MACHINE FOR CONVERTING HEAT ENERGY INTO MECHANICAL (ELECTRIC) ENERGY Russian patent published in 2002 - IPC

FIELD: power engineering, transport, aviation, cosmonautics. SUBSTANCE: proposed machine converts low-grade heat of ambient medium into mechanical (electric) energy by using multicircuit thermodynamic cycles with mixing of heterogeneous clean gases. Gases are compressed in compressors in different circuits, heat of ambient medium is fed to gases in heat exchangers and then gases are mixed (it can be done many times) in gas ejectors to obtain mixtures with necessary thermal properties and thermodynamic parameters and then they are expanded in turbine to execute with subsequent separation of mixture into initial components. Invention makes it possible to use low-grade heat of ambient medium and get ecologically clean mechanical or electric energy as machine uses clean gases and no combustion of hydrocarbon fuels is present. EFFECT: provision of ecologically clean energy. 4 cl, 1 dwg
