For its vehicles that use R-1234yf Daimler will add and underhood “fire extinguisher” that consists of an argon gas canister with spray lines directed at all parts that could come in contact with leaking refrigerant. R-134a is not going to disappear in the same way as CFCs (chlorofluorocarbon) or R-12 did. Use a “drop-in” refrigerant: There are “drop-in” refrigerants that can be used in place of R22. I also wrote an article summarizing the announcement as well, which can be found by clicking here. At this point in time there are two main brand names, the Honeywell version called Solstice and DuPont’s/Chemour’s version called Opteon YF. How Much Is R-134a Refrigerant Per Pound in 2021? Recharging your A/C system with refrigerant can be a simple fix. The other new alternative to R134A is HFO-1234YF, which has similar properties to R134A but meets the new European global warming standards. How Much Is R-410A Refrigerant Per Pound in 2021? Despite those two drawbacks of CO2 there are automobile manufacturers who are moving forward with CO2 instead of 1234YF. The cons for using R-744 refrigerant are high initial cost for development (components must be designed for high pressures), in-vehicle and service equipment leak detection sensing required, specialized training for technicians, safety issues related to asphyxiation and high system pressures. FrostyCool 134a operates at lower head pressures and offers colder air and improved performance compared to HFC-R134a. While many automotive manufacturers are using R-1234yf in new vehicles German brands like Volkswagen, Porsche, Audi and BMW have committed to R-744 as their refrigerant of choice however they will use R-1234yf for vehicles sold in the US. Refrigerants with certain molecular structures have been identified as substances that can be harmful to the environment. R134a and R1234yf are similar, however, R1234yf was created as a more environmentally friendly replacement to R134a. The EU threatened Germany with law suits and sanctions, but so far nothing has come of it. There are three refrigerants that can be used to replace R-134a: R-1234yf, R-152a and R-744. It was originally developed to replace R12 in car AC systems. Most passenger cars or light trucks manufactured since 1995 were built for R-134a. Those familiar with 5-gas analyzer readings from a vehicle’s exhaust know that high CO2 readings indicate a nearly ideal air-fuel ratio, efficient combustion and optimum catalytic converter operation. Most work okay but will result in decreased reliability and performance. Avalanche R134a Refrigerant 10oz. Not exactly. Lastly, this certification is required before a technician can purchase any MVAC refrigerant (and not just R-12 as it had been prior to the Jan. 1, 2018 — effective date of the new ruling). To date, most auto manufacturers are using the hydrofluoroolefin (HFO) refrigerant R-1234yf as the replacement of choice for R134a. R-134a first began to see widespread usage in 1992 and took over the automotive market entirely in 1994. For this reason, you should only use drop-ins for quick, temporary repairs and have a different long-term replacement plan in mind. It has zero Ozone Depletion Potential (ODP) and a low GWP of 124. I predict in the next ten to fifteen years that Carbon Dioxide will be the main refrigerant for automobiles. 1234YF is a Hydroflurooolefin refrigerant and has a Global Warming Potential of four and it does not damage the O-Zone layer. The biggest difference between the two, is that R1234yf is mildly flammable and does require special handling. These tradable credits can help manufacturers comply with new, stricter fuel economy standards. However, if you have that same conversation with someone in Germany you may get an entirely different story. R-1234yf will be in use for many years but in the distant future R-744 may ultimately replace it. If a system has R22 in it already you cannot use a replacement refrigerant to simply add to the R22. When used in multi-zone automatic A/C systems, it is possible to create an optimal microclimate for each individual passenger. Vehicle manufacturers will begin the slow process of switching newer models over to 1234YF and as the years pass you will see more and more vehicles coming in with 1234YF systems. ZeroR Max Seal 4oz Aerosol (ES Pro Seal), Replacement for R134a & R12 Liquified Petroleum for Non mvac use in Non self Sealing containers, Made in USA 4.2 out of 5 stars62 $22.96$22.96 It is also used as medium temperature systems … CO2 has a GWP of 1 while R-134a has a GWP of 1,320. When CO2 was used in the early twentieth century it resulted in many part failures due to the constant high operating pressure. FrostyCool 134 can be used to replace HCF R-134a and CFC-R12 substitute refrigerants in mobile air conditioning and refrigeration units. No R-12 refrigerant has been manufactured since 1996 and the only supplies left are “virgin” (original containers) or refrigerant that has been legally recovered and reclaimed. (Unlike 1234YF). So, we are looking at less than five years until 134a is phased out nationally. Some people contend that there are still issues with HFO-1234yf that needs addressing. For A/C use in automobiles R-152a is a more efficient refrigerant than R-134a. The basis of the rule was that by the year 2020, or MY 2021, all new manufactured or imported vehicles would not be able to use R-134a. Not bad if I say so myself. VALUE – The net weight when compressed is 6oz but it is equal to 16oz of R134a once installed! 134a was directly contributing to Global Warming and the call to phase out had begun. As more time passes the more this price will rise until we get to 2020 and then we may even see the price get to R-22 levels of around $300-$350 a cylinder. Another advantage of R-744 systems is that there is no condensation of the refrigerant.
