HEAT PUMP ELECTRIC POWER SUPPLY PLANT Russian patent published in 2014 - IPC F25B9/08 

FIELD: engines and pumps.

SUBSTANCE: invention relates to heat engineering. Heat pump power supply plant with heterogeneous working medium composed of foam-like mix of neutral fluid and inert gas comprises circuits of working medium fluid and gas circulation with heating and cooling heat exchangers, controlled throttle, expander and adiabatic compressor with foam generator and vortex separator. Foam generator mixing screen of foam generator is connected to ejector compressor passive medium inlet. Ejector compressor active medium inlet nozzle is connected with hydraulic pump outlet. Said hydraulic pump inlet is connected with controlled throttle and hot heat exchanger of fluid circuit connected to vortex separator bottom fluid pipe. Vortex separator tangential pipe is connected to ejector compressor outlet diffuser via heat-isolated oven coil. Vortex separator top gas pipe is connected to recuperative heat exchanger first channel connected with expander inlet. Expander outlet is connected via cold heat exchanger and recuperative heat exchanger second channel with foam generator gas inlet. Foam generator fluid inlet is connected with controlled throttle. The latter is connected to hydraulic pump inlet. Hydraulic pump with low-rpm drive is articulated via overrunning clutch and reduction gear with expander and electric generator.

EFFECT: decreased weight and overall dimensions, higher efficiency.
