You are called in to service a R-410A unit which is low on charge. You know that it has been topped off before?
What is the question?
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.
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. It's your call. Links are provided.

What is the purpose of a csu dsu?
Known fully as a Channel Service Unit/Data Service Unit, a CSU/DSU is meant to function as a device that connects routers to a T1 line. The CSU works by connection to a telecom network and the DSU handles the interface with the Data Terminal Equipment, or DTE.

What is the question?
What needs to be done to retrofit your ac unit?
Depends on what you are retrofiting from- to? R-22 to R-410a or r-12 to r134a?
What is the 410a operating pressure?
The 410a operating pressure is 7.037 Barg or 102.036 psig.
Can you recover r-410a freon?
If you add 410A to a heat pump does it put out more heat or less?
What type of freon would be used for a lennox ac unit r111-r134a or something else?
It depends on what year the unit was built. Most AC units for your Home used R-22. A new freon 410A is used in the newer systems. There has been a slow switch over from about mid 2005 until now but the EPA has banned AC units from being built with R-22 now so any unit you buy today will have the 410A.
The minimum safety-relief pressure for a R-410A cylinder is .?
minimum pressure is 525 psig for R-410A
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.

What replaced Freon?
R-410a
Do you have to braze 410a?
Yes, its a requirement of all manufacturers, that i know of, to braze 410a connections with a brazing alloy containing a minimum of 15%
When was Clinical Trial Service Unit created?
Clinical Trial Service Unit was created in 1975.
