Depending on the equipment and operating conditions, viscosity is selected. There are several manufacturers producing lines of refrigeration oils for the 410 refrigerant: Mobil EAL Arctic 32.46, 68.100;, R-410A is a higher pressure and capacity refrigerant than R-22, requiring equipment and components specifically designed to accommodate the resulting higher system pressures and lower flow rates needed. Typical operating pressures of an R-410A system will be 50% to 60% higher than those in an R-22 system at comparable operating conditions., Here is a list of the pressure readings that are characteristic of an A/C compressor that is not blowing cold air into the cabin of your car: 250 PSI / 30 PSI = You have air somewhere in the system. 250 PSI / 50 PSI = The system is overcharged and the condenser is not cooling. Condenser may be blocked. 225 PSI / 80 PSI = It is likely that the ..., Jun 7, 2014 · 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 ..., 4 days ago · Let's get started and see what we can do.Most manufacturers recommend charging by super heat and subcoolimg rather than pressures alone,and will vary slightly by manufacturer but as a rule low side of about 110 and high side about 280at 70 degree ambient. This will of course increase as temp warms up.ON an 85 degree day,probably …, A normal blood pressure range, according to WebMD, occurs when the systolic number is 120 or below and the diastolic number is 80 or below. High and low blood pressure problems aff..., The warmer it is outside, the higher the pressure will be. For a general reference, you can check out this chart of R-134a system pressures. If you find you’ve got a low pressure on the low side of your system, then it’s most likely that you’ve got a leak as that is a common problem in automobile air conditioning systems.
