Abstract
Abstract Conservation of energy and reduction of carbon dioxide footprint are among the most crucial global challenges faced by humanity. Dozens of solutions have been so far introduced to address this issue. Nano‐phase change materials (nano‐PCMs) are new emerging technology that are vastly being studied which are believed to minimize energy waste. This study focuses on many aspects of nano‐PCMs with applications in the building industry. It was found that carbon‐based nanoparticles have the greatest thermal properties to be integrated into the PCMs. In this work, a summary of the previous review articles regarding PCM and nano‐PCM following the comparison of various types of nano‐particles in terms of their impact on thermal conductivity enhancement of PCMs is reported. Moreover, other influencial thermophyical properties of nanoparticles such as size, concentration, dispersion, shape, and inclination angle and their effect on thermal properties of PCMs are discussed.
