Abstract
Prevention of the incapability of operation due to crystallization in the absorption solution. When the temperature difference (.DELTA.T) between the temperature of the concentrated absorption solution Tr detected by the temperature sensor (22) and the temperature of crystallization Tc for the concentrated absorption solution at a specified concentration detected by the concentration sensor (21) comes within a prescribed figure, the opening of the heat control valve (20) is decreased by a specified figure, 20% for example. When the concentration of the concentrated absorption solution, which is measured by the concentration sensor (21), exceeds a prescribed figure, 65% for example, the heat supplied to the high temperature regenerator (1) is reduced by decreasing the opening of the heat control valve (20) regardless of the above temperature difference (.DELTA.T). When the concentration of the concentrated absorption solution comes below a prescribed figure, 59% for example, the opening control for the heat control valve (20) is not conducted regardless of the above temperature difference (.DELTA.T) allowing unlimited supply of heat to the high temperature regenerator (1).
