Abstract

In a refrigerant cycle apparatus which is operated at a supercritical pressure on a high-pressure side, for a purpose of maintaining or enhancing performances or reducing generation of clogging or a dimension of a capillary tube, a compressor has a first compression element, and a second compression element which compresses a refrigerant compressed by the first compression element, a gas phase refrigerant in an intermediate pressure receiver is sucked into the second compression element of the compressor, a liquid phase refrigerant in the intermediate pressure receiver is pressure reduced in a second pressure reducing device, and introduced into an evaporator, and the first pressure reducing device comprises a capillary tube on an upstream side of the refrigerant, and throttling means on a downstream side of the capillary tube.
