Abstract: A refrigerant compressor according to an exemplary aspect of the present disclosure includes, among other things, an impeller arranged in a main flow path and including a plurality of vanes. The impeller is configured to rotate about an axis. A channel is outside the main flow path. A first orifice fluidly couples the channel to the main flow path upstream of the vanes, and a second orifice fluidly couples the channel to the main flow path downstream of leading edges of the vanes.

Abstract: An electric compressor includes an electric motor including a rotor and stator and a shaft rotating with the rotor to drive a compressor impeller. Bearings support the shaft. A housing encloses the impeller shaft, the bearings and the electric motor, and a sensor for sensing a condition within the housing. A control for the electric motor receives information from the sensor indicative of the potential of migrated refrigerant when the electric motor is not running. The control is operable to actuate a countermeasure to deliver heat into the housing to boil off the migrated refrigerant. A method is also disclosed.

Abstract: A refrigerant compressor according to an exemplary aspect of the present disclosure includes, among other things, a first compression stage arranged in a main refrigerant flow path. The first compression stage is a mixed compression stage having both axial and radial components. The compressor further includes a second compression stage arranged in the main refrigerant flow path downstream of the first compression stage. The second compression stage is a radial compression stage.
