太阳能热风发电系统的空气集热器试验装置的研制

根据太阳能热风发电系统集热器的抽象试验研究模型,研制了该系统的空气集热器试验装置,设计了该装置的集热器箱体、太阳能辐射模拟装置、流量和温度测量系统、辐射强度测量系统以及数据采集系统.利用研究装置进行了变太阳辐射强度、变空气流量以及环境温度对空气集热器的热量影响实验,初步试验验证装置的可行性.

Experimental device setup for solar chimney collector

The experimental device for solar chimney collector was set up by the way of simplification of the practical solar chimney collector.The experimental device includes the collector trunk,the simulant of solar radiation,the measuring systems of air flow rate and temperature and the data acquisition system.All parts were introduced briefly and some experiments have been done.Temperature differences between the inlet and outlet of the collector and collector efficiency under the conditions of variable solar radiation,air flow rate and ambinent temperature were obtained.The preliminary experiments verify the feasibility of the setup.
