Abstract
Description
- The present invention relates generally to air conditioning systems, and more specifically, to a system that improves the performance of a conventional air conditioner by removing the humidity from the air that is being cooled.
- Air conditioning systems are well known in the art and are effective means to control the temperature of a closed space. For example,
FIG. 1 depicts aconventional air conditioner 101 where room air is moved across coils filled with cold refrigerant. The refrigerant absorbs heat from the air resulting in a phase change and is then compressed to a liquid and exhaust heat out of the system, it is then expanded to reduce pressure and enters the coils again. - One of the problems commonly associated with
system 101 is its limited efficiency. For example, the room air contains water vapor that prevents the air from cooling much past 65 degrees Fahrenheit limiting the cooling of the closed space. - Accordingly, although great strides have been made in the area of air conditioners, many shortcomings remain.
- The novel features believed characteristic of the embodiments of the present application are set forth in the appended claims. However, the embodiments themselves, as well as a preferred mode of use, and further objectives and advantages thereof, will best be understood by reference to the following detailed description when read in conjunction with the accompanying drawings, wherein:
-
FIG. 1 is a schematic of a common air conditioner; -
FIG. 2 is a schematic of a glycol based dehumidifier system in accordance with a preferred embodiment of the present application; -
FIG. 3 is a cross-sectional side view of the reservoir ofFIG. 2 ; and -
FIG. 4 is a flowchart of the preferred method of use of the system ofFIG. 2 ; and -
FIG. 5 is an alternative embodiment of the system inFIG. 2 . - While the system and method of use of the present application is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and are herein described in detail. It should be understood, however, that the description herein of specific embodiments is not intended to limit the invention to the particular embodiment disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present application as defined by the appended claims.
- Illustrative embodiments of the system and method of use of the present application are provided below. It will of course be appreciated that in the development of any actual embodiment, numerous implementation-specific decisions will be made to achieve the developer's specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.
- The system and method of use in accordance with the present application overcomes one or more of the above-discussed problems commonly associated with conventional air conditioners. Specifically, the invention of the present application removes the water vapor from them room air allowing the air to cool to about 55 degrees Fahrenheit. This and other unique features of the system and method of use are discussed below and illustrated in the accompanying drawings.
- The system and method of use will be understood, both as to its structure and operation, from the accompanying drawings, taken in conjunction with the accompanying description. Several embodiments of the system are presented herein. It should be understood that various components, parts, and features of the different embodiments may be combined together and/or interchanged with one another, all of which are within the scope of the present application, even though not all variations and particular embodiments are shown in the drawings. It should also be understood that the mixing and matching of features, elements, and/or functions between various embodiments is expressly contemplated herein so that one of ordinary skill in the art would appreciate from this disclosure that the features, elements, and/or functions of one embodiment may be incorporated into another embodiment as appropriate, unless described otherwise.
- The preferred embodiment herein described is not intended to be exhaustive or to limit the invention to the precise form disclosed. It is chosen and described to explain the principles of the invention and its application and practical use to enable others skilled in the art to follow its teachings.
- Referring now to the drawings wherein like reference characters identify corresponding or similar elements throughout the several views,
FIG. 2 depicts a schematic of a glycol based dehumidifier system in accordance with a preferred embodiment of the present application. It will be appreciated thatsystem 201 overcomes one of more of the above-listed problems commonly associated with conventional air conditioners. - In the contemplated embodiment,
system 201 includes areservoir 203 filled with aglycol solution 205 havingcoils 207 passing therethrough and configured to chill theglycol solution 205 via acondenser 211. Thisglycol solution 205 is passed through the room air of anair conditioner 101 where it further cools the air and removes the water vapor therefrom. Theglycol solution 205 then returns thereservoir 203 and is cooled again. Theglycol solution 205 is moved from thereservoir 203 to theair conditioner 101 via anelectric pump 209. - It should be appreciated that one of the unique features believed characteristic of the present application is that the water vapor from the room air is removed allowing it to be further chilled an improve the efficiency of the
air conditioner 101. It will be appreciated that theglycol solution 205 does not mix with the room air and that it operates as closed loop system. - It will be understood that a reversing valve (not shown) could be used to reverse the flow of the
system 201 to run the cycle in reverse. - Referring now to
FIG. 3 a cross-sectional side view of thereservoir 203 is depicted.Reservoir 203 having abody 301 that encloses acompartment 303. It will be appreciated that volume of thecompartment 303 will be smaller or larger dependent on amount ofglycol solution 205 needed to remove the water vapor from the room air. - It will be appreciated that
system 201 will greatly improve the efficiency of conventional evaporative air conditioners that chill air by passing it through screens wetted with water. It will be understood that in areas were the air contains high amounts of water or humidity that evaporative coolers are less efficient. The preferred method of usingsystem 201 with an evaporative cooler is depicted inFIG. 4 .Method 401 including channeling the chilled glycol solution through the air of aevaporative cooler 403, allowing the glycol to chill theair 405, allowing the moisture in the air to condensate 407, using the air to cool aspace 409 and repeating the process while the evaporative cooler is inuse 411. - Referring now to
FIG. 5 an alternative embodiment of thesystem 201 is depicted.Embodiment 501 including similar features assystem 201 wherein theglycol 205 flow intubing 517 from thereservoir 203 passes through thewater 505 of anevaporative cooler 503. Wherein abody 507 encloses aspace 509 where thewater 505 is stored.Air 515 passes from afirst side 511 to asecond side 513 as the water is circulated near thefirst side 511 and allowed to evaporate. Theglycol 205 flow chills thewater 505 enabling it to chill the air and reduce the humidity thereof as it exists through thesecond side 513. - The particular embodiments disclosed above are illustrative only, as the embodiments may be modified and practiced in different but equivalent manners apparent to those skilled in the art having the benefit of the teachings herein. It is therefore evident that the particular embodiments disclosed above may be altered or modified, and all such variations are considered within the scope and spirit of the application.
