Air handling units, also known as AHUs, are an essential part of modern HVAC systems. They are responsible for controlling the air quality and temperature within buildings, making them a crucial component of any commercial or industrial space.
AHUs consist of various components that work together to condition the air within a building. These components typically include fans, filters, heating and cooling coils, and sometimes humidifiers or dehumidifiers. The main function of an AHU is to draw in air from the surrounding environment, filter it to remove contaminants, and then distribute it throughout the building.
Functions of AHU
One of the most vital functions of an air handling unit is to regulate the temperature of the air within a building. This is typically done through the use of heating and cooling coils that warm or cool the air as needed. By controlling the temperature, an AHU can help to maintain a comfortable working or living environment, regardless of the outdoor conditions.
Another crucial task of an AHU is to regulate the humidity levels within a building. This is particularly important in spaces where sensitive equipment or materials are stored, as fluctuating humidity levels can lead to damage or deterioration. To achieve this, an AHU may be equipped with a humidifier or dehumidifier, which controls the amount of moisture present in the air.
Lastly, an AHU must also filter the air to remove any pollutants or particulate matter. This is done through the use of high-efficiency filters that trap particles as small as 0.3 microns. By removing these contaminants, an AHU can help to improve indoor air quality and protect the health of those within the building.
