Types of Air Handling Units - AHUs Explained

Air handling units (AHUs) are essential components of HVAC systems that are responsible for conditioning and circulating air in a building. AHUs come in various types, each with unique features and benefits designed to suit specific applications. In this article, we will discuss the different types of AHUs and their characteristics.

Packaged AHUs

Packaged AHUs are the most common type of AHUs used in commercial buildings. They are designed for indoor installation and are often used in locations where space is limited. Packaged AHUs are compact and consist of all necessary components, including the fan, filters, heating or cooling coils, and controls. They are easy to install and maintain, making them a popular choice for HVAC contractors.

Rooftop AHUs

Rooftop AHUs are installed on the roof of a building, making them ideal for buildings with limited indoor space. Rooftop AHUs are typically used in larger commercial buildings and are designed to handle larger air volumes. They are also easier to maintain since they are located in an accessible location.

Modular AHUs

Modular AHUs are a type of packaged AHU that consists of several pre-engineered modules that can be assembled on-site. Modular AHUs are a popular choice for large commercial buildings where space is limited or where the installation of a traditional packaged AHU is not possible. They are also easy to maintain, as individual modules can be removed and replaced without affecting the overall system.

Heat recovery AHUs

Heat recovery AHUs are designed to recover and reuse heat from the air that is being exhausted from a building. Heat recovery AHUs are used in buildings where temperature control is critical, such as hospitals and research facilities. They can help reduce energy costs by using recovered heat to preheat the incoming air.

Energy recovery AHUs

Energy recovery AHUs are similar to heat recovery AHUs but are designed to recover both heat and moisture from the exhaust air. They are ideal for buildings in hot and humid climates where maintaining indoor air quality and reducing energy costs are essential.

Cleanroom AHUs

Cleanroom AHUs are designed for use in environments where air quality is critical, such as research facilities, pharmaceutical labs, and hospitals. Cleanroom AHUs are equipped with HEPA filters that can remove airborne particles as small as 0.3 microns. They are designed to provide a high level of air cleanliness and can maintain a controlled environment.

Outdoor AHUs

Outdoor AHUs are designed for use in harsh outdoor environments, such as industrial plants, wastewater treatment facilities, and power generation plants. Outdoor AHUs are designed to withstand extreme weather conditions and are often made of heavy-duty materials such as stainless steel or aluminium.
