Description

Dehumidifying device {DEHUMIDIFIER}

Embodiments of the present invention relate to a dehumidifying device.

Generally, a dehumidifier is used to maintain the service life of electronic appliances or clothes by properly controlling the humidity of the air in the surrounding atmosphere at the installation site to appropriately protect the electronic appliances or clothes in the installation site from moisture. The humidity of the air is controlled through contact between the evaporator in the dehumidifier, the refrigerant flowing in the condenser, and the air introduced into the dehumidifier.

In this case, the evaporator uses the heat of vaporization of the refrigerant to lower the temperature of air with the removal of moisture in the air, and the condenser uses the heat of liquefaction of the refrigerant to increase the temperature of the air. The dehumidifier is disclosed in Korean Patent Laid-Open Publication No. 10-2005-0086195 (published on Aug. 30, 2005). However, since the dehumidifier has a high frequency of use during the summer season, the dehumidifier continues to radiate heat to the installation site through the condenser during driving to increase the temperature of the installation site.

The increase in the temperature of the installation site increases the burden on the user of the dehumidifier due to the temperature of the summer season, thereby making it difficult for the user of the dehumidifier to live in the summer season.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a dehumidifier suitable for easily setting a desired temperature in a surrounding atmosphere of an installation place regardless of the season by appropriately adjusting the heat of liquefaction of the refrigerant in the condenser.
