Photograph of a commercial air conditioning compressor charging chart … Definition of Air Conditioner High Side and Low Side Pressures …. R22 temperature/pressure relationship: see the table above; R22 alternative names: CHClF2 .
High side will generally be in a ballpark of 250–280 roughly but that depends on ambient temperatures, little lower on water cooled condenser. Low side pressure for ac is going to vary slightly depending on metering device, expansion valve, capillary ect and load/return air temperature.
Gas and Oil Home Heating Furnaces – R22 Guage Readings – What should the … How to read gauges IF EVERYTHING IS NORMAL. … The head (high side) pressure depends on the TEMPERATURE at which … If there is no condensation on the outdoor suction it is possible that you are low on refrigerant.
In my (2) R22-based HVAC systems, the low pressure side is 40 and 45 degrees Fahrenheit (F) while the high side is 110 and 115 degrees.
SUBJECT: TEMPERATURE – PRESSURE CHART FOR. FYI #289 9/17/2009. R-22, R-410A, R-407C, R-134A & R-404A REFRIGERANTS. ADVANTAGE .
The low-pressure side, when connected to the gauge, should read less than 100 psi. … For this reason, charts are published in manufacturer manuals or in local … If the pressure reading is too high, the unit may have been overcharged in the .
generally it should be around 225 on the high side and near 70 on the low. What is the condition of the outdoor coil? Is it clean? It sounds like it .
The low side is 65 psi and the high side is 240 psi. Would this indicate I need to add a pound or two of R22 or is the compressor getting weak?
