太阳能热风发电系统集热器性能的影响因素分析

Study on the performance influential factors of collector in the solar chimney power system

太阳能集热器是太阳能热风发电系统的重要组成部分。进入集热器的空气流量、辐射强度、环境温度、集热器内的蓄热体和集热棚的高度等参数,对集热器性能都有一定的影响。通过试验对影响集热器性能的诸因素进行了研究,并分析了各因素对太阳能热风发电系统空气集热器性能的影响。

The air collector is one of the most important parts in the solar chimney power plant system. Main factors that influence the performance of air collector are the solar radiation, the ambient temperature, the collector height, the volume flow of the air entering the collector, and the storage material in the collector. Experimental research has been done to reveal the influence laws of these factors on the performance of the air collector.
