SIMPLIFIED NUMERICAL MODELLING AND SIMULATION OF A PHOTOVOLTAIC HEAT RECOVERY SYSTEM

摘要

A residential-scale building integrated photovoltaic (BiPV) cogeneration system has been numerically modelled and validated with experimental data. The investigation identifies an elegant synthesis between heat recovery and PV cell cooling. A rectangular ducting unit has been designed and constructed to act as both a cooling duct and a heat recovery unit. The convection of the air behind the panels will serve to cool the PV panels while providing a heat source for the residence. This paper will describe the heat transfer model created in the Engineering Equation Solver software package (EES). It is created from standard heat transfer equations, which form a series of highly coupled non-linear partial differential equations. The resultant simulations and their correlation to experimental data are presented. The heat transfer model is being created in order to act as an algorithm for a decision support tool for building professionals. This is one of two companion papers to be delivered on the heat transfer and fluid flow modelling of a modular PV/Thermal system.
