OIL RECOVERY FOR REFRIGERATION SYSTEM |
摘要 |
A refrigerant system includes a compressor having a flow of compressor lubricant therein, the compressor compressing a flow of vapor refrigerant therethrough. An evaporator is operably connected to the compressor and includes an environment to be cooled via a thermal energy exchange with a liquid refrigerant in the evaporator. A vaporizer is receptive of a first flow of compressor lubricant and refrigerant mixture from the evaporator having a first concentration of lubricant. The vaporizer uses a flow of compressed refrigerant to separate refrigerant from the first flow. A lubricant sump is receptive of a second flow of compressor lubricant and refrigerant mixture from the vaporizer having a second concentration of lubricant greater than the first concentration. A heat exchanger is receptive of a third flow from the sump and uses evaporator suction gas to cool the third flow, thereby increasing its viscosity before urging the third flow to the compressor. |
