Projeto de um sistema de ar comprimido com programa computacional

Abstract

The present work aims to optimize the energy efficiency of a compressed air system from a small company in Northern Paraná. The overall objective is the application of the concepts of energy efficiency, statistics, and fluid mechanics and found in the literature in order to the compressed air system studied get a better energy performance. To carry out the work was necessary to process the data obtained in the company, such as pneumatic equipment consumption, utilization factor, uniqueness and length of the pipes, and to gather information in the literature in order to compare the system studied to the model found in the literature and thus optimize it in order to increase its energy efficiency, in other words, reduce the pressure loss, leakage and energy consumption, while optimizing the physical space in the company and facilitate future modifications in the system. Furthermore, were developed a computational tool on Excel that was used to help with the calculations needed during the development of the project. In the results are shown the recommended layout of the air compressed system, the material chosen for the pipes, the diameter calculated for the distribution and service lines and the selected compressors to feed the system. Concluding that the air compressed system dimensioned can feed the machines with better quality air compressed and energy efficiency.
