Design karavanu. / Design of a caravan.

Zahradníček, Jan January 2008 (has links)
This thesis aims to design a modern innovative caravan. The main innovation of the proposal is seen in the new interior of motorhome class B for 4 persons with regard to minimal functional proportions. Independenc of energy. The main idea of the whole work is new compact interior designed according to ergonomy of person and with regard to main individual needs of user during their travelling and exterior, which brings a new face into motorhomes.Imterior brings several compromise solutions and several ideas for small spaces like multifunctional furniture. Small compact design for big travelling.

Využívání biomasy k energetickým účelům / Utilization of biomass for energy purposes

Malínský, Tomáš January 2010 (has links)
The Master’s thesis deals with the renewable source of energy, namely with the biomass, and its utilisation in the Czech Republic. The thesis is divided in to two parts. The first part of thesis is theoretical. It summarises in form of literature search the general problems concerning the biomass, closely burning biomass. The second part focuses on practical utilisation of biomass and it´s burning in small scale boilers, designated for heating buildings. Boilers are detailed described. Attention is focused on machinery with automatic fuel supply. Four possibilities of improving them are described in last part of thesis. Automatic ignition, air supply, preheating of air and continuous regulation of process.

Vliv stočení oběžného kola na charakteristiku čerpadla / The influence of the impeller diameter decreasing on the pumps characteristic

Jelen, Richard January 2014 (has links)
This master’s thesis deals with changing the geometry of the output section of the impeller of the radial centrifugal pumps and its influence on the characteristics of the pump. In engineering practice for these radial centrifugal pumps it is possible to change the parameters based on the requirements. This adaptation of parameters is called impeller trimming. Impeller trimming means the reduction of the impeller diameter thereby decreasing the flow, head and efficiency. Existing equations for calculating the changes in the characteristics of the impeller trimming are inaccurate. In this thesis is describes a possible method of putting for the recalculation characteristics of a pump based on the impeller diameter on the available characteristics of pumps.
