COOL/WARM AIR DRYING SYSTEM USING HEAT PUMP

摘要

The present invention relates to a cool/warm air drying system using a heat pump, including a drying chamber for storing an object to be dried therein; a body having an air circulation path communicating with the drying chamber to circulate the air in the drying chamber; and a drying unit installed in the air circulation path to dry the air in the drying chamber. The drying unit has an evaporator installed in the air circulation path to evaporate a refrigerant flowing therein so that the air fed in the air circulation path is cooled, a compressor connected to the evaporator by a first connection pipe to compress the refrigerant, a main condenser installed in the air circulation path and connected to the compressor by a second connection pipe to condense the refrigerant compressed by the compressor, thereby heating the air passing the air circulation path, and a throttle valve provided between the main condenser and the evaporator by third and fourth connection pipes to throttle the refrigerant condensed by the main condenser. Therefore, since the air in the drying chamber storing the object to be dried is cooled by the drying unit, and then is heated, the air is dehumidified to improve the drying efficiency of the object.;COPYRIGHT KIPO 2014
