20.500.12556/DKUM-22958 RAZVOJ MERILNE PROGE ZA DOLOČANJE KARAKTERISTIK TOPLOTNIH PRENOSNIKOV V LABORATORIJU HZA PODJETJA GORENJE DEVELOPEMENT OF TESTING RIG FOR EVALUATION OF CHARACTERISTIC OF HEAT EXCHANGER IN HZA LABORATORY GORENJE V diplomski nalogi so prikazane primerjalne meritve toplotnih prenosnikov, ki jih uporabljamo v podjetju Gorenje na področju hladilno-zamrzovalnih aparatov HZA. Namen primerjave je potreba po postavitvi merilne proge za določevanje karakteristik toplotnih prenosnikov. Novi način merjenja nam lahko zmanjša stroške pri izdelavi aparatov za testiranje, ob enem pa so meritve hitreje izvedene. V diplomi so opisani sestavni deli hladilniškega sistema, v osrednjem delu pa so prikazani postopki in meritve toplotnih prenosnikov ter dobljeni rezultati. Meritve so se izvajale na kondenzatorjih in uparjalnikih. Postopek merjenja kondenzatorjev in uparjalnikov je bil približno enak, spreminjali so se samo vhodni pogoji. Rezultati meritev z novo metodo so bili primerljivi z obstoječo, kar nam da pozitivno oceno za nadaljnjo uporabo nove metode. The diploma shows comparative measurements of heat exchangers, which are used in Gorenje refrigerators and freezers - HZA. The purpose of comparison is a need to set up the testing rig for determination characteristics of heat exchangers. A new way of measurement can reduce costs for testings refrigerators and the measurements can be faster measured. Diploma describes the cooling system, in the central part are shown the procedures and measurements of heat exchangers with the obtained results. Measurements were carried out in condensers and evaporators. Process of messureing condensers and evaporators were about the same, the differences were in changed input conditions. The measurement results with the new method were comparable to the existing, which gives a positive assessment to use this method. hlajenje hladilni procesi kompresorji prestop in prevod toplote kalorimetrija prenosniki toplote merilna negotovost cooling cooling proces compressors heat convection and conduction calorimetry heat exchangers measurement uncerntaintry true true false [B.
