摘　　要：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/m2之间,均值为1316.3 W/m2),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 m3/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。The research and development of solar energy building heating technology has potential practical application value in regions such as Tibet Autonomous Region,where solar energy resources are abundant.In this paper,a solar air collector has been developed and designed,and a prototype of the solar air collector has been manufactured.Then,under natural sunlight conditions in Lhasa(the solar irradiance on the test day is between 161.8 and 1588.0 W/m2,with an average value of 1316.3 W/m2),the solar air collector is tested for its heat collection performance using the tracking sun mode.The test results show that the average air temperature at the air inlet(equivalent to ambient temperature)of the solar air collector is 22.45℃.After being heated by solar radiation from the solar air collector,hot air with a temperature of 51~85℃and an air volume of 150 m3/h can be produced.The average air temperature at the air outlet reaches 68℃,and the highest value is close to the boiling point of water in Lhasa(86℃),indicating that the heat collection efficiency of the equipment is high.The solar air collector studied and designed has practical application value in terms of heat collection performance.
