Why are there more safety precautions with r410a than with other popular refrigerants like r22 and r404a?
The pressure of R-410A is significantly higher than other refrigerants R-22 and R-404A. This does not mean that R-410A, or equipment containing R-410A is unsafe. It does mean that technicians must use AC equipment; cylinders and service tools have been re-engineered to handle these higher pressures.
Do you have to flush a r-22 when changing to a 410a?
You cannot charge s R22 system with R410A. You need to replace the Compressor, evaporator coil and check the piping sizes for R410. Also the oils have to be replaced. Vinay
Can you fill 410a freon into R22 system?
You could, if you don't mind destroying the refrigeration system. Different types of refrigerants operate at different system pressures, and also transport different compressor lubricants through the system.
Can you use new freon in r22 systems?
no. it is not a good idea. new hfc refrigerants require a different type of oil than the R22 units. the new refrigerants typically run at higher pressures than the R22 units.
What is the replacement for r22?
Several refrigerants are out with similar properties to R-22. Lately, the most notable one is R-410A, though it`s properties are not so close to 22 it is getting a lot of traction as the long term replacement. Another is 407C, but it never gained the popularity that 410A has. Probably because it is a blend and will fractionate. There is no drop in replacement for 22 that I am aware of and if there is it is not widely promoted or used.
What kind of Freon does a home air conditioner use?
Most home systems use R-22 refrigerant. R-410a, known as PURON, is also an increasingly used refrigerant. If you see a pink sticker on the outdoor unit, it will say on the tag with the model and serial numbers r22 or 410a. "Freon" is a trademark of DuPont, and is NOT the real name of refrigerant. "Freon" was R12 and is no longer made.
Can you use a condensor designed for R22 with an evaporator designed for R410A?
It depends on what you want to do with the sytem. If it is and older condensor contact the supplier and ask for specifications on what the condensor does in 410A. It only depends on the different pressures in the system en the condensoing capacity at R410A.
Which freon will leak from a smaller hole R-22 or R-410A?
The R-22 (chlorodifluoromethane), will leak from a smaller hole than R-410A will. Sort of. Now that we've answered the question, it's time to state that R-410A is an azeotropic mixture of difluoromethane and pentafluoroethane. And the difluoromethane component of the mixture is a smaller molecule than chlorodifluoromethane, which is what R-22 is. But the pentafluoroethane is a larger molecule than the chlorodifluoromethane (R-22). If molecular size is the sole determinate as to which "stuff" can get out, part of the R-410A can get out a smaller hole than the R-22, but all of the R-22 can get out through the "right sized hole" because it is smaller than a constituent of the R-410A.

What is the 410a operating pressure?
The 410a operating pressure is 7.037 Barg or 102.036 psig.
What refrigerant is now used in home central ac units?
Most new equipment is built for and charged with R410a, a refrigerant with much higher pressures than the R22 used for decades, R22 units are still available, dry charged however, you must fill them with R22 onsite. This is how new R22 compatible equipments being sold still.
Can you recover r-410a freon?
If you add 410A to a heat pump does it put out more heat or less?
The minimum safety-relief pressure for a R-410A cylinder is .?
minimum pressure is 525 psig for R-410A
