The objective of the present work is to model the thermal energy storage unit using Nano Enhance Organic Phase Change Materials (NEOPCM). NEOPCM is capable of absorbing or releasing the large quantity of latent heat during phase change. This paper investigatesNEOPCM with Lauric acid as a base material and nanoparticles (Copper Oxide, Aluminum Oxide)as supporting materials for the preparation of NEOPCM. In this paper, it was studied experimentally the effect of combinations of nanoparticles CuO and Al2O3 with different mass fractions to the base PCM, Lauric acid. To ensure the uniform dispersion a field emission scanning electron microscope (FESEM) has been used. In order to determine the changes in the compositional/functional groups during the cycle test, Fourier Transform Infrared (FT-IR) spectroscope is used. Crystalloid phase of NEOPCMs is investigated with an x-ray test conducted by an x-ray diffractometer (XRD). Thermal reliability is carried out by accelerated thermal cycle tester, phase change temperature and latent heat of fusion are measure by Differential Scanning Calorimeter (DSC).Thermal conductivity of NEOPCM is measure by using a KD-2 pro, which is based on hot wire technique.It was also verified experimentally that there is improvement in thermal conductivity and storage capacity of NEOPCM.
