How does air handling unit work?

An air handling unit (AHU) is a crucial component of HVAC systems that conditions and circulates air. It works by drawing in outside air, filtering it to remove contaminants, and then either heating or cooling it to the desired temperature. The conditioned air is then distributed throughout the building via ductwork. Additionally, AHUs may include components like humidifiers and fans to maintain optimal indoor air quality and comfort.
