Abstract
A refrigeration cycle of a refrigerator includes 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. First and second compressors compress each of the first and second refrigerants, and a combined condenser condenses each of the first and second refrigerants. First and second expansion valves phase-change each of the first and second refrigerants passing through the combined condenser, and first and second evaporators change the refrigerant passing through each of the first and second expansion valves into a low-temperature low-pressure gaseous refrigerant.
