Can you mix any Freon with R22? 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 freon can I 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.
Can you put 134a in a R22 system? Using R134a in Systems Designed for R22
For one, the cooling capacity of R134a is only 60 percent that of R22, so the system condenser has to work overtime to produce the same amount of cooling. R134a has a lower thermal conductivity than R22, so an R134a system needs a larger heat exchanger.
Is 410A Freon compatible with R22? No, you cannot. 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.
If you add R-22 to an R-134a system, you will not get close to the rated cooling capacity of the A/C system. In conclusion, do not mix R-22 with R-134a refrigerants, you will ruin the charge, and possibly seriously damage or destroy your A/C system. NEVER mix refrigerants.
Mixing refrigerants is never recommended. However, based on the similar operating conditions of Freon™ MO99 and R-22, system damange would not be expected.
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.
Due to the destructive effects of the compositions of refrigerants on the environment, the EPA has banned the use of certain refrigerants altogether. These banned refrigerants were to be replaced with new ones, and mixing refrigerants became totally illegal.
R22 Freon Cost Per Pound
R22 Freon costs $90 to $150 per pound installed or $13 to $21 per pound wholesale.
In short, the answer is, “No!” Automotive refrigerants are volatile compounds that can have a negative effect on the environment. Combining them can have adverse effects, and cause damage to your car’s A/C system.
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.
Mixing R22 with R407C
According to the 609 EPA rule, mixing refrigerants is illegal and anybody caught doing so will be heavily fined.
Improved efficiency: R410A is able to absorb and release heat better than R22, making it more energy efficient. Plus, because it’s more fluid in temperature changing abilities, it does a better job heating or cooling your house quickly.
The cost to convert a central air conditioner from R-22 to R-410A can range anywhere from $2,000 to over $4,500 in the New Jersey area. The bottom line? If your AC unit is 8+ years old, it’s usually not worth the cost to convert and you should just replace the entire R-22 unit with an R-410A unit.
If that’s so, then what R22 there is in the system can never evaporate under the higher suction pressure of R410a. It will just flood back to reduce the compressor life and will greatly reduce the system capacity. Do I have an answer? No, but I suspect that mixing the two refrigerants is a terrible idea.
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.
Hydrochlorofluorocarbons, or HCFCs, are chemicals that are mainly used as refrigerants. Unfortunately, releases of HCFCs deplete the Earth’s protective ozone layer and contribute to climate change. R-22 is an HCFC refrigerant that is often used in air-conditioning equipment.
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.
Of all the “no oil change” replacement refrigerants, Freon™ MO99™ offers the closest performance match to R-22. It facilitates easy retrofitting in which the technician simply recovers the R-22, replaces critical seals, charges the Freon™ MO99™ refrigerant, and monitors for leaks.
This substance is not flammable in air at temperatures up to 100 deg. C (212 deg. F) at atmospheric pressure. However, mixtures of this substance with high concentrations of air at elevated pressure and/or temperature can become combustible in the presence of an ignition source.
There are some R290-based mixtures designed as a virtually drop-in replacement for R22. Not all R290, of course, but they do work in R22 systems. At least one of those (Enviro-Safe 22a) even guarantees that it will not damage equipment when used correctly.
In the case of the first category — intentional mixing — an obvious suggestion is to avoid mixing different types of refrigerant in the same recovery cylinder. Unintentional mixing can certainly occur when systems or previously filled recovery cylinders are not labeled correctly.
The amount of cooling for your system can be estimated in the range of 2 to 4 pounds per ton. The 3-ton AC or Heat Pump with a 35 foot lineset will need a total of about 12 pounds of refrigerant.
R22 refrigerant has been used for years in central air conditioners, heat pumps, mini-splits, car AC systems, and other refrigeration equipment. It’s the key to absorbing and removing heat from a space.
The specific volume of R134a is 1.47 times than R22, and the latent heat of evaporation is small, so the cooling capacity of R134a units is only 60% of R22 units. R134a is more powerful than R22 on the swelling of rubber, and the leakage rate is higher in the actual operation.
