摘　　要：将间接连接供热系统的一、二次网视为一个整体,提出在部分负荷时二次网采用控制流量比大于60%,一次网采用控制流量比大于30%的同时,改变循环流量和供回水温度的质-量调节方法。通过建立指数函数关系的流量调节规律方程,并加以优化分析,得出了一、二次网的流量调节公式、供回水温度调节公式以及相应的变化曲线。Through taking the primary and secondary networks of indirectly connected heating system as a whole, a new temperature-flow regulation method is proposed. In this method the flow ratio of primary network is more than 60% and that of secondary network is more than 30%,and both circulating flow and the temperatures of supply water and return water are changed when there is only partial load. After establishing and optimizing the flow regulation law with exponent function form,the equations for flow regulation and supply water and return water temperature regulation and their corresponding curves in primary and secondary network＇ are put forward.
