What is R1234yf made of?

Honeywell HFO-1234yf is made up of hydrogen, carbon and fluorine, the same chemical components as the traditional coolants.

What is R134a made of?

The R-134a molecule is ethane-based and consists of carbon (C), fluorine (F), and hydrogen (H).

Is R1234yf propane based?

HFO-1234yf has an ASHRAE (formerly the American Society of Heating, Refrigerating and Air Conditioning Engineers ) rating of A2L (mildly flammable) and hydrocarbon refrigerant R-290 (propane) has an ASHRAE rating of A3 (highly flammable).

What type of gas is 1234yf?

1234YF is a hydrofluoro-olefin refrigerant developed by DuPont/Honeywell. Similar to 134a, 1234YF contains hydrogen, fluorine but also contains carbon elements. The difference is the two are significantly different when it comes to the harmful effects on the gasses contributing to global warming.

Is R1234yf harmful to humans?

One of their most recent studies found that R-1234yf is toxic. Now when I use the word toxic it is not like how other refrigerants are toxic. For example, if there is an ammonia leak then it can be extremely deadly.

How much does 1234yf cost?

The national average price of an R134A recharge in 2018 was around $200-$300 with the cost of the previous standard R134A refrigerant at $30 per pound. However, the average current market price of the R1234yf refrigerant is $120 per pound.

Is R134a poisonous?

Continued breathing of high concentrations of R134a vapours may produce cardiac irregularities, unconsciousness and death. Chemical hazards R134a vapours decompose when exposed to high temperatures with the formation of toxic and irritating compounds such as hydrofluoric acid, carbon monoxide and carbonyl fluoride.

Why R134a is not used in AC?

Note that R134a is also sometimes called “Freon,” even labeled as such on the can, so it’s best to be clear and use the names R12 and R134a. Because R134a is an HFC, not a CFC (stay with me for a minute), it does not have the ozone-destroying properties of R12. Bottom line, R134a simply doesn’t cool as well as R12.

Is R1234yf better than R134a?

R134a and R1234yf are similar, however, R1234yf was created as a more environmentally friendly replacement to R134a. The biggest difference between the two is that R1234yf is mildly flammable and does require special handling. R744 is carbon dioxide, so it is non-flammable.

Why is 1234yf so expensive?

Originally, we heard from the manufacturers that the price was so high due to development time and lack of resources to manufacture the product. But now, years have passed and fully functioning manufacturing plants have been opened.

Is R1234yf better than R-134a?

Can I buy 1234yf?

HFO-1234yf is a new class of refrigerants known as hydrofluoroolefins. These refrigerants are similar to HFC refrigerants except that they have a much much lower Global Warming Potential number. The only exception is buying for wholesale or when purchasing containers that contain less than two pounds of refrigerant.

What’s the difference between HFO-1234yf and R-134a?

HFO-1234yf has a global warming potential (GWP) of less than 1, compared to 1,430 for R-134a and 1 for carbon dioxide . This colorless gas is being used as a replacement for R-134a as a refrigerant in automobile air conditioners.

What kind of oil does the R-1234yf refrigerant use?

Refer back to my fact sheet above to see the boiling temperatures. 1234yf uses PAG oil just like R-134a but please note that it uses a different type of PAG oil. It is always safest to read the sticker labels under your hood or to consult the instruction manual before adding in any oil. Evaporator designs must meet JAE standard J2842.

Who is the inventor of HFO-1234yf refrigerant?

HFO-1234yf was developed by a team at DuPont, led by Barbara Haviland Minor, which worked jointly with researchers at Honeywell. Their goal was to meet European directive 2006/40/EC, which went into effect in 2011 and required that all new car platforms for sale in Europe use a refrigerant in its AC system with a GWP below 150.

Is it possible to retrofit R-12 to R-1234yf?

R-12 systems are still eligible for retrofit to R-134a. Retrofit from R-134a to R-1234yf can be done but is exponentially expensive. Pros: This system is designed to be very efficient, has low leak potential, and shouldn’t require service as frequently. Cons: It is more costly and complicated to maintain.
