Until now, no universally accepted method for determining compressor efficiency has been established; therefore, comparing compressors of different sizes and systems based on test data is extremely difficult, since each experimenter adheres to their own approach. In what follows, the author attempts to establish rational principles for determining compressor efficiency, such that the comparison of results obtained in individual cases would not present difficulties.
