[0002] With the development of economy and technology and the continuous improvement of people's living standards, air conditioners are being used more and more widely in people's daily lives, and their performance is also constantly improving. Currently, air conditioners generally have heating elements installed in the air outlet duct of the indoor unit. These heating elements can be turned on during cooling or dehumidification operation to prevent condensation from accumulating on their surface.

[0003] However, the heat generated when the heating element is turned on during the cooling or dehumidifying operation of an air conditioner can offset the cooling capacity of the air conditioner itself, which can easily reduce the cooling performance of the air conditioner and affect the comfort of indoor users.

[0023] Optionally, the heating control parameters include the input voltage of the heating module;

[0024] And / or, the step of determining the heating control parameters of the heating module and / or the frequency adjustment value of the air conditioner's compressor based on the first indoor ambient temperature and the operating speed includes:

[0042] In addition, to achieve the above objectives, this application also proposes a computer-readable storage medium storing a control program for an air conditioner, which, when executed by a processor, implements the steps of the control method for the air conditioner as described in any of the preceding claims.

[0043] This invention proposes a control method for an air conditioner. Based on an air conditioner with a heating module, an indoor heat exchanger, and an indoor fan installed in the air outlet duct, this method controls the operation of the heating module by adjusting heating control parameters determined according to the indoor ambient temperature and the operating speed of the indoor fan when the air conditioner is in cooling or dehumidifying operation. This effectively avoids excessive heating by the heating module leading to insufficient cooling capacity. Furthermore, / or, by adjusting frequency parameters determined according to the indoor ambient temperature and the operating speed of the indoor fan, the compressor frequency is increased. Increasing the compressor frequency increases the cooling capacity of the air conditioner, effectively compensating for the cooling capacity loss caused by the heating module being activated. Therefore, this solution can prevent condensation on the surface of the heating module while ensuring sufficient cooling capacity to meet indoor comfort requirements. Attached Figure Description

[0049] 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

[0050] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0051] The main solution of this invention is as follows: Based on an air conditioner with a heating module, an indoor heat exchanger, and an indoor fan installed in the air outlet duct, when the air conditioner is in cooling or dehumidifying operation, the first indoor ambient temperature of the space in which the air conditioner operates and the operating speed of the indoor fan are obtained; the heating control parameters of the heating module and / or the frequency adjustment value of the air conditioner's compressor are determined based on the first indoor ambient temperature and the operating speed; the operation of the heating module is controlled according to the heating control parameters, and / or, when the heating module is turned on, the frequency of the compressor is increased according to the frequency adjustment value, so that the temperature of the heating module is higher than the dew point temperature and the cooling capacity of the air conditioner is not lower than the set cooling capacity.

[0052] In existing technology, the heat generated when the heating element is turned on during the cooling or dehumidifying operation of an air conditioner can offset the cooling capacity of the air conditioner itself, which can easily reduce the cooling performance of the air conditioner and affect the comfort of indoor users.

[0053] The present invention provides the above-mentioned solution, which aims to prevent condensation on the surface of the heating element while ensuring that the air conditioner outputs sufficient cooling capacity to meet indoor comfort requirements.

[0054] This invention provides an air conditioner. The air conditioner can be any type, such as a wall-mounted air conditioner, a floor-standing air conditioner, a portable air conditioner, a window air conditioner, or a ceiling-mounted air conditioner.

[0055] In this embodiment, the air conditioner includes a heating module 2, an indoor heat exchanger, an indoor fan 3, a compressor 4, and a control device 1.

[0056] The air conditioner has an air outlet duct, and the heating module 2, indoor heat exchanger, and indoor fan 3 are located inside the air outlet duct. The distances from the indoor heat exchanger, heating module 2, and indoor fan 3 to the air outlet of the air conditioner decrease sequentially. The indoor heat exchanger is connected to the compressor 4 via refrigerant piping.

[0057] In this embodiment, heating module 2 is an electric heating module; in other implementations, heating module 2 may also be other types of heating modules with adjustable heating capacity, such as a heat storage module with temperature regulation function, or a temperature-adjustable module that converts wind energy into heat energy.

[0058] Specifically, the air conditioner includes a refrigerant circulation loop, which comprises a compressor 4, an outdoor heat exchanger, a throttling device, and an indoor heat exchanger connected in sequence. When the air conditioner is in cooling or dehumidifying operation, the refrigerant discharged from the compressor 4 flows sequentially through the outdoor heat exchanger, the throttling device, and the indoor heat exchanger before returning to the compressor 4. At this time, the outdoor heat exchanger is in a condensing state releasing heat, while the indoor heat exchanger is in an evaporating state absorbing heat.

[0059] The heating module 2, indoor fan 3 and compressor 4 mentioned above are all connected to the control device 1, which can be used to control the operation of the above components.

[0060] Furthermore, the air conditioner may also include a temperature detection module 5, which is connected to the control device 1. The control device 1 can acquire the temperature data detected by the temperature detection module 5. The temperature detection module 5 may include an indoor temperature sensor, which is specifically used to detect the indoor ambient temperature within the operating space of the air conditioner. The indoor temperature sensor may be located in the indoor environment outside the air conditioner or at the air return vent of the air conditioner. Furthermore, the temperature detection module 5 may also include an outdoor temperature sensor, which is specifically used to detect the outdoor ambient temperature. The outdoor temperature sensor may be located at the outdoor unit.

[0061] Furthermore, the air conditioner may also include a humidity detection module 6, which is connected to the control device 1. The control device 1 can acquire the humidity data detected by the humidity detection module 6. The humidity detection module 6 is specifically used to detect the indoor humidity within the space where the air conditioner operates. The humidity detection module 6 can be located in the indoor environment outside the air conditioner or at the air return vent of the air conditioner.

[0062] Reference Figure 1 The control device 1 of the air conditioner includes a processor 1001 (e.g., CPU), a memory 1002, and a timer 1003, etc. These components 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.

[0063] Those skilled in the art will understand that Figure 1 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.

[0064] like Figure 1 As shown, the memory 1002, which is a computer-readable storage medium, may include a control program for an air conditioner. Figure 1 In the device shown, the processor 1001 can be used to call the control program of the air conditioner stored in the memory 1002 and execute the relevant steps of the control method of the air conditioner in the following embodiments.

[0065] This invention also provides a control method for an air conditioner, which is used to control the air conditioner described above.

[0066] Reference Figure 2This application proposes an embodiment of a control method for an air conditioner. In this embodiment, the control method for the air conditioner includes:

[0067] Step S10: When the air conditioner is in cooling or dehumidifying operation, obtain the first indoor ambient temperature of the space where the air conditioner operates and the operating speed of the indoor fan.

[0068] The cooling operation here specifically refers to the air conditioning operation mode where the indoor heat exchanger is in an evaporating state and the goal is to lower the indoor ambient temperature. The dehumidification operation here specifically refers to the air conditioning operation mode where the indoor heat exchanger is in an evaporating state and the goal is to lower the indoor ambient humidity.

[0069] Specifically, the indoor temperature sensor data can be acquired at preset intervals or in real time as the initial indoor ambient temperature. The operating speed of the indoor fan's drive motor can be obtained by acquiring its operating parameters at preset intervals or in real time.

[0070] It should be noted that the indoor ambient temperature and the operating speed of the indoor fan are detected simultaneously.

[0071] Step S20: Determine the heating control parameters of the heating module and / or the frequency adjustment value of the air conditioner's compressor based on the first indoor ambient temperature and the operating speed;

[0072] The heating control parameters are specifically parameters used to regulate the heating amount of the heating module. In this embodiment, the heating control parameters include the input voltage of the heating module. In other embodiments, the heating control parameters include the input current or operating power of the heating module, etc.

[0073] The frequency adjustment value is specifically the deviation between the current frequency of the air conditioner in cooling or dehumidifying operation and the target frequency required for the compressor to operate.

[0074] In this embodiment, heating control parameters and frequency adjustment values ​​are determined based on the first indoor ambient temperature and operating speed. Specifically, the heating control parameters can be determined simultaneously based on the first indoor ambient temperature and operating speed; alternatively, the heating control parameters can be determined first, and then the frequency adjustment value corresponding to the first indoor ambient temperature and operating speed can be determined based on the heating control parameters; or the frequency adjustment value can be determined first, and then the heating control parameters corresponding to the first indoor ambient temperature and operating speed can be determined based on the frequency adjustment value. In other embodiments, one of the heating control parameters and frequency adjustment values ​​can be determined based on the first indoor ambient temperature and operating speed.

[0075] Different initial indoor ambient temperatures and different operating speeds correspond to different heating control parameters. The initial correspondence between the initial indoor ambient temperature, operating speed, and heating control parameters can be preset, and can take the form of a calculation formula, mapping table, algorithm model, etc. Based on the initial correspondence, the heating control parameters can be calculated by substituting the initial indoor ambient temperature and operating speed into the initial preset formula, or by querying the initial preset mapping table using the initial indoor ambient temperature and operating speed, and using the result matched in the initial preset mapping table as the heating control parameters. Specifically, when determining the frequency adjustment value based on the initial indoor ambient temperature and operating speed before determining the heating control parameters, this initial correspondence can be obtained based on the frequency adjustment value.

[0076] Different initial indoor ambient temperatures and different operating speeds correspond to different frequency adjustment values. A second correspondence between the initial indoor ambient temperature, operating speed, and frequency adjustment value can be preset, and can take the form of a calculation formula, mapping table, algorithm model, etc. Based on this second correspondence, the frequency adjustment value can be calculated by substituting the initial indoor ambient temperature and operating speed into the second preset formula, or by querying the second preset mapping table using the initial indoor ambient temperature and operating speed, and using the result matched in the second preset mapping table as the frequency adjustment value. Specifically, when determining the heating control parameters based on the initial indoor ambient temperature and operating speed before determining the frequency adjustment value, this second correspondence can be obtained based on the heating control parameters.

[0077] Step S30: Control the operation of the heating module according to the heating control parameters, and / or, when the heating module is turned on, increase the frequency of the compressor according to the frequency adjustment value, so that the temperature of the heating module is higher than the dew point temperature and the cooling capacity of the air conditioner is not lower than the set cooling capacity.

[0078] When the heating module is turned on, the compressor frequency is increased. The heating control parameters of the heating module can be preset fixed parameters or parameters determined based on the first indoor ambient temperature and the operating speed.

[0079] The dew point temperature here refers to the temperature required for condensation to form on the air in the air outlet duct. The temperature of the heating module refers to the surface temperature of the heating module. If the surface temperature of the heating module is higher than the dew point temperature, the air in the air outlet duct will not condense on the surface of the heating module when it reaches the surface of the heating module.

[0080] The set cooling capacity is the minimum cooling output required by the air conditioner to achieve indoor cooling or dehumidification. The outlet air temperature of the air conditioner can be detected here. If the outlet air temperature is lower than the preset temperature value, the cooling capacity is considered to be no less than (i.e., greater than or equal to) the set cooling capacity. The preset temperature value is determined based on the air conditioner's set temperature (i.e., the target indoor temperature) during cooling or dehumidification operation; the lower the set temperature, the lower the preset temperature value. When the air conditioner's cooling capacity is no less than the set cooling capacity, the temperature change in the indoor environment at preset intervals is no less than the set temperature change value.

[0081] This invention proposes a control method for an air conditioner. Based on an air conditioner with a heating module, an indoor heat exchanger, and an indoor fan installed in the air outlet duct, this method controls the operation of the heating module by adjusting heating control parameters determined according to the indoor ambient temperature and the operating speed of the indoor fan when the air conditioner is in cooling or dehumidifying mode. This effectively prevents excessive heating by the heating module from causing insufficient cooling capacity. Furthermore, / or, by adjusting frequency parameters determined according to the indoor ambient temperature and the operating speed of the indoor fan, the compressor frequency is increased. Increasing the compressor frequency increases the cooling capacity of the air conditioner, effectively compensating for the cooling capacity loss caused by the heating module being activated. Therefore, this solution can prevent condensation on the surface of the heating module while ensuring sufficient cooling capacity to meet indoor comfort requirements.

[0082] Furthermore, based on the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, reference is made to... Figure 3 The first preset relationship is defined as the pre-set correspondence between the first indoor ambient temperature, the operating speed, and the first heating control parameter. The step of determining the heating control parameter of the heating module based on the first indoor ambient temperature and the operating speed includes:

[0083] Step S21: Based on the first preset relationship, determine the first heating control parameter corresponding to the first indoor ambient temperature and the operating speed as the heating control parameter;

[0084] In the first preset relationship, the heating capacity of the heating module corresponding to the heating control parameter increases with the increase of the first indoor ambient temperature, and the heating capacity of the heating module corresponding to the heating control parameter increases with the increase of the operating speed.

[0085] Conversely, in the first preset relationship, the heating amount of the heating module corresponding to the heating control parameter decreases as the first indoor ambient temperature decreases, and the heating amount of the heating module corresponding to the heating control parameter decreases as the operating speed decreases.

[0086] When the first preset relationship is a calculation formula, the first indoor ambient temperature and the operating speed can be substituted into the first preset relationship, and the calculated result can be used as the heating control parameter.

[0087] When the first preset relationship is a mapping table, the first preset relationship will be queried by the first indoor ambient temperature and the operating speed, and the matching result will be used as the heating control parameter.

[0088] In this embodiment, the compressor's current operating frequency (i.e., the compressor frequency before adjustment using the frequency adjustment value) tends to increase as the first indoor ambient temperature increases; the compressor's current operating frequency tends to decrease as the first indoor ambient temperature decreases.

[0089] In this embodiment, the risk of condensation on the heating module varies depending on the first indoor ambient temperature and the operating speed, and the effect of the heating amount of the heating module on the cooling capacity also varies. Based on the first preset relationship, the heating amount of the heating module is increased to adapt to the increase of the first indoor ambient temperature and the operating speed, which can ensure the cooling effect of the air conditioner while ensuring that no condensation occurs on the surface of the heating module.

[0090] Furthermore, in this embodiment, after step S10, the method further includes: when the first indoor ambient temperature is less than the first preset temperature, determining the second heating control parameter as the heating control parameter; when the first indoor ambient temperature is greater than or equal to the first preset temperature, performing the step of determining the first heating control parameter corresponding to the first indoor ambient temperature and the operating speed as the heating control parameter based on the first preset relationship; the heating amount of the heating module corresponding to the second heating control parameter is less than the heating amount of the heating module corresponding to the first heating control parameter.

[0091] In this embodiment, when the first indoor ambient temperature is sufficiently low (below the first preset temperature), the risk of condensation on the heating module is low and the indoor cooling demand is small. The heating capacity of the heating module no longer changes with the changes in the first indoor ambient temperature and the operating speed. Instead, the heating module is controlled by the second heating control parameter to output the minimum heating capacity, which can effectively prevent condensation from forming on the surface of the heating module while ensuring indoor comfort. Conversely, when the first indoor ambient temperature is high, the risk of condensation on the heating module is high and the indoor cooling demand is large. The heating capacity of the heating module adapts to the changes in the first indoor ambient temperature and the operating speed, which can effectively prevent condensation on the heating module while ensuring sufficient cooling capacity to meet indoor comfort requirements.

[0092] Furthermore, based on any of the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, the second preset relationship is defined as the pre-set correspondence between the first indoor ambient temperature, the operating speed, and the first frequency adjustment value, referring to... Figure 4 The step of determining the frequency adjustment value of the air conditioner's compressor based on the first indoor ambient temperature and the operating speed includes:

[0093] Step S22: Based on the second preset relationship, determine the first frequency adjustment value corresponding to the first indoor ambient temperature and the operating speed as the frequency adjustment value;

[0094] In the second preset relationship, the frequency adjustment value increases with the increase of the first indoor ambient temperature, and the frequency adjustment value increases with the increase of the operating speed.

[0095] Conversely, in the second preset relationship, the frequency adjustment value decreases as the first indoor ambient temperature decreases, and the frequency adjustment value decreases as the operating speed decreases.

[0096] When the second preset relationship is a calculation formula, the first indoor ambient temperature and the operating speed can be substituted into the second preset relationship, and the calculated result can be used as the frequency adjustment value.

[0097] When the second preset relationship is a mapping table, the second preset relationship will be queried through the first indoor ambient temperature and the operating speed, and the matching result will be used as the frequency adjustment value.

[0098] In this embodiment, the risk of condensation on the heating module varies depending on the first indoor ambient temperature and the operating speed, and the effect of the heating amount on the cooling capacity also varies. Based on the second preset relationship, the compressor frequency adjustment value is increased to adapt to the increase of the first indoor ambient temperature and the operating speed. This allows the cooling capacity of the air conditioner to increase with the increase of the first indoor ambient temperature and the operating speed, thereby preventing condensation on the heating module while ensuring that sufficient cooling capacity is provided to meet indoor comfort requirements.

[0099] Furthermore, in this embodiment, after step S10, the method further includes: when the first indoor ambient temperature is less than the second preset temperature, determining the second frequency adjustment value as the frequency adjustment value; when the first indoor ambient temperature is greater than or equal to the first preset temperature, performing the step of determining the first frequency adjustment value corresponding to the first indoor ambient temperature and the operating speed as the frequency adjustment value based on the second preset relationship; wherein, the second frequency adjustment value is less than the first frequency adjustment value.

[0100] In this embodiment, the second preset temperature is greater than the first preset temperature described above. In other embodiments, the second preset temperature may be less than or equal to the first preset temperature.

[0101] In this embodiment, the second frequency adjustment value is 0; in other embodiments, the second frequency adjustment value may also be other values ​​greater than 0.

[0102] In this embodiment, when the second indoor ambient temperature is sufficiently low (below the second preset temperature), the risk of condensation on the heating module is low and the indoor cooling demand is small. The frequency adjustment value no longer changes with the changes in the first indoor ambient temperature and operating speed. Instead, the compressor is controlled to maintain the current frequency or increase the frequency by a small margin through the second frequency adjustment value. This effectively prevents condensation from forming on the surface of the heating module while ensuring indoor comfort. Conversely, when the first indoor ambient temperature is high, the risk of condensation on the heating module is high and the indoor cooling demand is large. The compressor frequency increases with the increase in the first indoor ambient temperature and operating speed. This effectively prevents condensation on the heating module while ensuring sufficient cooling capacity to meet indoor comfort requirements.

[0103] Furthermore, based on any of the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, reference is made to... Figure 5 Step S20 includes:

[0104] Step S201: Query the preset mapping table, and use the preset heating control parameter mapped to the first indoor ambient temperature and the operating speed in the preset mapping table as the heating control parameter, and / or use the preset frequency adjustment value mapped to the first indoor ambient temperature and the operating speed in the preset mapping table as the frequency adjustment value.

[0105] In this embodiment, the preset mapping table includes preset heating control parameters and preset frequency adjustment values ​​corresponding to different indoor ambient temperatures and different operating speeds. Specifically, the preset mapping table may include the first preset relationship and the second preset relationship involved in the above embodiments.

[0106] For example, let T1 be the first indoor ambient temperature, V be the input voltage of the heating module (i.e., the heating control parameter), and Fr be the frequency adjustment value. The indoor fan can be set with different fan speeds (such as 0%, 20%, 40%, 60%, 80%, 100%) to represent different operating speeds. The preset mapping table is shown in the table below:

[0107]

[0108] Based on the table above, 20℃ in the table can be the first preset temperature mentioned in the above embodiments, and 25℃ in the table can be the second preset temperature mentioned in the above embodiments.

[0109] When T1 is 23℃ and the indoor fan is running at 60% speed, the heating control parameter can be determined to be 54V and the frequency adjustment value can be determined to be 0Hz. Then, the 54V voltage is input to the heating module and the compressor maintains the current frequency. When T1 is 28℃ and the indoor fan is running at 80% speed, the heating control parameter can be determined to be 127V and the frequency adjustment value can be determined to be 4Hz. Then, the 127V voltage is input to the heating module and the compressor frequency is increased to 4Hz.

[0110] In other embodiments, in the preset mapping table, different indoor ambient temperatures and different operating speeds and their mapped parameters can be one of preset heating control parameters and preset frequency adjustment values.

[0111] In this embodiment, the corresponding parameters are determined by using the first indoor ambient temperature and the operation lookup table to regulate the heating module and / or compressor. This not only prevents condensation on the heating module while ensuring sufficient cooling capacity to meet indoor comfort needs, but also helps to improve the stability of the air conditioner's operation.

[0112] Furthermore, based on any of the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed.

[0113] In this embodiment, when the air conditioner is in cooling or dehumidifying operation, if the air conditioner meets at least one sub-condition of the first target condition, then the step of obtaining the first indoor ambient temperature of the space in which the air conditioner operates and the operating speed of the indoor fan is executed.

[0114] The first objective condition includes the following sub-conditions:

[0115] The first indoor ambient humidity in the space where the air conditioner operates is greater than the first set humidity.

[0116] The duration of the air conditioner's cooling or dehumidifying operation is greater than or equal to the first set duration;

[0117] The second indoor ambient temperature is lower than the first set temperature and the first outdoor ambient temperature is higher than the second set temperature. The second indoor ambient temperature is the current indoor ambient temperature in the space where the air conditioner operates, and the first set temperature is lower than the second set temperature.

[0118] Specifically, the air conditioner can be preset with a preset temperature range and a preset humidity range. It determines whether to enter anti-condensation control based on a comparison between the first indoor ambient humidity and the preset humidity range, and determines whether to enter anti-condensation control based on a comparison between the second indoor ambient temperature and the first outdoor ambient temperature and the preset humidity range.

[0119] The first set temperature here is the minimum critical value of the preset temperature range, and the second set temperature is the maximum critical value of the preset temperature range. When both the second indoor ambient temperature and the first outdoor ambient temperature are outside the preset temperature range, it indicates that the air conditioner has a risk of condensation. At this time, step S10 is executed to make the air conditioner enter the anti-condensation control, thereby enabling the air conditioner to provide sufficient cooling capacity to ensure indoor cooling or dehumidification while preventing condensation on the heating module.

[0120] The first set humidity here is the maximum critical humidity of the preset humidity range. If the first indoor ambient temperature and humidity are greater than the first set humidity, it indicates that the indoor air humidity is too high. In this case, the air entering the air duct of the air conditioner for heat exchange is prone to condensation. At this time, step S10 is executed to put the air conditioner into anti-condensation control, thereby ensuring that the air conditioner provides sufficient cooling capacity to ensure indoor cooling or dehumidification while preventing condensation on the heating module.

[0121] When the air conditioner operates in cooling or dehumidifying mode for a duration greater than or equal to the first set time, it indicates that the air conditioner has adjusted the indoor environment to a sufficiently low temperature. At this time, step S10 is executed to put the air conditioner into anti-condensation control, thereby enabling the air conditioner to provide sufficient cooling capacity to ensure indoor cooling or dehumidification while preventing condensation on the heating module.

[0122] In this embodiment, based on the first target condition, the air conditioner can automatically enter the anti-condensation control stage to adapt to the actual working conditions, thereby enabling the air conditioner to provide sufficient cooling capacity to ensure indoor cooling or dehumidification while preventing condensation on the heating module.

[0123] Furthermore, in this embodiment, after the step of controlling the operation of the heating module according to the heating control parameters, the method further includes: when the air conditioner meets at least one sub-condition of the second target condition, controlling the heating module to turn off;

[0124] And / or, after the step of increasing the frequency of the compressor according to the frequency adjustment value when the heating module is turned on, the method further includes: when the air conditioner meets at least one sub-condition of the second target condition, controlling the heating module to turn off, and reducing the frequency of the compressor according to the frequency adjustment value;

[0125] The second objective condition includes the following sub-conditions:

[0126] Received a command to end cooling or dehumidification operation;

[0127] The humidity of the first indoor environment within the space where the air conditioner operates is less than the second set humidity.

[0128] The third indoor ambient temperature is greater than the third set temperature and the first outdoor ambient temperature is less than the fourth set temperature. The third indoor ambient temperature is the current indoor ambient temperature in the space where the air conditioner operates, and the third set temperature is less than the fourth set temperature.

[0129] Here, reducing the compressor frequency based on the frequency adjustment value specifically means restoring the compressor's operating frequency to the frequency before entering the anti-condensation control state.

[0130] The end command can be entered by the user according to their own needs.

[0131] The second set humidity can be the minimum threshold value of the preset humidity range mentioned above. If the first indoor ambient humidity is less than the second set humidity, it means that there is no longer a risk of condensation in the air inside the air conditioner duct, and the anti-condensation control can be turned off at this time.

[0132] The third set temperature can be the minimum critical temperature of the aforementioned preset temperature range, and the fourth set temperature can be the maximum critical temperature of the aforementioned preset temperature range.

[0133] In this embodiment, based on the second objective condition, the air conditioner can automatically exit the anti-condensation control stage to adapt to actual operating conditions and user needs. At this time, the heating module is shut off in time, so that the air conditioner can provide sufficient cooling capacity to ensure indoor cooling or dehumidification while preventing condensation on the heating module.

[0134] Furthermore, this invention also proposes a computer-readable storage medium storing a control program for an air conditioner. When the control program is executed by a processor, it implements the relevant steps of any of the above-described air conditioner control methods.
