Abstract
Due to the raise in global warming and green house effects, the concept of energy efficiency is increasingly investigated in recent times. Among the different methods of achieving energy efficiency, passive cooling techniques can be suitable option for achieving intensive interior temperature maintenance. In this work, a novel form stable phase change material (FSPCM) was developed using expanded perlite. The developed FSPCM was implemented for a real time building model to understand the efficiency in reducing the internal temperature. In total, four scaled building models were developed with different roof setups such as (i) conventional RC roof installed with clay tiles, (ii) conventional RC roof installed with cool-roof tiles, (iii) Roof installed with macro-encapsulated PCM tile, (iv) roof installed with FSPCM tile. All the scaled prototypes were installed with temperature sensors for monitoring the reduction in internal temperature and to compare the efficiency of the different models. All the temperature data measured were recorded using an Arduino based data acquisition (DAQ) system. In addition to the experimental studies, a detailed 2-D finite element analysis (FEA) was performed using the commercial ANSYS software with the aim of performing a detailed parametric study.
