Gwp of hfo-1234yf
WebThe HFO R1234yf is a low GWP alternative to R134a with similar pressure but with slightly less volumetric efficiency and cooling capacity. The GWP of R1234yf (4) is much lower than R134a (1430), and this is one of the reasons why it has been selected by most of the car industry as the replacement for R134a in Europe for automotive A/C. R1234yf ... WebGWP and zero ODP. HFO-1234yf, with zero ODP, the GWP of 4, and a very short atmospheric lifetime of 11days (Minor and Spatz, 2008), shows similar thermophysical properties to HFC-134a. (Calm, 2008) However, it exhibits a smaller volumetric cooling capacity and COP than those of HFC-134a. (Minor et al., 2010) In order to make better
