ABSTRACT:
An improved motor driven centrifugal refrigerant compressor is disclosed having a housing enclosing a motor, control electronics and moving parts of the compressor, and a fluid pathway for circulating a mixture of low pressure refrigerant and a lubricant around the pathway, the pathway including a lubricant concentrator for coalescing the lubricant of the mixture to lubricate moving parts of the compressor and the pathway also including a convective heat transfer region to cool the motor and control electronics within the housing.
