    Abstract: A cooling tower with a hot water distribution system includes a distribution lateral disposed above a hot water basin. The distribution lateral discharges fluid into the hot water basin, which in turn, releases the fluid through a plurality of orifices. As the fluid is released, it falls on heat-exchanging fill material that assists in increasing the cooling rate of the fluid. The distribution lateral is configured structurally to discharge the fluid through a plurality of outlets at one or more angles (as compared to the horizontal) into the hot water basins. In one embodiment, the outlets are arranged into one or more rows that extend along a substantial length of the distribution lateral. Discharging the fluid in this manner enhances and promotes a more even fluid flow within the hot water basin, which results in a more even fluid flow over and onto the fill material, thereby increasing thermal efficiency.

The analysis system has a device for dividing a gas flow stream into two portions and for submerging a membrane humidifier tube, containing one of the gas flows, in a water bath in which the gas passing through that tube is moisturized to a desired degree. The two gas flows are subsequently reunited at a controlled temperature to provide for combined moisturized gas at a desired temperature and humidity. The gas is then sprayed onto the sample and an excess moisturized gas vented from the chamber to maintain a moisturize gas sample without condensation of water on or near the sample. This system and a method for its use allow measurements of samples to be made as a function of humidity and temperature over wide ranges of these parameters under highly stable conditions in a straightforward manner which are not susceptible to malfunction and which can be produced and operated at low cost.

  • Patent number: 6557551
    Abstract: A humidification unit adapted to be disposed in a patient circuit for humidifying the flow of breathing gas delivered to the patient via the patient circuit by an artificial ventilator system. The humidification unit includes an exothermic member having an outer surface and a plurality of hollow fibers disposed on the outer surface of the exothermic member. Each hollow fiber is defined by a peripheral wall having minute openings large enough to allow a gas to pass therethrough yet small enough to prevent a liquid from passing therethrough. Liquid delivered to the hollow fibers is heated by the exothermic member and the gas vapor resulting from the heating passes through the hollow fiber walls and humidifies the flow of breathing gas delivered to the patient.

  • Patent number: 6554261
    Abstract: A humidifier includes a housing that accommodates bundles of a large number of water permeable hollow fiber membranes arranged along the longitudinal direction of the housing. Two different gasses having different moisture contents pass through outside and inside of the bundle of the hollow fiber membranes separately to exchange their moistures through the hollow fiber membranes resulting in the dry gas of lesser moisture content being humidified. A heating or temperature adjuster is provided to maintain the temperature of the exhaust gas introduced to the humidifier or the bundles of hollow fiber membranes substantially at a temperature of a fuel cell in operation.

  • Publication number: 20030047821
    Abstract: The invention relates to a packing for heat- and material-exchange columns, with a number of approximately perpendicularly arranged corrugated plates (or strips), with the side surfaces thereof lying adjacent to each other. The ribs of the above lie very close to each other and run from top to bottom, in the approximate form of an arc, whereby the ribs of two adjacent plates cross each other and the ribs in the upper region of a plate are straight and inclined to the upper, in particular, horizontal plate edge and, in the lower region of the plate, run bent in the form of an arc.

  • Patent number: 6145818
    Abstract: A heat exchanger includes a tube register through which a liquid to be cooled or heated is conveyed. The heat exchanger provides for contacting an outside surface of the tube register with a spray of water flowing in the same direction on the outside of the tube register as the fluid flows within the tube register, and a stream of air flowing in the opposite direction on the outside of the tube register as the fluid flows within the tube register. The tube register includes capillary tubes which extend generally parallel to each other and which are bent back about one or several lines extending transverse to the directions of air and water flow past the tube register to form layers of the tube register one upon another. The spaces between the capillary tubes are at least partly filled with foamed material.

  • Patent number: 6095505
    Abstract: An improved breathing gas humidifier including an evaporation module which has a contact chamber and a flash-resistant heat exchanger, a wicking layer on the heat exchanger, a liquid water flow controller, an electric resistance heater, and a breathing gas temperature controller. The contact chamber is defined by a rigid housing and in part by a flash-resistant heat exchanger. The rigid housing has a gas inlet for connection to a breathing gas source such as a ventilator, a water inlet for connection to a liquid water source by a liquid water flow passageway, and a breathing gas outlet connected to an inhalation passageway. The wicking layer is positioned in the contact chamber to receive and distribute liquid water. The breathing gas temperature controller is operably connected to the flow controller, the heater, and a temperature sensor in the breathing gas outlet.

  • Patent number: 6054049
    Abstract: To improve the affinity between a gas and a liquid, the liquid is passed through an enclosure where it contacts a portion of the magnets of a magnetic field generating device and passes through the magnetic field created by the magnets while a gas is in contact with the other portion of the magnets. A liquid level control device maintains and controls the liquid level so that the magnets simultaneously extend about equally into the gas and liquid with both contacting the magnets and being within the magnetic field created by the magnets. The gas in the enclosure increases the effectiveness that the magnetic field and magnets have on the liquid. The gas used in the enclosure can optionally subsequently be mixed with the liquid or another gas can be mixed with the liquid. Additional gases and liquids can be mixed together. The device and process associated with it can be used on different liquids and different gasses, including fuel mixed with air in a combustion process.

  • Patent number: 5946932
    Abstract: A multistage condensing structure using a liquid dispensing means to transfer droplets of evaporative cooling liquid onto an air-cooled condenser, taking advantage of the conventional air-cooled condensing method and the evaporation method using a liquid coolant. To further increase the efficiency of the air conditioner, two or more condensing units can be arranged in tandem along the blowing direction of a common air blower. With two or more condensing units arranged in tandem, the contacting area between the evaporation surfaces and the air flow can be enlarged to increase the evaporation efficiency without significantly increasing the size of the air conditioner. The multistage condensing structure, with its continuous heat-exchange along the flow of the refrigerant in the coiled pipe, causes an increase in the subcooling condition in the refrigerant. This condensing structure can, therefore, achieve a much higher E.E.R. than the known method of air cooling.
