Detached house
Bobek, Michal ; Žižka, Lukáš (referee) ; Vajkay, František (advisor)
This bachelor thesis deals with design and creation of project documentation for realization of object of family residence in the Radotín, Prague 16. The parcel 2087/66 determined for object is located on the cadastral territory of Prague 16 and it is suitable for construction of quite formidable family houses and buildings of villa house character. The surrounding development is not older than 5 years. The design respects spatial plan and it does not stand out of character of sourrounding development. The attached project documentation is created in concordance with actual valid laws, notices and norms. The solved object is a building of bigger family residence with two overground floors, without basement and with garage for two cars. It is assumed that the building is to be used by five people. The object contour is irregular and roofs are done by two flat roofs. The construction systém of walls is designed as aircrete block system. Object is composed from one housing unit with all accessories.

Utilization of absorption systems in the heating systems
Vidlák, David ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
Main goal of this work is familiarization with basic features of absorption heat pumps and it’s growing importance on the market. In the first part of the work there is a research for clarifying facts associated with such pumps. In the introduction there are descriptions of basic information from the field of heating industry and its connections to our systems. Next there is a brief analysis of price changes in electricity and heat in the last five years. Main part of the analytical section is a description of the used absorption system. Second part of the work is focused on the calculation of the absorption system itself. First there is calculated internal and external part of the device according to the parameters from GE Power s.r.o. After this step there are parametric studies based on changes of key parameters of the default device for a demonstration of the behavior of a heating pump. In the end of the work there is a integration of the unit into the heating cycle for variations including flue gas condenser and using a cooling water from the turbine condenser.

Development and Implementation of Energy Savings and Energy Management Methodology in an Industrial Enterprise
Dudarev, Ivan ; Demeč, Peter (referee) ; Suchánek, Rostislav (referee) ; Blecha, Petr (advisor)
V současné době se problematika energetických úspor dostává do popředí zájmu jak na úrovni jednotlivých podniků, tak i na úrovni celého státu. Často bývá příčinou sporů ve vědeckých kruzích i mezi odborníky z praxe. Lidstvo tradičně začalo využívat energii z minerálních přírodních zdrojů, které však ve srovnání s obnovitelnými zdroji energie mají omezení. Výzkum a implementace moderních technologií jsou ztíženy otázkou investic a časově omezeny. Proto se evropská strategie energetické bezpečnosti zaměřuje na energetickou účinnost, která je jedním z nejefektivnějších způsobů zlepšení bezpečnosti spotřeby energie. Velké společnosti a podniky jsou jedním z hlavních spotřebitelů energie. Proto je tato vědecká práce zaměřena na problematiku úspor energie a zlepšování energetické účinnosti podniku. Těžiště práce spočívá ve vytvoření a zavedení metodiky pro úsporu energie a managementu hospodaření s energií ve výrobním procesu automobilového podniku. Dále je pro účely této práce vytvořen a popsán způsob vizualizace spotřeby energie v prostředí virtuální reality

Improving energy efficiency in industry
Kovář, Štěpán ; Konečná, Eva (referee) ; Touš, Michal (advisor)
This Bachelor Thesis deals with the increase in energy efficiency in industry. The energy consumption is globally one of the cardinal topics. A significant part of the energy is consumed by industry, and therefore it is necessary to search for such measures to increase the energy efficiency of industrial processes. Current attitude aims at the installation of more effective machines, devices or the waste heat recovery. Especially the scientific community is concerned with the possibilities of process optimization from the point of settings and process integration, production planning, using software solutions. Both approaches are analysed in this work and based on that current state as well as the potential of the energy savings are evaluated.

Improving energy efficiency in industry
Kovář, Štěpán ; Vondra, Marek (referee) ; Touš, Michal (advisor)
This Bachelor Thesis deals with the increase in energy efficiency in industry. The energy consumption is globally one of the cardinal topics. A significant part of the energy is consumed by industry, and therefore it is necessary to search for such measures to increase the energy efficiency of industrial processes. Current attitude aims at the installation of more effective machines, devices or the waste heat recovery. This approach can lead to massive investment requirements of energy audits which means that the motivation of the enterprises to implement such audits is lowered. Especially the scientific community is concerned with the possibilities of process optimization from the point of settings and process integration, production planning, using software solutions. Both approaches are analysed from the potential of their use in this thesis.

Energy efficient hydraulic system design for force loading of vehicle drivetrain systems
Robenek, Vít ; Ožana, Otakar (referee) ; Houška, Pavel (advisor)
The thesis focuses on a hydraulic system design for a specific application of hydrostatic drive with regard to energy efficiency of proposed solution. Standard hydraulic and electronic components are used, mostly products of Bosch Rexroth. The aim of the thesis is to carry out a complex design from mechanic through hydraulic up to the electronic part of the system. After a short introduction in the beginning of the thesis is the particular application described and analyzed. Then the elemental principles of hydraulic devices and systems are explained. In the following part the actual solution is presented, which expands to several different alternatives. These alternatives are compared according to set criteria and the selected alternative is then further developed. At the end of the thesis, the outputs are evaluated and the direction of further possible improvements in the design is outlined.

Energy consumption analysis of water utilities
Bábíček, Michal ; Raclavský,, Jaroslav (referee) ; Ručka, Jan (advisor)
In the first part was an analysis of possible cost-saving measures to reduce energy consumption in the countries of Central and Eastern Europe and the former Soviet Union. Part of the work analyzing energy savings for water treatment plant Bzenecis divided into three parts. Part one deals with a brief description of the individual technological units. In the second part of the individual technological units analyzed in terms of savings already realized by the operator and also in terms of savings that operators shall submit for consideration and possible implementation. The lastthird part summarizes the findings in the second part of the analysis and alsooutlines possible new solutions that are applicable to all objects of the operator.

Energy efficiency of heat pumps
Bártů, Marek ; Hejčík, Jiří (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with the energy efficiency of heat pumps, especially efficiency of air/water system. In the this thesis is simply described the principle of the heat pump and function of each component. It shows the issues of determining the parameters of performance of the heat pump and also describes verification in according to applicable standards. The diploma thesis gives an analysis of determining the energetical efficiency and calculation of coefficient of performance, in other words, the seasonal heating coefficient of performance. Seasonal energy efficiency of selected samples of heat pumps for the heating season is designated for specific climatic conditions.
