BACKGROUND OF THE INVENTION

[ 0002 ] Conventional technology, such as fluorescent lighting, has been used in combined manner in the industry to communicate with air conditioning systems. LED lights have also been employed, in combination with an air conditioning system, by adding a "chilled or heated air" duct connection to the panel.

[ 0003 ] There is currently a need for more efficient and environmentally friendly air conditioning systems. These improved systems may be based on water or emulsion loops for the distribution of heated or chilled water.

BRIEF SUMMARY OF THE INVENTION

[ 0004 ] The embodiments described herein provide for a combined light and air conditioning fixture. This system will be cost efficient to produce, on a large or small scale, and will utilize a flexible distributed air handler than can achieve the best, state of the art interface efficiency at a low cost.

[ 0005 ] The disclosed invention may utilize distributed heat exchangers to a liquid loop, where only one main liquid loop is required, an evaporation cooling tower technology may be employed, and the simultaneous heating and cooling in a large application can be achieved using a minimal amount of energy.

DETAILED DESCRIPTION OF THE INVENTION

[ 0017 ] The disclosed embodiments describe a cost and energy efficient combined lighting and air conditioning fixture. This system may utilize a flexible distributed air handler that can employ distributed heat exchangers to a liquid loop. The liquid loop may only require a singular loop, employ evaporation cooling tower technology, and simultaneous heating and cooling in a large application can be achieved using a minimal amount of energy.

[ 0018 ] An exemplary embodiment may be comprised of distributed dampers, heat exchangers, and air handlers that are controlled from a controller integrated into a ceiling, floor, or wall unit. The controller may also be part of a combined LED lighting drop-in ceiling fixture.

[ 0019] In another embodiment, the fixture integrates an Air Handler or Air- Damper with an LED lighting fixture in form of a 2' x 2', 2' x 4', 60cm x 60cm, or 60cm x 120cm drop in ceiling panel.

[ 0020 ] In yet another embodiment, the combined LED and Air Outlet has a motor driven damper that can shut, partially or fully open an air vent. The motor is driven by the LED driver power supply. The air damper will open or close depending on a thermostat measuring the room temperature by averaging inlet and outlet air temperature.

[0021] The heat exchanger of some embodiments will utilize a unique

construction of heat or cold transport and an opposite side air interface will be employed. In some embodiments, the heat exchanger may come in the form of an extrusion that in itself has a shape that incorporates appropriate surfaces and structural features to allow integration of heat transport pipes, fans, drip tray and water connections to be easily adapted. The length of the extrusion will determine the BTUs that can be transferred at a certain air to extrusion temperature difference.

[0022] This device may be easily mass produced with a high degree of automation using a small amount of natural resources while promising a life time of about 3 to 4 times that of conventional technology, namely state change refrigeration units using Freon, R22, Propane or similar gases.

[0023] The device may also be used for cooling and heating by means of electronic control of the solid state heat pump. The unit can combine dehumidifier, drip tray, and condensed water removal via miniature pump.

[0024] In some embodiments, algorithms may be employed to protect solid state heat pumps from operating outside safe envelopes will also act to elongate total unit life.

[0025] It is not possible to extrude small cavities in Aluminum or Copper, which would be requi ed to increase the surface area the water, emulsion, or other substance would be able to have contact with in order to pass with maximum contact to allow minimizing the number of cavities. The would also l imit liquid flow to the minimum as moving the media costs pump energy, thus further reducing the running costs of an air conditioning system.

[0026] In some embodiments of the disclosed invention, the cavity is bigger than ideal. The larger cav ity is achieved by inserting a plastic or other extruded filler so that the water has to squeeze into the small cavity around it, making perfect contact with the walls of the device for optimal heat transfer from the solid to the medium.

[0027] The drip tray, air channels, and fins are al l in one extruded unit allowing modularity. By cutting, for example, units in 2' ,4', or 8' lengths, a 1000, 2000 or 4000 BTU capable air transfer unit can be produced.

[ 0028 ] The present invention is well adapted to attain the ends and advantages mentioned as well as those that are inherent therein. The particular embodiments disclosed above are illustrative only, as the present invention may be modified and practiced in different but equivalent manners apparent to those skilled in the art having the benefit of the teaching herein. Furthermore, no limitations are intended to the details of construction or design herein shown, other than as described in the claims below. It is therefore evident that the particular illustrative embodiments disclosed above may be altered or modified and all such variations are considered within the scope and spirit of the present invention. Also, the terms in the claims have their plain, ordinary meaning unless otherwise explicitly and clearly defined by the patentee.
