摘要
为了研究平板式太阳能空气集热器的集热效率,对不同形状吸热板的集热效率进行了动态测试.结果表明,使用穿孔吸热板的平板太阳能空气集热器的出风口温度和集热效率均明显高于使用无孔波纹吸热板的太阳能空气集热器.该集热器可增加对太阳辐射热能的吸收,加强吸热体和空气的对流换热.
A dynamic test of the heat-collecting efficiency of different types of collectors was carried out to study the heat-collecting efficiency of fiat solar air heaters. The results showed that the temperature at the air outlet and the heat collecting efficiency of the solar air heater with a perforated absorber flat plate were apparently higher than those of the solar air heater with a non-porous corrugated absorber plate. Therefore, the former solar air heater was proved to be able to absorb more radiant heat energy from the sun to increase the heat convection between the absorber flat plate and the air.
