Abstract (Croatian)

U sklopu završnog rada preddiplomskog dijela studija strojarstva provedena je analiza utjecaja napunjenosti rashladnog sustava radnom tvari na radne karakteristike. Analiza je potkrijepljena provedenim eksperimentom u rasponu napunjenosti sustava od 70% do 130%. U prvom dijelu rada je dan pregled radnih karakteristika rashladnih sustava i mogućih načina punjenja sustava radnom tvari. Nakon toga je slijedila analiza podnapunjenosti i prenapunjenosti rashladnih sustava iz literature kojom je pokazan utjecaj na rad i radne karakteristike rashladnih sustava. Zatim je slijedilo provođenje eksperimenta te analiza dobivenih rezultata mjerenja s kojima su se potvrdio utjecaj na radne karakteristike pokazanih iz literature. U prilogu rada se nalazi i shema spajanja i regulacije mjerne linije korištene u eksperimentu.

Abstract

As a part of bachelor's degree thesis in mechanical engineering analysis of the influence of a refrigerant charge on performance of a refrigeration unit has been carried out. Analysis has been supported with the experiment with charge levels ranging from 70% to 130%. In the first part of the thesis were given different performances of a refrigeration unit and different methods of refrigerant charging. Then followed the analysis of undercharge and overcharge of refrigeration units based on the literature from which the influence of a refrigerant charge on performance of a refrigeration unit has been shown. After that, the experiment has been carried out as well as the analysis of results, which confirmed the influence of a refrigerant charge of a refrigeration unit previously described. A scheme of regulation of refrigerant line used for the experiment is in the attachment.
