Ideja izrade diplomskog rada jest konstruirati edukacijski model hladnjaka na kojemu će studenti moći proučavati princip rada rashladnog stroja te na taj način lakše razumjeti teorijski dio termodinamike. Diplomski rad sastoji se od dva dijela. U prvom dijelu rada opisani su termodinamički procesi i zakoni na kojima se temelji rad rashladnih strojeva. Nakon toga opisan je i princip rada hladnjaka, nabrojani su i opisani elementi koji su potrebni za rashladni proces. Drugi dio je eksperimentalni. Opisan je postupak izrade modela hladnjaka. Nabrojane su faze i postupci konstrukcije. Opisan je postupak baždarenja tlaka i temperature te postavljeni rezultati jednog od mjerenja.The idea of making a diploma thesis is to construct an educational model of a refrigerator on which students will be able to study the principle of operation of a refrigeration machine and thus more easily understand the theoretical part of thermodynamics. The thesis consists of two parts. The first part of the paper describes the thermodynamic processes and laws on which the operation of refrigeration machines is based. After that, the principle of operation of the refrigerator is described, the elements required for the cooling process are listed and described. The second part is experimental. The process of making a refrigerator model is described. The phases and procedures of construction are listed. The procedure of pressure and temperature calibration is described and the results of one of the measurements are set
