Abstract

A vehicular air conditioning system (10) includes a compressor (110) having a crank chamber (138), a suction chamber (120), and a discharge chamber (122). A refrigerant mixture includes carbon dioxide and oil. A conduit (13) connects the discharge chamber (122) of the compressor (110) directly with an oil separator (14) to route the refrigerant mixture directly to the oil separator (14). Only a restricted orifice (16) is provided between the oil separator (14) and the crank chamber (138) of the compressor (110) to throttle oil as it travels directly to the crank chamber (138) of the compressor (110).
