Evaluation of the performance of different micro-PCMs in cement brick cavities for passive cooling applications

Abstract

Across the globe, many state governments are insisting on following passive cooling methods for buildings to save energy and reduce emissions. Phase change materials (PCMs) are widely applied in building construction to improve energy performance. The use of micro-encapsulated PCMs is skyrocketing because of their ease of application in solid structures. This paper evaluated the performance of three different micro-PCMs in building wall applications. The performance of a brick with PCM filled holes located at 75 mm from the outer wall, with three different micro-PCMs namely MEP 29, MPCM 28D, and Micronel 28D are evaluated in the work. Various performance and energetic parameters like ATFR, TL, MTR, DF, and MHGR are evaluated in the experiment. For PCM with comparable properties, results with negligible deviations are obtained.
