All air conditioners use an oil to keep the compressor lubricated during operation. R-22 air conditioners use mineral oil and R-410A systems use synthetic oil . The synthetic oil is generally more soluble with R-410A than mineral oil is with R-22.What does pressure do 410A need to be?
During air conditioning mode, the pressure on the vapor line of an R-410A system will be somewhere between 102 to 145 PSIG. If the system had R-22, the vapor pressure would be between 58 to 85 PSIG but these pressures will be dependent on the wet bulb temperature inside the building and the ambient temperature outside the building.Is 410A compatible with R22?
R410A runs at a higher pressure than R22 does, so a system designed for R22 cannot use R410A. If you put R410A into an R22 system, then the compressor and other components could rupture - completely ruining the system. Another difference between the two refrigerants is that R410A is able to absorb more heat than R22 refrigerant.What is the normal operating pressure for a 410A refrigerant?
If a new R-410A refrigerant bottle had a surrounding air temperature of 75°F, the pressure inside the bottle would be 217 PSIG. Likewise, an R-410A recovery bottle with a surrounding air temperature of 75°F should have an internal pressure of 217 PSIG.
