Air Handling by S&P: What are Air Handling Units and Why are they Important?


Ventilation systems are essential for maintaining a healthy and comfortable indoor environment, especially in commercial or industrial buildings. Air handling units can play a critical role in these systems, making all the difference to the indoor air quality of the building.

Air handling units help to ensure that indoor spaces are comfortable and safe. They can come in all shapes and sizes, each offering a range of benefits dependent on the application.




What is an Air Handling Unit?


Commonly known as an ‘AHU’, an air handling unit is a piece of equipment used to regulate and circulate air in HVAC systems. It consists of a housing unit that contains various components such as fans, filters, heating and cooling coils.


The AHU draws in outside air and then filters and regulates it to meet the requirements of the building or space it serves. It then distributes the filtered air through the ductwork to various zones or rooms.


Why are AHUs Important?


Maintaining Indoor Air Quality


Air handling units help to ensure that the correct level of ventilation is provided for the setting, so that the people occupying the building have sufficient fresh air coming in. Without the required air changes, carbon dioxide and stale air can build up in enclosed spaces and cause problems for the occupants, such as fatigue, headaches, and other health issues.


In addition, air handling units can help to filter the air and remove harmful particles, allergens, dust, and other contaminants that may cause allergies or respiratory issues.


Controlling Temperature and Humidity


Depending on the specification, an AHU can also adjust the temperature of the air as it passes through the system, heating or cooling the air as needed, to provide a comfortable room for the occupants.


Delivering Energy Efficiency


Air handling units can be equipped with a heat recovery system, which uses the heat from the space to warm up the incoming fresh air. This can significantly reduce the amount of energy needed to heat or cool the air, making the ventilation system more efficient.


Providing Bespoke Solutions


Air handling units can often be customised to meet the specific needs of a building or space. For example, an AHU can be designed to incorporate high-level filtration such as a HEPA filter to create a cleanroom environment, such as in a laboratory, or it can be designed for use in areas with extreme environments including coastal or swimming pool areas.
