Abstract
The third generation of fluids, the hydrofluorocarbons (HFC) was created as a main alternative to solve high ozone depletion potential (ODP), which was introduced by the previous generation. Even so, there is still considerable contribution in a high global warming potential (GWP.) For example, R134a is the most significant HFC, but it has a high GWP (1430). For this reason, it is necessary to transition to the fourth generation of refrigerants low-GWP. This article is intended to show a review of R1234yf as one of the ways to get the last family of fluids to replace HFC., The subjects discussed in this article are its application in the vapor compression refrigeration systems and thermal heating as refrigerators, air conditioning systems, heat pump, as well as Organic Rankine Cycle for energy generation. In these areas are most of the theoretical and experimental studies about this fluid. The greatest impact of R1234yf was
reflected in the implementation of automotive air conditioning systems as a result of restrictions imposed by The European Union over refrigerants with high GWP.
