以热力学第二定律为基础 ,通过对TFE/NMP(一种对环境友好的新型工质对 )吸收式制冷机热力过程的火用分析 ,指出了能量转化过程中的薄弱环节 ,并研究了各种工况对系统的COP和ECOP的影响以及如何控制某些参数使系统COP和ECOP达到最佳 .通过增加冷媒过冷器 ,可以明显地提高系统COP和ECOP值 .分析其结果为该系统的性能提高以及优化设计提供理论依据
Based on the second law of thermodynamics, the exergy analysis of thermodynamic process of TFE / NMP (an environmentally friendly new working pair) absorption chiller is used to point out the weak links in the process of energy conversion. The influence of operating conditions on the system COP and ECOP and how to control certain parameters can optimize the system COP and ECOP. By adding the refrigerant subcooler, the system COP and ECOP values can be significantly improved. Improve performance and optimize the design to provide a theoretical basis
