PCM-based heat and cold storage
Němec, Lukáš ; Ostrý, Milan (referee) ; Šikula, Ondřej (advisor)
In the first part of the bachelor thesis I will deal with the accumulation of heat and cold using materials with phase change and also the design of a PCM storage tank. The aim of my effort is to design the most ideal spacing of tubes in a given tank, so as to achieve the greatest possible heat capacity. I performed simulation experiments in CalA 4.0. The second part is computational, where I focus on the design of heating in the pension. I solve heating with an air-to-water heat pump. I designed solar collectors for hot water heating. The last and third part is the project, which contains the project documentation together with the technical report.

Construction details of buildings evaluation from energy demand point of view
Císař, Milan ; Šikula, Ondřej (referee) ; Adam, Pavel (advisor)
Theoretical part of Diploma thesis deals with issues about thermal bridges and thermal connections in building structures. The Calculating part focused on the family houses with a low heat use. The results of this part are energy and financial evaluations of family house. The last part deals with the using of computer technology in engineering practice. These chapters devote about computer modeling an assembly details of passive house and family house after reconstruction (the dates of family house after reconstruction are compared with the results from experimental measurements). The last section of this Diploma thesis solves dynamic modelling of particular passive house in simulation program called Trnsys.

Air condition of the restaurant
Král, Tomáš ; Gebauer, Günter (referee) ; Šikula, Ondřej (advisor)
This thesis describes the creation of ventilation systems in the specified restaurant. The pur-pose of this investigation is to design the air conditioning system so as to create the optimal microclimate conditions in all operating parts of the building; such as a kitchen, restaurant, social hall or an apartment. I will use available computer software and adhere to the applica-ble regulations and standards. Using computer simulations, I will assess the current status of the air distribution in respective parts of the building and propose its optimization, which in turn will provide an optimal internal microclimate.

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.
