PURPOSE: A two-stage driven hot water absorption chiller is provided to increase the use efficiency of hot water by separating refrigerant from absorbed liquid two times. CONSTITUTION: A two-stage driven hot water absorption chiller comprises a first shell(100) and a second shell(200). The first shell is composed of an eliminator(130), an evaporator(110) and an absorber(120). The evaporator distributes the refrigerant supplied from a condenser through a refrigerant line and cools the cold water from a cold water line. The absorber is installed on the right side of the eliminator, cools the refrigerant evaporated by the evaporator and the thick liquid which has been supplied and distributed from a low temperature regenerator through a thick liquid line with the cooling water of the cooling water line and makes thin liquid by mixing the refrigerant and the thick liquid. The second shell is composed of a high temperature regenerator(210), a low temperature regenerator(220), a condenser(230), and an eliminator(240). The high temperature regenerator heats the thin liquid with the heat of the hot water supplied through a hot water line(410) to evaporate the refrigerant to form intermediate liquid. The low temperature regenerator heats the intermediate liquid with the heat of the hot water of the hot water line to evaporate the refrigerant to form thick liquid. The condenser condenses and liquefies the refrigerant evaporated by the high and low temperature regenerators with the cooling water of the cooling water line. The hot water of the hot water line is provided to the low temperature regenerator via the high temperature regenerator and from the low temperature regenerator, the intermediate liquid is distributed to the hot water line.
