Timofejevas, Andrius 28 June 2010 (has links)
Darbe nagrinėjama visuomeninio pastato vėsinimo sistema. Pastatas, kurio naudingas plotas 7900 m2, yra Vilniaus mieste, jo vėsinimo sistemoje yra 268 ventiliatoriniai konvektoriai. Pasirinkti trys šių įrenginių hidraulinio aprišimo variantai: pastoviojo srauto sistema, kintamojo srauto sistema su rankiniais balansavimo ventiliais ir kintamojo srauto sistema su automatiniais balansavimo ir valdymo ventiliais. Lyginamos pradinės sistemų investicijos ir montavimo bei eksploatacijos išlaidos. / An issue is a cooling systems analysis in a public building.
