<P>PROBLEM TO BE SOLVED: To provide an article cooling device which prevents liquid refrigerant from returning to reduce the service life of a compressor, while preventing the inside from being heated due to operation of an inside fan after power-saving operation. <P>SOLUTION: An operation control means 103 starts operations of an inverter compressor 71A and a constant speed compressor 71B when the power-saving operation ends. The rotation speed of each of internal fans 61A, 61B, 61C is made lower than that during normal operation of the inside fan from the time when the inverter compressor 71A and the constant speed compressor 71B start operations after the power-saving operation, to the time when an internal heat exchanger cooling capacity determination means 106 determines that the refrigerator in heat exchanger has a predetermined capacity on the basis of a detected temperature of each of the internal heat exchanger temperature sensors 101A, 101B, 101C or a compressor liquid refrigerant inflow determination means 107 determines that the liquid refrigerant is likely to flow into the inverter compressor 71A or the constant speed compressor 71B. <P>COPYRIGHT: (C)2013,JPO&INPIT |
