Are R134a and R22 compatible?

Using R134a in Systems Designed for R22 If you have a home or auto air conditioner designed to work with R22 refrigerant and the system needs a recharge, a number of issues prevent the direct substitution of R134a. R134a has a lower thermal conductivity than R22, so an R134a system needs a larger heat exchanger.

Can you mix R22 with any other refrigerant?

Mixing R22 with R407C or any other refrigerant. According to the 609 EPA rule, mixing refrigerants is illegal and anybody caught doing so will be heavily fined. If your system is running on R22 most likely is using mineral oil to lubricate the compressor.

What kind of freon can you mix with R22?

R-407C
The most commonly mixed refrigerants in the field are the replacements for R-22 — R-427A, R-438A, R-422D, and R-407C — which are often combined with the remaining R-22 in the system, said Maiorana.

What refrigerant can be mixed with R134a?

There are three refrigerants that can be used to replace R-134a: R-1234yf, R-152a and R-744. More on these replacements later.

Can you use R134a in a R410A system?

The United States explicitly prohibit the use of R410A and R134a refrigerant.

Can I use R134a in my home AC?

While used mostly in cars, only one home air conditioner has been made, as of November 2010, that uses R134a as a standard. As of 2010, new home air conditioners that are produced must use a refrigerant that does not deplete the ozone. R134a is a hydrofluorocarbon that does not cause environmental harm.

Can I mix R410A with R22?

R-22 and R-410a are both refrigerants, true. They can both be used in air conditioners or heat pumps to cool your home during summer. You should never, ever try to mix them in the same system, or use them in a system not rated specifically for that kind of refrigerant.

What happens if you mix R12 and R134a refrigerants?

R134a systems work at higher discharge-side pressures than R12 systems, which could lead to compressor seals leaks. Additionally, since R134a is composed of much smaller molecules, it has a greater chance of leaking from an R12 system.

Can you mix 12a with R134a?

You should NEVER mix refrigerants or mix incompatible oils. Putting a 12a refrigerant into a system that had R134a, without a complete and thorough flush of ALL components, and purge of the flush chemical, is called CONTAMINATION.

What is a direct replacement for R22?

RS-44 (R424A) RS-44 is a direct drop-in replacement for R22 in ac applications in systems with a capillary as well as an expansion device. There is no need to change the lubricant since, as with all the RS series of refrigerants, RS-44 is compatible with mineral, alkyl benzene and POE oils.

Where to buy r22a refrigerant?

If you will be buying just one or two cylinders of R22 refrigerant than I would recommend shopping online through E-Commerce websites. There are numerous websites out there to choose from but if I was to pick the best one out there today for one off refrigerant purchases I would choose E-Bay.

Is R134a corrosive?

R134a is not corrosive on standard steel, aluminum and copper samples. R134a is not flammable at ambient temperatures and atmospheric pressures. However R134a systems should not be pressure tested with air, because mixtures of air and R134a have been shown to be dangerous.

What is your – 22 refrigerant?

R22 refrigerant is one of the most commonly used refrigerants in the air conditioning systems. R22 is the short name for the halocarbon compound CHClF2 (monochlorodifluoromethane), which is used as the refrigerant. R stands for the refrigerant.
