Dissertação Acesso aberto (Open Access) Estudo comparativo entre metodologias de dimensionamento de sistemas prediais de água fria de um hospital localizado em Belém do Pará, de acordo com a atualização da nbr 5626(Universidade Federal do Pará, 2023-03-30) MACHADO, Cláudia Letícia da Silva; SANTOS, Aline Christian Pimentel Almeida; http://lattes.cnpq.br/1388841813412015; ADAM, Katiucia Nascimento; http://lattes.cnpq.br/2498018628901734The hydraulic installations must be designed and built in such a way as to ensure the uninterrupted supply of water, in sufficient quantity, at adequate pressures and speeds, under appropriate conditions for the development of human activities and for human consumption, ensuring comfort to users including the reduction of noise levels in pipes. These conditions are met from the technical standards that determine hydraulic parameters and calculation methods to be followed by designers, who take into account a theoretical study of pipe and connection sizing that, in practice, due to water consumption and practical operation, ended up causing the adequacy of manufacturers of sanitary appliances, development of more efficient technologies. Through laboratory tests, many manufacturers began to provide essential technical information for the development of more assertive projects, such as the actual water consumption of the appliances, especially the characteristic curves of flow as a function of pressure, fundamental for use in the design of water systems and for the development of new methods, in order to consider the variable flow in the points of consumption. Tied to this new scenario the updating of technical standards among them the NBR 5626, which expands the possibility of using specific data of manufacturers and sizing of facilities. In this context, the present work proposed a comparative study of the sizing methodologies of the hydraulic installations of cold water installed in a hospital located in Belém do Pará, according to the update of NBR 5626/2020 building systems of cold water and hot water - design, execution, operation and maintenance that cancels and replaces NBR 5626/1998 cold water building facilities. Thus, the research was divided into step (1) bibliographic research, presentation of the study area and data collection, step (2) dimensioning of the cold water system considering nbr 5626/98, step (3): sizing of the cold water system considering NBR 5626/20 and step (4) analysis of the results. In general, with this case study, a practical approach was obtained to apply the updated parameters of the NBR 5626/2020 regulation in relation to NBR 5626/1998, presenting flow values, determined by the specific information of each sanitary piece, where we had an increase in this parameter, as to the diameter we had in most of the preumadas the decrease directly interfering in the load loss that increased and how much available pressure a decrease.
