HYBRID COGENERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To supply cold/hot water to a building stably in an air-conditioning load region of an absorption cold/hot water machine while effectively using the sensible heat of exhaust gas from a generation unit and residual oxygen therein for greatly improving the heat efficiency.

SOLUTION: The hybrid cogeneration system 1 comprises the generation unit 2 for generating power with the burning of fuel, a reheat burner 31 using the residual oxygen in the exhaust gas from the generation unit 2 as burning air for burning the fuel, and the absorption cold/hot water machine 3 having the reheat burner 31 as well as a regenerator for separating refrigerant from absorbed liquid and an evaporator for evaporating the refrigerant and serving for generating cold water or hot water to be circulated and supplied to a building. Exhaust gas from the reheat burner 31 of the absorption cold/hot water machine 3 is supplied to the regenerator and power generated by the generation unit 2 is used for driving the generation unit 2 and the absorption cold/hot water machine 3 to distribute the amount of fuel to be supplied to the generation unit 2 and the reheat burner 31 in accordance with at least one of the air-conditioning load of the absorption cold/hot water machine 3 and power requirement for the generation unit 2.
