Thermodynamic cycles of compound refrigeration units in T-s diagrams: a - cycle with two-stage compression and threefold throttling (three boiling temperatures); b - cycle with three-stage compression and threefold throttling (three boiling temperatures); c - cycle with two-stage compression and twofold throttling (four boiling temperatures with one intermediate pressure); d - cycle with two-stage compression and twofold throttling (four boiling temperatures with two intermediate pressures)
