The Effect of Shielding Barriers on Solar Air Collector Gains

Abstract

The paper deals with numerical simulations of the impact of location and orientation of the solar air collector located on the roof of a building and on its thermal performance. The solar collector is used to preheat an air, which then is supplied into the building. The solar collector is placed on the roof, which is shielded from barriers. To achieve the desired objective, numerical simulation of the annual operations of the collector in the software BSim was performed. Real climate data for Central Europe were used. The result of this work is to determine the effect of shielding barriers on the usable annual heat gain, which is represented by preheating of external air.The paper deals with numerical simulations of the impact of location and orientation of the solar air collector located on the roof of a building and on its thermal performance.
