Development of a twin screw expressor as a throttle valve replacement for water-cooled chillers.
Author(s) : BRASZ J. J., SMITH I. K., STOSIC N.
Summary
Power is recovered from the two-phase expansion process and used directly to recompress a portion of the vapour formed during the expansion. Both the expansion and recompression processes are carried out in a twin screw machine with only one pair of rotors. These rotate, without the need for timing gear, in a process-lubricated, totally sealed unit which the authors have called an "expressor". First test results indicate that the overall expansion-compression efficiency of the expressor is of the order of 55%.
