Abstract:
This paper reports the study results of the comparative performance testing between a single glass window (SG) and two Models of Multi-Purpose Glazed Solar Chimney combined with Hot Water Collector Systems (GSC-HWC). To make unbiased comparison, they were all installed into the south façade of a small house model with the same dimensions. The component parts of the GSC-HWC structure are the external and internal clear-glass-panel walls. A space gap between the walls has been used to control the indoor air and installed with a black-painted pipe for making hot water.
The experimental results revealed that indoor temperature of two models of the GSC-HWC rooms was less than that of single glass window (SG) rooms. The GSC-HWC could induce ventilation and reduce thermal radiation from sunlight although the daylight gain appears to be nearly the same among SG room and the two GSC-HWC rooms. In addition, the internal structure of the two GSC-HWC models has a system for making high-temperature water. Consequently, the GSC-HWC models are on-premise promotional solar energy use, save energy in cooling and heating, and protect our environment to stop global climate change.
