Beschreibung
Zusammenfassung:	There is disclosed a refrigeration device in which a cooling capability and efficiency can be improved by controlling a high pressure side pressure of a low stage side refrigerant circuit into an optimum value. A refrigeration device 1 includes a high stage side refrigerant circuit 4, first and second low stage side refrigerant circuits 6A and 6B, and cascade heat exchangers 43A and 43B to evaporate a refrigerant of the high stage side refrigerant circuit 4, thereby cooling high pressure side refrigerants of the low stage side refrigerant circuits 6A and 6B, and carbon dioxide is charged as the refrigerant in each of the refrigerant circuits 4, 6A and 6B, and in the device, there are disposed pressure adjusting expansion valves 31 to adjust high pressure side pressures of the low stage side refrigerant circuits 6A and 6B.
