MIXED REFRIGERANT COMPRESSION CIRCUIT

摘要

A refrigerant circuit is described. The circuit comprises: a first compression stage for compressing a mixed refrigerant gas, the first compression stage comprising at least a first compressor body and a second parallel compressor body, each compressor body having a suction inlet and an outlet; a first distribution means for splitting the flow of refrigerant gas to the first stage of compression across the at least two parallel compressor bodies, such that a first stream of refrigerant gas is fed to the suction inlet of the first compressor body and a second stream of refrigerant gas is fed to the suction inlet of the second compressor body; a second compression stage for compressing the mixed refrigerant gas; and, a first merging means for recombining the first stream of refrigerant gas with the second stream of refrigerant gas downstream of the first compression stage for delivery to the second compression stage.
