Abstract The imminent phase-down of the common refrigerant R134a is calling for lower GWP alternatives. Real alternatives must have a lower global warming impact and they should be not flammable. In this context, R513A (azeotropic mixture made of R1234yf and R134a at 56% and 44% by mass) has been proposed as alternative to R134a due to its similar ...

R513A flow boiling heat transfer inside horizontal smooth tube and microfin tube

International Journal of Refrigeration, 2019
Abstract This paper presents experimental results for R513A flow boiling inside a 3.5 mm ID horizontal smooth tube and inside a 3.4 mm ID horizontal microfin tube. R513A is an azeotropic mixture made of R1234yf and R134a (56% and 44% in mass), and it is proposed as a direct substitute of the common R134a.
