Abstract:Magistrska naloga opredeljuje ključne dejavnike učinkovite rabe energije pri izbiri klimatizacijskega sistema. V začetni fazi načrtovanja in izbire ustreznega sistema je pomembna analiza vplivov klimatizacijskih pogojev. Pomemben vpliv imajo zunanji dejavniki, klimatski dejavniki, karakteristika objekta in letni režim delovanja sistema. Ogrevanje, hlajenje in prezračevanje objektov so področja, kjer ob ustreznem načrtovanju in izbiri ustreznih energentov in sistemov dosežemo prihranke energije, kar je eno izmed vodil trajnostnega razvoja učinkovite rabe energije. Teoretične osnove prezračevanja in klimatizacijskih sistemov rekuperativne oziroma regenerativne stopnje vračanja odpadne toplotne energije predstavljajo vodilo ekonomske ocene pri izbiri sistema. Na podlagi raziskav in analitskega dela so podatki primerljivi z teoretičnimi osnovami. Preračun hladilnih obremenitev, notranje in zunanje hladilne obremenitve je bil opravljen na podlagi podatkov določenih klimatizacijskih parametrov in lastnosti karakteristike objekta. Količina in stanje dovodnega zraka je odvisno od suhe hladine obremenitve, maksimalne količine zraka na osebo in količina potrebe dovedenega zraka glede na število izmenjav v eni uri. Na podlagi opravljene analize in aplikativnega dela je podana izbira ustreznega klimatizacijskega sistema. Ekonomski aspekti predstavljajo nalogo planiranja in načrtovanja klimatizacijskih sistemov učinkovite rabe energije in pri izbiri ustreznega sistema v primerjavi več sistemov nudijio prihranke energije. Narejena je primerjalna analiza osnovnega sistema, ki ne podaja vračanja odpadne toplote v primerjavi z sistemoma rekuperacije in regeneracije. Sistem rekuperacije je proces, pri katerem poteka vračanje odpadne toplote, sistem regeneracije je proces, pri katerem poteka vračanje odpadne toplote z ustreznim vlaženjem zraka. Osnovni klimatizacijski sistem v primerjavi rekuperativnim in regenerativnim sistemom ima nižji prihranek energije. Naravno prezračevanje predstavlja največje izgube v primerjavi s različnimi klimatizacijskimi sistemi, vračanja odpadne toplote v povprečju 10 - 40%. Analize in raziskave potrjujejo, da je izbira ustreznega sistema pri novogradnjah oziroma pri adaptacijah pomembna in ima veliko vlogo pri prihrankih energije, kar je vodilo učinkovite rabe energije in trajnostnega razvoja.

Title:EFFICIENT USE OF ENERGY IN AIR-CONDITIONING
Abstract:Master thesis identifies the main factors of the efficient use of energy in air condition systems. In the initial phase of project planning to select the appropriate air condition system it is important to procced the analysis evaluation of air condition parameters, which influence on functionality of the air condition systems. The important aspects have external factors of the climatic condition, buildings characteristics and operating period. The appropriate heating, cooling and ventilation processes in the buildings with suitable energetic sources lead to energy savings as an important aspect of sustainable development of the efficient use of energy in the air condition systems. The theoretical thesis of ventilation, air condition systems with recuperative or regenerative waste heat processes tend as important evaluation of economic analysis. Based on research and analytical aspects, the data are comparable to theoretical thesis. The calculation of cooling load, dry cooling load and dump cooling load was done based on data determined by climatic parameters and buildings characteristics. The amount of input air depend on more criteria as dry cooling load, maximal amount of fresh air per person and number of exchanges in one hour. Air condition systems are selected based on results of applicative task. The economic aspects are task of planning and designing the air condition systems and take selection between more systems to compare the efficiency and savings. Comparable analysis of three different type air condition system proceeded with different degrees of efficient use of energy and recycling waste heat, basic system without heat recuperation, air condition system with recuperation process and air condition system with regenerative heat treatment. The recuperation systems is the procedure of waste heat recycling, regeneration is the method of waste heat recycling energy, that transfers heat and dump. Basic air condition systems without waste heat recycling comparing to recuperation and regeneration system estimated lower energy savings. Natural ventilation present the highest energy loss in 10-40 % compared with the different air condition system types of waste heat recuperation. Analysis and research confirmed, that selection of the appropriate air condition system in new buildings and adaptation buildings have important aspect of energy savings, which is a guide of the efficient use of energy and sustainable development.
Keywords:Efficient use of energy, energetics, air condition systems, recuperation, regeneration, economic analysis
