This is the reason why the stadiums will have
air-conditioning installed, in order to bring down
the temperature to about 20 degrees on the pitch
and 23 degrees in the stands. The innovation being
trialed in Qatar involves a system where cold air is
being pumped into stadiums through a system
powered by chilled water, which is the transformed
into a cold mist after passing through cooling
nozzles.
They way it works is that the platform of the
stadium is used to defend it against the infiltration
of warm wind. This means the stadium is a barrier
that is basically containing a cold bubble inside.
The technology works by maintaining the cold
bubble for as long as necessary in order for people
to watch the game, and so the players are
comfortable enough to play their game.
The Al Wakrah Stadium also has a roof that can be
opened and a seating-bowl cooling system to allow
football to be played all-year round. At Al Wakrah
Stadium, they are using an air circulation technique,
which means some of the air is drawn back, cooled
again and then pushed back to the supporters and
players.
The cooling technology for the FIFA World Cup
Qatar 2022 has been a crucial part since the country
announced its bid for the tournament in 2009.
Every stadium has it’s own unique form and
structure. For example, the Khalifa International
Stadium is a big stadium with an athletics track
which makes it so an unconventional treatment is
needed. At Khalifa, fresh air is taken and pushed to
the people. Moreover, a new line of under-seat
diffusers has been developed in order to deliver the
air to fans in a gentle manner.
No doubt, Qatar wants to show itself to the world,
building the most advanced stadiums that ever have
been built. The stadiums are also built so close to
each other, fans could actually attend more than one
game per day. The longest distance between two
venues is just 55km, a short journey that will be
seamless thanks to an advanced underground railway
system.
