  • Patent number: 10288355
    Abstract: Heat exchanger assemblies and methods are provided for cooling the interior of an enclosure (e.g., electrical cabinets, computer server racks, chemical chambers, and animal cages). Heat is transferred via thermal conduction from a first plurality of surfaces positioned inside the enclosure to a second plurality of surfaces positioned outside the enclosure. The first and second plurality of surfaces remain in thermal contact with one another during use. Heat is dissipated from the second plurality of surfaces to the ambient air outside the isolated environment without the ambient outside air mixing together with the air inside the enclosure. This, in turn, inexpensively removes heat from the air inside the enclosure and prevents contaminants from entering the enclosure.

    Abstract: A cryogenic refrigerator of a cryopump generates cryogenic cooling in an expansion volume by reciprocally moving a displacer in a cylinder. A cryopanel and a cup-shaped shield are received in a vacuum chamber of the cryopump and are cooled by the cryogenic cooling. The shield protects the cryopanel from radiant heat of the vacuum chamber. A louver is provided at an upper opening of the shield. A hole is formed at a bottom or side of the cup-shaped shield defining a storage part. Molecules in the vacuum chamber are solidified at or absorbed by the cryopanel and the shield. During regeneration, temperature of the cryopanel and the shield is increased. Water molecules desorbed and liquefied from the louver, the shield or the cryopanel are accumulated during regeneration at the storage part that has enough volume to store the water molecules.

  • Publication number: 20080302114
    Abstract: A system for storing articles can have at least two operating modes. In the first mode, gases are evacuated from the system whereby the articles are stored at a pressure less than the pressure at the exterior of the system. In the second mode, gases are evacuated while the system is open to the admittance of gases from the exterior of the system whereby the articles are ventilated by the admitted gases. The system also can have a third operating mode wherein both the first and second modes are rendered inoperative. The storage system can function so that when the articles are stored in the first mode, gases are intermittently removed from the system whereby the pressure at which the articles are stored is maintained at less than the pressure at the exterior of the system. The storage system can be located in a refrigeration appliance such as a household refrigerator.

  • Patent number: 7124580
    Abstract: A pre-condenser is provided for condensation of water at sub-zero degree Celsius temperatures. A brine solution is cooled below 0 degrees Celsius and delivered to the pre-condenser. The brine solution contacts the vapors and gases from a scrubber, thereby condensing the vapors without allowing ice formation. A vacuum system connected to the pre-condenser removes the remaining gases from a top portion of the pre-condenser while the brine solution and condensed vapors are removed and recycled through a bottom portion of the pre-condenser.

  • Patent number: 6902755
    Abstract: A method and apparatus for rapidly chilling liquid or slurried food products through a two-stage sequence of jacket cooling followed by vacuum chilling. Slurry and liquid food products heated in a batch are chilled by first employing a chilled liquid flowing through a double walled jacket (22) surrounding the vessel chamber (17). When the food product reaches a temperature at which jacket cooling becomes inefficient, this is followed by pulling a vacuum in the space above the product to vacuum cool the product to the desired chilled temperature.

  • Publication number: 20040154330
    Abstract: A horizontal type compressor comprising: a differential pressure plate for dividing an inside of a casing into a high pressure chamber and a lower pressure chamber and thus maintaining an oil level of the high pressure chamber to be higher than that of the lower pressure chamber; and a lubricating unit for supplying oil stored in the high pressure chamber to each sliding part in the compressor and making the oil which finished a lubricating operation return to the high pressure chamber from the lower pressure chamber. The compressor smoothly supplies refrigerant oil and minimizes an amount of the refrigerant oil discharged outside the compressor, thereby prolonging a life of the compressor and increasing a reliability of the compressor. Also, the differential pressure plate and the muffler are integrally formed, thereby reducing a fabricating cost and reducing an assembling process.

  • Patent number: 6755043
    Abstract: In cooling plants which work with water as both primary and secondary coolant, it is customary for use to be made of both an evaporator and a condenser which must be supplied wi5th water in the form of e.g. a spray for achieving an effective heat exchange, and out of regard for the effectiveness it is necessary for a continuous deaeration of the water to be carried out, which is effected by the sucking of air direct from the condenser, possibly supplemented with an external NCG condenser or by leading the supply water through a pre-deaerator under vacuum. With the invention it has been found possible to configure both the evaporator and the condenser with associated deaeration/pre-deaeration units in a fully integrated manner, namely by mounting a pair of sieve plates in a vacuum container for the dividing of the container into an upper supply- and distribution chamber, a centremost pre-deaeration chamber (one or more), and a bottom chamber in the form of an evaporator- and a condenser chamber respectively.
