A refrigeration cycle of a refrigerator having two evaporators for precise temperature control is provided to realize independent operation of two evaporators connected in serial for precisely controlling temperature of freezing and refrigerating compartments. A refrigeration cycle of a refrigerator having two evaporators for precise temperature control includes a first evaporator(50) for evaporating refrigerant of a condenser, and a second evaporator(60) connected to the first one in serial for evaporating the refrigerant of the first evaporator. A first valve(80) is mounted between the condenser and the first evaporator for connection of a first or second pipe(81,82), wherein the first pipe supplies the refrigerant from the condenser to the first evaporator, and the second pipe supplies the refrigerant from the condenser to the second evaporator without passing through the first evaporator. A second valve(100) is mounted between the first and second evaporators for connection of a third or fourth pipe(101,102), wherein the third pipe supplies the refrigerant from the first evaporator to the second evaporator, and the fourth pipe supplies the refrigerant from the first evaporator to an outlet of the second evaporator without passing through the second evaporator.
