Abstract
An oil separation system for a refrigeration system having compressor, condenser-receiver and evaporator means, including an oil separator having a vortex separation chamber disposed in the refrigerant gas discharge line between the compressor means and condenser-receiver means, an oil reservoir for receiving oil from the separation chamber, and oil control means for maintaining a predetermined oil level in the compressor means including a pressure differential valve for regulating the flow of oil from the reservoir to the compressor means.
Claims15
An oil separation system for a refrigeration system having compressor, condenser-receiver and evaporator means, comprising an oil separator unit disposed in the refrigerant gas discharge line between said compressor means and said condenser-receiver means, said oil separator unit having a receiving chamber constructed and arranged to receive the refrigerant gas discharge from said compressor means and separate oil therefrom by centrifugal vortex action, means for precipitating vaporous separated oil into liquid form, oil reservoir means for storing liquid oil, and oil delivery means connecting said oil reservoir to said compressor means including oil level control means responsive to the compressor oil level and pressure differential valve means including means responsive to oil outlet pressure therefrom and compressor suction pressure acting in opposition for reducing the high side inlet oil pressure to a preselected low side pressure differential for regulating oil delivery to said oil level control means.
