Abstract

Provided is a compression apparatus for cooling multiple devices using a single fan with a small amount of electric power. An upper limit temperature, a first gain applied in a case in which a suction adjustment valve is opened, and a second gain applied in a case in which the suction adjustment valve is closed are set in advance for each of multiple temperature detectors provided at different locations of the compression apparatus; and, for each of the multiple temperature detectors, a difference between a detected value and the upper limit temperature is calculated, and a rotation speed of the fan is determined based on the smallest value in the differences, and the first gain or the second gain set for the temperature detector having the smallest difference.
