Abstract—The cooling systems industry is essential in the supply chain of biological products, in the conditioning of spaces for comfort conditions or in industrial processes. This makes it essential for the life of the human being, however, it requires a high demand for energy to operate these systems worldwide, which results in the search for new technology that helps reduce the energy consumption of cooling systems. In this proposal, the operation of an ejector installed in an experimental cooling system is analyzed by CFD. In this study, the ejector is simulated on a two-dimensional geometry, based on experimental results, using R134a as a working fluid and commercial software ANSYS FLUENT 19R1. As a result, the behavior of the velocity vectors was obtained, where there is evidence of recoil in the secondary flow in different operating conditions which leads to an unstable behavior of the experimental system to the imposed operating conditions and an approach in the nozzle outlet primary to the mixing chamber, reduce this behavior.
