Abstract:
A sliding door:with two outer side pieces extending from a building wall and surrounding a building entrance/exit; with at least one outer moving panel associated with the two outer side-pieces which closes or opens an entrance/exit as a result of its movement into a closed or open position; and with a ventilation system which, by means of at least one blower nozzle that is located so that it can be pivoted to face toward either one of the interior and exterior of the building, blows air into the building entrance/exit area; wherein the at least one blower nozzle is coupled with an air speed indicator so that a pivoting angle of the at least one blower nozzle can be adjusted as a function of the outside pressure on the outside of the building as measured by the air speed indicator, or the quantity of air discharged from the at least one blower nozzle is varied; the sliding door is a curved sliding door, and the outer side-pieces and the outer moving panels are curved; there are two inner side-pieces that run into the interior of the building and are adjacent to the outer side-pieces, whereby at least one inner moving panel is associated with the inner side-pieces; and the opening degree of at least one of the at least one outer moving panel and the at least one inner moving panel can be set as a function of the outside pressure measured by the air speed indicator.
