在混凝土砌块中填入相变石膏板，构成复合相变混凝土砌块，将其运用到建筑外墙中。在实验室搭建变温热箱实验装置，通过实验与模拟验证焓法模型在计算相变传热时的可行性，并运用焓法模型计算分析由复合相变混凝土砌块砌成的建筑外墙的热工特性。研究表明，用焓法模型计算得到的模拟值与实验值的误差不超过5%。通过焓法模型计算分析得到，当室内空调定温为26℃时，相变石膏板相变温度为26℃节能效果最佳，将这种相变石膏板放置在混凝土砌块外侧孔中，相变外墙房间节能59.1%，节约电费61.4%；放置在砌块内侧孔中，相变外墙房间节能45.3%，节约电费48.2%。

Composite phase change concrete blocks applied in building exterior walls are formed by putting phase change plasterboard in concrete block. The enthalpy method is used to simulate and calculate, the variable temperature hot box is used to validate the accuracy of the enthalpy method, and the thermal performance of the exterior wall built with composite phase change concrete blocks is calculated using the enthalpy method. The results show that it’s concluded that the relative error of calculating phase change heat transfer by the enthalpy method is no more than 5%. When the indoor air conditioning temperature is 26 ℃ constantly and the phase change temperature of phase change plasterboard is 26 ℃, the energy-saving effect is the best. When putting this kind of phase change plasterboard in the outside layer of concrete block, 59.1%of energy and 61.4% of power are saved;when putting it in the inside layer of concrete block, 45.3% of en-ergy and 48.2%of power are saved.
