Heat pump efficiency analysis

Analiza učinkovitosti toplotne črpalke opisuje, kako efektivno sistem deluje. Namen tega dela je odgovoriti na vprašanja, koliko je možno privarčevati in ali se splača vložiti v nabavo toplotne črpalke. Sodobne toplotne črpalke, v primerjavi s klasičnimi sistemi ogrevanja na fosilna goriva, lahko zmanjšajo dejansko porabo energije tudi do 75%. Pri tem je pomembna visoka učinkovitost sistema, zlasti pravilno izbrane in vgrajene komponente ter optimalno nastavljen ogrevalni sistem in oprema za regulacijo. Posebno pozornost je potrebno nameniti napakam v procesu dimenzioniranja, izbire in vgradnje komponent ter nastavitve in načina obratovanja opreme. Primerjava klasičnega sistema ogrevanja na utekočinjen naftni plin (UNP) in toplotne črpalke na osnovi analize dejanske porabe energije je pokazala, da učinkovitost toplotne črpalke znatno zniža stroške ogrevanja in upravičuje investicijo, kljub finančni naložbi v tovrstno opremo. Ne smemo pa zanemariti izrazito večjo prijaznost do našega okolja kot bilo kateri drugi sistem s fosilnim virom energije, kar pa ni predmet tega dela.The heat pump analysis is intended to show, how efficient the system operates. The key points of this work are potential savings and whether it is reasonable to invest in the installation of a heat pump. Modern heat pumps could reduce the energy consumption, compared to conventional heating systems using fossil fuel, up to 75%. Certainly, high system efficiency is necessary, in particular properly selected and installed components, as well as an accurately designed heating system with optimized control. Special attention needs to be paid on potential mistakes in the entire process of designing, selection, installation, up to the parameter settings and desired mode of operation. The comparison of a liquid petrol gas (LPG) heating system and a heat pump using the consumption analysis with real measurement data, has shown, that the efficiency of the heat pump significantly reduces costs of heating and justifies the investment in such a system. Without neglecting, that this system is markedly friendlier to the environment than any other system using fossil resources, but this is not the subject of this work
