Abstract

Adding phase change materials to building envelopes can achieve the goals of heat storage and release,improve thermal performance,and energy conservation.This paper introduced the classification and selection of phase change materials,as well as methods for solving phase change heat transfer processes.The correlation between the thermal performance of the envelope structure and phase change material was analyzed.The thermal performance was influenced by regional climate,indoor environment,thermal properties of phase change materials,encapsulation and application methods of phase change materials,etc.Through the application of phase change bricks,phase change concrete,phase change mortar,and phase change wall panels,it was shown that the phase change temperature was close to the arithmetic mean of the ambient temperature,and the increase of encapsulation area,heat transfer coefficient and latent heat of phase change materials could effectively improve their thermal performance and energy efficiency.Studying the thermal performance of phase change envelope structures is of great significance for building energy conservation and carbon reduction.
