IR teploměr s automatickou korekcí emisivity / IR thermometer with automatic emissivity correctionDobesch, Aleš January 2013 (has links)
Diploma thesis deals with basic physical quantities and laws relating to non-contact temperature measurement and emissivity determination of solids. It describes the design and implementation of the IR (Infra-Red) thermometer often missed with automatic emissivity correction. The first chapter explains the concept of temperature and basic principles of temperature measuring . The second chapter focuses on the history and theory of non-contact temperature measurement. Gradually are explained the concepts related to non-contact temperature measurement and the problem of determining the emissivity of the body. Next third chapter describes the proposed hardware solution of IR thermometer. The fourth chapter describes a software written for the IR thermometer. The fifth and last chapter summarizes the findings and knowledge from the implementation of non-contact thermometer and measuring emissivity.

Ekonomické systémy chlazení budov / Economy building refrigeration systemsKohút, Radovan January 2012 (has links)
The thesis deals with the refrigeration systems. It analyzes ways to optimize the refrigeration process and the associated energy savings. In a practical application on an industrial building where there is the need of cooling the machinery, it compares the reference system with another two optimized alternatives. The heat recovery alternative supports heating and hot water supply and the water-side free cooling alternative lowers the energy consumption during the cold period of the year. The experimental section assesses the suitability of floor cooling in relation to the stratification of air temperature along the height of the room and the effect on thermal comfort of people.

Snižování pracovních teplot při výrobě a pokládce asfaltových směsí / Reducing the operating temperature of the production and laying of asphalt mixturesKomenda, Radek January 2013 (has links)
The subject of this thesis is the issue of reduction of the operating temperatures in the production and laying asphalt mixtures with a more specific focus on influencing the functional properties of these mixtures, especially low-temperature parameters. The thesis is notionally divided into two parts. The first part refers to the low-temperature asphalt mixtures and the second part pays the attention to asphalt mixtures with an added R-material. For production of asphalt mixtures in the first part of thesis were used five additives and for the second part were used a total of four different asphalt mixtures which differs in the participation of added R-material. Both parts are divided into a theoretical part, which discusses the existing experience, the use of these mixtures and the practical part, which analyses in detail the tested mixture ( the composition and preparation of tested specimens ) and deals with the result of laboratory test. In particular, it is a test of asphalt mixture resistance against the formation of frost cracks according to ČSN EN 12697-46 and by comparing the individual mixtures in comparison with the reference sample and among each other.

Zdravotně technické instalace v obytné budově / Sanitation installation in a block of flatsMajtán, Peter January 2014 (has links)
The diploma thesis deals with the problematics of both health and technical installations in a residential building in the city of Brno. The theoretical part deals with the analysis of the topic with particular focus on the problematics of thermal losses within the pipeline. The thesis also focuses on various possibilities of protection of the pipeline and reduction of the thermal losses. The project part of the thesis deals with both health and technical installations in the particular building within the chosen option. The concerned building is constructed in the form of cascades consisting of five floors above the ground level and one underground floor which serves as a parking lot for the cars of the building residents.

Stanovení zkrácených cyklických deformačních křivek superslitiny Inconel 738LC při zvýšených teplotách / Determination of Shortcut Cyclic Stress-strain Curves of Superalloy Inconel 738LC at Elevated TemperaturesŠmíd, Miroslav January 2008 (has links)
Multiple step tests under cyclic strain control have been performed using cylindrical specimens of cast polycrystalline Inconel 738LC superalloy at 23, 700, 500, 800 and 900 °C in laboratory atmosphere to obtain cyclic stress-strain curves. During cyclic straining of specimen were obtained cyclic hardening-softening curves. Their progress changed with temperature and strain amplitude. Evaluated cyclic stress-strain curves are shifted to lower stresses with increasing temperature. Surface relief was observed in fatigued specimens under SEM and metalography under optic microscopy. Slip markings were studied on specimen surface fatigued at 700 °C .Stress-strain response is compared and discussed in relation to the surface observations - persistent slip markings.

Meteostanice s rozhraním Ethernet / Weather Station with Ethernet InterfaceNovák, Pavel January 2013 (has links)
This thesis deals with the design and construction of the meteorological station. The meteorological station is designed and constructed to be able to measure the basic meteorological parameters (temperature, humidity, air pressure) and the other three variables (measuring rainfall, wind speed, wind direction). This thesis will introduce you to meteorology. Meteorology determines the daily weather forecast and the results are used for examples in aviation or maritime affairs. The method of atmospheric origin is given in the theoretical part. Meteorology must use measuring instruments to determine quantities. The dissertation also includes analysis of the measuring instruments. The meteorological station uses the Ethernet technology. In the chapter devoted to Ethernet are described its principles, types and method of power supply over Ethernet. The following section describes the design of the entire meteorological station, selection of all components and description of their connection. The chapter about implementation contains a description of the parts which forms program part of the meteorological station. The aim of the thesis is a summary of the achieved results including price comparison of the renovated meteorological station with other meteorological stations, which can be normally bought.
