In the example of an R-410A packaged unit with a surrounding air temperature of 70°F, the pressure on both the high and low-pressure side of the system will be 201 PSIG.An R-22 evaporator running at 40F saturation temperature will have a corresponding pressure of 68.5 psig. Should the suction pressure drop below 57 psig, the coil temperature will drop below 32F causing moisture in the air to freeze on it (see Figure 4) causing no end of trouble. A R-410A evaporator running below 100 psig will freeze-up just ...

The charts start at the low end (-49°F) and tell you the pressures all the way to the high end (150°F). Example: What is the pressure of 134A freon at 85°F? You just chart the chart (found below) and you will see that at 85°F, the pressure of R134A is 95.2 psig (pounds per square inch gauge). Measuring the pressure of R134A refrigerant on a ...
R422D, also known as Freon MO29, is an R22 retrofit refrigerant comprised of R125 (65.1%), R134a (31.5%), and R600a (3.4%). It has a low boiling point of -44.7°C (-48.5°F) at 1 atmospheric pressure. That’s why is used in low-temp applications such as air conditioners and cars. Here is what you can use this R422D pressure temperature chart for: Do you find yourself constantly frustrated with low water pressure in your home? Whether it’s a weak shower, slow-filling toilet, or inadequate water flow in your kitchen sink, low...In most cases, the evaporator temperature (boiling temperature or suction saturation temperature/SST) is about 35 degrees below the indoor return temperature. So, if the indoor return temperature is 75 degrees, then you would get the typical rule-of-thumb 40-degree evaporator coil. However, the difference will vary a bit if you're running a ...TEMPERATURE - PRESSURE CHART FOR R-22, R-410A, R-407C, R-134A & R-404A REFRIGERANTS FYI #289 9/17/2009. updated 10/10/2012.

The low-pressure side, when connected to the gauge, should read less than 100 psi. PSI is the common measurement for pressure used in terms of pounds per square inch. By the time the refrigerant reaches these lines it has lost most of its heat and has collapsed into a liquid state, taking up less volume. This leads to a low-pressure environment ...Been hearing different stories about charging methods on a 35-40 degree day.
