AB - In this paper, the feasibility of two low global warming potential  refrigerants R513A and R1234yf as alternatives to R134a was tested in an  automotive air conditioning system in winter. The test results showed that  the heating capacities of R513A and R1234yf were 2% and 4% lower than that  of R134a, and their COP were 3-9% and 6-19% lower than that of R134a,  respectively. It revealed that R513A can be used as a transition product to  replace R134a, and R1234yf required further improvements to improve the  energy efficiency.
