| 摘 要： | 本文以《民用建筑供暖通风与空气调节设计规范》（GB50736-2012）为基础，对室内热水供暖系统中热媒供回水温度降低为75％／50％这一技术问题进行了分析，研究了水力计算中比摩阻的计算方法。利用管径、流量与比摩阻的关系式，编制了热水供暖系统供回水温度在75％／50℃时的管径计算表，这对于按照新规范设计室内热水供暖系统具有一定的参考价值。

| Abstract: | This article analyzed the problem of heat medium temperature reducing to 50℃/75℃ in the indoor hot water heating system on the basis of the HVAC new rules, introduced the calculation method of specific frictional resistance in hydraulic calculation. Through the relation of the pipe diameter, flow and of specific frictional resistance, the pipe diameter calculation table at 50℃/75℃ of hot water heating system is figured out. It has a certain reference value for the design of indoor hot water heating system in the future. |
