Qatar World Cup Bid 2022

The Qatari government has become the first country in the region to host a major football tournament. As the tournament was due to take place in June/July high temperatures were a major concern for both players and spectators. The daytime high can be up to 50degC. The average daily lows do not drop below 30degC. A stadium incorporating a controlled temperature system was the answer to the problem.

A 2000 seat showcase stadium has been constructed in Doha to prove innovative cooling technologies. Desiccant DryAir working with the main contractor, designed, manufactured and installed various mechanical systems incorporated into the zero carbon footprint of the project:

  • An innovative 3.5 metre twin desiccant wheel cooling system.
  • High temperature hot water pressurization system element of the parabolic solar farm system.
  • Hot water energy storage system to store energy from the solar farm.

The system can store enough energy to provide cooling for 10 hours, plenty of time for a match to be played even if extra-time or a penalty shoot-out is required. A FIFADelegation visit, noted that the outside temperature was 44degC but a pleasant 23degC on the pitch. On non match days the solar farm channels electricity into Qatars national grid. This offsets the stadiums match day needs for lighting, turnstiles, scoreboards and everything else that makes up a modern sports stadium.
