20100000247 | Solar-assisted climate control system - A method for providing climate control is disclosed herein. The method includes the step of circulating liquid desiccant in a first fluid circuit. The method also includes the step of disposing a dehumidifier along the first fluid circuit. The method also includes the step of disposing a regenerator along the first fluid circuit downstream of the dehumidifier. The method also includes the step of harnessing solar energy with at least one solar collector. The method also includes the step of circulating coolant in a second fluid circuit. The at least one solar collector and the regenerator are both disposed along the second fluid circuit whereby the coolant is heated during passage adjacent to the at least one solar collector and transfers thermal energy to the liquid desiccant during passage through the regenerator. The first and second fluid circuits are in parallel in the regenerator. | 01-07-2010 |
20100001086 | Comfort heating system for motor vehicle - A method for heating ambient air for a passenger compartment of a motor vehicle is disclosed herein. The method includes the step of positioning a first heat exchanger proximate to a passenger compartment of a vehicle. The method also includes the step of passing ambient air for the passenger compartment through a first heat exchanger. The method also includes the step of concurrently directing distinct flows of engine coolant and steam to the first heat exchanger to heat the ambient air. | 01-07-2010 |
20100058778 | Thermoelectrically powered indirect evaporative cooling system with desiccant dehumidification - Disclosed is a system for cooling using indirect evaporative cooling, dehumidification using desiccant, and a thermoelectrically powered heat exchanger. The thermoelectric heat exchanger pulls heat from the working air exiting the indirect evaporative cooler and injects that heat energy into ambient air that is then forced through a portion of the rotating desiccant wheel to regenerate the desiccant by removing water molecules from the desiccant material. Liquid water that is condensed by cooling the working air with the thermoelectric heat exchanger is saved and provided to the indirect evaporative cooler for use to cool via evaporation. | 03-11-2010 |
20100058794 | Low profile evaporative cooler - An evaporative cooler assembly includes a plurality of tubes extending from a refrigerant tank in a spaced relationship to one another with each tube defining a wet air passage. Each pair of adjacent tubes defines a dry air passage extending transversely to the tubes. Each tube includes a plurality of orifices each in fluid communication with the corresponding wet air passage and the adjacent dry air passage. A pair of air ducts are disposed on the refrigerant tank with the tubes being disposed between the air ducts and the air ducts being in fluid communication with the dry air passages whereby a dry air stream flows sequentially through a portion of the dry air passages and into one of the air ducts and through another portion of the dry air passages and into the other air duct until the dry air stream flows out of a dry air outlet as conditioned air. | 03-11-2010 |
20100060005 | Power generation system using low grade solar energy - Disclosed is a system providing practical power generation from heat energy input from a low grade source, such as solar energy. In a modified Rankine cycle, increased energy is extracted via the turbine by letting the working fluid drop to a lower pressure. Phase change of the low pressure working fluid is accomplished using enhanced condensation. Condensation is enhanced by use of an evaporative cooler. To enable continued operation when solar exposure is attenuated, a supplemental heater is included to heat the working fluid. | 03-11-2010 |
20100077783 | Solid oxide fuel cell assisted air conditioning system - A housing rotatably supports a desiccant wheel, Ambient air passes through one part of the housing and hot exhaust air passes through the other part. As the wheel rotates, it absorbs moisture from the ambient air in part of the housing and desorbs moisture into the exhaust air in the other part. A fuel cell system supplies the hot exhaust air directly to the desiccant wheel, The dry ambient air is directed to an evaporative cooler and divided between dry channels and wet channels, The air passing through the dry channels cools to be directed to a conditioned space. The air passing through the wet channels evaporates water in the channels facilitating heat transfer and adding moisture to that air. The air from the wet channels is optionally added back into the air from the dry channels to provide appropriate humidity. | 04-01-2010 |
20100083501 | Continuous manufacturing process for metal-plastic hybrid heat exchanger - The invention is a method for producing a heat exchanger assembly including the steps of extruding a plastic and an adhesive from a co-extrusion die into a plurality of tubes spaced from each other with each tube having an adhesive disposed on its exterior surface. A plurality of corrugated air fins are serially fed into the co-extrusion die and spaced from each other by a predetermined space and ejected between adjacent tubes with the corrugations extending transversely between the tubes. The adhesive is then cured to secure the tubes to the air fins. The method proceeds by cutting the tubes at each predetermined space with a guillotine shear to produce a plurality of unified heat exchanger cores. The ends of the tubes of each core are inserted into tube slots in manifolds, and the tubes and manifolds are adhesively secured together to define a heat exchanger assembly. | 04-08-2010 |
20100146953 | EXHAUST GAS STEAM GENERATION SYSTEM - A cylindrical stainless steel housing includes an exhaust inlet collar and exhaust outlet collar allowing exhaust gas to travel therethrough at a mean flow velocity in accordance with a velocity formula. A plurality of stainless steel tubes extend through the housing from a steam inlet manifold to a steam outlet manifold. A number and size of the tubes is determined by formulas and dependent on an Euler number, a Reynolds number, a number of transfer units, a Prandtl number, a porosity factor and a system efficiency. The tubes may comprise an S-shape or a U-shape. The tube walls have a thickness determined according to wall thickness formulas and the walls include a plurality of cavities on an interior surface of each tube wall. The cavities may comprise a conical or semi-spherical shape and have a diameter determined according to formulas. | 06-17-2010 |
20100304233 | FUEL CELL ASSEMBLY - A fuel cell assembly for using hydrogen gas and oxygen to produce electrical energy. The cathode of the fuel cell produces water vapor to define a flow of moist air including water vapor. A dehumidifier receives the flow of moist air including water vapor to produce purified liquid water and a flow of dehumidified air. The dehumidifier has an air inlet having a first cross-sectional area and an air outlet having a larger second cross-sectional area. The diffuser cavity of the dehumidifier progressively increases in size from the air inlet to the air outlet for depressurizing and cooling the flow of moist air including water vapor below the dew point of the moist air including water vapor to condense the water vapor on the housing of the dehumidifier. | 12-02-2010 |
