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.
Claims8
An accumulator for use in an air conditioning system which circulates a mixture of refrigerant fluid and lubricating oil, comprising an outer case having inlet means for receiving said mixture, an inner case disposed within said outer case, and outlet means including an upstanding pipe disposed within said inner case for discharging a gaseous component of said refrigerant fluid while oil and a liquid component of said refrigerant fluid collect outside of said pipe, an inner space being defined between said pipe and said inner case, and an outer space being defined between said inner and outer cases, at least said oil collecting in said inner space, and at least said liquid refrigerant collecting in said outer space, said inner case including at least one oil-return hole, and said pipe including at least one oil-return hole.
