Estudo da viabilidade e performance para implantação de Sistema de ar-condicionado tipo VRF no Setor de Aulas IV da UFRN. 2023. 59 f. Trabalho de Conclusão de Curso (Graduação em Engenharia Mecânica) - Centro de Tecnologia, Universidade Federal do Rio Grande do Norte, Natal, 2023.https://repositorio.ufrn.br/handle/123456789/56621The reality of the current market demands increasingly efficient air conditioning systems. The increased search for sustainable solutions has driven the sector to innovate in products with low energy consumption. And in design decisions, energy efficiency is a crucial factor. This case study aims to analyze the technical and economic forecast of implementing a retrofit in the existing air conditioning system. The standards for carrying out the project, software for calculating thermal load, computer simulation of the project and limitations of a system will be highlighted. And, by comparing the energy performance of conventional Split System and VRF systems, the best solution will be highlighted. Finally, it was concluded that the VRF system has a 36% lower operating cost.Split SystemVRFEficiência energéticabachelorThesisCNPQ::ENGENHARIAS
