Abstract

Provided is a compressor capable of suppressing disproportionation reaction of HFO refrigerant as much as possible. A compressor (1D) comprises: a housing (2D) in which a refrigerant flows; a rotary compression mechanism (6A) that is provided inside the housing (2D) and compresses the refrigerant; and an electric motor (5D) that is provided inside the housing (2D) and drives the rotary compression mechanism (6A). The refrigerant is an HFO refrigerant containing R1123 or R1132 (E) or a mixed refrigerant containing the HFO refrigerant, and a pressure of a motor space (S4) containing a winding (53D) of the electric motor (5D) is set to 6 MPa or less. The rotary compression mechanism (6A) sucks the refrigerant from the motor space (S4), compresses the refrigerant, and then discharges the refrigerant to the outside of the housing (2D).
