Car AC Pressure Chart for diagnosing refrigerant.One of the first refrigerants to go was our friend R-12. At this point in time, in the early 1990’s, R-12 had seen the majority of it’s usage in automobile air conditioning. R-12 was banned in new automobiles and was replaced with by the HFC refrigerant we all know today as R-134a. Now, there are still some R-12 applications out there today.AC System Diagnostics - Operating Pressures R134A. However, to perform the right measurements, the system must be in operational condition. This requires a correct level of refrigerant charge. (at least 1,5/25 PSI to run the compressor). Before the vehicle is started, the static system pressure should be read.

systems, some other R-134a applications, and it is a component in some HFC blends to help lower the overall GWP.

R-410A has a GWP of over two-thousand whereas R-32 has a GWP of only six-hundred and seventy-five. While R-32 isn’t perfect it is a lot better then R-410A. That is why we are beginning to see a rise of usage of R-32 in the European Union and here in the United …Acceptable operating pressure ranges for Vintage Air systems (R134a): High-side pressure: 160 to 250 PSI. NOTE: A general rule of thumb is two times the ambient (daytime) temperature, plus 15 to 20%. Low-side pressure: 6 to 18 PSI in a steady state. Center duct temperature: 36 to 46° F. Charge as follows: R134a = 1.8 lb.In an automotive AC System, a pressurized refrigerant continuously changes from liquid to gas and gas to liquid in a closed loop. The pressure of the refrigerant directly correlates with the temperature. Based on the pressure of the refrigerant at any particular point in the loop, the whole system can be divided into High-Pressure Side and Low ... HVAC App to Calculate Subcooling.
