Roof mounted stable ventilator - has structure with sloping internal guides and wind deflectors forming mixing chambers for swirling flow

摘要

The ventilation system for a stable uses a roof mounted ventilator designed to ensure a good extraction of stable air by generating an upward draught under widely varying atmospheric conditions. At the top of the sloping roof is a central opening between side guides (DPL) which slope inwards to narrow the opening at the top. Smaller guides (F) which slope outwards in the opposite direction are mounted adjacent to their top edges. The induced draught is then guided by adjustable flaps (S) to travel sideways resulting in a swirling action under a sloping cover above the gap, for discharge through outer vents in an upper housing with sloping sides (W) forming wind deflectors. These have a narrow opening underneath to allow air to enter and mix with the swirling flow inside their mixing chambers (1).
