PROBLEM TO BE SOLVED: To provide a refrigeration apparatus capable of being operated with high efficiency by keeping its efficiency from decreasing in any temperature zone if endothermic means functioning selectively in different temperature zones are provided in a refrigeration cycle. SOLUTION: The refrigeration apparatus 30 comprises a compressor 1, a heat radiator 2, a first endothermic means 10, and a second endothermic means 11 provided in parallel with the first endothermic means 10. The first endothermic means 10 comprises first pressure reducing means 12, 65, a first heat sink 57, and a first heat exchanger 17 configured to allow heat exchange between refrigerant flowing out of the first heat sink 57 and refrigerant flowing in the first pressure reducing means 12. The second endothermic means 11 comprises second pressure reducing means 13, 66, a second heat sink 58, and a second heat exchanger 18 configured to allow heat exchange between refrigerator flowing out of the second heat sink 58 and refrigerant flowing in the second pressure reducing means 13.
