  • Patent number: 9650260
    Abstract: The invention relates to a desalination method and system that uses freeze crystallization technology that incorporates the use of compressed air energy as the source for freezing temperatures. When compressed air is released by a turbo expander, chilled air is produced as a by-product, wherein the chilled air is introduced into a chamber, wherein a spray cloud of seawater droplets, which has been pre-chilled by heat exchange with the cold chamber walls, is then circulated and exposed to the chilled air in the chamber. The droplets then settle at the bottom of the chamber, wherein they are deposited at slightly above the eutectic temperature, to form an ice/brine slush mixture. A slush removal mechanism with a screw-like helical blade is provided to continuously remove the ice particles from the chamber.

  • Publication number: 20140260349
    Abstract: A novel control logic for an individual cube spray type ice machine. The duration of the freeze cycle is able to adapt to changes in inlet water temperature, changes in ambient air temperature, and the impact of warm temperatures of internal ice making parts within the ice machine due to off cycle periods. This is accomplished through a combination of starting a freeze time period only after the water temperature for the volume of water circulating over the evaporator has reached approximately 32° F., and a freeze time period value that is a function of the refrigerant temperature leaving the condenser at the time where the water reaches approximately 32° F.

Furthermore, if the icemaker is installed in the freezing chamber of the refrigerator in which the refrigerating chamber is formed at a lower portion thereof and a refrigerating chamber is formed at an upper portion thereof, there is another problem in that it is difficult to control the temperature in the refrigerating chamber or ice-making capability of the icemaker is lowered. The present invention is directed to a refrigerator.

  • Patent number: 7484373
    Abstract: An apparatus (10) for making snow or a snow-like substance includes a container (12) having a cooling space (13) adapted to contain pressurized air or gas of above atmospheric pressure. At least one flexible walled vessel (14) extends through the cooling space (13) and is connectable to a water source. The apparatus (10) is operable to maintain the cooling space at a sufficiently low temperature to at least partially freeze the water within the flexible walled vessel (14). As a preferred feature of the snow making apparatus, the apparatus may be adapted to maintain a static pressure within the cooling space of the container (12) and to periodically and temporarily increase the pressure within the cooling space to compress the flexible walled vessel (14). Invention also resides in an apparatus (10) for making snow or a snow-like substance, the apparatus including at least one flexible walled vessel (14) connectable to a water source.

  • Publication number: 20080282712
    Abstract: A method and apparatus facilitate lowering the temperature of a cooling module positioned in heat exchange relation to a loaded container to be maintained at a low temperature. The module establishes convective air flow in heat exchange relation to the load without the use of forced air circulation. The module is self-contained and externally accessible to supply water and liquid CO2 to the module interior. Expansion and change in state of the liquid CO2 lowers the temperature of a water ice and CO2 snow mixture in the module. By continuing inflow of CO2 after terminating inflow of water, the mixture can be cooled from about ?76° F. to about ?117° F. Convective air flow in heat exchange relation to the module walls circulates cooling air, thereby eliminating any direct contact of products with the liquid CO2 or CO2 snow formed by the expanding refrigerant.

  • Publication number: 20080216490
    Abstract: Disclosed is an automatic ice maker which surely removes ice cubes from an ice-making unit and improves an ice-making efficiency. When the automatic ice maker starts a deicing operation, a hot gas is supplied to an evaporator and deicing water is supplied to the ice-making unit from a deicing water sprinkler to turn the frozen state at the frozen surfaces between the ice-making unit and ice cubes to a liquefaction state. When the deicing operation makes some progression and a temperature detecting unit detects that the temperature of the evaporator has reached a set temperature, a circulation pump is driven after elapse of the first set temperature to supply ice-making water to the ice-making unit from an ice-making sprinkler, promoting further separation of the ice cubes.

  • Patent number: 7415833
    Abstract: A control system for an icemaker for an ice/beverage dispenser is responsive to both a sensed level of ice in an ice bin of the dispenser and to a customer ice usage profile to operate the icemaker at such times as to build ice for the ice bin just before and in sufficient time and quantity to meet an anticipated demand for ice. The control system may be programmed manually or automatically through use of adaptive algorithms, with ice usage patterns that identify the days and times of day when demands for ice will occur, and the control system then operates the icemaker in accordance with such ice usage patterns.

  • Patent number: 7406831
    Abstract: A process for the manufacture of the ice cups in which a condensation plate able to receive water spray for the formation of the ice elements is cooled for a predetermined period of time such as to cause freezing of the water and the subsequent formation of ice elements. When cooling is interrupted the plate is heated for a predetermined interval of time to permit detachment of the ice elements. Between the interruption of cooling and the start of heating the plate is subjected to a plurality of heating stages of increasing duration alternating with a plurality of cooling stage of decreasing duration.

    Abstract: The invention is an apparatus and method of creating and preserving an outdoor frozen surface by covering a defined outdoor surface with a layer of white base paper after clearing debris, litter, and other objects from the defined surface which may present a hazardous condition on an ice surface. The layer of white base paper is saturated with water at near freezing or under freezing conditions to allow the water to freeze and hold the white base paper to the defined outdoor surface. Thereafter, water is continuously dispensed under freezing conditions to build up a predefined thickness ice layer on the defined outdoor surface.

  • Patent number: 7281385
    Abstract: In an ice making plate where a plurality of ice making regions are formed in the vertical direction, a projecting portion having a lateral width B smaller than a lateral width A of the ice making regions is formed between adjacent ice making regions. At least one non-projecting portion or area is defined at least one side of the projecting portion and located between adjacent ice making regions. Most of the ice growth is restricted by an upper surface portion and a lower surface portion of the projecting portion, and the ice is thereby partially prevented from connecting to the ice formed in the adjacent ice making region. However, a part of the ice grows in the at least one non-projecting portion or area, and partially connected ice is formed by the connection of the ice formed in the non-projecting portion or area to the ice grown in the adjacent ice making region. The partially connected ice is dropped as an integrated whole from the ice making plate.
