Cruise ship swimming pool supply and drain system

Tema ovog diplomskog rada svodi se na analizu postojećeg sustava opskrbe i dreniranja bazena na putničkom brodu. Na početku rada vrši se detaljna analiza sustava i opisuje shema opskrbe i dreniranja. Nakon uvodnog predstavljanja sustava, prelazi se na proračun osnovnih hidrauličkih vrijednosti kao što su pad tlaka u cjevovodu, izračun lokalnih gubitaka i određivanje minimalne potrebne snage pumpe, te se dobiveni rezultati uspoređuju sa zadanim parametrima sustava. Uz to se koriste termodinamička znanja kao bi se odredili svi gubici topline u bazenu uzrokovani ishlapljivanjem, konvekcijom i transmisijom. Rezultati pokazuju kako je projektirani sustav uvelike predimenzioniran te da bi se i sa slabijom cirkulacijskom pumpom i manjim kapacitetom izmjenjivača topline, zadovoljili potrebni uvjeti projektiranog bazena. Usporedo sa proračunom, pristupilo se i grafičkom projektiranju sustava pomoću programa za tehničko crtanje i projektiranje, Catia.The topic of this master thesis is an analysis of the existing system of supply and drainage of the swimming pool on the cruise ship. At the beginning of the work, a detailed system analysis is performed and a supply and drain scheme is described. After the introduction of the system, the work is based on the calculation of basic hydraulic values such as pressure drop in the pipeline, calculation of local losses and determination of the minimum required pump power, and they are compared with the default system parameters. Thermodynamic knowledge is also used to determine all heat losses in the pool caused by evaporation, convection and transmission. The results show that the projected system is greatly oversized and that conditions of projected pool would be required even with a poorer circulation pump and lower heat exchanger capacity. Along with the calculation, a graphical design of the system was also approached using technical drawing and designing software, Catia
