Description

With modern heating and cooling systems, consumers are paying more and more attention to comfort, energy saving and consumption reduction.

To achieve these two points, it is necessary to meet the requirements of each end flow of the system within the design flow range. One problem is to ensure that when the flow at each end of the heating and cooling system fluctuates within a certain pressure difference range, or when the system is under partial load operation, the flow at each end is always within the design flow range, thereby effectively ensuring user comfort. At the same time, waste of energy is avoided.
