Abstract::This paper studies a phase change material for building envelope in hot summer and warm winter area, which is the mixture of methyl palmitate and methyl stearate with a certain ratio. Phase change temperature and latent heat of phase change material was detected by DSC. When the mass ratio of methyl stearate and methyl stearate was 4 to 1, the phase transformation temperature of the material was 22.4oC, and the latent heat was 188.7 J/g, which presents the best performance and the phase transition temperature meets the requirements of the building envelope in hot summer and warm winter area. This phase change wall material is prepared by composing of phase change material and building material, which can control indoor temperature and reduce energy consumption of air conditioner. It may have good application prospect in the field of building energy conservation.
