Dehumidifying principle of dehumidier:
When temperature is decreased to the temperature point of dew, water vapor in humid air will condensate. Dehumidier is
dehumidifying the air by using this principle.
During operation of the system, air will pass through evaporator and condenser in turn and then be discharged due to centrifugal
blade. When the air is passing through evaporator, refrigerant will absorb the heat in air to let its temperature decrease to the
temperature point of dew, water vapor in air will condensate. Condensate water comes into water tank through water tray, or is
discharged directly through drainage hose. The saturated low-temperature air passed through the evaporator will absorb the heat
when owing along the condenser, and then become the dry air. Under normal condition, the nearby air will become warm during
operation of dehumidier.
