Abstract

A possibility of development of a unified family of compressors with various refrigw capacities and pressure ratios on the basis of one baseline full-size axial compressor hai^ maximum number of stages is shown. This makes it possible to implement a re/r^eJ cycle with one compressor and much simpler vapor supply to intermediate stages than* the use of centrifugal compressors
