Abstract

U sklopu ovog diplomskog rada napravljen je dinamički model jednostavnog rashladnog sustava u programskom jeziku MATLAB.
U prvom poglavlju opisan je način rada rashladnog sustava i navedene su opće energijske postavke koje omogućuju njegovu realizaciju. Također su definirani i parametri o kojima ovisi njegova efikasnost.
U drugom poglavlju dani su izvodi svih jednadžbi koje su korištene u simulaciji i opisani su parametri o kojima ovisi dinamika termoekspanzijskog ventila, isparivača i stapnog kompresora. Dinamika kondenzatora nije opisana.
Treće poglavlje daje opis algoritma simulacije, sadrži geometrijske karakteristike termoekspanzijskog ventila, isparivača i stapnog kompresora i daje prikaz i analizu rezultata modela.

Abstract (english)

As part of this graduate thesis, a dynamic model of a simple cooling system was developed in the MATLAB programming language.
First, cooling systems are introduced along with the fundamental principles that make the system possible. Also, coefficient of performance is defined.
In the second chapter, the definition of all the equations used in the simulation are given along with the parameters on which the dynamics of the thermostatic expansion valve, evaporator and reciprocating compressor depend on. Dynamic of the condenser is not given.
Third chapter gives a description of the simulation algorithm, contains the geometric characteristics of the thermostatic expansion valve, the evaporator and the reciprocating compressor, and provides a presentation and analysis of the model results.
