Avaliação de sistemas de condicionamento de ar para salas de prédio público

Abstract

This paper assesses the air conditioning systems for rooms on one floor of the building of Central Administration (Rectory) of the Federal University of Santa Maria. A survey of the installed equipment has been conducted together with the calculation of the required heat load and through a study of the possible systems to be installed, selecting the system that best meets the building characteristics and energy performance. Held the choice of VRF system (Variable Refrigerant Flow System) as the best alternative, the list of equipment with the estimated cost of implementing the system design was done. The proposed system has proved to be a good alternative energy point of view, including reduction in the estimated consumption of approximately 30%, however, from economic point of view not found to be a good alternative for the building, as installation costs are high and the return time is greater than the life of the system itself. The use of the VRF system is more suitable for new installations, serving as an alternative to more traditional systems, but replacing an installation operating system for a VRF in order to reduce energy costs is not an economically viable alternative.
