HVAC PT Buddy contains Pressure Temperature relationships for 95 refrigerants in both Metric and English units in one degree increments. All refrigerant blends have bubble and dew points on the same line. To better indicate temperature glide R404a, R407c, and R410a show both temperatures for the same pressure on one line. For most of the current common refrigerants you can also view several additional thermodynamic properties enthalpy, entropy, specific heat, etc. Each refrigerant has chemical name, boiling point, critical pressure, critical temperature.
In short, this is the most comprehensive list of refrigerant properties available.

Metric and Imperial expanded thermodynamic properties include:
Bubble and Dew temp
Pressure (psia / MPa)
Density of Liquid
Volume of Vapor
Enthalpy of Liquid and Vapor
Entropy of Liquid and Vapor
Specific Heat of Liquid and Vapor
These properties are available by tapping on the pressure temperature row.
Notes on Refrigerant Blends:
Bubble and dew points combined on one line for all blends
R404a, R407c, and R410a key on pressure to better indicate temperature glide
Ozone depletion potential (ODP)
global warming potential (GWP)
Roughly a fourth of the refrigerants have additional information including color code, lubricants, etc.
