Title:
OPERATION METHOD OF REFRIGERATOR
Document Type and Number:
Japanese Patent JP2018076991
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigerator which can surely perform defrosting of a cooling part by a defrosting heater even in the case where an ambient temperature surrounding the refrigerator is low, which can lower a refrigerant pressure in a refrigeration circuit even in the case where the ambient temperature is high, which can deal with a compressor whose starting torque is small, and which has suppressed manufacturing cost and power consumption cost low.SOLUTION: A refrigerator 10 comprises: a compressor 32 for compressing a refrigerant; a condenser 34 for condensing the refrigerant from the compressor 32; expansion means 36 for expanding the volume of the refrigerant from the condenser 34; an evaporator 18 for evaporating the refrigerant from the expansion means 36; an article storage chamber 14 cooled by the evaporator 18; a defrosting heater 22 for removing the frost which has grown in the evaporator 18; and a defrosting completion detection sensor 24 for detecting the completion of defrosting in the evaporator 18 by the defrosting heater 22. The defrosting completion detection temperature by the defrosting completion detection sensor 24 is varied according to an ambient temperature.SELECTED DRAWING: Figure 4
