PARALLEL MULTISTAGE HOT-WATER PUMP OPERATING ON PRINCIPLE OF EVAPORATION AND CONDENSATION OF WATER Russian patent published in 2002 - IPC

FIELD: mechanical engineering; thermal pumps. SUBSTANCE: steam formed in steam generating chamber under action of heat from combustion chamber passes through connecting steam pipe to provide discharging of water contained in pump chamber outside its limits in form of hot water through steam generating chamber, discharged water check valve, discharged water connecting channel, discharged water re-heat chambers, through outlet pipe and outlet discharge hole. At the same time, in pump chamber is fed to condensation chamber where it comes in contact with cold water which provides quick condensation of water and drop of pressure in chamber. Reduced pressure in condensation chamber provides suction of water through inlet suction hole, water suction channel and water suction check valve. Sucked-in water is fed to pump chamber through connecting suction pipe. EFFECT: improved heating, increased capacity. 6 dwg
