Definition: A self-contained HVAC system that provides heating, cooling, and ventilation, typically installed on the roof of a building.
Components:
Integrated heating and cooling components (like compressors and gas burners).
Fans for air circulation.
Filters for air purification.
Functionality: Delivers conditioned air directly into the building’s ductwork.
Installation: Primarily installed on rooftops, hence the name, to save space and keep noise away from occupants.
Usage: Common in commercial buildings, retail spaces, and warehouses where centralized climate control is needed.
Definition: A component of an HVAC system that is used to regulate and circulate air as part of a heating, cooling, and ventilation system.
Components:
Fans to circulate air.
Coils for heating or cooling (can be connected to chillers or boilers).
Filters for air quality.
Dampers for airflow control.
Functionality: Typically does not include a compressor; relies on other systems (like chillers) for cooling and heating.
Installation: Usually located indoors or in mechanical rooms, often connected to duct systems throughout the building.
Usage: Used in larger HVAC systems where more specialized temperature and humidity control are needed.
Key Differences
Design: RTUs are self-contained units; AHUs require additional systems for heating and cooling.
Location: RTUs are mounted on rooftops; AHUs are usually found indoors.
Functionality: RTUs handle both heating and cooling on their own, while AHUs typically require external systems for temperature regulation.
