摘　　要：以太阳能通风墙为研究对象,利用已建成的1∶1实体模型,针对不同构造的集热板、集热罩和热传输方式对太阳能通风墙热性能的影响进行了试验研究。试验结果表明,集热墙与地下蓄热式通风口同时开启的工况下,白天室内平均温度提高了7.6℃,夜间提高了1.8℃,且温度下降速率缓慢,有效地抑制了室温的波动;单框双玻塑钢集热罩腔体内温度白天的峰值为62.3℃,在20:00室外温度为6.1℃的情况下仍能达到16.5℃左右,比Ⅰ型高1.8℃,阻止了腔体热量损失的减少,提高了建筑的热稳定性;蓝膜集热板白天的集热效率比普通集热板高3%左右,夜间的保温性能更是比其高出了一倍。An experimental study of the effect of the thermal performance was made of the solar-induced ventilation wall based on different structures of heat-collecting plates, heat-collecting covers and heat transmission. The solarinduced ventilation wall is regarded as the research object according to the 1：1 entity model built. The results suggest that the room temperature increased by 7.6℃ during the day, the temperature increased by 1.8℃ at night and the dropping rate of temperature was slow. It is effective to control the fluctuations of indoor temperature when both the heat-collecting wall and the vent of underground heat storage are open. The highest temperature of the heat-collecting covers with the single box and double glasses was 62.3 ℃. It could still be around 16.5 ℃ when the outdoor temperature was 6.1 ℃, 1.8 ℃ higher than the heat-collecting covers with the single box and glasses. It can prevent the loss of cavity heat and improve the stability of the building. Heat-collecting efficiency of blue file panels is around 3% higher than the ordinary during the day and the thermal insulation property is twice higher than common one at night.
