The corresponding adjustment ratio is 0.3; the third stage is
The corresponding adjustment ratio is 0; the fourth stage is
The corresponding adjustment ratio is 0.15; the fifth stage is

And a second rotational speed adjustment ratio
Then, the ratio is compared with that of the outdoor fanCurrent speed of rotation N0(i.e., adjusting the rotational speed of the front outdoor fan) to obtain a first rotational speed adjustment amount Δ N1And a second rotational speed adjustment amount DeltaN2Then adjusted by a first rotational speed Δ N1And a second rotational speed adjustment amount DeltaN2And adjusting the rotating speed of the outdoor fan.
In particular, if the current indoor ambient humidity

And then, the current indoor humidity is higher, and a high humidity control process is started, namely, the rotating speed of the outdoor fan is controlled to be increased, and the current running frequency of the compressor is controlled to be kept unchanged. Wherein the adjusted rotating speed of the outdoor fan
Because the rotational speed of outdoor fan risees for the evaporating temperature of indoor heat exchanger reduces, when evaporating temperature is less than the dew point temperature of indoor air, the moisture condensation in the air is appeared, thereby makes indoor humidity descend, in order to reach preset humidity range.
If the current indoor environment humidity
Less than the lower limit of the preset humidity range
And then, the current indoor humidity is low, and the low humidity control process is started, namely, the rotating speed of the outdoor fan is reduced and controlled, and the current running frequency of the compressor is controlled to be kept unchanged. Wherein the adjusted rotating speed of the outdoor fan
Because the rotating speed of the outdoor fan is reduced, the evaporation temperature of the indoor heat exchanger is increased, and the indoor heat exchanger is used indoorsThe heat exchanger side heat exchange is mainly sensible heat exchange, so that the latent heat ratio of the air conditioner is improved, the occupation ratio of latent heat in refrigerating capacity is reduced, and the reduction of dehumidification capacity is finally realized. In which the indoor relative humidity is increased because the indoor temperature is lowered without much change in the indoor absolute moisture content.
If the current indoor environment humidity
Greater than or equal to the lower limit value of the preset humidity range
And is less than or equal to the upper limit value of the preset humidity range
The rotating speed N of the outdoor fan is controlled without adjusting the rotating speed of the outdoor fan0Remain unchanged and do not adjust the operating frequency of the compressor.

Latent heat refers to the amount of heat absorbed or released per unit mass of a substance from one phase to another at isothermal and isobaric pressures. For example, when the current indoor ambient humidity
Less than the lower limit of the preset humidity range
During the time, reduce the conversion of refrigerant between gaseous state and liquid through reducing outdoor fan's rotational speed to reduce the occupation ratio of latent heat volume in the refrigeration capacity, finally realize the reduction of dehumidification volume, improved the relative humidity of room air, satisfied user comfort level demand.
