[0049] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0050] The main solution of this application embodiment is: a control method based on an environmental control system, the environmental control system including a heat pump system and a heating system, the heat pump system including an indoor unit, the heating system including terminal devices, the indoor unit and the terminal devices being located in an indoor space, the method including: controlling the operation of the heat pump system to put the indoor unit in a heating state, obtaining the temperature state of the indoor space; and adjusting the heating state of the terminal devices according to the temperature state.

[0051] In this embodiment, for ease of description, the environmental control system will be used as the implementing entity for the following description.

[0052] In existing technologies, when heating systems and heat pump systems are set up simultaneously to regulate indoor temperature, the heating system and heat pump system generally operate independently and according to the parameters configured by the user. This can lead to incoordination between the systems, with excessive heat supply causing energy consumption and insufficient heat supply affecting the heating effect. As a result, there is a problem that energy saving and heating effect cannot be balanced.

[0053] This application provides the above-mentioned solution, in which the two systems no longer operate independently during the indoor heating process, but can cooperate with each other to adapt to the indoor temperature. During the indoor unit's heating process, the heat output of the terminal equipment will not be too large or too small, thereby improving the balance between indoor heating effect and reducing system energy consumption.

[0054] This application proposes an environmental control system.

[0055] In this embodiment, refer to Figure 1 The environmental control system includes a heat pump system 1 and a heating system 2. The heat pump system 1 and the heating system 2 are communicatively connected, but there are no other connections between them besides the communicative connection. The heat pump system 1 includes an indoor unit 11, and the heating system 2 includes terminal equipment 21. Both the indoor unit 11 and the terminal equipment 21 are located in the indoor space.

[0056] In this embodiment, the heat pump system 1 includes at least two indoor units 11, and the heating system 2 includes at least two terminal devices 21. The at least two indoor units 11 and at least two terminal devices 21 are located in at least two indoor spaces. Each indoor space is equipped with at least one indoor unit 11 and at least one terminal device 21. Each indoor space regulates indoor air through the indoor unit 11 and the terminal device 21 therein. In other embodiments, the heat pump system 1 may also include one indoor unit 11, and the heating system 2 may also include one terminal device 21.

[0057] The indoor unit 11 includes an indoor heat exchanger and an indoor fan. Driven by the indoor fan, indoor air can exchange heat with the indoor heat exchanger.

[0058] The heat pump system 1 includes a compressor, an indoor heat exchanger, a throttling device, and an outdoor heat exchanger, which are connected in sequence. The compressor, the throttling device, and the outdoor heat exchanger are all located in the outdoor unit 12 of the heat pump system 1.

[0059] In one implementation, the compressor's exhaust port, indoor heat exchanger, throttling device, and outdoor heat exchanger are connected in sequence. When the compressor is turned on, the refrigerant flows through the indoor heat exchanger, throttling device, and outdoor heat exchanger in sequence and then flows back to the compressor. The indoor heat exchanger is in a heat release state, and the outdoor heat exchanger is in a heat absorption state.

[0060] In another implementation, the heat pump system 1 further includes a reversing assembly (e.g., a four-way valve), with the compressor's exhaust port, return port, indoor heat exchanger, and outdoor heat exchanger all connected to the reversing assembly. The reversing assembly has a first operating state and a second operating state. When the reversing assembly operates in the first operating state, the compressor's exhaust port is connected to the indoor heat exchanger, and the compressor's return port is connected to the outdoor heat exchanger. When the compressor is turned on, the refrigerant flows sequentially through the indoor heat exchanger, the throttling device, and the outdoor heat exchanger before returning to the compressor. The indoor heat exchanger is in a heat-releasing state, and the outdoor heat exchanger is in a heat-absorbing state. When the reversing assembly operates in the second operating state, the compressor's exhaust port is connected to the outdoor heat exchanger, and the compressor's return port is connected to the indoor heat exchanger. When the compressor is turned on, the refrigerant flows sequentially through the outdoor heat exchanger, the throttling device, and the indoor heat exchanger before returning to the compressor. The indoor heat exchanger is in a heat-absorbing state, and the outdoor heat exchanger is in a heat-releasing state.

[0061] In the heating system 2, the terminal equipment 21 includes radiant terminals and / or convection terminals. Radiant terminals may include radiators, underfloor heating, etc., while convection terminals may include fan coil units, etc. The types of terminal equipment 21 in different indoor spaces may be the same or different, and one or more types of terminal equipment 21 may be included in the same indoor space.

[0062] When the heating system 2 is running, the terminal device 21 releases heat to its space. When the heat pump system 1 is running in heating mode, the indoor unit 11 can release heat to its space. When the heat pump system 1 also includes a commutation component, the commutation component operates in a first operating state when the heat pump system 1 is running in heating mode.

[0063] In this embodiment, the heating system 2 also includes a refrigerant circulation loop 22 and a heating device 23, with the heating device 23 and the terminal device 21 both located in the refrigerant circulation loop 22.

[0064] In this embodiment, the heating device 23 is a gas-fired device (such as a gas-fired wall-hung boiler), which heats the flowing refrigerant by burning gas. In other embodiments, the heating device 23 may also be other types of heat-releasing devices, such as a boiler.

[0065] The refrigerant circulation loop 22 is filled with refrigerant, which can flow within it. 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 an organic compound such as ethylene glycol or glycerol, etc.

[0066] The refrigerant in the refrigerant circulation loop 22 can absorb heat in the heating device 23 and then flow to the terminal device 21 to be released into the indoor space. The refrigerant after heat exchange in the terminal device 21 can flow back into the heating device 23 to absorb heat, and so on.

[0067] The refrigerant circulation loop 22 can be equipped with a circulation pump, which can drive the refrigerant to circulate in the refrigerant circulation loop 22 when the circulation pump is turned on.

[0068] The refrigerant circulation loop 22 can be equipped with control valves corresponding to the terminal devices 21. When there is more than one terminal device 21, more than one control valve can be provided, with each control valve corresponding to one terminal device 21. The control valves can regulate the flow of refrigerant in the corresponding terminal device 21. In one implementation, the refrigerant circulation loop 22 can be equipped with a manifold, and the control valve is a distribution valve within the manifold.

[0069] In other embodiments, the heating device 23 may also be a heat pump device, which supplies heat to the terminal device 21.

[0070] In one embodiment, reference is made to Figure 1 Each indoor space regulated by the environmental control system may be equipped with a wired controller 300. The heat pump system 1 may include an outdoor unit 12. The aforementioned first heat exchanger, outdoor heat exchanger, and compressor may be located on the outdoor unit 12. The outdoor unit 12, the circulation pump, the heating device 23, the fluid regulation module (e.g., a manifold), and the wired controller 300 may be connected via signal lines. The wired controller 300 in each indoor space is correspondingly bound to the terminal device 21 in that space and the sub-regulation module connected to the terminal device 21. The wired controller 300 may control at least one of the following: the liquid supply temperature of the sub-regulation module, the circulation pump, the heating device 23, the fluid regulation module, the ambient temperature of the indoor space, etc.

[0071] The environmental control system also includes an environmental detection module 3, which includes an indoor sensor and / or an outdoor sensor. The indoor sensor is used to detect indoor air parameters (e.g., indoor temperature, indoor humidity, indoor enthalpy, etc. at least one), and the outdoor sensor is used to detect outdoor air parameters (e.g., outdoor temperature, outdoor humidity, outdoor enthalpy, etc. at least one).

[0072] The environmental control system also includes a temperature detection module 4, which is located in the refrigerant circulation loop 22 to detect the refrigerant temperature. In this embodiment, the temperature detection module 4 includes a first temperature sensor located on the liquid inlet side of the heating module and a second temperature sensor located on the liquid outlet side of the heating module to detect the refrigerant temperature at the corresponding locations.

[0073] The environmental control system also includes a control device 100. The aforementioned heat pump system 1, heating system 2, environmental monitoring module 03, and temperature monitoring module 04 are all connected to the control device 100. The control device 100 can be located in the heat pump system 1 or in the heating system 2. Alternatively, the control device 100 can be set up independently of the heat pump system 1 and the heating system 2, with both the heat pump system 1 and the heating system 2 communicating with the control device 100.

[0074] The control device 100 includes: at least one processor 1001; and a memory 1002 communicatively connected to the at least one processor 1001, and a timer 1003, etc.; wherein the memory 1002 stores instructions that can be executed by the at least one processor 1001, the instructions being executed by the at least one processor 1001 to enable the at least one processor 1001 to execute the control method of the environmental regulation system in the following embodiment.

[0078] The environmental control system provided in this application, employing the control method of the environmental control system in the following embodiments, can solve the technical problem of how to improve indoor heating efficiency. Compared with the prior art, the beneficial effects of the environmental control system provided in this application are the same as the beneficial effects of the control method of the environmental control system provided in the following embodiments, and other technical features of this environmental control system are the same as those disclosed in the method of the following embodiments, and will not be repeated here.

[0079] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or environmental control system capable of performing the above functions. The following description uses an environmental control system as an example to illustrate this embodiment and the subsequent embodiments.

[0080] Based on this, embodiments of this application provide a control method for an environmental control system, referring to... Figure 3 , Figure 3 This is a flowchart illustrating the first embodiment of the control method for the environmental control system of this application.

[0081] In this embodiment, the environmental control system includes a heat pump system and a heating system. The heat pump system includes an indoor unit, and the heating system includes terminal devices. Both the indoor unit and the terminal devices are located in the indoor space. The control method of the environmental control system includes steps S10 to S20:

[0082] Step S10: Control the heat pump system to operate so that the indoor unit is in heating mode, and obtain the temperature status of the indoor space;

[0083] In this embodiment, the heat pump system includes an outdoor unit and at least two indoor units. The outdoor unit operates in heating mode, while the indoor units in the indoor space are turned on, and the indoor heat exchangers in the indoor units release heat to the space in which they are located.

[0084] The temperature here refers to the temperature in the indoor space where the indoor unit is located when it is in heating mode.

[0085] Temperature status may include at least one of the following: indoor temperature, indoor temperature change rate, whether the indoor temperature has reached the set temperature, the duration during which the indoor temperature has reached the set temperature, the duration during which the indoor temperature has not reached the set temperature, etc.

[0086] When the indoor unit is in heating mode, the temperature of the indoor space can be obtained at preset intervals or when the heat pump system reaches certain operating conditions.

[0087] During the operation of a heat pump system, the terminal equipment can be in heating mode or in a non-heating mode.

[0088] Step S20: Adjust the heating state of the terminal device according to the temperature state.

[0089] In this embodiment, the terminal device includes a radiant terminal, such as a radiator or underfloor heating. It should be noted that the indoor temperature rise rate when the indoor unit is in heating mode is greater than the indoor temperature rise rate when the radiant terminal is in heating mode, and the indoor temperature rise rate when the radiator is in heating mode is greater than the indoor temperature rise rate when the underfloor heating is in heating mode.

[0090] Adjust the heating status of the terminal equipment in at least one of the following ways: start the heating state of the terminal equipment, stop the heating state of the terminal equipment, adjust the refrigerant temperature in the refrigerant circuit of the heating system, adjust the refrigerant flow rate of the terminal equipment, adjust the operating parameters of the heating equipment in the heating system, etc.

[0091] When the terminal device is in a stopped heating state, the decision to start heating can be determined based on the temperature. When the terminal device is in a heating state, the decision to stop heating can be determined based on the temperature, or the heating capacity of the terminal device can be increased or decreased based on the temperature.

[0092] After step S20, the process can return to the step of obtaining the temperature status of the indoor space after a preset time interval.

[0093] This embodiment provides a control method for an environmental regulation system. When a heat pump system and a heating system are set up simultaneously to regulate the indoor temperature, the heating state of the terminal equipment is adjusted based on the indoor temperature state when the indoor unit of the heat pump system is in heating mode. The two systems no longer operate independently during the indoor heating process, but can cooperate with each other to adapt to the indoor temperature state. During the indoor unit's heating process, the heat output of the terminal equipment will not be too large or too small, thereby improving the balance between indoor heating effect and reducing system energy consumption.

[0094] In one feasible implementation, step S20 may include: if the temperature state includes a reached temperature state, controlling the heating system to stop the terminal device from heating or maintain the stopped heating state, or controlling the heating system to adjust the heating capacity of the terminal device according to the actual indoor temperature of the indoor space; and / or, if the temperature state includes a not reached temperature state, adjusting the heating state of the terminal device according to the duration of the not reached temperature state.

[0095] The state of temperature reached or not reached can be determined based on the relationship between the monitored indoor temperature and the set temperature, or it can be determined based on user-input commands. In this embodiment, when the indoor temperature is greater than or equal to the set temperature, the temperature state includes the state of temperature reached; when the indoor temperature is less than the set temperature, the temperature state includes the state of temperature not reached. The heat pump system includes at least two indoor units and at least two terminal devices. The indoor units and terminal devices are associated one-to-one. The associated indoor units and terminal devices are located in the same indoor space. When different indoor units are located in different indoor spaces, the indoor temperature of all indoor spaces is greater than or equal to the corresponding set temperature, and the temperature state includes the state of temperature reached; if the indoor temperature of at least one indoor space is less than the corresponding set temperature, the temperature state includes the state of temperature not reached.

[0096] Temperature status includes conditions where the desired temperature has been reached. In one implementation, the indoor unit maintains heating while the terminal equipment stops heating, and its heating capacity can be adjusted according to the indoor temperature. In another implementation, both the terminal equipment and the indoor unit can maintain heating, and the heating capacity of the terminal equipment is adjusted according to the actual indoor temperature; different actual indoor temperatures correspond to different heating capacities for the terminal equipment. For example, the heating capacity of the terminal equipment can be adjusted based on the relationship between the actual indoor temperature and the target indoor temperature. Alternatively, the heating capacity of the terminal equipment can be adjusted based on the temperature range within which the actual indoor temperature falls. Another example is calculating the heating system's operating parameters by substituting the actual indoor temperature into a formula to adjust the heating capacity of the terminal equipment.

[0097] The duration of the temperature not reached state begins from the moment the indoor unit starts heating or the indoor space changes from a temperature reached state to a temperature not reached state. The timer accumulates continuously while the temperature is in the temperature not reached state.

[0098] The temperature status includes the state before reaching the desired temperature, and different durations correspond to different states of the terminal device. In one implementation, the duration can be used to determine whether the terminal device is in heating mode; in another implementation, the duration can be used to determine the amount of heat generated by the terminal device while maintaining the heating mode.

[0099] In this embodiment, once the indoor temperature is reached, the indoor unit's heating is activated first, while the terminal equipment's heating is deactivated. This helps ensure effective indoor heating while reducing energy consumption of the heating system. Adjusting the terminal equipment's heating capacity based on the indoor temperature after the indoor temperature is reached helps prevent the terminal equipment's heating capacity from being too high or too low, thus ensuring effective indoor heating while reducing system energy consumption. When the indoor temperature is not yet reached, the duration of this period accurately reflects whether the indoor unit's heating capacity is sufficient. Therefore, adjusting the terminal equipment's heating status according to the duration of this period allows for coordinated operation between the terminal equipment and the indoor unit, ensuring sufficient heating to meet the desired indoor heating effect.

[0100] In other embodiments, if the temperature state includes a state where the temperature has not been reached, the heating system can be controlled to put the terminal device into a heating state; or, if the temperature state includes a state where the temperature has been reached, both the indoor unit and the terminal device can stop heating.

[0101] In one feasible implementation of this embodiment, the heating system further includes a heating device and a refrigerant circulation loop. Both the heating device and the terminal device are located within the refrigerant circulation loop. The step of controlling the heating system to adjust the heating capacity of the terminal device based on the actual indoor temperature of the indoor space includes:

[0102] Adjust the target refrigerant temperature of the refrigerant circulation loop and / or the refrigerant flow rate of the terminal equipment according to the actual indoor temperature.

[0103] In this embodiment, the target refrigerant temperature can be the target outlet temperature of the heating device in the refrigerant circulation loop. In other embodiments, the target refrigerant temperature can also be the target value of the inlet temperature of the terminal device in the refrigerant circulation loop or the target value of the inlet temperature of the heating device, and so on.

[0104] In one implementation, when a fixed-frequency circulating pump is used in the refrigerant circulation loop, the target refrigerant temperature of the circulation loop is adjusted according to the actual indoor temperature. In another implementation, when a variable-frequency circulating pump is used in the refrigerant circulation loop, the target refrigerant temperature is adjusted according to the actual indoor temperature, and the operation of the variable-frequency circulating pump is controlled according to the actual indoor temperature (the operating speed, current, or power of the variable-frequency circulating pump can be adjusted according to the actual indoor temperature) to adjust the refrigerant flow rate in the terminal equipment.

[0105] In this embodiment, when the temperature difference between the actual indoor temperature and the target indoor temperature is greater than or equal to a preset temperature difference threshold, the target refrigerant temperature is reduced and / or the refrigerant flow rate is reduced; and / or, when the temperature difference between the actual indoor temperature and the target indoor temperature is less than the preset temperature difference threshold, the target refrigerant temperature is increased and / or the refrigerant flow rate is increased.

[0106] The temperature difference here is the difference between the actual indoor temperature and the target indoor temperature. When the temperature difference is greater than or equal to the preset temperature difference threshold, it indicates that the indoor heat is sufficient and the indoor environment is relatively comfortable; when the temperature difference is less than the preset temperature difference threshold, it indicates that the indoor heat is insufficient and the indoor environment is relatively uncomfortable.

[0107] The parameter adjustment values ​​corresponding to the process of reducing the target refrigerant temperature and / or refrigerant flow rate, or increasing the target refrigerant temperature and / or refrigerant flow rate, can be preset fixed values ​​or adjustment values ​​determined according to the actual operation of the environmental control system. For example, the parameter adjustment value can be determined according to the temperature difference between the actual indoor temperature and the target indoor temperature, and the target refrigerant temperature and / or refrigerant flow rate can be increased or decreased according to the parameter adjustment value.

[0108] In this embodiment, the target refrigerant temperature and / or refrigerant flow rate are adjusted to adapt to the indoor temperature, thereby ensuring that the heating capacity of the terminal equipment can be accurately matched with the indoor temperature requirement after the indoor temperature is reached, so that the indoor temperature can be stabilized at a comfortable temperature.

[0109] In other embodiments, the target refrigerant temperature and / or the target refrigerant flow rate of the terminal device may be determined based on the temperature range of the actual indoor temperature; or, the target refrigerant temperature and / or the target refrigerant flow rate may be calculated from the actual indoor temperature.

[0110] In one feasible embodiment of this example, the method further includes: determining a target refrigerant temperature range according to the type of the terminal device; the step of adjusting the target refrigerant temperature of the refrigerant circulation loop according to the actual indoor temperature includes: adjusting the target refrigerant temperature within the target refrigerant temperature range according to the actual indoor temperature.

[0111] In this embodiment, the terminal device includes a radiant terminal, which may be a radiator or underfloor heating system. In other embodiments, the terminal device may also be a radiant terminal or a convection terminal.

[0112] Different types of terminal devices correspond to different target refrigerant temperature ranges. In this embodiment, when the terminal device is a floor heating terminal, a first temperature range is determined as the target refrigerant temperature range; when the terminal device is a radiator terminal, a second temperature range is determined as the target refrigerant temperature range. The upper limit of the first temperature range is less than the upper limit of the second temperature range, and the lower limit of the first temperature range is less than the lower limit of the second temperature range. For example, the upper limit of the first temperature range is [50℃, 60℃], the lower limit is [30℃, 40℃], the upper limit of the second temperature range is [65℃, 80℃], and the lower limit of the first temperature range is [40℃, 55℃]. The first and second temperature ranges can be preset fixed temperature ranges, or they can be temperature ranges determined based on the actual operation of the environmental control system. For example, the first and second temperature ranges can be determined based on the status parameters representing the current heating capacity of the indoor units in the same indoor space.

[0113] Specifically, after adjusting the target refrigerant temperature based on the actual indoor temperature, a new reference value for the target refrigerant temperature is obtained. When the reference value is less than the lower limit of the target refrigerant temperature range, the lower limit is used as the new target refrigerant temperature to control the operation of the heating system. When the reference value is greater than the upper limit of the target refrigerant temperature range, the upper limit is used as the new target refrigerant temperature to control the operation of the heating system. When the reference value is within the target refrigerant temperature range, the reference value is used as the new target refrigerant temperature to control the operation of the heating system.

[0114] In this embodiment, the above method helps to ensure that when different types of terminal devices are used in the heating system, the heating capacity of the terminal devices will not be too large or too small, and both heating efficiency and energy saving can be effectively balanced.

[0115] In other embodiments, when the terminal device is a radiating terminal, a third temperature range is determined as the target refrigerant temperature range; when the terminal device is a convective terminal, a fourth temperature range is determined as the target refrigerant temperature range, wherein the upper limit of the third temperature range is less than the upper limit of the fourth temperature range, and the lower limit of the third temperature range is less than the lower limit of the fourth temperature range.

[0116] In one feasible implementation, the method further includes: determining a target duration based on the type of the terminal device; after the step of adjusting the target refrigerant temperature of the refrigerant circulation loop and / or the refrigerant flow rate of the terminal device based on the actual indoor temperature, the method further includes:

[0117] After the target time interval, return to the step of adjusting the target refrigerant temperature of the refrigerant circulation loop and / or the refrigerant flow rate of the terminal device according to the actual indoor temperature.

[0118] Different types correspond to different target durations. In this embodiment, when the terminal device is a floor heating terminal, a first duration is determined as the target duration; when the terminal device is a radiator terminal, a second duration is determined as the target duration; wherein, the first duration is longer than the second duration.

[0119] For example, the range of the first duration is [30 minutes, 2 hours], and the range of the second duration is [5 minutes, 30 minutes].

[0120] The first and second durations can be preset fixed durations, or durations determined based on the actual operation of the environmental control system. For example, the first and second durations can be determined based on the status parameters representing the current heating capacity of the indoor unit in the same indoor space and the air outlet direction of the indoor unit.

[0121] In this embodiment, different types of terminals adjust the indoor temperature at different rates. Different adjustment cycles are set for different types to adjust the heating capacity of the terminal devices. This helps to maintain a comfortable indoor temperature while improving system stability and saving system energy.

[0122] In other embodiments, when the terminal device is a radiative terminal, a third duration is determined as the target duration; when the terminal device is a convective terminal, a fourth duration is determined as the target duration, wherein the third duration is longer than the fourth duration.

[0123] Based on any of the above embodiments, in the second embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. Based on this, the step of adjusting the heating state of the terminal device according to the duration of the non-temperature-reached state includes:

[0124] When the duration is less than or equal to a preset duration threshold, the heating system is controlled to stop the terminal equipment from heating or maintain the stopped heating state; and / or,

[0125] When the duration exceeds the preset duration threshold, the heating system is controlled to start or maintain the heating state of the terminal device.

[0126] The preset duration threshold is a critical value used to distinguish whether the heating capacity of the indoor unit is sufficient. The preset duration threshold can be a fixed value set in advance, or it can be a parameter value determined according to the actual operation of the environmental control system. For example, the preset duration threshold can be determined based on at least one of the following parameters: the temperature difference between indoor and outdoor environments where the environmental control system is located, the temperature difference between indoor temperature and set temperature, and the heating duration of the indoor unit.

[0127] If the duration is less than or equal to the preset duration threshold, it indicates that the indoor unit has sufficient heating capacity. The indoor unit maintains heating while the terminal device stops heating; when the terminal device maintains heating, it can increase the heating capacity or maintain the current heating capacity.

[0128] If the duration exceeds the preset threshold, it indicates that the indoor unit's heating capacity is insufficient. In this case, the indoor unit maintains heating mode during the terminal device's heating process. When the terminal device starts or maintains heating mode, it can control the heating system's operation based on preset operating parameters corresponding to a fixed heating capacity, or it can control the heating system's operation based on the target heating capacity corresponding to the actual operating status of the air conditioner. When the terminal device maintains heating mode, it can increase the heating capacity or maintain the current heating capacity.

[0129] Among them, when the duration is longer than the preset duration threshold, the heating capacity of the indoor unit can be greater than or equal to the heating capacity of the indoor unit when the duration is less than or equal to the preset duration threshold.

[0130] In this embodiment, by means of the above method, when the heating capacity of the indoor unit is insufficient, the terminal equipment can effectively make up for the insufficient capacity of the indoor unit in a timely manner to ensure the indoor heating effect; and when the heating capacity of the indoor unit is sufficient, the terminal equipment can stop heating, which is conducive to ensuring the indoor heating effect while saving energy consumption.

[0131] In one feasible implementation of this embodiment, after the step of obtaining the temperature state of the indoor space, the method further includes: if the temperature state includes a state where the temperature has not been reached, controlling the heat pump system to operate so that the heating capacity of the indoor unit is greater than the preset heating capacity.

[0132] The indoor unit's heating capacity exceeding the preset heating capacity means that the indoor unit is outputting its maximum heating capacity. The preset heating capacity can be 50% to 80% of the indoor unit's maximum heating capacity. In this embodiment, the indoor unit's heating capacity can be changed by altering its set temperature; for example, increasing the set temperature can increase the indoor unit's heating capacity.

[0133] In this embodiment, the temperature state includes controlling the heat pump system to achieve maximum heating capacity of the indoor unit when the temperature has not yet been reached. In this embodiment, the heat pump system operation control method includes at least one of the following: controlling the compressor's highest operating frequency, controlling the outdoor fan's highest operating speed, and controlling the indoor fan's highest operating speed.

[0134] It should be noted that, regardless of whether the duration of the temperature condition is greater than the preset duration threshold, the heat pump system will be controlled to operate so that the heating capacity of the indoor unit is greater than the preset heating capacity, even if the temperature condition is not reached.

[0135] In this embodiment, when the indoor temperature has not yet been reached, the indoor unit outputs a large amount of heat, which helps to ensure the indoor heating efficiency and thus ensure the indoor heating effect.

[0136] In one feasible implementation of this embodiment, the step of controlling the heating system to start or maintain the heating state of the terminal device when the duration exceeds the preset duration threshold includes: controlling the heating system to operate so that the heating capacity of the terminal device is greater than the preset heating capacity when the duration exceeds the preset duration threshold.

[0137] The heating capacity of the terminal device is greater than the preset heating capacity, meaning that the terminal device outputs its maximum heating capacity. The preset heating capacity can be 50% to 80% of the maximum heating capacity of the terminal device.

[0138] In this embodiment, when the duration of the unheated state exceeds a preset duration threshold, the heating system is controlled to operate so that the heating capacity of the terminal device reaches its maximum. In this embodiment, the heating system operation control method includes at least one of the following: the heating equipment operates at its highest power, the target refrigerant temperature in the refrigerant circulation loop is the highest refrigerant temperature, the refrigerant pump in the refrigerant circulation loop operates at its maximum speed, etc.

[0139] In this embodiment, when the indoor temperature has not yet been reached, the terminal device outputs a large amount of heat, which helps to ensure the indoor heating efficiency and thus ensure the indoor heating effect.
