The heat is no longer a problem: the stadium that in a year will host the World Cup athletics (doing tests in view of those of football) keeps the temperature around 26 degrees when out of the 40 are exceeded thanks to an air bubble cold
t seemed one of the main obstacles for organizing any sporting event in a country where temperatures can easily exceed 50 degrees. But heat is no longer a problem in Qatar. This is demonstrated by the cooling system of the Khalifa Stadium that will welcome the World Championships in a year, doing tests in view of those of football in 2022. As noted by the team, inside the plant is not covered the temperature in fact remains around 26 degrees when outside the 40 are exceeded.
ICE - The solution is based on the concept of the cold air bubble that once created in the stadium effectively rejects the surrounding hot air. All within half an hour. The cold is generated in a two-kilometer system that makes it possible to transform the water, partly recovered from the rare rains, into ice. A nocturnal procedure connected to a sort of underground radiator that turns the ice into the air, which is then fired into the stadium by 300 fillers. The management is entrusted to an information system that allows to adapt the supply of cold air to the disciplines carried out at different points of the track, so as not to disturb the athletes. The engineer Saud Abdul Ghani who created the project explains to the team: "It is a system already integrated at the stages of the 2022 World Cup, adapted to the Khalifa that was built in the '70s, and that allows a saving of 40% of energy compared to a standard model ". For the outdoor races like the marathon instead there are no real alternatives, except maybe organize them at night.
