摘　　要：以建筑集成的太阳能空气集热建筑模块为研究对象,利用与实际住宅等大的实验平台,针对不同的集热板形式和空气流动方式对集热建筑模块热性能的影响进行了实验研究。重点讨论了开孔平板型、开孔孔径大小以及设置空气间层分隔板等对改善集热建筑模块热性能的影响。实验结果表明,开孔平板型较实心平板型的热性能得到明显的改善,孔径优化后(孔径为5mm、孔间距为15mm)的热效率可提高30%以上;另外,设置空气间层分隔板相对于小孔径(d=5mm)而言,采用大孔径(d=10mm)时出风口升温效果更明显。Experimental study of the thermal performance of building-integrated solar air collector was executed based on different forms of collect plates and air flow pattern within collector by using the test cells as like actual housing.Focused on effect of pore size of the perforated solar air collector and the baffle board set in inter air gap of solar air collector on improvement of thermal performance.Experimental results show that thermal performance of perforated solar air collector is more significantly improved than the solid plate-type, the optimized aperture （diameter 5mm, hole spacing 15mm） can increase the thermal efficiency of 30% or more than others; In addition, set the baffle board in inter air gap of solar air collector, relative to the small diameter （ d = 5mm）, outlet temperature rise of the large aperture （d = 10mm） is more obvious.
