Abstract
U ovom završnom radu smo opisali što su to dizalice topline, kako one rade, na koje kategorije se dijele i na kraju smo jednu dizalicu topline ubacili u stvarni sustav. Krenuli smo od ljevokretnog termodinamičkog sustava koji je osnova na kojoj se temelji rad svih dizalica topline. Zatim smo nabrojali sve važne dijelove bitne za rad dizalice topline: radni medij, kompresor, kondenzator, ekspanzivni ventili i isparivač, te smo pomno objasnili njihovu pojedinačnu svrhu u samom radu dizalica topline. Podijelili smo dizalice topline prema vrsti medija od kojih preuzimaju toplinsku energiju: zrak, voda, tlo i kojima predaju toplinsku energiju: zrak i voda. Zatim smo nabrojali sustave u kojima se primjenjuju dizalice topline i pojasnili smo kako su dizalice topline bolje i efikasnije od ostalih sustava za grijanja i hlađenje medija koji se najčešće koriste za grijanje i hlađenje prostora u kojima ljudi borave. Na kraju smo odabrali jedan sustav u obiteljskoj kući, proračunali gubitke energije i potrebnu snagu za grijanje i hlađenje odabranog prostora te odabrali dizalicu topline prikladnu za to.
Abstract (english)
In this final thesis, we described what heat pumps are, how they work, what categories they are divided into, and finally we inserted one heat pump into the real system. We started from the left-handed thermodynamic system, which is the basis on which the operation of all heat pumps is based. Then we listed the important parts essential for the operation of the heat pump: working medium, compressor, condenser, expansion valves and evaporator, and we carefully explained their individual purpose in the operation of the heat pump itself. We have divided the heat pumps according to the type of media from which they take thermal energy: air, water, soil and to which they transfer thermal energy: air and water. Then we listed the systems in which heat pumps are used and we explained how heat pumps are better and more efficient than other systems for heating and cooling media that are most often used for heating and cooling spaces where people stay. In the end, we chose one system in the family house, calculated the energy losses and the required power for heating and cooling the selected space, and chose the heat pump suitable for it.
