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 includes a heat transfer unit, which transfers heat generated from a machine room within a refrigerator main body to a periphery of a home bar so as to remove dew formed at the periphery of the home bar, and an insulating unit for surrounding an outer circumference of the heat transfer unit. The refrigerator further includes a heating unit installed to be thermally conductive with the heat transfer unit, and a non-conductive cover for covering the heat transfer unit and the heating unit. Consequently, waste heat generated from the machine room, other than a separate power supply unit, can be used to prevent dew formation at the periphery of the home bar, so as to remarkably reduce power consumption.

摘要： A refrigerator and a driving method thereof are disclosed. A primary compressor and a secondary compressor can form independent cycles together with corresponding evaporators so as to reduce unnecessary power consumption. Also, a backflow prevention valve is installed between the primary and secondary compressors to prevent an increase in pressure of the secondary compressor, or an auxiliary heat exchanger is installed at the outlet side of a second evaporator with high temperature to allow heat exchange of an outlet side pipe of a first evaporator with low temperature so as to shift a load of a freezing chamber into a relatively large refrigerating chamber, thereby improving efficiency of the refrigerator. In addition, an oil separator or an oil collection pipe is installed at the outlet sides of the compressors or an oil balancing pipe and an oil balancing valve are installed between the compressors, so as to uniformly maintain an oil amount between the compressors.
