ABSTRACT
The determination of thermophysical properties of the PCM is a very important step in the process of thermal management by assessment of energy saving performance of PCM composites and for evaluation of the energy-saving performance. In this paper, measured and theoretical values of thermophysical properties of a composition of 50% of PCM mixed with gypsum were used to perform numerical simulations by two methods for five thicknesses of panels (10, 30, 50, 70 and 90 mm). The first method is a numerical simulation of heat transfer by conduction in the panels by using experimental values of thermophysical proprieties and the second method is a numerical simulation of heat transfer by conduction in the panels by using theoretical values of thermophysical proprieties. The results of these numerical simulations revealed that the maximum difference in the temperature swing between the two methods can reach 1.1°C.
