At a given outdoor ambient, indoor wetbulb and dry bulb, the suction and discharge pressures should intersect on a graph at specific temp readings along a curve on the graph. Also, as Houston said, there should be a desired subcooling reading at the outdoor unit.Pressure-Temp Chart-40-35-30-25-20-15-10-5 0 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 95 100 105 110 115 120 125 130 135 140 145 150 11.6 14.9 18.5 22.5 26.9 31.7 36.8 42.5 48.6 55.2 62.3 70.0 78.3 87.3 96.8 107 118 130 142 155 170 185 201 217 235 254 274 295 317 340 365 391 418 446 476 507 539 573 608 Physical Properties of ...410a ductless mini split operating pressures. I know that you should rarely put gauges on a ductless mini split, and that you should dump the charge and just weigh it in. I have heard that there are spec sheets that will give you "normal operating pressures" based on indoor and outdoor conditions. This would come in handy when servicing systems ...On a 65 degree day. Web on a 50 degree day. Typical low pressure or suction side pressure for r410a is about 120 psi, varying by. Web a refrigerant temperature pressure reference chart shows pressures at various temperatures for r22, r134a, r407c, r404a, r410a, r507a. Web enter the temperature in either f or c degrees and the returned result is.of an R-410A system.! CAUTION 7. If suction-line filter drier was installed for system clean up, operate system for 10 hr. Monitor pressure drop across drier. If pressure drop exceeds 3 psig, replace suction-line and liquid-line filter driers. Be sure to purge system with dry nitrogen and evacuate when replacing filter driers. Continue to monitor.
