PURPOSE:To maintain the cooling temperature constant by utilizing the heat generating unit of a refrigerator in a dehumidifier condensing and separating the moisture contained in the gas. CONSTITUTION:The condensed gas is evaporated by a refrigerator 4 and heat- exchanged with the gas sent through a gas inlet A. A moisture contained in the gas is condensed, and the dried gas is brought into contact with a temperature sensor 5 and sent out through a gas outlet B. A solenoid valve 7 is closed by a signal from the temperature sensor 5 when the temperature of the high- pressure gas is higher than the predetermined temperature, on the contrary the solenoid valve 7 is opened when it is lower. Accordingly, the gas can be cooled at the fixed temperature, and an electric heater or the like is not required.
