i-Cool Integration of Phase Change Materials into Metropolitan Car Concepts to Control the Cabin Temperature

This paper presents the modeling results of an innovative i-cool system for controlling the cabin temperature of a standalone car facing the solar energy from the sun. Project work indentifies the best possible phase change material (PCM) to be used for i-cool system is n-Heneicosane which shows maximum total heat flux is 44189 W/m². From all the PCMs n-Heneicosane, n-Eicosane and n-Nonadecane that were shortlisted in selection criteria shows 600 sec to achieve inner surface temperature equal to the outer surface for a metropolitan car. While without use of PCM, the metropolitan car takes 320 sec & total maximum heat flux is 32900 W/m². The final selection of n-Heneicosane shows 34.25% efficiency over conventional car.
