A single zone air handling unit (AHU) is a type of HVAC system that is designed to serve a single zone or area within a building or other enclosed space. Single zone AHUs are typically used in smaller buildings or spaces, where the heating and cooling needs are relatively consistent and it is not necessary to divide the space into multiple zones.

In a single zone 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 space being served by the AHU through a network of air ducts.

Single zone 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.

Single zone 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 space being served, depending on the needs of the space and the system configuration.

• In addition to distributing conditioned air to a single zone or area within a building, single zone 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.
