An exergy method for compressor performance analysis.

Author(s) : MCGOVERN J. A., HARTE S.

Type of article: Article, IJR article

Summary

An exergy method for compressor performance analysis is presented. The purpose of this is to identify and quantify defects in the use of a compressor's shaft power. The defects are attributed to friction, irreversible heat transfer, fluid throttling, and irreversible fluid mixing. It is most readily applied where a detailed computer simulation program is available for the compressor. An analysis of an open reciprocating refrigeration compressor that used R12 is given as an example. The results that are presented consist of graphs of the instantaneous rates of exergy destruction according to the mechanisms involved, a pie chart of the breakdown of the average shaft power wastage by mechanism, and a pie chart with a breakdown by location.
