ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a heat transfer system and more particularly pertains to optimizing the heat gained and lost when air conditioning and purifying water.
2. Description of the Prior Art
The use of heat transfers systems of known designs and configurations is known in the prior art. More specifically, heat transfer systems of previously known designs and configurations previously devised and utilized for the purpose of handling heat in thermal systems through know methods and apparatuses are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.
By way of example, U.S. Pat. No. 4,939,906 to Spatz et al. relating to a gas-fired desiccant regenerator/interchanger heat exchanger. U.S. Pat. No. 5,040,375 to Von Dobeln discloses a method and devise for conditioning of a gas which passes through the treatment zone in a regenerative moisture exchanging apparatus. Lastly, U.S. Pat. No. 5,771,710 to Erickson discloses a absorption step of a continuous absorption cycle apparatus in externally cooled by an air-cooled thermosyphon having hot end air-cooled end and reservoir.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a heat transfer system that allows optimizing the heat gained and lost when air conditioning and purifying water.
In this respect, the heat transfer system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of optimizing the heat gained and lost when air conditioning and purifying water.
Therefore, it can be appreciated that there exists a continuing need for a new and improved heat transfer system which can be used for optimizing the heat gained and lost when air conditioning and purifying water. In this regard, the present invention substantially fulfills this need.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of heat transfer systems of known designs and configurations now present in the prior art, the present invention provides an improved heat transfer system. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved heat transfer system and method which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises a heat transfer system comprises an air conditioner for manipulating temperature and circulating air. The air conditioner components include an expansion valve, an evaporator, a compressor, a condenser, a closed line with a working fluid therein operatively coupling such component. The compressor increases the pressure of the working fluid thus raising the temperature of the working fluid. The condenser then releases this heat into an environment adjacent the condenser preferably into an external environment then the working fluid passes through the expansion valve, the pressure of the working fluid is then dropped which in turn lowers the temperature. The cool working fluid then passes through the evaporator where the working fluid absorbs heat from an environment adjacent to the evaporator, preferably an internal environment before entering the compressor again. The system also has a chamber having an air duct comprised of an input end for receiving fresh ambient make up air and for also receiving recycled air. An output end of the air duct moves conditioned air passed the evaporator and into the chamber and the air duct has intermediate zones between the input end and the output end. The intermediate zones include a return air zone which collects recycled air and heat. A make up air zone which collects ambient make up air. An air handler zone which comprises the air conditioner evaporator and allows the ambient make up air and recycled air to come in contact with the evaporator of the air conditioner. The last intermediate zone is an air supply zone which controls the air flow of the ambient make up air and recycled air with a fan to move the air to the output end of the air duct. Next, the system includes a distiller for purifying water through heat vaporization with an input end to receive water from a feed water source. The distiller includes outputs having a first line to pass purified water to a hot water tank, a second line to feed water to a cold water supply and a third line to feed water to a chilled water loop. Next, the distiller includes an exhaust chimney to direct the flow of excess heat and recycled air to atmosphere or for recirculation. Finally, the distiller includes a heater element to effect the water purification through distillation within the distiller. Next, the system includes a conduit with a hollow configuration adapted to carry the excess heat and recycled air from the exhaust chimney. The chimney has an input region coupled to the exhaust chimney of the distiller and an output region adapted to couple to the return air zone of the air duct when in a first mode. The output region is also adapted to route the heat and recycled air to the environment outside the chamber when in a second mode with a damper movable between the first and second mode. The conduit transfers the heat and recycled air from the distiller to the ambient make up air of the return side of the evaporator and make up air zone of the air duct and drives the moisture from the ambient make up air. Finally, the conduit is adapted to transfer the heat to outside the chamber when the air conditioner is not in use and the damper is engaged. Next, the system includes a thermosyphon having a pair of ends with a coil at each end thereof and a pair of lines connecting the coils there between forming a closed loop for a second working fluid to pass. The first heated end being located in operative association with the exhaust chimney of the distiller and the second chilled end located in operative association with the second output end of the air duct. The line having a control valve adapted to be controlled manually and by a humidostat to manipulate the degree of reheating done to the conditioned output air of the air supply zone. The excess heat of the exhaust chimney of the distiller adapted to raise the temperature of the second working fluid of the first heated end of the thermosyphon which is adapted to lower the temperature of the second working fluid at the second chilled end which in turn will absorb heat from conditioned out put air at the air supply zone. Finally, the system includes a secondary hot water tank fed by water from the distiller by a line and a secondary thermosyphon to heat the water in the secondary hot water tank.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims attached.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways.
