PROBLEM TO BE SOLVED: To solve the problem of the temperature of a deep freezing chamber rising by an operation of a chilled gas circulating blower for the freezing chamber, due to rising of the temperature of a cooler for the freezing chamber by allowing a refrigerant of a high temperature in a cooler for a cold storage chamber to flow to the cooler for the freezing chamber cooled to a temperature below zero, when the blower is operated simultaneously upon operation of a compressor though the temperature of the cooler for the storage chamber is raised when the operation of the compressor is started in the so-called deep freezing and cold storage operation mode, in which the freezing chamber and the storage chamber are in cooling states in the refrigerator, in which the refrigerant compressed by the compressor and fed via a condenser flows from the cooler for the storage chamber to the cooler for the freezing chamber, in a deep freezing and cold storage operation mode. SOLUTION: In order to suppress adverse influence of high cooler temperature for the cold storage chamber to the cooler for the deep freezing chamber, at starting of deep freezing and cold storage operation mode, an operation controller for the refrigerator comprises a means for delaying the operation of the cold gas circulating blower for the cold storage chamber at a prescribed time from the start of the operation of the compressor for starting the compressor. |
