Comparison Analysis of Lower Temperature PCM on Phase Change Energy Storage Process at Different Models

Abstract:

This article simulation studies the thermal Characteristics of a lower temperature phase change materials (PCMs) using in the building energy storage by two different models. In the process of phase change, liquid phase is used as two ways of heat exchange: pure heat conduction and natural convection, and we exploit CFD software to carry out numerical simulation. To compare and analyze under melt and solidification, the proportion of solid and liquid, the time of phase change, the interface of phase change and motion temperature image of liquid-region.
