If the outdoor temperature is 70°F, a refrigerant bottle outside would have a pressure of roughly 201 PSIG. If the outdoor temperature is 110°F, a refrigerant bottle outside would have a pressure of roughly 366 PSIG.Jun 24, 2020
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
What is the saturation temperature for R-22?
R-22 system. Pressure as measured at the evaporator = 70 psi. The corresponding temperature on the P-T chart for 70 psi = 41F (saturation temperature) The refrigerant tubing's (coming from the evaporator) temperature is measured at the condensing unit at 55F.Feb 4, 2013

What temperature should R22?
This temperature should be about 35 to 40 degrees F below the Return Air temperature. IF the return temperature is 75 the evaporating temperature of the R-22 should be between (75-40=35) and (75-35=40).Jul 3, 2003

What should R22 pressures be on a 70 degree day?
If the outdoor temperature is 70°F, a refrigerant bottle outside would have a pressure of roughly 201 PSIG. If the outdoor temperature is 110°F, a refrigerant bottle outside would have a pressure of roughly 366 PSIG.Jun 24, 2020
What temperature R22 evaporates?
R22 is particularly interesting as it evaporates at -42°C at atmospheric pressure (compared with 100°C for water, 35°C for ether or 300°C for cooking oil). Because of its low evaporating temperature, R22 allows us to obtain a temperature of less than 0°C quite easily in the freezer of our fridge.
