| 摘 要： | 研究了不同设计供回水温差和质调节对下供下回异程式系统允许最大不平衡率的影响。设计供回水温差降低，系统允许最大不平衡率Jmax增大，说明减小设计供回水温差有利于系统的平衡。在系统满足设计要求的前提下，质调节时供热系统更趋于稳定。

| Abstract: | The influence of different design temperature difference between supply water and return water as well as constant flow control on maximum permissible unbalance rate of downfeed and direct return riser system is studied. The maximum permissible unbalance rate J_(max) of the system increases when the design temperature difference between supply water and return water reduces. That shows that reducing design temperature difference between supply water and return water is favourable to the system balance. On the premise of design requirements satisfied by the system, heating system further tends towards stability during constant flow control. |
