Related video about 410a Normal Operating Pressures : This is where our friend R-410A came into play. New machines from 2010 and onwards were banned from using R-22. Instead, they were outfitted with R-410A. If you would like to read more about R-410A refrigerant please have a look at our Puron fact sheet. R-410A PT Chart.The SC might be normal , but the normal head for a r410 system w/ a 68* ambient should be closer to 300psi and the normal suction press should be closer to 110psi w/70* IDB. Those p/t's sound more like r22. kdean1, buttwheat liked this post. As others have said it sounds like a TXV and maybe low on juice.Luckily, there is a pressure instrument that can detect whether or not your head pressure exceeds the normal range and is too high. Head pressure is okay as long as it isn't outside the normal range. ... What Determines High Head Pressure. A 410A system who have 400-418 PSIG on the high side, while the lower side is 120-130 PSI. If it is more ...It should be noted, however, the normal operating refrigerant temperature will never exceed 150°F. Based on the saturation properties of this refrigerant, the pressure would need to be over 1700 psi to reach 250°F during normal operation of the system. No VRV or VRF system will ever get close to this pressure.Good Subcooling Value for R-410A: Similar to superheat, the ideal subcooling value for R-410A can vary depending on factors like system design and operating conditions. However, a common target for R-410A systems is to achieve a subcooling value in the range of 8 to 15 degrees Fahrenheit (°F) or approximately 4.4 to 8.3 degrees Celsius (°C).These units use R-410A refrigerant which operates at 50 to 70% higher pressures than R-22.
