Trombe wall and its exploitation in environmental engineering
Med, Lukáš ; Chovancová, Michaela (referee) ; Jaroš, Michal (advisor)
This Bachelor's thesis contains description and measurements of specific Trombe's wall on a family house. Theoretical part consists of different modifications of Trombe's wall and a closer look at different types of temperature measurements. In practical part of this work can be found a description of measured Trombe's wall, a procession of measured data and a calculation of whole energetic and financial contribution of measured period. The results of this work are arranged in graphs and tables.

Mean Radiant Temperature Measurement
Truksa, Lukáš ; Zuth, Daniel (referee) ; Janečka, Jan (advisor)
This work is focused on parametry environment. In particular, this work is focused on the mean radiant temperature, which is a parameter with good meaningful capabilities. In The work we introduce with some ways mean radiant temperature measured and what are currently the sensor for this measurement. An integral part of this work is also Introduce the human thermal comfort, which plays an important role in measurement mean radiant temperature. In another part of the thesis is done propose a simple sensor for measuring the mean radiant temperature. And with other devices that are designed to measure the mean radiant temperature is verifying its functionality.

Assessment of thermal comfort in buildings
Procházka, Aleš ; Pokorný, Jan (referee) ; Charvát, Pavel (advisor)
This bachelor thesis summarises knowleges about methods used for assessments of thermal comfort in buldings. In opening part of thesis is thermal comfort introduces as important part of overall satisfaction with indoor environment. There are also described fyziological basics and ways of thermoregulation and individual elements of thermal balance. Next part of thesis is focused on thermal and humidity factors of indoor environment. Some combinations of these factors form thermal comfort. Main part of thesis describes methods of assesments of thermal comfort using PMV and PPD indices. For practical uses there are examples of comfort diagrams, which are based on PMV index, Thermal Comfort Meter and Thermal Manikin. Last part contains description of some instruments for measurement of used physical values.

Testing method of car air-conditions
Bezděk, Lukáš ; Katolický, Jaroslav (referee) ; Štětina, Josef (advisor)
A topic of bachelor’s thesis is a testing of car air-conditions. The introduction shortly covers the history of the air-condition in the personal vehicle. Following chapters describe a definition of air-conditioning equipment, explaining the cooling principle, and transporting the air to the interior of the vehicle. Air-conditioning device is a complicated unit, thus there are mentioned the main circuits and components, from which the vehicle air-condition is built. The basic division is also included. There is also a big chapter that paid attention to different diagnostic methods of testing the vehicle air-conditions. This chapter follows a proposal of testing device and functional scheme of air-condition measurement. The conclusion summarizes the usage of the cooling media, its impact on environment, and new trends in area of refrigerant.

Radiating shield for sensor outdoor temperature
Janáček, Adam ; Charvát, Pavel (referee) ; Štětina, Josef (advisor)
Bachelor’s thesis mentions methods for outside temperature measurement; each of this method is briefly described. Principles of outside temperature measurement, regarding placing of the temperature sensor, are shown. Importance of use of radiation shield for more precise measurement is pointed out. Radiation shield’s function and construction of aspirated and self-aspirated shield, as well as their main advantages and disadvantages are described. Market research then shows radiation shields made by their main manufacturers, each shield is briefly described. Two radiation shields, aspirated and self-aspirated, are designed, with respect to simple construction and knowledge gained during market research

Surface temperature measurements by IR camera
FUKA, Miloš
The master's thesis is devoted to the history and performance of non-contact temperature measurement, characterization of infrared cameras and infrared thermometers. Temperature is one of the most important physical quantities. Using an infrared camera we obtain information about the surface temperature in all picture. In the master's thesis is included the measurement and capturing the fatal defects on the punched billet, finding out the quality of temperature field and the quality of the overlapping work rolls. During the measurements were used infrared cameras TIM200, TIM400 from the company Micro-Epsilon and infrared cameras SC325, SC660 from the company Flir.

Sledování změn krajinného prostředí prostřednictvím analýz multispektrálních satelitních dat v okolí jaderné elektrárny Temelín
Jihočeská univerzita v Českých Budějovicích, Zemědělská fakulta, České Budějovice ; Vácha, Aleš ; Havelka, Ladislav ; Pechar, Libor ; Brom, Jakub ; Procházka, Jan ; Hais, Martin ; Pecharová, Emilie
Cílem studie je: 1. Terénní monitoring teplotně-vlhkostních parametrů krajinného krytu na lokalitách zemědělských kultur a lesních porostů sledovaných v předchozích letech; 2. Pořízení a zpracování dvou družicových scén družice Landsat TM 5 z hlediska teplotně-vlhkostních parametrů krajinného krytu; 3. Syntéza dlouhodobého sledování teplotně-vlhkostních parametrů krajinného krytu; 4. Hodnocení sledovaných ploch za využití termovizních metod: Pozemní průzkum bude doplněn o sledování pomocí termokamery ThermaCam 695, která poskytuje údaje o radiační teplotě povrchu (poslouží jako podklad pro hodnocení pomocí dálkového průzkumu Země). Všechny údaje doplní dlouhodobé řady monitoringu.

Meteorological quantities measurement
BEZDĚKA, Vladimír
The thesis consists of 95 pages and 41 pages of enclosure. Pictures, charts and colour graphs are included. The thesis and the enclosure contain data presented in charts and from the charts graphs have been made. Also, internal material provided by the Czech Hydrometeorological Institute, České Budějovice 7, Antala Staška 1177/32 is incorporated, as well as data from two amateur weather-stations situated in České Budějovice and Hluboká nad Vltavou. The objective of this work is to explain and describe measuring apparatus and methods used in meteorology. The work also compares results gained from a professional weather-station with those from an amateur one.
