AHU working Principle | English | Animation

An Air Handling Unit (AHU) is a crucial component in HVAC (Heating, Ventilation, and Air Conditioning) systems that regulate the air quality and temperature within a building. AHUs work by circulating and conditioning the air, including cooling or heating it, filtering it, and distributing it to different areas of a building through a network of ducts.

AHUs are made up of several components, including fans, filters, heating or cooling coils, humidifiers or dehumidifiers, and control systems. The fans in AHUs draw in outside air or recirculate indoor air, which is then filtered to remove impurities such as dust and pollen. The air then passes over the heating or cooling coils, where its temperature is adjusted to the desired level. If necessary, humidifiers or dehumidifiers can also be used to regulate the humidity levels in the air.

The control systems in AHUs are responsible for monitoring the air quality and temperature, and adjusting the AHU's operation accordingly. This can include adjusting the fan speed, adjusting the temperature of the heating or cooling coils, or turning on humidifiers or dehumidifiers.

AHUs are used in a wide range of buildings, including offices, hospitals, schools, and industrial facilities. They are essential for maintaining a comfortable and healthy indoor environment, by providing fresh air, regulating temperature and humidity levels, and removing pollutants from the air.

Overall, AHUs play a critical role in HVAC systems, and are an important part of maintaining a comfortable and healthy indoor environment.
