Abstract

Predmet ovog diplomskog rada je projektno rješenje sustava grijanja zraka, pripreme potrošne tople vode i grijanja bazenske vode za zgradu na području grada Zagreba prema zadanoj arhitektonskoj podlozi. Ukupna korisna površina zgrade iznosi 6315 m2. Proračun toplinskih gubitaka zgrade proveden je prema normi HRN EN 12831.
Sportske dvorane sa bazenima su javne ustanove u kojima osim zaposlenika borave ljudi različitih životnih dobi i zbog toga je važno ispravno dimenzionirati sustav grijanja zbog stvaranja toplinske ugodnosti.
Izvor topline za sustave grijanja zraka je toplinska podstanica. Kao ogrjevna tijela koriste se podno i toplozračno grijanje te su dimenzionirani na temelju prethodno određenih gubitaka zgrade. Važno je održavati unutarnju projektnu temperaturu zraka od 28oC i relativnu vlažnost od 60 %. Za sustav grijanja bazenske vode koristi se toplinska podstanica kao primarni izvor topline i pločasti sunčevi kolektori kao pomoćni izvor. Toplinski gubici bazenske vode javljaju se zbog ishlapljivanja vode, provođenja kroz oplošje bazena i dodavanja svježe vode. Potrebno je održavati temperaturu bazenske vode na 26 oC. Za pripremu potrošne tople vode koristi se akumulacijski sustav sa bivalentnim spremnikom koji se zagrijava solarnim kolektorima, uz podršku toplinske podstanice. Kolektorska polja smještena su na ravnom krovu zgrade pod nagibom od 30o prema jugoistoku.
Odabrane komponente sustava povezuju se u funkcionalnu cjelinu sa odgovarajućim regulacijskim elementima za potpuno automatski rad kako bi korištenje sustava bilo što jednostavnije za korisnike. Smještanje opreme predviđeno je u podrumu.

Abstract (english)

The subject of this graduate thesis is the project solution of the heating system, preparation of hot water and heating of the pool water for the building in the city of Zagreb according to the given architectural background. The total usable area of the building is 6315 m2. Calculation of heat losses of buildings was carried out according to HRN EN 12831.
Swimming pool sports halls are public facilities where except emlpoyees are people of different ages, and it is therefore important to properly dimension the heating system to create warmth.
The source of heat for air heating systems is the thermal substation. As heating elements, floor and air heating are used and are dimensioned based on pre-determined building losses. It is important to maintain an internal projected temperature of 28oC and a relative humidity of 60%. For the pool water heating system, the thermal substation is used as the primary heat source and the plate solar collectors as the auxiliary source. Pool water losses are due to the evaporation of water, through swimming pools and adding fresh water. It is necessary to maintain the pool water temperature at 26 oC. For storage of hot water, a storage system with a bivalent tank that is heated by solar collectors is used, with the support of a thermal substation. The collector fields are located on a flat roof of a building with a slope of 30 degrees to the southeast.
The selected system components are connected to a functional unit with the appropriate control elements for a fully automatic operation to make the use of the system as easy as possible for the users. The equipment is provided in the basement.
