摘要
对太阳能驱动的Einstein制冷循环进行了详细的热力性能计算,并针对不同的蒸发温度、冷凝温度以及发生温度对系统COP的影响进行了分析计算,得出影响曲线。得出结论:通过改变运行工况来提高系统COP这条路行不通,要从根本上提高系统COP,只能通过对换热器的强化、系统部件的合理布置、以及新工质对的选取等方法来实现。
Detailed thermal performance calculation on Einstein refrigeration cycle system was provided in this paper.The impact of different evaporation temperature,condensation temperature and the occurrence temperature on the system COP was analyzed and calculated,and then the influence curve was revealed.Come to the conclusion:by changing the operating conditions to improve the system COP does not work.Intend to improve the system COP fundamentally,those were done for strengthening of the heat exchanger,reasonable arrangement of system components,and selection of new working medium on methods to achieve.
