Oil separators return oil to which location in the compressor system?

Explanation:
Oil separators are used to keep lubrication where it’s most needed: in the compressor crankcase. When the compressor pushes out refrigerant vapor, it also carries oil. The oil separator captures that oil and routes it back to the crankcase so it can be recirculated with the refrigerant through the compressor. Returning oil to the crankcase prevents oil from riding back into the suction line or accumulating in the condenser or liquid line, which would disrupt lubrication and system performance. By restoring oil to the crankcase, the compressor maintains proper lubrication and oil levels, supporting reliable operation.
