THERMOCOMPRESSOR INSTALLATION Russian patent published in 1995 - IPC

FIELD: heat supply with use of thermocompressors. SUBSTANCE: used in thermocompressor circuit is carbon dioxide being in supercritical state after compression in compressor and each heater of both circuits of heat carriers is made in form of two-stage heat exchangers connected successively in compliance with flow direction of heat carriers. Discharge line of compressor is connected to heat exchanger of second stage of high-temperature circuit, after which it is separated into two branches. One branch is connected to heat exchanger of the first stage of same circuit, and the other is connected to heat exchanger of the second stage of low-temperature circuit. Both branches are connected at outlet of said heat exchanger and connected to heat exchanger of the first stage of low-temperature circuit. Besides, additionally installed may be partitions with shut-off devices between outlet of working medium of heat exchanger of the second stage of high-temperature circuit and inlet of heat exchanger of the second stage of low-temperature circuit, and between outlet of low-temperature heat carrier and inlet of high-temperature heat carrier, and between outlet of high-temperature heat carrier and inlet of low-temperature users. EFFECT: provision of users with two flows of heat carriers with different temperatures, reduced energy consumption of heat carriers with different temperatures, reduced energy consumption for compressor drive with simultaneous improvement of ecological safety. 2 cl, 3 dwg, 1 tbl
