The oil collected in an oil separator is typically returned to which component?

Explanation:
Oil separators remove the oil that’s mixed with refrigerant vapor so it doesn’t keep circulating with the gas to the condenser. The lubricating oil needs to stay in the lubrication loop, which is within the compressor. If oil is allowed to stay with the refrigerant, the compressor can’t be properly lubricated, and oil can exit the system through the condenser or evaporator, harming heat transfer and efficiency. That’s why the oil collected in the oil separator is returned to the compressor (essentially feeding the compressor’s oil sump/crankcase) to be lubricated and recirculated.
