PURPOSE: To obtain constant output irrespective of exhausted heat volume by a method wherein diluted solution of a generator is heated by burner heating and also heated by exhausted heat heating of an exhausted heat recovery heat exchanger.
CONSTITUTION: Diluted solution flowing into a generator 1 through a diluted solution pipe 11 is heated by exhausted heat through an exhausted heat collecting heat exchanger 14 and releases refrigerant steam. The concentrated solution passes an orifice 16 mounted on a lower part of a solution pan 15 and flows out into a lower part of the generator 1. The solution in the lower part of the generator 1 is heated by flame of a burner 4 through a wall of a flute 2 and a heat transmission pipe 3 and releases refrigerant steam. The refrigerant steam generated by exhausted heat heating through the exhausted heat collecting heat exchanger 14 and the refrigerant steam generated by the burner heating at the lower of the generator 1 join in a refrigerant steam space 5 and flow toward a condensor through a refrigerant steam pipe 13. On the other hand, the solution concentrated by the burner heating to have a necessary concentration becomes a concentrated solution, which flows out of a concentrated solution pipe 12 toward an absorber.
