A fresh air handling unit (FAHU) is critical in maintaining indoor air quality (IAQ) and energy efficiency. These units play a vital role in environments such as hospitals, offices, malls, and airports by continuously supplying fresh air and expelling stale air. Regular maintenance is essential to keep your fresh air handling unit working at peak performance. This blog aims to provide information about what an FAHU is, its applications, and critical signs indicating your unit needs maintenance.
Understanding Fresh Air Handling Units
Fresh air handling units like the FlexAir Treated Fresh Air Units provide a complete solution for ventilation, ensuring good IAQ while promoting energy savings. These units incorporate high-efficiency recovery systems like Enthalpy Wheels, critical to their performance. The fresh air handling unit is modular in design, allowing for the addition of heating, cooling, humidification, and high-efficiency filtration modules. It is widely used in air-conditioned spaces such as hospitals, hotels, educational institutes, and pharmaceutical facilities.
The construction of these units is certified by AHRI, ensuring minimal leakage and thermal bridging. The unique design and enthalpy wheels help reduce cross-contamination, making the FAHU an excellent choice for critical environments like healthcare and pharma.
Applications of Fresh Air Handling Units
FlexAir Treated Fresh Air Units serve various sectors by providing a tailored ventilation system. These units, from hospitals to cold storage facilities, ensure fresh air supply while maintaining optimal indoor conditions. They also reduce energy consumption by recovering heat from exhaust air, a benefit made possible by the advanced Enthalpy Wheels used in these systems.
The units are designed for easy customization, allowing users to include additional modules for temperature control, air filtration, and even sound attenuation. By meeting the diverse needs of different facilities, a fresh air handling unit can contribute to better IAQ, energy savings, and regulatory compliance.
Benefits of Fresh Air Handling Units
One of the significant advantages of an FAHU is its ability to pre-condition incoming air. This means the unit delivers fresh air close to the desired indoor conditions throughout the year. Doing so helps meet ventilation standards without significantly increasing energy costs.
Another benefit is the unit’s ability to maintain proper humidity levels, which is especially useful in humid or dry climates. These systems can reduce overall system capacity needs by up to 65%, allowing businesses to lower their energy consumption while maintaining optimal indoor air quality.
Critical Signs That Your Fresh Air Handling Unit Needs Maintenance
Routine maintenance is essential to keep your fresh air handling unit operating at its best. Here are some signs that your system may need servicing:
- Decreased Airflow
If you notice reduced airflow, it could indicate clogged filters or blockages in the system. Cleaning or replacing filters is essential for keeping air moving efficiently.
- Strange Noises
Unusual sounds like rattling or grinding may signal a mechanical issue within the unit. These noises could stem from loose components or worn-out parts requiring immediate attention to prevent further damage.
- Increased Energy Bills
An unexpected rise in energy costs could indicate that your fresh air handling unit is working harder than necessary due to inefficiencies. This may result from dirty filters, clogged ducts, or faulty heat recovery wheels.
- Poor Indoor Air Quality
If occupants in your building begin to complain about unpleasant odors or stuffiness, it may be a sign that the FAHU is not functioning correctly. A system that fails to deliver fresh air can contribute to poor indoor air quality and health issues.
