Performance Analysis of Evaporative Absorption Exchanger-Absorption Refrigeration Cycle
In order to optimize the performance of absorption refrigeration cycle,a thermodynamic analysis is carried out on an evaporative absorption heat exchange-absorption refrigeration cycle.The high pressure condenser temperature T8 and the tempera-ture difference ∆TEAX in the outlet of evaporative absorption heat exchanger were chosen as independent variables.The correspond-ing relationship between ∆TEAX and medium pressure throttling temperature T12 is studied,and the influence of T8 on the value range of ∆TEAX is analyzed.The change of solution degassing range in the cycle was investigated,and the influence of ∆TEAX on re-frigerant flow,cycle cooling capacity QE and η was analyzed.When the outlet temperature of the high temperature generator and ∆TEAX are constant,there is an optimal T8 to maximize the cycle η.With the increase of ∆TEAX,the optimal T8 increases gradually,and the corresponding η maximum decreases gradually.
