FIELD: machine building.
SUBSTANCE: invention relates to cleaning of compressor, which comprises stage of compressor and which is intended for compression of working medium. Compressor stage uses dry ice for abrasive cleaning of compressor stage units during operation of working medium compression. Compressor stage receives liquid CO2, which is converted to dry ice and carrier gas by means of isoenthalpic expansion. Dry ice is directed by means of carrier gas to units of compressor stage for its abrasive cleaning.
EFFECT: removal of insoluble contaminants.
