摘要： 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.

摘要： 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.
