COMPRESSOR COOLING SYSTEM

摘要

A system may include a compressor, a heat exchanger, an expansion device, and first and second working fluid flow paths. The compressor may include a compression mechanism and a motor. The heat exchanger may receive compressed working fluid from the compressor. The expansion device may be disposed downstream of the heat exchanger. The first working fluid flow path may fluidly connect the heat exchanger and the expansion device. The second working fluid flow path may be disposed downstream of the heat exchanger and may fluidly connect the heat exchanger with the compressor. The second working fluid flow path may provide compressed working fluid to the compression mechanism and to the motor.

1. A system comprising:
a compressor including first and second inlets and an outlet; a first heat exchanger receiving compressed working fluid from said outlet of said compressor; an expansion device disposed downstream of said first heat exchanger; a first working fluid flow path fluidly connecting said first heat exchanger and said expansion device; a second working fluid flow path fluidly connecting said first heat exchanger with said first inlet of said compressor, said first inlet being fluidly isolated from a compression chamber of said compressor; a second heat exchanger receiving working fluid from said expansion device and providing working fluid to said second inlet of said compressor; and a pump disposed between said first heat exchanger and said expansion device, said pump including an inlet and first and second outlets, said first outlet fluidly connected to said first working fluid flow path, said second outlet fluidly connected to said second working fluid flow path.
