Research on Determination of Optimum Constant Pressure Point of Heating System
Through the placement of different circulating water pump positions in the heating pipe network and the combination of the position of the fixed pressure point,the water pressure diagram was drawn and an-alyzed to determine the changing law of the influence of the circulating water pump and the setting of the fixed pressure point on the system pressure;the circulating water pump was obtained.The position of the heating system determines the position of the pressure limit point of the heating system,and the position of the constant pressure point determines the size of the limit pressure value of the system.Finally,the exact position of the optimal constant pressure point of the system is determined by deriving the energy conservation equation on this basis.
