HFC refrigerants as R134a, R404A, R407C and R410A are commonly used in heating, air conditioning and refrigeration (HACR) systems since Kyoto protocol. However, they are phased-out due to their high global warming potential (GWP). There are various options to replace high GWP refrigerants, among all hydrofluorolefin (HFO) fluids, such as R1234yf, represents an excellent alternative. With GWP <1, R1234yf is a promising substitute for R134a. This paper presents the most relevant researches concerning the application of R1234yf in the last decade. This review paper regroups experimental and theoretical studies which assess the performance of pure R1234yf as working fluid of the compression systems such as mobile and residential air conditioning, air and water heat pump, domestic refrigerator and freezer. Studies depict that R1234yf can be recommended for small-scale systems instead of R134a, but an optimization process is necessary to achieve the optimum operating conditions.

R1234yf制冷剂在供暖,空调和制冷系统中的应用:十年研究

自《京都议定书》以来,HFC制冷剂(如R134a,R404A,R407C和R410A)通常用于加热,空调和制冷(HACR)系统。但是,由于其较高的全球变暖潜能(GWP),它们已被淘汰。在所有氢氟烯烃(HFO)流体(例如R1234yf)中,有多种选择来替代高GWP制冷剂,这是一个很好的选择。当GWP <1时,R1234yf可以替代R134a。本文介绍了最近十年有关R1234yf的应用的最相关的研究。本文对实验和理论研究进行了分组,评估了纯R1234yf作为压缩系统(如移动和住宅空调,空气和水热泵,家用冰箱和冰柜)的工作流体的性能。
