Abstract
Ovim završnim radom dan je osvrt na važnost pitke vode te zahtjevima i problematikom projektiranja instalacija pitke vode. Dan je kratki uvod u važeće standarde i zakone koje pitka voda mora zadovoljiti kao i naglasak na mikrobiološku kvalitetu vode. U pogledu mikrobiološke kvalitete se najčešće ističe moguća pojava legionele pneumophile te koraci i upute za sprječavanje širenja iste. Kako bi se očuvala propisana kakvoća pitke vode predstavljena su tri osnovna područja projektiranja instalacije pitke vode koja osiguravaju ispunjenje zahtjeva kvalitete vode, a to su: temperatura, izmjena vode i protok. Osim navedenih osnovnih područja dan je osvrt i na korištene materijale kao i prijedloge spajanja izljevnih mjesta te vođenja cjevovoda. Nakon upoznavanja sa zahtjevima projektiranja cjevovoda u vidu postizanja kvalitete pitke vode prikazan je postupak dimenzioniranja cjevovoda prema standardu DIN 1988-300. Poznavanjem postupka dimenzioniranja te zahtjeva za kvalitetu pitke vode, izrađeno je idejno rješenje modela kojim će se vršiti ispitivanje pada tlaka u cjevovodu. Navedeni model predstavlja primjer tipične kupaonske cijevne instalacije. Sam model sastoji se od stalnog i promjenjivog dijela cjevovoda kako bi se mogao simulirati proizvoljan raspored i promjer cijevi, odabir različitih izljevnih mjesta te utjecaj istih na izmjereni pad tlaka u cjevovodu. Mjerenje će se vršiti pomoću digitalnih mjerača protoka te manometara koji su postavljeni na odabranim točkama u cjevovodu. Svi elementi modela su pobliže prikazani i opisani kao i problematika izrade i spajanja samog modela.
Abstract (english)
This paper gives a review on importance of drinking water and the requirements and difficulties faced while designing the installations of drinking water. A short introduction is given on current drinking water standards and laws, as well as an emphasis on microbiological quality of water. In terms of microbiological quality of water most common topic mentioned is the possible of growth and spread of Legionella pneumophila as well as steps and instructions in preventing it. In order to preserve the required quality of water, an overview of three main areas is given; temperature, water exchange and water flow. Apart from the main areas mentioned, an overview is also given on materials used as well as recommendations on connecting taps and pipes layout. After an introduction on pipe sizing procedure, water quality design requirements are presented according to DIN 1988-300. Knowing the pipe sizing procedure, as well as water quality requirements, a concept solution of a model used for measuring water pressure drop in drinking water systems is shown. The model represents a typical bathroom pipe installation. It consists of a fixed and modular section in order to simulate an interchangeable pipe diameter and layout, as well as different tap choices, in order to show the influence of given changes on the measured pressured drop. Measurement will be done by digital flow meters as well as pressure gauges, which are set on selected points of the model pipeline. All parts of the model are presented and described, as well as common issues faced while assembling the model.
