A compressor for air conditioning systems has an oil separator from which a small amount of compressed fluid is directed back to the compressor for cooling

摘要

The compressor (1) draws condensed refrigerant (3) to compress the refrigerant and deliver it to an oil separator (7) and return through the cooling system (9). A small quantity of fluid is bled off (11) to be cooled by the returning fluid (21) in a heat exchanger (17) and to cool the compressor (13).
