Abstract
The present building energy consumption can be reduced by replacing the air conditioning system with Thermal Energy Storage (TES) system. In this present work, a semianalytical model is applied to analyze the shell and tube type TES system for air cooling-heating application. The laminar forced convection heat transfer phenomena in between phase change material (PCM) inside a shell and air inside the tube are studied. The heptadecane PCM with 22°C melting temperature is used for this TES system. The melting front propagation is also analyzed. The outlet air temperatures are found 24°C to 26°C for the 32°C inlet air temperature.
