Abstract

A refrigeration cycle device that performs injection in a compressor, and that is equipped with: a flow volume adjuster that adjusts the injection amount of a refrigerant flowing into the compressor from an injection pipe; and a control device that controls the degree of opening of the flow volume adjuster. The control device controls the degree of opening of the flow volume adjuster such that the degree of dryness is 1 or greater at a convergence section where the refrigerant drawn in from the intake side of the compressor and the refrigerant supplied from the injection pipe converge.
