ABSTRACT:
Where a helical screw compressor gas or vapor working fluid is not too soluble in the compressor lubricant for compression process cooling, such lubricant after separation from the working fluid and cooled to as a low a temperature as possible and operating at as high a pressure as possible, is fed to an atomizing nozzle and injected into the inlet end of the compressor. This produces a cloud type blanket of cool atomized droplets uniformly dispersed within the suction vapor or gas allowing the highest possible rate of heat transfer to occur during the compression process and achieving the highest possible isothermal efficiency in a gas compression system or operation near vapor saturation values in a refrigeration vapor compression system while avoiding large hydraulic losses in the compressor. Working fluids such as helium, air, and ammonia may provide extremely high superheated gas or vapor at the compressor inlet.
