When it comes to designing an HVAC system that checks all the boxes—efficiency, comfort, and reliability—selecting the right air handling unit (AHU) is a critical decision. Whether you're working on a commercial office, a hospital, or a food processing facility, the AHU must be tailored to the space's specific needs.
In this guide, we’ll walk through the key selection factors, explore customization options, dive into industry-specific demands, and introduce you to trusted AHU manufacturers represented by VHF Sales.
Key Factors in Selecting an AHU
1. Capacity & Airflow Requirements
An AHU must be properly sized to handle both the airflow and the thermal load of the space. Under sizing can compromise comfort, while oversizing wastes energy. Consider:
CFM (cubic feet per minute) requirements
Static pressure needs
Zoning and ventilation strategies
2. Energy Efficiency & Sustainability
Energy-efficient AHUs are a must for reducing operational costs and meeting green building goals. Look for units featuring:
ECM (electronically commutated motors)
Heat recovery systems (enthalpy wheels, plate exchangers)
VFDs (variable frequency drives) for dynamic control
3. Customization & Modular Design
No two buildings are exactly alike. Modular and custom AHUs offer:
Flexible dimensions and configurations
Specialized filtration (HEPA, UVGI for infection control)
Built-in humidification (SteamOvap systems are a great option)
Corrosion-resistant wall panels or coatings for industrial or coastal sites
4. Indoor Air Quality (IAQ)
Especially critical in healthcare, education, and lab settings, premium IAQ features include:
HEPA filtration for fine particulate removal
UV-C lighting to inhibit microbial growth
Integrated humidity control to support occupant health
Different Industries, Different Demands
Different sectors have unique environmental and performance requirements. Here’s how AHU needs vary by application:
Healthcare Facilities: Require tight humidity control, HEPA filtration, low-leakage, and redundancy for infection prevention and patient safety.
Commercial Buildings: Focused on energy savings, occupant comfort, and flexible zoning for changing tenant needs.
Industrial Settings: Often need robust construction, corrosion-resistant materials, and high static pressure for large, low-leakage ductwork systems.
Hospitality & Spas: Prioritize quiet operation, humidity control, and energy-efficient performance to maintain guest comfort.
Educational Institutions: Demand enhanced IAQ and low noise levels to support learning environments.
Laboratories & Cleanrooms: Require ultra-clean environments with strict air quality control and specialized pressurization.
