A refrigeration-cycle apparatus is provided that includes a plurality of evaporators having various temperature bands, along with a refrigerator including a plurality of cooling compartments to enable stable and even cooling operations in various temperature bands using the plurality of evaporators. The refrigeration-cycle apparatus and the refrigerator enable individual operation of a portion of the plurality of evaporators, thereby reducing consumption of energy and enabling accurate control of an interior temperature of the refrigerator. The refrigeration-cycle apparatus includes a compressor that compresses and discharges a refrigerant, a condensing device including at least one condenser that condenses the refrigerant discharged from the compressor, a distributor that distributes the refrigerant condensed in the condensing device, and a cold air generator including a plurality of evaporators that evaporates the refrigerant distributed by the distributor. The plurality of evaporators is connected in series and parallel to one another and operates, respectively, to generate cold air having different temperature bands from one another.
