Air handling units, or AHUs, are essential components of heating, ventilation, and air conditioning systems. AHUs are responsible for circulating and filtering air within a building to ensure a comfortable and healthy indoor environment. These units are typically located within mechanical rooms or on rooftops and can be quite large in size. An AHU consists of a fan, heating and cooling coils, filters, and sometimes humidifiers or dehumidifiers or other components.
A custom air handler is a type of air handling unit that is designed and built to specific requirements or specifications. Custom air handlers are typically used in situations where standard air handling units are not suitable or where a more specialized design is required. For example, a custom air handler may be needed for a large commercial or industrial facility with unique ventilation requirements, or for a building with an unconventional layout or architecture.
Custom air handlers can be designed to meet specific airflow, filtration, and humidity control needs, and may include features such as specialized filters, humidifiers, dehumidifiers, and energy-efficient motors. They may also be designed to operate in extreme temperatures or environments, or to meet specific energy efficiency or sustainability goals.
The fan within the AHU draws in outside or mixed air and circulates it through the system, allowing for proper air distribution. Heating coils within the unit warm up the air during cold weather, while cooling coils cool the air during hot weather. Filters within the AHU remove dust, allergens, and other pollutants from the incoming air, providing clean air to the building. Some AHUs also have humidifiers that add moisture to the air, while others have dehumidifiers to remove excess moisture.
AHUs are controlled by a central control system that regulates the temperature, humidity, and air flow within the building. The control system can also monitor air quality and adjust the AHU operation accordingly.
In commercial buildings, multiple AHUs are often used to serve different areas or floors of the building. These units work together to maintain a consistent temperature and air quality throughout the building. AHUs play a crucial role in maintaining a comfortable and healthy indoor environment for occupants. They help remove airborne contaminants, control humidity levels, and provide proper air distribution. Regular maintenance and cleaning of AHUs are necessary to keep them functioning efficiently and prevent any potential issues.
