摘　　要：近年来,既有居住建筑中部分散热器用户改造为地板辐射供暖的情况时有发生,且有逐渐增多之势。由于两种供暖末端的水力特性及设计供、回水温度迥然不同,并且地暖系统的循环阻力比散热器增大很多,因此地暖系统与散热器系统并网后会影响整个供暖系统的水力平衡,进而引发热力失调。通过调研北京市地区居住建筑集中供暖用户散热器改造为地板辐射供暖的典型改造方式及实际工程案例,分析不同热用户改造后遇到的问题和对其他用户产生的影响,为后续供暖用户进行地暖改造提供参考。In recent years,the existing residential buildings often have poor heating effect,which leads to some users choosing to change the radiator heating to floor radiant heating and has a gradual increase.Because the water characteristics of the two kinds of heating ends and the design water supply and return temperatures are extremely different,and the circulation resistance of the floor heating system is much higher than that of the radiator,there will be some problems after the floor heating system and the radiator system are connected to the grid.By investigating the typical transformation methods and practical engineering cases of radiator floor radiant heating for central heating users in residential buildings in Beijing,this paper aims to analyze the problems encountered by different thermal users after the transformation and the impact on other users,so as to provide reference for the subsequent floor heating transformation for heating users.
