HYBRID DRYING SYSTEM AND THEREOF CONTROL METHOD

摘要

PURPOSE: A hybrid dry system and a control method of a hybrid dry system are provided to improve the drying efficiency by executing the operation without the heating source by supplying the condensation heat of a condenser for cold air drying to the desiccant drying. CONSTITUTION: A hybrid dry system is composed of a drying room(DM), a compressor(101), a condenser(102), an expansion valve(105), an evaporator(106), a desiccant drier(303), a heat exchanger(302), and a control unit. The evaporator cools and dries the object by heat-exchanging the refrigerant passing the expansion valve and the air(RA) returned from the drying room. The desiccant drier is composed of an adsorption unit(3031) and a desorption unit(3032). The adsorption unit makes the cold air dried air passing the drier to the dried air(S.A). The desorption unit supplies the regenerative air heated with condensation heat as regenerative heat source. The heat exchanger collects the exhaust heat by heat-exchanging the outdoor air and the regenerative air. The control unit controls the cold air drying and the desiccant drying according to the humidity and temperature of the drying room.
