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 • Quick jump to top and bottom of list Refrigerants: R-11, R-12, R-13, R-13b1, R-21, R-22, R-23, R-32, R-113, R-114, R-115, R-116, R-123, R-124, R-125, R-134a, R-E134, R-141b, R-142b, R-143a, R-152a, R-170, R-E170, R-218, R-227ea, R-236ea, R-236fa, R-245ca, R-245cb, R-245fa, R-E245fa1, R-C270, R-290, R-C318, R-400-(50/50), R-400-(60/40), R-401A, R-401B, R-401C, R-402A, R-402B, R-403A, R-403B, R-404a, R-406A, R-407A, R-407B, R-407c, R-407D, R-408A, R-409A, R-410a, R-410B, R-411A, R-411B, R-412A, R-413A, R-414A, R-414B, R-415A, R-416A, R-417A, R-420A, R-421A, R-422A, R-422B, R-422C, R-422D, R-500, R-501, R-502, R-503, R-504, R-507a, R-507, R-508B, R-509A, R-600, R-600a, R-601, R-601a, R-717, R-718, R-744, R-1150, R-1270, FR-12, FX-220, FX-40, G2018c, GHG-HP, GHG-X5, HX4, NARM-12, NARM-22 Additional expanded thermodynamic properties are available at each pressure / temperature combination for the following refrigerants: R12, R22, R23, R32, R123, R124, R125, R134a, R143a, R152a, R170, R245fa, R290, R404a, R407c, R410a, R507a, R600, R600a, R717, R718, R744, R1150, and R1270 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 • boiling point • critical pressure • critical temperature Roughly a fourth of the refrigerants have additional information including color code, lubricants, etc. About: HVAC PT Buddy is part of the HVACBuddy Suite of applications for the HVAC/R industry.

Need updates
Was ok but now it’s quit working because there’s new no update available
When will this app be updated?!?!
I have paid for this app and it’s not being updated, along with several other apps by Kevin Burandt, that were paid for (in good faith) so that they would be maintained by the developer. When will they be updated?!?!
Update please
It was a good app for the price but when my iPhone updated the app is worthless, please take care of your clients and update your app.
UPDATE REQUIRED FROM DEVELOPER
Great in the past but developer hasn’t updated the app to work on iOS version 11+.
Update your apps please
I bought a bundle of your apps and I love them, they help my daily work load. Now that my IPhone was updated to iOS 11.1 I can no longer use what I paid for. PLEASE UPDATE.
Needs updated
All of this developers apps are really good but they do not work with ios11. Please update
Inaccurate!
Both 409a and 416a are off by several degrees. This isn't horseshoes or hand grenades, it's refrigeration and must be accurate or it's worthless! This app has potential but must be corrected to be useful and trusted in the field.
Quickly change between refrigerants directly from the PT chart.
