In HVAC language, what does "AHU" stand for?

In HVAC terminology, "AHU" stands for Air Handling Unit. This is a vital component in heating, ventilating, and air conditioning systems. The primary purpose of an air handling unit is to regulate and circulate air as part of a central heating and cooling system. An AHU usually contains fans, heating and cooling elements, filters, and dampers to manage indoor air quality and comfort levels.

The effectiveness of an AHU is critical for distributing conditioned air throughout a building, as well as for managing humidity and maintaining appropriate temperature levels. Unlike the other options, which misinterpret the core function of the unit, the term "Air Handling Unit" correctly encompasses its role in both heating and cooling processes, making it fundamental to achieving a comfortable indoor environment.
