When conducting repairs or diagnostics on a commercial cooler or freezer with R404a refrigerant, checking the pressure is key. However, in order to know the proper pressure, you also need to identify the correct corresponding temperature. The chart below helps you know what pressure R404a should run at. R404a Refrigerant Pressure Chart3. Compare the pressure readings to the pressure-temperature chart below. R-134a Static Temperature pressure chart. WARNING: Ambient temp is the temperature at the vehicle under the hood, NOT THE WEATHER SERVICE. R-1234yf Static Temperature Pressure Chart. What static pressures actually means.The analyzer (models vary) displays R-134a if the purity is better than 98 percent by weight. The unit displays FAIL if R-134a gas has not been identified or if it is not at least 98 percent pure. If the detected gas contains a hydrocarbon (flammable material), the unit sounds an alarm and displays HC.

Our Pressure Temperature Chart for the selected refrigerant is available for quick access; just use the button labeled (P/T). Use the refrigerant drop down for access to over 100 refrigerants. Plus and minus buttons add and subtract values in intervals of 1 to their related input fields.Then look at the pressure temperature chart of the refrigerant and there is your answer. 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 ... biglot credit card logintiny homes for sale myrtle beachpredator ghost 212cc kart racing engine accessory kit Pressure values should be very nearly equal on both LP and HP gauges. The actual static pressure will depend on the ambient temperature. To ensure it is on the right level, refer to a static pressures table applicable for R134A refrigerant (N.B. not shown on this poster).R-134a Pressure & Temperature Chart. Knowing the pressure and the temperatures associated to the machine you are working on is essential to being able to diagnose any possible issues.
