Just so, is there a difference between r134 and r134a?

2 Answers. R134a.. R134 and R134a have same chemical formula and atomic weight but different chemical structures. R134 has NBP of about -19 C whereas R134a has a NBP of about -26C.

Subsequently, question is, what is the replacement for r134a? To date, most auto manufacturers are using the hydrofluoroolefin (HFO) refrigerant R-1234yf as the replacement of choice for R134a. The 2013 Cadillac XTS was the first U.S.made vehicle to use the new refrigerant. With a GWP of 4 (instead of 1,430 for R-134a) R-1234yf is more environmentally friendly.

Similarly one may ask, is all 134a refrigerant the same?

Yes, all R134A is the same thing, stay away from leak stopper, not to be confused with leak detector, the leak detector is alright to use.

Can you use 134a in home AC?

R134a is a hydrofluorocarbon that does not cause environmental harm. While used mostly in cars, only one home air conditioner has been made, as of November 2010, that uses R134a as a standard. As of 2010, new home air conditioners that are produced must use a refrigerant that does not deplete the ozone.

What does the A stand for in 134a?

R134a is also known as Tetrafluoroethane (CF3CH2F) from the family of HFC refrigerant. R134a.. Here “a” is used to denote that it is an isomer. R134 and R134a have same chemical formula and atomic weight but different chemical structures. R134 has NBP of about -19 C whereas R134a has a NBP of about -26C.

Can I use automotive r134a in a refrigerator?

Can you use R134A for a car in a refrigerator? R-134a, if manufactured to prescribed tolerances, is applicable to both systems. Some manufacturers have different connections on the cylinder or drum, but adapters are available. Don’t use premixed oil/refrigerant in the domestic refrigerator.

How much freon does a refrigerator hold?

Refrigerant Charge

This amount is normally found on the model plate or manufacturer’s label, and it is measured in grams or ounces. The amount ranges from less than 1 ounce in small refrigerators to more than 6 ounces, or from 28.35 grams to about 185 grams.

What chemicals are in r134a?

Refrigerant R134a. The refrigerant R134a is the chemical compound tetrafluoroethane comprising of two atoms of carbon, two atoms of hydrogen and four atoms of fluorine. Its chemical formula is CF3CH2F. The molecular weight of refrigerant R134a is 133.4 and its boiling point is -15.1 degree F.

Why is r134a a good refrigerant?

R134a has fairly good dielectric properties as it has high thermal stability, low boiling point, and chemical inertness against the construction materials used; and is non-toxic and non-flammable. . A dielectric substance in its gaseous state can be used to prevent electric discharges.

What is r in refrigerant?

Chemical refrigerants are assigned an R number which is determined systematically according to molecular structure. Common refrigerants are frequently referred to as Freon (a registered trademark of Chemours).

What kind of refrigerant goes in a refrigerator?


How much should I add to 134a?

Most newer passenger car A/C systems do not hold much refrigerant (only 14 to 28 oz.), so you don’t want to add too much if the system is low. One can of R134a typically holds 12 oz. of refrigerant.

Does 134a have oil in it?

Yes there is oil in the system to keep the compressor lubricated. It is carried throughout the system in the refrigerant. It is usually added in when the system is charged.

Can 12a replace 134a?

HC-12a, also called ES-12a, OZ-12a, and Hydrocarbon Blend B, is a “drop-in” replacement refrigerant for Freon-12 and to a lesser extent, R-134a. Unlike R-134a, HC-12a is completely compatible with the hoses and oils used in R-12 systems, making the conversion much easier to accomplish.

Can you mix r134a with synthetic r134a?

Can I put one can of synthetic and one can of regular r-134a freon? unless you‘ve already bought it, just use two cans of whatever is cheap. ALL R134a is “synthetic“. There is no naturally occurring R134a.

Is r134a flammable?

Note: all refrigerants are FLAMMABLE, including R22. HFC-R134A – IS NOT labeled FLAMMABLE, but NOTE: it has a rated Ignition Temperature (F>) of 1390°F to 1436°F subject to different MSDS sheets from manufactures.

Does r134 brand matter?

No. It’s a very specific formulation. Brand shouldn’t matter. R134a is patened by dupont.

How often do you recharge AC in car?

To get back to the question of how often an AC system needs to be recharged, the answer is, “it depends.” There’s no service or maintenance schedule here – you don’t need to recharge your air conditioning system every year, or even every two years.

Is r134a heavier than air?

Yes is the correct answer. Refrigerant, and in this case I am speaking specifically about R-134a, but it’s typical of refrigerant gases, is heavier than air. Always check with the refrigerant manufacturer, but the chemical composition of R-134a is all the same regardless of the name on the canister.

What is the best r134a refrigerant?

The Best Car AC Refrigerant
  • DuPont Suva R-134a Refrigerant.
  • REDTEK A/C Refrigerant with Gauge Hose.
  • Interdynamics Artic Automotive Refrigerant R-134a.

Can I use 134a instead of 1234yf?

yes R1234yf Freon gas can be replaced by R134a; the newer systems were designed with this in mind so no, there will be no damage to the compressor but some time in the future doing so may become illegal. >>
