摘　　要：为推广太阳能空气供暖系统,本文研制开发了3种太阳能空气集热屋面构件,搭建了太阳能空气集热构件热性能测试实验台,对试件进行了不同流量不同进口温度的热性能测试,得到了3种试件在四种流量下的效率方程。分析测试结果发现:3种空气集热构件的最优运行流量均为36~54 m^3/(h·m^2),条缝型孔板渗透型构件性能最优。研究成果为太阳能空气供暖系统设计提供了相关性能参数参考,为下一步太阳能空气供暖系统设计方法的确立提供了帮助。Three solar air collectors which can be integrated on the roof for solar air heating system were developed. The thermal performance of three collectors with different flow rates and inlet temperature was tested.The efficiency equations of three collectors with four flow rates were obtained. According to the test results, the collector with perforated absorbing core has the optimal performance. The recommended flow rate is 36 -54 m3/（h·m2）. It will provide assistance in the design of solar air heating system.
