COOLING OF COMPRESSOR LUBRICANT IN A REFRIGERATION SYSTEM

摘要

Compressor lubricant in a screw compressor-based refrigeration system is cooled by directing the lubricant from the system oil separator (14) to an oil-cooling heat exchanger (46) disposed in the lower portion of the system condenser (16) where it is bathed in condensed system refrigerant. Parasitic capacity losses with respect to the compressor lubricant cooling process are thereby avoided.
