Title: REFRIGERATOR AND COOLING SYSTEM
Abstract:
A refrigerator equipped with a refrigeration cycle having at least a compressor (19), an evaporator (20), a main condenser (21), and a condensation prevention pipe (41). In addition, the refrigerator has a flow path switching valve (40) connected downstream from the main condenser (21), a condensation prevention pipe (41) connected downstream from the flow path switching valve (40), and a bypass (43) connected in parallel with the condensation prevention pipe (41). Furthermore, when the evaporator (20) is being defrosted the flow path switching valve (40) is fully closed during operation of the compressor (19). Thus, after residual refrigerant in the evaporator (20) and the condensation prevention pipe (41) has been recovered, the compressor (19) is stopped and the flow path switching valve (40) is opened on the bypass (43) side, thereby supplying recovered high-pressure refrigerant to the evaporator (20), and after a prescribed time, current is supplied to a defrosting heater.
