去年对傀儡在一号球场，下雨暂停，等了半天再盖布。

close.
But the total time for the transfer between outside and inside play can be
up to 45 minutes, with the air conditioning needing time to acclimatize to
indoor play.
The air con dries the grass to prevent slippage and injury.
The speed of the roof closing means that fans don't need to pack wet weather
gear and players don't need to rush off court.

The roof can close in fewer than seven minutes and the shutters can close in
30 seconds. The time it takes to establish a given temperature and humidity
in the stadium depends on the current atmospheric conditions.
Once the roof has closed and the weather-tight seal has activated, air will
be circulated around the stadium to maintain a similar temperature and
humidity as it was prior to the roof closing.
Vents running around the upper bowl determine the flow of air, with laser-
focused vents shooting air to the lower bowl and two other sets of vents
pushing air to the upper deck. It’s important to keep the stadium at
specific temperatures and humidity ranges to stop condensation forming on
the inside of the roof. |
