Proposal heating system of the house
Minařík, Petr ; Hrnčířová, Michaela (referee) ; Baláš, Marek (advisor)
This work includes the calculation of heat loss and design of the house heating system. To determine the heat loss of the family home will be used standard ČSN EN 12831. Heat loss will be calculated for each room. Radiators are designed to individual rooms for different temperature gradients and by heat losses. The lounge is designed underfloor heating. For heating are designed three different heat sources. One source of high-temperature and low-temperature two sources. The investment costs of the heating system will be evaluated finally.

Ventilation and heating in a retrofitted two-story family house
Minařík, Petr ; Štětina, Josef (referee) ; Charvát, Pavel (advisor)
The thesis deals with the calculation of the design heat load of a reconstructed family house and the design of both the space heating system and the balanced ventilation system for the house. The determination of the design heat load was performed according to ČSN EN 12831 technical standard. A low-temperature hydronic heating system was chosen for space heating of the house. The thesis describes the design of the system including calculations and the technical drawings. A heat source for the heating system was chosen with regard to the requirements of the investor. A mechanical ventilation system with heat recovery was proposed for house ventilation. The thesis contains the design of the ventilation system including calculations and the technical drawings.

Návrh strategie pro rozvoj informačního webu
Minařík, Petr
The bachelor thesis „Design of a strategy for the development of the information website“ is focused on the solution of the issue of the web site www.verejne- brusleni.info, both from a technological and marketing point of view, as well as from a strategic point of view. The main objective of the work is to focus on various types of analysis of current activities in order to create a new strategy and recom- mendations for successful development and long-term sustainability of the „Veřejné bruslení“ project.

Ovlivnění výnosu a kvality pšenice ozimé použitím stabilizovaných dusíkatých hnojiv se sírou
Minařík, Petr
This thesis examined the effects of applied stabilized nitrogenous fertilizers with sulphur (ENSIN and ENTEC 26) and nitrogenous fertilizers without inhibitors (DASA) in the nutrition of winter wheat. The effect of various forms of stabilized nitrogenous fertilizers on the yield and qualitative parameters of winter wheat was studied during a three-year vegetative experiment. The experiment was carried out in the form of a small plot experiment in two localities (Žabčice near Brna and Vatín near Žďáru nad Sázavou). The experiment included the following six variants of fertilisation: 1. unfertilised control, 2. DASA + DASA (ammonium nitrate and ammonium sulphate) , 3. ENSIN, 4. ENTEC 26, 5. LAD (ammonium nitrate with dolomite) + ENSIN, 6. LAD + ENTEC 26. On all fertilized variants there was a significant increase in yeald compared to the unfertilized control (an average of 22.4 to 37.3 %). The highest average yield for three years amounted variant LAD + ENSIN in the locality Vatín and Žabčice. The maximum average yield 7,39 t/ha reached the option LAD + ENSIN in the locality Vatín and 7,61 t/ha in the locality Žabčice. This variant also achieved the highest content of N - substances and sedimentation value. Only in bulk density was better option LAD + ENTEC 26, however, there was no significant difference. Variant LAD + ENSIN was effective also in terms of economic efficiency.

Dusíkato-sirná hnojiva s inhibitory nitrifikace ve výživě pšenice ozimé
Minařík, Petr
This work examines the influence of nitrogen-sulfur fertilisers with nitrification inhibitors in winter wheat nutrition. We esteblished small-plot experiment in the test-field station of School Farm in Žabčice near Brno in the agricultural year 2012/2013. The experiment included six variants of fertilisation: 1. unfertilised control, 2. ENSIN 100% (DASA with inhibitor nitrification), 3. ENSIN 80%, 4. ENTEC 26 100%, 5. ENTEC 26 80%, 6. DASA + DASA (ammonium nitrate + ammonium sulfur). Fertilisers with inhibitors were applied in the stage of tillering at dose 140 kg nitrogen per ha, respectively, 120 kg nitrogen per ha for the variant with 80% of the dose. DASA fertiliser was applied in two divided doses. We evaluated the effect of fertilisation on the yield and the grain quality parameters. Statistically significant was the effect of fertilised variant to N-tester. The highest results were obtained for variant DASA + DASA. Fertilisation was not significant influence for yield and grain volume, but the highest yield and grain volume was achieved in variant ENTEC 26 80%. The fertilisation has statistically significant effect on content of N-substances in the grain. The highest average content of N-substances reached variant DASA + DASA, which has 28% higher N substances content compared to unfertilised variant. Between gluten content and sedimentation value in the fertilised variant were found significant differences. The highest gluten content and sedimentation value were found in variant DASA + DASA.
