R22 low side pressure at 70 degrees.
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 ...
I borrowed some gauges and got readings on the high side of 125 psi and the low pressure went up as high as 95 after 15-20 minutes. I shut the truck off then. I also noticed the high pressure line icing up from the firewall to about halfway forward upon which it was cool and sweaty there. ...

c. Close the Service Valve Before Releasing Pressure. You can use a hex key or a wrench to close the service valve on the high-pressure side but don't close it entirely. d. Activate the Compressor, Then Release the Pressure. Use a jumper to activate the compressor instead of starting the car to release the pressure.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 ... 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). See this chart and go to the 70F line. That line says that at 135 psia (121 psig) 75 lbs of liquid volume will convert to .4027 lbs (6.4 oz) of vapor at the same volume. So even if a 30 lbs cylinder was capable of holding 75 lbs of liquid, the vapor in that cylinder would only be 6.4 ounces, and that is at 121 psig.Can't raise low side pressure above 50psi. The evaporator coil of my 15 year old Rheem AC system has had a slow leak for the last few years. So I've been adding app. 7lbs of R22 at the beginning of every summer.

While the concept of using R-290 as a refrigerant had been around for over a century it was rarely used due to the flammability risk. Over the years though technology has improved and the need for an environmentally refrigerant has surfaced.
Step 12. Compare the super-heat reading to the gauge's psi reading. If the super-heat reading is more than 20 degrees above the P/T chart's reading, then add R-22 until the super-heating reading reaches the optimal range -- between 8- and 18-degree super-heat, depending on the environmental conditions. Many technicians charge the system until ...An R12 system should have a minimum of 60 psi to avoid freezing. 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.The low-side should be near 30 PSI at 90 degrees Fahrenheit or less. Pressure that is too much lower or higher shows there is a problem. ... Low Side High Side; 70° ... at times it can fluctuate from 0 to -3 psig.
