  • Patent number: 8871062
    Abstract: An apparatus and method are disclosed for controlling the thickness of a flowing, laminar fluid film. The film flow may be gravity-induced or the result of an alternative force. The fluid is deposited on an upper end of a flow surface where a relatively thick layer of the film forms. The film flows over a fluid dispersal region where the surface area is rapidly expanding, which results in rapid thinning of the film thickness. The fluid then flows over an active region where the surface area is designed to control the fluid film thickness. For example, in some applications, it may be desirable to maintain an approximately constant film thickness as the fluid flows over the active region of the surface. The geometry of the flow surface is used to obtain the desired control over the fluid film thickness. The flow surface is the outer surface of a solid with a closed upper end and a lower end that may be open or closed.

    Abstract: A compact evaporator including a suction baffle system is provided for use in a refrigeration system. The suction baffle system includes a suction baffle and a passageway. The suction baffle includes a plurality of walls and is adjacent to the interior wall of shell. The passageway extends below one of the walls of the suction baffle toward the lower portion of the shell and is adjacent to the interior wall of the shell. A suction tube having an inlet is attached to the evaporator shell and the inlet is adjacent to the passageway and located partially below the suction baffle. The passageway minimizes the possibility of liquid carry-over in the suction tube that feeds into the compressor.

  • Publication number: 20100175865
    Abstract: A probe mounted directly to a conduit conveying a process stream of gas to be analyzed, which can condition a continuous sample of the gas before it is analyzed by removing undesirable vapor components of the sample through interaction with a heat exchanger conduit which condenses these components into a liquid such that they precipitate under the force of gravity back into the process stream. The probe uses a Venturi device to motivate the gas through a flow cell chamber where it interacts with light shown through the chamber before ejecting the sample back into the process stream through a sample return conduit.

  • Patent number: 7481857
    Abstract: Process and reaction unit for isothermal shift conversion of a carbon monoxide containing feed gas, the process comprising the steps of introducing the feed gas in a reaction unit into reactor tubes with a fixed bed of a shift conversion catalyst in a reaction zone; contacting the feed gas with the catalyst at conditions being effective in carbon monoxide shift conversion reaction with steam reactant to hydrogen and cooling the reaction by indirect heat exchange with a cooling agent by passing the cooling agent in a falling film along shell side of the reactor tubes and removing heated cooling agent from the falling film; passing hydrogen when it is formed by the shift conversion reaction through a hydrogen selective membrane to a permeate zone; withdrawing hydrogen from the permeate zone and carbon monoxide depleted feed gas from the reaction zone.

  • Publication number: 20080149311
    Abstract: A spray type heat exchange device includes a spray unit, a first group set of heat transfer tubes, at least a distributing unit and a second group set of heat transfer tubes. The distributing unit redistributes the remaining liquid refrigerant that is sprayed out from the spray unit and flowed through the first group set of heat transfer tubes, and the remaining liquid refrigerant is dropped downwardly to the second group set of heat transfer tubes. By this disclosed method, the inner space of the heat exchange device could be fully utilized to configure and accommodate more heat transfer tubes therein.

  • Publication number: 20080121379
    Abstract: The present invention comprises an apparatus and method for evaporating a liquid to produce a product liquid and a vapor. Liquid is evaporated under the influence of a heat transfer medium in a heat exchanger comprised of a bank of tube plates formed from corrugated sheets. Vapor produced is separated from product liquid by a vapor collector which causes vapor to flow upward and into the collector from a downward-flowing product liquid and vapor stream. Backsplash entrainment into the vapor collector is prevented by an anti-backsplash device disposed between the vapor collector and a reservoir into which product liquid flows.

  • Publication number: 20080047698
    Abstract: This invention teaches how to reduce the copper content of a commercially available, all-copper, double-wall-vented, coil & tube Gravity Film Heat Exchangers (“GFX”) developed for the GFX™ system of U.S. Pat. No. 4,619,311. For example, a GFX+™ equivalent of a residential Model G3-60 GFX can be made using 71% less copper. Such significant copper-savings, with comparable heat transfer coefficient (“U”), effectiveness and coil pressure drop, is achieved by improvements in innovations disclosed in Provisional Patent Application 60/709,889 (Filing date: Aug. 22, 2005). Unlike conventional, single and multi-coil GFX's currently produced by several manufacturers, the present invention enables the use of a variety of metal and/or plastic components to achieve either single or vented-double-wall construction and lower manufacturing costs. In fact, higher U-values can be achieved by increasing the potable-water pressure drop of a GFX+ equivalent of any coil & tube GFX.

  • Patent number: 7222659
    Abstract: A heat management system include including application of phase change materials (PCM). A heat or cold storage multistage tower has a housing with a multistage system of flat rigid container. A significant fraction of internal space of each container is filled with PCM; these containers are fabricated from ceramics, glass, glass ceramics or sulfur concrete. Another version of the heat or cold storage tower is based on application of multi-channel blocks from ceramics, glass, glass ceramics or sulfur concrete; the parallel internal vertical channels of the blocks are open and sealed at their bottoms alternatively, and the channels with the sealed bottoms are filled partially with PCM. The tower achieves effective heat transfer between a heat transfer fluid (HTF) and PCM in the processes of charging and discharging of the containers with heat or cold.

  • Patent number: 6948558
    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: 6868695
    Abstract: A falling film evaporator includes a flow distributor for uniformly distributing a two-phase refrigerant mixture across a tube bundle. The flow distributor includes a stack of at least three perforated plates each of which are separated by nearly full-width, full-length gaps or chambers. The flow distributor may also include a suction baffle and/or a distributor baffle. The distributor baffle extends downward to provide a hairpin turn past which refrigerant travels before exiting the evaporator. This directional change helps separate liquid from a primarily gaseous refrigerant stream. The suction baffle has various size openings to ensure that the flow rate of refrigerant through the hairpin turn is generally uniform and is maintained low enough to ensure liquid disentrainment over and along the length of the tube bundle within the evaporator.
