介绍了两种新型太阳能通风窗的原理和结构,以已有的控温热箱为基础,建立了太阳能通风窗实验平台,在亚热带气候条件下,对普通单层窗、自然通风双层窗、强迫通风双层窗进行了对比实验研究。结果显示,相对于普通单层窗,在基本满足室内采光要求的前提下,自然通风双层窗可以减少室内得热的 38%; 强迫通风双层窗可以减少室内得热的 62%, 明显降低了空调系统的冷负荷和能源消耗。

Two novel ventilated solar screen windows were introduced and an experimental rig has been set up based on a temperature-controlled building hot box in Hong Kong, a subtropical city. The contrastive experimental study of single glazing window, nature ventilated double glazing window and force ventilated double glazing window has been done. Experimental results showed that the nature ventilated double glazing and force ventilated double glazing window can reduce the indoor heat gain through the window 38% and 63% of single glazing window, respectively. Under the condition of fulfilling indoor lighting standard by using of daylight, the energy consumed by air-conditioner is reduced evidently.
