新型混合吸收式制冷循环[1] 的特点是能够运用中低温热源 ,热源的可利用温差大 ,制冷系数较高。本文利用效率法对新型混合吸收式制冷循环进行了分析 ,得出新型混合吸收式制冷循环的效率比两效吸收式循环高 ,可达 0 .2 92。同时得出系统各个部件的损失 ,分析吸收式制冷系统在能量的转移过程中的薄弱环节 ,为混合吸收循环系统的优化提供了前提。

The new hybrid absorption refrigeration cycle [1] is characterized by the ability to use low-temperature heat source, heat source available temperature difference, high cooling coefficient. In this paper, the efficiency of the new hybrid absorption refrigeration cycle was analyzed, and concluded that the new hybrid absorption refrigeration cycle  efficiency than the two-effect absorption cycle is high, up to 0.222. At the same time, the  loss of each component of the system is obtained, and the weak points in the process of energy transfer of the absorption refrigeration system are analyzed, which provides the precondition for the optimization of the hybrid absorption circulation system.
