Abstract
PURPOSE: In a device for interrupting aerodynamically the exchange of inside and outside airs at the entrance of a building or a room, to increase the interruption effect and make it possible to reduce the required quantity of energy.
CONSTITUTION: A pair of blasting ports G1 and G2having an opening angle of about 60W70 degrees from an edge wall E1 inclined about 10 W20 degrees to another edge wall E2 inclined similarly about 80 degrees in a direction confronting wind pressure as viewed from an opening surface A of the entrance are confronted along vertical rails 1 and 1' of the entrance, whereby the terminal end of the streamline of an air stream flowing out of both blasting ports G1 and G2 is caused to coincide with a direction confronting said air pressure. That is, the air stream H2 flowing out of blasting ports G1 and G2 confronts in an exactly opposite direction to an air flow H1 making ingress in the interior from the exterior, and the air pressure from the interior is balanced to the pressure of air making ingress from the outdoor side. Therefore, the pressure of intruding air which is going to pass through the entrance is cancelled.
