Suction pressure of an Air-Conditioner with R410A Refrigerants typically ranges between 115 Psig to 125 Psig when operated at an ambient temperature of 35 degC. The discharge pressure at this operating conditions hovers around 400 Psig. R-410A operates at pressures 50 to 70% higher than those of R-22. When to use refrigerant R-410A pressure ...'ve highlighted 117 PSIG in the chart above. It's a ballpark figure of where the suction pressure could be on an R-454B system. The P-T chart tells us that the suction saturation temperature (SST) for an R-410A system is 39.4°F at that pressure. R-32 is very close behind at 38.3°F. R-454B is a little higher at 44.6°F.Apr 25, 2017 · Turn the thermostat to cool and set the target temperature at least 10 degrees lower than the indoor temperature. Let the system operate for at least 10 minutes to let pressures equalize. Record the suction line pressure.

R410a suction pressure may be around 120psi, and R410a head pressure may be anywhere from 225psi to 350psi. Many conditions could apply here, there's absolutely 'no' set point pressure for 410a, r22, or anything else. ... Lots of low pressure systems, such as wine coolers and ...Realize that there may be some pressure drop on a 100′ line set, and there should be very little in a 10′ line set. Make some allowance according to the situation. If the system runs VERY low or VERY high suction pressure or superheat readings that are way out of range, it is very unlikely that adjusting the valve will remedy it.Head pressure 190.
