Physical properties of refrigerants - molecular weight, boiling, freezing and critical points. Refrigerants - Saturation Pressures vs. Temperatures Temperature and pressure diagram for constant boiling refrigerants - imperial and SI units.
R134A PT chart is a standard table. Basically, this 134A PT chart tells you what is the pressure of R134A refrigerant at certain temperatures. The charts start at the low end (-49°F) and tell you the pressures all the way to the high end (150°F).
