ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to skylights and, more specifically, to a modular skylight and solar fan combination unit that will allow the installer to install both a skylight and a solar fan into a single rough opening. The present invention cost effectively increases the comfort and health of persons inside of structures in which it is installed.
It is critical to provide a means for accumulated heat to be removed from the uppermost portions of a house or building to prevent heat build-up and to assure adequate air quality therein. Poor air quality not only compromises the comfort level therein but poses significant health risks to the inhabitants thereof due to mold and other such conditions. Static vents are frequently used but are limited in their effectiveness particularly during the summer months or in warmer climates. Electric fans are also used for venting and have been found to efficiently remove a substantial amount of air to reduce the interior ambient temperature but are costly as they rely on the external power supplied to the building structure and also require running electric wires thereto which is labor intensive and could add significantly to the installation cost thereof when being installed in an existing finished structure. Lowering the interior ambient temperature greatly reduces the reliance on air conditioning systems but the cumulative power demands of a properly ventilated community using electric fans still places an unnecessary burden on the local utility which could be critical in times of extreme heat when communities often face brownout or even blackout conditions.
Skylights are frequently used to introduce natural ambient light into dwellings and serve to further reduce the reliance on power provided by public utilities but frequently increase the temperature therein by acting essentially as a magnifying glass. The present invention addresses this concern by utilizing a dual-domed skylight wherein the outer dome is comprised of a white translucent acrylic for reflecting the heat from the sun and diffusing and softening the light entering therethrough whereas the inner dome is a transparent acrylic and operates conjunctively with the outer dome to form a thermal barrier that minimizes the heat exchange from the atmosphere into the interior of the room.

A cooling structure having an insulated floor, an outer wall, an outer roof, an inner wall extending upward from the floor and spaced from the outer wall, an inner roof associated with the inner wall to thus provide an air circulating space between the outer an inner walls and the outer and inner roofs, a chamber into which said space opens having louvers, ventilators disposed in the floor and ventilating pipes extending up from the inner roof and extending exteriorly to the outer roof and having a damper.

Inventor: Malcolm H. Nickerson et al.
Issued: Oct. 4, 1977
Apparatus and method for venting moisture from the interior of an enclosed space to atmosphere while restricting the flow of ambient moisture back into the enclosed space. A chamber is provided in fluid communication with the substantially enclosed space. Means are provided for absorbing solar energy for heating the interior of the chamber when the chamber is exposed to sunlight. A first pressure sensitive valve is effective to vent moisture, liquid or other fluids from the chamber to atmosphere and to block flow between the chamber and the substantially enclosed space during the periods when the chamber is exposed to sunlight. A second pressure sensitive valve blocks flow of ambient air into the chamber and vents moisture or other gaseous material from the substantially enclosed space to the chamber during periods when the chamber is not exposed to sunlight. The method, according to the present invention, comprises the steps of venting moisture from an enclosed space into a chamber during periods where the chamber is not exposed to sunlight, sealing against backflow of gaseous material from the chamber to the enclosed space and venting the chamber to the atmosphere during periods of heating of the chamber by the sunlight to thereby vent fluid material from the enclosed space to the atmosphere.

Issued: Feb. 21, 1984
A roof vent for flat built-up roofs, having a truncated pyramid-shaped air stack with a protective cap and an internal fan for inducing upward air flow through a check valve at the upper end of the stack. A solar panel provides power for operating the fan, a thermal switch is employed for enabling the fan above an ambient temperature of 50 degrees F. (10 degrees C.) and a humidistat may be employed for disabling the fan below 50% relative humidity.

A ventilation system for a motor vehicle such as an automobile includes a ventilating hole defined in a body of the motor vehicle for venting an interior of the body to atmosphere, and an aerodynamic device such as an air spoiler mounted on the body at the ventilating hole and having a lower surface held against an outer surface of the body, a front surface for forming a negative angle of elevation with respect to an air current flowing along the body while the automobile is running, and a rear surface for separating the air current off said body. The aerodynamic device has a vent hole extending therethrough from the lower surface to the rear surface in communication with the ventilating hole.

The present invention includes a self-contained personal cooling device. It is a one-piece modular component which is pre-wired and interchangeable between different hats. The components of the modular unit are employed in the unit to effect total body cooling by evaporation and forced convection. The unit is powered by photo-voltaic energy. The cooling effect of this modular device is maximized by incorporating air vent slots adjacent to the fan motor assembly to increase the force of air delivery.

A solar ventilator (
1
) is fittable to an edge (
2
) having first and second sides corresponding to first and second regions. The edge can be of a barrier, e.g. of a movable window of a motor vehicle or of a building. The ventilator has a suspension (
5
) for suspending the ventilator from the edge so that the ventilator will be adjacent the first region. The ventilator has a housing (
4
) having inlet and outlet portions (
11

12
) for enabling air to be transferred therebetween from a region to the other region. A fan (
13
) is comprised by the housing so as to enable the transfer of air. A solar generator (
