Abstract
An oil-free compressor includes a compressor housing with a suction inlet and a discharge outlet, a compression mechanism and a liquid-vapor separation volume disposed within the compressor housing, a crankshaft. The compression mechanism has an inlet fluidly connected to the suction inlet and a discharge volume fluidly connected to the discharge outlet. The crankshaft is engaged with the compression mechanism. The liquid-vapor separation volume is configured to separate a mixed phase of working fluid into liquid working fluid and gaseous working fluid. The liquid working fluid is supplied to the bearing. A heating, ventilation, air conditioning, and refrigeration (HVACR) system includes a refrigerant circuit with an oil-free compressor, a condenser, one or more expanders, and an evaporator.
