| dc.title | Thermal performance of modelling of naturally ventilated photovoltaic facade in buildings in Hong Kong | en_US |
| dcterms.abstract | Photovoltaic technology has been applied in buildings worldwide for energy conservation and sustainability. Compared with the traditional double skin facade, the outer glass glazing is replaced by photovoltaic (PV) panel and openings were set at top and bottom of the PV panel in the naturally ventilated double skin PV facade. The cooling effect is achieved by removing the heat in the cavity created by the buoyancy introduced air flow. The numerical simulation with Computational Fluid Dynamics (CFD) method has been conducted to study the thermal performance of a naturally ventilated double-skin facade integrated with amorphous silicon (a-Si) solar cells in Hong Kong. This research shows a high consistency both with numerical simulation and the practical testing methods. Furthermore, the 2D CFD mode was tested to be valid. After the overall evaluation under different weather conditions, 70 to 90cm is considered to be the optimum air gap depth range when less heat transfers into the room. The weather condition of high ambient temperature and unclear sky has been concluded as the initial obstruction in applying naturally ventilated PV facade. Widening the air outlet performed better than other structure optimization methods in removing heat. Due to the size of the hot box which is only 1.2m height, the air flow in the cavity may be easily affected by the operating condition. Therefore, full size model is recommended for future research. | en_US |
