Title:
DEHUMIDIFIER AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2013/012043
Kind Code:
A1
Abstract:
A dehumidifier comprising a controller (32) which calculates the amount of intake air load to be supplied to a secondary side on the basis of the differential pressure of a differential pressure gauge (28) and controls the rotational speed of a suction rotor (12) which is rotated by a motor (20), and a temperature/humidity sensor (26) which detects the absolute temperature of the processing air at a position before the processing air passes through a processing area (36) of the suction rotor (12); the amount of recycled air is calculated on the basis of the absolute temperature of the processing air detected by the temperature/humidity sensor (26), the amount of intake air calculated by the controller (32), and a pre-set value for the intake dew point temperature, and, on the basis of the calculation result, the amount of recycled air is controlled by the controller (32).
