TRIGENERATION SYSTEM Russian patent published in 2020 - IPC F25B30/00 F25B49/00 

FIELD: heat power engineering.

SUBSTANCE: invention relates to heat engineering, is intended for simultaneous generation of electric and heat energy, as well as cold in form of depleted water. Trigeneration plant comprises a steam compression heat pump, the condenser of which is technologically connected to the evaporative heat exchanger circuit of the absorption pump, wherein in the generator the heat is supplied by direct fuel combustion, the gas turbine unit, gas-water heat exchanger, absorption bromistolithium heat pump, electric drive compressor, regenerative heat exchanger, condenser, evaporator, overcooler, throttle, absorber, evaporative heat exchanger, generator furnace, cooler, air intake fan, axial compressor, combustion chamber, gas turbine, electric generator, circulation pump. Device is controlled from computerized control panel of electrically driven combined control valves with measuring units.

EFFECT: technical result is solving problem of heat recovery from secondary low-potential heat sources and obtaining cold in form of cooled water with wide range of low temperatures.
