ABSTRACT:
A compressor unit for use with a heat pump system wherein a motor-driven compressor is disposed within a casing which can be placed indoors or outdoors. Vapor from the suction side of the system is directed into and through the compressor, through an oil separator-muffler, and then into contact with liquid from the high side of the system, the liquid being directed onto a rotating disk to form a spray which contacts and thereby de-superheats the compressor discharge vapor. The de-superheated vapor then moves into and through the air gaps of the compressor motor in heat exchange relationship thereto where it is re-superheated. The re-superheated vapor then leaves the fan ports of the motor and enters the open top of a vertical standpipe which also receives the excess liquid collected in a trough surrounding the upper end bell of the motor. The liquid is entrained in the re-superheated vapor and moves therewith out of the casing toward the four-way valve and the condenser coil of the system.
