This diploma thesis addresses the economic assessment of the methods of heating and combinations of technologies for energy saving. The objective of this work is to assess the economical effectiveness of individual types of sources of heating. It is first necessary to established gross requirements of energy for heating, water heating, and other household operations. Based on this information, suitable sources are determined. Alternative energy sources are other aspects for consideration – controlled ventilation with heat recovery, and photovoltaic cells. The aim of the thesis is to identify which combination of those technologies is the most economically effective for the opted house. This work aims to help the investor in decision making about the technological solution of heating and power purchase. The outcome is a complex evaluation of different options for the assessed house.

This work is focused on the design of the peristaltic pump drive for medical purposes. Its initial goal is closer introduction of peristaltic pumps and stepper motors. Then the design of BLDC motor will be made and the use of this motor will be compared with stepper motor. Design of the BLDC motor will be made using RMxprt. Last but not least simulations of both types of motors for the peristaltic pump will be created in Simplorer. Finally, the program LabVIEW will be introduced and a program for controlling a stepper motor will be created.

The diploma thesis deals with design of a suitable heat source for heating and hot water. There are dealt with operational costs of different types of heat sources, which are compared with one another. The next part is the implementation of specific proposal of the heat source - heat pump ground/water with deep wells and measuring system. The last part describes measuring several operating modes of the heat pump.

The point of this diploma thesis is heating design with use of heat pump (HP) for nursery building. The first part introduces problems of HP, familiarization with historical development, working principle, description of components, working cycles, partition of heat pumps due to the source of lowpotential heat and possibilities of working operations. In practical part then follows heat loss computation of own building, suitable heat pump choice, economic balance, investment recovery and evaluation of this solution.

The assignment of my diploma thesis is to design the family house heating system. The source of energy is heat pump for heating which takes heat from areal collector.

The purpose of this diploma work is re-count the hydraulics of the pump and project well-qualified treatment of turbulent pump 65-SVD-2°. Calculations of principál dimensions impeller and side-channel are based upon the theories, experiments and finally on the knowledge gained from the test models constructed. The results of this project can be used for design necessary treatment of turbulent pump 65-SVD and follow-up connection of those pump to the production program of the Sigma pumpy Hranice s.r.o.

This diploma thesis deals with the area of ejectors. In the intoduction, an ejector is classed as an hydraulic machine. There is also an introduction of the principle and application of this machine there. The next part describes two different ways of calculation and there is a suggestion how to get characteristics, that were achieved by calculation in MS Excel, projected. The purpose of this diploma thesis is to confront this mathematical model with the experiment done in school laboratory at Kaplan department of hydraulic machines. The description of this experiment and the evaluation procedure of measured values is described in the final part of this diploma thesis.

The objective of this thesis is the design of an air-water heat pump for heating buildings. The proposed design solution is based on innovative technical concept of a modular system which brings new qualities for the apparatus. One of the major goals of the thesis was to design a versatile system which would replace a wide product range of heat pumps with different heat outputs. The thesis is based on the research part in which an evolution in the field of heat pumps is briefly introduced, followed by the technical and design analysis of present production. The design report contains the description of identified design problems, shows variant design concepts, alternative solutions of parts and details, and finally a detailed description of the definite solution accompanied by a product mock-up in 1:3 scale.

The task of the diploma thesis ‚‚Adjustment of the pumping station and delivery pipeline of the raw water to location of JETE for considered building up of new nuclear sources‘‘ is to figure out a capability of the pumping station Hněvkovice to draw a sufficient capacity of a raw water to the Temelín nuclear power plant. In case of necessity, it designs useful adjustment of a pumping station and deliver pipeline for increasing the raw water delivery rate.

The aim of diploma thesis is design math and numeric system, which simulate these features: model of threeplunger piston pump, system of piping and damping elements. This thesis also contains chapters, which describing numeric models of particular’s elements of system with charts of function dependencies from computation’s program. The last chapter contains numeric model of treeplunger piston pump without damping elements. Continuation of my diploma thesis should be a harmonized of damping elements and designed pump.
