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.
Warm air heating and cooling the house
Rodková, Daniela ; Kašpar, Antonín (referee) ; Šikula, Ondřej (advisor)
This bachelor thesis deals with the inner climate optimalization of one - family house to which is associated private swimming - pool hall. In the one - family house there is designed air conditioning for hygienical air exchange, coller system for thermal stress removal during summer period and for heat losses coverage during winter period. In the private swimming - pool hall there is designed air conditioning for dehumidification and warm air heating of the hall. In addiction, there is designed floor heating in selected rooms.The source of heat for floor heating and TV heating - up is solved by new technology, which is, compared to classical boilers, environmentally friendly due to lowering CO2 emissions.
Dynamics of heating surfaces behavior
Oravec, Jakub ; Gebauer, Günter (referee) ; Šikula, Ondřej (advisor)
The diploma thesis is focused on the research of dynamics of selected heating surfaces behavior. The aim of the thesis is to determine the dynamics of heating and cooling and to determine the effect of these characteristics on energy consumption of the building. The project part deals with the design of a heating solution for a residential building in three variants. An Energetic simulation is made for the designed variants, that compares the consumption of thermal energy during one year. The next simulation research the dynamics of selected large-scale heating surfaces. For each construction, nonstationary models of heating up and cooling were made, which are compared in terms of the thermal inertia.
Comparison of heat losses calculation by CSN 06 0210 and CSN EN 12831
Elcner, Jakub ; Šikula, Ondřej (referee) ; Košner, Jan (advisor)
The diploma thesis deals with comparison of heat loss calculation by CSN 06 0210 and CSN EN 12831. This work contains short introduction to the heat loss calculation, definition of basic terms, detailed analysis of heat loss calculation by both standards, description of exemplar buildings, heat loss calculation and heat requirement for heating of buildings according to particular standards. At the end of the work the comparison and discussion of calculation results is presented.
Air conditioning of lecture halls
Vojkůvková, Petra ; Gebauer,, Günter (referee) ; Šikula, Ondřej (advisor)
My thesis deals with evaluation of the current state of microclimatic conditions of problem areas in the L. Jaros Grammar School in Holesov and designing optimal air conditioning. Based on the measurements and simulations of airflow that were carried out, the design includes solution of air regulation and selection of appropriate options to its distribution, which will lead to improvement of thermal-moisture microclimate.
Optimizing of air distribution in schools
Cigánková, Kristýna ; Šíma, Jiří (referee) ; Šikula, Ondřej (advisor)
The thesis deals with the issue of indoor air quality of schools and kindergartens. It focuses particularly on the inadequate ventilation and the application of forced ventila-tion in these types of buildings. The proposed solution is applied to a kindergarten in Kuřim. Measurements of the C02 concentration levels were performed in the presence and absence of air conditioning. To elaborate the proposed solution a simulation was made using a software called ANSYS Fluent. Input values for the simulation were obtained from an experimental measurement of a ventilation diffuser made by a company called Climecon ROX using the PIV method. This diffuser was then installed in the kindergarten. The measure-ments were carried out in the framework of the project the experimental validation of numerical models of the air flow in buildings marked with FAST-S-6-3387.
Heat recovery in Building Services
Hrabová, Kristýna ; Plášek, Josef (referee) ; Šikula, Ondřej (advisor)
This thesis deals with the optimization of sewer heat recovery. For proper design and optimization it is necessary to use three basic methods: diagnostics, heat balance calculations and modeling. In 2D software Area Calculation are simulated different types of sewer exchangers arranged in sewer pipes. Using models of software CalA and simulations will be selected optimal variant. Using software BSim, which is based on more zone numerical simulation of the energy needs of buildings in relation to indoor climate, are detected heat needs of an office building. The optimal number of sewer exchanger is designed from the identified performance heat exchangers and supplies heat for the building.
Ventilation and heating system of a production and storage hall
Bližňák, Jakub ; Šikula, Ondřej (referee) ; Krejčí, Vladimír (advisor)
The objective of this master thesis is to design heating and ventilation systems for a production and storage hall and a contiguous administrative part of the building. The basis of design is in calculation of thermal losses and gains of the building. The objective of design is to reach requisite microclimate for single spaces and operations. System of heating, ventilation and cooling are elaborated in drawing documentation.
Analysis of HVAC systems of a low-energy house
Urban, Erik ; Bahr,, Josef (referee) ; Šikula, Ondřej (advisor)
In the first part, the diploma thesis addresses the issue of comparing individual HVAC systems for family houses. The second part is an experimental measurement of HVAC systems of a low-energy family house. The third part deals with the current state of heating and air conditioning of the family house, together with a certificate of energy performance of buildings. The diploma thesis is more focused on the experimental part.
Mathematical Models for Analytical Calculation of Energypiles
Oravec, Jakub ; Šikula, Ondřej
A current trend is to reduce the energy performance of buildings by using alternative sources for heating and cooling. One of the most promising, and so far unprecedented sources of heating and cooling, is the use of energy from the earth using the thermally-activated foundation piles of a building, the so-called energy piles. The paper deals with an overview and comparison of computer-aided analytical models of energy piles. The individual analytical models are compared (categorized) from the point of view of their physical complexity, computational costs, and thus their usability for the purpose of optimizing energy-pile equipment or assessing the long-term energy efficiency of an energy pile field. Selected mathematical models were algorithmized, and the results obtained were compared with a more robust numerical solution performed using CalA 4 software.
