DEHUMIDIFIER
Document Type and Number:
WIPO Patent Application WO/2018/173120
Kind Code:
A1
Abstract:
This dehumidifier is provided with: a refrigerant circuit wherein a compressor, a condenser, an expansion device, and an evaporator are connected sequentially by piping; a blower for causing air to flow through an air passage which extends from a space to be dehumidified, passes through the evaporator and the condenser, and returns to the space to be dehumidified; an inlet humidity sensor provided at the inlet of the air passage; an evaporation temperature sensor for measuring the evaporation temperature of the evaporator; and a control unit. The control unit is configured such that, when the evaporation temperature is higher than the freezing temperature of water, the control unit controls the operation frequency of the compressor according to the difference between target hummidity and actually measured humidity.
