Rotary compresser cooled by condensate injection - has lubricant in condensate with bleed off vaporised and applied to bearings

摘要

The rotary compressor is cooled by condensate injection and lubricated by the same condensate, containing dissolved lubricant, being vapourised and applied to the bearings and other points. The condensate is held in a tank. A pipe conveys this to the compressor for cooling purposes, being returned to the tank through a condenser. Another pipe conveys condensate from the tank, through a heat exchanger, an evaporator and into the compressor suction side. A third pipe is a bleed-off and the small amount of condensate mix is passed through the heat exchanger, for cooling, where the oil forms a mist suitable for lubrication.
