摘　　要：通过对单管跨越式供暖系统在定压差、定流量条件下的模拟计算,分析了两种情况下用户行为调节产生的系统水力失调度,讨论了两种控制方法的优缺点。结合变频泵的应用,提出了适合单管跨越式供暖系统的控制方式。The thesis analyses the degree of hydraulic misad justment caused by users' adjustment through simulation calculation under the condition of the steady pressure difference or the steady flow in the single pipe cross-over heating system, and discusses the merit and the demerit of two control schemes. Combining the application of variable speed pump, the rational control scheme for this heating system is given. 
