In the R134a, pressure can be determined at any temperature that ranges between -22 to 202 degrees Fahrenheit. This can be done by reading from the pressure-temperature chart on the refrigerator. Refrigerators using R134a refrigerants are designed to operate under moderate and higher temperatures. That's why they are suitable even in places. At the lowest temperature, the coil in an R134a system should run at 22 pounds per square inch, which is 45-20, 25 degrees Fahrenheit. At the highest temperature, the R 134a operating pressures should be 57 pounds per square inch, which is 60-20,40 degrees Fahrenheit. The normal R 134a operating pressures was between 22 and 57 psi. See several complete HFC R-134A pressure/temperature charts cited further below on this page; R134A temperature/pressure relationship: see the table above; R134A alternative name: 1,1,1,2-Tetrafluroethane or CH 2 FCF 3; R134A boiling point: −26.3 °C (−15.34 °F) at atmospheric pressure (sea level or 1 ATM).
