The impact of HVAC systems on the acoustic microclimate of clean rooms
Jelínek, Ondřej ; Mathauserová, Zuzana (referee) ; Papež,, Karel (referee) ; Rubina, Aleš (advisor)
The work description is to create a system of measures to prevent the spread and the consequent attenuation of sound in air handling systems serving the cleanrooms. The thesis presents a solution to noise attenuation in the investigated area, and in HVAC duct, which uses a commercially available material in the form of sound insulation hoses. In the systém solution is part of the work focuses on the optimal design of terminal elements to distribute air in a clean room. Processing methods utilize theoretical and experimental approach. The experiment comprises a unique analysis of the sound insulation properties of selected products under specific conditions. The data obtained are analyzed and incorporated into the framework of this work created program module for determining the attenuation and noise propagation in an enclosed space. Math and physical dependence are programmed into their own DLL by programming language DELPHI.

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.

Intensive care unit air conditioning
Dobrovolná, Natálie ; Uher, Pavel (referee) ; Rubina, Aleš (advisor)
The bachelor's thesis deals with the ventilation system serving hospital premises. The system is divided into two separate functional units. Facility No. 1 serves the ICU (Intensive Care Unit) department and its associated premises. Facility No. 2 serves the facilities of employees, doctors' rooms and associated premises. The design of the equipment meets the relevant standards, hygiene standards and operational requirements. The calculation part deals with the design of air conditioning in the ICU, it deals with the overall analysis of both functional units, heat gains, heat loss, air flows, pressure drops in both functional units and other proposals necessary for the design and proper operation of the air conditioning system. This part is also focused on the distribution and treatment of fresh air. The theoretical part deals with clean rooms, their definition and distribution of air supplied to these rooms. The theoretical part also deals with the installation of operating theaters, images of flow in these areas and their internal microclimate.

Air conditioning of a multifunctional building
Čížek, Vítězslav ; Uher, Pavel (referee) ; Rubina, Aleš (advisor)
This bachelor´s thesis deals with an air conditioning system that serves for warm air heating and ventilation of a multifunctional building. The systém consists of two functional units. The first part will be operated by devices no. 1, 3 a 4, which provide warm air heating and ventilation for the spaces of the playing courts. The second part will be operated by device no. 2, and will serve for warm air ventilation of the facilities for the playing courts. The theoretical part of the thesis focuses on heat recovery systems in air conditioning. In the calculation part, the thesis deals with the design of warm air heating and ventilation, as well as the overal analysis of the both functional units, including the calculation of heat losses, heat gains, air flow rate, and pressure drops. The necessary proposals for the proper functioning of the entire air conditioning system, including the distribution and conditioning of air, are provided.
