Air-conditioning of lecture rooms and offices
Bečvář, Jaroslav ; Patočka, Stanislav (referee) ; Janotková, Eva (advisor)
The diploma thesis is consisting of two parts. Forepart is a theoretic survey. It construes basic office of the air conditioning and deal with used air conditioner arrangements. More deeply it deals with air conditioner systems with refrigerant and the air conditioning for electronic equipments. Project of split system for air conditioning lecture rooms and schoolrooms, and units for air conditioning rooms with cluster and server is processed in the second part. Project is derives from calculation thermal stress of air conditioned space. There is calculated price of air conditioner system and made comparison offers of several accessible suppliers. Elaboration drawing documentation of project is part of the diploma thesis.

Optimization of Cabin Environment in Small Transport Aircraft
Fišer, Jan ; Janotková, Eva (referee) ; Masaryk, Michal (referee) ; Patočka, Stanislav (referee) ; Jícha, Miroslav (advisor)
The thesis deals with design and optimization of environment in cabins of small transport aircrafts, especially in terms of thermal comfort and quality of ventilation. The design of air distribution systems and structural design were optimized and most important parts of cabin design with highest impact on the quality of thermal comfort and ventilation were identified based on literature research and experience of the author. The chosen modifications and their influence on the microclimate inside the cabin were investigated using the CFD model, which was validated by results obtained from measurements of flow and temperature fields in the cabin mock-up of small transport aircraft EV-55. Next optimizations were investigated: The type of air distribution system, The geometry of ducts of air distribution system, Thickness of thermal insulation and Emissivity of internal surfaces. Thermal comfort was assessed based on the methodology of the equivalent temperature and comfort zones diagram developed by H. O. Nilsson and for assessing the quality of ventilation the concept of based on index of the age of the air was used. Fifty cases were simulated in total and base of its results Modified mixing ventilation with original air ducts geometry have been evaluated as an optimum. The ducts geometry of Modified mixing ventilation system was suggested by author specially for the thesis. In combination with high thermal insulation of walls and high emissivity of the interior, then this system of ventilation ensures maximum thermal comfort and quality of ventilation for the investigated range of environmental and operational conditions.
