平板太阳能空气集热器热性能的实验研究

An Experimental Research on the Thermal Property of Flat Plate Solar Air Collector

设计了一种太阳能空气集热器,对其热性能进行了实验研究。通过实验,分析了冬季3个典型日的集热效率和空气流量、进出口温度、太阳辐射强度间的关系。结果表明,出口温度随太阳辐射强度的增加而增加,集热效率随着空气流量的增大而增大。同时给出了太阳能空气集热器的效率方程。

A solar air collector is designed and experimental researches are made on its thermal performance.Through the experiment,the paper analyzes the relationship between collection efficiency and air mass flow,import and export temperature,and the intensity of solar radiation in three typical days in winter.The results show that with the increase of the intensity of solar radiation,outlet temperature increases,with the increase of air mass flow,collection efficiency is big.Also,the efficiency equation of the solar air collector is given.
