The Air-conditioned Stadiums of Qatar World Cup

Qatar is of a tropical desert climate, which is only divided into summer and winter.
The temperature there in summer is up to 43 ℃, which is not suitable for football matches. Therefore, the 22nd World Cup was adjusted to winter. But even in winter, that is, this month, the highest temperature there every day exceeds 30 ℃. In order to maintain a comfortable temperature in the stadium, Qatar has developed innovative stadium cooling technology to enable competitions to be held even throughout the year.
Qatar World Cup venues, except for the movable 974 stadium, all other stadiums are equipped with a "heroic" cooling system. In addition, the top of the venue is mostly made of light colored materials to maximize the reflection of solar radiation and avoid absorbing too much heat. This simple color change can reduce the internal temperature of the stadium by 5 ℃! In order to achieve the goal of comfort and energy conservation, the range of cooling needs to be further reduced. After all, there is no need to cool the whole stadium, just the area where the spectators and athletes are located (about two meters above the ground). Dr. Cool calls it targeted or spot cooling - "targeted cooling" or "local areas cooling", which depends on the new cooling system including Heatsinks supporting the stadium.
Different from our familiar household air conditioning system, this cooling system included Extruded Heat Sinks can use solar energy to drive and use circulating water as the medium to cool the water to 7 ℃ and store it to cool the air in the stadium. The purified and cooled air is sent to people by the grille under the bleachers seats and the big nozzle around the stadium. The turbid waste gas is pumped away through the air circulation system for recovery, re cooled and filtered, and then re fed, so on. Therefore, it is only necessary to turn on the air conditioning system two hours before the start of the game, so that the audience and players can experience the wonderful game in a cool and comfortable environment of about 24 ℃.
This cooling technology is very innovative, and it's an open example for other countries in the world to learn from.
Suprel company are very excited to read about this news on how Qatar cool temperature for the world cup stadiums. For years and we have been hard-worked with our extrusion on Heat Sink Types and machining technicians to create innovations as well for metal parts processing, so that we can provide more values to reduce the cooling costs for our clients.
