Abstract

This invention relates to an absorption type heat exchanging apparatus having an evaporation unit, an absorption unit, a condensation unit and a regeneration unit. A diluted absorption liquid transfer pipe and a concentrated absorption liquid transfer pipe are installed between the absorption and regeneration units. A pump placed in one of these pipes is connected to a power take-off device which is placed in the other pipe and which is adapted to have rotative driving power imparted thereto by the absorption liquid in the pipe. Rotative driving power is imparted to the power take-off device by the energy based on the difference between the pressures in the regeneration and absorption units. This rotative driving power is transmitted to the pump. Thereby, the power to be provided to the pump from the outside is reduced.
