Abstract (Croatian)

U sklopu ovog rada formiran je numerički model cijevne mreže jednostavnog sustava toplovodnog grijanja te je pomodu Hardy Cross metode provdena simulacija rada za različita pogonska stanja. Sustav je zasebno promatran za hidrauličko nebalansirano i balansirano stanje, pri čemu su u oba slučaja korištene četiri različite metode upravljanja cirkulacijskom pumpom, a zatim i uspoređeni rezultati. S posebnim su interesom u ovom radu promatrani parametri autoriteta ventila i pogonskih karakteristika ventila, čiji su rezultati također uspoređeni za spomenute izvedbe promatranog sustava.

Abstract

The subject of this master's thesis is developing a numerical model of a hot-water heating system pipe network, which is used to simulate different operating conditions, by using the Hardy Cross method. The system is analyzed separately for hydronic unbalanced and balanced conditions, also for both cases 4 different circulator pump control methods are applied. Results are then compared, with special emphasis on valve authority and operational valve characteristics.
