摘要:
在考虑了集热器的热损失,斯特林热机的热阻、热漏和回热损失的基础上,建立了不可逆太阳能斯特林热机模型。讨论了温度比、吸热温度等参数对整个系统无量纲功率和总?效率的影响,通过线性加权评价函数方法对系统的无量纲功率和总?效率进行多目标优化。研究得出:线性加权评价法求得的最佳温比的数值范围为x2opt<x<x1opt其可使功率与总?效率达到最佳折中;通过使太阳能斯特林热机达到最佳吸热温度TH,增大聚光比C和回热器效率εR,减小集热器的对换系数h和导热桥损系数k0,可提高太阳能斯特林热机的无量纲功率与总?效率。
Abstract:
This paper establishes an irreversible solar Stirling heat engine model. The effects of heat loss of the collector, thermal resistance of the Stirling heat engine, heat leak and recovery, temperature ratio,endothermic temperature,and concentration ratio on the dimensionless power and total exergy efficiency of the whole system were analyzed. A multi-objective optimization problem considering the system’s dimensionless power and total enthalpy efficiency was formulated and resolved based on the linear weighted evaluation function method. The results show that the optimal temperature ratio obtained by our method is greater than x2opt and less than x1opt,which can achieve the best compromise between dimensionless power and total exergy efficiency.The dimensionless power and total exergy efficiency of the solar Stirling heat engine can be improved based on the optimal endothermic temperature TH,by increasing the concentration ratio C and regenerator efficiency εR,and reducing the heat transfer coefficient h and thermal bridge loss coefficient of the collector k0.
