基于负荷系数的固定供水温度量调节方程

为了满足计量供热系统热源超量调节和超前调节的要求,避免自主调节用户加热过程的热滞后,引入逐时同类用户及其负荷系数,建立了计量供热系统间连网一次网采用固定供水温度的量调节、二次网采用主动质调节-被动量调节时的运行调节方程.通过实例计算证实了在逐时负荷比值确定后,虽然用户自主调节随机性大,但仍然能够确定供热系统在调节状态下的供、回水温度及其流量,进而预测自主调节状态下的逐时供热量.

The Equation of Flow Adjustment with Fixing Supply Water Temperature Based on Heat Load Ratio

In order to meet the requirement of heat source's oversize adjustment and ahead schedule adjustment with heat metering systems,avoid the heating process's thermo-lag with the consumer independent adjustments,the concepts of homogeneous heat consumers and hourly load ratio were introduced,and the adjustment equations of primary piping network,flow adjustment with supply water temperature fixing and secondary piping network with active quality adjustment and passive flow adjustment in indirect-connected system,were set up.It demonstrates that though the heat consumers' independent adjustments are random greatly but the relative flow rates and temperatures of supply and return water could be calculated out,and the hourly energy requirement for heating in the situation of the heat consumers' independent adjustment were foreseen.
