摘　　要：本文针对由线聚焦菲涅尔反射器太阳能集热器组成的发电和制冷系统中的蓄热罐,采用数学建模和实验测试方法,对线聚焦菲涅尔反射器集热系统的蓄热罐蓄热、放热性能进行了分析,蓄热罐采用工业应用较为成熟的三元熔融盐为储热介质,利用材料相变蓄存热量。利用ANASYS软件对蓄热罐的传热过程进行了模拟,依据仿真结果分析传热过程和机理,并通过实验测试对数值模型进行了验证。The endothermic and exothermic heat transfer performance of thermal storage tank in the solar power and cooling system driven by linear Fresnel reflector（LFR） solar collector was analyzed numerically and experimentally. For this thermal storage tank, the industrial intermediate-temperature molten salt was chosen to be the energy storage material and the energy storage was mainly based on the capacity of the material＇s phase change process. The ANSYS software was utilized to simulate the heat transfer process of thermal storage tank. The process and mechanism of the heat transfer were analyzed according to the simulation results and the numerical model was validated through the experimental test.
