Thermal performance of phase change paraffin wall in different mass proportions

Phase change material walls are prepared by adding phase change materials into architectural materials in different methods. Phase change material building envelope can save cooling load in the summer because of the thermal storage property of phase change materials. It can decrease energy consumption and the indoor temperature fluctuation, and raise the comfort level. This paper studied the thermal performance of phase change material walls consisting of paraffin and grout in different mass proportions. Energy-saving effect and feasibility of phase change material walls are studied by contrasting with common walls. Results in this paper can provide the basis for the application of phase change material walls to practical buildings.
