Air handling units are used in a wide range of sectors that require specific conditions in terms of air quality and ventilation. Naturally, cleanrooms require adequate ventilation to ensure that the necessary conditions are maintained inside them. We explain the role of air handling in cleanrooms.
Many factors must be considered when preparing cleanrooms, with air treatment being one of the most important. The room must contain the precise amount of oxygen for the processes to be carried out correctly in the sector that required the construction of this type of space.
Air treatment in cleanrooms must be implemented to ensure perfect overall environmental quality, taking into account factors such as thermal environment, air filtration, air renewal and recirculation, acoustic environment, and lighting.
Here, we highlight the air handling unit (AHU), which is the equipment designed to improve air quality before it is introduced into a cleanroom or any other building. This improvement is achieved through filtration and humidification or dehumidification, and thermal air treatment, commonly known as air conditioning, is also frequently used. Furthermore, they are often placed on building roofs or terraces due to their large size and simplicity.
On the other hand, the design of these air handling systems depends on the specific conditions of each project, so it must be customized and adapted to the client's needs. It's important to know that, in addition to the general requirements that apply to all cleanrooms, regulations applicable to different sectors may impose specific conditions that must be met.
Likewise, another factor we must consider when choosing these systems is the energy consumption of the facilities, since the air handling system itself represents a significant energy expense for the entire plant.
In this way, air handling systems provide a service tailored to each client, hence the importance of their selection for the final balance of the cleanroom project.
An air handling unit is a piece of equipment used to ventilate and purify the air, especially in places that require constant air renewal, ensuring a correct temperature and air purity.
Yes, considering the very specific conditions and characteristics that a cleanroom must have to comply with regulations, ventilation and air quality in the room are fundamental to minimizing the possibility of any type of contaminating particles entering and ensuring the highest possible environmental quality.
The air handling unit first filters the air to remove impurities and then air conditioning it. Once this is done, the system distributes the treated air through the ventilation ducts of the place where it has been installed, whether it is a clean room or other type of room.
There are two types of air handling units, classified by size: compact units and modular units. Compact units consist of a single module for all air treatment, while modular units are larger and more complex.
Air handling units are generally used in enclosed spaces where there is usually a considerable flow of people and, therefore, the air may be of poor quality, or in spaces that require a high level of cleanliness in their environment, such as a cleanroom.
