UNIT COOLER OF COLD STORAGE HOUSE FOR HIGH AND LOW RELATIVE HUMIDITY

摘要

A unit cooler for cold storage house combined with humidifier is provided to control a relative humidity within a range of 80 to 93% so that the cooler can be used for storing crops in high and low humidity by forming many refrigerant pipes and installing electronic valves each pipe. A unit cooler for cold storage house combined with humidifier comprises: an evaporator including a plurality of refrigerant tanks, pipes(121) and heat-exchanging fins provided between the pipes; a blower(111) provided at the front or rear surface of the evaporator for blowing air so that ambient air pass between the heat-exchanging fins of the evaporator; a heat transfer area controller(122). The refrigerant tanks and pipes are divided into several layers. The heat transfer area controller controls a relative humidity of the cold storage house by controlling the heat transfer area for the refrigerant tanks and pipes. The heat transfer area controller is a switch controlling passing of the refrigerant, and is a solenoid valve attached to each layer of the refrigerant tanks and pipes.
