TRIGENERATION CYCLE AND DEVICE THEREFOR Russian patent published in 2016 - IPC F01K25/04 

FIELD: machine building.

SUBSTANCE: present invention relates to heat power engineering and can be used as devices for simultaneous generation of heat, cold and electricity. Disclosed trigeneration cycle, as well as a device for its implementation can be used in energy generation during combined heat, electricity and cold generation. Composition of working fluid includes only one refrigerant which is vaporised and superheated by an external heat source. After evaporation and superheating of external heat source refrigerant vapour is expanded with production of mechanical power to a temperature above its condensation from external coolants. Said fluid is then condensed by an external coolant to a liquid state and then liquid refrigerant is throttled to lower pressure and temperature of coolant and its subsequent evaporation with production of cold. Refrigerant vapour is then formed with temperature below external coolant and then said vapour is compressed to pressure and temperature, allowing it to condense on external heat transfer with transfer of released heat energy. After condensation, liquid refrigerant is fed back to evaporator, whereby loop is closed.

EFFECT: use of trigeneration cycle and installation for its implementation will improve efficiency of generation of heat, electricity and cold with use of said heat of combustion of any carbon-containing fuel and fuel from renewable sources, geothermal energy, non-recycled low potential energy of large thermal power plants and cogeneration plants based on internal combustion engines.
