Abstract

U ovom Diplomskom radu detaljno je opisana izrada i rezultati simulacije sustava grijanja s dizalicom topline, koja koristi tlo kao toplinski spremnik, u računalnom programu TRNSYS. Dizalica topline toplinsku energiju s tlom izmjenjuje pomoću bušotinskog izmjenjivača topline (u daljnjem tekstu: BIT). Svojstva tla i BIT-a preuzeta su iz rada „Eksperimentalno i numeričko određivanje toplinskih svojstava tla za geotermalne dizalice topline“ [2] u kojem je opisano provedeno mjerenje i računalna simulacija toplinskog odziva tla na lokaciji Fakulteta strojarstva i brodogradnje. U Diplomskom radu analiziran je utjecaj toplinske provodnosti tla, toplinske provodnosti ispune bušotine, volumena spremnika za vodu te režima grijanja na toplinski množitelj (COP) dizalice topline.

Abstract (english)

This Master Thesis contains detailed description of ground source heat pump heating system modelling in TRNSYS. Heat pump gathers heat energy from the ground using borehole heat exchangers (BHE). Ground and BHE parameters are taken over from „Eksperimentalno i numeričko određivanje toplinskih svojstava tla za geotermalne dizalice topline“ [2], in which conducted thermal response test and its computer simulation in TRNSYS are described. BHE’s location is at the site of Faculty of Mechanical Engineering and Naval Architecture in Zagreb. Ground’s and heat pump system’s parameters impact on heat pump’s COP is analyzed in this work, respectively: ground thermal conductivity, borehole filling thermal conductivity, water storage tank volume and heating temperature regime.
