Is R1234yf going away?

Under an Environmental Protection Agency mandate, R-134a will be phased out and R-1234yf refrigerant must be in all new cars by 2021.

Can I use R134a in a R1234yf system?

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. >>

Is 1234yf poisonous?

The refrigerant R1234yf is being considered for use in air conditioning systems in cars. Chemists now show that, in the event of a fire, it releases the highly poisonous carbonyl fluoride, and urge that its safety be reassessed.

Why is 1234yf refrigerant so expensive?

The problem we now have though is the price of 1234yf. 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.

How flammable is R1234yf?

R1234yf is a synthetic HFO refrigerant co-developed by DuPont and Honeywell as a successor to R134a for automotive air-conditioning applications. The biggest difference is R1234yf’s A2L flammability rating, which means it is mildly flammable.

How much does 1234yf cost per pound?

However, the average current market price of the R1234yf refrigerant is $120 per pound.

Is 1234yf flammable?

HFO-1234yf can be described as being “mildly flammable” as measured by standard methodology.

Why did they switch to R-1234yf?

The auto industry has transitioned some U.S. models to R-1234yf, although it’s not required by current U.S. law. The reason the auto industry is transitioning its U.S. models is to achieve commonality with European models, and to gain Corporate Average Fuel Economy (CAFE) “credits” from the EPA.

Why did they switch to R1234yf?

Is R1234yf better than R134a?

Refrigerant R1234yf has a low global warming potential of 4, compared to 1430 for R134a, and has thermodynamic properties similar to R134a, making it a desirable choice for future automotive refrigerants. R1234yf has a significant potential to be a drop-in replacement for R134a in the near future.

What is HFO-1234yf refrigerant?

R-1234yf, or HFO-1234yf is soon to be one of the most popular refrigerants in the world. Making it’s debut in the early 2000’s it has quickly rose to power and will soon be the dominant refrigerant in the automotive industry.

What is the difference between 134134a and 1234yf?

134a is a Hydroflurocarbon refrigerant while 1234yf is a Hydrofluroolefin refrigerant. While these are two separate classes of refrigerants they are in fact very close to each other. The only main difference is that the HFO refrigerants have a double carbon bond whereas HFCs do not. I read that 1234yf is flammable, should I be worried?

Can 1234yf cause a fire?

In 2012 Daimler began their own internal testing with 1234YF on some of their vehicles. They claimed that in some of their tests that when the refrigerant tank ruptured during an accident that the refrigerant ignited and caused a fire to occur. The video can be seen below.

What is the history of 1234yf refrigerant?

Well, to understand the history of 1234yf and the other HFO refrigerants we first have to go back in time to the 1980’s. Back then all automotive applications were using the CFC R-12 refrigerant for their air conditioning. R-12 was the original mainstream refrigerant that came from the 1930’s.
