• Phase I — check valves closed, nominally adiabatic: compression on the L+H side;
• Phase II — heat exchange, nominally isothermal: transfer L → H → S, with heat rejection on the hot side;
• Phase III — check valves closed, nominally adiabatic: expansion on the S+C side;
• Phase IV — heat exchange, nominally isothermal: transfer S → C → L, with heat absorption on the cold side.
