[0059] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

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

[0061] This invention provides an environmental control device specifically for regulating the temperature of an indoor environment.

[0062] In this embodiment of the invention, reference is made to Figure 1 and Figure 2 The environmental control equipment includes a heat pump system 2, an energy delivery system 3 connected to the heat pump system 2 for heat exchange, and a control device 1. Both the heat pump system 2 and the energy delivery system 3 are connected to the control device 1. The energy delivery system is used to regulate the temperature of the indoor space using the energy output from the heat pump system. The heat pump system 2 provides energy (such as cooling or heating) for the heat exchange between the energy delivery system 3 and the indoor space.

[0063] In this embodiment, the energy delivery system 3 is a water system, and the heat pump system 2 is used to regulate the water supply temperature of the energy delivery system 3, which in turn regulates the indoor temperature. In this embodiment, the water supply temperature of the energy delivery system 3 can be understood as the outlet water temperature of the heat pump system 2. In other embodiments, the energy delivery system 3 may also be a system that uses other media to transfer energy, such as an ethanol solution.

[0064] In this 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.

[0065] In this embodiment, the heat pump system 2 includes a refrigerant circulation loop and a heat exchange module. The refrigerant circulation loop includes a compressor, a first heat exchanger, a throttling device, and a second heat exchanger. The second heat exchanger is connected to the heat exchange module for heat exchange. The heat pump system 2 can operate in two modes: a cooling mode and a heating mode. When the heat pump system 2 operates in cooling mode, the second heat exchanger is in an evaporating state, absorbing heat. When the heat pump system 2 operates in heating mode, the second heat exchanger is in a condensing state, releasing heat.

[0066] The energy delivery system 3 includes a medium circulation loop and terminal heat exchange devices located within the medium circulation loop. These terminal heat exchange devices may include fan coil units, underfloor heating coils, radiant panels, fan coil units, or radiators. The cooling or heating capacity of the refrigerant (e.g., water, ethylene glycol) in the medium circulation loop can be released into the indoor space where the terminal heat exchange device is located. There may be one or more terminal heat exchange devices, and more than one terminal heat exchange device may be distributed across different indoor spaces. The heat exchange types of the terminal heat exchange devices in different indoor spaces may be the same or different. Therefore, the cooling or heating capacity carried by the refrigerant (e.g., water, ethylene glycol) in the medium circulation loop can be used to regulate the ambient temperature of more than one indoor space. The second heat exchanger and heat exchange module can be a shell-and-tube heat exchanger or a plate heat exchanger.

[0067] 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.

[0068] 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 heat exchange equipment to release the cold or heat into the air of the indoor space to regulate the ambient temperature. 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 enabling the environmental control equipment to regulate the indoor temperature.

[0069] When the heat pump system 2 is running in cooling mode, the second heat exchanger is in an evaporation state. The medium in the heat exchange module absorbs the cold energy output by the second heat exchanger and its temperature decreases to form a medium carrying the cold energy. The medium carrying the cold energy enters the medium circulation loop and flows to the terminal heat exchange equipment, releasing the cold energy into the indoor space, and the ambient temperature of the indoor space decreases.

[0070] When the heat pump system 2 is in heating mode, the second heat exchanger is in a condensing 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 heat exchange equipment, releasing heat into the indoor space and raising the ambient temperature of the indoor space.

[0071] Furthermore, in this embodiment, referring to Figure 2 The control device 1 can also be connected to the environmental detection module 5. The environmental detection module 5 can include an indoor temperature sensor and an outdoor temperature sensor. The indoor temperature sensor can detect the ambient temperature of the indoor space regulated by the environmental control equipment; the outdoor temperature sensor can detect the ambient temperature of the outdoor space where the environmental control equipment is located.

[0072] In this embodiment of the invention, reference is made to Figure 2 The control device 1 of the environmental control equipment includes: a processor 1001 (e.g., CPU), a memory 1002, a timer 1003, etc. The components in the control device 1 are connected via a communication bus. The memory 1002 can be a high-speed RAM or a stable, non-volatile memory, such as a disk drive. Optionally, the memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0073] Those skilled in the art will understand that Figure 2 The device structure shown 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.

[0074] like Figure 2As shown, the memory 1002, which serves as a storage medium, may include a control program for an environmental control device. Figure 2 In the device shown, 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.

[0075] This invention also provides a control method for an environmental control device, which is applied to the aforementioned environmental control device.

[0076] Reference Figure 3 This application proposes an embodiment of a control method for an environmental conditioning device. In this embodiment, the control method for the environmental conditioning device includes:

[0077] Step S10: Obtain the indoor ambient temperature of the indoor space and the outdoor ambient temperature corresponding to the environmental conditioning device;

[0078] Indoor ambient temperature can be detected by an indoor temperature sensor located within the corresponding indoor space. Outdoor ambient temperature can be detected by a separate outdoor temperature sensor, or by a temperature sensor configured on the heat pump system if the heat pump system is located outdoors, or by obtaining local meteorological data from the environmental control equipment via a network.

[0079] Step S20: Determine the target heat exchange mode of the environmental conditioning device based on the indoor ambient temperature, the set temperature corresponding to the indoor space, and the outdoor ambient temperature.

[0080] The set temperature is specifically the target value that the indoor space's ambient temperature needs to reach under the pre-set environmental control equipment.

[0081] The target heat exchange mode is the heat exchange mode required for the specific environmental control equipment to operate. Specifically, it can be determined as the target heat exchange mode based on the indoor ambient temperature, the set temperature, and the outdoor ambient temperature, either in cooling mode or heating mode.

[0082] Different indoor ambient temperatures, set temperatures, and outdoor ambient temperatures correspond to different target heat exchange modes. The correspondence between indoor ambient temperature, set temperature, outdoor ambient temperature and target heat exchange mode can be established in advance. Based on this correspondence, the target heat exchange mode corresponding to the current indoor ambient temperature, set temperature and outdoor ambient temperature can be determined.

[0083] Specifically, a first temperature difference between the indoor ambient temperature and the set temperature is determined. If the first temperature difference is outside a first preset temperature difference range, the target heat exchange mode is determined based on the first temperature difference. If the first temperature difference is within the first preset temperature difference range and the target heat exchange mode cannot be determined based on the first temperature difference, the target heat exchange mode is then determined based on the outdoor ambient temperature. Alternatively, if the outdoor ambient temperature or a characteristic temperature determined by the outdoor ambient temperature and other temperatures is outside a second preset temperature difference range, the target heat exchange mode is determined based on the outdoor ambient temperature or the characteristic temperature. If the characteristic temperature is within the second preset temperature difference range and the target heat exchange mode cannot be determined based on the outdoor ambient temperature or the characteristic temperature, the target heat exchange mode is then further determined based on the first temperature difference.

[0084] When the environmental control equipment regulates more than one indoor space, it can obtain the indoor ambient temperature of more than one indoor space, and determine the target heat exchange mode of the environmental control equipment based on the indoor ambient temperature of more than one indoor space, the corresponding set temperature, and the outdoor ambient temperature.

[0085] Specifically, step S10 can be executed during the operation of the heat exchange mode of the environmental control equipment. The target heat exchange mode can be the same as or different from the heat exchange mode currently being operated by the environmental control equipment.

[0086] Step S30: Control the environmental conditioning equipment to operate the target heat exchange mode.

[0087] When the target heat exchange mode is cooling mode, the environmental control equipment can be controlled to operate in cooling mode.

[0088] When the target heat exchange mode is heating mode, the environmental control equipment can be controlled to operate in heating mode.

[0089] This invention proposes a control method for an environmental conditioning device. Based on the environmental conditioning device equipped with a heat pump system and an energy transmission system connected to the heat pump system, the method determines the target heat exchange mode of the device by adjusting the indoor ambient temperature, the set temperature, and the outdoor ambient temperature of the indoor space. This enables the environmental conditioning device to automatically select a suitable operating mode, allowing it to operate in a heat exchange mode that meets the user's comfort needs without user intervention. This simplifies user operation, improves the intelligence level of the environmental conditioning device, and enhances the user experience.

[0090] Furthermore, after step S30, the process can return to step S10 at set intervals. Based on this, the heat exchange mode of the environmental control equipment can be adaptively adjusted to the changes in heat exchange demand under the current environmental changes during the start-up process, thereby further improving the intelligence level of the environmental control equipment operation.

[0091] Furthermore, based on the above embodiments, another embodiment of the control method for the environmental conditioning equipment of this application is proposed. In this embodiment, reference is made to... Figure 4 Step S20 includes:

[0092] Step S21: Determine the target heat exchange mode based on the first temperature difference between the indoor ambient temperature and the set temperature and the outdoor ambient temperature.

[0093] In this embodiment, the first temperature difference value is the calculated result obtained by subtracting the set temperature from the indoor ambient temperature.

[0094] Specifically, different first temperature difference values ​​and different outdoor ambient temperatures correspond to different target heat exchange modes. A first interval containing the first temperature difference value and a second interval containing the outdoor ambient temperature can be determined, and the heat exchange mode matching the first interval and the second interval can be used as the target heat exchange mode. Alternatively, the characteristic value of the heat exchange mode can be calculated using the first temperature difference value and the outdoor ambient temperature, and the heat exchange mode associated with the numerical interval containing the characteristic value can be used as the target heat exchange mode.

[0095] Furthermore, in this embodiment, step S21 includes:

[0096] When the outdoor ambient temperature is greater than or equal to the first preset temperature, the cooling mode is determined to be the target heat exchange mode;

[0097] When the outdoor ambient temperature is lower than the second preset temperature, the heating mode is determined to be the target heat exchange mode;

[0098] When the outdoor ambient temperature is greater than or equal to the second preset temperature and the outdoor ambient temperature is less than the first preset temperature, the target heat exchange mode is determined according to the first temperature difference value; wherein, the first preset temperature is greater than the second preset temperature.

[0099] In this embodiment, the temperature difference between the indoor ambient temperature and the set temperature accurately characterizes the heat exchange demand of the indoor space. Furthermore, by combining this with the outdoor ambient temperature, the heat exchange demand of the environmental control equipment under the current environment can be accurately reflected. Based on this, the target heat exchange mode is determined by combining the first temperature difference value and the outdoor ambient temperature, ensuring that the heat exchange operation of the environmental control equipment can accurately meet the user's heat exchange demand under the current environment. The outdoor ambient temperature accurately reflects the changing trend of indoor heat exchange demand. Therefore, determining the target heat exchange mode first based on the outdoor ambient temperature, and then further determining the target heat exchange mode by combining the temperature difference between the indoor ambient temperature and the set temperature when the outdoor ambient temperature cannot be determined, helps ensure that the environmental control equipment can timely and accurately meet the indoor user's heat exchange demand.

[0100] 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 this embodiment, reference is made to... Figure 5 Step S20 includes:

[0101] Step S22: Determine the target heat exchange mode based on the first temperature difference between the indoor ambient temperature and the set temperature, and the second temperature difference between the outdoor ambient temperature and the set temperature;

[0102] In this embodiment, the first temperature difference is the calculated result of subtracting the set temperature from the indoor ambient temperature. The second temperature difference is the calculated result of subtracting the set temperature from the outdoor ambient temperature. When there are more than one set temperature corresponding to an indoor space, a reference set temperature can be determined based on these multiple set temperatures, and the second temperature difference is the calculated result of subtracting the reference set temperature from the outdoor ambient temperature. Specifically, the average of the multiple set temperatures can be used as the reference set temperature.

[0103] Specifically, different first temperature difference values ​​and different second temperature difference values ​​correspond to different target heat exchange modes. A first interval containing the first temperature difference value and a third interval containing the second temperature difference value can be determined, and the heat exchange mode matching the first interval and the third interval can be used as the target heat exchange mode. Alternatively, the characteristic value of the heat exchange mode can be calculated using the first temperature difference value and the second temperature difference value, and the heat exchange mode associated with the numerical interval containing the characteristic value can be used as the target heat exchange mode.

[0104] Furthermore, in this embodiment, step S22 includes:

[0105] When the second temperature difference is greater than or equal to the first preset temperature difference, the cooling mode is determined to be the target heat exchange mode;

[0106] When the second temperature difference is less than the second preset temperature difference, the heating mode is determined to be the target heat exchange mode;

[0107] When the second temperature difference value is greater than or equal to the second preset temperature difference and the second temperature difference value is less than the first preset temperature difference, the target heat exchange mode is determined according to the first temperature difference value.

[0108] Wherein, the first preset temperature difference is greater than the second preset temperature difference.

[0109] In this embodiment, the temperature difference between the indoor ambient temperature and the set temperature, combined with the temperature difference between the outdoor ambient temperature and the set temperature, accurately reflects the heat exchange requirements of the environmental control equipment under the current environment. Based on this, the target heat exchange mode is determined by combining the first temperature difference value and the second temperature difference value, ensuring that the heat exchange operation of the environmental control equipment can accurately meet the user's heat exchange requirements under the current environment. The second temperature difference value accurately reflects the changing trend of indoor heat exchange requirements. Therefore, determining the target heat exchange mode first based on the second temperature difference value, and then further combining the first temperature difference value between the indoor ambient temperature and the set temperature when the second temperature difference value cannot be determined, helps ensure that the environmental control equipment can timely and accurately meet the indoor user's heat exchange requirements.

[0110] 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 this embodiment, reference is made to... Figure 6 Step S20 includes:

[0111] Step S23: Determine the target heat exchange mode based on the first temperature difference between the indoor ambient temperature and the set temperature, and the third temperature difference between the outdoor ambient temperature and the indoor ambient temperature.

[0112] In this embodiment, the first temperature difference is the calculated result of subtracting the set temperature from the indoor ambient temperature. The third temperature difference is the calculated result of subtracting the indoor ambient temperature from the outdoor ambient temperature. When there are more than one indoor space with corresponding indoor ambient temperatures, a reference indoor temperature can be determined based on these multiple indoor ambient temperatures, and the third temperature difference is the calculated result of subtracting the reference indoor temperature from the outdoor ambient temperature. Specifically, the average of the multiple indoor ambient temperatures can be used as the reference indoor temperature.

[0113] Specifically, different first temperature difference values ​​and different third temperature difference values ​​correspond to different target heat exchange modes. The first interval containing the first temperature difference value and the fourth interval containing the second temperature difference value can be determined, and the heat exchange mode matching the first interval and the fourth interval can be used as the target heat exchange mode. Alternatively, the characteristic value of the heat exchange mode can be calculated using the first temperature difference value and the third temperature difference value, and the heat exchange mode associated with the numerical interval containing the characteristic value can be used as the target heat exchange mode.

[0114] Furthermore, in this embodiment, step S23 includes:

[0115] When the third temperature difference value is greater than or equal to the third preset temperature difference, the cooling mode is determined to be the target heat exchange mode;

[0116] When the third temperature difference value is less than the fourth preset temperature difference, the heating mode is determined to be the target heat exchange mode;

[0117] When the third temperature difference value is greater than or equal to the fourth preset temperature difference, and the second temperature difference value is less than the third preset temperature difference, the target heat exchange mode is determined based on the first temperature difference value.

[0118] The third preset temperature difference is greater than the fourth preset temperature difference.

[0119] In this embodiment, the temperature difference between the indoor ambient temperature and the set temperature, combined with the temperature difference between the outdoor ambient temperature and the indoor ambient temperature, accurately reflects the heat exchange requirements of the environmental control equipment under the current environment. Based on this, the target heat exchange mode is determined by combining the first temperature difference value and the third temperature difference value, ensuring that the heat exchange operation of the environmental control equipment can accurately meet the user's heat exchange requirements under the current environment. The third temperature difference value accurately reflects the changing trend of indoor heat exchange requirements. Therefore, determining the target heat exchange mode first based on the third temperature difference value, and then further combining the first temperature difference value between the indoor ambient temperature and the set temperature when the third temperature difference value cannot be determined, helps ensure that the environmental control equipment can timely and accurately meet the indoor user's heat exchange requirements.

[0120] Furthermore, the three embodiments described above provide three methods for determining the target heat exchange mode. In practical applications, any one of the three methods can be used to determine the target heat exchange mode, or any combination of two of the three methods can be used, or all of the three methods can be used. Specifically, the target heat exchange mode can be determined based on a first temperature difference value, an outdoor ambient temperature, and a second temperature difference value. Alternatively, the target heat exchange mode can be determined based on a first temperature difference value, a second temperature difference value, and a third temperature difference value. Or, the target heat exchange mode can be determined based on a first temperature difference value, an outdoor ambient temperature, a second temperature difference value, and a third temperature difference value, and so on.

[0121] 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 this embodiment, the number of indoor ambient temperatures is more than one, the number of indoor spaces is more than one, and different indoor ambient temperatures correspond to different indoor spaces, as shown in the reference. Figure 7 The step of determining the target heat exchange mode based on the first temperature difference value includes:

[0122] Step S201: Determine the corresponding heat exchange requirement based on the first temperature difference value of each indoor space to obtain more than one heat exchange requirement;

[0123] Specifically, the temperature difference range containing the first temperature difference value can be determined, and the heat exchange requirement can be determined based on the temperature difference range. The heat exchange requirement includes either cooling requirement or heating requirement.

[0124] Specifically, when the first temperature difference is greater than or equal to the fifth preset temperature difference, the heat exchange demand of the indoor space is determined to be a cooling demand; when the first temperature difference is less than the sixth preset temperature difference, the heat exchange demand of the indoor space is determined to be a heating demand; when the first temperature difference is less than the fifth preset temperature difference and greater than or equal to the sixth preset temperature difference, the corresponding heat exchange demand is determined to be no cooling demand and no heating demand; wherein, the fifth preset temperature difference is greater than the sixth preset temperature difference.

[0125] Step S202: Determine the target heat exchange mode based on the first quantity of cooling demand and the second quantity of heating demand among all the heat exchange demands.

[0126] In this embodiment, when the first quantity is greater than the second quantity, the cooling mode is determined as the target heat exchange mode; when the second quantity is greater than the first quantity, the heating mode is determined as the target heat exchange mode; when the first quantity is equal to the second quantity, the heat exchange mode currently operating on the environmental control device is determined as the target heat exchange mode. When the first quantity is equal to the second quantity, if the environmental control device is currently operating in cooling mode, then the cooling mode is determined as the target heat exchange mode; if the environmental control device is currently operating in heating mode, then the heating mode is determined as the target heat exchange mode.

[0127] In other embodiments, when the first quantity equals the second quantity, a fixed mode preset in the cooling mode and heating mode may be used as the target heat exchange mode. Alternatively, when the first quantity equals the second quantity, a first average of the absolute values ​​of all first temperature differences corresponding to all indoor spaces with cooling needs is determined, and a second average of the absolute values ​​of all first temperature differences corresponding to all indoor spaces with heating needs is determined. If the first average is greater than the second average, the cooling mode is determined as the target heat exchange mode; if the first average is less than the second average, the heating mode is determined as the target heat exchange mode.

[0128] Based on this, it can be ensured that the operation of environmental control equipment can be precisely matched with the temperature comfort needs of most indoor users, thereby improving the overall comfort of users in more than one indoor space.

[0129] In other embodiments, when there is only one indoor space, the target heat exchange mode can be determined directly based on the temperature difference range where the first temperature difference value is located. Different temperature difference ranges correspond to different target heat exchange modes. Specifically, when the first temperature difference value is greater than or equal to the fifth preset temperature difference, the cooling mode is determined as the target heat exchange mode; when the first temperature difference value is less than the sixth preset temperature difference, the heating mode is determined as the target heat exchange mode.

[0130] In other embodiments, when there is more than one indoor space, a characterization temperature representing the indoor heat exchange demand can be determined based on the temperature of more than one indoor environment. For example, the average, maximum, or minimum value of more than one indoor environment temperature can be used as the characterization temperature, and the operating mode can be determined according to the range of the characterization temperature. For example, if the characterization temperature is less than a seventh preset temperature, the cooling mode is determined as the operating mode; if the characterization temperature is greater than or equal to an eighth preset temperature, the heating mode is determined as the operating mode, where the seventh preset temperature is less than or equal to the eighth preset temperature.

[0131] Furthermore, based on any of the above embodiments, yet another embodiment of the control method for the environmental conditioning equipment of this application is proposed. In this embodiment, the energy delivery system includes more than one terminal heat exchange device, and different terminal heat exchange devices are used to regulate the temperature of different indoor spaces. Based on this, step S20 includes:

[0132] Obtain the current percentage of the terminal heat exchanger that is in the active state among all the terminal heat exchangers;

[0133] When the current proportion is greater than the first preset proportion, the step of determining the target heat exchange mode based on the first temperature difference between the indoor ambient temperature and the set temperature and the outdoor ambient temperature is executed.

[0134] When the current percentage is less than or equal to the first preset percentage and the current percentage is greater than the second preset percentage, the process of determining the target heat exchange mode based on the first temperature difference between the indoor ambient temperature and the set temperature, and the third temperature difference between the outdoor ambient temperature and the indoor ambient temperature is executed.

[0135] When the current proportion is less than or equal to the second preset proportion, the step of determining the target heat exchange mode based on the first temperature difference between the indoor ambient temperature and the set temperature, and the second temperature difference between the outdoor ambient temperature and the set temperature is executed;

[0136] Wherein, the first preset proportion is greater than the second preset proportion.

[0137] The first and second preset ratios can be fixed parameters that have been set in advance, or parameters that can be determined based on the actual operating conditions of the environmental control equipment.

[0138] In this embodiment, the target heat exchange mode is determined based on the current percentage of activated terminal heat exchange devices among all terminal heat exchange devices in the environmental control equipment. When the percentage of activated terminal heat exchange devices is large (i.e., greater than a first preset percentage), it indicates that most users in more than one indoor space currently have heat exchange needs. In this case, determining the target heat exchange mode by combining the first temperature difference value and the outdoor ambient temperature is beneficial for ensuring that the operation of the environmental control equipment can adapt to the changing trend of the overall heat exchange needs of more than one indoor space, and further ensuring the actual comfort needs of each indoor space. This reduces the need for frequent switching of heat exchange modes in more than one space while meeting the comfort needs of users in each space. When the percentage of activated terminal heat exchange devices is small (i.e., less than or equal to a second preset percentage), it indicates that a small number of users in more than one indoor space currently have heat exchange needs, and the outdoor ambient temperature can generally meet the comfort needs of the indoor users. In this case, determining the target heat exchange mode by combining the first temperature difference value and the second temperature difference value is beneficial for effectively improving the accuracy of the heat exchange mode adjustment of the environmental control equipment, so as to ensure the precise satisfaction of the comfort needs of the small number of indoor users. When the proportion of activated terminal heat exchange devices is moderate (that is, greater than the second preset proportion and rain or equal to the first preset proportion), it indicates that the number of spaces with heat exchange needs and spaces without heat exchange needs is roughly equal in more than one indoor space. At this time, combining the first temperature difference value and the third temperature difference value to determine the target heat exchange mode is beneficial to accurately characterize the impact of changes in outdoor ambient temperature on changes in indoor heat exchange needs, and ensure that even if the outdoor ambient temperature changes rapidly, the environmental control equipment can respond quickly to meet the comfort needs of indoor users.

[0139] Furthermore, based on any of the above embodiments, the number of indoor spaces is more than one, and the capacity delivery system includes terminal heat exchange devices disposed in each of the indoor spaces. Based on this, a corresponding weight value can be determined according to the heat exchange type of the terminal heat exchange device in each indoor space. The weighted average of the set temperatures corresponding to all the indoor spaces, based on the weight value of each indoor space, is used as a reference set temperature. The temperature difference between the outdoor ambient temperature and the reference set temperature is then determined as the second temperature difference value mentioned above. The weighted average of the indoor ambient temperatures, based on the weight value of each indoor space, is used as a reference indoor temperature. The temperature difference between the outdoor ambient temperature and the reference set temperature is then determined as the third temperature difference value mentioned above.

[0140] Furthermore, based on any of the above embodiments, the operation mode determination operation is defined to include the above steps S10 and S20. Based on this, the operation mode determination operation is executed to obtain a first target heat exchange mode; after a target time interval, the operation mode determination operation is executed to obtain a second target heat exchange mode; when the first target heat exchange mode and the second target heat exchange mode are the same, step S30 is executed; when the first target heat exchange mode and the second target heat exchange mode are different, the environmental conditioning device is controlled to maintain the current heat exchange mode operation.

[0141] Furthermore, in this embodiment, the current user setting parameters of the preset function of the radiant air conditioner are obtained. When the user setting parameters indicate that the preset function is enabled, an operation mode determination operation is performed to obtain a first target heat exchange mode. After a target time interval, an operation mode determination operation is performed again to obtain a second target heat exchange mode. When the first target heat exchange mode and the second target heat exchange mode are the same, step S30 is executed. When the first target heat exchange mode and the second target heat exchange mode are different, the environmental conditioning equipment is controlled to maintain the current heat exchange mode, thereby realizing the automatic switching of the heat exchange mode of the environmental conditioning equipment. In other embodiments, the operation mode can also be switched according to user input commands.

[0142] The target duration here can be a pre-set fixed duration, a duration determined based on the actual operating status of the environmental control equipment, a duration determined based on the equipment characteristic parameters of the environmental control equipment, or a duration determined based on the actual operating status of the environmental control equipment and the equipment characteristic parameters of the environmental control equipment (such as the heat exchange type of the terminal heat exchange equipment).

[0143] Based on this, instead of directly using the first target heat exchange mode after determining the first target heat exchange mode, the second target heat exchange mode, determined in conjunction with the target duration, is used to determine the target heat exchange mode for the operation of the heat pump system. This helps ensure that the operating mode of the heat pump system can be set to adapt to changes in ambient temperature before and after the target duration, accurately matching user needs. It also ensures that the heat pump system can automatically operate according to the user's required mode while simplifying user operation. As a result, the environmental control equipment can automatically select the appropriate operating mode, improving the intelligence level of the environmental control equipment and enhancing the user experience.

[0144] In particular, when the first target heat exchange mode and the second target heat exchange mode are different, the heat pump system maintains the current heat exchange mode, which helps to avoid frequent switching of heat exchange modes and also avoids inaccurate switching that reduces user comfort, thereby further improving the user experience.

[0145] Furthermore, the control methods for environmental control equipment also include:

[0146] Step S01: Obtain the heat exchange type of the terminal heat exchange device;

[0147] The heat exchange type specifically represents the form of heat exchange between the terminal heat exchange equipment and the indoor space it is located in.

[0148] In this embodiment, the heat exchange type includes convective heat exchange and / or radiative heat exchange. Specifically, in the case of a terminal heat exchange device using convective heat exchange, an indoor fan is activated, driving air in the indoor space to flow through the terminal heat exchange device and absorb the cold or heat energy of the medium flowing through it. In the case of a terminal heat exchange device using radiative heat exchange, energy is transferred between the terminal heat exchange device and the indoor air through thermal radiation.

[0149] When there is more than one terminal heat exchanger, the heat exchange type of all terminal heat exchangers or the heat exchange type of the currently active terminal heat exchanger can be obtained.

[0150] The heat exchange type of the terminal heat exchanger can be obtained by reading pre-stored parameters or by acquiring user-input settings. Alternatively, the environmental control equipment can be controlled to operate at preset parameters under a preset ambient temperature, and the temperature change parameters of the terminal heat exchanger can be acquired. The heat exchange type of the corresponding terminal heat exchanger can then be determined based on these temperature change parameters.

[0151] Step S02: Determine the target duration based on the heat exchange type.

[0152] Different heat exchange types correspond to different target durations. Specifically, the correspondence between heat exchange types and target durations can be preset, and can be a mapping relationship or a calculation relationship, etc. Based on this correspondence, the target duration corresponding to the current heat exchange type can be determined. When the correspondence is a calculation relationship, different heat exchange types can be represented by different characterization values, and the target duration can be calculated by substituting the characterization value corresponding to the current heat exchange type into the calculation relationship.

[0153] In this embodiment, when the heat exchange type is convective heat exchange, a first duration is determined as the target duration; when the heat exchange type is radiative heat exchange, a second duration is determined as the target duration; when the heat exchange type includes both convective and radiative heat exchange, a third duration is determined as the target duration. The first duration may be longer than the third duration, and the third duration may be longer than the second duration.

[0154] In this embodiment, since the heat exchange efficiency of terminal heat exchange devices of different heat exchange types is different, the heat exchange type of the terminal heat exchange device is determined accordingly. Based on this, it is beneficial to ensure that the environmental control equipment can quickly reach the environmental state that meets the user's comfort needs after switching operating modes.

[0155] Furthermore, this invention 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.
