Influence of novel PCM-based strategies on building cooling performance

Abstract

Phase change materials (PCMs) with considerable energy storage density show promise for building cooling performance enhancements, but the cooling performance is highly dependent on novel PCM-integrated forms and intelligent control strategies. This chapter provides a state-of-the-art review of novel PCM-based strategies for building cooling performance enhancements. The strategies investigated include PCM-integrated forms (such as distributed and coupled systems) and combined strategies (such as high-reflective coatings, radiative cooling walls, and hybrid ventilation). Heat transfer mechanisms for both distributed and coupled systems have been characterized to provide an in-depth understanding. Solutions for system performance enhancement of novel PCM-based cooling systems have been comprehensively presented. Future studies and prospects have been demonstrated as avenues for future research. This study presents a systematic overview of novel PCM-based strategies for cooling performance enhancement, together with technical challenges of the widespread applications. Research results are critical for the application and promotion of novel PCM-based cooling strategies in buildings.
