Design of Hydraulic Dynamic Equilibrium in Household Heating System
The operating mode of large flow quantity and small temperature difference is used in the traditional serial heating system, which results in a serious problem of hydraulic misadjustment, leading to visible temperature difference among different rooms. In this paper, in order to realize the hydraulic dynamic equilibrium of heating system and control of household heating, the automatic flow control valves are used for the control of flow rate. On the basis of theory analysis of hydraulic misadjustment, the results show that: the efficiency of heating system and control of household heating can be improved significantly, as well as the energy saving up to 20%.
