Análise de sistemas de condicionamento de ar (VRF e VAV) para o bloco de engenharia da Universidade Federal da Grande Dourados

Abstract

The present work aims to complement and compare the energy performance of both VRF and VAV type air conditioning systems for the application on Engineering building of the Federal University of Grande Dourados - MS. This performance is analyzed through calculations of the building thermal loads, where thermal losses are mentioned due to the conduction and insolation in the building structure, as well as the gain of heat through the human body and equipment that integrate the refrigerated rooms. The information and data required for such calculation were obtained through the literature, where, after analyzing the amount of total thermal load that the building needs for the air conditioning, the equipment were selected for both the VRF and VAV systems, whose catalogs were available on the internet containing the necessary data for the selection. Finally, the energy performance study of the two systems for the building was realized using the installed power per floor of each one of them.
