Based on NOAA records, the year 2019 holds the record for the most 90 °F days in Atlanta history. There were 91 days with a high temperature of at least 90 degrees that year. How many so far this year (2024)? It has not reached 90 degrees Fahrenheit in Atlanta so far in 2024. As of May 19, the highest temperature this year is 87 °F.The same as R22, due to useful pressure-temperature properties, R407c is used in air conditioning systems, cars, and refrigeration units. ... From the PT chart, we can read that the pressure of liquid 407c on a 90-degree day is 194.1 psig. Similarly, we can see that the vapor pressure of 407c on a 90-degree is 166.7 psig.R-407C is a zeotropic blend of R-32 (Difluromethane), R-125, and R-134a (Tetrafluoroethane). It is not a drop in replacement on R-22 machines. If you wish to use this product you will need to vacate all of the old R-22 out of the system. This is due to the R-22 systems using mineral oil and this HFC blend using POE oil.R22 gauge pressure is 10.9 bar or 158.2 psi. High side pressure typically varies by equipment and metering controls. Low pressure or suction side typically varies by equipment. Low-pressure refrigerant turns on the carrier HVACR at 50 psi (R22 pressure at 30 degrees) and closes at 100 psi (R22 pressure at 85 degrees).The term gauge signifies that the pressure has been read from a gauge that actually measures the difference between the pressure of the fluid or gas and the pressure of the atmosphere. Psig is equal to psis at sea level (14.7 psi). Psig is equal to psia – 14.7 at sea level. Psia is absolute pressure, which means it is gauge pressure + 14.7 psi.If the low side temp was 60 degrees with the unit running at least 5 mins and the pressure is still at 70psi like it was the other day then your system is a bit low on refrigerant. This gives you a superheat of 19 degrees. On a 90 plus degree day you would like to see that superheat down around 8-10.90 Day Limited Warranty. Fitting Type: Adapter. Compare.

Best Answer. 265 PSI which equals 120 Degrees Fahrenheit, basically you add about 30 ...One key difference between R22 and 407C is their chemical composition. R22 contains chlorine, while 407C does not. This makes 407C a more environmentally friendly option, as it does not contribute to ozone depletion. Another difference is their boiling points. R22 has a boiling point of -41.5 °C, while 407C has a boiling point of -51.7 °C.The most common pressure in a r-22 charge domestic air conditioning systemon an 80 degree day would be?
