The Oil Separator's function is to save energy and assist in making refrigeration and air conditioning systems operate more efficiently. Refrigerant and oil are present in all refrigeration systems. A certain amount of oil leaves the compressor crankcase with the refrigerant gas. The Oil Separator separates the oil from the refrigerant and returns it to the compressor crankcase before it can enter other components of the system. The less oil in circulation of a refrigeration system, the more refrigerant is available for cooling. When a system is operating efficiently, running time is reduced and operation costs lower.

The expansion valve removes pressure from the liquid refrigerant to allow expansion or change of state from a liquid to a vapor in the evaporator.
The high-pressure liquid refrigerant entering the expansion valve is quite warm. This may be verified by feeling the liquid line at its connection to the expansion valve. The liquid refrigerant leaving the expansion valve is quite cold. The orifice within the valve does not remove heat, but only reduces pres¬sure. Heat molecules contained in the liquid refrigerant are thus allowed to spread as the refrigerant moves out of the orifice. Under a greatly reduced pressure the liquid refrigerant is at its coldest as it leaves the expansion valve and enters the evaporator.
