Cylindrical model of heat transfer in honeycomb structures with microencapsulated phase change material
Original language description
The efficiency of a photovoltaic cell decreases with increased temperature. Excessive overheating caused by the absorption of incident solar radiation reduces the production of electricity. One of the ways to keep the panel cooler is to dissipate the heat from its backside. An aluminium honeycomb structure filled with microencapsulated phase change material (PCM) can dissipate enough heat to reduce overheating and improve the efficiency of the solar cell. Designing of Building's Integrated Photovoltaic systems with PCM requires complex calculations considering wide variety of conditions. Finite element method (FEM) provides a robust tool, but this approach requires a very complex mesh domain due to the thin aluminium wall of the honeycomb structure, as well as iterative calculation process of boundary conditions accounting for complex convective and radiative heat transfer. Both require extensive computation time and FEM are not effective. The paper presents simplified cylindrical heat transfer model, which allows for faster computing with similar results. Comparison of compliance and computation times are included.
