An Air Handling Unit (AHU) is an essential component of a modern building’s ventilation and air conditioning system. It’s main purpose is to condition the air throughout a given space, while also regulating its distribution. In short, AHUs effectively create your indoor climate. The key function of an AHU is to draw fresh air into a building, filter it to remove airborne particles, regulate the temperature, and move it around as required. By precisely controlling these processes, the AHU ensures that occupants remain comfortable and healthy at all times. Essentially, then, the AHU provides a necessary balance between keeping the indoors breathable yet safe from outdoor elements.
