They have been applied in huilding wall confjgurations to regulate indoor air temperature and humidity so as to further reduce building energy consumption. In this paper , a heat and moisture transfer model that covered the calculation of phase change process was firstly constructed based on coupled heat and moisture transfer theory , which was also known as the coupled heat and moisture phase change enthalpy method. After verification , it was adopted to calculate and analyze application effects of the composite phase change moisture- controlled materials in a comfortable air conditioning room under two circum stances of typical climatic conditions. The associated results indicated that these
