Method and device for obtaining electrical energy and cold energy using low-potential heat carriers

Abstract

The invention relates to alternative energy and mainly concerns the production of electricity and cold energy using the energy of atmospheric air. The essence of the invention is that in the method of obtaining electrical energy and cold energy using low-potential heat carriers, according to the invention, a special consumption circuit-block is additionally installed, in which the steam produced by the proposed method feeds the turbines that drive the compressors that compress the cold agent helium of the reverse energy cycle. The refrigerant of the working medium is condensed at different pressures and temperatures in each condensation stage, the steam leaving the heater must be heated to a minimum temperature of +1°C, using a closed heater-evaporator and open-air coiled tubes (coils) to ensure the receipt of electrical energy and cold energy directed to the desalination plant by freezing seawater; Using atmospheric air to generate directed electrical energy and cold energy, both heaters installed after the closed heater are fed with a steam-water mixture from the parabolic solar heater evaporator, and in the absence of sunlight, with gases from the combustion chamber. The essence of the invention is that in the device for obtaining electrical energy and cold energy using low-potential heat carriers, according to the invention, seven serpentine tubes are added to the four serpentine tubes, four of which are for heating the steam of the working medium entering the turbine of the corresponding consumption unit and three of which are for power unit, and the seven added serpentine tubes are for absorbing the compression energy of helium, To reduce the compression energy of helium, to compress helium going to the penultimate expander, the last start-up coil tube was designed to cool the helium entering the expander during the start-up of the device, reducing the start-up time of the device, and heating the closed evaporator-heater using the energy of the corresponding dried atmospheric air.
