ROTARY VAPOR REFRIGERATING MACHINE Russian patent published in 2001 - IPC

FIELD: refrigerating engineering. SUBSTANCE: proposed machine includes evaporator and condenser rigidly interconnected by means of heat-insulating member. Heat of evaporation is transferred from evaporator to condenser by working medium at rotation. Evaporator mounted under condenser, condenser and heat-insulating member are cylindrical in shape for rotation around common central axis. Diameter of condenser exceeds diameter of evaporator by 10 to 12 times. Diameter of evaporator exceeds diameter of heat-insulating member by 1.5 to 2 times. Bottom of condenser is made in form of truncated cone at angle of inclination of 1.5 to 3 deg. for regular drain of working medium in form of condensate without transfer of heat of condensation into evaporator. Side walls of evaporator and condenser are finned externally. Condenser is provided radial plates. EFFECT: simplified construction of refrigerating machine; possibility of obtaining low temperature without additional consumption of power. 2 cl, 1 dwg
