FIELD: turbines.
SUBSTANCE: invention discloses turbo-compressor generator sets (200, 300), containing compressors with high compression ratio and with more than one intercooling, and associated methods. Compressor (245, 345) with high compression ratio and with more than one intercooling includes housing (246, 346) with group of chambers (247, 248), at least, one shaft (265, 365), passing inside said chambers, and impellers (257, 258), accordingly mounted on said, at least, one shaft inside said chambers. Each chamber has gas inlet opening and gas outlet opening for enabling possibility of gas flow inlet into this chamber and outlet from it.
EFFECT: gas flow is sequentially compressed in each of said chambers and cooled outside of said housing at transition from one chamber to next chamber from said chambers.
