Gas for air conditioning recharge R 1234YF

Product Information

The main difference between the old style gas (R134) and the new 1234TF gas is down to its environmental credentials. The old R134 gas has a significantly higher global warming potential than the new gas. If the gas leaks from a car or van’s air conditioning system then it has a higher impact on the environment. R-134a and 1234yf systems are very similar to each other. In fact this was one of the reasons that 1234yf was chosen as an alternative refrigerant. A few of the major differences can be read below: Ansari, Naushad A.; Yadav, Bipin; Kumar, Jitendra (August 2013). "Theoretical exergy analysis of HFO-1234yf and HFO-1234ze as an alternative replacement of HFC-134a in simple vapour compression refrigeration system". International Journal of Scientific & Engineering Research. 4 (8). CiteSeerX 10.1.1.415.9796. The risk characteristics of the increased flammability of R-1234yf were evaluated in the SNAP ruling, but this difference prevents the refrigerant from being a direct drop-in replacement. In addition, the system components need to be rated for R-1234yf before the refrigerant can be used. The SNAP ruling recommends SAE safety standards J639, J1739 and J2844 for the applicable use cases. Some vehicle manufacturers made the switch a few years ago, and already require the latest gas when

Ok, so we’ve got the basic facts out of the way now on this refrigerant. Now let’s take a look at some of the more interesting points about this refrigerant.As I have said throughout this article there is a numerous list of automotive manufacturers that have already begun using the new 1234yf refrigerant. I may miss some here but I aim to show you some of the manufacturers that are currently using the new HFO refrigerant. The point here is to show you that this stuff isn’t going away and that in fact it is only becoming more popular. This data is from 2017 and a make list does not necessarily mean that all of their models are using 1234yf. Let’s take a look:

It is also designated R-1234yf as the first of a new class of refrigerants: [1] it is marketed under the name Opteon YF by Chemours and as Solstice YF by Honeywell. [2] R-1234yf is also a component of zeotropic refrigerant blend R-454B, an alternative to the R-410A refrigerant currently used in air conditioning and heat pump applications. The properties and regulatory fit of HFO-1234yf make it an ideal base molecule for electrified heavy-duty vehicles. Because EVs present unique challenges in cabin heating and battery cooling, innovators such as Chemours are constantly evaluating options to tailor the benefits of R-1234yf for electrified applications.The Montreal Protocol is a treaty that was signed in the late 1980’s by more then one-hundred countries. It’s goal was to rid the world of using Ozone depleting substances like CFC and HCFC refrigerants. This treaty was enacted in countries all over the world. The first target was CFC refrigerants such as R-12. In 1992 R-12 was phased out of the automotive market in the United States and was replaced with the newer HFC refrigerant known as R-134a. R-134a had the benefit of not containing Chlorine so with its usage there would be no danger to the Ozone layer. climate-damaging pollutants than its predecessor, R134a. If your vehicle requires the new gas, this is In October 2012, SAE International established a new Cooperative Research Project, CRP1234-4, which included members of thirteen automotive companies, to extend its previous testing and investigate Daimler's claims. [10] A preliminary update as of December 2012 [28] and a final report publicly released on July 24, 2013 [10] agreed that R-1234yf was safe to use in automotive direct-expansion air conditioning systems. R-1234yf was believed not to increase the estimated risk of vehicle fire exposure. The report further stated that "the refrigerant release testing completed by Daimler was unrealistic" and "created extreme conditions that favored ignition". [10] [29] The final report was supported by Chrysler/Fiat, Ford, General Motors, Honda, Hyundai, Jaguar Land Rover, Mazda, PSA, Renault and Toyota. Daimler, BMW and Audi chose to withdraw from the SAE R-1234yf CRP Team. [10] a b Scientific Assessment of Ozone Depletion: 2014 Full Report.

Because of the additional costs involved, and perhaps the ongoing uncertainty regarding timescales, the take up so far has been limited with only a fraction of A/C capable garages investing. This has created a gap in the number of qualified technicians able to service these vehicles. We have gone over the requirements to service 1234yf but now we need to cover what kind of tools that you will need. Like with most new technology comes new tools. Let’s take a look: By combining the EU’s policy on R-134a and now the United States’ public policy everyone knew that the most logical choice for an alternative was HFO-1234yf. Sure, there were companies like Daimler researching R-744 but this was not a viable alternative at this point in time. Production had to be increased on YF as soon as possible. Earlier this year, 2017, the Chemours company broke ground on a new 1234YF manufacturing plant in Corpus Christi, Texas. This new facility is expected to triple the company’s output of 1234yf. Chemours was just following suit though as the Honeywell corporation actually opened up their new three-hundred million dollar facility in Geismar, Louisiana earlier this year. R-1234yf has a higher vapor density than R-134a. Higher vapor density enables the use of a smaller compressor, reducing the system’s energy consumption. There were many disputes from numerous companies and organizations from all over the world to this test and claim from Daimler that the new refrigerant was unsafe for use. For a time it seemed like German Automakers were going to fight HFOs tooth and nail. They had their hearts set on R-744 CO2. Over the years though there have been numerous court battles and fines issued by the European Union but still Germany persisted against 1234yf.

In almost all hybrid and electric vehicles, the air conditioning system is also responsible for the Thermal Management of the battery to maintain maximum efficiency and prevent battery damage. This timeline put even more pressure on Honeywell and Chemours. In only a few short years later in 2008 they presented HFO-1234yf to the Society of Automotive Engineers Cooperative Research Program. (SAE CRP1234) The society concluded that 1234yf offered superior environmental performance and that 1234yf was safe to use in automotive applications. After this test came a whole host of other tests from companies, governments, and other organizations all over the globe. Everyone wanted to make sure that this new refrigerant was not only good for the environment but also safe. Remember now folks that the new YF refrigerant went up a flammability level to 2L. Was it safe to use? Most everyone said that yes, it was… but there was one company that disagreed. Daimler

If your car is manufactured from January 2017 you will have the latest refrigerant in your car. Some cars from 2014 also have the latest gas. If you look under your bonnet as shown in the picture below, there will be a label identifying which type of gas and how many grams of gas your car requires. PMM: The new refrigerant is more climate-friendly. But what is R1234yf and how does it differ from R134a? R-1234yf refrigerants for mobile air-conditioning systems have been widely used in passenger vehicles the past several years, but they are just now gaining traction in medium- and heavy-duty commercial vehicles. Environmental policies are driving the shift to R-1234yf, which has a Global Warming Potential (GWP) of <1 compared to R-134a’s GWP of 1,300.Let me start this off with saying that a 1234yf system is VERY similar to an R-134a system. If you are familiar with 134a repairs then you should be just fine with YF repairs as well. That being said there are a few points that I want to make to you before we move on to the next section: There is a slight difference as you go up in temperature but for the most part 134a and 1234yf work on very similar temperatures and pressure.
