• Airport Terminals

Airports generally consist of one or more terminal buildings, connected by passageways to departure gates. Many terminals have telescoping loading bridges connecting the departure lounges to the aircraft.

The aim of any ventilation system should be to create a positive internal pressure that will prevent the odour and pollutants from entering the terminal buildings.

Terminal buildings have large open circulation areas; check in facilities retail outlets, offices and ancillary areas.

As occupancy can vary considerably through the day, it is important that the ventilation system is able to respond to the changes in occupancy.

Since climatic variations affect the thermal load and in turn the air movement and ventilation performance within a terminal building, the ventilation design must take into consideration winter and summer design conditions for both the central concourse, as well as the perimeters of the building, and thus derive an assessment of the likely thermal comfort and the percentage of occupants satisfied.

Ventilation systems can be designed with recirculation (to provide heat reclaim), controlled by air quality detectors, thereby automatically reacting to passenger flows.

The system design should also incorporate sufficient zone control to accommodate the widely varying occupancy levels in different parts of the building, or even between adjacent departure gates. The availability of information indicating the passenger movement from departure and arrival are useful in estimating the design occupancy levels.

Elta Fans provide a wide range of ventilation products to meet the specific requirements for airport terminal buildings, from car park ventilation to departure lounges, public lavatories, restaurants, lounges, check in gates, staff quarters and other parts of the building, so for more information, please look at examples of typical products that could be used for these applications, or alternatively, please contact us to discuss your specific application requirement.
