How do I know what type of freon I need?

How do I know what type of freon I need?

To know which type of refrigerant your air conditioner uses, take a look at the label on the compressor unit outside. It’ll clearly tell you which type of refrigerant the unit uses. The newer type is R-410A, and the older type that I’ve been talking about is R-22, also identified as HCFC-22.

Can you replace R22 with R134a?

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.

What happens if you put R12 in a R134a system?

R134a systems operate at higher discharge-side pressures than R12, which can cause compressor seals to leak.

How do I change from R12 to 134a?

How to Convert an R12 to the R134a System

1. Discard any R12 refrigerant still in the system by taking your vehicle to a licensed air-conditioning professional.
2. Open the engine compartment of your vehicle.
3. Push the high side retrofit R134a fitting over the old fitting and use a wrench to tighten it.

Is R12 colder than R134a?

R12 was just more robust and blew colder. R134A takes a while to warm up, and it’s harder to cool as the ambient temperature got higher. You can still buy R12, but be prepared to pay a premium.

Is it legal to buy R12 refrigerant?

Yes you can legally sell the R12 you personally own. The catch is that only a licensed technician can handle the R12, meaning purge and charge a system, but that is up to the individual purchasing the R12 if they want to follow the law by finding a technician or not.

Can you still recharge R12?

No you can not recharge an AC system equipped with R-12 unless you are a licensed technician. You can convert your AC system to R-134 yourself, once the R-12 is dealt with correctly.

Why is R134a being phased out?

Why is 134a Being Phased Out? Unlike the CFCs and HCFCs of the past 134a does not contain Chlorine and does not damage the O-Zone layer. The worry with 134a is it’s Global Warming Potential, or GWP. GWP is a relative measure of how much heat a greenhouse gas traps in the atmosphere.

Why is R134a banned?

Current HFC refrigerants (R134a and R404a) have a high Global Warming Potential (GWP) that is harmful to the environment. The GWP expresses the contribution to the greenhouse effect of a greenhouse gas compared to Co2 which is considered with a potential 1.

Can I replace R404A with R134a?

For cold rooms and other small to medium commercial refrigeration applications, R448A and R449A and R452A or R134a are excellent alternatives to R404A, with from 50 to 65% reduction in GWP. R513A and R134a are also good affordable alternative for MBP systems with a greater refrigerant charge.

What’s the difference between 134a and 404a?

R134 is designed for what is called high/medium temp jobs such as chillers R404 is for lower temp work ie freezers.

What refrigerant is replacing 404a?

R-449A is an HFO-based refrigerant blend designed to replace R-404A in stationary refrigeration applications. It combines excellent cooling performance and energy efficiencies with a low-GWP value of 1,397.

What is replacing R404A?

Summary. R407A is a HFC blend, used as a replacement for R22 and R404A in low and medium temperature supermarket applications. Due to its moderate Global Warming Potential (GWP) it is also considered as an interim replacement for R404A and R507 in existing and new applications.

What is the difference between 407A and 407C?

Freon™ 407C and Freon™ 407A are non-ozone depleting blends of three hydrofluorocarbon (HFC) refrigerants. Freon™ 407C exhibits performance characteristics similar to R-22. Because Freon™ 407C and Freon™ 407A are mixtures of HFCs, they have zero ozone depletion potential.

Can I replace 404A with 407C?

The changeover from R404A to R407A is said to relatively easy and in many cases, the original oil can be used. R407A, like other gases in the R407 series, is a zeotrope and must be charged in the liquid phase to prevent fractionation. The glide requires a minor adjustment to the expansion device.
