AHU Control Panel

An AHU Control Panel is used to monitor and regulate the operation of an Air Handling Unit (AHU) in HVAC systems. It ensures proper airflow, temperature, humidity, and air quality in buildings such as commercial spaces, hospitals, and industrial facilities.

Key Components of an AHU Control Panel:

1.Programmable Logic Controller (PLC) or DDC (Direct Digital Controller) – Automates control based on programmed logic.

2.Variable Frequency Drives (VFDs) – Control the speed of blower fans for energy efficiency.

3.Temperature & Humidity Sensors – Monitor environmental conditions for proper air regulation.

4.Differential Pressure Sensors – Ensure proper filter and airflow monitoring.

5.Dampers & Actuators – Regulate fresh air intake and exhaust.

6.Heaters & Cooling Coils Control – Manage heating and cooling elements (electric/gas heaters, chilled water coils).

7.Air Quality Sensors (CO₂, VOCs, etc.

8.Fire & Smoke Detection Systems – Shut down AHU in case of fire to prevent smoke circulation

9.Human-Machine Interface (HMI) or Display Panel – Provides real-time monitoring and control

10.Communication Interfaces (BACnet, Modbus, LonWorks, etc) – Enable integration with Building Management Systems (BMS)

Functions of an AHU Control Panel:

• Automatic Temperature & Humidity Control – Adjusts based on setpoints.
• Fan Speed Regulation – VFDs optimize energy use.
• Fresh Air & Recirculation Control – Ensures proper ventilation.
• Filter Monitoring & Alarms – Alerts when filters need replacement.
• Fault Detection & Diagnostics – Displays errors and warnings.
• Integration with BMS – Remote monitoring and control
