The invention provides a system for circularly supplying gas to a sealed cabin body in a vacuum environment. The system comprises a high-pressure oxygen tank, a first pressure reducing valve, a high-pressure nitrogen tank, a second pressure reducing valve, a waste gas treatment unit, an air conditioning device and a first power unit, wherein the first pressure reducing valve is connected with thehigh-pressure oxygen tank, the second pressure reducing valve is connected with the high-pressure nitrogen tank, the waste gas treatment unit is used for treating waste gas in the sealed cabin body and outputting residual oxygen and nitrogen, the air conditioning device is connected with the first pressure reducing valve, the second pressure reducing valve and the waste gas treatment unit, the airconditioning device is used for conducting pressure and flow adjustment on the oxygen and nitrogen subjected to pressure adjustment and the remaining oxygen and nitrogen, and the first power unit isused for sending the oxygen and nitrogen subjected to pressure and flow adjustment to the sealed cabin body. By adopting the technical scheme, the technical problem that a gas compressor is small in pressurization ratio and cannot meet the requirement of application occasions with a large pressurization ratio in the prior art is solved.
