  • Patent number: 9458030
    Abstract: Desalination and rinsing methods and systems are provided, which use a liquid column to efficiently perform freeze desalination and enable recyclable washing of produced minerals or combustible material. The liquid column comprises alternating layers of water immiscible liquids and water solutions which form a vertical density gradient (discrete or continuous) and exhibit a lower freezing zone from which ice floats to an upper melting zone. Cooling of introduced upwards flowing salt solutions is carried out by a countering downwards flow of cold water immiscible liquid. The process is cyclical, involves few if any mechanical moving parts and is easily controllable and adaptable to varying desalination circumstances. Rinsing of minerals or combustible material may be integrated in the heat and matter flows of the desalination system to allow effective rinsing, desalination and recycling of the used water.

    Abstract: An apparatus and a method for driving an icemaker for making ice cubes in a refrigerator. An ice-full state is sensed in such a way as to rotate an ejector and a cam gear in a reverse direction (opposite to an ice-ejecting direction), thereby preventing interference with the ice cubes present in the icemaker and thus enabling the ice-full state to be accurately sensed. A first torsion spring is mounted to an intermediate gear with a small rotation angle ratio to allow only a minimum amount of torque to be transferred to other components such as an ice-detecting lever, thereby increasing the durability of the components and providing a precise rotation force. The axial center of rotation of a second torsion spring is defined at a position that faces the other end (the revolving end) of the ice-detecting lever, to allow a minimum moment to be substantially constantly applied.

In an ice making cycle, a vacuum system evacuates air from the cavities, thereby depressurizing the cavities. Then, a liquid delivery system delivers liquid to the depressurized cavities, whereby an initial portion of the liquid bubbles up within the respective cavities. Overall, a cooler fluid is established at the beginning of an ice making cycle, thus accelerating the rate at which ice cubes are formed within the fast ice making device. Once ice cubes have been formed within the cavities, a heat transfer system is utilized to heat the cavities, thereby slightly melting the ice cubes and aiding in the expulsion of ice cubes from the cavities.

An ice making unit and bag making and filling station are mounted in the housing. Ice is transported from the ice making station into partially formed bags at the bag making and filling station, and a bag is sealed and separated when a sufficient amount of ice is supplied to the bag. The bag making and filling station communicates with the passageway into a storage compartment in the freezer, whereby separated bags of ice fall into the storage compartment on completion.

  • Patent number: 8783046
    Abstract: An ice display device includes a chill tube and a piston that slides within the chill tube providing a fluidtight seal against the interior. The tube is filled with water and cooled to form an ice column. A shutter may selectively close the upper end of the chill tube with a fluidtight seal while the ice column is formed. The tube is warmed and the piston is lifted to an upper end of the tube to display the ice column. A plurality of water nozzles may selectively discharge streams of high pressure water inwardly to sculpt the ice column. An armature may extend upwardly from the piston to support and cool an interior of the ice column. The tube and armature may be cooled and warmed by a thermal transfer fluid. A device may be provided to induce turbulence in the thermal transfer fluid.

    Abstract: A refrigerator appliance and a method for operating the same are provided. The refrigerator appliance includes an ice maker for producing ice. The ice maker is deactivated for a predetermined period of time after the ice maker has been filled with liquid water. After the predetermined period of time has elapsed, the ice maker can harvest ice if a demand side management (DSM) status is off-peak, or the ice maker can remain deactivated if the DSM status is on-peak. By operating in such a manner, operating costs of the refrigerator appliance can be reduced.

  • Patent number: 8769973
    Abstract: A refrigeration system for a frozen product dispenser is controlled to have a variable cooling capacity that is determined by variable cooling load demands of the dispenser. This is accomplished, in part, by providing the refrigeration system with a variable speed compressor and one or more adjustable expansion valves for metering refrigerant to associated evaporators that are heat exchange coupled to associated freeze barrels of the dispenser, and by controlling the metering setting of the expansion valves and the speed of operation of the compressor in accordance with the cooling load demands of the dispenser. The arrangement provides for efficient operation of the refrigeration system from an energy standpoint and for a reduction in on/off cycling of the system.

  • Patent number: 8763420
    Abstract: The present invention concerns a freezer segment for a freezer of the type used for casting confectionery in molds which are cooled for freezing and subsequently supplied with heat for a short period, whereafter stripping occurs. Cooling of the molds is effected by using direct evaporation of CO2. The advantage of such a freezer segment is that there is no use for both a primary and a secondary cooling circuit. Another advantage in using a system according to the invention is that working with temperatures down to about minus 50° C. is enabled, compared to about minus 40° C. with brine systems. The low freezing temperature entails that the capacity of a given system is increased by about 40%.
