To provide a carbon dioxide gas refrigeration cycle using carbon dioxide gas as the coolant, wherein at such time as the main body of the cycle 2 shuts down, particularly under conditions of high temperature, it is possible to inhibit increases in internal pressure, and wherein when using a buffer tank 11 to inhibit increases in internal pressure at such time as the main body of the cycle 2 shuts down, it is possible to avoid excessive size of said buffer tank 11 and to lessen the amount of coolant required to fill it. Solution A carbon dioxide gas refrigeration cycle wherein a compressor 4 circulates a coolant within the main body of the cycle 2, carbon dioxide gas being used as this coolant, wherein it has a buffer tank 11, which is separate from the main body of the cycle 2 and capable of containing the carbon dioxide gas, this buffer tank 11 being capable of coupling to the main body of the cycle 2 at such time as the compressor 4 shuts down. <IMAGE>
