Air handling units (AHUs) are essential to the operations of a facility. As such, it is the responsibility of the facilities manager to understand the components of an AHU and how they work together. This guide will provide a comprehensive overview of the components of an AHU and how they contribute to the overall system.
What is an Air Handling Unit?
An air handling unit (AHU) is a system of components designed to condition and circulate air in a facility. AHUs are typically used in commercial and industrial settings to provide comfort, ventilation, and air circulation. They are also used in laboratory settings to provide air safety. The components of an AHU help to process the air, filter it, and distribute it throughout the facility.
Components of an Air Handling Unit
There are several components that make up an air handling unit, including the following:
Air Filter
The air filter is a crucial component of the AHU system that helps to ensure clean and healthy air for the facility. It is designed to trap and collect dust, dirt, and other particles from the air, preventing them from entering the building and causing health hazards. Air filters should be regularly serviced and changed to ensure optimal air quality.
Heat Exchanger
The heat exchanger is responsible for transferring heat from one air stream to another. This helps to maintain the desired temperature within the facility by exchanging the heat between the incoming and outgoing air streams. Heat exchangers are also used to preheat or precool incoming air before it is distributed to the rest of the building.
Fan
The fan is responsible for moving the air through the AHU system. It helps to ensure that the air is being circulated properly and is distributed to the desired areas of the facility. Fans come in a variety of sizes and designs, depending on the needs of the facility.
Humidifier
The humidifier is used to add moisture to the air in order to maintain a comfortable level of humidity within the facility. This helps to reduce static electricity, prevent dust and allergens from becoming airborne, and provide a comfortable environment for occupants.
Heater
The heater is responsible for providing heat to the air stream. This helps to maintain a comfortable temperature within the facility and reduce the amount of energy required to keep the building warm.
Cooler
The cooler is responsible for cooling the air stream. This helps to maintain a comfortable temperature within the facility and reduce the amount of energy required to keep the building cool.
Conclusion
Air handling units are essential to the operations of a facility, and the components of an AHU must be understood by facilities managers to ensure optimal functioning and air quality. This guide provided a comprehensive overview of the components of an AHU and how they contribute to the overall system. By understanding each component and its role in the system, facilities managers can ensure that their AHUs are functioning properly and providing clean, healthy air for the occupants.
