[0074] In existing technologies, when a heat pump system and a heating system are installed simultaneously in an indoor space, the heating system and the heat pump system generally operate independently and according to the parameters configured by the user.

[0112] In this embodiment, step S10 is executed when the intelligent supplementary heating function of the environmental control system is activated, and the heating system is in standby mode when the intelligent supplementary heating function is activated. The intelligent supplementary heating function indicates that the indoor space where the indoor unit and the terminal device are located have a dual-device linkage heating demand. In this embodiment, the intelligent supplementary heating function is activated in response to a user command, for example, the user can click an icon to input a command to activate the intelligent supplementary heating function. In other embodiments, the intelligent supplementary heating function may also be activated when the user status in the indoor space reaches a preset state or when it is detected that the user is about to enter the indoor space.
[0113] Step S20: Control the operation of the heat pump system and the heating system according to the control strategy corresponding to the first temperature state parameter, so as to adjust the heating capacity of the indoor unit and / or the terminal device, wherein different first temperature state parameters correspond to different control strategies.
[0114] The control strategy may include the target state that the indoor unit and the terminal equipment need to achieve for heating (target heating capacity or whether heating is required, etc.) and the target control method of the corresponding system when the indoor unit and the terminal equipment achieve the target state (e.g., the target operating parameters of the components in the corresponding system or the control basis for adjusting the operating parameters of the components in the corresponding system, etc.). The control strategy may include one of the following: both the terminal equipment and the indoor unit are in heating mode; one of the terminal equipment and the indoor unit is in heating mode (the terminal equipment is heating and the indoor unit is not heating, or the terminal equipment is not heating and the indoor unit is heating, etc.); the terminal equipment and the indoor unit maintain their current state; the terminal equipment increases the heating capacity and the indoor unit decreases the heating capacity; the terminal equipment decreases the heating capacity and the indoor unit increases the heating capacity, etc.
[0115] Different control strategies place different weights on energy saving and comfort effects in the process of balancing energy saving and comfort effects. Some control strategies place greater emphasis on energy saving, while others place greater emphasis on comfort effects.
[0116] Different first temperature state parameters correspond to different control strategies. In one implementation, the target parameter range in which the first temperature state parameter lies can be determined, and the strategy associated with the target parameter range can be used as the control strategy. In another implementation, the quantitative relationship between the first temperature state parameter and the target parameter can be determined, and the control strategy can be determined based on this quantitative relationship.
[0117] The methods for adjusting the heating capacity of the indoor unit during the operation of a heat pump system according to the determined control strategy may include at least one of the following: adjusting the compressor operating frequency, adjusting the operating speed of the indoor fan in the indoor unit, adjusting the set temperature of the indoor unit, adjusting the opening of the electronic expansion valve between the indoor heat exchanger and the outdoor heat exchanger, switching the indoor unit on and off, etc.
[0118] The methods for adjusting the heating capacity of the terminal equipment during the operation of the heating system according to the determined control strategy may include at least one of the following: switching the heating equipment on and off, adjusting the heating control parameters of the heating equipment, adjusting the amount of refrigerant flowing into the terminal equipment (e.g., adjusting the opening degree of the corresponding sub-regulation module and / or the speed of the circulating pump in the refrigerant circulation loop, etc.), and adjusting the target refrigerant temperature in the refrigerant circulation loop (e.g., the target outlet temperature of the heating equipment and / or the target inlet temperature of the terminal equipment and / or the target return temperature of the heating equipment, etc.).
[0119] When the environmental control system regulates more than one indoor space, the heating capacity of the indoor unit and terminal equipment in each indoor space is determined based on the corresponding first temperature state parameter to determine the corresponding control strategy, and the operation of the heat pump system and heating system is controlled according to the control strategy of all indoor spaces.
[0120] This embodiment provides a control method for an environmental regulation system. When an indoor unit of a heat pump system and a terminal device of a heating system are installed in an indoor space, the two systems no longer operate independently. Instead, they are controlled by a control strategy that adapts to the actual temperature parameters of their respective environments to adjust the heat output of the indoor unit and the terminal device in the indoor space. This allows the two separate systems to operate in a coordinated manner, ensuring that the heat supply is neither too high nor too low, thereby effectively improving energy efficiency and indoor comfort.
[0121] In one feasible implementation, the first temperature state parameter includes the indoor temperature of the indoor space, with reference to... Figure 4 Step S20 may include steps S21 and / or S22:
[0122] S21, if the indoor temperature does not meet the temperature reaching condition, or if the first temperature state parameter does not meet the temperature reaching condition and the environmental regulation system meets the preset heating condition, the heat pump system and the heating system are controlled to operate with a first control strategy. The first control strategy includes the indoor unit and the terminal device being in heating state.
[0123] In this embodiment, the temperature reaching condition includes the indoor temperature and the set temperature being greater than a fourth preset temperature difference. This fourth preset temperature difference is a threshold value used to distinguish whether the indoor temperature has reached a user comfort level. If the indoor temperature and the set temperature are greater than the fourth preset temperature difference, it indicates that the indoor temperature has reached a user comfort level; if the indoor temperature and the set temperature are less than or equal to the fourth preset temperature difference, it indicates that the indoor temperature has not reached a user comfort level.
[0124] The situations in which the indoor temperature or the first temperature state does not meet the temperature reaching conditions include: the temperature difference between the indoor temperature and the set temperature is less than the set temperature difference, and / or, the indoor temperature is less than the first set temperature; and / or, the situations in which the indoor temperature or the first temperature state does not meet the temperature reaching conditions include: the duration of the heating operation of the environmental control system is greater than or equal to the set duration, the temperature difference between the indoor temperature and the set temperature is less than the set temperature difference, and / or, the indoor temperature is less than the sum of the first set temperature and the preset temperature value, wherein the preset temperature value is a temperature value greater than 0. The preset heating conditions include: the return air temperature detected by the return air temperature sensor of the indoor unit is less than the preset return air temperature; and / or, the preset heating conditions include: the duration of heating operation of the environmental control system is greater than or equal to the set duration, the temperature difference between the indoor temperature and the set temperature is less than the set temperature difference, and / or, the indoor temperature is less than the sum of the first set temperature and the preset temperature, wherein the preset temperature value is a temperature value greater than 0; and / or, the preset heating conditions include: the duration of heating operation of the environmental control system is less than the set duration, the temperature difference between the indoor temperature and the set temperature is less than the set temperature difference, and / or, the indoor temperature is less than the first indoor temperature, and the first indoor temperature is less than or equal to the first set temperature. The conditions under which the indoor temperature meets the temperature requirement include: the indoor temperature is greater than or equal to the minimum of the set temperature and the second indoor temperature, and the duration of this condition is greater than the target duration; and / or, the conditions under which the indoor temperature meets the temperature requirement include: the indoor temperature is greater than or equal to the second indoor temperature, and the cumulative heating time of the indoor unit is greater than the first duration; and / or, the conditions under which the indoor temperature meets the temperature requirement include: the temperature difference between the indoor temperature and the set temperature is greater than the set temperature difference; and / or, the conditions under which the indoor temperature meets the temperature requirement include: the indoor temperature is greater than the second set temperature, and the second set temperature is greater than the first set temperature.
[0125] Among them, the temperature conditions can be set according to the current trend of indoor temperature change. The fourth preset temperature difference when the indoor temperature increases (e.g., 1℃) can be greater than the fourth preset temperature difference when the indoor temperature decreases (e.g., -1℃).
[0126] The steps for controlling the operation of the heat pump system and the heating system using the first control strategy include: when the indoor unit is currently in a state of not heating and the terminal equipment is in a state of heating, controlling the heat pump system to start the heating operation of the indoor unit; when the indoor unit is currently in a state of heating and the terminal equipment is not heating, controlling the heating system to start the heating operation of the terminal equipment; when both the indoor unit and the terminal equipment are currently in a state of heating, controlling the operation of the heat pump system and the heating system to maintain the heating state of both the indoor unit and the terminal equipment, wherein, during the process of maintaining the heating state of the indoor unit and the terminal equipment, the heating capacity can be increased (e.g., increasing the fan speed of the indoor unit and / or increasing the set temperature of the indoor unit, etc.) or the current heating capacity can be maintained; when both the indoor unit and the terminal equipment are currently not heating, controlling the operation of the heat pump system and the heating system to start the heating of the indoor unit and start the heating of the terminal equipment.
[0127] In this embodiment, the first control strategy further includes: when both the indoor unit and the terminal device are in heating mode, controlling the operating fan speed of the indoor unit to be greater than or equal to a preset fan speed. The preset fan speed corresponds to 50% of the maximum fan speed of the indoor unit. In this embodiment, the indoor fan can be controlled to operate at the highest fan speed. The operating fan speed can be a user-defined setting, for example, 60% of the maximum fan speed.
[0128] S22, when the indoor temperature meets the temperature requirement, the heat pump system and / or the heating system are controlled to operate according to a second control strategy. The second control strategy includes adjusting the heating capacity of the indoor unit and / or the terminal device according to a first operating state of the terminal device and the indoor unit and / or a first state parameter representing the energy efficiency relationship between the terminal device and the indoor unit.
[0129] The indoor heating efficiency corresponding to the first control strategy is greater than that corresponding to the second control strategy; the system energy-saving effect corresponding to the second control strategy is greater than that corresponding to the first control strategy.
[0130] In this embodiment, the first operating state includes whether the terminal device is in heating mode and whether the indoor unit is in heating mode. In other embodiments, the first operating state may also include the current heating capacity of the terminal device (e.g., the current surface temperature of the terminal device and / or the target refrigerant temperature, etc.) and the current heating capacity of the indoor unit (e.g., the current fan speed and / or the current set temperature of the indoor unit, etc.), etc.
[0131] The energy efficiency relationship is the relationship between the heating energy efficiency of the terminal equipment and the heating energy efficiency of the indoor unit. The first state parameter may include at least one state parameter reflecting the energy efficiency relationship between the two devices, such as environmental parameters of the environment in which the heat pump system and the heating system are located (e.g., ambient temperature), and operating parameters of the heat pump system and the heating system themselves (e.g., electrical power during the heating process, rated capacity, etc.).
[0132] Different first operating states and / or different first state parameters correspond to different heating capacities of indoor units and terminal devices.
[0133] It should be noted that there is no specific restriction on the order in which steps S21 and S22 are executed.
[0134] In this embodiment, when the indoor temperature reaches the set temperature, the indoor unit and the terminal equipment heat simultaneously, which helps to ensure indoor heating efficiency and improve indoor comfort. When the indoor temperature does not reach the set temperature, the heating output of the indoor terminal equipment and the terminal equipment is adjusted according to the current operating status of the equipment and / or the energy efficiency relationship between the equipment, which helps to effectively balance the energy efficiency of equipment operation and indoor comfort.
[0135] In other embodiments, the heat pump system and heating system may be controlled by a first control strategy when the indoor temperature is in a first temperature range; the heat pump system and heating system may be controlled by a third control strategy when the indoor temperature is in a second temperature range; and the heat pump system and heating system may be controlled by a second control strategy when the indoor temperature is in a third temperature range. The temperature in the first temperature range is lower than the temperature in the second temperature range, and the temperature in the second temperature range is lower than the temperature in the third temperature range. The third control strategy may include maintaining the indoor unit and terminal equipment in their current state of operation.
[0136] In other embodiments, when the indoor temperature meets the temperature requirement, a third control strategy can also be used to control the operation of the heat pump system and the heating system. The third control strategy includes one of the indoor unit and the terminal device being in heating mode and the other of the indoor unit and the terminal device being stopped from heating.
[0137] In one feasible implementation, the first control strategy further includes: when both the indoor unit and the terminal device are in heating mode, acquiring the indoor ambient temperature of the indoor space; adjusting the current set temperature of the indoor unit according to the indoor ambient temperature to obtain a new set temperature of the indoor unit; and controlling the operation of the heat pump system according to the new set temperature.
[0138] Different indoor ambient temperatures correspond to different new set temperatures. The new set temperature must be greater than or equal to the current set temperature of the indoor unit.
[0139] In one implementation, the target set temperature can be determined based on the indoor ambient temperature, and the target set temperature can be used as the new set temperature. In another implementation, the temperature adjustment value of the current set temperature can be determined based on the indoor ambient temperature, and the current set temperature can be adjusted based on the temperature adjustment value to obtain the new set temperature.
[0140] In this embodiment, the temperature difference between the indoor ambient temperature and the current set temperature of the indoor unit is determined; a new set temperature is then determined based on this temperature difference. Specifically, if the temperature difference is greater than a first preset temperature difference, the indoor ambient temperature is increased by a preset temperature adjustment value to obtain the new set temperature; if the temperature difference is less than or equal to a second preset temperature difference, the current set temperature of the indoor unit is determined as the new set temperature. The preset temperature adjustment value is greater than the absolute value of the first preset temperature difference.
[0141] In this embodiment, the indoor unit's current set temperature is adjusted according to the indoor ambient temperature, which helps ensure that the indoor unit's heat supply accurately matches the actual indoor heating demand, effectively improving indoor comfort. Specifically, when the temperature difference between the indoor ambient temperature and the set temperature is greater than the preset temperature difference, the indoor ambient temperature is increased to obtain a new set temperature; otherwise, the set temperature is maintained unchanged, forcing the indoor unit to have heating energy demand, ensuring that the indoor unit maintains heating operation to quickly adjust the indoor temperature to the user's comfortable state.
[0142] In other embodiments, the indoor fan speed and / or compressor operating frequency and / or the opening degree of the electronic expansion valve in the indoor unit may also be adjusted according to the indoor ambient temperature, etc.
[0143] In one feasible implementation, the first state parameter includes a first outdoor temperature. The step of adjusting the heating capacity of the indoor unit and / or the terminal device according to the first state parameter representing the energy efficiency relationship between the terminal device and the indoor unit includes: when the first outdoor temperature is greater than a first preset temperature, controlling the indoor unit to be in heating mode and the terminal device to stop heating; and / or, when the first outdoor temperature is less than or equal to a second preset temperature, controlling both the indoor unit and the terminal device to maintain their current state; wherein the second preset temperature is less than or equal to the first preset temperature.
[0144] The first outdoor temperature is the current outdoor ambient temperature, detected by the aforementioned outdoor sensor.
[0145] The first preset temperature and the second preset temperature are the outdoor temperature thresholds used to distinguish the energy efficiency of the terminal device and the indoor unit.
[0146] When the first outdoor temperature is less than or equal to the second preset temperature, if the indoor unit is currently heating and the terminal device is not heating, then the indoor unit will continue to heat and the terminal device will continue to stop heating; if both the indoor unit and the terminal device are currently heating, then both the indoor unit and the terminal device will continue to heat; if the indoor unit is currently not heating and the terminal device is heating, then the indoor unit will continue to stop heating and the terminal device will continue to heat.
[0147] In this embodiment, when the first outdoor temperature is greater than the first preset temperature (e.g., 0°C), the heating efficiency of the indoor unit is greater than that of the terminal device, and the system's heat load is low at this time. Therefore, the terminal device stops heating, and the indoor unit with higher energy efficiency is used for heating, which helps to effectively improve the system's energy-saving effect while ensuring indoor comfort. When the first outdoor temperature is less than or equal to the second preset temperature (e.g., -3°C), the indoor unit does not have an energy-saving advantage in heating, but the heating demand to maintain the room at the desired temperature is greater at this time. Based on this, the system maintains its current operation to ensure that the room can be maintained at the desired temperature and improve indoor comfort.
[0148] In other embodiments, a target relationship between the heating capacity of the indoor unit and the heating capacity of the terminal equipment can be determined based on the first outdoor temperature, and the operation of the heat pump system and the heating system can be controlled according to the target relationship.
[0149] In one feasible embodiment, the step of adjusting the heating capacity of the indoor unit and / or the terminal device according to the first operating state of the terminal device and the indoor unit and / or the first state parameter representing the energy efficiency relationship between the terminal device and the indoor unit includes: when the first operating state is a preset state, controlling both the indoor unit and the terminal device to maintain the current state; when the first operating state is a state other than the preset state, adjusting the heating capacity of the indoor unit and the terminal device according to the first state parameter; wherein, the preset state includes the indoor unit being in a heating state and the terminal device not being in a heating state.
[0150] Maintaining the current state for both the indoor unit and the terminal equipment means that the indoor unit continues to heat while the terminal equipment remains off.
[0151] The process of adjusting the heating capacity of the indoor unit and the terminal equipment according to the first state parameters can be implemented in the manner mentioned in the above embodiments, and will not be elaborated here.
[0152] In this embodiment, when the indoor unit is heating independently when the room reaches the set temperature, the indoor unit maintains heating while the terminal devices remain off, without switching to a state where only the terminal devices are used for heating. This effectively avoids a drop in indoor temperature due to insufficient heating caused by thermal inertia during the transition of the terminal devices from off to on. Furthermore, operating the indoor unit independently for heating is energy-efficient. Based on this, the system's energy-saving effect is ensured while maintaining the indoor temperature at a level that meets user comfort requirements, achieving both energy savings and improved indoor comfort. When the room reaches the set temperature and both the indoor unit and the terminal devices are heating, or the terminal devices are heating independently, the system further controls the coordinated operation of the two systems based on their energy efficiency relationship under current operating conditions, thereby further ensuring a balance between energy efficiency and comfort.
[0153] In other embodiments, when the first operating state is a preset state, both the indoor unit and the terminal device are controlled to maintain the current state; when the first operating state is a state other than the preset state, one of the indoor unit and the terminal device is in a heating state, and the other of the indoor unit and the terminal device stops heating.
[0154] In one feasible embodiment, the first control strategy further includes: when the indoor unit is in forced heating mode and the terminal device is in heating mode, determining a new target water temperature for the heating system based on the maximum value of the sum of the target water temperature and the preset temperature rise and the maximum water temperature; and controlling the operation of the heating system based on the new target water temperature.
[0155] Here, "indoor unit in forced heating mode" means that the indoor unit maintains heating operation regardless of the indoor temperature.
[0156] The target water temperature is the target value of the water temperature in the refrigerant circulation loop of the heating system.
[0157] During the operation of the heating system controlled by the new target water temperature, the current water temperature of the refrigerant circulation loop can be obtained. Based on the current water temperature and the new target water temperature, the operating parameters of the gas equipment in the heating system and / or the operating parameters (opening or closing or flow rate, etc.) of the corresponding water distribution valves connected to the terminal equipment can be adjusted.
[0158] In this embodiment, when both the indoor unit and the terminal device are in heating mode, the above method helps to ensure that the indoor unit and the terminal device work together to generate enough heat to quickly raise the indoor temperature and improve indoor comfort.
[0159] In other embodiments, when the indoor unit is in a state of not heating and the terminal device is in a state of heating, the target water temperature of the heating system can be automatically adjusted within a preset temperature range according to the temperature of the indoor space, and the operation of the heating system can be controlled according to the obtained target water temperature.
[0160] Based on any of the above embodiments, in the second embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. In addition, after the step of controlling the operation of the heat pump system and the heating system with the first control strategy, the method further includes:
[0161] When the temperature in the indoor space meets the target comfort conditions, the operation of the heat pump system and the heating system controlled by the first control strategy is stopped.
[0162] The target comfort conditions can be preset fixed conditions or conditions determined based on the actual operation of the system. Target comfort conditions may include the target temperature range that the indoor space temperature needs to meet, the target duration that the indoor temperature needs to remain at the preset conditions, or the target relationship between the indoor space temperature and the preset temperature, etc.
[0163] After the operation of the heat pump system and heating system is stopped under the first control strategy, the heat pump system and heating system can resume operation in the state before the first control strategy was applied. Alternatively, the heat pump system and heating system can be controlled according to the actual operation of the system. Or, the heat pump system and heating system can operate in a preset manner (e.g., the indoor unit stops heating while the terminal equipment continues to heat; or the indoor unit heats up while the terminal equipment stops heating, etc.).
[0164] In this embodiment, when the indoor temperature is adjusted to a more comfortable state, the first control strategy is no longer used, and the indoor unit and terminal equipment are no longer forced to heat at the same time, which is conducive to effectively improving the balance between energy saving and comfort of the system.
[0165] In one feasible implementation, after the step of controlling the operation of the heat pump system and the heating system with the first control strategy, the method further includes: acquiring a frequency parameter, the frequency parameter representing the number of times the first control strategy is used between the start time of the environmental conditioning system heating the indoor space and the current time; and determining the target comfort conditions based on the frequency parameter.
[0166] In this embodiment, the frequency parameter includes the number of times it is used. In other embodiments, it may also include the number of times the environmental control system determines that the indoor temperature has not met the temperature-reaching conditions between the start time of heating the indoor space and the current time, etc. Each time the first control strategy is activated, the number of uses increases by one.
[0167] Different frequency parameters correspond to different target comfort conditions. The parameter range in which the frequency parameter is located can be determined, and the target comfort conditions can be determined based on the parameter range; or, the target temperature value that needs to be achieved in the indoor space can be calculated based on the frequency parameter.
[0168] In this embodiment, when the frequency parameter is less than or equal to a preset parameter value, the target comfort condition is determined to include a temperature difference between the indoor space temperature and the set temperature of the indoor unit that is greater than or equal to a second preset temperature difference.
[0169] In this embodiment, when the frequency parameter is greater than a preset parameter value, determining the target comfort condition includes at least one of the following:
[0170] Condition 1: The temperature difference between the indoor space temperature and the set temperature of the indoor unit is greater than or equal to a third preset temperature difference, and the third preset temperature difference is greater than the second preset temperature difference.
[0171] Condition 2: The temperature of the indoor space is greater than the upper limit of comfort temperature or the temperature of the indoor space is greater than the upper limit of comfort temperature for a first preset duration, wherein the upper limit of comfort temperature is greater than the set temperature.
[0172] Condition 3: The temperature of the indoor space is greater than the upper limit of the comfort temperature and the timing duration reaches the target duration. The timing duration is the duration during which the current set temperature of the indoor unit is used to control the operation of the indoor unit.
[0173] Regarding condition 1, the set temperature is the target temperature that the indoor environment needs to reach during the indoor unit's heating process. The set temperature can be the initial set temperature set by the user based on their needs, or a new set temperature obtained by modifying the initial set temperature as described above. The third preset temperature difference can be equal to the fourth preset temperature difference mentioned above. For example, the third preset temperature difference is 0℃, and the second preset temperature difference is -0.5℃.
[0174] Regarding condition 2, the upper limit temperature of comfort is the upper limit temperature of the comfort temperature range that meets the user's comfort needs. The comfort temperature range can be a fixed range that is preset, or it can be a range determined according to the deviation between the set temperature and the preset temperature. For example, the comfort temperature range is [set temperature - preset temperature deviation, set temperature + preset temperature difference], etc.
[0175] Regarding condition 3, the time elapsed from the initial moment when the indoor unit's current set temperature was generated to the current moment is the timing duration. The timing duration restarts when the indoor unit's set temperature is adjusted. The target duration can be a pre-set fixed duration or a duration determined based on the actual operating conditions of the environmental control system. In this embodiment, the target duration is determined based on the heating duration of the terminal device.
[0176] In this embodiment, the frequency parameter accurately reflects the frequency at which the environmental control system enters the pre-temperature control state. This frequency parameter setting is adapted to the target comfort conditions for exiting the pre-temperature control state, which helps improve the accuracy of the target comfort conditions. It also prevents the environmental control system from entering the pre-temperature control state too frequently and avoids indoor overheating when exiting the pre-temperature control state, thereby ensuring indoor comfort while improving system operational stability. Specifically, the more frequent the pre-temperature control state, the more stringent the exit conditions (i.e., the higher the indoor temperature), which helps reduce the frequency of the system entering the pre-temperature control state, effectively ensuring indoor comfort while improving system operational stability.
[0177] In other embodiments, target comfort conditions can also be preset, including the temperature difference between the indoor space temperature and the set temperature of the indoor unit being greater than or equal to the target temperature difference. This target temperature difference can be calculated based on the frequency parameter, which is positively correlated with the frequency parameter, and so on.
[0178] In one feasible embodiment, the method further includes: determining the duration difference between a preset heating duration and the heating operation duration of the terminal device; determining the target duration based on the maximum duration between the duration difference and a second preset duration; wherein the preset heating duration is a pre-set time required for the temperature rise of the indoor space from the moment the terminal device is turned on to a value greater than a preset value.
[0179] The preset heating time reflects the thermal inertia of the terminal equipment. The second preset time is the time required for the indoor space temperature to reach the preset temperature after the terminal equipment and indoor unit heat up simultaneously.
[0180] The duration difference reflects the current heating effect of the terminal equipment on the room.
[0181] In this embodiment, by using the above method, when the indoor unit and the terminal device are simultaneously supplying heat to the room, it is beneficial to ensure that the heat output between the two devices can be coordinated and cooperated, thereby effectively improving the indoor heating efficiency when the temperature has not yet been reached.
[0182] Based on any of the above embodiments, in the third 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, after the step of stopping the operation of the heat pump system and the heating system controlled by the first control strategy, the method further includes: controlling the operation of the heat pump system and the heating system according to frequency parameters and / or a second state parameter representing the energy efficiency relationship between the terminal device and the indoor unit and / or a second operating state of the terminal device and the indoor unit in the initial stage, so as to adjust the heating capacity of the indoor unit and the terminal device;
[0183] The frequency parameter represents the number of times the first control strategy is used between the start time of the environmental regulation system's heating of the indoor space and the current time, and the initial stage is the stage before the heat pump system and the heating system are controlled by the first control strategy.
[0184] In this embodiment, the second operating state includes whether the terminal device is in heating mode and whether the indoor unit is in heating mode. In other embodiments, the second operating state may also include the current heating capacity of the terminal device (e.g., the current surface temperature of the terminal device and / or the target refrigerant temperature, etc.) and the current heating capacity of the indoor unit (e.g., the current fan speed and / or the current set temperature of the indoor unit, etc.), etc.
[0185] The energy efficiency relationship is the relationship between the heating energy efficiency of the terminal equipment and the heating energy efficiency of the indoor unit. The second state parameter may include at least one state parameter reflecting the energy efficiency relationship between the two devices, such as environmental parameters of the environment in which the heat pump system and the heating system are located (e.g., ambient temperature), and operating parameters of the heat pump system and the heating system themselves (e.g., electrical power during the heating process, rated capacity, etc.).
[0186] In this embodiment, the frequency parameter includes the number of times it is used. In other embodiments, it may also include the number of times the environmental control system determines that the indoor temperature has not met the temperature-reaching conditions between the start time of heating the indoor space and the current time, etc. Each time the first control strategy is activated, the number of uses increases by one.
[0187] In this embodiment, a target heating mode can be determined from at least two preset heating modes based on frequency parameters and / or second state parameters and / or second operating state. The operation of the heat pump system and the heating system is controlled according to the target heating mode. The at least two preset heating modes include: the terminal equipment and indoor unit are restored to the initial stage of heating state, the terminal equipment is heating and the indoor unit is not heating, the terminal equipment is not heating and the indoor unit is heating, the target equipment is selected from the terminal equipment and indoor unit according to the operating condition parameters and the target equipment is controlled to maintain heating, and the equipment other than the target equipment is not heating, etc.
[0188] In this embodiment, after exiting the temperature-not-reached control, the operation of the heat pump system and the heating system is controlled based on frequency parameters and / or second operating state and / or second state parameters. This helps to improve the heating coordination and accuracy of the heating between the indoor unit and the terminal equipment, so as to ensure that the indoor space can be maintained at a comfortable temperature for as long as possible and improve indoor comfort.
[0189] In other embodiments, after the step of stopping the operation of the heat pump system and the heating system under the first control strategy, the operation of the heat pump system and the heating system can also be directly controlled under the second control strategy.
[0190] In one feasible implementation, the step of controlling the operation of the heat pump system and the heating system based on a frequency parameter and / or a second state parameter representing the energy efficiency relationship between the terminal device and the indoor unit and / or a second operating state of the terminal device and the indoor unit in the initial stage includes: controlling the operation of the heat pump system and the heating system with the second control strategy when the frequency parameter is less than or equal to a preset parameter value; and controlling the operation of the heat pump system and the heating system based on the second state parameter and / or the second operating state when the frequency parameter is greater than the preset parameter value, so as to adjust the heating capacity of the indoor unit and the terminal device.
[0191] In this embodiment, when the second operating state is that one of the terminal device and the indoor unit is in heating state, the heat pump system and the heating system are controlled to operate in the operating state of the initial stage; when the second operating state is that both the terminal device and the indoor unit are in heating state, the heat pump system and the heating system are controlled to operate according to the second state parameters to adjust the heating capacity of the indoor unit and the terminal device.
[0192] In the second operating state, where either the terminal device or the indoor unit is in heating mode, if the indoor unit is heating and the terminal device stops heating in the initial stage, the heating system is controlled to stop the terminal device from heating, and the heat pump system is controlled to maintain the indoor unit's heating. If the indoor unit stops heating and the terminal device is heating in the initial stage, the heating system is controlled to maintain the terminal device's heating, and the heat pump system is controlled to stop the indoor unit from heating.
[0193] In one implementation, if the second state parameter satisfies the first condition that the indoor unit's thermal efficiency is greater than the terminal device's heating efficiency, the heat pump system and heating system are controlled to operate, so that the indoor unit maintains heating and the terminal device stops heating. In another implementation, if the second state parameter satisfies the second condition that the indoor unit's thermal efficiency is greater than the terminal device's heating efficiency, the heat pump system and heating system are controlled to operate, so that the indoor unit stops heating and the terminal device maintains heating. Alternatively, the target ratio of the indoor unit's and the terminal device's heating capacity is adjusted according to the second state parameter, and the heat pump system and heating system are controlled according to the target ratio.
[0194] In this embodiment, when the frequency of using the pre-temperature control is low, the temperature-reaching control strategy is directly used when exiting the pre-temperature control. When the frequency of using the pre-temperature control is high, the two systems are controlled to operate in coordination based on the heating status of the two devices and / or the energy efficiency relationship between the two devices before the indoor space enters the pre-temperature control. This helps to improve the accuracy of the heating of the indoor space by the two devices, extends the duration of the indoor space in a comfortable state, reduces the frequency of the system entering the pre-temperature control, and improves the stability of system operation while ensuring indoor comfort.
[0195] In other embodiments, when the second operating state is that one of the terminal device and the indoor unit is in a heating state, the heat pump system and the heating system can be controlled to operate in the operating state of the initial stage; when the second operating state is that both the terminal device and the indoor unit are in a heating state, the heat pump system and the heating system can be controlled to operate according to the second state parameters to adjust the heating capacity of the indoor unit and the terminal device.
[0196] In one feasible implementation, the second state parameter includes a second outdoor temperature. When the second outdoor temperature is greater than a first preset temperature, the heat pump system is controlled to operate so that the indoor unit maintains a heating state, and the heating system is controlled to operate so that the terminal device stops heating; and / or, when the first outdoor temperature is less than or equal to the second preset temperature, the heat pump system is controlled to operate so that the indoor unit stops heating, and the heating system is controlled to operate so that the terminal device maintains a heating state; wherein the second preset temperature is less than or equal to the first preset temperature.
[0197] The second outdoor temperature is the current outdoor ambient temperature, detected by the aforementioned outdoor sensor.
[0198] The first preset temperature and the second preset temperature are the outdoor temperature thresholds used to distinguish the energy efficiency of the terminal device and the indoor unit.
[0199] In this embodiment, when the second outdoor temperature is greater than the first preset temperature (e.g., 0°C), the heating efficiency of the indoor unit is greater than that of the terminal device, and the system's heat load is low at this time. Therefore, the terminal device stops heating, and the indoor unit with higher energy efficiency is used for heating, which helps to effectively improve the system's energy-saving effect while ensuring indoor comfort. When the second outdoor temperature is less than or equal to the second preset temperature (e.g., -3°C), the indoor unit does not have an energy-saving advantage in heating, but the heating demand to maintain the room at the desired temperature is greater at this time. Based on this, the system maintains its current operation to ensure that the room can be maintained at the desired temperature and improve indoor comfort.
[0200] In other embodiments, the second state parameter may also include the relationship between the heating efficiency of the terminal device and the heating efficiency of the indoor unit. Based on the relationship, a target device is determined among the indoor unit and the terminal devices. The target device maintains heating, while other devices stop heating.
