をさらに向上させることができる。Since the present invention is configured as described above, it has the following effects. (1) Similar to the conventional double-effect cycle, when the diluted solution flowing out of the absorber is heated by the refrigerant vapor generated in the high temperature regenerator to become a concentrated liquid, the refrigerant vapor is released to become refrigerant water. At the same time as recovering the latent heat that is generated, the exhaust gas from the high temperature regenerator is introduced into a circuit in parallel with a separately provided low temperature regenerator for exhaust heat recovery and used to concentrate the diluted solution that also flows out from the absorber. Since the exhaust heat of exhaust gas is recovered by this method, the heat of combustion exhaust gas can be efficiently recovered, and the temperature of the combustion exhaust gas released to the atmosphere is lowered, so white smoke can be prevented and the atmospheric temperature rises. Can be prevented, the coefficient of performance of the refrigeration cycle can be improved, and the fuel consumed in the high temperature regenerator can be saved. (2) When the absorber and the condenser are air-cooled, the coefficient of performance can be further improved.
