HVAC P/T Chart
- A navigatable Pressure (PSIG) to Temperature (°F) conversion chart for the following commonly used HVAC/R refrigerants: R22 | R410a | R407c | R134a | R404a. View and navigate through a full list of refrigerant saturation P/T statistics for 5 commonly used refrigerants degree by degree between -14 °F and 500 °F including degree by degree saturation pressure (PSIG). All statistics are listed in view with no need to type and convert any readings
- just swipe up or down to navigate the chart and pinpoint the information you need!
Includes both dew point and bubble point statistics for refrigerants that have notable temperature glides.
USES:Useful app if your in the field and happen to be using a older manifold / pressure gauge that doesn't include the conversion chart on the gauge for each of the above refrigerants. Use for your troubleshooting and diagnostic purposes or even when filling out paper work.
Simply drag the screen/chart to your Pressure and Temperature selection of choice to view every respected conversion degree by degree between (°F) temperature and (PSIG) pressure.
HOW TO USE THIS APPLICATION: 1. Open the OpenHVAC P/T Chart application on your device.
2. Select from the 5 respected refrigerants listed via tabs at the top of the application to view that refrigerants P/T statistics.
3. Swipe up or down to navigate the selected refrigerant's P/T chart.
ABOUT:This program was written for the maintenance departments at the hospitals that I do HVAC work for as an aid for their diagnostic and learning purposes when they do their HVAC preventative maintenance inspections and also to help the maintenance departments fill out their paperwork. I noticed most of maintenace crew have old manifolds that only convert P/T for 2 or 3 refrigerants and also noticed they wont upgrade their tools so naturally when trouble calls come in on the weekends they often would call me to come diagnose a situation and with this chart instead of calling me and hearing the ole: "You have to go because I dont have a gauge that will show that one!" excuse, they can now easily use any manifold and navigate this simple chart and make the conversion and diagnose the problem themselves and it also makes troubleshooting HVAC issues over the phone much easier without the need to physically make a trip to the job site unless need be. More refrigerants are planned to be added as needed. Enjoy.

I teach HVAC. This is the easiest p/t app to teach. The number of refrigerants is limited but the students can not juggle a lot of info at first.
Looked good but outdated for current version of Android. Just crashes when I try to open it.
Does not work. App only for older version of Android.
gives pressures and correlating temps.
Apps is excellent.... Need °C Table with °F table Maximum people friendly understand with centigrade table so please add in centigrade table parallel format.
I usually use this app all the time for my job but now it won't open
well checked r134a 85 degree should be over 200 psi this thing shows 95 what a joke at least get it down right
Needs an update to work
Will not open on my phone
please get a updated edition
The set up is good easy touse and read I'll use it. The most common gases are there, but would like to have the lesser gas charted as well. Like the r22 subs. Doesn't work any more. Ask to be updated but there isn't one. Used 2 weeks ago now it will not open.
40 years as a tech. This app is the best I have seen. Plus it's free and as of today no advertisements. I would have paid to get an app like this. Thanks. For those who rated this app less then five stars. Shame on you. If you want more ask for more but don't under rate such a great app.
The app is OK, but it doesn't have enough refrigerant options and doesn't allow you to convert to degrees Celsius or to Kpa pressure, well at least not on my phone.
Lucky for me, the company I work for only knows two refrigerants. R22 90% of the time and R410a for the rest.
It's like having tickets to the world series & Super Bowl
Very nice and helpful
Very good app .thanks
Fast and easy to use.
Great tool!
Love it 😀
Needs more
Farienhiet wats that?
The app will no longer open up. This is a bummer as this is an amazing tool for my work. Amazing app when it is working properly. Just crashes now. Will rate 5 stars once it works again!
