摘要(Abstract)：

太阳能建筑供暖技术的研发在太阳能资源丰富的西藏自治区(下文简称为“西藏”)等地区具有潜在的实际应用价值。研发设计了一种太阳能空气集热器，并制造了该太阳能空气集热器样机；然后在拉萨市自然太阳光条件下(测试当日的太阳辐照度在161.8～1588.0 W/m~2之间，均值为1316.3 W/m~2)，太阳能空气集热器采用跟踪太阳模式时对其集热性能进行了测试。测试结果表明：该太阳能空气集热器的进风口空气温度(即环境温度)均值为22.45℃，经过太阳能空气集热器被太阳辐射加热后，可产出温度在51～85℃之间、风量为150 m~3/h的热空气，出风口空气温度均值达到68℃，最高值接近拉萨市水的沸点(86℃)，表明该设备的集热效率高。研发设计的太阳能空气集热器在集热性能上具备实际应用价值。
