And S24, when the angle of the air deflector is a first preset angle and the environmental humidity is greater than or equal to a preset second humidity threshold value, acquiring the operation wind shield of the air conditioning equipment.

Optionally, the manner of adjusting the wind gear may also be determined according to the magnitude of the ambient humidity exceeding the second humidity threshold, for example, if the current ambient humidity is 70%, exceeds the second humidity threshold by 5%, and the current operating wind gear is the first gear, the operating wind gear may be adjusted to the second gear; if the current environment humidity is 75%, exceeds the second humidity threshold value by 10%, and the current operation gear is the first gear, the operation gear can be directly adjusted to the third gear.
It should be noted that, if the current wind speed is the fifth speed with the maximum wind power, the air conditioning equipment is controlled to continue to operate in the fifth speed.
And S26, acquiring the temperature in the evaporator tube within a preset time.
During the adjustment of the operating damper of the air conditioning apparatus, the temperature in the evaporator tube of the air conditioning apparatus is continuously detected for a preset time (for example, 5 minutes).
And S27, controlling the operation state of the air conditioning equipment to be kept unchanged when the temperature in the evaporator tube is greater than or equal to a first temperature threshold value.
In the embodiment of the invention, a first temperature threshold is preset, the first temperature threshold is a critical temperature at which water vapor in air is condensed into water drops, when the operating wind level of the air conditioning equipment is adjusted, when the temperature in an evaporator tube is greater than or equal to the first temperature threshold, the characteristic that condensation is not easy to occur at the moment is shown, and further, the condensation is not easy to adhere to an air deflector, and the operating state of the air conditioning equipment is controlled to be kept unchanged.
Further, when the air conditioning apparatus is operated for a certain period of time (e.g., 10 minutes) while maintaining the current operation state, the ambient humidity is re-detected, and when the ambient humidity is less than the second humidity threshold value (e.g., 65%), and the duration of the ambient humidity being less than the second humidity threshold value exceeds a certain period of time (e.g., 10 minutes), the operation state of the air conditioning apparatus may be restored to the initially set operation state, i.e., the operation state when the operating windshield is not adjusted.
And S28, when the temperature in the evaporator tube is smaller than a first temperature threshold value, adjusting the frequency of the compressor so that the temperature in the evaporator tube is larger than or equal to the first temperature threshold value.
When the temperature in the evaporator tube is smaller than the first temperature threshold value, the characteristic is that condensation is likely to occur at the moment, and further the condensation is likely to be attached to the air deflector, the frequency of the compressor is adjusted, the adjustment mode can be that the frequency of the compressor is rapidly reduced, and the temperature of the evaporator can be increased by reducing the frequency of the compressor, so that the temperature of the evaporator can be increased to be larger than or equal to the first temperature threshold value.
And S29, controlling the running frequency of the compressor to be kept unchanged when the temperature in the evaporator tube reaches the target temperature.
After the frequency of the compressor is adjusted in S28, until the temperature in the evaporator tube reaches the target temperature, where the target temperature is the evaporator temperature greater than or equal to the first temperature threshold, the operation frequency of the compressor is controlled to maintain the operation frequency at the time when the evaporator temperature is currently greater than or equal to the first temperature threshold.
Further, when the operating frequency of the compressor of the air conditioning apparatus is kept operating at the operating frequency at which the evaporator temperature is currently made equal to or higher than the first temperature threshold value for a certain period of time (for example, 10 minutes), the ambient humidity is re-detected, and when the ambient humidity is less than the second humidity threshold value (for example, 65%) and the duration of the ambient humidity being less than the second humidity threshold value exceeds a certain period of time (for example, 10 minutes), the operating state of the air conditioning apparatus can be restored to the initially set operating state, that is, the operating state at which the operating frequency of the compressor is not adjusted.
In an alternative scheme of the embodiment of the present invention, an angle at which condensation is likely to occur on the air deflector is preset as a first preset angle, and when the angle at which condensation is likely to occur on the air deflector is the first preset angle and the ambient humidity is less than a second humidity threshold (for example, 65%), since the ambient humidity is low, it indicates that condensation is likely not to occur at this time, and the operation state of the air conditioning equipment may be controlled to remain unchanged.
S210, when the angle of the air deflector is a second preset angle and the environmental humidity is greater than or equal to a preset third humidity threshold value, adjusting the frequency of the compressor according to a preset rule so as to enable the temperature in an evaporator tube of the air conditioning equipment to be greater than or equal to the second temperature threshold value.
In the embodiment of the invention, the angle at which the air deflector is not easy to generate condensation is preset as a second preset angle, when the angle of the air deflector is at the second preset angle and the environmental humidity of the area where the indoor unit of the air conditioning equipment is located is greater than or equal to the third humidity threshold (for example, 75%), and, the environmental humidity should be less than the first humidity threshold (e.g., 80%) at this time, which indicates that condensation is relatively unlikely to occur at this time, the current operating damper can be maintained at this time, only the operating frequency of the compressor is adjusted, an adjustment rule is preset, the operating frequency of the compressor is adjusted according to a preset rule, which may be that the compressor operating frequency is decreased by B hertz every a minutes (e.g., by 100 hertz every 1 minute) until the temperature in the evaporator tubes is equal to or greater than a second temperature threshold, which may be 2 degrees celsius below the critical temperature at which water vapor in the air condenses into water droplets.
S211, when the temperature in the evaporator tube reaches the target temperature, controlling the running frequency of the compressor to be kept unchanged.
After the frequency of the compressor is adjusted in S210, until the temperature in the evaporator tube reaches the target temperature, where the target temperature is that the evaporator temperature is greater than or equal to the second temperature threshold, the operating frequency of the compressor is controlled to maintain the operating frequency at the time when the evaporator temperature is greater than or equal to the second temperature threshold.
Further, when the operating frequency of the compressor of the air conditioning apparatus is kept operating at the operating frequency at which the evaporator temperature is currently made equal to or higher than the second temperature threshold value for a certain period of time (for example, 10 minutes), the ambient humidity is re-detected, and when the ambient humidity is less than the third humidity threshold value (for example, 75%) and the duration of the ambient humidity being less than the third humidity threshold value exceeds a certain period of time (for example, 10 minutes), the operating state of the air conditioning apparatus can be restored to the initially set operating state, that is, the operating state at which the operating frequency of the compressor is not adjusted.
In an alternative example of the embodiment of the present invention, when the angle of the air deflector is the second preset angle and the ambient humidity is less than the third humidity threshold (for example, 75%), since the air deflector is at an angle at which condensation is not likely to occur, it is indicated that condensation is relatively not likely to occur at this time, and the operation state of the air conditioning equipment may be controlled to remain unchanged.
According to the control method of the air conditioning equipment provided by the embodiment of the invention, when the air conditioning equipment is in a refrigeration mode, the indoor environment humidity of an indoor unit of the air conditioning equipment and the angle information corresponding to an air deflector of the air conditioning equipment are obtained; determining a control strategy for the air conditioning equipment based on the ambient humidity and the air deflector angle; and controlling the air conditioning equipment based on the control strategy so that the condensation attached to the air deflector reaches a preset condition. According to the method, the operation wind shield and the compressor frequency of the air conditioning equipment can be controlled, the house damage and even potential safety hazards to users caused by condensation attached to the air deflector dropping can be prevented under the condition that the air outlet direction is not changed, and the user experience is improved.
