  • Publication number: 20150308711
    Abstract: A hot water heater or similar heating device includes equipment for pre-cooling hot flue gas while preheating water for the water heater. It further includes a heat and mass exchanger for transferring heat and water from the pre-cooled flue gas to combustion air for the hot water heater. The pre-cooler may comprise a separate device or may be incorporated as part of a condensing water heater. The heat and mass exchanger may use membranes having condensing sides and evaporating sides, which allow water to pass from the condensing sides to the evaporating sides. It may further comprise troughs for wetting the membranes.

  • Patent number: 8613839
    Abstract: Apparatus for distilling a fluid such as water includes a vessel and heat transfer plates within the vessel structures to form at least one each cooling channel, evaporative channel, and condensing channel. Air enters the vessel and passes through the cooling channel, where it is cooled due to evaporation taking place in an adjacent evaporative channel. In the evaporative channel, input fluid is supplied to the walls of the heat transfer plates facing into the evaporative channel and evaporation forms vapor. The vapor is condensed in a condensing channel. In some versions of the apparatus, an evaporation channel forms a vacuum chamber and a condensing channel forms a compression chamber.

  • Publication number: 20100018234
    Abstract: Heat exchanger plates for indirect evaporative coolers, of the type having a dry side having low permeability to an evaporative liquid and formed to allow a product fluid to flow over a heat transfer area of its surface, a wet side designed to have its surface wet by an evaporative liquid, and formed to allow a working gas to flow over its surface to evaporate the evaporative liquid, are formed such that the wet side comprises a hydrophobic fiber sheet and the dry side comprises a non-permeable sealing layer on the sheet. Heat seal strips are formed at the inlet and outlet of the plates and air flow perforations are formed through the plates.

  • Patent number: 7197887
    Abstract: An improved method and apparatus for indirect evaporative cooling of a fluid stream to substantially its dew point temperature. Plate heat exchanger has perforations 11 and channels 3, 4 and 5 for gas or a low temperature for liquids on a dry side and wet side. Fluid streams 1 flow across the dry side 9, transferring heat to the plate. Gas stream 2 flows across the dry side and through perforations to channels 5 on wet side 10, which it then cools by evaporative cooling as well as conductive and radiative transfer of heat from plate. A wicking material provides wetting of wet side. In other embodiments, a desiccant wheel may be used to dehumidify the gas, air streams may be recirculated, feeder wicks 13 and a pump may be used to bring water from a water reservoir, and fans may be used to either force or induce a draft. The wicking material may be cellulose, organic fibers, organic based fibers, polyester, polypropylene, carbon-based fibers, silicon based fibers, fiberglass, or combinations of them.

  • Publication number: 20050218535
    Abstract: The present invention relates to methods for indirect evaporative air-cooling with the use of plates, heat exchangers and feeder wicks—of the indirect evaporative type. Several components for an indirect evaporative heat exchanger described as follows: A plate for an indirect evaporative heat exchanger where the plate is made of laminate material having one sheet of wicking material for wet zone(s) and the other of a water proof plastic material for the dry zone(s). An evaporative heat exchanger is created by assembling the plates forming spacing for wet channels, (they are created by the wet zone of the plates,) and dry channels, (they are created by the dry zone of the plates,) with channel guides or corrugated plates. The spacing between the plates is defined to reduce pressure drop for increased airflow. A feeder wick system creates the wetting of the wet channels without excess water.

  • Publication number: 20050210907
    Abstract: An indirect evaporative cooler includes a number of heat transfer plates. Each plate has a wet side and a dry side, and the dry sides of adjacent plates face each other. The plate dry sides have low permeability to an evaporative liquid. Input air flows over the dry sides from an input end to an output end. Part of the input air becomes product air and exits at the output end. The rest of the input air passes through perforations in the plates to the other side of the plates to become working air. The other side of each plate is a wet side, which is wet by an evaporative liquid. Working gas flows over the wet side, evaporating the evaporative liquid and cooling the evaporative liquid, the plate, and finally the product gas by heat transfer. The perforations are formed both toward the input end of the plate and toward the output end of the plate.

  • Publication number: 20050056029
    Abstract: A duplex exchanger includes first and second heat exchangers each including a main flow channel and a cooperating counterheat channel. The first counterheat channel is joined to the first main flow channel for receiving a cooled primary stream therefrom. The second counterheat channel is also joined to the first main channel splitting the primary stream therefrom. An evaporative coolant is injected into the first counterheat channel, and an evaporative saturant is injected into the second counterheat channel. Heat from the initially hot primary stream in the first exchanger evaporates the coolant in the first counterheat channel for self-cooling the primary stream in the first main channel. Heat from a hot secondary stream channeled through the second main channel evaporates the saturant in the second counterheat channel for adding mass to the primary stream channeled therethrough.

  • Patent number: 6854278
    Abstract: The operating efficiency of indirect evaporative cooling processes and indirect evaporative cooling apparatus employing a dry side channel and a wet side channel separated by a heat exchange plate are improved by placement of holes in the heat exchange plate. Further improvements are obtained when the flow direction in the wet side channel is cross-current to the flow direction in the dry side channel. Placement of desiccant materials in the dry side channel also serve to improve the operating efficiencies of these processes and apparatus.

  • Patent number: 6779351
    Abstract: A fuel cell using fuel and oxidant resulting in the production of water and heat in addition to electrical power. The fuel cell employs an evaporative cooler and has methods to adjust the moisture and temperature for the fuel and oxidant flows to improve the fuel cell efficiency. The water produced by the fuel cell is used to provide the water for wet channels of the evaporative cooler. The evaporative cooler has separate product channels and dry working channels that are cooled by heat transfer across a heat exchanger plate. The heat exchanger plate forms part of each wet working channel on the wet side of the heat exchanger plate and part of the product channel and the dry working channel on the dry side. The fuel passes first through the dry working channel then the wet working channel becoming humidified by the evaporation therein and cooling the heat exchanger plate before going to the anode of the fuel cell.

  • Patent number: 6776001
    Abstract: The present invention relates to a method and an apparatus for providing enhanced indirect evaporative cooling of air, water, fuel, or other fluids while controlling the humidity. The design makes cooling down to the dew point possible without energy input other than the energy to produce the fluid flow needed. The design makes use of stacked composite plates (7) with channels (1, 2) for fluid flow between adjacent plates. On opposing surface areas of these plates, there are wet areas (4) or dry areas (3). The wet areas (4) provide cooling by conventional evaporation which is in turn used to cool the fluids in contact with the dry areas (3). The benefit is controlled heat transfer, which allows selected cooling of fluid flow such that the temperature as low as dew point are reachable.
