What refrigerant can be used to replace R22?

R-407c
The best replacement for R-22 Freon is usually R-407c. It has a very low loss in capacity (0 – 5%) relative to R-22 and is less expensive than many other R-22 replacement refrigerants.

What is the difference between R22 and R134a?

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. The water absorption of R134a is 20 times of R22, so the requirements of the dryer in the system is higher, in order to avoid the phenomenon of ice jam.

Can you put R1234yf in a R134a system?

It appears R1234yf oil is compatible with R134a (but not vice-versa), so shouldn’t be a problem there.

Can you mix 134A with R12?

R134a systems operate at higher discharge-side pressures than R12, which can cause compressor seals to leak. Bottom line, R134a simply doesn’t cool as well as R12. The advantage of ester oil is that it works with both R12 as well as R134a, so you can fill the system with it and then use either refrigerant.

Is R22 still used?

As of January 1, 2020, production and import of R22 refrigerant will be illegal in the United States. Of course, continued use of your air conditioner (AC) or heat pump system using R22 refrigerant is allowed.

Can you mix R22 with are 134a refrigerant?

R-22 systems are typically about 300 psi maximum. 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.

Can a are 22 compressor be replaced with r-134?

R-22 and R-134 use different oil, so R-134 is not a “drop-in” replacement for R-22. In addition, R-134 is in a different pressure/temperature ‘class’, and will not work in a system with a compressor designed for R-22.

What’s the difference between R22 and R134a air conditioners?

Here are some other issues: R134a has a lower thermal conductivity than R22, so an R134a system needs a larger heat exchanger. A system circulating R134a needs a drier, because of the propensity of the refrigerant to absorb water. R134a swells the rubber components in the refrigeration system and causes leaks.

Is the R-22 refrigerant still in the market?

After 2020, any air conditioning or heat pump system using R-22 that requires servicing will have to depend on potentially expensive R-22 stockpiles or reclaimed refrigerant. The new ban on R-22 won’t affect homeowners that want to continue to utilize their functioning R-22 air conditioning systems.
