Ventilation in sports facility
Frühauf, Patrik ; Šikula, Ondřej (referee) ; Rubinová, Olga (advisor)
The bachelor thesis deals with ventilation in sports facility. The objective of this work is to design two or three air-conditioning units in the part of assigned building. The bachelor thesis is divided into three main parts: theoretical part, calculation part and project.The theme for theoretical part is air distribution. Attention is especially devoted to airflow in a room, piping system and distribution elements. The calculation part is practically focused on designing of air-condition units. The last part of bachelor thesis is formed as documentation for sports facility.

Air conditioning of lecture halls
Vojkůvková, Petra ; Gebauer,, Günter (referee) ; Šikula, Ondřej (advisor)
My thesis deals with evaluation of the current state of microclimatic conditions of problem areas in the L. Jaros Grammar School in Holesov and designing optimal air conditioning. Based on the measurements and simulations of airflow that were carried out, the design includes solution of air regulation and selection of appropriate options to its distribution, which will lead to improvement of thermal-moisture microclimate.

Microclimate and energy balance characteristics of the stands with different management
ERBEN, Jiří
The present thesis deals with the microclimate and energy balance indicators of 2 habitats with different types of vegetation (wetland, pasture) during the growing season. Mainly moisture and temperature regime and energy fluxes were monitored in the period of 1.4. to 30.9., 2014. All values were dependent on the type of vegetation, and the type and location of the environment. Microclimate analysis was performed on two locations - in a pasture in the basin of Mlýnský stream and wetland habitat in the basin of Horský stream. Both sites are located on the right bank of the Lipno lake. All the necessary meteorological characteristics were measured using automatic weather stations. Indicators of temperatures and humidity of soil and air, received, and the total amount of reflected sunlight and heat balance characteristics - albedo, Bowen ratio, evaporative fraction and heat flows were evaluated. The biggest differences were monitored at heights, in which was measured. In terms of relative humidity, values most varied at canopy level, where the differences were noticeable. The highest mean relative humidity was measured at height of 0.2 m and 2 m on the wetland. As relative humidity even air temperature is dependent on the height at which it was measured. While the height of 2 m, the values at both sites was almost identical, at the canopy level are differences significant. The average temperature values depend on the season, but the largest amplitude of the temperature reached the sites in June. The surface temperature of the soil at the wetland was almost unchanged, contrary to pasture its course was similar to air temperatures series at the canopy level. The soil temperature at 20 cm was almost the same at both sites. In terms of energy fluxes, it was found that the highest latent heat flux of evaporation was in wetland. Sensible heat flux was higher in the pasture. The flux of heat into the ground is bigger during the morning and evening hours on the wetland, however ground heat flux was higher in the pasture during the day.

Rebuilding / reconstruction of farm buildings
HORNÁ, Jitka
This bachelor thesis discusses the recontstruction of the particular agrarian object, which serves the animal breeding and is part of the functioning state-owned company MTD Ústrašice. The building is situated near the city Tábor, in the north-western part of the municipality. The goal of this thesis is to accumulate basic knowledge connected to designing agricultural buildings and processing of the technical documentation, which is necessary for the building permit. This thesis is divided into two parts - theory and practice. Theoretical part is focused on the building's influence on the internal microclimate in the stable and on the evaluation of rooms in such buildings. Practical part includes accompanying and technical report and processed design documentation.

Využití poznatků o mikroklimatických poměrech jeskyní
Štěpánková, Lucie
This bachelor thesis deals with the use of knowledge about the cave microclimate conditions. The first part of thesis is a literature review. Review contains major topics such as climate, caves, cave microclimate and monitoring, other studies carried out in caves and research done abroad. Caves microclimate monitoring, being performed both at home and abroad, have recently expanded. The microclimate inside the caves began to change gradually with the increase of tourists. Thanks researches, which takes place inside the caves, it is possible to observe recently changing parameters. Than it is possible to maintain the control through specific measures. There are also topics such as cave biota, bats and lampenflora in the thesis. The thesis concludes characteristics of the area and the Moravian Karst and evaluation of temperature in Catherine Cave

Vliv větrolamů na mikroklimatické poměry okolní krajiny
Xaverová, Pavla
The work is focused on the results evaluating of four measurements of two windbreaks, in spring and autumn. The first one is located approximately 1 km south of Suchá Loz in the Zlín Region, where the measurements took place on 04/18/2007 and 10/20/2007. The second windbreak is located in the South Moravian Region, near the village of Micmanice. The data were measured on 04/04/2007 and 10/12/2006 in these areas. The climatic parameters of air temperature and relative humidity were evaluated. Type sensor HOBO RH Temp was located 2 m above the ground where was the measuring of instantaneous values carried out in five-second intervals. The results were evaluated for each measurement individually. Converting values to percentages, windbreaks can be compared with each other. The measurements showed the different efficiency of the windbreak for each measurement. To create the relevant evaluation is necessary in order to look at many other factors besides the measured values.

Hodnocení parametrů osvětlení na inseminační stanici kanců
Pecinová, Hana
The thesis aims to evaluate hygienic standard of boars breeding which is the base for good reproductive skills achievement. In relation to the quality of the semen, the lighting parameters play significant role among the microclimate conditions. In this experiment the light intensity was evaluated at weekly intervals from March 2012 to March 2013, in ISK Velké Meziříčí. 88 boar breeds were put into the experiment -- duroc, danish duroc and landrace. Light intensity was evaluated in relation to the parameters of sperm quality, which are: motility (%), semen volume (ml), sperm concentration (thousand.ml-1) and the proportion of sperm with pathological changes (%). The analysis of collected data showed statistically significant light effect on the ejaculate quality (P=0,001). When the light intensity have been growing (65,7 lx), the capacity and portion of pathological changes decreased (to 231,3 ml from 279,7 ml and 8,7 % from 9,6 %), while the concentration increased (426,8 thousand.ml-1 from 346,2 thousand.ml-1) in opposite to lower level of light intensity (52,3 lx). During summer the overall quality decreased, which can be caused by both, the intensity of light but also the thermal stress factor.

Mikroklima porostu řepky a pšenice
Krédl, Zdeněk
The purpose was clarification of vertical stratification of temperature and humidity in winter rape and winter wheat canopy and their comparison with the data from standard station. Air temperature and relative humidity was monitored in wheat and rape canopy in Žabčice during the main growth season in 2010 and 2011 years. Automatic sensors were positioned at three levels (on the ground, at the effective height and at 2 meters above the ground). According to crop developmental stage period was divided to three (four) parts. Air temperature and relative humidity in vertical profile of canopy differed significantly in dependence on year, wheat or rape developmental stage and time of day. The differences in vertical stratification of air temperature and relative humidity were pronounced especially during the light part of the day. In this time the temperature in ground part of canopy was significantly lower and the relative humidity was significantly higher. Air temperature measured in wheat or rape canopy was compared with data from standard meteorological stations, also. The results can be used in precision of prediction methods of some harmful agent's occurrence.
