PCT No. PCT/SE84/00420 Sec. 371 Date Aug. 12, 1985 Sec. 102(e) Date Aug. 12, 1985 PCT Filed Dec. 10, 1984 PCT Pub. No. WO85/02668 PCT Pub. Date Jun. 20, 1985.Wind guard device for the purpose of sustaining a gentle flow of gas in a gas passageway (6, 8, 11) between a building and the atmosphere surrounding the building and of reducing the wind effect of the atmosphere on the flow of gas, in conjuction with which a heat recovery arrangement (12) for the exchange of heat between the flow of gas and a heat absorbing medium is arranged in the gas passageway. The heat recovery arrangement is provided with a number of birstle-like projections (13) which form between them a number of gas passageways of irregular curved form. Said projections (13) may be heat-conducting and may be connected in a thermally conductive fashion to the heat recovery arrangement so as to increase the thermal absorption capacity of the latter. The heat recovery arrangement may be provided inside the gas passageway in the form of an outwardly inclined jacket, so that the gas which has been cooled by the heat exchange process can fall downwards into the aforementioned area of the gas passageway.
