However, in the cooling type dehumidifier, the indoor air is brought into contact with the evaporator so that the treated air from which the moisture is removed is deprived of heat and the temperature is lowered. Therefore, the temperature of the processing air supplied to the room is significantly lower than the room temperature, Not only the temperature is affected but also the temperature difference between the evaporator and the evaporator which maintains the dew point is not large when the ambient temperature is low so that the moisture contained in the room air can not be liquefied and the dehumidifying ability is lost.

Further, since the cooling type dehumidifier is a condition for dehumidifying the indoor air, the evaporator must be maintained in a cooling state below the dew point, so that the maintenance cost is increased by using excessive energy compared with the dehumidifying capacity during operation .

On the other hand, the dry type dehumidifier generally has a main body in which a regenerating side passage through which outdoor air passes and a processing side passage through which room air passes are partitioned by a partition wall and a main body which is rotatable in a direction perpendicular to the regenerating side and the processing side passage And a heater installed in the regeneration side passage for drying and regenerating the dehumidification rotor.
