AIR CONDITIONING SYSTEMS
An air handling unit (AHU), also known as an air handler, is a device used to condition and circulate air in a heating, ventilation, and air conditioning (HVAC) system. It plays a crucial role in maintaining comfortable and healthy indoor environments in residential, commercial, and industrial buildings.
The primary function of an AHU is to take in outside air or return air from the building, condition it by cooling, heating, humidifying, or dehumidifying as required, and then distribute it throughout the building. The AHU consists of several components that work together to achieve these tasks:
-
Filters
-
Heating and Cooling Elements
-
Humidification and Dehumidification Components
-
Fans
-
Mixing Chamber
-
Controls and Sensors
AHUs are typically designed to meet the specific requirements of the building they serve. They can vary in size, capacity, and complexity, depending on the building's size, purpose, and HVAC system design.
