Description

technical field [0001] The invention relates to a method for adjusting the hydraulic dynamic balance of a water supply network on the primary side of a heat exchange station system. Background technique [0002] The functional structure of modern buildings is complex, and the demand for heating is diverse and time-varying. The demand for heat in each loop of the heat exchange station-network water system is different and changes dynamically. Therefore, even if the water flow of each loop meets the design requirements , the heat transfer effect of each loop is still unbalanced. Moreover, due to changes in the demand of some loops, the water flow of the system will inevitably increase or decrease, and the hydraulic balance of the system will also change accordingly, resulting in a new hydraulic imbalance. For the constant-flow water system with throttling orifice plate, manual regulating valve and other components installed in each loop, the resistance and flow distribution o...

AI Technical Summary

Problems solved by technology

In actual use, throttling components such as throttling orifice plates, regulating valves, and dynamic flow balance valves are often damaged, which will affect actual adjustment and use, and the maintenance cost is high

Moreover, in the actual use of the above method, there will be hydraulic imbalance and uneven distribution of water flow, which will cause insufficient heat supply in some heat exchange stations and excess heat supply in some heat exchange stations. At the same time, it will also cause a lot of energy waste and increase economic cost

The water supply network system on the primary side of the existing heat exchange station is often divided into several blocks according to the characteristics of the end load, and each block forms a water system loop, resulting in different loads of the heat exchange station, resulting in uneven resistance in each loop of the entire water system balance problem
