Airconditioning of the house to the medical service
Vytasil, Michal ; Jelínek, Ondřej (referee) ; Rubina, Aleš (advisor)
This bachelor's thesis deals with the design of air conditioning equipment in the house to the medical service. The solution is the basement floor with a waiting room, reception and sanitary rooms and 1.NP with surgery. Heating load of part of the basement is completely drained air handling units, in other rooms are used sub-system with fan coil units. Sanitary rooms are exhaust ventilation ceiling-suspended equipment. In the theoretical part of the thesis focuses on the bypass factor, surface temperature of the heat sink and their effect on the dehumidification.

Ventilation of a multifunctional house
Husák, Martin ; Rubina, Aleš (referee) ; Rubinová, Olga (advisor)
The bachelor's thesis deals with the design of ventilation equipment and air conditioning for a multifunctional building, which has 4 doctor's offices, a hairdresser, a driving school and 3 residential flats. The house is designed to meet all the necessary requirements regarding ventilation. Air handling units are designed to discharge degraded air to the exterior and bring fresh air back. Thermal comfort for the winter is ensured by radiators and in the summer by air conditioning. The theoretical part is focused on climatic conditions for the design of air conditioners, refrigeration systems and refrigerants.

Evaluation of noise of ventilation outlet for a passenger car cabine
Libřický, Stanislav ; Vaňková, Marie (referee) ; Jedelský, Jan (advisor)
The thesis deals with issues of noise ventilation outlets in a passenger car. There is a description of the noise reduction in the acoustic background, optimizing experimental measurement methodology and familiarization with measuring equipment. The next step includes measuring of individual outlet options, results post-processing and comparison of tested alternatives. Based on these results the best variants are chosen and measures for decreasing noise in the ventilation outlets are proposed.

Dynamic Characteristics of Exhaust System and Noise Transmition to the Car Cocpit
Novotný, Václav ; Ramík, Pavel (referee) ; Svída, David (advisor)
This thesis deals with the complex analysis of dynamic characteristics of the exhaust system and the transmission of noise from exhaust system to the vehicle. In the first part is performed modal analysis, which is compared to experimentally measured data. Modal analysis of the complete exhaust system is made with focusing on the influence of temperature of the exhaust system. There is also performed an analysis of noise transmission from exhaust system to the car cockpit.

Proposal to change the categorisation of work at the selected workplace
Plánková, Barbora ; Rozehnalová, Jana (referee) ; Maradová, Karla (advisor)
The diploma thesis deals with work categorization falling into the issue of occupational health protection. The theoretical part is devoted to current legislative reguirements of the EU, the Czech Republic and relevant standards. It also provides a general overview of the system of public health authorities together with a more detailed description of the work categorization topic and related concepts and requirements. This thesis has been made in cooperation with Varroc Lighting Systems, s.r.o., Nový Jičín. The practical part deals with the suggested change of categorization of the optimized assembly line work positions for car rear lighting (B479 OUTER RL). The main aim of this work is to check the correctness of the classification of individual work positions. The intention of updating the categorization is also to reduce the negative impact of critical risk factors of working conditions, which brings benefits for both employees and employers. The specific course of the classification of individual risk factors with a focus on the noise as a critical risk factor is demonstrated on the riskiest work position of the assembly line. In the end, the achieved results of updated classification of all positions are evaluated. The follow-up changes and the resulting benefits of updating the categorization, including other practical recommendations, are also summarized.

Passenger Car Internal Acoustics
Prokšová, Lucie ; Řehák, Kamil (referee) ; Novotný, Pavel (advisor)
The thesis is focused on the analysis of the acoustic properties of the interior of the passenger car by using the finite element method. Part of the work is an analysis of the excitation effects of individual vibration sources and the evaluation of the response in the interior of the cabin with a focus on the passengers of the vehicle and also solving the problem of the design of structural modifications in order to reduce the noise inside the cabin.

Noise control of computers-application of optimal sound isolation layers and fun rotation speed
Kunovský, Martin ; Mišun, Vojtěch (referee) ; Pellant, Karel (advisor)
This thesis deals with the distribution of noise in the computer case and radiation into the neighborhood. Influence of geometrical shape and size of the computer case on radiated noise from the computer was investigated as well as effect of placement of the fan. Reducing noise by using sound absorbing material into computer case and result of the suitable position of the computer in the working environment were also tested. Simulation of the noise diffusion and effectivity of anti-noise equipment was executed in Ansys FEM program.
