Energy-saving analysis on heating system with distributed variable frequency pump

In this paper, the heating system with distributed variable frequency pump is analyzed. As the theory of dynamic distributed heating system improves gradually, which controlled by climate compensator, and for its great capacity of energy-saving, more and more heating systems become to use it, especially in the improvement works. In the paper, the author analyses how to design the system and the factors which influence the energy saving, and provides some suggestions for the users. It is shown that the factors of the position of pressure difference point and system back-pressure are influential in the heating system with distributed variable frequency pump energy saving.
