Commercial and industrial buildings maximise heating, ventilation, and air conditioning (HVAC) systems to effectively maintain indoor air quality and comfort. One component of these systems that must be present on the said properties is the Air Handling Unit (AHU). The AHU relies on a myriad of components, each with a specific role. Hence, regular maintenance must be done to sustain the optimal performance of HVAC systems and ensure they operate seamlessly throughout their lifespan.
The Functions of the AHU
The AHU serves as the lungs of an HVAC system, responsible for circulating and conditioning air within a building. This specific unit is often comprised of various components such as filters, coils, fans, and dampers. All these components play a critical role in regulating temperature, humidity, and air quality. And, to ensure the continuous functionality of the AHU, regular maintenance, including the replacement of worn or damaged parts, must be done by professionals.
Regular AHU Maintenance
The AHU should be subjected to regular maintenance so it can reduce energy consumption and lower utility costs. Regular AHU maintenance can likewise help extend the overall lifespan of the component, improve indoor air quality, reduce downtime and repairs, and assure consistent performance.
Different processes can be done during AHU maintenance. Some of them are as follows.
- Filter Replacement: Filters within the AHU are the first line of defence against airborne particles. Over time, filters accumulate dust and contaminants, impacting airflow and indoor air quality. Regular replacement is crucial to maintain efficient filtration and prevent strain on the system.
- Coil Cleaning: Coils, both evaporator and condenser, are susceptible to dirt and debris buildup. This accumulation hinders heat exchange efficiency, reducing the overall performance of the AHU. Regular coil cleaning and replacement can ensure optimal heat transfer and energy efficiency.
- Fan Inspection and Lubrication: Fans within the AHU play a pivotal role in air circulation. Regular inspection and lubrication of fan components are essential to prevent wear, reduce noise, and maintain the airflow capacity of the system. Any signs of imbalance or damage should prompt immediate attention from professionals.
- Belt and Pulley Checks: Belts and pulleys connect various components within the AHU, facilitating the smooth operation of fans and other moving parts. Wear and misalignment can occur over time, leading to decreased efficiency. Regular checks and timely replacement of belts and pulleys contribute to the reliability of the AHU.
- Damper Adjustment and Replacement: Dampers regulate the flow of air within the AHU, directing it to different zones as needed. Regular inspection ensures that dampers operate smoothly, and any signs of damage or misalignment should prompt replacement. Properly functioning dampers contribute to energy efficiency and temperature control.
- Electronic and Control System Checks: Modern AHUs often feature sophisticated electronic and control systems. Regular checks of sensors, thermostats, and control panels ensure accurate operation and allow for the identification of potential issues before they impact performance.
