.Air Handling Units (AHUs) and Fan Coil Units (FCUs) are both HVAC equipment, but they serve different purposes and have distinct differences:
*AHU (Air Handling Unit)*
1. *Centralized system*: AHUs are typically part of a centralized HVAC system.
2. *Air treatment*: AHUs treat the air by heating, cooling, humidifying, dehumidifying, and filtering.
3. *Air distribution*: AHUs distribute the treated air to various zones or areas through a network of ducts.
4. *Large capacity*: AHUs have a larger capacity to handle more airflow and serve larger spaces.
5. *More complex*: AHUs are more complex systems that require more maintenance and technical expertise.
*FCU (Fan Coil Unit)*
1. *Decentralized system*: FCUs are typically part of a decentralized HVAC system.
2. *Air cooling/heating*: FCUs cool or heat the air using a coil and fan.
3. *Local air distribution*: FCUs distribute the cooled or heated air locally, typically through a short duct or directly into the space.
4. *Smaller capacity*: FCUs have a smaller capacity to handle less airflow and serve smaller spaces.
5. *Less complex*: FCUs are less complex systems that require less maintenance and technical expertise.
Key differences:-
*System type*: AHUs are part of centralized systems, while FCUs are part of decentralized systems.-
*Air treatment*: AHUs provide more comprehensive air treatment, including humidification, dehumidification, and filtration, whereas FCUs primarily cool or heat the air.-
*Air distribution*: AHUs distribute air through a network of ducts, while FCUs distribute air locally through a short duct or directly into the space.-
*Capacity*: AHUs have a larger capacity than FCUs.-
*Complexity*: AHUs are more complex systems that require more maintenance and technical expertise than FCUs.
