Abstract

A refrigeration cycle device includes a compressor, an upstream branch portion, a heating portion, a decompression portion, a bypass passage, a bypass flow adjustment portion, and a mixing portion. The mixing portion mixes a bypass side refrigerant flowing out from the bypass flow adjustment portion with a decompression-portion side refrigerant flowing out from the decompression portion, and causes the mixed refrigerant to flow to a suction port side of the compressor. The mixing portion mixes the bypass side refrigerant and the decompression-portion side refrigerant such that an enthalpy difference obtained by subtracting an enthalpy of an ideal homogeneously mixed refrigerant from an enthalpy of a suction side refrigerant actually sucked into the compressor is equal to or less than a predetermined reference value.
