Fuel gas triple co-generation marine polar region museum life support system

The utility model discloses a gas triple co-generation marine polar region museum life support system. The system comprises a gas generator set, a flue gas type lithium bromide refrigerating unit andan absorption heat exchanger, the smoke type lithium bromide refrigerating unit comprises a high-pressure generator. The high-pressure generator is provided with a heat exchange flue gas channel; a fuel gas exhaust flue of a fuel gas internal combustion engine of the fuel gas generator set is connected with a heat exchange flue gas channel of the high-pressure generator. The internal combustion engine cylinder sleeve cooling water channel is connected with heat source input of a plate heat exchanger; heat exchange output of the plate heat exchanger serves as a driving heat source of the absorption heat exchanger to be connected with a heat source generator of the absorption heat exchanger. An evaporator in the absorption heat exchanger is connected with a cooling pipe loop of a flue gas lithium bromide unit conden
