for me if you add how many hindu arabic you write it can be in number on roman numerals,
V = 1/3πh ( R12 + R22 + R1R2 )where π is 3.14159265..., and R1, R2 are the radii of the two bases.
Yes the ancient Romans were able to add, subtract, divide and multiply They also had their own numeracy system known today as Roman numerals
No
NO ! and Why?
the things that must be considered when charging the system with R22; R404;R134;R507;R406
No, R22 is for refrigerators and home AC. It runs at a different pressure and you can't use one for the other.
No R134a is used only the cars, and R22 is only used for home central ac system. If you would like more information about R134a you can log on to www.idqusa.com.
No the whole system need to be evacuated of the r22 before you put r22a in the system. It's against the law to mix 2 different freons together and also dangerous.
The simple answer is that an R12 system wasn't designed for R22. There are different pressures reached, there are different compressor oils used, and R22 may not even be compatible with a compressor designed for R12. Changing an R12 system to R22 could be done, but it would require extensive conversion, and would still be undesirable - R22 is being phased out, largely because it's a carcinogen and because of the harsh environmental effects.
Not unless you like the idea of destroying your AC system.
Absolutely not ... R410 operates at much higher pressures than R22, and mixing would do nothing but contaminate both refrigerants (and possibly mess up your system)
Envirosafe sells R22a, a propane based freon that they claim is compatible with R22 systems, but to add this to your system legally you have to first have your system evacuated of reg. freon 22 by a recovery sytem, it is against federal law to release it into the atmosphere as well as mixing different types of freon. The good news is that it costs less than R22, they claim it is more efficient than R22 and you don't need a license to buy it. Although you seem to know what you are talking about just one question what is the difference in reg. FREON and R-22?
Wal-Mart do not have r22 freon, this is a false ad.
Yes
