Ac Pressure Readings. Find quick and easy help to interpret your pressure reading. By micheal shawn updated on october 26, 2022 there are a few reasons why your car’s ac gauge may be going up and down.
Interpreting AC Pressure Readings
The temperature and pressure of the refrigerant have a direct relationship. This pressure chart has three different columns within a table and it has all the readings on it. Web the gauge displays different pressure readings during operation and to interpret those readings against temperature, you will need a pressure chart, or an r134 pressure chart to be precise. Low pressure readings decrease or a negative reading is shown. Needs service, possibly faulty compressor. Need service, possible blockage of the expansion valve or orifice tube. This occurs as a result of inadequate system maintenance or an acid reaction inside the system, resulting in a burned coil. If r134a is released into a room at atmospheric pressure and room temperature, it would instantly turn into gas. The gauge images below show normal ac pressure gauge readings for an operational auto ac system. 250 psi / 30 psi = you have air somewhere in the system.
