摘　　要：通过工程实践,总结出室内热水供暖系统垂直单管异程式改造为同程式的经济实用方案;在分析同程式管网传统水力平衡方法后得出,只需计算两根相邻立管间的供、回水干管压降,使供水干管与回水干管压降差值和压差累计值不超过主立管压降的10%,即可实现水力平衡,且达到设计要求;应用中进一步简化为计算图表,有助于提高设计效率。Based on the project practice,the thesis system form direct return to revert return,which is economic provided a transformation scheme of hot water heating and reasonable. After analysing the traditional method of the hydraulic calculation of the reverse return system draws a conclusion that aims at the hydraulic balance, nothing but calculating pressure drop of the main riser＇s pipes between one uprightness pipe and the next need to be calculated. If the scale of the total pressure drop is less than 10% scale of the main riser＇s pipe pressure drop,the system can be in the state of hydraulic balance and design requirement may be researched. Compiled the diagrams for calculating in application can raise the efficiency in the design.
