PV powered fans

This paper presents a simplified modelling process by using experimental results to form empirical relationships for a particular novel windcatcher natural ventilation and cooling system developed by Monodraught in the United Kingdom. In particular, the behaviour of this system, which is integrated with a DC fan and PV panel without a backup battery, is modelled for the whole year. The impact of natural and night time ventilation with thermal mass on cooling and mitigating overheating is investigated.
