Ventilation in sports facility
Frühauf, Patrik ; Šikula, Ondřej (referee) ; Rubinová, Olga (advisor)
The bachelor thesis deals with ventilation in sports facility. The objective of this work is to design two or three air-conditioning units in the part of assigned building. The bachelor thesis is divided into three main parts: theoretical part, calculation part and project.The theme for theoretical part is air distribution. Attention is especially devoted to airflow in a room, piping system and distribution elements. The calculation part is practically focused on designing of air-condition units. The last part of bachelor thesis is formed as documentation for sports facility.
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.
Industrial hall cooling
Sliva, Matěj ; Gebauer, Günter (referee) ; Šikula, Ondřej (advisor)
This bachelor thesis deals with the issue of working conditions in heat in the workplace of the powder coating plant production line, especially summer operation. The largest heat source here is from the surface. The aim is to optimize measures to reduce heat stress for workers. This is solved by CFD simulations in Designbuilder. It is expected that this will be the first way in which it will evolve in the future. Each simulation focuses on alternative cooling methods or combinations thereof. The work environment requirements for each simulation are evaluated by the WBGT indicator for hot operations.
Air-conditioning for kindergarten
Horina, Petr ; Šikula, Ondřej (referee) ; Rubinová, Olga (advisor)
This bachelor thesis deals with the project of ventilation system for the nursery school. The ventilation system provides that the fresh altered air is routed in and the used air out. By this compulsory ventilation, a required microclimate is reached, both in the classes and the kitchen which is also placed in the nursery school building.
Optimization of cooling of a family house by using a geothermal system
Buchta, Jan ; Formánek, Marian (referee) ; Šikula, Ondřej (advisor)
The master’s thesis deals with optimization of cooling system of family house using borehole heat exchanger as a single cooling source. In the experimental part of the thesis was carried out long-term mearurements. The main part of the master’s thesis is the development and verification mathematical and physical model of thermal behavior chilled room. The result are computer simulations and evaluation of individual scenarios and design requirements for a potential optimization of measurement and control system. The theoretical part generally deals with radiant cooling systems.
Energy and water management in a residential building
Auer, Zbyněk ; Vendlová, Lucie (referee) ; Šikula, Ondřej (advisor)
The bachelor thesis deals with the management of energy and water in a residential building. For the energy balance of the residential building were used computational tools NKN II and outputs simulation on software BSim2000. On the basis of the calculations were prepared Et-curve for the residential building, which was subsequently supplemented by real measurement.
Radiant heating of industrial halls
Rybář, Jakub ; Vilímek, Pavel (referee) ; Šikula, Ondřej (advisor)
Indoor climate of industrial halls is now advantageously shaped radiant heating systems, which are more flexible and efficient than convection systems. The crucial component of indoor climate in these systems mean radiant temperature. The work focuses on theoretical and experimental research on the location and operation of radiant panels. For the theoretical part is used new computer software able to calculate the Institute TZB mean radiation temperature distribution in 2D space. The experimental part was carried out comprehensive measurements of indoor climate parameters specific industrial halls and subsequently compared. Work includes the design and comparison of three variants of heating in the indoor facility.
Thermal behavior and energy demands of low-energy office buildings
Pichová, Lenka ; Adam, Pavel (referee) ; Šikula, Ondřej (advisor)
The thesis deals with energy intensity of a low energy office building. In the thesis, em-phasis is put especially on the calculation of energy consumption for heating (cooling). The energy intensity of the building is determined and evaluated by four methods of calculation, which are compared with a valid certificate of energy performance of the building, which arose at the time of its construction. In the experimental part of the the-sis, the energy intensity of the building is compared to the actual energy consumption obtained by two experimental measurements in heating season 2012/2013. (The building is operating partly only). Different methods of solutions and valid legal regulations are elaborated in detail in the first part of the thesis.
High temperature energy reservoir with year-round operation in conjunction with a solar system
Hoc, Pavel ; Šikula, Ondřej (referee) ; Hirš, Jiří (advisor)
In this thesis I deal with the issue of stand-alone solar system development. This system ensures the supply of all the energy needed for a reference house. It consists of a solar concentrator and a heat reservoir. I used mathematical models to solve this issue. The calculations showed, that the concentration of solar radiation into the heat reservoir can usually achieve 69 % efficiency. The efficiency can be even higher when using a very reflective materials of the solar concentrator. In this thesis, the thermal reservoir is described and its improvements are suggested based on the optimization calculations. Thanks to knowledge gained during solving this issue, a prototype of the stand-alone solar system is going to be built. All findings will be experimentally verified with this prototype.
Ventilation of a primary school
Urban, Erik ; Bahr,, Josef (referee) ; Šikula, Ondřej (advisor)
The bachelor thesis addresses the first part to the microclimate in school buildings. The second part concerns the proposals of forced equal pressure ventilation of single-storey primary school. In the third part, the technical documentation of the proposed ventilation equipment is processed.
