WebFeb 25, 2024 · R-404A began seeing usage in 1996 after the phase out of CFC R-502 due to it’s Ozone Depletion Potential. R-404A is a ternary refrigerant blend consisting of the HFC R-125 (forty-four percent), HFC R-143a (fifty-two percent), and HFC R-134a (four percent). WebApr 13, 2024 · Note that R134a has the highest cooling capacity among the alternative refrigerants, and, in fact, has the largest latent heat favoring heat absorption (as shown in Table 1). For example, for a charge of 90 g, R134a represents an increase of 8.7% in its cooling capacity compared to R1234ze(E), whose latent heat is 6% lower than that of …
