Can you mix R12 and R22 refrigerants?
You can't mix refrigerants for serveral reasons. R12 and R22 are used to make R500 which operates at a much lower head pressure than R22 alone. In fact R500 was used some back in the old days as it was similar to R12, just operated at slightly higher suction pressure.
What is the difference between R12 and R22?
R12 and R22 are used to make R500 which operates at a much lower head pressure than R22 alone. In fact R500 was used some back in the old days as it was similar to R12, just operated at slightly higher suction pressure.
Can you mix R438A and R22?
Linde does not recommend mixing R438A and R22. Therefore the entire original R22 charge should be recovered without releasing any gas to the atmosphere. Also, what is compatible with r22? RS-44 is a direct drop-in replacement for R22 in ac applications in systems with a capillary as well as an expansion device.
What can I use instead of R22?
Also, what is compatible with r22? 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.
Are R12 and R22 compatible?
R12 and R22 do mix.Apr 23, 2020
What refrigerant can be mixed with R12?
R12 is compatible with mineral oil, and most R12 systems use this. R134a uses Polyalkylene Glycol (PAG) oil. One commonality both R134a and R12 share is that they are compatible with Polyol Ester Oil (POE).
What refrigerant can you mix with R22?
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.Oct 22, 2018
What's the difference between R12 and R22 refrigerant?
First of all R12 is the "older version" of freon that is no longer used. Also, it was used primarily in car air conditioning. As for R22, it is part of the new family of freon that supposedly hurts the ozone layer less than the ones before it (hence the reason why it was banned). R22 is one of the replacements for R12.
What happens if you mix 134a with R12?
Mixing R12 and R-134a refrigerants is illegal, and even if you previously bleed out the R12, the system has to be adjusted to use R-134a, or it will cause leaks, copper corrosion, and lack the lubrication required for optimal operation.Nov 26, 2021
What happens if you mix AC refrigerants?
What Happens to Your AC System if You Mix Refrigerants? Mixed refrigerants can cause increased system pressures and temperatures changing them for the worse. This can result in ineffective compressor cooling and possible compressor damage, ineffective cooling, and metering device malfunction.
What happens if you mix R22 with MO99?
Mixing refrigerants is never recommended. However, based on the similar operating conditions of Freon™ MO99 and R-22, system damange would not be expected.
Can I mix R22 with R290?
Because R290 has similar saturated pressure-temperature characteristics and volumetric refrigerating capacity as R22, is miscible with the oils typically used in R22 compressors, is relatively cheap and is reported to yield favourable efficiency, it is often deemed as a desirable option to use in existing R22 systems.Aug 21, 2016
Can you mix R22 with nu22?
Can Freon™ MO99™ or Freon™ NU-22B™ be mixed with R-22? No. There is no such thing as a “drop in” replacement for R-22. Mixing refrigerants is not recommended.
What happens if you put the wrong refrigerant in your car?
You cannot mix refrigerant types, and putting the wrong refrigerant in your car will cause damage to the air conditioning system! If you're not sure which kind of refrigerant your vehicle takes, DIY A/C charging may not be for you.
Can I add R134a to a R22 system?
R134a has a lower thermal conductivity than R22, so an R134a system needs a larger heat exchanger. R22 refrigerant and its HFC replacement R410A are totally incompatible. Your existing condensing unit and cooling coil are not suited to the new higher pressure refrigerant.Mar 17, 2020
Can you use r134 in place of R22?
However, units made after 2010 can use R22 alternatives such as R410A, R134A, R407C, and R407A. These refrigerants cool just as effectively as R22 without the ozone depleting features, and they have an acceptable Global Warming Potential (GWP).Apr 28, 2020

What is the difference between HCFC and R-22?
These refrigerants contain chlorine, fluorine, and carbon. HCFC, a “replacement” refrigerant used in place of R-22, is also made up of chlorine, fluorine, and carbon, but contains a hydrogen atom.
Can you optimize a R-22?
This means that you can’t optimize the system charge, which can lead to overheating and reduced system efficiency and lifetime. A loss of efficiency will occur. There may be an unpredictable and extreme change in efficiency as most R-22 refrigerants do not operate as efficiently as R-22 even when it’s not mixed.
Can you mix different refrigerant?
You’re wondering if you can mix different refrigerants for your air conditioning system. The short-long-only answer is no, never. There are many reasons why it’s impractical, illegal, and not economical for a homeowner to mix refrigerant types. CFC-type refrigerants like R-22 – the most popular in the United States by far – are a single type ...
Is it safe to mix R-22 refrigerant?
But always remember, the system has to be free of all other contaminants and refrigerants before using a replacement for R-22 or any other refrigerant. As you know , mixing refrigerants is not good for anyone. The customer’s system will suffer from lost efficiency and decreased longevity for the equipment.
Is R-22 still used in 2020?
According to the Environmental Protection Agency (EPA), in 2020, R-22 will no longer be produced or imported . After 2020, only recovered, recycled, or reclaimed supplies of R-22 will be available. Due to the EPA phasing out R-22, it’s important that you stay informed on how you should service, repair, or replace your air conditioning unit that uses the refrigerant.
Can refrigerant be reused?
If refrigerants aren’t mixed together, they can be reclaimed and reused. If they’re mixed together, the only option for the contractor is to turn the contaminated refrigerant over to a parts house at an additional cost. The parts house sends it to a company that incinerates the refrigerant, so it can never be reused.
When will R-22 be available for A/C?
As noted above, chemical manufacturers will no longer be able to produce, and companies will no longer be able to import, R-22 for use in new A/C equipment after 2010, but they can continue production and import of R-22 until 2020 for use in servicing existing equipment.".
How to get isopropyl alcohol out of a compressor?
Pour isopropyl alcohol into the lines ones at a time. Blow air through the lines afterwards using the blowgun. This pushes the contents out of the line at the compressor end. Use a bucket to catch the contents.
Is R12 banned in the US?
Rules governing changing from the former to the latter differ between countries. R12 and R22 are both now banned by the EPA in the United States. Other more environmentally friendly alternatives exist, but even those cannot be changed in air conditioners or other refrigeration units with R12 without a thorough cleaning of the unit. Advertisement.
Will R-22 be recycled?
According to the EPA, "After 2020, the servicing of R-22-based systems will rely solely on recycled or reclaimed refrigerants . It is expected that reclamation and recycling will ensure that existing supplies of R-22 will last longer and be available to service a greater number of systems.
Is R22 a good refrigerant?
R12 and R22 are two refrigerating agents for air conditioning units. Image Credit: Comstock/Comstock/Getty Images. R12 was once used in many air conditioning units as a refrigerant or cooling agent. However, it was found to be a very bad gas for the environment. But R22 is almost equally damaging.
When will R22 be obsolete?
The R22 phase out date means that after January 1, 2020, HVAC systems that use R22 will be obsolete. If the repair requires adding R22 refrigerant to the system, the only options will be reclaimed and previously-produced R22 refrigerant.
Can R438A be mixed with R22?
Linde does not recommend mixing R438A and R22. Therefore the entire original R22 charge should be recovered without releasing any gas to the atmosphere. Furthermore, what is compatible with r22?

Is R410A a good refrigerant?
To make a short story long, R410A and R22 are refrigerants. They are both good refrigerants and they both work, but they have to be charged in the system at different pressures. R410A is a higher pressure system and R22 is a lower pressure system. Click to see full answer.
