According to the characteristics of the construction phase change energy storage material,study this char-acteristics of phase change energy storage material impact on wall body heat.Phase change materials is used to fill the hollow wall.Contrast experiment with ordinary hollow wall was carried out.In order to learn the phase change energy storage material impact on the wall of the heat.The results show that phase change energy storage material is better than ordinary hollow wall in block indoor temperature rise,delayed 1 h.Maintain indoor comfort temperature ability greatly enhanced,make indoor more comfortable.Phase change wall system can effectively reduce the building indoor heat gain,significantly reduce the cooling load of the refrigeration equipment,has important significance for energy sav-ing.
