R1234yf and R744 as alternatives to R134a at mobile air conditioners

Journal of Energy Systems, 2021
R1234yf is a synthetic HFO refrigerant co-developed as a replacement refrigerant for R134a in automotive air conditioning applications. Thus, in this study, alternatives to the R134a refrigerant that were removed from the newly produced devices were examined.

Theoretical analysis of R1234yf and R1234yf/R125 mixture as replacement of R134a in vapor compression system

International Journal of Low-Carbon Technologies
Abstract In this article, in order to reduce the climate hazards caused by global warming, a new environmentally friendly mixed refrigerant, R1234yf/R125 (with a mass ratio of 95:5), is introduced. Alongside R1234yf, the article conducts theoretical research to assess the feasibility of substituting R134a in vapor compression systems ...
