Roof ventilation system and method

The present invention provides a ventilation system for an attic or rafter space that mimics the appereance of the roofing material and thus has little effect on the appearance of the building. In one aspect primary vents (40, 84) are installed in the roof deck (56, 86) below the roof tiles (91), and the roof tiles (91) are mounted to as to provide air spaces in between them and thus allow air flow (98) from the primary vents (40, 84) to the outside. In another aspect a secondary vent (85, 12) is constructed to look like the surrouding field tiles (91) and is installed over each primary vent (40, 84). One or more vent openings in the secondary vent (12, 85) and an opening in the primary vent (40, 84) conduct air between the attic or rafter space and the outside. The secondary vent (12, 85) has a frame (16) with one or more vent openings and a cap (14) covering each opening shielding the ventilating space.

Ventilation system for an animal house

An animal house ventilation system 1 comprises a roof 2 supporting exhaust chimneys 4 and vents 3 in walls of the house. Some chimneys 4 have both baffles 6 and exhaust fans 7, and other chimneys 5 have only baffles 8 without fans. A controller 10 is linked with sensors including temperature, pressure, ammonia and carbon dioxide and controls the vents, the exhaust fans, and the exhaust baffles. The controller causes the system to operate as a natural ventilation system utilizing the vents and all of the chimneys in the roof as openings for ventilation until a point is reached where there is not enough air movement through the house under natural ventilation conditions. At this stage the fans are started at a low speed and the baffles in the chimneys without fans are closed to ensure that there is no downdraught. The inlet vents continue to open at the same time the fans speed are increased, and continue to increase in speed after the inlet vents have fully opened to keep the temperature ...

Ventilator and blade therefor

A roof-mounted ventilator comprising a plurality of blades is disclosed. Each blade comprises front and back blade faces and leading and trailing edges. When the ventilator is viewed in side profile, the blades are positioned and configured such that a line of sight into the interior of the ventilator is substantially restricted or obstructed. Restricting or obstructing the line of sight into the ventilator can reduce or prevent various particles, such as water droplets, debris, dust and light, from entering the ventilator interior. For example, rain is thereby forced to strike a face of the blades, thus preventing direct access into the ventilator interior. The blade itself may include additional features, such as a lip that extends along the length of the leading edge, to further prevent particles from entering the ventilator interior, or to redirect the particles away from the ventilator interior in a controlled manner.
