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 No, if you are 609 certified through the EPA already you are legally able to work on these new YF units. However, it may make sense to go through 609 training again and to take the test again as these tests have been updated to include newer YF questions.

Mixing HFO-1234yf with 10–11% R-134A is in development to produce a hybrid gas under review by ASHRAE for classification as A2L which is described as "virtually non-flammable". These gases are under review with the names of R451A and R451B. These mixes have GWP of ~147. [37] Zatz, David (October 1, 2013). "Chrysler adopting R1234YF". Allpar News (Press release) .

After the system has been fully charged, disconnect your lines, and reseal the valves just like your normally would. To accommodate the new refrigerant and ensure correct identification during servicing, new connectors have been introduced to the A/C loop, meaning new equipment is required. Due to the still significant parc of R134a equipped vehicles, dual recovery/charging stations are available, featuring separate refrigerant tanks and hoses for both gases. Alternatively, if you already have a good R134a station, or are new to A/C servicing, you may wish to consider a standalone R1234yf machine. You’ll also need a new refrigerant leak detector and a refrigerant identifier, if it’s not built into yourA/C machine. It was in the 1980’s that a team of scientists out of California realized that all of the Chlorine that was in CFC and HCFC refrigerants was causing damage to the Ozone layer. When vented or leaked the refrigerant would drift up and into the atmosphere. It is there where the Chlorine would do it’s damage. Eventually it got so bad that a thinning of the Ozone layer began to form over the Arctic. The scientists noticing this sounded the alarm and the world’s governments took action by creating the Montreal Protocol.

Shortly after confirmation from automakers that HFO-1234yf would be adopted as a replacement of R-134a automotive air-conditioning refrigerant, in 2010, Honeywell and DuPont announced that they would jointly build a manufacturing facility in Changshu, Jiangsu Province, China to produce HFO-1234yf. [18] In 2017, Honeywell opened a new plant in Geismar, Louisiana, to produce the new refrigerant as well. [19] [20] Although others claim to be able to make and sell HFO-1234yf, Honeywell and DuPont hold most or all of the patents issued for HFO-1234yf [18] and are considered the leading players in this area as of 2018. [21] Flammability [ edit ] For those of you in the distribution industry or even those of you who like to buy cylinders in bulk you should know that 1234yf is labeled as a hazardous material. You will need to follow certain restrictions if you plan on storing a significant amount of YF at your facility. It is best to read up on this topic and also to consult with your local fire department to ensure that you are in standard. 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.

Notably, these included limiting polluting refrigerants with a global warming potential (GWP) over 150, retrofitting air conditioning systems, and, most importantly, banning the sale of new vehicles with air conditioning systems using a refrigerant with a GWP over 150 from 1st January 2017, effectively outlawing R134a. As I am sure most of you know 1234yf is meant to take the place of the very popular HFC R-134a refrigerant. This has already happened in the European Union as of January 1st, 2017 and will be happening in the United States by the year 2020. (Model year 2021.) Know that those dates are the deadline though and some manufacturers are already using 1234yf on newer vehicle models. From 2017, a change in the law required the introduction of a new refrigerant – HFO-1234YF (also known as R-1234YF) – in air-conditioning systems of vehicles, replacing the widely used R134a. This has implications for automotive engineers and HVAC technicians, particularly when it comes to using appropriate gas leak detectors.
