A system to keep football fans and players cool at the 2022 FIFA World Cup, to be held in Qatar, has been officially unveiled at the newly renovated Khalifa International Stadium. The system was used at the recent Emir Cup tournament. It uses approximately 500 jet nozzles to blow cold air to keep temperatures around 23°C for fans in the stands and concourses. Chilled water is piped to the stadium from a cooling center around one km from the stadium to provide the cooling. The designer of the system says, “There isn’t on earth, one [other] open air, air-conditioned stadium,” and adds that the cooling system would use up to 40% less energy than conventional cooling methods.
The stadium was first built in 1976 and recently went through its second renovation.
