Abstract

A working fluid circuit includes a compressor (10), an oil sump (56), and an oil injection system. The compressor compresses working fluid into a compressed working fluid. The oil injection system has an oil pathway that is connected to the oil sump and to a suction pathway of the compressor. The oil pathway injects the oil from the oil sump into the suction pathway to cool the working fluid in the suction pathway. A method of controlling a working fluid circuit includes suctioning working fluid into a compressor, compressing the working fluid, and discharging the working fluid from the compressor. The method also includes separating oil from the working fluid and supplying and injecting, via an oil pathway, the oil into a suction pathway of the compressor. Gaseous refrigerant dissolved in the oil is liberated from the oil to provide cooling to the working fluid in the suction pathway.
