Title:
Refrigerating device
Document Type and Number:
Japanese Patent JP6207602
Kind Code:
B2
Abstract:
A refrigerating device comprises: a refrigerant circuit in which a flammable refrigerant circulates and that is formed by coupling a compressor (1), a condenser (2), a liquid receiving container (3), an electromagnetic valve (4), a throttling device (5), and an evaporator (6); a pressure sensor (9) that detects the suction pressure on the intake side of the compressor (1); and a defrosting heater (7, 12) that defrosts the evaporator (6). The electromagnetic valve (4) is closed when starting to defrost the evaporator (6); the compressor (1) continues to operate until the suction pressure detected by the pressure sensor (9) is less than or equal to a prescribed value required to maintain safety when using a flammable refrigerant; and when the pressure is less than or equal to the prescribed value, the operation of the compressor (1) stops and the defrosting heater (7, 12) is supplied with current.
