A unique system to keep football fans and players cool in the 2022 World Cup has been revealed at the Khalifa stadium in Qatar.
The stadium, which has been completed five years ahead of schedule of the World Cup, was recently opened and hosted the Emir Cup final between Al Sadd and Al Rayyan.
The new cooling system has been designed by engineers from the University of Sheffield alongside Qatar University and has had to be put in place due to scorching local temperatures. Although the competition has been moved from the summer to November and December, the average temperature during this time still ranges between 25 and 29 deg C.
Dr Ben Hughes’s team from Sheffield’s Energy 2050 institute worked with Qatar University to design the system which cools the outside air and and pushes it through to the pitch, stands and concourse areas through a number of nozzles.
This district cooling technology is more sustainable and environmentally-friendly than air conditioning systems and uses recovered heat in a mixed mode to deliver a stable, comfortable indoor environment.
The 40,000-seat stadium was first opened in 1976 but has undergone extensive renovations for the World Cup.
Dr Hughes said: “One of the main challenges in holding the World Cup in Qatar is maintaining the thermal comfort of players and spectators. By using innovative cooling technology, we are able to reduce temperatures and the energy needed to meet carbon neutral commitments.”
