METHOD OF PRODUCTION OF COLD AND COMPRESSION REFRIGERATING MACHINE Russian patent published in 1997 - IPC

FIELD: refrigerating engineering. SUBSTANCE: when housing 1 of refrigerating machine rotates about horizontal axis, port 10 catches in turn portions of liquid working medium and working body. Gas portions of working body is compressed due to high density of working medium moving towards axis of spiral. Working body gives up heat to working medium heating it and cooling and liquefying itself. Liquefied working body enters pipe 11 through port 15 and then it flows to throttle 16. In evaporator 8 liquid working body is converted to gaseous state being heated from external source. Liquid working medium enters pipe 11 through port 14 and then it flows to heat exchanger 6. EFFECT: enhanced efficiency. 10 cl, 6 dwg
