Air quality management in airports is as challenging and complex as air traffic control
Millions of people per year travel by air
Airport terminals are confined spaces where the HVAC system is very important in order to obtain and maintain a comfortable indoor environment. Large CAIRplus units with optimised filter systems and environmentally friendly and cost reducing energy recovery systems are an optimal solution to guarantee a pleasant space for occupiers.
Depending of the climate and the season the outside temperature can be utilised for cooling by simply increasing the flow of outside air. Heat recovery systems are another good way of saving energy, using excess heat as thermal energy as opposed to being vented outside.
It is recommended to employ demand control ventilation in all multi-occupant spaces, like ticketing areas and hold-rooms, so that the supply of conditioned outside air can be provided based on the constant variation in occupancy. This will allow, for example, the system to cycle down fans and motors when hold-rooms are not occupied, but ensure that an ample volume of conditioned outside air will be provided when these and similar spaces are at peak occupancy.
Another important element for more efficient running is a good monitoring of the complete system. Faults can be identified and put right earlier as well as the external conditions being monitored to ensure that HVAC systems are powering down when appropriate.

These cookies are necessary for the specific functions of a website to be carried out. For example, such cookies are used when a user puts a product in the shopping cart and then continues to surf the site (or other sites) before proceeding to checkout. This means that his shopping cart is not deleted even after closing a browser window.
These cookies collect information about the behavior of users on the site and whether users receive error messages (if so, where and after which events). Loading times or the behavior of the website with different browser types are also measured with performance cookies.
These cookies are not absolutely necessary, but increase the "usability" of a website. For example, the location entered once is saved so that the respective user can immediately see this location when the page is called up again. Form data that have been entered, the size of the font or the like, can also be saved.
Advertising or targeting cookies are explicitly there to show the user advertisements that match their surfing behavior. You often notice the use of these cookies after you have been to online shops: Advertisements for this shop reappear on many websites visited afterwards, sometimes with a (deliberate) delay of a few hours to a few weeks. In online marketing, this is also called "re-targeting".
