20090081054 | Structure of Discharging Refrigerant For Linear Compressor - The present invention discloses a linear compressor in which a piston is linearly reciprocated inside a cylinder, for sicking a refrigerant into a compression space between the piston and the cylinder, and compressing and discharging the refrigerant, and especially, a structure of discharging the refrigerant for the linear compressor which can reduce a pulsation of a high pressure discharged refrigerant, by making the refrigerant compressed in the compression space flow from a sub-discharge space with a relatively small volume to a sub-discharge space with a relatively large volume in a discharge chamber. As a result, the structure of discharging the refrigerant for the linear compressor can efficiently reduce noise and vibration. | 03-26-2009 |
20090113902 | CONTROL METHOD FOR A REFRIGERATOR - A refrigerator control method is provided that may efficiently perform a defrosting operation. The method includes performing a normal operation of a refrigerating storage room and a normal operation of a freezing storage room selectively or simultaneously, setting a variable defrosting period, which is varied according to set parameters including the relative humidity of external air, and performing a defrosting operation based on the set defrosting period. | 05-07-2009 |
20090113904 | METHOD FOR CONTROLLING A REFRIGERATOR - A refrigerator control method is disclosed which ensures efficient operation of a compressor. To control a refrigerator including a compressor, a first evaporator and a second evaporator connected to the compressor, and a refrigerant control valve that controls introduction of a refrigerant into the first evaporator and the second evaporator, the refrigerator control method includes operating the compressor, and controlling the opening and closing of the refrigerant control valve, to reduce not only consumption of electricity by the compressor, but also a pressure difference between an entrance and an exit of the compressor upon starting of the compressor. | 05-07-2009 |
20100125365 | REFRIGERATOR AND METHOD OF CONTROLLING SAME - A refrigerator is provided. The refrigerator may include a freezing chamber positioned under a refrigerating chamber. A refrigerating chamber fan and a freezing chamber fan may be provided at a refrigerating chamber duct and a freezing chamber duct, respectively, and a damper may selectively open and close the refrigerating chamber duct. By controlling the refrigerating chamber fan, the freezing chamber fan and the damper, cold air may be selectively supplied to the refrigerating chamber and/or the freezing chamber based on individual cooling needs as appropriate. | 05-20-2010 |
20100126185 | REFRIGERATOR - A refrigerator is provided. The refrigerator may include a body having a storage room, an ice making chamber formed separately from the storage room, and a thermoelectric-module provided in the ice making chamber to generate cold air. The thermoelectric-module does not require a cold air duct to cool the ice making chamber. As a result, space utilization is improved and a capacity of the refrigerator is improved. In addition, energy efficiency may be enhanced because a heater is not required to remove the frost from a cold air duct. | 05-27-2010 |
20100154461 | REFRIGERATOR - 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. | 06-24-2010 |
20100162744 | REFRIGERATOR - 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. | 07-01-2010 |
20100192622 | REFRIGERATING SYSTEM - 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. | 08-05-2010 |
20100287961 | REFRIGERATOR AND CONTROL METHOD FOR THE SAME - A refrigerator and a control method of the same are disclosed. A refrigerator includes a plurality of evaporators and a refrigerant path conversion device connected with the plurality of the evaporates, the refrigerant path conversion device controlling a path of refrigerant to perform defrosting operations for predetermined evaporators and cooling operations for the other evaporators. | 11-18-2010 |
20110011106 | REFRIGERATOR - A refrigerator having a refrigerator body including a first cooling chamber and a second cooling chamber, a barrier wall located between the first cooling chamber and the second cooling chamber, an evaporator configured to provide cooling air, a first cooling fan configured to provide cooling air of the evaporator to the first cooling chamber, and a second cooling fan configured to provide cooling air of the evaporator to the second cooling chamber is provided. A method of providing cooling air flow in a refrigerator is also provided. | 01-20-2011 |
20110011118 | REFRIGERATOR - A refrigerator is provided, including a refrigerator body having first and second cooling chambers formed therein, partitioned by a barrier wall, an evaporator provided within the barrier wall, a first cooling fan disposed at one side of the evaporator to blow cooling air into the first cooling chamber, and a second cooling fan provided at the other side of the evaporator to blow cooling air to the second cooling chamber. First and second suction openings are formed at upper and lower surfaces of the barrier wall, respectively, such that air drawn into the barrier wall through the first and second suction openings are brought into contact with different regions of the evaporator and is not mixed, so that the first and second cooling chambers may be separately or simultaneously cooled to appropriate temperatures. | 01-20-2011 |
