If you work with or centrifugal chillers , you’ve likely encountered R1233zd(E) — a non-flammable, low-GWP replacement for R123.
✅ – Plotting actual chiller conditions on the ph diagram reveals subcooling, superheat, and isentropic efficiency. ✅ Component sizing – Enthalpy differences determine evaporator & condenser loads. ✅ Troubleshooting – Off-design points (e.g., low delta T, flooding) become visible immediately. r1233zd ph diagram
❓ Do you use R1233zd in retrofits or new machines? Have you used its ph diagram for performance tuning? If you work with or centrifugal chillers ,
