R22 low side pressure at 70 degrees

Liquid line temp 101 degrees and the suction was 49 degrees. The low subcooling and low suction pressure indicate low airflow. The somewhat low deltaT seems to contradict that. Could be a significant amount of air bypassing the coil based on your report, which would account for all of the numbers that you posted.

T/P chart says pressure is say R22 is 168 @ 90 degrees. How can the OP even have numbers as low as was reported? I would think the unit would have to be nearly empty of charge to have numbers this low.... as I understand it (studying for my 608 T2 exam, BTW ), if I have even a few ounces of R22 in a container at 90F, the pressure should be 168 ...R-134A Refrigerant Pressure Temperature Chart - R-134A is an inert gas also known as Tetrafluoroethane, ... 70: 69: 260: 149: 72: 71: 270: 152: ...

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).We would like to show you a description here but the site won't allow us.However, if it drops below 50 PSIG (~27 degrees F), it seems it will never get above 90 PSIG to close the switch without the compressor running. So, the switch would never close as the static pressure on the suction line would never get to 90 PSI on an R22 system, especially one whose compressor isn't running.

R-22 Refrigerant Temperature and Pressure Data Ambient Temperature in °F1 R22 Low Side Pressure2 95°F (35°C) 181.9 psig 110°F (43.3°C) 226.4 psig 150°F (65 ..., degree, in Mechanical Engineering. Both have vast experience in the field of Heating Ventilation and Air Conditioning. Aaron has worked on multiple design ... R22 Low And High Side Pressure Chart 3 3 people. This is possible because of the vast research the authors have done before starting this work. Advanced Cooling Technologies and Applications, Sodium is a mineral that is essential for human health.

Ask Your Own HVAC Question. ... I have a R22 system Low side pressure is very low when running ... Can one explain in regard to R22 what determines a good PSI on high and low on a 90 Degree day with the indoor temp 80 what determines these presures ..., T/P chart says pressure is say R22 is 168 @ 90 degrees. How can the OP even have numbers as low as was reported? I would think the unit would have to be nearly empty of charge to have numbers this low.... as I understand it (studying for my 608 T2 exam, BTW ), if I have even a few ounces of R22 in a container at 90F, the pressure should be 168 ...
