摘　　要：研究了下供下回异程式分户计量供暖立管系统最不利环路间允许的最大不平衡率,建立了压力不平衡率、水力失调度与室内温度波动三者之间的数学关系,得到了在标准供热工况(95/70℃)下,系统最不利环路间允许的最大不平衡率,给出了计算结果与分析。The maximum allowable unbalance rate for the downfeed and direct return riser system of individual metered heating system in the most unfavorable circuit is studied. The mathematical relationship among the pressure unbalance rate, hydraulic disorder rate and indoor temperature fluctuation is established. The maximum unbalance rate of the system in the most unfavorable circuit is obtained under the regime of standard heat-supply (95/70 ℃). The calculation result and analysis are given.
