The invention relates to heat-power engineering, in particular to devices and methods for operation of energy production plants and can be used in different branches of national economy. A method for energy production includes heating of working medium in heat exchange zone till its evaporation, supply of working medium to working zone, cooling of working medium in heat exchange zone till its condensation and supply of condensate obtained for evaporation during which heating and cooling of working medium are carried out in cycles in one heat exchange zone at supply with alternation there of heat carrier with temperature difference of that one not higher than temperature of boiling point of working medium. The heating is performed to state of humid vapor, and in working zone with working medium that is supplied one performs displacement and filling of power carrier for cyclic supply of power carrier to local volumes with different pressure. A power unit has evaporation-condensation system connected to pipeline for supply of heat carrier, this consists of heat exchangers, and connected by pipelines to pumped propulsion system connected to unit for energy generation. The pumped propulsion system is arranged as at least two pumping reservoirs cavity of which is separated with movable elastic membrane to vapor chamber and hydraulic chamber connected through controlled valve installed in pipeline to two tanks connected through controlled valve to unit for energy production arranged as liquid turbine, and evaporation-condensate system is arranged as at least two heat exchangers each of which has connected to vapor chamber of pumping reservoir inner cavity and connected through controlled valve to pipeline for heat carrier supply outer cavity, at that the outer cavities of all the heat exchangers are connected to each other in counter-phase. Use of the method proposed and device for its realization provides increase of efficiency of installation at decrease of power consumption and improvement of operation conditions. |
