介绍了会城门小区节能示范工程的建设背景和示范内容。该工程应用先进的技术与设备，建设了三种不同模式的建筑供暖系统。通过对三类模式系统的测试对比以及大量数据分析，找到了消除水力热力失调、提高热能利用率、节约能源的有效方法，提出了带散热器温控阀的双管系统为未来建筑供暖系统的首选型式，并提出了改造现有单管顺流式系统的具体措施，得出了节能型系统比现有供暖系统节能３０％的结论。
The construction background and demonstration content of the energy-saving demonstration project in Huicheng District were introduced. The project uses advanced technology and equipment to build three different models of building heating systems. Through testing and contrasting the three types of model systems and analyzing a large number of data, an effective method to eliminate hydrothermal imbalance, improve thermal energy utilization, and save energy is found. A dual-tube system with radiator temperature control valve is proposed for the future building heating system. The preferred type, and put forward the concrete measures to reconstruct the existing single-pipe forward-flow system, and concluded that the energy-saving system can save 30% energy compared with the existing heating system.
