Abstract

Use of PCMs is very difficult in liquid state because it has instability form. To solve to this basic problem, we should achieve a stability of state and shape. However, this simulation indicate thermal performance is less because in this experiment, the small amount of PCM was applied and it contributes to have less thermal performance. Therefore, we suggest macro-packed PCM to increase content in this study. The phase transitions for n-octadecane, n-eicosane, and n-docosane, occurred in 29.76 ˚C, 35.75 ˚C and 43.16 ˚C respectively, and also their heat latent is 256.5 J/g, 189.0 J/g, and 241.3 J/g. consequently, the results of experiment show: macro-packed PCMs have highest thermal performance rather than pure PCMs. Finally, due to thermal performance evaluation, the macro-packed PCMs that contain n-octadecane have useful application for final material in buildings.
