ABSTRACT:
A refrigerant handling system that includes a compressor having an inlet and an outlet, a condenser for withdrawing heat from and at least partially condensing refrigerant passing therethrough, and a compressor oil separator connected between the compressor outlet and the condenser for separating oil from refrigerant passing to the condenser. The compressor oil separator takes the form of a closed canister having an open internal volume, a vapor inlet and a vapor outlet at an upper portion of the canister, and an oil drain at a lower portion of the canister. A refrigerant coil is mounted externally of the canister in heat exchange relationship with the canister sidewall. The vapor inlet, vapor outlet and refrigerant coil are connected in series between the compressor outlet and the condenser coil such that heat of refrigerant passing through the coil heats the canister internal volume to prevent condensation of refrigerant therein.
