Gas for air conditioning recharge R 1234YF

Product Information

In 2006 the European Union came out with a directive known as 2006/40/EC. This directive’s goal was to reduce the emissions of fluorinated greenhouse gases from mobile air conditioning systems. This would be a gradual phase out across the European Union. The end goal was to have automobiles using refrigerants that had a Global Warming Potential, or GWP, number of one-hundred and fifty or less. The first major date of the phase out was 2008, then 2011, and then finally on January 1st 2017 any new vehicle using a refrigerant with a GWP higher then one-hundred and fifty would be banned from the European Union. The problem here was that there wasn’t a viable alternative to HFC refrigerants at the time this directive was made. I’m sure you’ve heard of the expression: Necessity is the mother of invention. As of November 2021, R-1234yf has been listed as a proposed alternative under the EPA SNAP (Significant New Alternatives Policy) Program. “In anticipation of the publication of the final ruling, many OEMs are now actively developing systems using R-1234yf,” she said. Also driving this shift is the mandated HFC phasedown defined by the AIM (American Innovation and Manufacturing), which began January 1, 2022. Spalding shares additional insights with SAE Media in the following Q&A. Within an hour the whole recharge process is completed and you will once again have refreshing cool air on demand.Our trained technicians will show you the difference in your AC before and after recharge. Vehicle air conditioners that are not recharged regularly will be less effective and have to work harder to produce cool air. This puts more strain on the engine and uses more fuel. If your air conditioning system has not been recharged in the past two years it will dramatically reduce efficiency. Recharge or No Charge

The product can be handled in repair shops in the same way as R-134a, although it requires some different, specialized equipment to perform the service. One of the reasons for that is the flammability of HFO-1234yf. [16] Another issue affecting the compatibility between HFO-1234yf and R-134a-based systems is the choice of lubricating oil. [17]

The properties and regulatory fit of HFO-1234yf make it an ideal base molecule for electrified heavy-duty vehicles.”

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. You may not be seeing very many cars come into your shop today with YF refrigerant, especially here in the United States. There is a reason for that. Yes, there a lot of cars on the road that are using this new refrigerant but these cars are so new that most of them are falling under warranty when something goes wrong. What we are seeing today, October 2017, is a lot of dealerships doing the YF repairs. If we wait a few more years, say 2019-2020 I predict that a lot of the aftermarket shops out there will begin to see the demand for YF repairs. It just takes time folks. Hopefully by then the cost would have gone down. With 1234yf systems they have added a Suction Line Heat Exchanger, also known as an internal heat exchanger. This is an additional component located before the expansion valve. It is a state change helper that is used to improve overall efficiency of the unit. You may have even noticed these on newer model 134a systems as well. There are no moving parts on this addition as it is part of the hose line. 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 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:Wang, Ziyuan; Wang, Yuhang; Li, Jianfeng; Henne, Stephan; Zhang, Boya; Hu, Jianxin; Zhang, Jianbo (30 January 2018).

A new EU directive came in to operation in January this year that meant all new cars must now only use the new air conditioning gas 1234YF. The questions asked are always; What’s the difference and why change the type of gas? In this article we have a look at the 1234YF gas and help guide you on the difference between the new and old gas, and what you need to know and consider. 1234YF Air Conditioning Gas – The Difference The significant difference is due to R-1234yf being a hydrofluoroolefin (HFO), a molecule that has a very short-lived atmospheric life,” said Christina Spalding (below), account manager for The Chemours Company, which makes Opteon YF (R-1234yf) refrigerant. “Where hydrofluorocarbon (HFC) R-134a remains in the atmosphere an average of 12 years, R-1234yf’s atmospheric lifetime averages a mere 11 days.”

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. Schaeber, Steve (August 17, 2016).

For further guidance on how to get the most out of your air conditioning, take a look at our guide on carThere was one major bump in the road of HFO-1234yf to becoming the dominant automotive refrigerant. 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. In the video there is a test with 1234yf leaking and then there is a test with R-134a leaking. The video speaks for itself. If you use or service equipment containing HFCs being phased down, ask your supplier for advice on alternatives.
