PROBLEM TO BE SOLVED: To provide a refrigerator with small noise suppressing gas column resonance generated in a space of a compressor interior in regard to noise of a refrigerator. SOLUTION: The refrigerator is provided with a sealed container 2, a motor element 3, a compression element 4 driven by the motor element 3 and having a gas suction opening 6 opened into the sealed container 2, a compressor 1 housing the motor element 3 and the compression element 4, a control means 7 for controlling drive of the motor element 3, a rotational frequency selecting means 8 for selecting a rotation frequency of the motor element 3 from a plurality of preset rotational frequencies 15, an evaporator 13, and an accumulator 14 adjacent to the evaporator 13. Noise can be reduced since the motor element 3 is driven at a rotational frequency with low gas column resonance selected in response to a intruding heat quantity load, and a pressure in the sealed container 2.
