REVIEW OF COMPRESSOR MODELS AND PERFORMANCE CHARACTERIZING VARIABLES

Abstract

In this paper a method for categorization of compressor models is presented.The method is used in connection with a review of the compressor models presented in proceedings of the International Compressor Engineering Conferences at Purdue during the last 8 years.Trends in the development, purpose and use of compressor models are identified and discussed.The traditional use of system-oriented variables like COP for describing the compressor performance has to some extent caused "confusion" when evaluating/comparing compressors.The different ways of describing the performance characteristics of a compressor is discussed and the general recommendations regarding the choice of performance characterizing variables is given.
