What is an Air Handling Unit?

AHU Replacement

An air handling unit (AHU) is a device that conditions and circulates air as part of a heating, ventilating, and air-conditioning (HVAC) system. An AHU can provide a variety of functions, such as heating, cooling, humidifying, dehumidifying, filtering, and distributing the air to different spaces. An AHU helps improve indoor air quality, comfort, and energy costs by controlling the temperature, humidity, and air quality.

How can an AHU save you money? 

An air-handling unit saves you money in so many ways. It can reduce energy consumption by controlling the temperature of the air whilst maintaining desired humidity levels, thus saving you money on your bills. It can also reduce maintenance costs by ensuring the air is filtered and contaminant-free, reducing the risk of costly repairs or replacements. Additionally, air handling units can reduce the energy used to heat or cool an area by using advanced insulation materials to prevent energy loss. All of these factors can help reduce overall energy costs and save money in the long run.

 

How do Air Handling Units work?

Consisting of a fan, a filter, a coil, and a heat exchanger, Air Handling Units (AHUs) are devices used to control the temperature, humidity, and air quality within buildings. The process is simple: 

• The AHU draws air from the building into the unit 

• The filter traps airborne particles such as dust, pollen, and other allergens.

• The coil cools or heats the air depending on the desired temperature.

• The heat exchanger then transfers heat from the air inside the building to the air outside.

• The air is then discharged back into the building, creating a comfortable indoor environment.

AHUs are ideal where there is a flow of people in large areas with limited natural ventilation, such as; convention & exhibition halls, hotels, gyms, function rooms & restaurants. They are also suitable options for hospitals and laboratories.

Where can air handling units be installed?

They are typically installed on the roof of a building, in basements or a mechanical room within a building. 

 

How can I control the humidity in my office building? 

At some point, you will suffer humidity in your building, and the air supply in the building will need to be adjusted. In most AHU’s there is a humidity sensor at the outlet of the supply, which measures the moisture in the supply air; this will also have a setpoint for how much moisture should be in the air. You can further eliminate moisture by limiting the number of plants in your building.
