Beschreibung
Zusammenfassung:	To provide a Brayton cycle type refrigerating apparatus using multiple stages of compressors and having a good response without reduction in efficiency due to change in heat load of the object to be cooled, the Brayton cycle type refrigerating apparatus (100) according to the present invention comprises, on a refrigerant line (101), multiple stages of compressors (102a, 102b, 102c), a temperature sensor (160) for detecting heat load of an object to be cooled, and a buffer tank (111) provided between a low pressure line (109) and a high pressure line (110), wherein a flow rate of the refrigerant in the refrigerant line is controlled by controlling opening degrees of valves (112, 113) to adjust the cooling capacity.
