REMOVING DEVICE FOR DEFROSTING HEAT AND CONTROLLING METHOD THEREFOR

摘要

PURPOSE:To further stabilize an internal temperature in a freezing refrigerator and enhance its cooling efficiency. CONSTITUTION:A suction duct 15 and an open air suction fan 7 are installed to an evaporator unit 3 of a freezing refrigerator so as to take in an open air where a temperature sensor 9 is installed to the suction duct 15 and an evaporator 4. An on/off valve is installed to a flow passage where no damper is mounted in an internal cooled air flow passage so as to prevent the penetration of hot heat after the removal of frost.
