THERMOCOMPRESSOR PLANT (MODIFICATIONS) Russian patent published in 2003 - IPC

FIELD: heat power engineering, in particular, heating and hot water supply of domestic, public and industrial buildings and objects with the use of steam thermocompressor plants. SUBSTANCE: the thermocompressor plant includes a contour formed by high-pressure and low-pressure lines filled with working medium-carbon dioxide (CO₂) containing a regenerative heat exchanger "high-pressure gas- low-pressure gas" evaporator including a contour a low-potential heat source, compressor, whose high-pressure line is connected by countercurrent flow and successively connected to the "gas-heating water" high-temperature and low- temperature heat exchangers, and the low-pressure line is connected to the low-pressure outlet of the regenerative heat exchanger. In the second modification the thermocompressor plant, in addition to the separator of the liquid phase of CO₂ from the gaseous phase of CO₂ is additionally provided with an expanding machine-turbo-pressure outlet of the regenerative heat exchanger, and the outlet is connected to the inlet of the gaseous phase of CO₂ of the separator of the liquid phase of CO₂, it is also additionally provided with a circulating pump of liquid CO₂, whose inlet is connected to the outlet of the liquid phase of CO₂ from separator of liquid phase, and the outlet of the circulating pump is connected to the evaporator inlet, the outlet of the evaporator gas-liquid mixture is connected to the gas cavity of the separator of the liquid phase of CO₂ from the gaseous phase. EFFECT: enhanced energy efficiency of heat transfer from the low- potential source to heated heating water (enhanced coefficient of transformation and efficiency of the thermocompressor plant, automatic maintaining of the preset optimal parameters of plant operation, enhanced durability of hot water supply heat exchangers, enhance, environmental safety of plant operation. 12 cl, 2 dwg
