To provide a refrigerator appropriately determining balance between operation load and cooling capacity of the refrigerator and reducing waste electric power consumption by appropriately controlling rotational frequency of a compressor.
The refrigerator 100 includes: a refrigerating cycle having a cooler 3 and the compressor 4 with variable rotational frequency; a freezing compartment temperature sensor 13 for detecting the temperature of a freezing compartment 103; and a control device 2 for operating the compressor 4 when the detection temperature by the freezing compartment temperature sensor 13 exceeds starting temperature and stopping the operation of the compressor 4 when the detection temperature is below stop temperature. After first predetermined time passes after start of the compressor 4, when the detection temperature by the freezing compartment temperature sensor 13 is not lowered to the stop temperature, the control device 2 determines the operation load of the refrigerator 100. In accordance with the determination result of the operation load, the control device 2 determines rotational frequency of the compressor 4 and controls the compressor 4 so as to achieve the determined rotational frequency.
