Manufacturing of mudguard holder using forging technology
Ondráček, Miroslav ; Podaný, Kamil (referee) ; Šlais, Miroslav (advisor)
The diploma thesis deals with problems of drop forging. A detailed literary study is prepared in this work, in which there are data for working out the specified component – mudguard holder. There are options for cutting the semi-product, types of lubricants, construction of ideal preform or different kinds of forging machines for drop forging. The next part of this thesis is about technology of drop forging on crank forging presses. This section is aimed on technical drawing of the forging and its classification by the complexity of the shape. Furthermore, the thesis deals with the economic part, setting out the individual costs of the production from which the cost price of a forging is determined.

Air-water heat pump
Ondráček, Miroslav ; Moskalík, Jiří (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with modern detached house heating by heat pumps. Heat pump is an energetic device able to withdraw (at relatively low temperature) thermal energy from surrounding environment and transform it to heat usable for heating a house or warming up water or a swimming pool. For the process to work, it is necessary to provide a little electrical energy to propel a compressor. Relation between thermal energy gained and electrical energy supplied is then called a heating factor. The heating factor is usually between 3 and 5 according to heat pump operating conditions. The lower is an output temperature, the higher is the heating factor. An underfloor heating operated at 35 degrees Celsius (while the house is warm enough) is ideal for using the heat pump. The thesis describes various heat pump types and their advantages and disadvantages. Air/water heat pump is then explained in more detail including estimation of investment rate of return compared to gas heating.
