PURPOSE:To increase a heat recoverying rate and improve a coefficient of performance by a method wherein an absorption heat recoverying heat exchanging part and an absorbing heat radiation part are arranged within a container of an absorbing device, weak solution is dispersed from the upper part of the container and refrigerant vapor is fed from the lower part of the container. CONSTITUTION:An absorbing heat recoverying heat exchanging part 52 and an absorbing heat radiation part 53 are arranged within a longitudinal container 50 of an absorbing device 36 in such a way that they are directed from the upper part to the lower part, wherein weak solution 58 and refrigerant vapor 44 are contacted while being oppositely flowed so as to exchange their substances from each other. With such an arrangement as above, vapor 44 and solution 58 become composition near a balanced state at each height of the absorbing container 50 and its composition is continuously varied in response to its height. Accordingly, since a balanced state between the vapor 44 and the solution 58 is continuously held while the refrigerant vapor 44 ascends, there occurs a less amount of variation in temperature of the solution as the state is transferred to a new balanced state as found in the case that the weak solution is contacted with the refrigerant vapor not balanced at the upper part of the absorbing device. As a result, it is possible to increase an amount of heat recovery and to improve a coefficient of performance. |
