Abstract:Sesalni akumulator je ključni element raziskave v diplomskem delu. Element se nahaja v hladilnem sistemu za uparjalnikom. Obravnavan problem zajema zamenjavo bakrenega akumulatorja z drugim, ki bo cenovno ugodnejši in bo prav tako izpolnjeval enake tehnične karakteristike kot predhodna izvedba. Problem bakrenega akumulatorja se pojavi pri spoju z aluminijasto cevjo, kjer zaradi neustrezne obdelave površine na spoju prihaja do puščanja. Pri iskanju najugodnejše rešitve sem si pomagal s tabelo virov. V okviru eksperimentalnega dela so bila izvedena mehanska testiranja, testiranja notranje vlage ter nečistoč, slana komora in analiza poroznosti spoja. Ugotoviti je bilo potrebno tudi ustrezen način spajanja ter izvesti stroškovno analizo. Izmed vseh rešitev se je kot najprimernejši izkazal aluminijast akumulator, ki ga v sistem spojimo s postopkom lotanja. Zamenjava akumulatorja omogoča večje prihranke ter zmanjšanje zastojev v proizvodnem procesu.
Keywords:hladilni sistem, zamenjava sesalnega akumulatorja, tehnologija spajanja, izbira ustreznega materiala, mehansko testiranje, izračun stroškov, ovrednotenje izbrane rešitve.

Title:Tecnological and cost analysis of introducing the suction accumulator in the cooling system
Abstract:Suction accumulator is the key element of the research in the thesis. The element is located in the cooling system behind the evaporator. This issue deals with the replacement of the copper suction accumulator with another, which will be cheaper and will also meet the same characteristics as the previous one. The problem with the copper accumulator occurs in the junction between the accumulator and the aluminium tube. Due to the inadequate treatment of the surface there can be some leakage in the junction. In the search for the best solution I have helped myself with the table of the resources. Experimental work included mechanical testing, testing of internal moisture and impurities, salt chamber testing and analysis of porosity in the joint. I also had to find a suitable way of fusing and carry out a cost analysis. Aluminium accumulator proved to be the most suitable solution and can be added in the cooling system with the process of soldering. The replacement of the suction accumulator is economical and reduces congestions in the manufacturing process.
Keywords:cooling system, replacement of the suction accumulator, merge technology, selection of appropriate materials, mechanical testing, calculation of expenses, evaluation of selected solution.
