Discharge process analysis of screw refrigeration compressor with different refrigerants
Annotation
Two stages of process when internal pressure is lower then discharge pressure is considered. Considered compressor operation composed of medium-temperature chiller at refrigerant R717 and R404a. Provides efficiency indicators, relative resistance in discharge process, relative energy loss in inflow process from discharge port depending on volume ratio. In medium-temperature chiller mode energy efficiency of screw compressor on refrigerant R717 above then on R404а ofall volume ratios.
