Abstract:V magistrskem delu je opisan postopek preračuna sklopa kapilare in sesalne cevi v hladilnem sistemu, ki skupaj tvorita prenosnik toplote, da bi ugotovili, kakšen je vpliv preseka kapilare na delovanje hladilnega sistema. Preračunana sta padec tlaka in sprememba temperature s tremi različnimi kapilarami, ki so nameščene na istem hladilnem sistemu, saj nas zanima sprememba učinkovitosti pri prenosu toplote iz kapilare na sesalno cev, ko spremenimo presek kapilare. Preračun je podprt z eksperimentalnimi meritvami. Vključene so še meritve ostalih komponent hladilnega sistema, da smo lahko skupno ovrednotili, kako vpliva presek na delovanje sistema. Izsledki tega dela so, da je prenosnik toplote učinkovitejši z večjim notranjim premerom kapilare, saj je površina prenosa tako večja, posledično je zato tudi učinkovitost hladilnega sistema boljša z večjim notranjim premerom kapilare pri enaki dolžini prenosnika.

Title:Expansion element and the impact of its cross-section on the refrigeration cycle in refrigeration appliances
Abstract:This master's thesis describes the procedures for calculating the capillary tube and suction tube assembly in a cooling system, which together form a heat exchanger, in order to determine the influence of the capillary cross-section on the operation of the cooling system. The pressure drop and temperature change with three different capillary tubes installed on the same cooling system are calculated, since we are interested in the change in efficiency in heat transfer from the capillary to the suction tube when the capillary cross-section is changed. The calculation is supported with experimental measurements. Measurements of other components of the cooling system are also included, so that we can collectively evaluate how the cross-section affects the system. The results of this work are that the heat exchanger is more efficient with a larger inner diameter of the capillary tube, since the transfer surface is thus larger, and consequently the efficiency of the cooling system is also better with a larger inner diamater of the capillary tube fort he same lenght of the heat exchanger.
Keywords:expansion element, refrigeration cycle, refrigeration appliance, pressure drop, heat exchange, Gorenje d.o.o.
