Abstract
This study integrates photovoltaic (PV) system, building structure, and heat flow mechanism to propose the notion of ventilated Building-Integrated Photovoltaic (BIPV) walls. The energy-saving potential of the ventilated BIPV walls was investigated via engineering considerations and computational fluid dynamics (CFD) simulations. The results show that the heat removal rate and indoor heat gain of the proposed ventilated BIPV walls were dominantly affected by outdoor wind velocity and airflow channel width. Correlations for predicting the heat removal rate and indoor heat gain, the reduction ratio of the indoor heat gain, CO2 reduction, and induced indoor air exchange are introduced.
Highlights
Building-Integrated Photovoltaics (BIPV) refers to an architectural design approach that combines photovoltaic (PV) panels with the building construction system
This study aims to understand the thermal effect on the innovative BIPV module and to explore the use of thermal management to decrease the thermal impact
The results showed that when the outdoor airflow entered the inlet of the ventilated BIPV wall, part of the airflow would enter indoor through the indoor vent, and part of it would flow upward and out through the top outlet which would be entrained by the outdoor airflow around the outlet
Summary
Building-Integrated Photovoltaics (BIPV) refers to an architectural design approach that combines photovoltaic (PV) panels with the building construction system. This combination allows BIPV to feature a power generation function and to become part of the building façade. Solar irradiation, received by PV cells, would be transformed into heat and cause an increase of the PV. Energies 2011, 4 cell temperature, which is associated with the generation efficiency. Whenever possible, it is necessary to fully enhance a PV’s heat dissipation. Because an irradiated PV panel is a heat source in the BIPV construction, a double-skin design concept can possibly be used to design the BIPV structure as a ventilated BIPV
