Gas for air conditioning recharge R 1234YF

Product Information

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. Some of you may be groaning at the extra steps when compared to R-134a. Well, with all things, there is a reason why these are performed. The fifteen percent precharge and leak detection step is key to catching a leak on your vehicle before it has been fully charged. If we catch the leak early while the charge is still low we can save loss of refrigerant, save your shop some cash on that refrigerant, save the customer money, and also prevent further damage to the environment. It’s a win win for all involved.

Other additives have been proposed for lowering the flammability of HFO-1234yf, such as trifluoroiodomethane, which has a low GWP due to its short atmospheric lifetime, but is slightly mutagenic.

But what is R1234yf and how does it differ from R134a? 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

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. The AC Pro R-1234yf Air-Con Recharge replaces refrigerant and oil from your A/C system and contains UV dye to assist with detecting and locating leaks in metal and rubber components. This canister makes it easy to maintain and service your A/C system without the need for expensive equipment and training. It is designed to work with A/C PRO CERTYF102 R-1234yf Gauge and Hose only (sold separately). 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:

The recovery and recycling procedures on 1234yf machines are basically identical to R-134a machines. The only differences that you will notice are: US6969701B2 Azeotrope-like compositions of tetrafluoropropene and trifluoroiodomethane". Google patents . Retrieved 26 July 2018. The flammability issue has attracted a lot of attention, prompting the industry to conduct some serious third-party testing. The bottom line is this: The refrigerant will burn, but it takes a lot of heat to ignite it and it burns slowly. Almost every other fluid under the hood will light more easily and burn hotter than R1234yf, so the industry has determined that with proper A/C system design, it does not increase the chances of fire in the vehicle." [16] Lo and behold there was found to be another problem with R-134a. Instead of the Ozone layer issue we now had a new issue called Global Warming Potential. Global Warming Potential, or GWP, is a measurement of how much heat a greenhouse gas can trap in the atmosphere. The basic measurement on GWP is Carbon Dioxide which measures as one. This is our standard. Now, if we look at R-134a’s GWP number we can see a number of one-thousand four-hundred and thirty. Quite the difference here folks. We can now begin to see why a substitute for 134a was needed as well. Enter HFO-1234YF

Mostly it will be automobiles that use 1234yf. Eventually we will see medium duty and even heavy duty vehicles come over to the YF side as well. 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 terms of its global warming potential, HFO-1234YF has a GWP of less than one which makes it less harmful than the equivalent mass of carbon dioxide (1 GWP) and sits well below the limit of 150. R134a, on the other hand, has a GWP of 1430. The benefits of the new refrigerant are therefore clear from an environmental viewpoint. As of 2018, it is believed that 50% of new vehicles around the world have an air-con unit using HFO-1234YF, thus making a huge, ongoing reduction in greenhouse emissions.

HFO-1234yf was developed by a team at DuPont, led by Barbara Haviland Minor, which worked jointly with researchers at Honeywell. [8] [9] Their goal was to meet European directive 2006/40/EC, which went into effect in 2011 and required that all new car platforms for sale in Europe use a refrigerant in its AC system with a global warming potential (GWP) below 150. [10] [11] While a new certification is not necessary there is additional training available through SAE Spec J2845. This training will go over specific requirements and techniques when servicing either 1234yf or R-744 mobile air conditioning systems. The easiest way to acquire this training is to retake your 609 certification exam through MACS Worldwide. They have updated their test to include YF material.

1234yf Necessary Tools

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