STADIUM WITH ARENA SUCH AS AN ICE RINK AND SURROUNDING STANDS FOR SPECTATORS, AND CHANNEL ELEMENT FOR A CHANNEL SYSTEM IN A STADIUM SUCH AS AN ICE RINK AND SURROUNDING STANDS FOR SPECTATORS
STADIUM WITH ARENA SUCH AS AN ICE RINK AND SURROUNDING STANDS FOR SPECTATORS, AND CHANNEL ELEMENT FOR A CHANNEL SYSTEM IN A STADIUM SUCH AS AN ICE RINK AND SURROUNDING STANDS FOR SPECTATORS
The invention relates to a stadium with an arena (1) such as an ice rink, and surrounding stand (2) for spectators, and to a channel element for a channel system in the arena (1) and the surrounding stand (2). The arena (1) and the stands (2) comprise a channel system each, arranged so that air may be supplied and/or extracted for cooling or heating the arena (1) when the arena (1) is to be iced or de-iced, or so that the stands (2) may be used for heating and/or cooling of the stadium, respectively. Each channel system is made up of a number of channel elements consisting of at least three interconnected layers (3, 4, 5) of corrugated sheet material. The layers (3, 4, 5) are placed at angles in proportion to each other in such a way that corrugations of layers placed one above the other are preferably mutually perpendicular. Thereby channels are formed by the corrugations of the layers (3, 4, 5). The channels are interconnected by the intermediate layer (4) being formed with a number of holes (6) extending transversely to, and preferably in a plane through, the mid portion of the layer (4), so that air at a temperature providing heating and/or cooling may be taken through the formed channel system in a controlled manner.
