Airconditioning of the passive house
Voleš, Jakub ; Uher, Pavel (referee) ; Rubina, Aleš (advisor)
The aim of this bachelor´s thesis is the concept of the air-conditioning and cooling system for the residential rooms of the two-storeyed house. The technical solution respects functional, hygienic and operational demands on the internal microclimate. The main functional requirement of the air-conditioning system is compensation of the heat losses and the annual inflow of the necessary minimum of the fresh air. The theoretical part of the thesis is concerned about acoustics and it’s connection with air-conditioning. Firstly, the text introduces what is sound from the physical point of view, characteristics and it’s impact on the physiology of the humans. At the end of the theoretical part are mentioned the sources of sound and it’s spreading through the system. Finally, the methods leading to the reduction in harming acoustics effects are presented. The result of the computational part is the design of the air-conditioning unit, the piping and the other components; also the concept of the direct cooling at the summer period. The project part containes the technical report, the attachements and the project documentation for realization.

Direct cooling systems in food processing plants
Kotásek, Petr ; Vlček, Petr (referee) ; Formánek, Marian (advisor)
Diploma thesis deals with direct cooling systems in food processing plants. The work focuses on the description of the components of the refrigerant cycle, with emphasis on the choice of refrigerant. The result is a design of direct cooling system in the food factory in the variants with refrigerant R404A and R717. The work describes the advantages and disadvantages of various options. The work includes an experimental section which deals with the measure-ment and processing of the actual values of the refrigerant cycle and the comparison of two cold sources.

Design of a Testbench for Reduce Temperature Testing of High-Pressure Pump Systems
Škývara, Tomáš ; Čáp, Jaroslav (referee) ; Ramík, Pavel (advisor)
The subject of diploma thesis is design of a testing cabin for high pressure pump testing under low temperature. The objective is to project a cooling system and a cooled testing cabin. Suggested cooling system must be sized to cool down the estimated power and the cabin is supposed to be located inside the existing testbench. There was peroformed an analytical calculation of thermic evaluation, several parts of calculation were verified using ANSYS program simulation. The second section of the thesis is focused mainly on the design, especially on design of testing cabin. The result of diploma thesis is prepared for utilization in Bosch Diesel s.r.o. Jihlava.

Air condition of lodging house
Horká, Lucie ; Rubinová, Olga (referee) ; Šikula, Ondřej (advisor)
This bachelor's thesis deals with the air condition of the lodging house. Design is specialy focused on guest rooms, common areas and the apartment of manager. The project deals with ventilation units, including heat recovery, chillers and the heat source. Designed facilities in the lodging house have achieved the optimum microclimate in the summer and also in the winter.
