  • Patent number: 8397529
    Abstract: An air conditioning system including an evaporator having a manifold and a plurality of tubes extending downward in a vertical direction from the manifold. The evaporator defines at least one PCM tank engaging the manifold for storing a phase change material. When operating in a first operating mode, heat is transferred from the phase change material to the refrigerant to freeze and cool the phase change material. When operating in a second operating mode, heat is transferred from the refrigerant to the frozen phase change material to condense the refrigerant. The condensed refrigerant falls downwardly through the tubes and receives heat from a flow of air to cool the air and evaporate the refrigerant. The evaporated refrigerant rises upwardly back to the low pressure of the cold manifold.

  • Publication number: 20100304233
    Abstract: 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.

  • Patent number: 7770632
    Abstract: The invention provides for an orientation insensitive heat exchanger assembly for cooling an electronic device comprising a hermetically sealed housing defining a boiling chamber and two condensing chambers. A partition is disposed in the boiling chamber and defines two sets of alternating channels extending in overlapping relationship to one another and with one set of alternating channels open to one of the condensing chambers and the other set of alternating channels open to the other condensing chamber for sealing the condensing chambers from one another. Coolant is maintained in each of the condensing chambers. In operation, if the thermosiphon is tilted with one side lower than the other, the channels open to the lower side are empty of coolant into the lower condensing chamber while the channels open to the opposite upper side hold the coolant over the entire boiling chamber aligning with an electronic device to continue cooling.

  • Publication number: 20100126343
    Abstract: An electrically enhanced air filter apparatus for filtering particles from moving air is described. The apparatus includes a filter arranged so particles approach the filter a filter speed and pass through an ionizer at an ionizer speed, and is configured so the filter speed is less than the ionizer speed. The ionizer is arranged to guide the moving air in an ionizer airflow direction and generates an ionizing electric field having ionizer field direction substantially perpendicular to the ionizer airflow direction.

  • Publication number: 20100077783
    Abstract: 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.

  • Publication number: 20100058778
    Abstract: 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.

  • Patent number: 7658084
    Abstract: A refrigeration assembly includes a pair of refrigerated chambers defined within a working chamber. The refrigerated chambers include channel walls extending parallel to one another and spaced apart, and first and second panels extending channel walls to define a working channel for separating the working chamber into sub-chambers. Apertures defined in the panels allow airflow from the sub-chambers into the working channel, and a supply of water wets the panels and a first section of the refrigerated chambers. Air enters the sub-chambers and flows over the first sections of the refrigerated chambers for direct evaporative cooling. A portion of the air bleeds through the apertures and evaporates water from the panels prior to flowing over the second sections of the refrigerated chambers for indirect evaporative cooling.

  • Patent number: 7654307
    Abstract: An automotive air conditioning system is disclosed comprising an evaporative cooler in series with the conventional vapor compression system. The evaporative cooler comprises an array of dry channels and a contiguous array of wet channels. The primary air stream to be conditioned by the evaporator of the conventional air conditioning system is preconditioned by the evaporative cooler by lowering its dry bulb temperature without changing its absolute humidity. An evaporator core is supported downstream of the evaporative cooler for receiving the primary air from the dry channels and thereby produces liquid condensate. The system is distinguished by conducting the liquid condensate from the evaporator core to the wicking tank for use in the wet channels of the evaporative cooler.

  • Publication number: 20090211293
    Abstract: An air conditioning system for circulating a refrigerant includes a condenser having a vapor inlet for condensing the refrigerant into a high-pressure liquid having a first predetermined temperature. A heat exchanger including an exhaust channel directs air therethrough. The heat exchanger further includes a refrigerant inlet in fluid communication with a refrigerant outlet for receiving a high-pressure liquid and for delivering the high-pressure liquid therethrough. Furthermore, a heat mass exchanger outputs wet working air having a second predetermined temperature. The heat exchanger is in fluid communication with the heat mass exchanger for receiving the working air having a temperature less than the high-pressure liquid. The working air flows through the exhaust channel and over the high-pressure liquid to transfer heat from the high-pressure liquid to the working air for reducing the temperature of the high-pressure liquid.
