Abstract

A compressor of a refrigeration cycle device includes an electric motor unit and a compression mechanism unit in a sealed container. The electric motor unit and the compression mechanism unit are coupled by a shaft. The compression mechanism unit includes a cylinder, a piston disposed in the cylinder, and a vane that partitions an inside of the cylinder. A shaft includes an eccentric portion. In the refrigeration cycle device, a vane groove in which the vane is disposed is formed in the cylinder. The eccentric portion is disposed in the cylinder. The piston is fitted to the eccentric portion. The vane operates without being separated from the piston. The controller controls the decompressor such that a degree of superheating in a case where the rotation speed of the compressor is in a low rotation speed band is smaller than a degree of superheating in a case where the rotation speed of the compressor is in a high rotation speed band.
