HVAC PT Buddy contains Pressure Temperature relationships for over 100 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.
Core Functionality:
• Pressure / temperature relationships
• One degree Increments
• Fahrenheit and Celsius
• Last refrigerant selection recall

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
Additional information:
• Chemical Name
• Formula
• Ozone depletion potential (ODP)
• global warming potential (GWP)
• molecular mass
