Abstract
Abstract Deployment of phase change materials in buildings for thermal management had enthralled researchers for the past two decades owing to high energy storage per unit volume and isothermal action during phase change. This paper presents an experimental investigation of phase change materials being integrated in layers within concrete block for thermal management. Two identical concrete building blocks are constructed and their thermal performance was evaluated with and without integration of PCM under natural environment. Thermal analysis results reveal that PCM integrated concrete block exhibited less temperature fluctuations than block without PCM. Results reveal that maximum air temperature was reduced up to 3 °C was observed in the concrete block with PCM, compared to block without PCM. Also, addition of PCM results in flattened temperature profile within concrete block. Further, the effect of varying PCM thickness was also evaluated and results reveal that thickness of 12 mm was optimum for the employed concrete block space and above which no significant change was found.
