Abstract

U sklopu diplomskog rada obrađena je tematika hidraulike sustava grijanja na teoretskoj i analitičkoj razini. Kroz teoretska poglavlja obrađen je pojam uravnoteženja sustava grijanja s primjerima postizanja istog. Opisane su hidrauličke karakteristike komponenti sustava te je pojašnjen pojam autoriteta ventila. Teoretski dio rada završava poglavljem o cirkulacijskim pumpama i pripadajućim europskim direktivama. Za potrebe numeričke analize modeliran je
sustav grijanja s generatorom topline, cirkulacijskom pumpom, cijevnim razvodom termostatskim regulacijskim ventilima, automatskim balans ventilima i ogrjevnim tijelima. Numerička analiza provedena je Hardy Cross metodom za svaki sat u godini. Rezultatima numeričke analize i interpretacijom rezultata zaključuje se diplomski rad.

Abstract (english)

The thesis deals with the topic of hydraulics of the heating system at theoretical and analytical level. Through the theoretical chapters the notion of balancing the heating system with examples of achieving it has been covered. The hydraulic characteristics of the system components are described and the concept of valve authority is clarified. The theoretical part of the thesis ends with a chapter on circulation pumps and associated European directives. For the purposes of numerical analysis, a heating system with a heat generator, circulation pump, pipework, thermostatic regulating valves, automatic balancing valves and heating elements was
modeled. Numerical analysis was performed using the Hardy Cross method for each hour of the year. The results of numerical analysis and interpretation of the results conclude the thesis.
