Abstract
An air conditioning system circulates a mixture of refrigerant fluid and lubricating oil. An accumulator is disposed upstream of a compressor to separate gaseous refrigerant from liquid refrigerant and oil. The accumulator includes an outer case, an inner case, an upstanding pipe, and a baffle plate disposed in the outer case and above the inner case. Gaseous refrigerant exits the accumulator through the pipe. Oil and possibly liquid refrigerant collect in the inner case around the pipe. Liquid refrigerant and possibly oil collect outside of the inner case. Each of the pipe and inner case include vertically spaced oil-return holes.
