Under normal conditions, there will always be a small amount of oil that escapes a compressor’s crankcase and is circulated with the refrigerant throughout the system. It is for this reason that refrigerant oil and the refrigerant itself must be soluble in one another. It is the velocity of the circulated refrigerant that carries the oil back to the compressor’s crankcase. If the two were not soluble in one another, this phenomenon could not happen.
