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).Nov 13, 2020
What is the normal suction and discharge pressure for R22?
For example, a high-efficiency condensing unit using R-22 typically operates with a suction pressuresuction pressureIn refrigeration and air conditioning systems, the suction pressure' (also called the low-side pressure) is the intake pressure generated by the system compressor while operating. ... As the cell absorbs more and more water its Turgor Pressure increases and Osmotic Pressure decreases.https://en.wikipedia.org › wiki › Suction_pressureSuction pressure - Wikipedia of about 68 psi and a discharge pressure of about 250 psi at an outdoor temperature of 95°F.
What is a high head pressure for R22?
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.Nov 13, 2020
What are normal operating pressures for R-22?
For example, a high-efficiency condensing unit using R-22 typically operates with a suction pressuresuction pressureIn refrigeration and air conditioning systems, the suction pressure' (also called the low-side pressure) is the intake pressure generated by the system compressor while operating. ...

What should R-22 pressures be at 85 degrees?
R22 pressure at 85 degrees shows a vapor pressure of around 170 psi at the sea level.Nov 13, 2020
What should R-22 pressures be at 75 degrees?
IF the return temperature is 75 the evaporating temperature of the R-22 should be between (75-40=35) and (75-35=40). THE LOW SIDE NEEDLE SHOULD POINT BETWEEN 35 AND 40 DEGREES (in the green ring of numbers) FOR R-22 AND THE PRESSURE IS READ WHERE THE NEEDLE POINTS ON THE BLACK RING OF NUMBERS FOR PRESSURE.Jul 3, 2003
