20150219347 | ROTOR VENTILATOR - A rotor ventilator comprising a ventilator stator for mounting to a structure and a ventilator rotor for mounting and rotation with respect to the ventilator stator is disclosed. The ventilator further comprises a cover for positioning over the ventilator rotor and mounting to the ventilator stator, The cover comprises a central portion surrounded by an outer substantially concave portion. The outer concave portion of the cover may protect the ventilator from environmental conditions/elements, such as by redirecting particles, water droplets, debris and dust, etc away from the interior of the ventilator. The outer concave portion may act as a trough, from which the particles can then be directed off the cover. The trough may also act to prevent the particles from escaping over the sides of the cover, and into the ventilator. | 08-06-2015 |
20150219358 | SYSTEM FOR OPTIMISING AN ENCLOSED SPACE - A system for optimising one or more environmental parameters of an enclosed space comprising first and second relatively enclosed regions, such as a living space and a roof space within a building, is disclosed. The system comprises an internal sensor, in the first region, and an external sensor, external to the enclosed space, for measuring respective environmental parameters. The system also comprises a controller and a diverter valve.

20150226442 | 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. | 08-13-2015 |
