Abstract: PROBLEM TO BE SOLVED: To reduce load on a compressor applied at the time of power being tuned on, when outdoor temperature and inside temperature of the refrigerator are high. SOLUTION: When both the temperature detected by a chamber-temperature sensor and the outdoor temperature are at least a predetermined temperature, (i.e., in the case power is turned on at uncooled time of both the outdoor and chamber temperatures being high), a flow-rate of refrigerant passing through a refrigerant flow-rate variation device 26 is controlled (forcedly decrease the refrigerant circulation amount) by the device 26 for a predetermined time, after the lapse of predetermined time from turning-on of the power). Thus, rapid discharge-pressure rise of the compressor 18 is restrained to reduce the load on the compressor 18, and its reliability can be enhanced (to prolong the service life of the compressor 18 is attained).
