Ventilation of shooting gallery - involves air inlet in ceiling from which air flows horizontally to target end of gallery

摘要

The ventilation system for a shooting gallery (1) has an air inlet in the ceiling at the end of the gallery (7) from which the shots are fired. The air flow is controlled to produce a laminar flow (12) which flows downwards and is then deflected in the horizontal direction towards the target end of the gallery. This horizontal flow of the ventilating air takes away all smoke, fumes, etc. produced by the firing of the guns and maintains a supply of fresh air to the persons firing the guns. USE - Ventilation of shooting galleries.
