Jan 27, 2021 · This would typically cause a low suction pressure, and a low superheat. In heat mode, a dirty air filter causes low airflow across the condenser. This can cause extremely high head pressure. In heat mode, a dirty outdoor coil can cause a low suction pressure. As an example, Trane includes a pressure curve chart with many heat pump condensing units.
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.Low side pressure reading be on an r22 home unit [ 1 Answers ] I have a Goodman natural gas pac unit 13 seer , what should the pressure gauges be reading on the low side mine is currently running around 70 to 72 which reflects to 33 to 34 degree coil temp is this about right.R22 Pressure-Temperature Chart-49-45: 1-17.2 51: 10.6 101: ... 17.2 70 171 341.6 ...
