ABSTRACT:
A refrigerator having a control device is provided with a refrigerating cycle system constructed by connecting in series a compressor, a condensor, capillary tubes, a storage compartment evaporator and a freezing compartment evaporator. This control device comprises a first control circuit to forcefully cool the freezing compartment evaporator upon receipt of a first instruction signal, a second control circuit for removing the frost deposited on the freezing compartment evaporator upon receipt of a second instruction signal, and a preferential control circuit, which, in case an operation based on a preferentially issued instruction signal is taking place, and, during this interim, a delayed instruction is given, causes an operation based on the delayed instruction signal to be commenced only after the operation based on the preferential instruction signal is brought to an end.
