Abstract :
The heating system with distributed variable frequency pump is a heat-supply system in which the flow rate is regulated with return-water pressured pumps, instead of valves, set at return water pipe on the high-temperature side of heat exchange in substation. As the heating system has no valves to consume energy, much energy is saved. In this paper, the factors that the position of pressure difference point and system back-pressure are influential in the heating system with distributed variable frequency pump energy saving are analyzed.
