Evaluation on the performances of a ventilated and non-ventilated cavity behind a BIPV: Modelling and experimental monitoring
MetadataShow full item record
Integrating electronic parts and batteries for stand-alone solutions in unitized curtain wall system is an innovative concept. This brings new challenges and problems that are investigated by this research. Since these electronic components may be conveniently located inside the cavity behind the PV module, the risk of overheating should be minimized, and this can be achieved by ventilating the cavity. This study aims at investigating how the air temperature in the cavity varies in the two building integrated photovoltaics (BIPV) configurations that were tested (with and without natural retro-ventilation). A model is developed and validated against experimental data, to provide design feedback and maximize the energy performance of photovoltaic modules integrated into the façades. Results show that even a small air flow can significantly reduce the temperature inside the cavity, especially in winter conditions, minimizing the risk for the entire active system`s performance, and positively affecting temperatures in the neighbouring indoor environment.
