So, what exactly is an air handling unit? Simply put, an air handling unit is a device that is used to circulate and condition the air in a building. It consists of a number of components that work together to supply, treat, and distribute the air as needed. These components can include filters, coils, fans, and dampers, among others.
One of the main functions of an air handling unit is to bring in fresh outdoor air and mix it with the indoor air to maintain a healthy and comfortable indoor environment. The unit is equipped with filters that remove any contaminants or particles from the incoming air, such as dust, pollen, and other pollutants. The filtered air is then cooled or heated, as needed, using a coil that is filled with refrigerant. The cooled or heated air is then distributed throughout the building using a fan.
In addition to supplying fresh air, air handling units also play a key role in ventilating a building. Proper ventilation is essential to remove any excess moisture, odors, or other contaminants from the indoor air.
Without proper ventilation, the indoor air can become stagnant and unhealthy, leading to issues such as mold growth or poor air quality. Air handling units ensure that the air inside a building is properly circulated and refreshed, improving the overall indoor air quality.
