Numerical Analysis of Performance of a Building Integrated Photovoltaic-thermal Collector System

摘要：

A computational fluid dynamics (CFD) model of a novel building integrated photovoltaic thermal collector is studied to determine the effect of active heat recovery on cell efficiency and to determine the effectiveness of the device as a solar hot water heater.Parametric analysis indicates that cell efficiency can be raised up to 4% and that water temperatures of 55℃ are possible under the conditions investigated.A new correlation is developed relating collector inlet temperature,ambient temperature and insolation that allows cell efficiency to be calculated directly.
