Abstract
Dizalice topline su uređaji koji na principu ljevokretnog kružnog procesa dovode energiju s niže temperaturne razine na višu uz pomoćnog prikladne radne tvari te mogu poslužiti kao izvor toplinskog i rashladnog učinka u termotehniĉkim sustavima. Dizalice topline ubrajaju se u sustave koji rade s obnovljivim izvorima topline (zrak, zemlja, voda) i zato su znatno učinkovitije i ekološki prihvatljivije od sustava grijanja na fosilna goriva. Na uĉinkovitost dizalice topline utječu termodinamički parametri njenih pojedinih dijelova, dakle kompresora, kondenzatora, prigušnog ventila i isparivača. U ovom završnom radu ispitan je utjecaj temperature kondenzacije i efikasnosti kompresora na učinkovitost sustava. Proračun je proveden pomoću programskog paketa EES koji se koristi za numeričko modeliranje termodinamičkog sustava, optimizaciju procesa te za izradu procesnih dijagrama. Također je provedena usporedba različitih radnih tvari koje se koriste kao radna sredstva u dizalicama topline.
Abstract (english)
A heat pump is a device that is able to transfer heat from one fluid at a lower temperature to another at a higher temperature and can serve as a source of heat energy and cooling energy in HVAC systems. Heat pumps are systems that work with renewable energy (air, ground, water) and therefore are much more efficient and more environmentally friendly than fossil fuels heating systems. Efficiency of heat pumps is mostly influenced by thermodynamic parameters of its individual parts, compressor, condenser, expansion valve and evaporator. Effect of condensing temperature and also effect of efficiency of compressor on heat pump efficiency is examined in this project task. The calculation was conducted in the software package EES that is used for numerical modeling of complex mathematical equations, process optimization and production of process diagrams. Also, comparison of different refrigerants that are used in heat pumps, was conducted.
