[0026] When the number of cooling demands out of all heat exchange demands exceeds the number of heating demands, the cooling mode is determined as the operating mode.

[0027] When the number of heating demands out of all heat exchange demands exceeds the number of cooling demands, the heating mode is determined to be the operating mode.

The heat pump system is then controlled to operate according to the determined target operating mode. Based on this, instead of directly operating according to the first operating mode after determining the first operating mode, the method combines the second operating mode determined after the target duration to determine the target operating mode of the heat pump system. This helps ensure that the operating mode of the heat pump system can be adapted to changes in ambient temperature before and after the target duration, accurately matching user needs. It ensures that the heat pump system can automatically operate according to the user's desired mode while simplifying user operation. This allows the environmental conditioning device to automatically select an appropriate operating mode, improving the intelligence of the environmental conditioning device and enhancing the user experience.

[0052] 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

[0053] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0054] This invention provides an environmental control device specifically for regulating the temperature of an indoor environment.

[0055] 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, 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 heat exchange between the energy delivery system 3 and the indoor space.

[0056] 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.

[0057] 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.

[0058] In this embodiment, the heat pump system 2 includes a refrigerant circulation loop, which comprises a compressor, a first heat exchanger, a throttling device, and a second heat exchanger. The second heat exchanger is connected to the energy transfer system 3 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.

[0059] The energy transfer system 3 includes a medium circulation loop and terminal heat exchange devices and heat exchange modules located within the medium circulation loop. The heat exchange modules are connected to a second heat exchanger for heat exchange. The terminal heat exchange devices may include fan coil units, underfloor heating coils, radiant panels, fan coil units, or radiator fins, etc. The cold or heat energy of the water 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 in different indoor spaces. The heat exchange types of the terminal heat exchange devices in different indoor spaces may be the same or different. Based on this, the cold or heat energy carried by the medium 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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 / or 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.

[0065] 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.

[0066] 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.

[0067] like Figure 2 As 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.

[0068] This invention also provides a control method for an environmental control device, which is applied to the aforementioned environmental control device.

[0069] 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:

[0070] Step S10: Perform an operation mode determination operation to obtain a first operation mode. The operation mode determination operation includes: obtaining the ambient temperature corresponding to the environmental conditioning device and determining the operation mode of the heat pump system based on the ambient temperature.

[0071] The ambient temperature here can include indoor and / or outdoor ambient temperatures. Different ambient temperatures correspond to different operating modes.

[0072] The operating mode determined based on the current ambient temperature will be used as the first operating mode.

[0073] The first operating mode here may include one of a cooling mode and a heating mode. In other embodiments, the first operating mode may also include other modes such as a defrosting mode.

[0074] Specifically, step S10 is performed when the environmental control equipment is turned on.

[0075] Step S20: At intervals of the target duration, perform the operation to determine the operating mode and obtain the second operating mode;

[0076] 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).

[0077] The operating mode determined based on the current ambient temperature will be used as the second operating mode.

[0078] The second operating mode here may include one of a cooling mode and a heating mode. In other embodiments, the second operating mode may also include other modes such as a defrosting mode.

[0079] Furthermore, step S20 can be executed when the first operating mode is different from the current operating mode of the heat pump system.

[0080] Step S30: Determine the target operating mode of the heat pump system based on the first operating mode and the second operating mode;

[0081] Different first operating modes and different second operating modes correspond to different target operating modes.

[0082] In this embodiment, when both the first operating mode and the second operating mode are cooling modes, the cooling mode is determined as the target operating mode; when both the first operating mode and the second operating mode are heating modes, the heating mode is determined as the target operating mode; when the first operating mode and the second operating mode are different operating modes, the current operating mode of the heat pump system is determined as the target operating mode. Specifically, when the first operating mode and the second operating mode are different operating modes, the target operating mode is heating mode when the current operating mode of the heat pump system is heating mode; and the target operating mode is cooling mode when the current operating mode of the heat pump system is cooling mode.

[0083] Step S40: Control the operation of the heat pump system according to the target operating mode.

[0084] Specifically, when the target operating mode is cooling mode, the heat pump system is controlled to operate in cooling mode. At this time, the heat pump system outputs cooling capacity to the energy transmission system, and the energy transmission system releases cooling capacity into the indoor space. When the target operating mode is heating mode, the heat pump system is controlled to operate in heating mode. At this time, the heat pump outputs heat capacity to the energy transmission system, and the energy transmission system releases heat into the indoor space.

[0085] This invention proposes a control method for an environmental conditioning device. Based on an environmental conditioning device equipped with a heat pump system and an energy transmission system connected to the heat pump system, this method determines the target operating mode of the heat pump system twice, using a target duration as the interval between two operating modes determined by the ambient temperature. The method then controls the heat pump system to operate according to the determined target operating mode. Based on this, instead of directly operating according to the first operating mode after determining the first operating mode, the method combines the first operating mode with a second operating mode determined after the target duration to determine the target operating mode of the heat pump system. This helps ensure that the operating mode of the heat pump system can be adapted to changes in ambient temperature before and after the target duration, accurately matching user needs. It ensures that the heat pump system can automatically operate according to the user's desired mode while simplifying user operation. This allows the environmental conditioning device to automatically select an appropriate operating mode, improving the intelligence of the environmental conditioning device and enhancing the user experience.

[0086] In particular, when the first operating mode and the second operating mode are different, the heat pump system maintains the current operating mode, which helps to avoid frequent switching of operating modes and also avoids inaccurate switching that reduces user comfort, thereby further improving the user experience.

[0087] Furthermore, in this embodiment, after step S40, the method further includes: when the first operating mode and the second operating mode are different operating modes, setting the second operating mode as a new first operating mode; returning to the execution of the target interval duration, performing the operating mode determination operation, and obtaining the second operating mode.

[0088] Based on this, when the operating modes determined in two consecutive determinations are different, the operating mode can be further determined at the target interval to further confirm whether the operating mode needs to be switched. This avoids frequent switching of operating modes while ensuring the accuracy of the heat pump system's operating mode and further improves the user experience.

[0089] 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, the energy transmission system includes a terminal heat exchange device, referring to... Figure 4 Before step S20, the procedure further includes:

[0090] Step S01: Obtain the heat exchange type of the terminal heat exchange device;

[0091] 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.

[0092] 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.

[0093] When there is more than one terminal heat exchanger, the heat exchange type of all terminal heat exchangers can be obtained, or the heat exchange type of the currently activated terminal heat exchanger can be obtained.

[0094] The heat exchange type of the terminal heat exchanger can be obtained by reading pre-stored parameters or by acquiring user-inputted 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.

[0095] Step S02: Determine the target duration based on the heat exchange type.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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 ambient temperature includes outdoor ambient temperature and / or indoor ambient temperature. When there is more than one indoor space, the indoor ambient temperature of all indoor spaces can be acquired, or the indoor ambient temperature of the indoor space where the terminal heat exchanger is activated can be acquired, or the indoor ambient temperature of a specific space within all indoor spaces can be acquired. The indoor ambient temperature can be detected by an indoor temperature sensor in the corresponding indoor space. The outdoor ambient temperature can be detected by a separately installed outdoor temperature sensor, or, if the heat pump system is located outdoors, by a temperature sensor configured on the heat pump system, or by obtaining local meteorological data from the network.

[0100] The step of determining the operating mode of the heat pump system based on the ambient temperature includes: determining the operating mode based on the indoor ambient temperature and / or the outdoor ambient temperature.

[0101] In this embodiment, the operating mode is determined based on both the indoor and outdoor ambient temperatures. In other embodiments, the operating mode may also be determined based on either the indoor or outdoor ambient temperatures.

[0102] In this embodiment, refer to Figure 5 The step of determining the operating mode based on the indoor ambient temperature and / or the outdoor ambient temperature includes:

[0103] Step S100: When the outdoor ambient temperature is greater than or equal to the first preset temperature, the cooling mode is determined to be the operating mode.

[0104] The first preset temperature is specifically the highest temperature value that is allowed under the user's comfort state, as preset. The first preset temperature can be a fixed temperature set in advance, or it can be a temperature determined by obtaining user instructions. When the outdoor ambient temperature is greater than or equal to the first preset temperature, it indicates that the indoor user is likely to feel uncomfortable due to overheating under this state. At this time, it can be assumed that the user has a cooling need, and the cooling mode will be used as the operating mode.

[0105] Step S200: When the outdoor ambient temperature is lower than the second preset temperature, the heating mode is determined to be the operating mode.

[0106] The second preset temperature is specifically the lowest acceptable temperature value for the user's comfort state, set in advance. The second preset temperature can be a fixed pre-set temperature or a temperature determined by receiving user commands. When the outdoor ambient temperature is lower than the second preset temperature, it indicates that the indoor user is likely to feel uncomfortable due to excessive cold in this state. In this case, it can be assumed that the user has a heating need, and the heating mode will be used as the operating mode.

[0107] Step S300: When the outdoor ambient temperature is greater than or equal to the second preset temperature and less than the first preset temperature, the operating mode is determined according to the indoor ambient temperature; wherein, the first preset temperature is greater than the second preset temperature.

[0108] When the outdoor ambient temperature is greater than or equal to the second preset temperature and less than the first preset temperature, it is not possible to accurately identify the indoor user's demand for the operation mode of the environmental control equipment by means of the outdoor ambient temperature. Therefore, the operation mode is determined by means of the indoor ambient temperature.

[0109] Different indoor ambient temperatures correspond to different operating modes. Specifically, a correspondence between indoor ambient temperature and operating mode can be established in advance, and the operating mode corresponding to the current indoor ambient temperature can be determined based on this correspondence.

[0110] In this embodiment, the environmental control device regulates more than one indoor space, acquiring the indoor temperature of each space to obtain more than one indoor ambient temperature. Different indoor ambient temperatures correspond to different indoor spaces regulated by the environmental control device. Based on this, the process of determining the operating mode according to the indoor ambient temperature is as follows: The heat exchange demand of the corresponding indoor space is determined based on each indoor ambient temperature; when the number of cooling demands outnumbers the number of heating demands, the cooling mode is determined as the operating mode; when the number of heating demands outnumbers the number of cooling demands, the heating mode is determined as the operating mode; when the number of heating demands and cooling demands are equal, the current heat exchange mode of the environmental control device is determined as the operating mode. This ensures that the operation of the environmental control device can accurately match the temperature comfort needs of most indoor users. In other embodiments, the heating mode can be determined as the operating mode when all heat exchange demands are heating demands, and the cooling mode can be determined as the operating mode when all heat exchange demands are cooling demands.

[0111] Specifically, when the indoor ambient temperature is lower than a third preset temperature, the heat exchange demand of the corresponding indoor space is determined to be a heating demand; when the indoor ambient temperature is greater than or equal to a fourth preset temperature, the heat exchange demand of the corresponding indoor space is determined to be a cooling demand; wherein the third preset temperature is less than or equal to the fourth preset temperature. In this embodiment, the third preset temperature is less than the fourth preset temperature. Based on this, when the indoor ambient temperature is greater than or equal to the third preset temperature and less than the fourth preset temperature, it can be determined that the indoor space has neither a cooling nor a heating demand.

[0112] In other embodiments, a characterization temperature representing the indoor heat exchange demand can be determined based on more than one indoor ambient temperature. For example, the average, maximum, or minimum value of more than one indoor ambient 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 fifth preset temperature, the cooling mode is determined as the operating mode; if the characterization temperature is greater than or equal to a sixth preset temperature, the heating mode is determined as the operating mode, where the fifth preset temperature is less than or equal to the sixth preset temperature.

[0113] In this embodiment, by determining the operating mode of the heat pump system based on the outdoor and / or indoor ambient temperatures as described above, it is beneficial to ensure that the operation of the heat pump system meets the user's comfort needs under the current environment, and to ensure that the system can automatically select a mode that precisely matches the user's comfort requirements. Furthermore, prioritizing the determination of the operating mode based on the outdoor ambient temperature, and using the indoor ambient temperature for secondary determination when the outdoor ambient temperature cannot determine the operating mode, further improves the accuracy of the determined operating mode, thereby achieving intelligent control of the environmental conditioning equipment while improving user comfort.

[0114] 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.
