Diplomsko delo je namenjeno predstavitvi delovanja hladilnega sistema, ki deluje s pomočjo sončne energije na osnovi termoelektričnega pojava, razvoja konceptov in izdelave prototipa takšnega sistema. Iz treh zastavljenih konceptov smo izluščili pomembne faktorje, na temelju katerih smo kasneje izoblikovali dva prototipa. V nalogi smo s pomočjo merilne naprave za shranjevanje podatkov, Ahlborn Almemo 2690-8, izmerili temperaturo različnih mest hladilnega sistema, na katera smo postavili termopare. Na podlagi dobljenih rezultatov smo lahko izračunali zmogljivost izdelanega prototipa in ga primerjal s konvencionalnimi hladilnimi sistemi. Prišel sem do zaključka, da se v našem primeru, kjer je izdelava prototipa termoelektričnega hladilnega sistema, (ki ga poganja sončna energija) sestavljenega izključno iz odpadnih delov, dobljenih v laboratoriju, trenutno ne izplača.

Abstract

Objective of the thesis is to present the working principle of the solar powered thermoelectric cooling system, the development of concepts and prototype making of that cooling system. From three made concepts we took the main ideas and constructed two prototypes. In the thesis we measured the temperature with Ahloborn Almemo 2690-8 data logger's thermocouples which I have placed on different spots of the cooling system. With results of measurements we calculated coefficient of performance of the prototype and then compared the results with the conventional cooling systems, I concluded that in my case, where prototype of solar powered thermoelectric liquid cooling system was made with waste material found in the research laboratory. It is not worthwhile yet.
