HEAT AND COOLING SUPPLY METHOD USING ABSORPTION THERMO-TRANSFORMER Russian patent published in 2023 - IPC F25B15/00 F22B33/18 

FIELD: energy; housing; communal services; thermal power plants running on gas fuel.

SUBSTANCE: energy, housing and communal services and thermal power plants running on gas fuel. Absorption lithium bromide thermo-transformer (ALBT) with single-stage absorption is used in the heat pump mode for operation in the heat supply mode, and in the refrigerating machine mode for operation in the cold supply mode. Deep utilization of low-grade heat of combustion products is carried out in the flue gas and condensate circuit by removing flue gases from the ALBT gas hot water boiler and generator and pumping them through the ALBT evaporator with simultaneous condensation of water vapor contained in the flue gases in the lower part of the outlet chamber of the ALBT evaporator. The heat of the cooling water is removed in the cooling water circuit by pumping the cooling water from the cooling tower through the cooling water supply valve from the cooling tower, the ALBT absorber, the ALBT generator and then through the cooling water supply valve to the cooling tower back to the cooling tower.

EFFECT: saving fuel during the heating season, reducing emissions of harmful substances.
