器。1. A high temperature generator of an absorption chiller-heater, comprising: a heating tank, a combustion chamber, and a separator connected to the heating tank via a pumping pipe. Consisting of a high temperature tank and an intermediate temperature tank which are in communication, the intermediate temperature tank has a hollow portion, the hollow portion surrounds the high temperature tank through a flue portion, the high temperature tank, the high temperature tank. A far-infrared radiator is disposed so as to surround it, an inner flue portion is formed between the far-infrared radiator and the high temperature tank, and the inner flue is provided between the far-infrared radiator and the intermediate temperature tank. A high temperature generator of an absorption chiller-heater, characterized in that an outer flue part communicating with the part is formed and at least one of the high temperature tank and the medium temperature tank is provided with a stirring means.
