THE HYBRID-TYPE PLANT FACTORY USING THE HEAT PUMP

摘要

The present invention relates to a hybrid-type plant factory using a heat pump. More specifically, a condenser connected to a compressor of a refrigeration cycle is disposed in a first chamber to generate heat, and an evaporator of the refrigeration cycle is disposed in a second chamber to absorb heat. Moreover, two suction ports and one discharge port are installed on the compressor, and a portion of refrigerant is passed through an auxiliary expansion valve on a front end of a main expansion valve disposed between the condenser and the evaporator to be supplied to the compressor, thereby supplying an economical composite-type plant factory while improving cooling ability without a high capacity of refrigerant.
