Abstract
Photovoltaik (PV) in Warmfassaden erwärmt sich stark, wodurch ihr Wirkungsgrad sinkt. Phasenwechselmaterialien (PCMs) können dies kompensieren, da sie eine große Menge Wärmeenergie beim Schmelzen absorbieren und dabei die Temperatur wahren. Die Vielzahl an PCMs und Schmelzbereichen und die individuellen Einstrahlungs- und Temperaturverläufe erfordern jedoch eine fallspezifische Auslegung einer PV-PCM-Fassade. Hierfür wird ein Auslegungstool, basierend auf thermischen und elektrischen Berechnungsmodellen, entwickelt. Die Modelle wurden einzeln validiert und eine Ertragsstudie zeigt die Wirkung der PCMs. Eine ganzheitliche Validierung des Tools soll mit Messdaten von PV-PCM-Fassadenteststände in Dresden und Athen ermöglicht werden.
Design of photovoltaic warm facades with phase change materials. Photovoltaics (PV) in warm facades heat up significantly, which reduces their efficiency. Phase change materials (PCMs) can compensate for this, as they absorb a large amount of thermal energy during melting while maintaining the temperature. However, the large number of PCMs and melting ranges and the individual irradiation and temperature curves require a case-specific design of a PV-PCM facade. A design tool based on thermal and electrical calculation models is being developed for this purpose. The models were validated individually and a yield study shows the effect of the PCMs. A holistic validation of the tool shall be enabled with measurement data from PV-PCM facade test rigs in Dresden and Athens.
