| Abstract |
This paper focuses on applications to a thermal collecting(hereafter referred to as suncatcher) system for the increase of solar radiant energy intensity in the north surface of building. This suncatcher system uses the same principle as concentrating solar collectors and ?Le four solaire d'Odello?of French. This paper performs its fundamental study through the simplified numerical model. Preliminary results indicate the suncatcher system could provide profitable conditions for solar thermal collection of the north surface in all climates. As a passive device, application of suncatcher baffle outside the north surface in building could significantly increase the level of thermal collection on a sunny day. Consequently, the suncatcher system is proved to be an effective device for the improvement of environment performance in the north surface. An additional study is required to establish the complete suncatcher system on the basis of this research. This approach could have implications for energy efficiency and conservation, effectively utilizing the free resource of solar radiation. |
