20120312034 | REFRIGERATING CYCLE APPARATUS AND METHOD FOR OPERATING THE SAME - A refrigerating cycle apparatus and a method of operating the same are provided. For a refrigerating cycle having a plurality of compressors connected in series for multi-stage compression, an inner space of each compressor and a pipe of the refrigerating cycle may be connected via an oil collection pipe, and oil may be discharged into the refrigerating cycle by pressure reversal during a pressure balancing operation, so as to allow the discharged oil to be collected into a high-stage compressor or a low-stage compressor. Accordingly, an amount of oil may be uniformly maintained in each of the plurality of compressors to prevent losses due to friction and/or increases in power consumption due to a lack of oil in one or more of the compressors. The structure of a device and pipes for performing oil balancing between the compressors may be simplified to enhance efficiency of the compressors. | 12-13-2012 |
20140116083 | REFRIGERATOR - A refrigerator may include a compressor to compress a refrigerant, a condenser to condense the refrigerant having passed through compressor, a capillary tube to lower a temperature and a pressure of the refrigerant having passed though the condenser, an evaporator to evaporate the refrigerant having passed through the capillary tube, and a heat exchanger coupled to a refrigerant pipe connected to the compressor to cool the refrigerant in the refrigerant pipe. With components so arranged, operational efficiency of the refrigerator may be enhanced, and energy may be saved. | 05-01-2014 |
20140220880 | SHROUD FOR REFRIGERATOR - There is disclosed a shroud for a refrigerator including a blower for generating air flow; a first region arranged on the right of the blower, the first region comprising an outlet hole for a first storage chamber for exhausting cold air to the first storage chamber; a second region arranged on the left of the blower, the second region comprising an outlet hole for a second storage chamber for exhausting cold air to the second storage; a third region arranged under the blower, the third region comprising an outlet hole for the second storage chamber; and a first guide arranged between the second region and the third region, projected closer to a rotational center of the blower, to guide air flow. | 08-07-2014 |
20150027148 | HEAT EXCHANGER ASSEMBLY, REFRIGERATOR, AND METHOD OF CONTROLLING A REFRIGERATOR - A heat exchanger assembly, a refrigerator, and a method of controlling a refrigerator are provided.

20150027678 | HEAT EXCHANGER AND METHOD AND APPARATUS FOR MANUFACTURING THE SAME - A heat exchanger and a method and apparatus for manufacturing the same are provided. The heat exchanger may include a refrigerant tube, through which a refrigerant may flow, at least one heat-exchange fin, into which the refrigerant tube may be inserted, a plurality of tube treatments provided on a surface of the refrigerant tube, and a plurality of fin treatments provided on a surface of the at least one heat-exchange fin. | 01-29-2015 |
20150040591 | REFRIGERATOR AND CONTROL METHOD THEREOF - Provided are a refrigerator and a control method thereof. The refrigerator includes a compressor, a condenser, a refrigerant tube guiding a flow of the refrigerant condensed in the condenser, a plurality of expansion devices, a plurality of evaporators including first and second evaporators to evaporate the refrigerant decompressed in the plurality of expansion devices, a plurality of first evaporation passages in which a portion of the plurality of expansion devices is disposed, the plurality of first evaporation passages guiding introduction of the refrigerant into the first evaporator of the plurality of evaporators, a second evaporation passage in which the other portion of the plurality of expansion devices is disposed, the second evaporation passage guiding introduction of the refrigerant into the second evaporator and a flow adjusting unit to branch the refrigerant into the plurality of first evaporation passages and the second evaporation passage. | 02-12-2015 |
20150059370 | REFRIGERATOR AND METHOD OF CONTROLLING A REFRIGERATOR - A refrigerator and a method of controlling a refrigerator are provided. The refrigerator may include a machine room defined in or at one side of a storage compartment, a base that defines a bottom surface of the machine room, a compressor seated on the base to compress a refrigerant, a condenser that condenses a refrigerant compressed in the compressor, the condenser being disposed on or at one side of the compressor, a drain pan disposed on the base to store condensed water generated in the condenser, and a fan assembly coupled to the base to generate an air flow within the machine room. The fan assembly may include a plurality of condensation fans. | 03-05-2015 |
