  • Publication number: 20100063634
    Abstract: There are provided a refrigerator and a method of controlling the same. When a difference between a temperature of an inside of a freezer compartment and a set temperature is referred to as a first error temperature and when a difference between a temperature of an inside of a refrigerator compartment and the set temperature is referred to as a second error temperature, the method of controlling a refrigerator includes varying stroke of an inverter linear compressor to operate the inverter linear compressor by a maximum output when the first or second error temperature is higher than a maximum output temperature and varying the stroke of the inverter linear compressor at least once in a freezer or refrigerator cycle one period to operate the inverter linear compressor when the first or second error temperature is no more than the maximum output temperature.

  • Patent number: 7140191
    Abstract: A direct cooling type refrigerator capable of rapidly and accurately controlling the temperature thereof, reducing the ON/OFF time of its compressor, thereby preventing the temperature deviation of its storage compartment from increasing over a predetermined value. The refrigerator includes an outer casing defining an appearance of the refrigerator, an inner casing arranged within the outer casing, and defined with a storage compartment, an insulator interposed between the outer casing and the inner casing, a compressor for compressing a refrigerant, an evaporator arranged to be in contact with the inner casing, and adapted to cool the inner casing in accordance with evaporation of a refrigerant passing therethrough, a temperature sensor provided with a surface contact area closely contacting the inner casing, and adapted to sense a temperature of the inner casing, and a control unit for controlling the compressor in accordance with the temperature sensed by the temperature sensor.

  • Publication number: 20050275326
    Abstract: A refrigerator including a cooling chamber in a main body, includes: a rack assembly installed inside the cooling chamber; and a rack assembly drawing unit for drawing/putting the rack assembly out of/into the cooling chamber. Accordingly, food containers put on a rack of a rack assembly can be easily and conveniently taken out or checked regardless their locations by constructing the rack assembly to be selectively drawn out of a cooling chamber. Also, by attaching a vibration preventing rubber material to an end of the rack assembly, the food container put on the rack is prevented from being dropped, and the vibration noise can be effectively prevented.
