Community centre ventilation
Pokutová, Karolína ; Rubinová, Olga (referee) ; Uher, Pavel (advisor)
The bachelor thesis focuses on the design of HVAC (Heating, Ventilation, Air Conditioning) systems for a community center. The goal was to create a suitable indoor microclimate for the building by using ventilation unit. The work is divided into three parts. Part one is theoretical section. This part deal with the components of ventilation and air conditioning systems, terminal units and noise in HVAC systems. The second part is calculation section and focuses on thermal balances calculations, airflow calculations, distribution elements, duct sizing, design of ventilation units, noise attenuation calculations and insulation design. The third part comprises the detailed project documention.

Sleep quality depending on room environment
Veličková, Kateřina ; Pokorný, Jan (referee) ; Fišer, Jan (advisor)
The aim of this diploma thesis was to determine the thermal resistance of selected sleep assemblies (clothing, mattress, blanket, pillow) using measurements with a thermal manikin and subsequently to determine the appropriate ambient temperatures at which a balanced thermal equilibrium between the sleeping person and their environment would be maintained. Four different assemblies were selected for measurement purposes, differing in the type of blanket used (summer blanket, quilt, cover, and no blanket). The influence of the thermal manikin's position on the measured value was also investigated. It was proven that the influence of position on the overall thermal resistance is negligible, with measured values ranging from 1.12 clo (assembly without a blanket in the side position) to 2.05 clo (assembly with a summer blanket in the back position). Subsequently, appropriate ambient temperatures were determined using the PMV model, which ranged from 24.4 °C to 28.6 °C. The two-node model proved to be insufficiently sensitive for the addressed issue, and the heat flux maps derived from the equivalent temperature model were not calibrated for sleep but for mild activity while seated. Nevertheless, they provided interesting information about the perception of thermal comfort in different parts of the body.

Air-conditioning of Department store
Chorý, Vojtěch ; Rubina,, Aleš (referee) ; Rubinová, Olga (advisor)
The topic of this bachelor thesis is design of air-condition equipment for veterinary clinic. The clinic is located on the first floor of a multifunctional building in Brno city. For design purposes is used warm-air heating, air-conditioning and forced air-replacement. The theoretical part is focused on clean room issue. The Project part contains a project documentation for realization of two air-conditioning equipment. The first air-conditioning equipment is designed for warm-air heating and air-conditionig of clean rooms. The second air-conditioning equipment provides forcer air-replacement of the clinic.

Comparison of Energy Circles from point of view Efficiency
Houdek, Milan ; Škvařil, Jan (referee) ; Lisý, Martin (advisor)
This diploma thesis investigates the combined production of power and heat from biomass. The main aim is to compare suggested energy circles in the light of their electric, general and economic efficiency. Introduction describes the basic terms and principles of energy utilization of biomass, combustion and gasification technology are described thoroughly. The main part contains suggestions and thermal calculations of energy circles. The thermal cycle with gasification chamber, combustion chamber and hot air turbine is proposed, than thermal cycle with gasification generator and cogeneration unit and finally Rankine-Clausius circle. In conclusion calculated results are recapitulated and the usability of proposed thermal cycles is assessed.

Optimization of the indoor climate of an eatery by air conditioning
Mrázková, Hana ; Kašpar, Antonín (referee) ; Šikula, Ondřej (advisor)
This thesis is focused on the optimization of the catering service internal environment by air conditioning in Brno. This concept uses a forced ventilation system and air conditioning. The theoretical part addresses the proper air distribution in the catering operation. The experimental part involves the measurement of carbon dioxide, air velocity, relative humidity and air temperature and the temperature of the thermometer ball. Depending on the observed values a technical solution was created in variations and applied in the calculation program.
