On a 90 degree day, the LOW side reading should be about 70 psi or higher. If the LOW gauge reading is less than this, the A/C system probably needs some additional refrigerant. The actual pressure readings will vary depending on the type of refrigerant (R-134a or R-1234yf) that is in your A/C system. Oct 16, 2013 · Automotive HVAC Pressure Diagnostics...

Following the instructions on the refrigerant package, add refrigerant to the system. 6. Charge the System. After determining the correct pressures using the ambient air pressure chart, monitor the pressure readings constantly while charging the system. If the system was low, your AC compressor clutch will not engage.

Let’s do an example. A walk-in fridge or reach-in fridge with R22 has a desired box temp is 38*F. What is 38*F on a P/T Chart? Around 63 PSI. But we don’t want 38*F, we want 28*F. So what’s 28*F? Around 49-50 PSI. So the suction side should be around ...R-1234yf Refrigerant PT Chart. March 20, 2019 by Alec Johnson. The HFO R-1234yf is the refrigerant of the future. Or, at least, that is how it has been marketed. Yf was the first HFO refrigerant to see mainstream attention. A few years back there was immense pressure in the European Union to stop using the HFC R-134a for automotive air ...
