摘要
抛物面槽式太阳能聚光集热器是太阳能中高温热利用过程中的关键组件。基于槽式太阳能集热系统实验平台,依据运行测试条件,针对稳态测定方法的不足,对动态测试方法进行实验研究。通过实验数据分析有效集热量及热损失的变化规律,研究其热损失机理,拟合集热器总面积的有效集热量及热损失实验关联式,以表征高原槽式太阳能集热器在不同辐照度运行工况下的有效集热量及热损失。研究结果为高原槽式太阳能集热器在实际工程中应用奠定了实验基础。
Parabolic trough solar concentrator is a key component in the process of solar energy utilization at high temperature. According to the operation test conditions, and aiming at the shortage of steady state measurement method, the dynamic testing method was studied based on the experimental platform of the solar energy trough collector system in Lhasa . Through the experimental data, the heat loss and the change of the effective heat collector were analyzed, the heat loss mechanism was investigated, and the effective heat collector and heat loss correlation were fitted to characterize the effective heat collector and heat loss of the total area under the different irradiance. The research results lay an experimental foundation for the application of Tibet trough solar collector in practical engineering.
