Abstract
Refrigerant vapor generated in a high temperature regenerator is condensed in a condenser, and the refrigerant vapor is changed to refrigerant liquid. Then it is conducted to a first evaporator. The refrigerant vapor evaporated in the first evaporator is absorbed in a solution in a first absorber. The refrigerant liquid conducted from the condenser without vaporizing in the first evaporator is introduced to a second evaporator, and it evaporates in the second evaporator. The refrigerant vapor in the second evaporator is absorbed in the solution in a second absorber. The first and the second evaporator and the first and the second absorber are made of a unitary chamber. The first evaporator is juxtaposed to the second absorber with a heat transfer member. The concentration of the refrigerant in the second evaporator is controlled by a refrigerant liquid controller that controls a flow rate of the refrigerant liquid flowing from the first evaporator at the predetermined value.
