BACKGROUND OF THE INVENTIONThis invention relates generally to the field of air conditioning and more specifically to an apparatus and method for the cooling of ambient air in outdoor spaces
In many regions across the world children and adults participate in amateur athletic events under extremely hot and humid conditions. Usually, the only relief provided from the heat and humidity is the shade provided by canopies, tents, awnings, dugouts or other semi-enclosed spaces. These semi-enclosed spaces have no apparatii for providing any cooling other than the shade provided. Medical tents at such events as triathlons and marathons where heat related illnesses are treated are rarely cooled by any means. Likewise, other entertainment/leisure activities which take place on patios, decks, courtyards or other semi-enclosed places usually take place without the benefit of any cooling mechanism. Traditional air-conditioning systems are designed to cool fully-enclosed spaces by gradually removing the hot air, cooling the air and returning the cooled air to the enclosed space. The efficiency of these systems is largely dependent upon the space being completely and tightly enclosed. These systems also require large electrical energy inputs to run their compressor/condenser and blower components.
Traditional air-conditioning systems, because of their large energy requirements and inefficiency in semi-enclosed spaces have heretofore not been widely used in semi-enclosed spaces such as canopies, tents, patios, decks and courtyards. Fans are sometimes used in such spaces but merely circulate ambient air and provide cooling only by accelerating evaporation of perspiration on the skin; even this effect is limited in humid environments. Evaporative coolers, like fans, require relatively small energy inputs, but, like fans, have limited cooling effect in the many regions that have high humidity levels.
The vortex tube as disclosed by Ranque in U.S. Pat. No. 1,952,281 is a device which separates the energy of compressed gas into a cold air fraction and a hot air fraction. The vortex tube has had industrial applications such as providing spot-cooling in small but critical areas of manufacturing processes, as well as providing cooling within computer cabinets and for other heat-sensitive componentry. These systems have largely been tied to readily available compressed gas systems within the manufacturing/industrial context and have, therefore, not been portable. The prior technology has not addressed the use of the cold fraction discharge of the vortex tube in the context of providing cooling for leisure and recreational activities in semi-enclosed spaces.
BRIEF SUMMARY OF THE INVENTIONThe primary object of the invention is to provide an inexpensive and efficient means of cooling outdoor spaces, particularly enclosed and semi-enclosed spaces such as canopies, tents, patios, decks and courtyards.
Another object of the invention is to provide a lightweight portable device for cooling outdoor spaces that can be transported in a mini-van or light-duty pick-up truck.
Another object of the invention is to provide a lightweight portable device for cooling outdoor spaces, mounted on pneumatic tires, that can be easily pulled by hand to the site to be cooled.
A further object of the invention is to provide a lightweight portable device for cooling outdoor spaces that is powered by re-chargeable deep-cycle batteries that are re-charged by flexible solar panels that are attached.
Yet another object of the invention is to provide a lightweight solar powered device for cooling outdoor spaces that does not use chemicals that are harmful to the environment.
Still another object of the invention is to provide a lightweight solar powered device for cooling outdoor spaces that emits no harmful gases or chemicals and produces, as by-products, only hot air and condensate.
Another object of the invention is to provide a pollution-free means of cooling outdoor spaces utilizing portable compressed air and a vortex tube.
