Here you see the air-con. The noise spec for this service is NC-20. The air supply arrives through the trunking at the back of the room and is split at the manifold into six feeds. These feeds snake to the front third of the room where they are connected to a plenum. The effect is that the air gently washes out of the plenum across the width of the room and with no noise. It is in front of the front row of seats to avoid dumping air onto viewers seated there.
On the side walls you can see the return-air pipes - these are mirrored on the opposite wall.
