ESTUDO DA VIABILIDADE PARA ADAPTAÇÃO/SUBSTITUIÇÃO DE UM SISTEMA DE CLIMATIZAÇÃO CONVENCIONAL DE GRANDE PORTE POR VRV. 2019. 38f. Trabalho de Conclusão de Curso (Graduação em Engenharia Mecânica) - Universidade Federal do Rio Grande do Norte, Natal, 2019.https://repositorio.ufrn.br/handle/123456789/43030The present paper aims to study the feasibility of adapting and replacing a large conventional air conditioning system with VRF (Variable Refrigerant Flow). The evaluation was made in the building of the School of Sciences and Technology (SST) at the Federal University of Rio Grande do Norte, where the current climate system will be replaced by VRF and the electrical installations will be used. The work seeks to evaluate the efficiency of the VRF air conditioning system compared to conventional and design a better use of the already installed system, also looking for material savings and later energy saving. In addition, the location of the condensing machines was evaluated, since the weights are different from conventional air conditioning machines. In this proposal the same internal thermal loads and infiltration rates are adopted and air renewal was included. Finally, the results show that the substitution generates a significant reduction of the electric energy consumption, the better distribution of the thermal load, besides a high operational control of the machines.Attribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/ClimatizaçãoClimatizationVRVVRFAr-condicionadoAir conditioningbachelorThesis
