Warm-air heating and ventilating system for low-energy family house
Musil, Zdeněk ; Katolický, Jaroslav (referee) ; Jaroš, Michal (advisor)
The diploma thesis deals with warm-air heating and ventilation system of energyefficient family house. The part of thesis is theoretical introduction to low-energy and passive houses, ventilation and heating. The proposal itself is based on the applicable standards and includes all progressive steps, including the calculation of the thermal performance and sizing individual parts of the system. The drawing project documentation is listed in appendixes.

Development of thermal insulation materials based on natural fibers
Slípková, Andrea ; Kout, Pavel (referee) ; Zach, Jiří (advisor)
The thesis discusses possibilities of use new thermal insulation materials based on natural renewable resources (primary technical hemp) in development of the new thermal insulation materials. The main task (in the work) is to find modifications of the thermal insulation mats based on natural fibres by chemicals substances to improve the moisture properties, thermal properties and fire resistance.

Heating system reconstruction
Tajbrová, Lenka ; Košner, Jan (referee) ; Hejčík, Jiří (advisor)
This thesis deals with reconstruction of the heating system of the house after insulation and window replacement. First, the work deals with the description of the building, where are solved the structural elements and building construction and the original heating system is described. Another part deals with the selection of appropriate thermal insulation of external walls and roofs. The work deals with the detailed calculation of the nominal heat performance including domestic water heating. Subsequently, it is focused on solutions of suitable reconstruction of the heating system, which deals with the heat source, hot water circulation, radiators, temperature gradient, heating system security and temperature regulation of water in the domestic water storage heater. In the annexes are inserted construction drawings and the drawings of heating system. Drawings of heating systems are processed for the original condition. For the condition after insulation drawings are already processed with the proposed renovation of the heating system.

Ventilation of multifunctional building
Císař, Milan ; Horák, Petr (referee) ; Adam, Pavel (advisor)
The first part of the Bachelor's thesis deals fire safety issue in the air conditioning. The second part solves the proposal of forced ventilation in the premises of multifunctional building. Each parts of building are designed for a offices purposes, hairdresser's, fitness club and areas for a living. At first, the object is evaluated according a thermal performance and other processes are related with the design of air conditioning equipments (determination of airflows, proposal of distribution elements, dimension of conduits, design of air handling units and reduction of noise). Documentation for implementation of this air conditioning equipments is elaborated at the last part of this work.

Heat exchanger design
Zdvyhal, Marian ; Hrnčířová, Michaela (referee) ; Baláš, Marek (advisor)
This bachelor thesis solves design of a heat exchanger for hot water boiler with gasification chamber for preheating the combustion air with the heat of the combustion products. Calculation values were experimentally measured. Thesis contains brief description of the shell and tube heat exchanger, stoichiometric combustion calculation, geometrical dimensions design of the heat exchanger, pressure loss and thermal performance calculation. It also includes drawings of the designed exchanger.

Energy and environmental assessment of buildings
Kubínek, Tomáš ; Baroň, Alexandr (referee) ; Hirš, Jiří (advisor)
The aim of this thesis is to give a general idea of energy; what it is, how it is created (rather transformed), how it is distributed and used in many of its forms. In detail it describes how buildings are evaluated in terms of energy consumption, how can we lower this consumption and how it affects the environment. Part A, theory, gives a general idea of the theory surounding transformations, losses and uses of energy. It describes processes of assessment of buildings. Part B, calculation methods, give an idea how current CZ/EU regulations describe optimal calculation methods. These methods include: energetic, enviromental and economic evaluation of buildings or energy-saving measures. Part C, project, describes an exact measuring in Elementary School Svážná-Brno. It describes the means of obtaining information. Includes graphically processed monthly energy consumptions. It also includes list of used sensors (measuring air temperature, humidity and surface temperatures), schemes of sensors placements, schemes of building and technical systems. The main part of this project are graphs of measured data made in EXCEL with descriptions.

Influence of vehicle radiator pressure drop on its aerodynamic drag
Pavlovič, Matúš ; Blaťák, Ondřej (referee) ; Vančura, Jan (advisor)
This diploma thesis focuses on numerical simulation of DrivAer vehicle model with different pressure losses of the radiator. CFD models of the vehicle in Estate body version for individual type of riadiator are created, together with a radiator and a simplified engine compartment. The aim of this work is to compare characteristics of conventional aluminium radiator with characteristics of polymeric prototype radiator and their impact on aerodynamic drag of the vehicle.
