【摘要】 性能良好的太阳能集热器是太阳能空调的关键设备之一。广东省江门市太阳能空调系统采用了一种高效的平板集热器 ,其主要技术特征是增加了一块聚碳酸脂 (PC)透明隔热板。本研究通过对比试验 ,确定了一种高效平板太阳能集热器的技术方案 ,并测定了瞬时效率曲线 ,其热损系数仅为 2 90W/ (m2 ·℃ )。更多还原

【Abstract】 Good performance of the solar collectors is one of the important elements for solar air conditioning system.A novel type of high efficient flat plate solar collector was applied to the solar air condition system in Jiangmen,Guangdong Province.Tests show that adding a transparent polycarbonate sheet in gap between glazing and absorber of the collector. The coefficient of the thermal loss is reduced to 2.90W/(m 2℃) and the performance of the collector is improved.更多还原
