Measurement of performance of carbon dioxide compressors. Final report.

Author(s) : HUBACHER B., GROLL E. A.

Type of monograph: Report

Summary

The aim of this project was to measure the performance of two carbon dioxide prototype compressors using a compressor load stand and to develop compressor performance maps based on the experimental data. A compressor load stand was specifically designed and constructed for this purpose, which is based on a hot-gas bypass design and uses an oil-separator in the discharge line. The measured compressors were a semi-hermetic, two-piston, single-stage, reciprocating compressor with an estimated cooling capacityof 10.6 kW (3 tons of refrigeration) and a hermetic, two-stage, rotary compressor with an estimated cooling capacity of 2.8 kW (0.8 tons of refrigeration). A test matrix of 48 operating conditions was established. Extract from the table of contents: CO2-compressor background; test stand (design and performance, instrumentation, oil measurements); carbon dioxide grades; lubrication; analysis; single-stage, semi-hermetic compressor; two-stage, hermetic compressor.
