It has a much lower global warming potential (GWP) compared to HFC-134a. This refrigerant can only be used in newer vehicles whose air conditioning systems use R1234yf. Perhaps the most significant difference between R134a and R1234yf is the environmental impact. As previously mentioned, R1234yf has a lower GWP compared to R134a.
What does HFC-134a smell like? HFC-134a is a nonflammable, colorless gas or liquified gas with a faint ethereal odor. The odor, characterized as weak and nonirritating (Shulman and Sadove 1967), may not be noticeable for most individuals and thus will not serve as a warning property. How big is the high side service port on an R134A?
The application of a mixed refrigerant HFO1234yf/HFC134a (89:11, by mass) of GWP 144 in a vehicle air-conditioner system with and without an internal heat exchanger was studied under refrigerating and heating conditions, and it was compared with an R134a original system. The results show that under refrigerating conditions, the refrigerating capacity of the HFO1234yf/HFC134a system with an
Car air conditioning regas - HFC134a vs R134a - are they the same thing? : r/hvacadvice. Reading online these appear to be the same gas just with a different name, but my local garage refused to do the regas because the label was different to what was on their bottle. Just looking for some confirmation if these are the same or not as everything
