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 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.
A system for controlling temperatures in a stadium having an arena (1), on which water may be frozen and thawed, and a surrounding stand (2) which is heated or cooled for the comfort of spectators, said system comprising a first channel assembly mounted in heat transfer relationship with the arena;
A channel assembly for a channel system for controlling temperatures in a stadium by circulating air between an arena (1), on which water may be frozen and thawed, and a surrounding stand (2) which is heated or cooled for the comfort of spectators, said channel assembly comprising at least three generally contiguous layers (3,4,5) of corrugated sheet material, said generally contiguous layers being arranged in a stack having a pair of exterior layers separated by an intermediate layer, the orientation of the corrugations in one layer being perpendicular to the orientation of the corrugations in any adjacent layers for forming a plurality of channels in said generally contiguous layers, said intermediate layer being perforated throughout the extent of the intermediate layer to interconnect the channels of said generally contiguous layers and to allow air supplied to the channel assembly to circulate through the channels in said generally contiguous layers.
