A photovoltaic solar fresh air system, combined power generation by photovoltaic panels with a fresh air system on buildings, was proposed, which generates power by photovoltaic effect while preheating fresh air by photothermal effect. An experimental platform for this system was established. The results of research conducted under winter condition suggests that the average power generation efficiency of this system is 12.7%,the heat-collecting efficiency 24%,and the primary energy efficiency57.3%.The system enables the comprehensive utilization of photoelectric and photothermic energy,improves the power generation efficiency of photovoltaic panels, and heats fresh outdoor air in winter by recycling the heat on the backside of the photovoltaic panels. The system significantly reduces building energy consumption,and enables ventilation to improve indoor air quality and comfort. This system provides a novel method for the application of building-integrated photovoltaic system and building conservation.
