【摘要】 采用有限时间热力学法对两级制冷压缩系统进行了热经济性分析,得出了两级制冷压缩系统内可逆循环热经济性的目标方程,以及目标方程取最小值情况下系统的性能参数、设计参数.同时研究了系统两循环的工作温度、系统的工作年数与热经济性目标方程的关系.更多还原

【Abstract】 A finite-time thermoeconomic performance analysis was carried out for a two-stage endorever-(sible) combined refrigeration cycle model.The thermoeconomic objective function for this system was derived.The optimal performance parameters and design parameters for minimized objective function were obtained.The relation between the temperatures of working fluid,working years and the thermoeconomic objective function was investigated.更多还原
