If you work with hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) or sulphur hexafluoride (SF 6), you may need to: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. Some vehicle manufacturers made the switch a few years ago, and already require the latest gas when Evaporator designs must meet JAE standard J2842. YF is tougher on evaporators then 134a and this new standard is to prevent wear and tear and premature failure. a b c d e f g Lewandowski, Thomas A. (July 24, 2013).

In fact, proactive maintenance of the air conditioning system is even more important here as the air con system in electric cars is also used for thermal management, that is, the cooling of components including the batteries and electric motors, which can become very hot with extended use. By cooling the battery, the air conditioning system supports effective charging processes and contributes significantly to the vehicle's performance and battery life. So regular air con maintenance is no longer just for comfort.HFO 1234yf: The ideal low Global Warming Potential refrigerant for mobile air conditioning and chillers has been developed at Buffalo Research Laboratory by Honeywell Fluorochemicals with the aim of replacing R134a in motor vehicle air conditioning. 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. 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.

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: Detects Leaks: More than just an air con recharging treatment, the UV dye helps find leaks in metal and rubber components available in selected garages (see the full list at the end of this article). Book an air con recharge 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. 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.

In 2017, European directive 2006/40/EC finally came into full effect. The eagerly anticipated legislation requires that all newly designed cars and LCVs fitted with A/C, and manufactured for use in the EU, must use a refrigerant with a global warming potential (GWP) of 150 or less. GWP measures how much energy a gas absorbs compared to the same quantity of CO2 over a 100-year period, so in simple terms, the higher the number, the bigger the environmental impact. 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. R1234yf is the new super low GWP refrigerant replacing R134a in automotive air-conditioning, used in some new cars as early as 2011 and all new cars manufactured in Europe from January 1st 2017. Our gas in 5 kg cylinder certified T-PED / EN 13322-1 is the new generation ecological gas, ideal for recharging air conditioners / air conditioners in new cars (W21.8 ”x 1/14” valve) UN 3161 HFO-1234yf has been shown to atmospherically transform into the ultrashort PFAS trifluoroacetic acid (TFA) leading to potential for wet and dry atmospheric deposition [39] See also [ edit ] Why has there been such a delay between passenger and commercial vehicles employing the new refrigerant?

To help mitigate this environmental risk, the new EU directive stated that all refrigerant will need to have a global warming potential of less than 150. Unfortunately, the R134 has a potential of 1430! This high figure equates to the R134 having 1,430 times more impact on global warming than carbon dioxide. 1234YF Gas – The Cost 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 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.
