The combined use of static balancing valves and dynamic differential pressure balancing valves offers significant advantages in addressing hydraulic imbalance in HVAC systems:

Static Balancing Valve: By adjusting the gap between the valve core and the valve seat, the static balancing valve alters flow resistance to balance the flow distribution among system branches. This ensures that each branch receives the designed flow during the initial hydraulic adjustment, effectively resolving static hydraulic imbalance.

Dynamic Differential Pressure Balancing Valve: This valve automatically adjusts its opening based on pressure differential, maintaining a constant differential pressure in the system. It effectively responds to changes in operating conditions and mitigates flow fluctuations, ensuring stable system performance.

By combining both valve types, the system can comprehensively address both static and dynamic hydraulic imbalance, enhancing overall hydraulic balance, reducing energy consumption, and improving operational efficiency. Additionally, it helps minimize equipment failures and maintenance costs caused by hydraulic imbalance.

The advantages of proportional-integral (PI) control valves in energy saving and consumption reduction are mainly reflected in the following aspects:

Precise Control: PI control valves can monitor and precisely regulate parameters such as fluid flow and pressure in real time, effectively avoiding energy waste and overconsumption. By applying proportional and integral mathematical principles, they achieve fine-tuned adjustments for high-precision control.

Optimized Regulation: The valve's regulation characteristics allow it to automatically adjust the valve opening according to system demands, ensuring optimal operating conditions and reducing energy consumption.

Stability and Reliability: PI control valves offer excellent stability and reliability, enabling long-term, steady operation and minimizing energy waste caused by equipment failures.

High Degree of Automation: These valves support automated control, reducing the need for manual intervention, improving operational efficiency, and thereby indirectly lowering energy costs.

In summary, with advantages such as precise control, optimized regulation, high stability, and automation, PI control valves effectively contribute to achieving energy-saving and consumption-reduction goals.
