摘要： Prevention of the incapability of operation due to crystallization in the absorption solution. When the temperature difference (&Dgr;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 (&Dgr;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 (&Dgr;T) allowing unlimited supply of heat to the high temperature regenerator (1).

摘要： An absorption heat pump and controlling methods thereof for utilizing exhaust heat to obtain high- and low-temperature fluids. The absorption heat pump comprises: a regenerator 1 to which exhaust heat is supplied to evaporate and isolate a refrigerant from a refrigerant liquor; a condenser 2 for condensing refrigerant vapor generated by the regenerator 1; a first evaporator 3 in which refrigerant liquor supplied from the condenser 2 is heated by exhaust heat for evaporation; a first absorber 4 in which the refrigerant vapor evaporated in the first evaporator 3 is absorbed into an absorbent supplied from the regenerator 1; a second evaporator 5 in which refrigerant liquor supplied from the condenser 2 takes heat away from water for evaporation, the water flowing through a heat exchanger pipe 15A; and a second absorber 6 to which part of an absorbent returned from the first absorber 4 to the regenerator 1 is supplied so that the absorbent absorbs the refrigerant vapor evaporated in the second evaporator 5 before being returned to the regenerator 1. The absorption heat pump supplies hot water and chilled water through a hot water pipe 14 and a chilled water pipe 15, respectively. The amount of the cooling water supplied to the second absorber 6, the amount of the refrigerant liquor distributed in the second evaporator 5, and the like are controlled on the basis of the chilled water's temperature detected by a temperature sensor S1.
