Experimental analysis of R1234yf as a drop-in replacement for R134a in a small power refrigerating system

Experimental study of R1234yf as a drop-in replacement for R134a in an oil-free refrigeration system

“…Therefore, due to the similar thermal properties, R1234yf has a potential to be used as a drop-in replacement for R-134a in automobile air conditioners without any modification. [11] carried out an experiment to study the R1234yf drop-in performance in an R134a small power refrigerating system. The results indicate that the cooling capacity for R1234yf is 6% lower than R134a.…”

Overview of low GWP mixtures for the replacement of HFC refrigerants: R134a, R404A and R410A

“…Its operation conditions are limited in some applications due to its boiling point (-26°C). R134a is widely used in chillers (Sieres and Santos, 2018); in countries like China, the growth in the automotive industry has potentialized the consumption of R134a, and thus increasing from 25.52 thousand tons in 2007 to 75.05 thousand tons in 2015, with an annual growth of 14% (Tianduo and Xunmin, 2017); and in Mexico, R134a is still considered the leader in the market of mobile air conditioning (Posada et al 2017).…”

The Replacement of the R404A Refrigeration System with The Environmentally Friendly R448A, to Improve Convenience Store Energy Efficiency in Thailand

“…The R1234ze and R1234yf are categorized as Class A2L with a low GWP, which is an alternative for R134A. and not for because the performance of R134A, R1234yf and R1234ze were similar [18][19][20]. Therefore, fourth generation refrigerants; R407A, R407F, R407H, R410A, R448A, R449A, R442A, R453A, and R463A, are refrigerants mixed with HFC, HFO, HC.…”
