Measuring The Pressure Of R134A Refrigerant On A Hot Summer Day.

The pressures in the pt chart are expressed in psig or gauge pressure. Low pressures in evaporator (low side) and condenser (high side)

This Can Be Helpful In A/C Diagnosis.

Mvac systems that are low on refrigerant will have: An r134a temperature‐pressure chart shows what the refrigerant temperature should be at a specific pressure.

We Always Use A Pressure Gauge Meter When Measuring The Pressure In Refrigerant Lines.
