Choosing the Right Synchronization Method

Time-based Synchronization

Time-based synchronization involves programming the AHU units to operate in a pre-determined sequence at specific times. This method ensures that only the required number of units operates during different occupancy periods within a building. Time-based synchronization is relatively straightforward to implement but may not account for dynamically changing conditions and instantaneous requirements.

Demand-based Synchronization

Demand-based synchronization utilizes sensors and feedback mechanisms to adjust the operation of AHU units based on real-time occupancy, temperature, humidity, and air quality data. This method allows for more adaptive and responsive synchronization, optimizing energy consumption based on actual demand. However, demand-based synchronization requires intelligent control systems capable of analyzing and acting upon the collected data effectively.

Combination Synchronization

Combination synchronization involves a hybrid approach, combining elements of both time and demand-based synchronization methods. This approach allows for flexibility in managing different scenarios and ensures a balance between energy efficiency and occupant comfort. Combination synchronization provides the advantages of both methods, offering a comprehensive solution for AHU system optimization.
