Abstract
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 high-pressure gaseous refrigerant, a combined condenser condensing each of the first and second refrigerants passing through the first and second compressors into a high-temperature high-pressure 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.
