is acquired. If the difference between the indoor temperature and the set temperature is less than a second preset temperature difference, the convection and radiant heating terminals are activated. If the difference between the indoor temperature and the set temperature is greater than or equal to the second preset temperature, the radiant heating terminal is activated. After a preset running time, when the difference between the refrigerant temperature and the first target refrigerant temperature is less than a second preset heat compensation difference, the heat pump system automatically activates for heating.

[0196] When the outdoor temperature is greater than or equal to the second preset value, the heat pump system is activated first for heating, and then the indoor temperature is obtained. When the difference between the indoor temperature and the set temperature is less than the second preset temperature difference, the convection and radiant terminals are activated. If the difference between the indoor temperature and the set temperature is greater than or equal to the second preset temperature, the radiant terminal is activated. After a preset running time, when the difference between the refrigerant temperature and the first target refrigerant temperature is less than the second preset heat compensation difference, the gas heating equipment is automatically activated.

[0197] When the outdoor temperature is greater than or equal to the first preset value and less than the second preset value, the heat pump system and gas equipment are turned on to provide heating. The indoor temperature is then obtained. When the difference between the indoor temperature and the set temperature is less than the second preset temperature difference, the convection terminal and the radiant terminal are turned on. If the difference between the indoor temperature and the set temperature is greater than or equal to the second preset temperature, the radiant terminal is turned on.
