Abstract

A compressor unit includes a compressor body with a compression mechanism, and an accumulator. The compression mechanism includes a cylinder, a piston, and a blade. F×(h/I)×L≤19×P+128. F represents a value obtained by multiplying a weight of the piston and the blade by a square of the number of revolutions of the compressor body, and h represents a distance from a center of the piston in a thickness direction to a center of gravity of the compressor unit. I represents a moment of inertia around a center axis of the compressor unit passing through the center of gravity of the compressor unit. L represents a distance from an axis of an inlet pipe of the accumulator to the center of gravity of the compressor unit, and P represents a refrigeration apparatus rated capacity.
