Abstract：
Based on the building thermal zone and building heating demand,this paper analyses the decreasing rule of the building room temperature during heating accidents,and gives the limited heating coefficients of typical cities and the recommended value of the additional coefficient of the heating heat exchanger.The research can provide references for the design and selection of the heat exchanger.
