A multizone air handling unit (AHU) is a type of HVAC system that is designed to serve multiple zones or areas within a building or other enclosed space. Multizone AHUs are typically used in systems where the heating and cooling needs of different areas within a building are significantly different, or where it is not practical to install separate AHUs for each area.

In a multizone AHU, the air is drawn into the AHU and passed through a filter to remove contaminants and impurities. The air is then conditioned using a heating, ventilation, and air conditioning (HVAC) system, which regulates the temperature and humidity of the air. The conditioned air is then distributed to the various zones or areas being served by the AHU through a network of air ducts.

Multizone AHUs typically have a number of features and components to help condition and distribute the air, including filters to remove contaminants and impurities, heating and cooling elements to regulate temperature, and humidity control systems to regulate humidity.

Multizone AHUs are typically controlled by a central HVAC controller or thermostat, which monitors and adjusts the temperature and humidity of the air being distributed by the AHU. The controller or thermostat may also be used to control the flow of air to the different zones or areas being served, depending on the needs of the space and the system configuration.

  • In addition to distributing conditioned air to different zones or areas within a building, multizone AHUs may also have the ability to modulate the airflow rate based on changes in the load on the system. This can help to improve the efficiency of the system by reducing the amount of energy needed to condition and distribute the air.
