But you write the nonsense. After all, the websites themselves change the 1234yf to 123a, because probably the companies themselves are afraid of possible lawsuits if an accident happened. Moreover, how many cars with the r12 factor used to have air conditioning? 1234yf is less efficient, and it is manufactured by Honeywell and DuPont on exclusivity, not basf, and where do you get this information from. As of today, the R1234YF 5kg cylinder costs 3200 PLN, and 12kg r134a 280 PLN.
From this place I have to thank the wonderful uni EU for the fact that it cares for our wallets and our health.
Quote: HFO-1234yf less efficient than the current R-134a refrigerant
The analysis of the physical and chemical properties of HFO-1234yf showed that it is about 8-10% less efficient than R134a, which means that the air conditioning system will have to use more energy to work, which will translate into an increase in fuel consumption by 5%.
Quote: HFO-1234yf dangerous to humans
Compared to its predecessor, the new coolant is theoretically less harmful to the environment (taking into account the Global Warming Potential index), but it is flammable. What's worse, when it ignites (at 405 ? C), it releases hydrogen fluoride. This, in combination with water (e.g. supplied during extinguishing), turns into very dangerous hydrofluoric acid. This acid is deadly to humans - it easily penetrates the skin into the human body and if it is not hospitalized very quickly, it has no chance of saving it. That is why this measure poses a threat to people, especially in a collision or car accident. However, among the potential victims are mainly firefighters responsible for extinguishing a burning vehicle.
Quote: Tests confirm the harmfulness of HFO-1234yf
Tests carried out by Daimler (a manufacturer of Mercedes-Benz cars), the German Federal Institute for Materials Research and Testing (BAM) and German journalists from Auto Bild and Zeit, clearly showed that HFO-1234yf is a poisonous, flammable agent and under certain conditions even explosive. The European Commission appeared deaf to these allegations, and rejected Daimler's request to delay the marketing of HFO-1234yf as a refrigerant. However, she emphasized again that it is completely safe and that every newly homologated car approved for sale in the EU will have to have it.
