Power accumulation from renewable energy sources
Kratschmer, Bruno ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
In this thesis I deal with problem of power acumulation from renewable energy sources. First part present the available technologies used for power accumulation. In the second part is designed the systém of acumulation in compressed air with a transformation electric output 1 MW, when is used made elektricity from wind-power plant. In the third part is an assessment in terms of both technical and economic comparison with the use of electicity from the network.

Ventilation and heating of an industrial building
Švábenský, Jiří ; Charvát, Pavel (referee) ; Krejčí, Vladimír (advisor)
The goal of this diploma thesis is suggest solution of ventilation and heating of industrial building. The solution is primarily based on calculation of thermal losses and thermal gains of the building. The project deals with supply of air for individual parts of construction in summer and winter. The solution consist of proposal of ducting and calculation of air handling units and unit heaters. The system of ventilation and heating is process in drawing documentation.

Computational tool for design of heat storage tank filled with phase change material
Duška, Michal ; Hrubý, Jan
The report presents an outcome of a contractual research carried out for JABLOTRON ALARMS a.s.. Mathematical models solving the problems defined by the contract as "Design calculation of heat storage tank filled with PCM encapsulated in approximately spherical capsules..." and "Design calculation of rod heating element in water tank with forced convection" (later changed on natural convection) are described in chapter 1. An implementation of the mathematical models into the Microsoft Excel spreadsheet with use of VBA is presented in chapter 2. The computational tools were handed over to the contractor on time. Alternative PCM for heat storage, especially materials based on paraffin waxes, and also additives to improve thermal conductivity and other properties are discussed in chapter 3.
