However, this rule of thumb (obviously) does not work on an R-410A system. A more applicable guideline is 20˚-25˚ suction saturation below outdoor ambient. This means if it is 50˚ outside, the suction saturation ...

Thank you for asking about your Volkswagen. On a 95 degree day, the low side should be reading at or around 35 PSI, so it sounds like the A/C is in normal working condition. Try checking the high-side PSI to see if it is abnormal. The high-side PSI reading on a 95 degree day should be about 240 PSI.

Then take the suction pressure and convert it to temperature on a temperature/pressure chart. Subtract the two numbers to get superheat. For example, 68 psi suction pressure on a R-22 system converts to 40 ° F. Let's say the suction line temperature is 50 ° F. Subtracting the two numbers gives us 10 ° F of superheat.Make your job easier with our handy refrigerant pressure temperature HVAC app with R-421A included.Consult your PT chart for corresponding pressure. My R22 walkins maintain 34 to 38 degrees with a delta of around 10 to 15 degrees. Hope this helps. 48-50psi is about right, like anything else, clear the sight glass, check superheat and supcooling.

According to the R-22 PT chart, this is equal to about 54°F. With the thermometer, we measured the saturated R-22 temperature of 45°F. Here is how we can calculate the R-22 superheat in this system: Superheat (R-22) = 54°F - 45°F = 9°F. The superheat calculator also gives us 9°F superheat for R-22 refrigerant.80 degree day r404a pressures on a 90 degree day r404a pressures on a 100 degree day r404a pt chart pdf printable pdf for on site use related posts 404a pressure temperature chart www.hornliang.com.tw doesn't just offer Systems Analysis And Design Elias M Awad; it fosters a community of readers.The pressure cooker is a must-have kitchen appliance these days.

The superheat chart includes target AC superheat for 55°F to 128°F outdoor temperature (DB temperature) and for 50°F to 76°F indoor evaporator temperature (WB temperature).1. Attach your manifold gauge set to the high and low side ports and read the low and high-pressure gauges. They should be the same. 2. Measure ambient air temperature at the vehicle and under the hood WITH A THERMOMETER (do not use weather service temperatures). The static pressure correlates to the temperature of the AC components under the hood, not outside in front of the vehicle.*Red Italics Indicate Inches of Mercury Below Atmospheric Pressure Saturation Pressure-Temperature Data for R407C (psig)*That's with a Fahrenheit of 70-74 degrees Fahrenheit as the ambient temperature. Low and high side pressures should increase as the ambient temperature rises. The high-side pressure on a fully operating system will be around twice the ambient temperature + 50 PSI. So on a 90°F day, twice 90 = 180, plus 50 equals 230 PSI.Using the formulas provided: Condensing Temperature = 35°C + 10°C = 45°C. Evaporation Temperature = 27°C - 20°C = 7°C. These calculations serve as rough estimates. To ascertain the operational pressures of the compressor: For R22 refrigerant: High pressure is approximately 1.75 MPa. Low pressure is approximately 0.6 MPa.Enter the air temperature as 95 °F (35 °C). The tool has an inbuilt temperature conversion option that allows you to input the temperature in other units. Type the dew point temperature as 70 °F (~21.1 °C). The RH calculator will display the relative humidity as 44.48%. You can also use this tool to calculate air temperature and dew point. ….
