Step 2, judge whether the ambient humidity of humidity sensor detection is greater than the first preset value；If more than then continuing step
4, continue step 3 if being less than；
Step 3, the first fan operation, the second blower stop, and pass through the outlet air of crosswind mouth and lower air port return air；
Step 4, the second blower is opened, stops the first blower, passes through lower air port outlet air and crosswind mouth return air.
Above-mentioned dehumidification control method further include:
Step 5, judge whether the ambient humidity of humidity sensor detection is greater than the second preset value, second preset value is big
In the first preset value, if more than then continuing step 6, if being less than, continuing step 7；
Step 6, the windscreen of the second blower is improved, and continues return step 5 and monitors ambient humidity whether to be greater than second default
Value；
Step 7, the windscreen of the second blower is reduced, and return step 2 monitors whether ambient humidity is greater than the first preset value.
The ambient humidity that humidity sensor detects in the step 2 is the humidity in lower air port.
The ambient humidity that humidity sensor detects in the step 5 is the humidity of crosswind mouth.
Compared with prior art, the present invention by the basis of the air-cooled ducted air conditioner of existing air conditioner reversible outlet air technology under
It installs blower at air port additional, and humidity sensor is installed in the air port of air-cooled ducted air conditioner, and big according to the humidity that humidity sensor detects
Small operation and stopping controlling blower switches return air inlet and air outlet, goes out in dehumidified state from air port under crosswind mouth return air
Wind avoids the wind-force for directly blowing to human body excessive, while crosswind mouth can be reduced faster towards the region that room air has circulated
Indoor humidity.
