Abstract: A vapor cycle compressor includes a controller section, a drive section in communication with the controller section, and a compression section operatively engaged with the drive section. The compression section includes a first compression stage and a return channel assembly downstream of the first compression stage. The return channel vane assembly includes return channel vanes that are configured to adjust their angle of orientation. The compression section also includes a second compression stage downstream of the return channel vane assembly, wherein inlet guide vanes are absent between the return channel vane assembly and the second compression stage.

Abstract: The disclosed technology generally relates to a compressor housing that includes a main housing portion and an end housing portion. The main housing portion is configured to house a compressor motor and an inlet housing. The inlet housing is configured to receive vapor refrigerant downstream of the compressor motor. The main housing portion and the end housing portion are configured to interface at a mating surface of the respective housing portions and define a volume. The end housing portion includes a sensor cavity extending into the volume toward an opening of the inlet housing.

Abstract: A vapor cycle compressor includes a motor section and a compression section operatively engaged with the motor section. A refrigerant path is in the motor section and in the compression section. The refrigerant path includes: a compression refrigerant path, for a single phase compression refrigerant, in the compression section; an inner rotor shaft refrigerant path, for a single phase inner rotor shaft refrigerant, in the compression section and in the motor section; and a stator refrigerant path, for a two phase stator refrigerant, in the motor section.
