Computer Fluid Dynamics Assessment of an Active Ventilated Façade Integrating Distributed MPPT and Battery

Abstract

Ventilated Faç ades integrated with photovoltaic panels have become a popular way to improve both the thermal-physical performances of the existing built environment. The increased usage of not-programmable renewable energy sources implies the adoption of energy storage systems to mitigate the mismatch between the power generation and the building's demand. Aiming at properly integrates a photovoltaic panel and a battery (Lithium based) as a module of an active ventilated faç ade, the prototype design has been carried out in terms of thermo-fluid dynamics performance. Based on experimental setup, a numerical study of flow through the air cavity of the active ventilated faç ade has been carried out by the fluid-dynamics Finite Volume code-Ansys-Fluent. The calibrated model was lastly used to perform a wide range of parametric analyses on different climate and boundary conditions to explore the viability of the prototype.

Experimental and Computational Fluid Dynamic Study of an Active Ventilated Façade Integrating Battery and Distributed MPPT

“…In this context, the paper presents the thermo-fluid dynamics performance of a prototype of an active ventilated faç ade integrating PV module and a lithium battery starting from a previous preliminary authors' work [24]. CFD steady state simulations have been performed to investigate the effects of the buoyancy-induced by the thermal gradients within the air cavity of ventilated faç ade.…”
