Sight glass is clear (liquid refrigerant stream) It is difficult to appear bubbles in the sight glass even if water is splashed to condenser coil. The substitute that we used for R-12 was the new HFC called R-134a. It was later found that R-134a had a very high Global Warming Potential, or GWP, number. GWP is a measurement of Greenhouse Gases and their effect on Global Warming. A lower GWP alternative to R-134a had to be found and thus we have the new 1234yf. How is 1234yf different from ...

If the pressure differential is significantly lower or higher than the expected range, it may indicate a restriction in the system, an incorrect refrigerant charge, or an issue with the compressor. wsyr channel 9 news 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 ...The pressure for an ordinarily operating R134a is between 22 and 57 pounds per square inch (PSI). Remember, there are two sides to the chart; we have the low and the high. Therefore in a normal R134a, the low-pressure side is 90 degrees or less, and the PSI should be close to 30.The ideal pressure for R134A depends on the ambient temperature. For example, at an ambient temperature of 72 degrees Fahrenheit, the optimal low side pressure should be about 26 psi and the high side pressure should be about 225 psi. However, these numbers can vary depending on your specific vehicle model.
