  • Publication number: 20150082817
    Abstract: A low temperature cooling and dehumidification system uses a reverse airflow arrangement to defrost a frosted cooling coil while not interrupting operation. Automatic air dampers are used to reverse the airflow at the proper time to initiate defrost of that section of frosted cooling coil. This system is useful for low temperature cooling and dehumidification in situations where the inlet air is above freezing, however exiting air below freezing can be supplied if desired. It is advantageous for operation if the coolant flow and temperature internal to the cooling coil are regulated to create the conditions for frost formation to begin closer to the air leaving side of the active cooling coil. The dehumidified generated condensate can be collected and used as grey water and/or potable water.

    Abstract: An appliance such as a refrigerator receives a demand response signal indicating a peak demand period and operates the refrigerator in an energy savings mode by disabling an anti-sweat heater. A sensor on an external surface of the refrigerator enables the anti-sweat heater during the peak demand period if moisture is detected by the sensor. A preselected location can be defined where incipient moisture would form such as reducing the amount of insulation in this location. By forming a depression in the location and using an impedance-type sensor, moisture can be easily detected. The sensor signal is sent to the controller which then activates the anti-sweat heater to remove the moisture.

  • Publication number: 20110179808
    Abstract: A cryogenic system comprises: a liquid helium vessel containing liquid helium (LHe) in which are immersed superconducting magnet windings (20); a helium condenser (30); a neck (32) providing fluid communication between the liquid helium vessel and the helium condenser; a heater (42) disposed outside of and not surrounding the neck; and a thermally conductive passive deicing member (50) disposed in the neck, the thermally conductive passive deicing member thermally coupled with the heater to conduct heat from the heater into the neck. A deicing method for deicing a neck (32) of a liquid helium vessel of a superconducting magnet system comprises generating heat at a location (30, 42) outside of the neck and conducting an amount of the generated heat effective for deicing the neck from outside of the neck through an opening of the neck and into the neck to deice the neck.

  • Publication number: 20110138834
    Abstract: A refrigerating apparatus is provided with a cooling unit whose height is greater than width when installed; and a defrosting device for defrosting frost formed on the cooling unit by heat, the defrosting device being in a straight pipe form, wherein the defrosting device is provided in a vertical direction on a side of the cooling unit. By providing the defrosting device in a straight pipe form in the vertical direction on the side of the cooling unit that is long in a longitudinal direction, it is possible to increase the length of the defrosting device and to lower a surface temperature of the defrosting device. Further, as the defrosting device is long, an amount of heat generation is large and defrosting efficiency is high. Moreover, it is possible to manufacture the defrosting device at a low cost as the defrosting device is in a straight pipe form.

  • Publication number: 20110138822
    Abstract: An energy supply system for operating at least one air conditioning system of an aircraft, comprises at least one air line network and at least one electric line network. The air line network is connected to the air conditioning system and at least one bleed air connection for routing bleed air to the air conditioning system. The electric line network is connected to the air conditioning system and at least one electrical energy source for routing electrical energy to the air conditioning system. The air conditioning system has an electrically operable cooling device. By means of the energy supply system according to the invention the energy withdrawn from the power units is better adapted to the energy necessary for operating the air conditioning system and other systems—such as, for example, wing de-icing—and therefore reduces the excess fuel consumption of the aircraft.

  • Publication number: 20110094245
    Abstract: Disclosed is a defrosting system and a defrosting method of a refrigerator, the system including an evaporator configured to reduce an ambient temperature by heat exchange through movement of refrigerant, a frost monitoring camera by photographing a state of frost adhered to the evaporator, a controller configured to grasp changes of an image captured by the frost monitoring camera to determine a defrosting start time, and a heat-generating unit configured to emit heat in response to a signal applied from the controller to remove the frost, whereby an unnecessary operation of a heat-generating unit is prevented by appropriately coping with an environment that flexibly changes according to an inner situation of a refrigerator and by accurately determining, by the controller, a start time and a completion time of defrosting operation for removing frost adhered to the refrigerator.
