  • Publication number: 20100192622
    Abstract: A refrigerating system is disclosed. Since heat exchange is performed between first and second evaporators by a heat exchanging unit, the first and second evaporators have temperatures similar to each other, thereby requiring no additional ‘pump-down’ operation. Also, a compressor does not have a discharge occurrence owing to no additional ‘pump-down’ operation, thereby having no loss and an enhanced reliability. Besides, since no additional pump-down operation is required, power consumption for operating the compressor so as to collect a remaining refrigerant is reduced. Accordingly, the efficiency of the refrigerating system is enhanced. Furthermore, as the ‘pump-down’ operation is not required, a backflow preventing unit for preventing a refrigerant collected from an evaporator from backflowing to the evaporator is not required. Accordingly, the fabrication cost is reduced.

  • Publication number: 20100162744
    Abstract: A refrigerator is disclosed. A freezing chamber evaporator and a cooling chamber evaporator are installed at an inner side of a ceiling surface of a freezing chamber and a cooling chamber. Accordingly, the freezing chamber and the cooling chamber have deeper depths thus to have large available capacities, thereby freshly receiving a large amount of food items. Furthermore, a cool air channel is formed at the freezing chamber door and the cooling chamber door so as to be connected to a cool air channel of the ceiling surface. Accordingly, a temperature difference between an inner space and a door basket does not occur, thereby storing food or beverage items received in the door basket in a fresh condition.

  • Publication number: 20100154461
    Abstract: A refrigerator is disclosed. A freezing chamber evaporator and a chilling chamber evaporator are installed at an inner side of a partition wall that partitions a freezing chamber and a chilling chamber from each other. Accordingly, the freezing chamber and the chilling chamber have deep depths thus to have large available capacities, thereby freshly receiving a large amount of food items. Furthermore, a cool air channel is formed at the freezing chamber door and the chilling chamber door so as to be connected to a cool air channel of the partition wall. Accordingly, a temperature difference between an inner space and a door basket does not occur, thereby storing food or beverage items received in the door basket with a fresh state.

  • Publication number: 20100126205
    Abstract: A refrigerator is provided. The refrigerator may include a cold air generation chamber provided in a body of the refrigerator, the cold air generation chamber having an evaporator installed therein. A cold air duct may form a path through which cold air generated in the cold air generation chamber is circulated to a freezer compartment, and a quick freezer compartment. The quick freezer compartment may be connected with the cold air duct, and may be positioned substantially nearer to the evaporator than the freezer compartment. A damper may be installed in the cold air duct to selectively shut off the flow of cold air to the freezer compartment. The quick freezer compartment may be quickly cooled using cold air directly supplied from the cold air generation chamber. Furthermore, cold air may be directed into the quick freezer compartment by selectively shutting off the supply of cold air into the freezer or refrigerator compartment.
