Beschreibung
Zusammenfassung:FIELD: refrigeration engineering. ^ SUBSTANCE: multicomponent refrigerant suitable preferably for one-loop refrigeration systems with single-step compressor contains 0.30-0.60 mol methane as low-boiling component, 0.10-0.70 mol middle-boiling component such as tetrafluoromethane, trifluoromethane, octafluoropropane and octafluorocyclobutane, and 0.05-0.30 mol high-boiling alkane component such n-pentane, isopentane, n-hexane, or binary mixtures thereof. ^ EFFECT: increased specific cold productivity and energetic efficiency of system within temperature range from -120 to -80°C, and increased service time of system. ^ 6 cl, 2 dwg, 1 tbl
