Test on a twin-screw compressor: comparison between two cooling modes.

Author(s) : DUCRUET C., HIVET B., BOONE J., TORREILLES M.

Summary

An open twin-screw compressor supporting two distinct cooling modes (by external oil cooling or liquid injection into the compressor) has been tested with HCFC-22 and an alkylbenzene lubricant. The test procedure was as specified in the ISO 917 standard (testing of refrigerant compressors). Using both cooling methods, compressor efficiencies for evaporation from -35 to -5 deg C, condensation from 30 to 47 deg C, and discharge superheat of 35 K are determined. To conclude the study, compressor cooling needs for different values of discharge superheat and of compressor capacities are analysed.
