[0035] Figure 1 This is a schematic diagram of a method for controlling an air conditioner provided in an embodiment of this disclosure; combined with Figure 1 As shown, optionally, embodiments of this disclosure provide a method for controlling an air conditioner, comprising:

[0036] S11, the air conditioner obtains the indoor humidity, mixed air humidity, and mixed air temperature of the room where the air conditioner is located.

[0037] S12, the air conditioner determines the actual humidity content based on the indoor humidity where the air conditioner is located.

[0038] S13, the air conditioner determines the humidity content of the air to be treated based on the mixed air humidity.

[0039] S14, the air conditioner controls its operation based on the actual humidity content, the humidity content of the air to be treated, and the mixed air temperature.

[0040] In the scheme, a humidity sensor is arranged in the indoor space where the air conditioner is located, and the humidity sensor is used to detect the indoor humidity where the air conditioner is located. The mixed air humidity sensor and the mixed air temperature sensor are usually arranged in the air mixing section of the air conditioner. The mixed air section refers to the area where the fresh air and the return air are fully mixed, and the temperature and humidity at this point can accurately reflect the temperature and humidity state of the mixed indoor and outdoor air. In this way, the air conditioner can obtain the indoor humidity where the air conditioner is located through the humidity sensor arranged in the indoor space where the air conditioner is located, and obtain the mixed air humidity and the mixed air temperature through the mixed air humidity sensor and the mixed air temperature sensor arranged in the air mixing section of the air conditioner. With this scheme, the indoor humidity where the air conditioner is located, the mixed air humidity, and the mixed air temperature can be accurately obtained.

[0041] Optionally, the air conditioner can calculate the actual moisture content according to the indoor humidity where the air conditioner is located. Specifically, the actual moisture content can be calculated based on the ideal gas state equation to ensure the accuracy of the data.

[0042] Optionally, the air conditioner can determine the moisture content of the air to be treated according to the mixed air humidity. In this way, the moisture content of the air to be treated can be accurately calculated based on the mixed air humidity, ensuring the accuracy of the data.

[0043] Further, after the air conditioner determines the actual moisture content and the moisture content of the air to be treated, the air conditioner can control the operation of the air conditioner in combination with the actual moisture content, the moisture content of the air to be treated, and the mixed air temperature. Specifically, the air conditioner controls the operation of the air conditioner according to the actual moisture content, the moisture content of the air to be treated, and the mixed air temperature, including: the air conditioner determines the target dehumidification mode of the air conditioner according to the actual moisture content, the moisture content of the air to be treated, and the mixed air temperature. The air conditioner controls the air conditioner to operate in the target dehumidification mode. The target dehumidification mode includes a cooling dehumidification mode, a heating dehumidification mode, and a constant temperature dehumidification mode.

[0044] Optionally, the air conditioner can also collect the coil temperature through the temperature sensor arranged on the heat exchanger of the indoor unit, and start the cooling dehumidification mode when the coil temperature is equal to the sum of the dew point temperature corresponding to the set temperature and humidity and 3℃. Here, the minimum coil temperature can be set to 5℃, and the cooling dehumidification mode refers to the dehumidification operation of the air conditioner indoor heat exchanger, which includes the heating part heat exchanger (reheating section heat exchanger) and the refrigeration part heat exchanger (dehumidification section heat exchanger).

[0045] Optionally, the air conditioner starting the heating dehumidification mode includes:

[0046] The air conditioner sets the target coil temperature of the dehumidification section heat exchanger, and the target coil temperature is equal to the difference between the dew point temperature corresponding to the set temperature and humidity and 3℃, while ensuring that the temperature is not lower than the minimum limit temperature 5℃. Specifically, the dehumidification function can be realized by controlling the operation of the dehumidification section heat exchanger through the dehumidification valve.

[0047] The air conditioner sets the target coil temperature of the reheat section heat exchanger, which is equal to the sum of the current mixed air temperature and 4°C. Specifically, the operation of the reheat section heat exchanger can be controlled by adjusting the speed or working state of the outdoor fan to achieve the heating function.

[0048] The air conditioner turns on the electric heating device and keeps it in a continuous working state. Among them, the output power of the electric heating can be adjusted in real time by monitoring the outlet air temperature to ensure effective adjustment of indoor temperature and humidity.

[0049] In this way, during the operation of the temperature and humidity rising mode, the target coil temperatures of the dehumidification section heat exchanger and the reheat section heat exchanger, as well as the output power of the electric heating, can be dynamically adjusted according to the actual needs of the indoor environment, to achieve more accurate temperature and humidity control.

[0050] Optionally, the air conditioner starts the constant temperature dehumidification mode, which includes:

[0051] The air conditioner sets the target coil temperature of the dehumidification section heat exchanger, which is equal to the difference between the dew point temperature corresponding to the set temperature and humidity and 3°C, while ensuring that the temperature is not lower than the minimum limit temperature 5°C. Specifically, the operation of the dehumidification section heat exchanger can be controlled by the dehumidification valve to achieve the dehumidification function, and the dehumidification amount can be dynamically adjusted according to the change of indoor humidity.

[0052] The air conditioner sets the target coil temperature of the reheat section heat exchanger, which is calculated according to the indoor set temperature, the outlet air temperature and the temperature difference between them. Among them, the target coil temperature = set temperature + 3°C - (outlet air temperature - set temperature). Specifically, the operation of the reheat section heat exchanger can be controlled by adjusting the speed or working state of the outdoor fan to achieve the heating function, and the heating amount can be dynamically adjusted according to the change of indoor temperature.

[0053] The air conditioner dynamically determines the opening, closing or adjustment of the heating frequency of the electric heating device according to the indoor temperature and humidity conditions, the performance of the reheat section heat exchanger and the preset judgment conditions. Optionally, when the reheat section heat exchanger cannot meet the indoor temperature requirement or needs to quickly increase the indoor temperature, the electric heating device is turned on and its output power is adjusted as needed. When the indoor temperature approaches or reaches the set value and the heating part is sufficient to maintain, the air conditioner closes the electric heating device to save energy.

[0054] In this way, during the operation of the constant temperature dehumidification mode, the indoor temperature and humidity, outlet air temperature and other key parameters can be continuously monitored, and the working state of the dehumidification section heat exchanger, the reheat section heat exchanger and the electric heating device can be adjusted in real time according to the monitoring results, to ensure that the indoor temperature and humidity remain within the preset range.

[0055] The method for controlling an air conditioner provided in the embodiment of the present disclosure can accurately evaluate the humidity state and its change trend of the current indoor environment by using the actual moisture content and the moisture content of the air to be treated. The air conditioner is accurately controlled by using the actual moisture content, the moisture content of the air to be treated and the mixed air temperature, thereby improving the accuracy of dehumidification and the energy efficiency ratio and meeting the user's comfort requirement for the indoor environment.

[0056] Figure 2 is another schematic diagram of a method for controlling an air conditioner provided in the embodiment of the present disclosure; in combination with Figure 2 as shown, optionally, S14, the air conditioner controls the air conditioner to run according to the actual moisture content, the moisture content of the air to be treated and the mixed air temperature, including:

[0057] S21, the air conditioner determines the target dehumidification mode of the air conditioner according to the actual moisture content, the moisture content of the air to be treated and the mixed air temperature.

[0058] S22, the air conditioner controls the air conditioner to run in the target dehumidification mode.

[0059] In this scheme, the air conditioner determines the target dehumidification mode of the air conditioner according to the actual moisture content, the moisture content of the air to be treated and the mixed air temperature, including: in the case that the actual moisture content is greater than or equal to the first target moisture content, the moisture content of the air to be treated is greater than or equal to the second target moisture content, and the mixed air temperature is greater than or equal to the first target set temperature, the air conditioner determines that the target dehumidification mode of the air conditioner is the cooling dehumidification mode. In the case that the actual moisture content is greater than or equal to the first target moisture content, the moisture content of the air to be treated is greater than or equal to the second target moisture content, and the mixed air temperature is greater than or equal to the second target set temperature, the air conditioner determines that the target dehumidification mode of the air conditioner is the heating dehumidification mode. In the case that the actual moisture content is greater than or equal to the first target moisture content, the moisture content of the air to be treated is greater than or equal to the second target moisture content, and the mixed air temperature is in the target temperature range, the air conditioner determines that the target dehumidification mode of the air conditioner is the constant temperature dehumidification mode. With this scheme, the target dehumidification mode can be accurately determined in combination with the actual moisture content, the moisture content of the air to be treated and the mixed air temperature.

[0060] Further, in the case that the air conditioner controls the air conditioner to execute the target dehumidification mode, the accuracy of dehumidification and the energy efficiency ratio are improved, and the user's comfort requirement for the indoor environment is met.

[0061] Optionally, S21, the air conditioner determines the target dehumidification mode of the air conditioner according to the actual moisture content, the moisture content of the air to be treated and the mixed air temperature, including:

[0062] In the case that the actual moisture content is greater than or equal to the first target moisture content, the moisture content of the air to be treated is greater than or equal to the second target moisture content, and the mixed air temperature is greater than or equal to the first target set temperature, the air conditioner determines that the target dehumidification mode of the air conditioner is the cooling dehumidification mode. Alternatively,

[0063] In the case that the actual moisture content is greater than or equal to the first target moisture content, the air to be treated has a moisture content greater than or equal to the second target moisture content, and the mixed air temperature is greater than or equal to the second target set temperature, the air conditioner determines that the target dehumidification mode of the air conditioner is the temperature-increasing dehumidification mode. Alternatively,

[0064] In the case that the actual moisture content is greater than or equal to the first target moisture content, the air to be treated has a moisture content greater than or equal to the second target moisture content, and the mixed air temperature is within the target temperature range, the air conditioner determines that the target dehumidification mode of the air conditioner is the constant-temperature dehumidification mode.

[0065] In this scheme, the first target moisture content can be a target moisture content preset by the user. The second target moisture content = the first target moisture content + 1 g / kg. The first target set temperature = the set temperature + 4℃. Here, the set temperature is a target value of the indoor temperature that the user expects the air conditioner to reach and is stored in the air conditioner in advance by the user. In this way, in the case that the actual moisture content is greater than or equal to the first target moisture content, the air to be treated has a moisture content greater than or equal to the second target moisture content, and the mixed air temperature is greater than or equal to the first target set temperature, the air conditioner determines that the target dehumidification mode of the air conditioner is the temperature-decreasing dehumidification mode. With this scheme, the target dehumidification mode of the air conditioner can be determined to be the temperature-decreasing dehumidification mode in the case that the actual moisture content, the air to be treated, and the mixed air temperature meet the corresponding conditions.

[0066] In this scheme, the first target moisture content can be a target moisture content preset by the user. The second target moisture content = the first target moisture content + 1 g / kg. The second target set temperature = the set temperature - 4℃. Here, the set temperature is a target value of the indoor temperature that the user expects the air conditioner to reach and is stored in the air conditioner in advance by the user. In this way, in the case that the actual moisture content is greater than or equal to the first target moisture content, the air to be treated has a moisture content greater than or equal to the second target moisture content, and the mixed air temperature is greater than or equal to the second target set temperature, the air conditioner determines that the target dehumidification mode of the air conditioner is the temperature-increasing dehumidification mode. With this scheme, the target dehumidification mode of the air conditioner can be determined to be the temperature-increasing dehumidification mode in the case that the actual moisture content, the air to be treated, and the mixed air temperature meet the corresponding conditions.

[0067] In the scheme, the first target humidity content can be a target humidity content pre-set by the user. The second target humidity content = the first target humidity content + 1 g / kg. The target temperature range is [set temperature - 4℃, set temperature + 4℃]. Here, the set temperature is a target value of indoor temperature that the user expects the air conditioner to reach and is pre-stored in the air conditioner by the user. In this way, in the case that the actual humidity content is greater than or equal to the first target humidity content, the air to be treated humidity content is greater than or equal to the second target humidity content, and the mixed air temperature is in the target temperature range, the air conditioner determines that the target dehumidification mode of the air conditioner is the constant temperature dehumidification mode. With this scheme, the target dehumidification mode of the air conditioner can be determined as the constant temperature dehumidification mode in the case that the actual humidity content, the air to be treated humidity content, and the mixed air temperature meet the corresponding conditions.

[0068] In an optimized scheme, the detection period of the actual humidity content, the air to be treated humidity content, and the mixed air temperature can also be set. For example, the detection and determination of the actual humidity content, the air to be treated humidity content, and the mixed air temperature can be performed every 30 minutes, so as to adjust the target dehumidification mode of the air conditioner in real time.

[0069] Optionally, in S12, the air conditioner determines the actual humidity content according to the indoor humidity where the air conditioner is located, including:

[0070]

[0071] In the scheme, d1 is the actual humidity content, k is a set coefficient, φ1 is the indoor humidity where the air conditioner is located, Ps is the saturation pressure of water vapor, and P is the atmospheric pressure. Specifically, the value of k can be 622. With this scheme, the indoor humidity where the air conditioner is located can be substituted into the foregoing formula to obtain the actual humidity content, thereby providing an accurate data basis for the determination of the target dehumidification mode of the air conditioner.

[0072] Optionally, in S13, the air conditioner determines the air to be treated humidity content according to the mixed air humidity, including:

[0073]

[0074] In the scheme, d2 is the air to be treated humidity content, k is a set coefficient, φ2 is the mixed air humidity, Ps is the saturation pressure of water vapor, and P is the atmospheric pressure. Specifically, the value of k can be 622. With this scheme, the mixed air humidity can be substituted into the foregoing formula to obtain the air to be treated humidity content, thereby providing an accurate data basis for the determination of the target dehumidification mode of the air conditioner.

[0075] Figure 3 is another schematic diagram of a method for controlling an air conditioner provided by the embodiments of the present disclosure; in combination with Figure 3 As shown in the figure, optionally, the embodiments of the present disclosure provide another method for controlling an air conditioner, including:

[0076] S31, the air conditioner obtains the indoor temperature where the air conditioner is located.

[0077] S32, the air conditioner determines the control strategy of the air conditioner compressor based on the indoor temperature and / or actual humidity content of the room where the air conditioner is located.

[0078] S33, Air Conditioning Control: The air conditioner executes the control strategy of the air conditioning compressor.

[0079] In this solution, a temperature sensor is installed in the room where the air conditioner is located to detect the indoor temperature. This solution enables accurate acquisition of the indoor temperature.

[0080] Furthermore, the air conditioner determines the control strategy of the air conditioner compressor based on the indoor temperature and / or actual humidity content.

[0081] Optionally, when the air conditioner is operating in cooling and dehumidification mode, the air conditioner determines the control strategy of the air conditioner compressor based on the indoor temperature, including:

[0082] When the indoor temperature where the air conditioner is located is greater than or equal to the first temperature, the air conditioner determines that the control strategy for the air conditioner compressor is to control the air conditioner compressor according to the fifth operating level.

[0083] When the indoor temperature where the air conditioner is located is lower than the first temperature but greater than or equal to the second temperature, the air conditioner determines that the control strategy for the air conditioner compressor is to control the air conditioner compressor according to the fourth operating level.

[0084] When the indoor temperature where the air conditioner is located is lower than the second temperature but greater than or equal to the third temperature, the air conditioner determines that the control strategy for the air conditioner compressor is to control the air conditioner compressor according to the third operating setting.

[0085] When the indoor temperature where the air conditioner is located is lower than the third temperature but greater than or equal to the fourth temperature, the air conditioner determines that the control strategy for the air conditioner compressor is to control the air conditioner compressor according to the second operating level.

[0086] When the indoor temperature where the air conditioner is located is lower than the fourth temperature but higher than or equal to the fifth temperature, the air conditioner determines that the control strategy for the air conditioner compressor is to control the air conditioner compressor according to the first operating level.

[0087] Specifically, the compressor operating frequency at the fifth operating speed is greater than that at the fourth operating speed, which in turn is greater than that at the third operating speed, which is greater than that at the second operating speed, which is greater than that at the first operating speed. The target temperature is the user-preset comfort temperature; therefore, the first temperature = target temperature + 5℃, the second temperature = target temperature + 4℃, the third temperature = target temperature + 3℃, the fourth temperature = target temperature + 2℃, and the fifth temperature = target temperature + 1℃. This scheme allows for precise determination of the compressor control strategy in cooling and dehumidification modes, taking into account the indoor temperature.

[0088] Optionally, when the air conditioner is operating in cooling and dehumidification mode, the air conditioner determines the control strategy of the air conditioner compressor based on the actual moisture content, including:

[0089] When the actual moisture content is greater than or equal to the first moisture content, the air conditioner determines that the control strategy for the air conditioner compressor is to control the air conditioner compressor according to the fifth operating setting.

[0090] When the actual moisture content is less than the first moisture content but greater than or equal to the second moisture content, the air conditioner determines that the control strategy for the air conditioner compressor is to control the air conditioner compressor according to the fourth operating setting.

[0091] When the actual moisture content is less than the second moisture content but greater than or equal to the third moisture content, the air conditioner determines that the control strategy for the air conditioner compressor is to control the air conditioner compressor according to the third operating setting.

[0092] When the actual moisture content is less than the third moisture content but greater than or equal to the fourth moisture content, the air conditioner determines that the control strategy for the air conditioner compressor is to control the air conditioner compressor according to the second operating setting.

[0093] When the actual moisture content is less than the fourth moisture content but greater than or equal to the fifth moisture content, the air conditioner determines that the control strategy for the air conditioner compressor is to control the air conditioner compressor according to the first operating level.

[0094] The compressor operating frequency at the fifth operating speed is greater than that at the fourth operating speed, which is greater than that at the third operating speed, which is greater than that at the second operating speed, which is greater than that at the first operating speed. The target moisture content is the user-preset comfortable moisture content. Therefore, the first moisture content = target moisture content + 5g / kg, the second moisture content = target moisture content + 4g / kg, the third moisture content = target moisture content + 3g / kg, the fourth moisture content = target moisture content + 2g / kg, and the fifth moisture content = target moisture content + 1g / kg. This scheme allows for precise determination of the compressor control strategy under cooling and dehumidification modes based on the actual moisture content.

[0095] Optionally, when the air conditioner is operating in heating and dehumidification mode, the air conditioner determines the control strategy of the air conditioner compressor based on the indoor temperature, including:

[0096] When the indoor temperature where the air conditioner is located is greater than or equal to the sixth temperature, the air conditioner determines that the control strategy for the air conditioner compressor is to control the air conditioner compressor according to the fifth operating level.

[0097] When the indoor temperature where the air conditioner is located is lower than the sixth temperature but higher than or equal to the seventh temperature, the air conditioner determines that the control strategy for the air conditioner compressor is to control the air conditioner compressor according to the fourth operating level.

[0098] When the indoor temperature where the air conditioner is located is lower than the seventh temperature but higher than or equal to the eighth temperature, the air conditioner determines that the control strategy for the air conditioner compressor is to control the air conditioner compressor according to the third operating level.

[0099] When the indoor temperature where the air conditioner is located is lower than the eighth temperature but higher than or equal to the ninth temperature, the air conditioner determines that the control strategy for the air conditioner compressor is to control the air conditioner compressor according to the second operating level.

[0100] When the indoor temperature where the air conditioner is located is lower than the ninth temperature but higher than or equal to the tenth temperature, the air conditioner determines that the control strategy for the air conditioner compressor is to control the air conditioner compressor according to the first operating level.

[0101] Specifically, the compressor operating frequency at the fifth operating level is greater than that at the fourth operating level, then at the third operating level, then at the second operating level, and finally at the first operating level. The target temperature is the user-preset comfort temperature; therefore, the sixth temperature = target temperature - 5℃, the seventh temperature = target temperature - 4℃, the eighth temperature = target temperature - 3℃, the ninth temperature = target temperature - 2℃, and the tenth temperature = target temperature - 1℃. This scheme allows for precise determination of the compressor control strategy in the heating and dehumidification mode, taking into account the indoor temperature.

[0102] Optionally, when the air conditioner is operating in heating and dehumidification mode, the air conditioner determines the control strategy of the air conditioner compressor based on the actual moisture content, including:

[0103] When the actual moisture content is greater than or equal to the first moisture content, the air conditioner determines that the control strategy for the air conditioner compressor is to control the air conditioner compressor according to the fifth operating setting.

[0104] When the actual moisture content is less than the first moisture content but greater than or equal to the second moisture content, the air conditioner determines that the control strategy for the air conditioner compressor is to control the air conditioner compressor according to the fourth operating setting.

[0105] When the actual moisture content is less than the second moisture content but greater than or equal to the third moisture content, the air conditioner determines that the control strategy for the air conditioner compressor is to control the air conditioner compressor according to the third operating setting.

[0106] When the actual moisture content is less than the third moisture content but greater than or equal to the fourth moisture content, the air conditioner determines that the control strategy for the air conditioner compressor is to control the air conditioner compressor according to the second operating setting.

[0107] When the actual moisture content is less than the fourth moisture content but greater than or equal to the fifth moisture content, the air conditioner determines that the control strategy for the air conditioner compressor is to control the air conditioner compressor according to the first operating level.

[0108] The compressor operating frequency at the fifth operating speed is greater than that at the fourth operating speed, which is greater than that at the third operating speed, which is greater than that at the second operating speed, which is greater than that at the first operating speed. The target moisture content is the user-preset comfortable moisture content. Therefore, the first moisture content = target moisture content + 5g / kg, the second moisture content = target moisture content + 4g / kg, the third moisture content = target moisture content + 3g / kg, the fourth moisture content = target moisture content + 2g / kg, and the fifth moisture content = target moisture content + 1g / kg. This scheme allows for precise determination of the compressor control strategy under the heating and dehumidification mode, based on the actual moisture content.

[0109] In an optimized solution, when the air conditioner is operating in constant temperature and dehumidification mode, the operating level of the electric heating module is determined as follows:

[0110] The air conditioner obtains the indoor temperature where it is located.

[0111] The air conditioner determines the operating level of the electric heating module based on the indoor temperature.

[0112] Optionally, the air conditioner determines the operating level of the electric heating module based on the indoor temperature, including:

[0113] When the indoor temperature where the air conditioner is located is greater than or equal to the sixth temperature, the air conditioner determines the operating level of the electric heating module to be the fifth operating level.

[0114] When the indoor temperature where the air conditioner is located is lower than the sixth temperature but higher than or equal to the seventh temperature, the air conditioner determines the operating level of the electric heating module to be the fourth operating level.

[0115] When the indoor temperature where the air conditioner is located is lower than the seventh temperature but higher than or equal to the eighth temperature, the air conditioner determines the operating level of the electric heating module to be the third operating level.

[0116] When the indoor temperature where the air conditioner is located is lower than the eighth temperature but higher than or equal to the ninth temperature, the air conditioner determines the operating level of the electric heating module to be the second operating level.

[0117] When the indoor temperature where the air conditioner is located is lower than the ninth temperature but higher than or equal to the tenth temperature, the air conditioner determines the operating level of the electric heating module to be the first operating level.

[0118] The heating frequency at the fifth operating level is greater than that at the fourth operating level, which in turn is greater than that at the third operating level, which is greater than that at the second operating level, which is greater than that at the first operating level. The target temperature is the user-preset comfort temperature; therefore, the sixth temperature is the target temperature - 5℃, the seventh temperature is the target temperature - 4℃, the eighth temperature is the target temperature - 3℃, the ninth temperature is the target temperature - 2℃, and the tenth temperature is the target temperature - 1℃. This scheme allows for precise determination of the heating module's operating level in constant temperature dehumidification mode, taking into account the indoor temperature.

[0119] Figure 4 This is a schematic diagram of another method for controlling an air conditioner provided in this disclosure embodiment; combined with Figure 4 As shown, optionally, this disclosure provides another method for controlling an air conditioner, including:

[0120] S41, the air conditioner determines the humidity content of the air to be treated based on the mixed air humidity.

[0121] S42, when the difference between the humidity of the air to be treated and the target humidity is less than a set threshold, the air conditioning control starts the humidification device.

[0122] In this solution, the mixed air humidity can be incorporated into the specific algorithm using the aforementioned methods to determine the humidity content of the air to be treated. If the difference between the humidity content of the air to be treated and the target humidity content is less than a set threshold, the air conditioner is controlled to activate the humidification device. Here, the set threshold can be 1 g / kg. Specifically, controlling the air conditioner to activate the humidification device includes controlling the air conditioner to activate the humidification membrane. With this solution, humidification can be achieved through the humidification device installed inside the air conditioner.

[0123] Furthermore, to accurately determine when to stop the humidifier, the actual moisture content can be obtained. If the actual moisture content is greater than or equal to the sum of the target moisture content and a set threshold, and this condition persists for a first set duration, the humidifier is controlled to stop humidifying. The first set duration is 3 minutes. This method accurately determines when the humidifier will stop.

[0124] In an optimized approach, the termination time for the cooling and dehumidification mode can be determined as follows:

[0125] The air conditioner obtains the actual moisture content, the moisture content to be treated, and the mixed air temperature.

[0126] If the actual moisture content is less than or equal to the difference between the target moisture content and the set threshold for a continuous first set duration, the moisture content to be processed is less than or equal to the target moisture content for a continuous first set duration, and the mixed air temperature is less than the sum of the set temperature and the temperature threshold for a continuous first set duration, the air conditioner will stop executing the cooling and dehumidification mode. The temperature threshold can be 3°C, and the first set duration can be 3 minutes. This scheme achieves precise determination of when the cooling and dehumidification mode ends.

[0127] In a preferred embodiment, when the air conditioner is operating in constant temperature and dehumidification mode, the system controls the air conditioner to acquire the actual moisture content and the moisture content to be processed. If the actual moisture content remains less than or equal to the difference between the target moisture content and a set threshold for a first set duration, and the moisture content to be processed remains less than or equal to the target moisture content for the same first set duration, the air conditioner compressor is controlled to shut down. The set threshold can be 1 g / kg, and the first set duration can be 3 minutes. This solution meets the user's energy-saving control requirements for air conditioning.
