Análise e comparação de dois projetos de climatização para o prédio do curso de Engenharia Mecânica da UFJF

Abstract

Currently, there is a growing demand for climate control environments in different segments of society. In this sense, it is important to understand how UFJF spaces can improve to generate a more friendly, welcoming environment that contributes to the excellence practice education of scientific and technical knowledge. The scientific method proposed in this work was built from the comparative analysis between two projects for a two-story pavement of the Department of Mechanical Engineering of UFJF. This environment is composed of both classrooms and teachers, as well as laboratories. The people who attend this place are undergraduate students, professors and university's staff. Thus, from the building plan, and from the initial property data, considering the external and internal factors the thermal loads were calculated, applied the air conditioning equipment selection methodology. In addition, a cost comparison was made by analyzing the IRR (Internal Rate of Return) and NPV (Net Present Value). Therefore, the present monograph intends to deliver the analysis of two HVAC projects to the UFJF Mechanical Engineering building, contemplating the most viable alternative, that after financial analysis, was the centralized VRF (Variable Refrigerant Flow) system.
