The ATS® innovative solution
ATS® has produced the World’s First Air-Conditioned Open Stadium, the “Al Sadd Stadium” in Doha, Qatar. A very successful Outdoor Cooling Project. This diffusion stadium air conditioning system offers full climate control 20°C (68 °F) over the play yard, giving players the best possible conditions for competition.
In addition to controlling environmental conditions across the play yard, this design also included air conditioning for thousands of seats in the spectator area.
Instead of making a vertical diffusion from the top, horizontal jet streams were used to create a diffusion process in the unused space beside the playing field at ground level.
In the new system, the diffuser jets mix the conditioned air with the ambient room air by entrainment. This "Diffusion Process" reduces the air velocity and equalizes the air temperature. This diffusion process creates relatively uniform air velocity, temperature, humidity, and air quality conditions in the occupied zone.
Spectators in any of the 13,500 seats can also enjoy the matches in comfort. Finished in 2008, this technology assisted Qatar in winning the bid for the 2020 FIFA World Cup, proving that the Gulf region can compete with any other location for global events. Currently, most of the national Qatari matches take place in the stadium, as well as many other sporting and cultural activities. What some may have thought to be impossibility years ago, ATS was very successful at creating an air condition system that works efficiently and completing this outdoor cooling project.
