Abstract

In a refrigeration cycle device, a 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. In the refrigeration cycle device, a receiver that stores a part of a refrigerant flowing through the refrigerant pipe is provided in the refrigerant pipe, and a receiver internal volume of the receiver is made larger than a difference between a utilization-side internal volume of heat exchange of the utilization-side heat exchanger and a heat source-side internal volume of heat exchange of the heat source-side heat exchanger to reduce a liquid refrigerant sucked into the cylinder.
