<p>Provided is a refrigeration cycle of a refrigerator. The refrigeration cycle of a refrigerator including a first refrigeration cycle in which a first refrigerant flows along a first refrigerant tube and a second refrigeration cycle in which a second refrigerant flows along a second refrigerant tube includes first and second compressors compressing each of the first and second refrigerants into a high-temperature highpressure gaseous refrigerant, a combined condenser condensing each of the first and second refrigerants passing through the first and second compressors into a high-temperature highpressure liquid refrigerant, first and second expansion valves phase-changing each of the first and second refrigerants passing through the combined condenser into a low-temperature low-pressure two-phase refrigerant, and first and second evaporators changing the refrigerant passing through each of the first and second expansion valves into a low-temperature low-pressure gaseous refrigerant. The combined condenser includes first and second condensation tubes constituting portions of the first and second refrigerant tubes that connect the first and second compressors to the first and second expansion valves, respectively and heat-exchange fins contacting surfaces of the first and second condensation tubes. The plurality of first and second condensation tubes are alternately parallely disposed in a width direction thereof.</p> |
