In building projects, HVAC systems often include components called Air Handling Units (AHUs) and Fan Coil Units (FCUs). Both play important roles in controlling indoor air quality and temperature but operate differently. An AHU typically handles large volumes of air, conditioning and distributing it throughout a building via ductwork. In contrast, an FCU is usually smaller and serves specific zones or rooms by circulating air locally.
AHUs are generally part of centralized HVAC systems and can include filters, heating and cooling coils, and fans. FCUs, on the other hand, are more compact and often found in individual rooms or smaller areas, providing heating or cooling directly to that space without extensive ductwork.
**Why this matters**
Understanding the distinction between AHUs and FCUs helps in making informed decisions during building design and maintenance. It ensures the right equipment is selected for efficient climate control, energy use, and occupant comfort. Clear knowledge of these units also facilitates better communication among project teams and stakeholders.
