Estudo da energia dissipada na válvula redutora de pressão visando seu reaproveitamento na edificação

Abstract

This work studied a bibliographic research directed to the reuse of the dissipated energy through the pressure reducing valves existing in a building. In this sense, we propose the study of the building distribution system and analysis of the potential energy waste during the use of the pressure reducing valve aiming at the conversion to renewable energy. Thus, it considers the peculiarities of the water distribution networks including the characteristics of the pressure reducing stations and the consequent specificities in the use and installation of the pressure reducing valve, as well as explaining the types of hydraulic machines and fundamental quantities for the operation of these equipment. To survey the energy to be dissipated in the pressure reducing valve, check the total monthly volume of water supply, daily consumption per inhabitant, quantity of flow and pressure for system supply and head of each point to define the turbine type and generator

indicated for each system. Considering the high demand for energy and the need to develop alternative means of conversion, the elaboration of sustainable projects capable of enhancing building energy reuse is of paramount importance.
