For the air-conditioning system, what is the function of the AHU?

The function of the Air Handling Unit (AHU) primarily focuses on central ventilation. An AHU is designed to regulate and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. It draws in outside air, filters it, conditions it (by heating or cooling), and then delivers it throughout the building via ducts. This central ventilation capability is crucial for maintaining indoor air quality, controlling temperature, and ensuring that fresh air is supplied to occupants.

While controlling humidity, facilitating heat exchange, and managing condensate drainage are important functions in an overall HVAC system, they can be considered secondary roles related to the broader responsibilities of air conditioning and heating systems. The AHU's primary purpose is to provide a means of ventilating and circulating conditioned air, making it integral to central ventilation processes in building utilities.
