The Analysis of Adjustment Modes of District Heating System
Abstract:
In order to reduce the power consumption of circulating pump in secondary network., the adjustment that combines quantity adjustment and quality adjustment is proposed in the paper;and the control strategy and adjustment equations in different stages of this adjustment mode are present. Then taken a community in Zhangjiakou as an example, the adjustment curve of this mode in indirectconnected heating systems and direct-connected heating systems are obtained. Finally the power consumptions of the adjustment mode proposed in the paper with that of quality adjustment and quality adjustment with different quantitative ratio in each period are compared; the result indicates that the adjustment mode has more potential in energ-saving.
