新型变色幕墙太阳能空气集热器冬季热性能实验研究

Experimental study on thermal performance of a new type solar air collector with colored facade in winter

介绍了一种新型变色幕墙太阳能空气集热器(简称SCCF),这种装置具有冬季供暖和夏季降温的双重功能,在冬季夜间还可起护板的作用,以减少窗户的热损失。实验研究了安装在普通住宅的SCCF装置在不同工况下的集热性能和供暖效果,实测结果表明:SCCF进出风口空气平均温差可达38℃,集热面积为5m^2的SCCF可使实验房内空气平均温度比对比房高3～5℃,SCCF夜间可提高窗户外表面平均温度2.1℃,起到良好的保温作用。

Presents an advanced solar air collector with colored facade （SCCF） which has double effects of heating and cooling and can also be used as an insulated plate during night in cold winter to reduce heat loss from windows. Experimentally studies the thermal performance and heating effect of this device installed in a residence under several different conditions. The results show that the air temperature difference of SCCF at the air inlet/outlet can reach to 38 ℃, average indoor temperature of the tested room with SCCF （5 m^2 ） is about 3 to 5 ℃ higher than the reference room, and the average external surface temperature of window with SCCF at night is 2. 1℃ higher than that without SCCF.
