Air handling units explained: everything you need to know

Here at Australian Climate Agencies, we are experts in air handling units—we would like to share our knowledge with you so you can confidently decide on the best option to suit your needs. Have a read below as we explain the different types of air handling units.

The purpose of an air handling unit

Air handling units take fresh air from outside to distribute within the inside of a building. Once the outside air has been captured, the air handling unit cleans it, heats or cools it and will sometimes humidify it depending on the requirements of the building. This air is then taken and distributed via ducts throughout the inside of the building. Many units will have an additional duct that pulls air from inside of the room to clean and then redistribute again later.

The purpose of an air handling unit is to clean air so that it maintains satisfactory indoor air quality levels and that it is safe to breathe. Air handling units may also be used for removing humidity from an indoor area. Not only are air handling units essential for air quality, but they are also helpful when it comes to saving energy as they recycle the same air into a space.

Different types of air handling units

Over the years, there have been various air handling unit designs introduced. The two main types of air handling units are constant air volume and variable air volume. The variable option regulates the volume of supply depending on the level of cooling or heating that is required. This means that the energy consumption can be reduced as the fan is used less and there is overall less wastage.

Here at Australian Climate Industries, we only work with trusted brands in air handling including Calorex and Weger. If you require further information on the different types of air handling units and what would best suit your requirements, our team of experts are here to assist.

What are the best air handling units?

For energy efficiency and cutting costs on power, it is generally recommended that property owners opt for a variable air volume unit. Many factors are going to affect the efficiency of an air handling unit and determine which is right for a particular building, for example, the size of a building and where it is located.

Today, most modern office buildings are served by variable air volume units. This is generally because most have HVAC loads that vary depending on the season and the occupancy levels. This means that a variable type system will be a more efficient option when operated correctly.
