High power of a compressor that compresses a mixed refrigerant containing at least 1,2-difluoroethylene is achieved. A compressor (100) employs an induction motor (70) as a motor that drives a compression unit (60) that compresses a mixed refrigerant containing at least 1,2-difluoroethylene, and thus, high power is enabled at comparatively low costs.

A stationary scroll plate for use in a scroll compressor is described. The stationary scroll plate comprises a base plate having a first side and a second side, wherein the second side opposes the first side; a spiral wrap formed at the first side of the base plate, wherein the spiral wrap is adapted to interact with a corresponding spiral wrap of an orbiting scroll plate to form a compression chamber; an injection channel formed within the base plate, the injection channel providing an injection path for injection of fluid into the compression chamber; a recess located at the second side; an insert placed within the recess, wherein the insert forms a cooling chamber within the recess; an inlet channel via which the cooling chamber is connected to the injection channel; and an outlet channel via which the cooling chamber is connected to the inside of the spiral wrap.
