However, the opening and closing of terminal devices are generally controlled according to the user's input instructions. Users can choose to turn on some terminal devices or all terminal devices. However, such control methods are prone to mismatch between the operation of environmental control equipment and actual operating conditions, poor coordination between different types of terminal devices, resulting in insufficient heat exchange capacity of environmental control equipment, causing the indoor environment to deviate from the user's comfort state.

[0059] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Embodiments of the present invention

[0060] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0061] In this embodiment of the application, referring to Figures 1 and 2, the environmental control device includes a control device 1 and a terminal group 31. The terminal group 31 includes at least two types of terminal devices, which are used to regulate the indoor space using the energy (cold or hot) of the heat pump system 2. Different types of terminal devices exchange heat with the indoor space in different ways.

[0062] There may be one or more terminal groups 31, and more than one terminal group 31 may be distributed in different indoor spaces. The heat exchange types of the terminal groups 31 in different indoor spaces may be the same or different. In one embodiment, different types of terminal devices in the same terminal group 31 are connected in parallel. In other embodiments, different types of terminal devices in the same terminal group 31 may be connected in series.

[0063] The terminal group 31 uses different types of terminal devices in different on / off states in different operating modes. In one embodiment, the operating modes of the terminal group 31 include a first mode and a second mode. The first mode includes all types of terminal devices being turned on, and the second mode includes some types of terminal devices being turned on. In one embodiment, the terminal group 31 includes a first type of terminal device and a second type of terminal device. In the first mode, both the first type of terminal device and the second type of terminal device are turned on. The second mode includes a first sub-mode and / or a second sub-mode. In the first sub-mode, the first type of terminal device is turned on and the second type of terminal device is turned off. In the second sub-mode, the first type of terminal device is turned off and the second type of terminal device is turned on. In other embodiments, the terminal group 31 may also include more than two types of terminal devices; the operating modes of the terminal group may further include a third mode, in which all types of terminal devices are turned off.

[0064] In one embodiment, the terminal group 31 includes radiant terminal devices and convective heat exchange devices. The radiant terminal devices may be underfloor heating coils, radiant panels, capillary networks, radiators, etc., and may be installed on the walls of an indoor space (including walls and / or floors and / or ceilings, etc.). The convective heat exchange devices may include fan coil units, etc. In one embodiment, the first type of terminal equipment is a radiant terminal device, and the second type of terminal equipment is a convective heat exchange device, including the indoor unit in the heat pump system 2.

[0065] In one embodiment, referring to FIG1, the environmental control device includes a heat pump temperature control system 10 and a fresh air system 20. Both the heat pump temperature control system 10 and the fresh air system 20 are connected to the control device 1. The heat pump temperature control system 10 includes a heat pump system 2 and a refrigerant circulation system 3 connected to the heat pump system 2. Both the heat pump system 2 and the refrigerant circulation system 3 are connected to the control device 1.

[0066] In one embodiment, at least two types of terminal devices in the terminal group 31 are respectively disposed in the heat pump system 2 and the refrigerant circulation system 3. The refrigerant circulation system 3 includes a second type of terminal device, and the heat pump system 2 includes a first type of terminal device. For example, the heat pump system 2 may include a convection heat exchange device, which includes an indoor heat exchanger and a corresponding indoor fan, such as a ducted indoor unit; the refrigerant circulation system 3 may include a radiant terminal device.

[0067] The heat pump temperature control system 10 is used to regulate indoor ambient temperature and / or humidity. The fresh air system 20 is used to introduce fresh air and filter and purify it to improve indoor air quality.

[0068] The fresh air system 20 is used to regulate the air in more than one indoor space. In other embodiments, the fresh air system 20 can be used to regulate the air in one indoor space.

[0069] The refrigerant circulation system 3 circulates the refrigerant, delivering the energy output from the heat pump system 2 to the indoor space to regulate its temperature. The heat pump system 2 provides energy (such as cooling or heating) for the heat exchange between the refrigerant circulation system 3 and the indoor space.

[0070] In one embodiment, the refrigerant circulation system 3 is a water system, and the heat pump system 2 is used to regulate the supply water temperature of the refrigerant circulation system 3. The refrigerant circulation system 3 can utilize the terminal assembly 31 to regulate the indoor temperature. In this embodiment, the supply water temperature of the refrigerant circulation system 3 can be understood as the outlet water temperature of the heat pump system 2. In other embodiments, the refrigerant circulation system 3 can also be a system that uses a refrigerant to transfer energy, such as an ethanol solution.

[0071] In one embodiment, the heat pump system 2 is an air source heat pump system 2. In other embodiments, the heat pump system 2 may also be a water source heat pump system, a ground source heat pump system, or a dual-source heat pump system, etc.

[0072] The refrigerant circulation system 3 includes a medium circulation loop and at least one terminal device and a heat exchange module disposed in the medium circulation loop. The heat exchange module is connected to the heat pump system 2 for heat exchange. The medium circulation loop has an inlet and an outlet. The inlet of the medium circulation loop is connected to the outlet of the heat exchange module, and the outlet of the medium circulation loop is connected to the inlet of the heat exchange module. The cooling or heating capacity of the refrigerant in the medium circulation loop can be released into the indoor space where it is located.

[0073] In one embodiment, the heat pump system 2 includes a refrigerant circulation loop, which includes a compressor, a first heat exchanger, a throttling device, and a second heat exchanger. The second heat exchanger is heat-exchange connected to a heat exchange module in the refrigerant circulation system 3. The second heat exchanger and the heat exchange module can be a shell-and-tube heat exchanger or a plate heat exchanger.

[0074] The heat pump system 2 can have two operating modes: cooling mode and heating mode. When the heat pump system 2 is running in cooling mode, the second heat exchanger is in an evaporating state to absorb heat, and when the heat pump system 2 is running in heating mode, the second heat exchanger is in a condensing state to release heat.

[0075] During the operation of heat pump system 2, the water in the heat exchange module absorbs the cold or heat released by the second heat exchanger to form chilled or hot water. The medium carrying the cold or heat flowing out of the heat exchange module can enter the medium circulation loop and flow to the terminal equipment to release the cold or heat into the indoor air, thereby regulating the ambient temperature of the indoor space. After releasing the cold or heat, the medium can re-enter the heat exchange module to exchange heat with the second heat exchanger, and then re-enter the medium circulation loop for heat exchange. This cycle continues, thereby achieving the regulation of the indoor space temperature by the heat pump temperature control system.

[0076] When the heat pump system 2 is running in cooling mode, the second heat exchanger and the terminal equipment in the heat pump system 2 are in an evaporation state. After the medium in the heat exchange module absorbs the cold energy output by the second heat exchanger, its temperature decreases and it forms a medium carrying the cold energy. The medium carrying the cold energy enters the medium circulation loop and flows to the terminal equipment, releasing the cold energy into the indoor space, and the ambient temperature of the indoor space decreases.

[0077] When the heat pump system 2 is in heating mode, the second heat exchanger and the terminal equipment in the heat pump system 2 are in a condensed state. The medium in the heat exchange module absorbs the heat output by the second heat exchanger and its temperature rises to form a heat-carrying medium. The heat-carrying medium enters the medium circulation loop and flows to the terminal equipment, releasing heat into the indoor space, and the ambient temperature of the indoor space rises.

[0078] In other embodiments, the heat pump temperature control system may not have a refrigerant circulation system, the terminal group 31 may be built into the heat pump system 2, or at least two terminal devices in the terminal group 31 may be located in the refrigerant circulation system 3.

[0079] Furthermore, referring to Figure 1, the refrigerant circulation system 3 also includes a fluid regulation module 32. The fluid regulation module 32 is connected to the control device 1 and can be used to regulate the distribution, flow rate regulation, and control of the supply and return liquids in the refrigerant circulation system 3. Specifically, the heat exchange module and the terminal group 31 are both connected to the fluid regulation module 32. In one embodiment, the number of terminal groups 31 is at least two, and both the at least two terminal groups 31 and the heat exchange module are connected to the fluid regulation module 32. The fluid regulation module 32 includes at least two control valves, which are connected one-to-one with the terminal groups 31. In one embodiment, the fluid regulation module is a manifold. In other embodiments, the fluid regulation module 32 can also be a circulation pump.

[0080] In this embodiment, the fresh air system 20 includes a fresh air duct, an exhaust air duct, and a heat pump subsystem. The heat pump subsystem includes a compressor, a third heat exchanger, a throttling device, and a fourth heat exchanger. The third and fourth heat exchangers are respectively connected to the compressor's exhaust port and return port. The third heat exchanger, the throttling device, and the fourth heat exchanger are connected in sequence.

[0081] Fresh air ducts and exhaust air ducts can be equipped with separate fans. When the fan in the fresh air duct is turned on, it can drive fresh outdoor air into the room, and when the fan in the exhaust air duct is turned on, it can drive indoor air out to the outside.

[0082] The third and / or fourth heat exchangers can be installed in the fresh air duct to regulate the temperature and / or humidity of the fresh air.

[0083] One of the third and fourth heat exchangers can be installed in the exhaust duct to recover and utilize the energy in the exhaust air.

[0084] Furthermore, there may be more than one heat pump subsystem, with the third and / or fourth heat exchangers in different heat pump subsystems arranged along the airflow direction in the fresh air duct.

[0085] In other embodiments, the fresh air system 20 may also not include an exhaust duct and / or a heat pump subsystem.

[0086] Furthermore, when the fresh air system 20 is used to regulate more than one indoor space, the fresh air system 20 may also include more than one valve assembly, with each valve assembly corresponding to one indoor space. The valve assembly can be used to regulate the opening and closing of the air duct between the corresponding indoor space and the outdoor environment. When the valve assembly is open, outdoor fresh air can enter the corresponding indoor space, and the air in the corresponding indoor space can be exhausted to the outside; when the valve assembly is closed, outdoor fresh air stops entering the corresponding indoor space, and the air in the corresponding indoor space stops being exhausted to the outside.

[0087] In one embodiment, referring to FIG2, the control device 1 may also be connected to the environmental detection module 5. The environmental detection module 5 may include an indoor sensor and / or an outdoor sensor. The indoor sensor may detect the environmental parameters (temperature, humidity, enthalpy, etc.) of the indoor space regulated by the environmental control equipment; the outdoor temperature sensor may detect the environmental parameters (temperature, humidity, enthalpy, etc.) of the outdoor space where the device is located.

[0088] In one embodiment, referring to FIG2, the control device 1 may also be connected to a temperature sensor 4, which is located on the outlet side of the heat exchange module to detect the outlet temperature of the heat exchange module.

[0089] In this embodiment of the application, referring to FIG2, the control device 1 of the environmental conditioning equipment includes: a processor 1001, such as a CPU, a memory 1002, and a timer 1003. These components are connected and communicate with each other via a communication bus. The memory 1002 can be a high-speed RAM memory or a stable memory (non-volatile memory, NVM), such as a disk storage device. The memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0090] Those skilled in the art will understand that the device structure shown in FIG2 does not constitute a limitation on the device, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0091] As shown in Figure 2, the memory 1002, which serves as a computer storage medium, may include a control program for an environmental control device.

[0092] In the device shown in Figure 2, the processor 1001 can be used to call the control program of the environmental control device stored in the memory 1002 and execute the relevant steps of the control method of the environmental control device in the following embodiments.

[0093] This application also provides a control method for an environmental control device, applied to the aforementioned environmental control device. The environmental control device includes a terminal group, which includes at least two types of terminal devices. In different operating modes, the different types of terminal devices cooperate with each other in different open and closed states.

[0094] Referring to Figure 3, an embodiment of the control method for the environmental conditioning equipment of this application is presented. In one embodiment, the control method for the environmental conditioning equipment includes:

[0095] Step S10: When the environmental conditioning device is in heat exchange mode and operates until a preset condition is met, the first ambient temperature of the indoor space regulated by the terminal group is obtained; wherein, the preset condition indicates that there is a user in the indoor space;

[0096] The heat exchange mode includes either a cooling mode or a heating mode. In one embodiment, the heat exchange mode is a heating mode, in which the terminal device is in a heating state.

[0097] Furthermore, the preset condition indicates that the current time is the initial moment when the user enters the indoor space.

[0098] The environmental control equipment can be considered to meet the preset conditions when it operates under at least one of the following conditions: receiving a user's instruction to enter the indoor space, the current time of the air conditioner reaching the user's set time to enter the indoor space, the presence of human characteristic information in the environmental detection parameters of the indoor space, etc.

[0099] At least two types of terminal devices in the terminal group are located in an indoor space. The initial ambient temperature can be detected in real time by an environmental monitoring module located in the indoor space.

[0100] Step S20: Determine the target operating mode of the terminal group based on the first ambient temperature;

[0101] In one embodiment, in the first and second modes described above, the target operating mode of the terminal group is determined based on a first ambient temperature. In one embodiment, the terminal group includes radiant terminal devices and convective heat exchange devices. The target operating mode includes either the first mode or the second mode. In the first mode, both the radiant terminal devices and the convective heat exchange devices are activated. In the second mode, the radiant terminal devices are activated and the convective heat exchange devices are deactivated. The heat exchange rate of the radiant terminal devices is lower than that of the convective heat exchange devices. The radiant terminal devices can be underfloor heating coils, radiant panels, or radiators; the convective heat exchange devices can be ducted indoor units in a heat pump system, etc.

[0102] In other embodiments, the target operating mode of the terminal group can also be determined based on the first ambient temperature in the first sub-mode and the second sub-mode described above.

[0103] Different initial ambient temperatures correspond to different target operating modes.

[0104] In one embodiment, the target operating mode can be determined based on the temperature range in which the first ambient temperature falls. For example, when the first ambient temperature is in the first temperature range, the first mode is determined as the target operating mode; when the first ambient temperature is in the second temperature range, the second mode is determined as the target operating mode.

[0105] In one embodiment, a relationship value between a first ambient temperature and a reference temperature can be determined, and a target operating mode can be determined based on the numerical range of the relationship value. The reference temperature may include at least one of the following: a preset temperature value, a set temperature of the terminal group (i.e., the target ambient temperature required for the indoor space), the temperature of each terminal device in the terminal group, etc. For example, if the relationship value is in the first numerical range, the first mode is determined as the target operating mode; if the relationship value is in the second numerical range, the second mode is determined as the target operating mode.

[0106] Step S30: Control the terminal group to operate in the target operating mode.

[0107] This application proposes a control method for an environmental control device. The environmental control device includes a terminal group comprising at least two types of terminal devices. When the environmental control device is in heat exchange mode and there are users in the indoor space, the method determines the opening and closing coordination mode between different types of terminal devices based on the ambient temperature of the indoor space regulated by the terminal group. This ensures that when different types of terminal devices are used to exchange heat in the indoor space, the operation of each type of terminal device can be precisely matched with the actual working conditions of the indoor space, guaranteeing coordinated cooperation among the various types of terminal devices. This effectively improves the heat exchange capacity of the environmental control device and enhances the comfort of indoor users.

[0108] In one embodiment, the terminal group is in a heat release state in the heat exchange mode, and the step of determining the target operating mode of the terminal group based on the first ambient temperature includes: when the first ambient temperature meets a first condition, determining a first mode as the target operating mode; and / or when the first ambient temperature does not meet the first condition, determining a second mode as the target operating mode; wherein, the first condition includes at least one of the following: the first ambient temperature is less than a first preset temperature, the temperature difference between the first ambient temperature and the set temperature is less than a first preset temperature difference; in the first mode, at least two types of terminal devices in the terminal group are turned on, and in the second mode, some types of terminal devices among the at least two types of terminal devices are turned on.

[0109] The first condition indicates that the indoor temperature is too low and deviates significantly from the user's comfortable temperature. The temperature difference is calculated by subtracting the set temperature from the first ambient temperature, and the first preset temperature difference is less than 0.

[0110] The set temperature is specifically the target value that the ambient temperature in the indoor space needs to reach.

[0111] In one embodiment, when the first ambient temperature meets the first condition, that is, when the ambient temperature of the indoor space is too low and deviates significantly from the user's comfortable temperature, at least two types of terminal devices are turned on, and different types of terminal devices can be used simultaneously to exchange heat in the indoor space, effectively improving the heat exchange efficiency of the indoor space; when the first ambient temperature does not meet the first condition, that is, when the temperature in the indoor space is not too low, only one type of terminal device is used to exchange heat in the indoor space, thereby effectively avoiding insufficient heat exchange of any type of terminal device when different types of terminal devices are turned on at the same time, ensuring that the temperature difference between the turned-on terminal device and the ambient temperature is large enough to improve the heating capacity of the environmental regulation equipment.

[0112] In one embodiment, the terminal group includes a radiative terminal device and a convective heat exchange device. In the first mode, both the radiative terminal device and the convective heat exchange device are turned on, and in the second mode, the radiative terminal device is turned on and the convective heat exchange device is turned off.

[0113] In one embodiment, when the indoor space temperature is not too low, the radiant terminal device is turned on while the convection heat exchange device is turned off. This can prevent cold air from blowing in when the heat exchange device is insufficient, and can ensure heating of the indoor space in a windless state, which is beneficial to improving the thermal comfort and wind comfort of indoor users. When the indoor space temperature is too low, the radiant terminal device is turned on while the convection heat exchange device is turned off, which is beneficial to improving the heating efficiency of the indoor space.

[0114] Furthermore, based on the above embodiments, another embodiment of the control method for the environmental conditioning device of this application is proposed. In one embodiment, the environmental conditioning device includes at least two terminal groups, and different terminal groups are configured to regulate different indoor spaces. Referring to FIG4, the step of determining the target operating mode of the terminal group based on the first ambient temperature includes:

[0115] Step S200: Determine the target operating mode for each of the terminal groups based on each of the first ambient temperatures;

[0116] In one embodiment, when the first ambient temperature meets the first condition, the target operating mode of the corresponding terminal group is the first mode; when the first ambient temperature does not meet the first condition, the target operating mode of the corresponding terminal group is the second mode.

[0117] The terminal group includes a radiant terminal device and a convective heat exchange device. In the first mode, both the radiant terminal device and the convective heat exchange device are turned on. In the second mode, the radiant terminal device is turned on and the convective heat exchange device is turned off.

[0118] The operating modes of at least two target groups corresponding to at least two end groups can both be the first mode, both be the second mode, or partly the first mode and partly the second mode.

[0119] The step of controlling the terminal group to operate in the target operating mode includes:

[0120] Step S300: Control each of the terminal groups to run in the corresponding target operating mode.

[0121] Specifically, when the target operating mode of the terminal group is the first mode, the terminal group is controlled to operate in the first mode; when the target operating mode of the terminal group is the second mode, the terminal group is controlled to operate in the second mode.

[0122] In one embodiment, the overall comfort of different indoor spaces can be effectively improved by the above method.

[0123] Furthermore, based on any of the above embodiments, another embodiment of the control method for the environmental conditioning equipment of this application is proposed. In one embodiment, the environmental conditioning equipment includes a heat pump system and a refrigerant circulation system. The refrigerant circulation system includes a heat exchange module, which is heat exchanged with the heat pump system. At least two types of terminal devices are respectively installed in the refrigerant circulation system and the heat pump system, or at least two types of terminal devices are both installed in the refrigerant circulation system. Referring to FIG5, the step of determining the target operating mode of the terminal group based on the first ambient temperature further includes:

[0124] Step S201: When the first ambient temperature meets the first condition, the current first liquid outlet temperature of the heat exchange module is detected; the first condition includes at least one of the following: the first ambient temperature is less than the first preset temperature, and the temperature difference between the first ambient temperature and the set temperature is less than the first preset temperature difference.

[0125] The refrigerant flowing out of the heat exchange module flows into different terminal devices.

[0126] The first outlet temperature can be detected by a temperature sensor located on the outlet side of the heat exchange module.

[0127] Step S301: When the first liquid outlet temperature is greater than or equal to the second preset temperature, determine the first mode as the target operating mode; wherein, at least two types of terminal devices in the terminal group corresponding to the first mode are turned on.

[0128] The second preset temperature can be a fixed temperature that has been set in advance, or it can be determined based on the set temperature of the terminal group in each indoor space (that is, the target temperature that the ambient temperature needs to reach) and / or the outdoor ambient temperature, etc.

[0129] In one embodiment, since the heat pump system needs to heat different types of terminal devices simultaneously, when different types of devices in the terminal group need to be turned on simultaneously in a low-temperature environment, the terminal group is controlled to operate in the first mode only when the outlet liquid temperature of the heat exchange module is detected to be higher than a certain threshold. This prevents the heating capacity of the terminal devices from being reduced due to excessively low refrigerant temperature, thereby further improving the heating capacity of the environmental control equipment. When the terminal group includes a convection heat exchange device, the above method can also effectively prevent the convection heat exchange device from blowing cold air towards the user, thereby further improving the user's thermal comfort.

[0130] In one embodiment, after the step of detecting the current first outlet temperature of the heat exchange module, the method further includes: when the first outlet temperature is less than the second preset temperature, controlling the terminal group to operate in a second mode; when the terminal group operates in the second mode until the outlet temperature of the heat exchange module is greater than or equal to the second preset temperature, determining the first mode as the target operating mode; wherein, in the second mode, some types of terminal devices of the at least two types are turned on.

[0131] In one embodiment, in the second mode, the convection heat exchanger is turned off and the radiant terminal device is turned on.

[0132] In one embodiment, by means of the above method, different types of terminal devices are activated simultaneously only when the heat supply of the heat exchange module is sufficiently high. This ensures a sufficiently large temperature difference between the activated terminal devices and the ambient temperature, effectively improving the heat exchange effect between the terminal devices and the indoor space, and further enhancing the heating capacity of the environmental control equipment. In the second mode, the convection heat exchange device is turned off, which helps prevent the convection heat exchange device from blowing cold air towards the user, thereby further improving the user's thermal comfort.

[0133] Furthermore, based on any of the above embodiments, another embodiment of the control method for the environmental control equipment of this application is proposed. In one embodiment, a terminal group with a target mode of a first mode is defined as a first terminal group, and the step of controlling the terminal group to operate in the target operating mode includes: when there are at least two first terminal groups, sequentially controlling at least two first terminal groups to operate in the first mode.

[0134] Here, controlling at least the first terminal group to run in the first mode in sequence means: first, controlling one of the first terminal groups to run in the first mode; when the set conditions are met, the first terminal group currently running in the first mode continues to run in the first mode and controls another first terminal group to run in the first mode, and so on, until all the first terminal groups are running in the first mode.

[0135] The set conditions indicate that when an additional terminal group in the first operating mode is added under the current state, the heat exchange of each terminal group can reach the target heat exchange range.

[0136] The setting conditions may include the required conditions such as the refrigerant temperature in the refrigerant circulation system and / or the running time and / or the environmental conditions of the indoor space regulated by the first terminal group in the first operating mode.

[0137] In one embodiment, the above method helps to further ensure the heating capacity of different first terminal groups for their respective spaces, and further improves the comfort of indoor users.

[0138] In other embodiments, one of the first terminal groups is first controlled to run in the first mode. When the set conditions are met, the first terminal group currently running in the first mode runs in the second mode or shuts down all terminal devices, and another first terminal group is controlled to run in the first mode, and so on, until all the first terminal groups have completed the operation of the first mode.

[0139] In one embodiment, all first terminal groups that are not currently running the first mode are defined as the first terminal set. Referring to FIG6, the step of sequentially controlling at least two first terminal groups to run the first mode includes:

[0140] Step S31: Control the first terminal group in the current first terminal set that meets the second condition to run the first mode;

[0141] Here, the first terminal group that satisfies the second condition can be one or more.

[0142] Step S32: After a first time interval, detect the current second outlet temperature of the heat exchange module;

[0143] The first duration can be a pre-set fixed duration, or it can be a duration determined according to the actual operating conditions of the environmental control equipment. For example, the first duration can be determined based on the second outlet temperature and / or the number of terminal groups currently operating in the first mode.

[0144] Step S33: Determine whether the second outlet temperature is greater than or equal to the second preset temperature;

[0145] When the second outlet temperature is greater than or equal to the second preset temperature, return to step S31 until all the first terminal groups are running the first mode.

[0146] In one embodiment, after a portion of the first terminal group operates in the first mode, the second liquid outlet temperature of the heat exchange module is high enough before another portion of the first terminal group is controlled to operate in the first mode. This ensures that the first terminal groups that are turned on one after the other have sufficient heating capacity, thereby further improving the heating capacity of the environmental control equipment for different indoor spaces and effectively improving the overall comfort of users in each indoor space.

[0147] In one embodiment, the second condition includes a first sub-condition and / or a second sub-condition. The first sub-condition includes the minimum temperature difference between the ambient temperature of the indoor space regulated by the first terminal group and the set temperature, or the lowest ambient temperature of the indoor space regulated by the first terminal group. The second sub-condition includes the maximum rated capacity of the first terminal group.

[0148] The temperature difference is calculated by subtracting the set temperature from the ambient temperature. When the indoor ambient temperature is lower than the set temperature during the heating process of the terminal equipment, the smaller the temperature difference, the lower the temperature of the corresponding space.

[0149] Rated capacity specifically refers to the rated heat exchange capacity of the terminal assembly. In one embodiment, the terminal assembly includes radiant terminal devices and convective heat exchange devices, and the rated capacity refers to the rated power of the fan in the convective heat exchange device.

[0150] In one embodiment, the indoor space with the smallest temperature difference or the lowest room temperature is the coldest, and the first terminal group with the largest rated capacity has the best heating capacity. At this time, the first terminal group of the space will preferentially operate the first mode, which is conducive to the rapid increase of the temperature of the space. On this basis, each first terminal group is controlled to operate the first mode in sequence, which is conducive to improving the overall heating efficiency of multiple spaces, so as to effectively improve the comfort of users in multiple spaces.

[0151] In other embodiments, the second condition may also include a randomly selected first end group, or a first end group with the lowest surface temperature of the radiant end device.

[0152] In one embodiment, the terminal group in the current first terminal set that satisfies the first sub-condition is defined as the second terminal group. The step of controlling the first terminal group in the current first terminal set that satisfies the second condition to run the first mode includes: when the number of the second terminal group is one, controlling the second terminal group to run the first mode; when the number of the second terminal group is more than one, controlling the first terminal group in the current first terminal set that satisfies the second sub-condition to run the first mode.

[0153] In one embodiment, the first terminal group in the indoor space with the lowest room temperature is preferentially controlled to operate in the first mode. If there is more than one first terminal group that meets the first sub-condition, the first terminal group with the largest rated capacity is selected to operate in the first mode, which is beneficial to further improve the overall heating efficiency of each space.

[0154] In one embodiment, the second terminal set is defined as all first terminal groups currently operating in the first mode. Referring to FIG6, after the step of detecting the current second outlet temperature of the heat exchange module, the method further includes:

[0155] When the second outlet temperature is lower than the third preset temperature, step S34 is executed.

[0156] Step S34: Control the first end group in the current second end set that meets the third condition to run the second mode;

[0157] After step S34, return to step S32.

[0158] Wherein, the third preset temperature is less than the second preset temperature, the third condition includes a third sub-condition and / or a fourth sub-condition, the third sub-condition includes the maximum temperature difference between the ambient temperature of the indoor space regulated by the first terminal group and the set temperature or the highest ambient temperature of the indoor space regulated by the first terminal group, and the fourth sub-condition includes the minimum rated capacity of the first terminal group.

[0159] The temperature difference is calculated by subtracting the set temperature from the ambient temperature. If the indoor ambient temperature is less than or equal to the set temperature during the heating process of the terminal equipment, the larger the temperature difference, the higher the temperature of the corresponding space.

[0160] The third preset temperature indicates that the number of first terminal groups in the current first operating mode is too large, resulting in insufficient heat exchange capacity.

[0161] In one embodiment, the terminal assembly includes a radiating terminal device and a convective heat exchange device, and the rated capacity refers to the rated power of the fan in the convective heat exchange device.

[0162] In one embodiment, the indoor space with the largest temperature difference or the highest room temperature is the warmest. When the heat pump system's heating supply is insufficient, controlling the indoor space with the largest temperature difference to operate in the second mode helps to increase the outlet liquid temperature of the heat pump system, thereby increasing the heat exchange capacity of each terminal group and effectively improving the heat exchange capacity of the environmental conditioning equipment. Furthermore, the first terminal group with the smallest rated capacity has the lowest heat exchange efficiency. Therefore, when the heat pump system's heating supply is insufficient, reducing the number of terminal devices activated in this first terminal group helps to increase the heat exchange capacity of each terminal group and simultaneously improve the overall heat exchange efficiency of multiple indoor spaces.

[0163] In other embodiments, when the second outlet temperature is lower than the third preset temperature, the first end group in the current second end set that meets the third condition can also be controlled to stop heat exchange.

[0164] In one embodiment, the terminal group in the current second terminal set that satisfies the third sub-condition is defined as the fourth terminal group. The step of controlling the first terminal group in the current second terminal set that satisfies the third condition to run in the second mode includes: when the number of the fourth terminal group is one, controlling the fourth terminal group to run in the second mode; when the number of the fourth terminal group is more than one, controlling the terminal group in the current second terminal set that satisfies the fourth sub-condition to run in the second mode.

[0165] In one embodiment, when the heat pump system provides insufficient heat, the terminal group with the highest room temperature in the indoor space where the terminal group currently operating in the first mode is located is preferentially controlled to operate in the second mode. If there is more than one terminal group that meets the third sub-condition while currently operating in the first mode, the terminal group with the smallest rated capacity is selected to operate in the second mode, which is beneficial to further improve the overall heating efficiency of each space.

[0166] Furthermore, based on any of the above examples, in one embodiment, the terminal group currently operating in the first mode is defined as the fifth terminal group. In the heat exchange mode, the terminal group is in a heating state. After the step of controlling the terminal group to operate in the target operating mode, the method further includes: when the second ambient temperature of the indoor space regulated by the fifth terminal group meets the fourth condition, controlling the fifth terminal group to operate in the second mode; or, when the duration is greater than or equal to the preset duration, controlling the fifth terminal group to operate in the second mode.

[0167] In the first mode, at least two types of terminal devices in the terminal group are turned on, and in the second mode, some types of terminal devices in the terminal group are turned on. The duration is the time between the initial time and the current time when the terminal group is running in the first mode. The fourth condition includes at least one of the following: the second ambient temperature is greater than the fourth preset temperature; the temperature difference between the second ambient temperature and the set temperature is greater than the second preset temperature difference.

[0168] The fourth condition indicates that the ambient temperature of the corresponding indoor space is high enough to meet the user's comfort.

[0169] When there is more than one fifth terminal group, whether each fifth terminal group switches from the first mode to the second mode is determined by the corresponding second ambient temperature. If the second ambient temperature of the fifth terminal group meets the fourth condition, the corresponding fifth terminal group will run in the second mode; if the second ambient temperature of the fifth terminal group does not meet the fourth condition, the corresponding fifth terminal group will maintain the first mode.

[0170] When the first terminal groups are controlled sequentially to run in the first mode, the initial time here is the start time when the first running first terminal group starts in the first mode. When all first terminal groups start in the first mode simultaneously, the initial time here is the start time of the first mode.

[0171] In one embodiment, after the first terminal group operates in the first mode, it switches to the second mode when the operating time is sufficiently long or the room temperature is sufficiently high. This is beneficial for further increasing the temperature of the terminal devices activated in the second mode, thereby improving the heat exchange efficiency of the terminal devices and further enhancing the heat exchange efficiency of the environmental control equipment. Specifically, in the second mode, when the radiant terminal devices are activated and the convective heat exchange devices are deactivated, the fifth terminal group switches from the first mode to the second mode. This helps prevent hot air from blowing into people, ensuring the temperature comfort of indoor users while improving the airflow comfort of users in the corresponding indoor space.

[0172] Furthermore, this application also proposes a storage medium storing a control program for an environmental control device. When the control program for the environmental control device is executed by a processor, it implements the relevant steps of any of the above embodiments of the control method for the environmental control device.
