Abstract:

Oil separation for a horizontal refrigeration screw compressor is achieved in a series of steps which achieves nearly oil-free refrigerant gas. The refrigerant is discharged from the compressor into a generally cylindrical shell which is divided into three chambers. A generally horizontal, but slightly tilted, divider plate unequally divides the cylindrical shell into two chambers for the greater portion of the cylindrical shell. A cylindrical chamber at the end of the cylindrical shell provides fluid communication between the other two chambers. The compressor discharge is located in the lower and larger chamber which is a segment of a circle portion which also contains the oil sump. A discharge deflector turns the compressor discharge flow at least 90. degree. , but as much as 135. degree.
