Abstract
Microencapsulated phase change material (PCM) is used for industrial and house hold air conditioning system for longer term usage. In this study 1-Tetradecanol (C14H30O) is used as a core material. Urea (CH4N2O)-Formaldehyde (CH2O) is used as shell material. Micro capsulation is made using in-situ polymerization technique. Prepared microcapsules were tested for feasibility to use cooling system. The average size was verified using Scanning Electron microscope (SEM) and result was found 3µm and shape was observed as spherical and surface morphology was smooth. The presence of chemicals of core and shell materials was verified by Fourier Transform Infra-Red spectroscopy (FT-IR). The peak temperature of microcapsules was found as 150°C from Thermo Gravimetric Analyzer (TGA). Thermal cyclic stability was verified by Differential Scanning Calorimetry (DSC). The cyclic temperature was observed as 45.9°C and 39.78°C. These prepared microcapsules can used to control the temperature of 37°C. This prepared microcapsule can be used for room air conditioning system
