There are three replacement refrigerant options for R12 systems:
R134a, R401a, R401b
. R134a is regarded, by manufacturers and adherents to the Montreal Protocols alike, as the best replacement refrigerant.
Is R12 and R134a compatible?
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.
What refrigerant is a drop in replacement for R12?
RS-24
is a non flammable blend of HFC 134a, HFC 125, butane and isopentane which has a zero ODP and is also compatible with both traditional and synthetic lubricants so that a retrofit is not required. RS-24 is a “Drop-in” alternative for R12 which also provides a long term solution at the same time.
What happens if you mix 134a with R12?
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 put R22 in a R12 system?
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.
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.
How do I switch from R12 to R134a?
- Discard any R12 refrigerant still in the system by taking your vehicle to a licensed air-conditioning professional. …
- Open the engine compartment of your vehicle. …
- Push the high side retrofit R134a fitting over the old fitting and use a wrench to tighten it.
Is there a direct replacement for R12?
The best replacement for R12 is considered to be
R-134a
. The chemical name of R134a is tetrafluoroethane and it chemical formula is CF3CH2F. It is a hydrofluorocarbon (HFC) and has zero ozone depletion causing potential and very low greenhouse effect.
What is the replacement freon for R22?
R22 is being replaced by
R-410A
, a safer material which is the current, compliant standard refrigerant in air conditioning equipment.
Is Freon 12 the same as R12?
Refrigerant
R12
or Freon 12 is said to be the most widely used of all the refrigerants being used for different applications. The chemical name of refrigerant R12 is dichlorodifluoromethane and its chemical formula is CCl2F2.
How do you tell if you have R12 or 134a?
when new,
it was r12
. if it’s been changed over,look at the hi and low side ports. see if 134a adapters are screwed down on top of the r12 fitting ports. they will be larger.
Can you mix 12a with R12?
And while you can mix 12a in with existing R-
12 without issue
, I personally recommend that the system be flushed, vacuumed, and re-oiled anyway, as the head pressure of 12a is lower than R-12, thus your system will operate much more efficiently with a single product in it.
How much does it cost to convert R12 to R134a?
It will generally cost you
about $200
to have a mechanic convert an AC system for you. If you want to replace a vehicle’s AC system, it will cost between $1,500 and $4,000 with an average cost of $2,750. If you decide to have a professional work on your car, you will have several options for where to get the work done.
Can I put R22 in my car?
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.
Can you use R22 gauges for 134a?
R134a refrigerant is an alternative that contains no chlorine and hence no ozone depletion potential. It’s a greenhouse gas, though, and it doesn’t work as well as R22. Secondly, can I use the same gauges for r22 and r410a?
No, you cannot
.
Why is R12 illegal?
In conclusion folks R-12 Freon was
banned due to the damage that it caused to the Ozone layer
. The Chlorine found in CFC refrigerants like R-12 would not break down in the atmosphere when vented or leaked. The Chlorine would then erode the Ozone bit by bit.
