Abstract
The present work has the purpose of analyzing the cold airflow coming from air conditioners of professors’ offices selected as models of the upper floor of the Engineering Building of UFGD. Using tools and Ansys Fluent software, a model was made for each office and relevant model data were obtained regarding air behaviour as a temperature and velocity function, taking into account the internal thermal load of each model and the heat generated due to solar incidence on models with windows. Thus, it was possible to analyze whether or not the air conditioners of each model were correctly dimensioned, as well as to recommend the necessary velocity to obtain thermal comfort at 24 oC. Finally, a proposal for improvement was made using a photovoltaic solar system, as well as the generation and energy saving parameters analyzed with the proposed system for the energy sustenance of the air conditioners.
