FIELD: machine engineering.
SUBSTANCE: device for compressing the gaseous refrigerant, for using in the refrigerating circuit of the liquefaction system, that contains the refrigeration circuit and two compressors, that are functionally connected to the refrigeration circuit. One of the compressors is provided in the double suction configuration, and the outlets and inlets of the first and the second compressors are connected, at least in part, in configuration with mutually parallel flows in such a way, that the refrigerant flow, that leaves the refrigerating circuit through the plurality of its outlets, is distributed between two compressors before joining at the refrigeration circuit inlet.
EFFECT: reduction of the sizes and increase of the output performance.
