Honeywell Heat Pump Controller Automated Test
Ruhás, Sándor ; Macho, Tomáš (referee) ; Fiedler, Petr (advisor)
This work deals with the design and realization of an automated test software for the Honeywell superheat controller. The first part of the project includes brief description about embedded systems and heat pumps. Afterwards testing principles are covered in a short chapter, followed by a description of the Honeywell superheat controller. After these chapters actual software structure will be introduced to the reader- with a detailed description of the most interesting parts. At the end of the document there will be a summary what was achieved exactly, and what was the plan. After this summary, the reader can study almost all the Virtual Instruments created during the development of this project.

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.

Power harvesting sensors
Arnošt, Karel ; Klusáček, Stanislav (referee) ; Beneš, Petr (advisor)
The thesis deals with power harvesting sensors as a source of energy. As the power requirements for microelectronics decreases the environmental energy sources become more perspective. In a few last years batteries reach a higher capacity but there is still problem with their replacement. Power harvesting sensors appears as a good solution for powering microelectronics.

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.

The long-term accumulation of solar collectors and the subsequent use of the heat
Litera, Jiří ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
The aim of the thesis is the design and evaluation of the long-term accumulation of solar collectors and the subsequent use of the heat. The basic principles of the use of solar energy are introduced in the theoretical part as well as the list of available heat pumps, solar collectors moreover options for the accumulation of heat are evaluated. In the practical part the system of a long-term heat accumulation for a partially restored family house is designed, where accumulation into water or gravel are the two presented options. Solar energy is collected by solar collectors and accumulated in the long term storage. The system involves water to water or ground to water heat pump that reduces the temperature of the reservoir in order to increase the temperature difference of the system. Both options require a large volume of heat collecting, including large surface of solar collectors. Because of the high cost and spatial requirements the system shows to be hardly realistic in practice. For this reason an alternative solution of a family house heating system more suitable from the economic point of view is described. As a result it was proved that system of the long-term accumulation is not an appropriate solution for heating system of family houses and it is used in places with enough space for the accumulation such as high capacity trays or flooded mines. For existing family houses (partly insulated and with a heat source such as natural gas) the usage of the heat pump eventually supported by solar collectors appears as the most sensible solution. Such solution shows a return of investment from 14 to 25 years, and contributes to sustainable development and to reduction of non-renewable primary energy.

Alternative Energy Resources for Family House
Buráň, Petr ; Štelcl, Otakar (referee) ; Špiláček, Michal (advisor)
In this bachelor thesis we will focus on alternative energy resources for family house. The thesis consists of two main chapters. The first chapter is focused on research, in which we will sequentially introduce different resource of energy and describe their principle of operation. In the second chapter we will create proposal designs for different energy resources for family house and their price comparisons.

Heating of Family House by Heating Pumps
Kordiovský, Jan ; Moskalík, Jiří (referee) ; Lisý, Martin (advisor)
Bachelor’s thesis deals with the topic of heating of family house by heating pumps. Fundamental principle of their function is there explained as well as possibility of performance evaluation, different modes of operation with an additional heat source and basic distribution according to divergent criteria. In the next part were selected three types of heating pumps: air/water, ground/water and water/water. Advantages and disadvantages are evaluated for each of them. There is the question of the appropriateness of application to family houses.
