吸收循环冷水大温差系统理论效率分析

Theoretical efficiency analysis of absorption cycle refrigeration system with large temperature difference of chilled water

为实现吸收循环冷水大温差制冷系统节能运行 ,提出简单吸收循环、双蒸发器循环及双蒸发器双吸收器循环 3个方案 ,分别建立了各方案的联合卡诺循环模型 ,并根据可逆过程热力学原理 ,完成了理论COP的推导 ,定量分析和比较了各方案。

In order to make the absorption cycle refrigeration system economical operation under large temperature difference of chilled water conditions, gives three absorption refrigeration cycle schemes, i.e. simple absorption cycle, two evaporators cycle and two evaporators and two absorbers cycle. Respectively establishes combined Carnot cycle model for each scheme. Based on reversible thermodynamic principle, deduces COP of ideal cycle. Quantitatively analyses and compares each mode.
