PCT No. PCT/SE79/00218 Sec. 371 Date Jun. 25, 1980 Sec. 102(e) Date Jun. 12, 1980 PCT Filed Oct. 25, 1979 PCT Pub. No. WO80/00858 PCT Pub. Date May 1, 1980.Air condition control for buildings, having a roof structure of roof trusses relatively widely spaced, between which self-supporting roof plates are laid and covered by a covering layer so that a gap is formed between the covering layer and the roof plates. Air is passed in one or the other direction through a ventilation opening in the roof, through the air gap (13) and through ducts (9) in the roof plates. Air sucked in from the atmosphere through the ventilation opening passes through the ducts to an air conditioning unit (5) and to a distribution device (6) to maintain a suitable temperature in the building. Air flow can also be inverted by being supplied in the form of outdoor air to the air conditioning unit (5) and after its passage through the building being conducted away into the atmosphere through the roof structure by the ventilation opening. |
