摘要
Oil is returned from the evaporator to the oil sump in a refrigeration chiller by directing the lubricant-liquid refrigerant mixture found in the chiller evaporator into heat exchange contact with relatively hotter system lubricant as such lubricant flows from the oil sump to the location of its use in the chiller's compressor. The oil flowing from the sump to the compressor rejects sufficient heat to the lubricant-liquid refrigerant mixture to induce the percolation thereof, such percolation being sufficiently energetic to cause slugs of the lubricant-liquid refrigerant mixture to be delivered from the location of heat exchange into the chiller's lubricant sump thereby effecting the return of oil from the evaporator for re-use in the compressor.
