ABSTRACT:
An oil separator for an air-cooled refrigeration system employing a screw compressor includes a U-shaped housing the bottom of which defines an oil sump and the upstanding leg portions of which are connected by flow splitting apparatus. The flow splitting apparatus divides and tangentially delivers portions of a mixture of compressed refrigerant gas received from the compressor, and in which oil is entrained, into the upper region of each leg portion. The tangential delivery of the mixture into the leg portions and the centrifugal force created thereby causes the entrained oil to be separated from the gas at two distinct locations in the separator. The separated oil drains along the inner walls of the leg portions of the separator to a common sump while the compressed refrigerant gas from which the oil has been separated exits each of the leg portions through open-ended conduits which extend into the leg portions.
