When at least one of a first condition that a set compressor rotational speed is equal to or less than a compressor rotational speed limit set in advance based on a predetermined noise regulation value and a second condition that a set fan rotational speed is equal to or less than a fan rotational speed limit set in advance based on the predetermined noise regulation value is not satisfied, a cooling device sets a corrected compressor rotational speed such that noise generated with actuation of a compressor and a fan reaches the predetermined noise regulation value or less, and sets a corrected fan rotational speed based on the corrected compressor rotational speed. The cooling device sets a lower value of the corrected fan rotational speed for a higher corrected compressor rotational speed.
