[0054] The objectives, features, and advantages of this invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0055] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0056] Reference Figure 1 , Figure 1 This is a schematic diagram of the structure of a multi-split air conditioner in the hardware operating environment involved in the embodiments of the present invention.

[0057] like Figure 1 As shown, the multi-split air conditioner may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display screen and an input unit such as a keyboard; optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wireless-Fidelity (Wi-Fi) interface). The memory 1005 may be high-speed random access memory (RAM) or stable non-volatile memory (NVM), such as a disk storage device. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0058] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on multi-split air conditioners and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0059] like Figure 1 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a network communication module, a user interface module, and an air conditioner control program.

[0060] exist Figure 1 In the multi-split air conditioner shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the multi-split air conditioner of the present invention can be set in the multi-split air conditioner, and the multi-split air conditioner calls the air conditioner control program stored in the memory 1005 through the processor 1001 and executes the air conditioner control method provided in the embodiment of the present invention.

[0061] This invention provides an air conditioner control method, referring to... Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of an air conditioner control method according to the present invention.

[0062] In this embodiment, the air conditioner control method includes the following steps:

[0063] Step S10: Obtain the set temperature, set humidity, indoor ambient temperature and humidity of each air conditioner indoor unit.

[0064] It should be noted that the executing entity in this embodiment can be the air conditioner device, which has functions such as data processing, data communication, and program execution. The air conditioner device can be the controller of a multi-split air conditioner. Of course, other devices with similar functions can also be used, and this embodiment does not limit this. For ease of explanation, this embodiment uses the controller of a multi-split air conditioner as an example.

[0065] It is worth noting that the air conditioner in this embodiment refers to a multi-split air conditioner. A multi-split air conditioner is an air conditioner with one outdoor unit connected to multiple indoor units, which can simultaneously adjust parameters such as air temperature, humidity, cleanliness and air flow rate in multiple rooms, including but not limited to cooling, heating and fresh air circulation modes.

[0066] In this embodiment, the multi-split air conditioner is also equipped with a humidification device 20. The humidification device is connected to the humidification ports of multiple indoor air conditioners through humidification pipes. Since the humidification capacity of the humidification device is limited, in this embodiment, if the number of indoor air conditioners is small, the number of indoor air conditioners connected to the humidification device can be all the indoor air conditioners. If the number of indoor air conditioners is large, multiple humidification devices can be set in the multi-split air conditioner and connected to some of the indoor air conditioners respectively to achieve the optimal humidification effect.

[0067] In specific implementations, such as Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of a multi-split air conditioner in this embodiment. The outdoor unit of the air conditioner includes at least a compressor 1, a four-way valve 3, an outdoor heat exchanger 4, and an outdoor throttling element. The outdoor throttling element includes a main circuit electronic expansion valve 5, an economizer 6, and a main circuit second electronic expansion valve 7. The indoor unit of the air conditioner includes at least one indoor heat exchanger and an indoor throttling element. In this embodiment, the number of indoor heat exchangers in each indoor unit is set to at least two, namely a first indoor heat exchanger 11 (main indoor heat exchanger) and a second indoor heat exchanger 9 (auxiliary indoor heat exchanger). The first indoor heat exchanger 11 and the second indoor heat exchanger 9 are respectively provided with a first throttling element (main electronic expansion valve) and a second throttling element (auxiliary electronic expansion valve).

[0068] In the outdoor unit of the air conditioner, an exhaust solenoid valve 2 is provided between the refrigerant outlet of the compressor 1 and the four-way valve 3, a vapor-liquid separator 12 is provided between the refrigerant inlet of the compressor 1 and the four-way valve 3, an enthalpy injection solenoid valve 16 is provided between the economizer 6 and the compressor, and a subcooling solenoid valve 15 is provided between the economizer 6 and the vapor-liquid separator 12.

[0069] Pressure valves (pressure valve 17, pressure valve 18 and pressure valve 19) are also installed in the outdoor unit of the air conditioner.

[0070] In addition, in order to switch between different operating modes of the air conditioner, this embodiment also provides a high-pressure solenoid valve 13 and a low-pressure solenoid valve 14 in the outdoor unit of the air conditioner. These are mainly used to switch the refrigerant flow direction so as to change the operating state of the second indoor heat exchanger 9. The combination of the high-pressure solenoid valve 13 and the low-pressure solenoid valve 14 can also be replaced by a three-way valve or other components that can switch the pipeline path. This embodiment does not impose any specific restrictions on this.

[0071] It should be noted that the multi-split air conditioner control method in this embodiment is mainly applied to the cooling mode and the constant temperature and humidity mode. When the multi-split air conditioner is running in cooling mode, the high-pressure solenoid valve 13 is kept closed and the low-pressure solenoid valve 14 is kept open, so that the high-temperature and high-pressure refrigerant flows from the compressor outlet through the four-way valve 3 and the outdoor heat exchanger 4 into the indoor unit of the air conditioner. At this time, the refrigerant flowing into the indoor unit of the air conditioner is divided into two parts, which evaporate and absorb heat through the first indoor heat exchanger 11 and the second indoor heat exchanger 9 respectively, thereby reducing the indoor ambient temperature. Among them, the refrigerant flowing into the first indoor heat exchanger 11 flows directly back to the refrigerant inlet of the compressor 1 through the four-way valve 3 and the vapor-liquid separator 12, while the other part of the refrigerant flowing into the second indoor heat exchanger 9 flows directly back to the refrigerant inlet of the compressor 1 through the low-pressure solenoid valve 14 and the vapor-liquid separator 12, which is convenient for the next cooling cycle.

[0072] In constant temperature and humidity mode, the high-pressure solenoid valve 13 remains open and the low-pressure solenoid valve 14 remains closed, causing the high-temperature and high-pressure refrigerant to be divided into two parts from the compressor outlet. One part flows into the first indoor heat exchanger 11 in the air conditioner indoor unit through the four-way valve 3 and the outdoor heat exchanger 4 for evaporation and heat absorption, while the other part flows into the second indoor heat exchanger 9 in the air conditioner indoor unit through the high-pressure solenoid valve 13 for condensation and reheating. The refrigerant after condensation and reheating will then flow through the first indoor heat exchanger 11 again for evaporation and heat absorption, and finally merge and flow back to the refrigerant inlet of the compressor 1.

[0073] In a specific implementation, indoor ambient temperature and humidity can be collected by a temperature and humidity sensor installed in the area where the air conditioner unit is located, or by a temperature sensor or other devices that can perform the same or similar functions. This embodiment does not impose any specific restrictions on this.

[0074] Step S20: Determine the current temperature and humidity control stage of the air conditioner based on the set temperature, the set humidity, the indoor ambient temperature, and the indoor ambient humidity.

[0075] It is understandable that in this embodiment, the temperature and humidity control is divided into three stages. In the first stage, when the difference between the set temperature and the indoor ambient temperature is large, the indoor ambient temperature is rapidly reduced, and humidity control is not considered at this time (i.e., the humidifier is turned off). In the second stage, when the difference between the set temperature and the indoor ambient temperature is small, the rate of temperature reduction is reduced, and humidity control is also not considered. In the third stage, when the indoor ambient temperature is close to the set temperature, the humidifier is turned on to humidify the indoor environment in order to meet the user's humidity requirements.

[0076] Further, the step of determining the current temperature and humidity control stage of the air conditioner based on the set temperature, the set humidity, the indoor ambient temperature, and the indoor ambient humidity includes:

[0077] Determine the temperature difference between the indoor ambient temperature and the set temperature;

[0078] When the temperature difference is greater than the first threshold, the current temperature and humidity control stage is determined to be the first stage;

[0079] When the temperature difference is less than or equal to a first threshold and greater than a second threshold, the current temperature and humidity control stage is determined to be the second stage; and

[0080] When the temperature difference is less than or equal to the second threshold and the indoor humidity is less than the set humidity, the current temperature and humidity control stage is determined to be the third stage.

[0081] In specific implementation, the first threshold and the second threshold can differ by 2 degrees Celsius. This embodiment does not impose specific restrictions on this. For example, when the temperature difference between the indoor ambient temperature and the set temperature is greater than 4 degrees Celsius, it is the first stage, which requires rapid cooling; when the temperature difference between the indoor ambient temperature and the set temperature is less than or equal to 4 degrees Celsius and greater than 2 degrees Celsius, it is the second stage; when the temperature difference between the indoor ambient temperature and the set temperature is less than 2 degrees Celsius and the indoor ambient temperature is lower than the set humidity, it is the third stage, which involves humidity control.

[0082] Step S30: Adjust the operating parameters of the outdoor unit and each indoor unit of the air conditioner and the operating status of the humidification device according to the control strategy corresponding to the current temperature and humidity control stage.

[0083] It should be noted that, in this embodiment, adjusting the operating parameters of the outdoor unit and each indoor unit of the air conditioner specifically includes: adjusting the operating frequency of the compressor, adjusting the speed of the outdoor fan and the opening degree of the main throttling element, adjusting the opening degree of the first throttling element and adjusting the opening degree of the second throttling element; adjusting the operating state of the humidification device specifically means turning the humidification device on or off, and adjusting the valve opening degree of the humidification port according to the different stages of each indoor unit of the air conditioner. This embodiment does not impose specific limitations on this.

[0084] This embodiment acquires the set temperature, set humidity, indoor ambient temperature, and indoor ambient humidity of each indoor unit of the air conditioner. Based on the acquired set temperature, set humidity, indoor ambient temperature, and indoor ambient humidity, it determines the current temperature and humidity control stage of the air conditioner. Finally, based on the control strategy corresponding to the current temperature and humidity control stage of the air conditioner, it adjusts the operating parameters of each component in the outdoor unit and each indoor unit of the air conditioner, and adjusts the operating status of the humidification device to achieve simultaneous control of indoor ambient temperature and humidity. This avoids the technical problem in the prior art where multi-split air conditioners cannot simultaneously achieve indoor temperature and humidity control, thus improving the user experience.

[0085] refer to Figure 4 , Figure 4 This is a flowchart illustrating a second embodiment of an air conditioner control method according to the present invention.

[0086] Based on the first embodiment described above, in this embodiment, step S30 includes:

[0087] Step S301: Obtain the current operating parameters of the air conditioner.

[0088] It should be noted that the current operating parameters of the air conditioner include, but are not limited to: the evaporation temperature of the compressor, the first subcooling degree corresponding to the outdoor heat exchanger, the first superheat degree corresponding to the first indoor heat exchanger, and the second subcooling degree corresponding to the second indoor heat exchanger.

[0089] Step S302: Correct the current operating parameters according to the control strategy corresponding to the current temperature and humidity control stage to obtain the target operating parameters.

[0090] In actual operation, the objectives to be achieved at different stages are different. For example, in the first stage, rapid cooling is required. This can be achieved by increasing the compressor operating frequency, increasing the outdoor fan speed, increasing the opening of the main circuit throttling element, and increasing the refrigerant flow of the indoor heat exchanger (increasing the opening of the corresponding throttling element of the indoor heat exchanger). It can also be achieved by increasing the indoor fan speed and the valve opening of the air outlet. This embodiment does not impose specific restrictions on these aspects.

[0091] The above adjustment process requires control based on different types of parameter values ​​to facilitate precise cooling or temperature control of the air conditioner. Therefore, this embodiment achieves real-time control of different components by modifying the corresponding operating parameters of different components.

[0092] Further, the step of correcting the current operating parameters according to the control strategy corresponding to the current temperature and humidity control stage to obtain the target operating parameters includes:

[0093] The previous evaporation temperature of the compressor, the previous first subcooling of the outdoor heat exchanger, the previous superheat of the first indoor heat exchanger, and the previous second subcooling of the second indoor heat exchanger are obtained.

[0094] Determine the correction coefficients corresponding to each operating parameter in the current temperature and humidity control phase; and

[0095] The evaporation temperature, first subcooling, first superheat, and second subcooling are corrected according to the correction coefficients to obtain the target operating parameters.

[0096] In practical implementation, the objectives to be achieved at different stages are different, and therefore the correction coefficients at different stages are also different. Taking the constant temperature and humidity mode as an example, in the first stage, if the user's demand is to quickly reduce the room temperature, the humidifier 20 in the multi-split air conditioner is turned off, and no determination is made regarding humidity demand; the outdoor compressor 1 controls the frequency increase and decrease based on the compressor's evaporation temperature Te, and Te is corrected at this time: Ten = Ten-1 - C2 (Ten is the current evaporation temperature, Ten-1 is the previous evaporation temperature, and C2 is a constant); the outdoor fan and electronic expansion valve 7 control the speed and opening adjustment based on the subcooling degree Sdo of the outdoor heat exchanger, and Sdo is corrected: Sdon = Sdon-1 - F2 (Sdon is the current subcooling degree, Sdon-1 is the previous subcooling degree, and F2 is a constant); the indoor main electronic expansion valve 10 adjusts the opening based on the superheat Tt of the indoor main heat exchanger 11, and Tt is corrected: Ttn = Ttn-1 -D2 (Ttn is the superheat at the current moment, Ttn-1 is the superheat at the previous moment, and D2 is a constant); The indoor auxiliary electronic expansion valve 8 adjusts its opening according to the subcooling Sdi of the indoor auxiliary heat exchanger 9 and corrects Sdi: Sdin=Sdin-1-E2 (Sdin is the subcooling at the current moment, Sdin-1 is the subcooling at the previous moment, and E2 is a constant).

[0097] In the second stage, the humidifier 20 is turned off, and no humidity requirement is determined; the outdoor compressor is controlled to increase or decrease frequency according to the target evaporation temperature Te; the outdoor fan and electronic expansion valve 7 are controlled to adjust speed and opening according to the subcooling degree Sdo of the outdoor heat exchanger; the indoor main electronic expansion valve 10 is adjusted to adjust opening according to the superheat degree Tt of the indoor main heat exchanger; and the indoor auxiliary electronic expansion valve 8 is adjusted to adjust opening according to the subcooling degree Sdi of the indoor auxiliary heat exchanger.

[0098] In the third stage, it is determined that the indoor ambient temperature meets the user's needs, and humidity requirements are also assessed. The humidifier 20 is activated to humidify the room and meet the user's humidity requirements. The outdoor compressor control adjusts the frequency based on the target evaporation temperature Te, and Te is corrected as follows: Ten = Ten-1 + C1 (C1 is a constant). The outdoor fan and electronic expansion valve control adjust the speed and opening based on the subcooling degree Sdo of the outdoor heat exchanger, and Sdo is corrected as follows: Sdon = Sdon-1 + F1 (F1 is a constant). The indoor main electronic expansion valve 10 adjusts the opening based on the superheat degree Tt of the indoor main heat exchanger, and Tt is corrected as follows: Ttn = Ttn-1 + D1 (D1 is a constant). The indoor auxiliary electronic expansion valve 8 adjusts the opening based on the subcooling degree Sdi of the indoor auxiliary heat exchanger, and Sdi is corrected as follows: Sdin = Sdin-1 + E1 (E1 is a constant).

[0099] In practical implementation, since the temperature and humidity control stage of the air conditioner is determined based on the temperature difference between the indoor ambient temperature and the set temperature, as well as the relationship between the indoor ambient humidity and the set humidity, there may be cases where it directly enters the third stage or the second stage. In this embodiment, it is only necessary to complete the third stage during the temperature and humidity control process.

[0100] Furthermore, depending on the purpose of each stage, in this embodiment, the first correction coefficient increases sequentially based on the first stage, the second stage, and the third stage; the second correction coefficient decreases sequentially based on the first stage, the second stage, and the third stage; the third correction coefficient decreases sequentially based on the first stage, the second stage, and the third stage; and the fourth correction coefficient decreases sequentially based on the first stage, the second stage, and the third stage.

[0101] Step S303: Adjust the operating parameters of the outdoor unit and each indoor unit of the air conditioner based on the target operating parameters.

[0102] It should be noted that in this embodiment, the operating frequency of the compressor, the speed of the outdoor fan, the opening degree of the main throttling element, the opening degree of the first throttling element, and the opening degree of the second throttling element are adjusted.

[0103] Furthermore, adjusting the operating parameters of the outdoor unit and each indoor unit of the air conditioner based on the target operating parameters includes:

[0104] Adjust the compressor's operating frequency according to the target evaporation temperature;

[0105] Adjust the speed of the outdoor fan and the opening of the main throttling element according to the target first subcooling degree;

[0106] Adjust the opening degree of the first throttling element according to the target first superheat; and

[0107] Adjust the opening of the second throttling element according to the target second subcooling.

[0108] In practice, the target evaporation temperature refers to the corrected compressor evaporation temperature, the target first subcooling refers to the corrected first subcooling of the outdoor heat exchanger, the target first superheat refers to the corrected first superheat of the first indoor heat exchanger, and the target second subcooling refers to the corrected second subcooling of the second indoor heat exchanger.

[0109] Step S304: Adjust the operating status of the humidification device according to the current temperature and humidity control stage.

[0110] In practice, the humidifier is turned off when the current temperature and humidity control stage is the first or second stage, and turned on when the current temperature and humidity control stage is the third stage.

[0111] This embodiment corrects the compressor's evaporation temperature, the first subcooling of the outdoor heat exchanger, the first superheat of the first indoor heat exchanger, and the second subcooling of the second indoor heat exchanger in the air conditioner according to the control strategies corresponding to different temperature and humidity control stages. This allows for adjustments to the compressor's operating frequency based on the target evaporation temperature; the outdoor fan speed and the opening of the main throttling element based on the target first subcooling; the opening of the first throttling element based on the target first superheat; and the opening of the second throttling element based on the target second subcooling. This achieves temperature and humidity control at different stages, ultimately completing the temperature and humidity control during the operation of the multi-split air conditioner and meeting the user's needs.

[0112] refer to Figure 5 , Figure 5 This is a flowchart illustrating a third embodiment of an air conditioner control method according to the present invention.

[0113] Based on the first embodiment described above, in this embodiment, before step S10, the method further includes:

[0114] Step S01: Obtain the current operating mode of each indoor air conditioner unit.

[0115] In this embodiment, the current operating mode of each indoor air conditioner unit is the same, either all are in cooling mode or all are in constant temperature and humidity mode. Therefore, the refrigerant pipes between each indoor air conditioner unit and the outdoor air conditioner unit are shared pipes. In order to prevent refrigerant liquid backflow from affecting the normal operation, this embodiment keeps the operating mode of each indoor air conditioner unit consistent.

[0116] In addition, at the expense of increasing costs, a combination of a high-pressure solenoid valve 13 and a low-pressure solenoid valve 14 or a three-way valve or other reversing device can be added to the second indoor heat exchanger in each air conditioner unit to control the refrigerant flow direction, so as to realize the special customization of the operating mode of each air conditioner unit (different modes can be operated).

[0117] It is understandable that the reversing device refers to the combination of the high-pressure solenoid valve 13 and the low-pressure solenoid valve 14, which is mainly used to switch the refrigerant flow direction in order to change the operating state of the second indoor heat exchanger 9. In the cooling mode, the second indoor heat exchanger 9 is mainly used for evaporation and heat absorption, and in the constant temperature and humidity mode, the second indoor heat exchanger 9 is mainly used for condensation and reheat.

[0118] Furthermore, the combination of high-pressure solenoid valve 13 and low-pressure solenoid valve 14 can also be replaced by a three-way valve or other components that can switch pipeline paths; this embodiment does not impose specific limitations on this.

[0119] Step S02: When the current operating mode is cooling mode, connect the first end and the third end of the reversing device to connect the second indoor heat exchanger with the refrigerant inlet of the compressor.

[0120] When the multi-split air conditioner is in cooling mode, the high-pressure solenoid valve 13 remains closed and the low-pressure solenoid valve 14 remains open, allowing the high-temperature, high-pressure refrigerant to flow from the compressor outlet through the four-way valve 3 and the outdoor heat exchanger 4 into the indoor unit. At this time, the refrigerant flowing into the indoor unit is divided into two parts, which evaporate and absorb heat through the first indoor heat exchanger 11 and the second indoor heat exchanger 9 respectively, reducing the indoor ambient temperature. The refrigerant flowing into the first indoor heat exchanger 11 flows directly back to the refrigerant inlet of the compressor 1 through the four-way valve 3 and the vapor-liquid separator 12, while the other part of the refrigerant flowing into the second indoor heat exchanger 9 flows directly back to the refrigerant inlet of the compressor 1 through the low-pressure solenoid valve 14 and the vapor-liquid separator 12, facilitating the next cooling cycle.

[0121] In this embodiment, when the multi-split air conditioner is operating in cooling mode, in the first stage, it is determined that the user's demand is to quickly reduce the room temperature, so the humidifier 20 is turned off, and no determination is made regarding humidity demand; the outdoor compressor 1 is controlled to operate at higher and lower frequencies based on the evaporation temperature Te, and Te is corrected as follows: Ten = Ten-1 - C2 (Ten is the current evaporation temperature, Ten-1 is the previous evaporation temperature, and C2 is a constant); the outdoor fan and electronic expansion valve 7 are controlled to adjust the speed and opening based on the subcooling degree Sdo of the outdoor heat exchanger, and Sdo is corrected as follows: Sdon = Sdon-1 - F2 (Sdon is the current subcooling degree, Sdon-1 is the previous subcooling degree, and F2 is a constant); the indoor main electronic expansion valve 10 is adjusted to adjust the opening based on the superheat Tt of the indoor main heat exchanger 11, and Tt is corrected as follows: Ttn = Ttn-1 -D2 (Ttn is the superheat at the current moment, Ttn-1 is the superheat at the previous moment, and D2 is a constant); The indoor auxiliary electronic expansion valve 8 adjusts its opening according to the superheat Tta of the indoor auxiliary heat exchanger 9, and corrects Tta: Ttan=Ttan-1 -G2 (Ttan is the subcooling at the current moment, Ttan-1 is the subcooling at the previous moment, and G2 is a constant).

[0122] In the second stage, the humidifier 20 is turned off, and no humidity requirement is determined; the outdoor compressor is controlled to increase or decrease frequency according to the evaporation temperature Te; the outdoor fan and electronic expansion valve 7 are controlled to adjust speed and opening according to the subcooling degree Sdo of the outdoor heat exchanger; the indoor main electronic expansion valve 10 is adjusted to adjust opening according to the superheat degree Tt of the indoor main heat exchanger; and the indoor auxiliary electronic expansion valve 8 is adjusted to adjust opening according to the superheat degree Tta of the indoor auxiliary heat exchanger.

[0123] In the third stage, it is determined that the room temperature meets the user's needs, and humidity requirements are also considered. The humidifier 20 in the air conditioning unit is activated to humidify the room and meet the user's humidity requirements. The outdoor compressor control adjusts the frequency based on the evaporation temperature Te, and Te is corrected as follows: Ten = Ten-1 + C1 (C1 is a constant). The outdoor fan and electronic expansion valve control adjust the speed and opening based on the subcooling degree Sdo of the outdoor heat exchanger, and Sdo is corrected as follows: Sdon = Sdon-1 + F1 (F1 is a constant). The indoor main electronic expansion valve 10 adjusts the opening based on the superheat degree Tt of the indoor main heat exchanger, and Tt is corrected as follows: Ttn = Ttn-1 + D1 (D1 is a constant). The indoor auxiliary electronic expansion valve 8 adjusts the opening based on the superheat degree Tta of the indoor auxiliary heat exchanger, and Tta is corrected as follows: Ttan = Ttan-1 + E1 (E1 is a constant).

[0124] Step S03: When the current operating mode is constant temperature and humidity mode, connect the first end and the second end of the reversing device so that the second indoor heat exchanger is connected to the refrigerant outlet of the compressor.

[0125] When the multi-split air conditioner is running in constant temperature and humidity mode, the high-pressure solenoid valve 13 remains open and the low-pressure solenoid valve 14 remains closed, so that the high-temperature and high-pressure refrigerant is divided into two parts from the compressor outlet. One part flows into the first indoor heat exchanger 11 in the air conditioner indoor unit through the four-way valve 3 and the outdoor heat exchanger 4 for evaporation and heat absorption, while the other part flows into the second indoor heat exchanger 9 in the air conditioner indoor unit through the high-pressure solenoid valve 13 for condensation and reheating. The refrigerant after condensation and reheating will then flow through the first indoor heat exchanger 11 again for evaporation and heat absorption, and finally merge and flow back to the refrigerant inlet of the compressor 1.

[0126] In constant temperature and humidity mode, the temperature and humidity control logic for multi-split air conditioners is the same as above, but the correction coefficient is different, which makes the temperature change rate in constant temperature and humidity mode less than the temperature change rate in cooling mode.

[0127] This embodiment determines the current operating mode of the multi-split air conditioner before adjusting the temperature and humidity, and adjusts the on / off state of the high-pressure solenoid valve and the low-pressure solenoid valve according to different operating modes to achieve mode switching and improve the efficiency of subsequent temperature and humidity control.

[0128] Furthermore, this embodiment of the invention also proposes a storage medium storing an air conditioner control program, which, when executed by a processor, implements the steps of the air conditioner control method described above.

[0129] Since this storage medium adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
