The Analysis of Efficiency and Safety of the Plan of Quantity Adjustment in Heating System
To direct at heating system when it adopts quantity adjustment. Taking a community in Zhangjiakou as an example, using the method of Graphic theory to analysis and compare these two operation schemes: adjusting parallel pump's valve in shared pipeline and adjusting parallel pump's valve in non-shared pipeline. We can know that adjusting parallel pump's valve in non-shared pipeline is energy-saving, when the flow in pipe network is bigger than 79% of the boiler's total circulating water. There is a lowest limit of system's circulating water, when adopt the method that adjusting the parallel pump's valve in non-shared pipeline, otherwise it would damage the pump.
