Performance Evaluation of a Dual-Function Solar Collector Integrated with Building in Water Heating Mode

Abstract:

The study is for the water heating mode of a novel building integrated solar thermal system named as building-integrated dual-function solar collector. The novel system avoids summer overheating in hot climate and water-freezing in cold climate, meanwhile remains low operating cost as passive solar heating system. For the novel system at the water heating mode, experiment study was carried out in a hotbox, and dynamic numerical model has been established. The experimental and numerical results show that the characteristic thermal efficiency of the collector achieves 47.386% in water heating mode.
