What Are AHU Controls?
AHU controls refer to the systems and components that manage the operation of an Air Handling Unit. These controls regulate key parameters such as airflow, temperature, humidity, and pressure to ensure that the HVAC system meets the specific requirements of a building.
Key Components of AHU Controls
- Programmable Logic Controllers (PLCs): The brain of the AHU, managing all operations.
- Example: Carel pCO Large PLC
- Sensors: Measure environmental conditions such as temperature, humidity, and CO2 levels.
- Actuators: Operate dampers and valves to regulate airflow and temperature.
- Example: Belimo Rotary Actuator LR24A-MP
- Variable Frequency Drives (VFDs): Adjust fan speeds for energy efficiency.
- Example: ABB ACH580 Variable Frequency Drive
- Building Management Systems (BMS): Integrate AHU controls into a centralised platform for real-time monitoring and control.
The Benefits of AHU Controls
1. Energy Efficiency
AHU controls optimise the operation of fans, motors, and other components, reducing energy consumption and lowering utility costs.
2. Improved Indoor Air Quality
By monitoring and adjusting airflow, humidity, and filtration, AHU controls ensure that indoor air remains fresh, clean, and comfortable.
3. Enhanced System Reliability
Proper controls prevent overloading and wear on components, extending the lifespan of the AHU and reducing maintenance costs.
4. Compliance with Standards
AHU controls ensure compliance with regulations such as HTM (for healthcare) and ISO 16890 for air filtration.
5. Flexible Zoning
Advanced controls enable zoning, allowing different areas of a building to maintain unique temperature and airflow requirements.
