R1233zd Ph Diagram Page

If you work with or centrifugal chillers , you’ve likely encountered R1233zd(E) — a non-flammable, low-GWP replacement for R123.

But to unlock its full potential, you need to understand its . Here’s a quick breakdown 👇 r1233zd ph diagram

🔍 It maps refrigerant state changes (compression, condensation, expansion, evaporation) in a single view. The x-axis = enthalpy (heat content), y-axis = log pressure . If you work with or centrifugal chillers ,

✅ – 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. The x-axis = enthalpy (heat content), y-axis = log pressure

Let’s discuss below 👇

❓ Do you use R1233zd in retrofits or new machines? Have you used its ph diagram for performance tuning?
