The invention relates to the technical field of vapor compressors, in particular to an integral structure system of a centrifugal two-stage vapor compressor, which comprises a gear box, a first-stage volute, a first-stage impeller, a second-stage volute, a second-stage impeller, a sealing element and a vapor-liquid separator. The first-stage impeller and the second-stage impeller are fixed to the two ends of the rotating shaft respectively, a first-stage inlet and a first-stage outlet are formed in the first-stage volute, a second-stage inlet and a second-stage outlet are formed in the second-stage volute, the inlet end of the vapor-liquid separator is communicated with the first-stage outlet, and the outlet end of the vapor-liquid separator is communicated with the second-stage inlet. According to the scheme, the first-stage volute, the first-stage impeller, the second-stage volute and the second-stage impeller are arranged, first-stage compression and second-stage compression heating are conducted on steam,
