Application of phase change material (PCM) in the glazing structure can improve its thermal performance by enhancing its thermal
energy storage capacity. In this study, the effect of thermophysical parameters of PCM on thermal performance of a PCM-filled doubleglazing
unit was investigated. The results show that the temperature time lag of the PCM-filled double-glazing unit increases and the
temperature decrement factor decreases with the increase of density, thermal conductivity, specific heat capacity, latent heat, and melting
temperature of PCM. Increasing density, latent heat, and melting temperature of PCM are effective to enhance the thermal performance
of PCM-filled double-glazed units; however, enhancing thermal conductivity and specific heat capacity are ineffective when thermal conductivity
is beyond 2.1 W/(m K) and specific heat capacity is < 4460 J/(kg K).
