Heat Transfer Enhancement in Composite Building Wall using Phase Change Material

Abstract Phase Change Materials (PCMs) are capable of reducing the thermal load transfer rate between outdoors and indoors and maintain stability in the indoor temperature when used in building applications. In this study, a variation of layers of two Bio-PCMs integrated with layers of general construction material and insulation have been analyses discretely as well as in combination. The observations from various models have been compared to draw the result and perceive the best model of a Bio-PCM wall for constructing thermally efficient buildings. The wall models have been created and analyzed through Computer Aided Design (CAD) modeling and simulation techniques using Transient Thermal module in ANSYS software. Coconut fat and Palm fat being highly efficient and easily available Bio-PCMs, are used in this study and attractive results have been obtained from them.
