Thermodynamics of ideal gases in Matlab
Zábojník, Jakub ; Klimeš, Lubomír (referee) ; Štětina, Josef (advisor)
In terms of bachelor’s thesis a toolbox of functions for basic computing in thermodynamics with ideal gases and their mixtures was built in environment of computer program MATLAB. Source code of these functions and their description are parts of this thesis. Among others fundamental characteristics of thermodynamic values and terms on which the creation of functions was built, and instruction for calling of functions are mentioned here. Functions in toolbox imaginary are divided to some groups. This dividing is results from principle of thermodynamic calculation. Functions from two neighbouring groups are directly tied together. For lucidity of function sequences and for functions usage and toolbox explanation the examples of using functions examples of functions usage in specific thermodynamic calculations.

HAM-Tools library use for the simulation of the thermal performance of the house
Zábojník, Jakub ; Charvát, Pavel (referee) ; Štětina, Josef (advisor)
In terms of master’s thesis HAM-Tools library designed for MATLAB/Simulink was modified for the use in simulations of houses in the Czech Republic. Modified library and its parts were described in detail and tested by the simulation of the one-zone and two-zones models of the house. The simulations of models with same parameters were also realized in program TRNSYS. The corresponding results achieved in mentioned simulation tools were compared to each other. The one-zone model created by using HAM-Tools library is tested by the simulation of ventilating, heating, cooling, and sources of moisture. A demonstration of the practical use of the simulation is carried out in the thesis, namely by examining the influence of the insulation thickness on the thermal performance of the house (resp. its heat loss) on real atmospheric conditions. Among others, available resources of meteorological data are mentioned and compared to each other. The function for processing of the meteorological data to a file compatible with the HAM-Tools library was created. It was also created a material data file containing commonly used materials of building structures in the Czech Republic and their parameters.
