Modern energy and decreasing the energy intensiveness of buildings
Kučera, Miroslav ; Popelka, Josef (referee) ; Havlík, Roman (advisor)
This diploma thesis deals with possible energy-savings in the municipal buildings of Spytihněv. Moreover, it discusses the possible improvements of heating features and making use of renewable resources. This is meant to be achieved by a wrapper which is less demanding on energy consumption than those which have been used until now. Attention is also paid to a more efficient system of energy distribution. Both energetic and financial points of view are taken into consideration. The thesis consists of a few parts. Introduction, the first part, deals with renewable resources issues on a theoretical level. The second part is divided according to each individual analysed premise/building. At this point energy-saving proposal, choice of a heating system, a heating pump, a solar collector as well as energy-saving and financial calculation are included.

Optimalize Application of Cascade Convection of a Heat Pumps
Hrnčíř, Zdeněk ; Šenk, Josef (referee) ; Gregor, Jan (advisor)
The introductory part of this diploma work contains a basic thought for the application of the heat pumps cascade connection and further I describe its function and define the notion of an optimum middle temperature.Then the direct comparison of two heats pumps cascade connection with an one-stage heat pump is shown there in a concrete example. The main part of the work is aimed to the determination of the most suitable variant for the heating and for the preparation of a hot service water in a benchmark family house. The systems of heatings are provided in options of a low-temperature floor heating and hot-water radiators. Both types of the heat pumps supply the warm to every heating system. It results into four possibles alternatives of the building heating.Besides of the alternatives mentioned above, a new variant of optimalised cascade connection was arisen during this work elaboration . The first stage of this connection which supplies the warm to the floor heating is disconnected out of the heating season and the second stage provides only a hot service water warming. The results of this work showed us that just this variant of a cascade connection causes savings in energy in comparison with an one-stage heat pump. In the conclusion of this work there are discussed the reached results and indicated the possibilities of a practical exploitation.

Heating motherly school with heat pump and solar collectors with additional heating to the open air pool
Preclík, Vítězslav ; Krhovský, Bohumil (referee) ; Mastný, Petr (advisor)
In 2007, in June the company Europrojekt entered the project with the requirement of the formulation and implementation of heating motherly school by heat pumps in the village Hluk. The projekt was ordered by the management of this motherly school. This is a total reconstruction of the heating system building motherly school, including the use of residual heat for heating the pool water in an open swimming pool, which is located near this motherly school. The requirement is also given to reduce environmental pollution and achieve energy savings. This diploma thesis solves the detailed description of solutions and calculations for each part. In first, the introductory part of the work is focused on getting the project, a description of the object motherly school and a proposal for the energy measure before the realization. Second section is devoted to the selection and design of the system of heat pumps and solar collectors. Next part of work is the use of the residual heat for heating the pool water in the transitional months, i.e. May, September and the main months June, July, and August, when should be the visit of the swimming pool the biggest. In addition, resolving heat recovery through plate exchangers, the calculation of storage tanks, valves insurance proposal, the expansion tank, circulation pumps, etc. The last part thesis addresses the energy and economic assessment of the whole project.

Modern methods of heating system regulation
Zlámalová, Petra ; Kamenský, Petr (referee) ; Hejčík, Jiří (advisor)
Bachelor final project is consists from two main parts. The first part deals with a theoretical introduction to the regulatory elements of the heating system. The second part presents the model examples of the involvement of a specific type of regulation in block of flats, and it is pointing out the possible advantages and disadvantages of this solution.

Small boilers as a source for family houses
Studnicki, Jakub ; Katolický, Jaroslav (referee) ; Štětina, Josef (advisor)
The paper summarizes the basic parameters of boilers with low power for use in family homes. The boilers are divided into chapters according to the used fuel (gas, solid fuels, liquid fuels, biomass, pellets...). For each boiler there are basic characteristics, dimensions, methods of attachment to the wall or floor and if hot water heating is integrated. It is also characterized by a boiler heating system, i.e. the flue requirements, size and location of the water supply for heating. In another part there is an assessment of economic and environmental aspects of boilers. From an economic perspective I focus on a fuel economy and from an ecological mainly on the ratio of fuel efficiency and pollutants emitted into the air.

Hot water heating systems with solar component
Umýsa, Radovan ; Štětina, Josef (referee) ; Katolický, Jaroslav (advisor)
Bachelor's thesis deals with the description of hot-water heating systems using solar elements. This work consists of two parts. In the first part of thesis describes types of hot-water heating systems and their distribution according to different aspects. The following are the basic types of components, which are used in such systems. The work also discusses the use of sunlight to obtain thermal energy using solar collectors. The second part of work is focused on technical-economic comparison of solar heating systems for TV and heating, using two different types of solar collectors.
