The definition of an AHU HVACHVAC system is a system that is designed to provide heating, ventilation, and air conditioning (HVAC) to a building or space. An AHU HVACHVAC system is typically composed of several components, including a heat exchanger, a blower, a filter, and a controller. The heat exchanger is responsible for transferring heat from the air outside the building to the air inside the building. The blower is responsible for circulating the air throughout the building, while the filter removes dust and other contaminants from the air. Finally, the controller is responsible for regulating the temperature of the air in the building. All of these components work together to ensure that the building is kept at a comfortable temperature and that the air quality is maintained. An AHU HVACHVAC system is a great way to ensure that a building is kept comfortable and safe for its occupants.
