R1233zd Ph Diagram ((better)) Review

Because R1233zd is low pressure, its density is low. The compressor must be physically larger (or run faster) to move the same mass flow rate as R134a. On the Ph diagram, look at the specific volume (v) lines. At the suction point (4°C), specific volume for R1233zd is ~5 m³/kg, versus ~0.05 m³/kg for R134a. Your compressor displacement must be 100x larger!

. Because it is a single-component fluid, it exhibits zero temperature glide during phase changes, meaning the saturated liquid and vapor lines meet cleanly at the critical point without the shifting temperatures seen in many blends. 2. Analyze the Saturation Bell r1233zd ph diagram
