Noskov A.N., Potapova D.V.
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.
