SISTEMA DE RECALQUE COM OU SEM INVERSOR DE FREQUÊNCIA: ESTUDO DE CASO DE UMA HABITAÇÃO VERTICAL

Abstract

The repression system, also called adduction, is essential to overcome unevenness, especially in vertical dwellings. Aiming at mitigating implementation costs and optimizing the use of electricity, practices and technologies are always sought to optimize the operation of these systems. The present work aimed to analyze, from a case study, the main energy impacts when using a frequency inverter in the water boosting system of a vertical house with 36 floors. The system was dimensioned with and without said equipment, in the scenario in which the drive of the motor-pump set by the inverter was considered, different pump operating times were simulated in order to understand which option would present the best economic viability without affecting the operation. of the system. The results suggest that the use of the frequency inverter in the building supply can present a significant reduction in piping expenses, however it is important to verify the ideal operating time of the motor-pump set in order to obtain the best technical, economic and energetic cost-benefit.
