Abstract

Diplomski rad izrađen je na temu grijanja i hlađenja obiteljske kuće nulte emisije korisne površine 382 m2 koja se nalazi na području Dalmacije. Na početku rada analizirana je fizika zgrade, proračunato je toplinsko i rashladno opterećenje obiteljske kuće prema normama HRN EN 12831 i VDI 2078 te izračunata godišnja potrebna toplinska energija za grijanje i hlađenje prema normi HRN EN 13790.
Standard nulte emisije obiteljske kuće, ostvaren je ugradnjom fotonaponskog sustava za proizvodnju električne energije te dizalice topline zrak – voda kao sustava za potrebe toplinske energije. U drugom dijelu rada dimenzionirana je dizalica topline. Dimenzioniranje dizalice topline uključuje određivanje i izračun procesa u režimima grijanja i hlađenja te prema izračunatim vrijednostima se proračunavaju izmjenjivači topline, cjevovod i cirkulacijska pumpa. Na kraju je izrađena shema spajanja termotehničkih sustava i izometrijski prikaz dispozicije elemenata dizalice topline pomoću CAD softverskih alata.

Abstract (english)

The master's thesis analyses heating and cooling of a zero-emission family house with a useful area of 382 m2 located in the Dalmatia region. In the first part of the thesis the building physics is analysed, and the thermal and cooling loads of the family house are calculated according to the HRN EN 12831 and VDI 2078 standards. Additionally, the annual required thermal energy for heating and cooling is computed in accordance with the HRN EN 13790 standard.
The zero-emission standard for the family house is achieved through the installation of a photovoltaic system for electricity production and an air-to-water heat pump as a system for thermal energy needs. The second part of the thesis is focused on the heat pump sizing. The sizing process involves determining and calculating the processes in heating and cooling modes. Based on the calculated values, heat exchangers, pipelines, and circulation pump are calculated and sized. Finally, a scheme connecting the thermo-technical systems and an isometric representation of the disposition of heat pump elements are designed through CAD software tools.
