Thermal Effect of Dual-Function Solar Collector on Building in Autumn

Article Preview

Abstract:

In this study, a numerical study is made on a dual-function solar collector integrated with building when it works in thermosyphon water heating mode with natural circulation. The investigation is achieved to show its thermal effect on the building environment by comparing with cooling/heating loads of the rooms with or without the novel collector for the warm autumn periods. The results show that in autumn the thermal effect of the novel system is not inevitable because the cooling load of the room with the collector has an evidently positive difference and the heating load must reduce.
