FIELD: power supply systems.
SUBSTANCE: invention relates to power supply systems using renewable energy sources. Geothermal-carbon dioxide power complex comprises turbine with electric generator, working medium receiver connected to turbine outlet, compressor with heat removal, cooling heat exchanger and working medium accumulator. Carbon dioxide gas from production well of carbonic mineral water deposit is compressed in compressor with heat removal made in form of oil-free carbon-dioxide compressor, and then cooled in heat exchanger-cooler. Part of carbon dioxide gas is condensed in cooling heat exchanger by means of refrigerating machine, and part is mixed with carbon dioxide gas from turbine with electric generator and supplied to working medium receiver made in form of pressure geothermal well, where it is heated in underground geothermal header and from production geothermal well it is supplied to turbine to produce electric power and to provide it with oil-free carbon dioxide compressor, compressor of refrigerating machine, electric motors of water pumps and consumers.
EFFECT: higher economic efficiency of operation of geothermal-carbon dioxide power complex.
