Buchta, Jan ; Formánek, Marian (referee) ; Šikula, Ondřej (advisor)
The bachelor thesis deals with air-conditioning and system of chilling for two-floor ad-ministrative and storage part of storage hall. The goal is to design air-conditioning sys-tems and to ensure optimal indoor microclimate. The theoretical part compares three systems of combinated air-conditioning. The result is the choice of optimal combinated systems for administrative zone of solved part of building.solved part of building.
Night Cooling in Condition of Czech Republic
Šíma, Jiří ; Katunský,, Dušan (referee) ; Plášek, Josef (referee) ; Šikula, Ondřej (advisor)
The PhD thesis deals with the theoretical evaluation of the potential use of night cooling techniques in condition of the Czech Republic. Mainly aims to evaluate the potential of night cooling, which uses the physical phenomenon of radiation against the night sky. This technique is widely used mainly in the dry and hot regions where there are the most suitable climatic conditions for this cooling method. The work is based on the current state of knowledge in the area of passive and low-energy cooling systems. These knowledges are applied to the conditions of Czech Republic and by using simulations of the energy, behaviour of the buildings explores the benefits in terms of improving of the internal microclimate and from the perspective of economy operation of conventional cooling equipment. In order to establish the benefits of night cooling on the operation of the building in the dynamically changing conditions, the modular simulation program TRNSYS was used, which is suitable for the analysis of energy systems of buildings and their behaviour. The results of simulation results were converted to thermal comfort parameters of the PMV and the PPD.
The Suction Air-Conditioning Equipment
Wernerová, Pavla ; Gebauer, Günter (referee) ; Šikula, Ondřej (advisor)
The Master´s Thesis is dwelling on air flowing in kitchen space of a family house. The work points at the comparison and the evaluation of the results, which were obtained from an experiment in a real object and a simulation in right software.
Analysis and optimization of thermal behavior of buildings
Nováková, Iva ; Gebauer, Günter (referee) ; Šikula, Ondřej (advisor)
The diploma thesis with research of efficiency of renewable and low-potential energy sources of buildings. It is available on numerical simulations for sharing office and heating and cooling system buildings in DesignBuilder. There are various energy sources and ways of controlling heating and cooling. The results are evaluated in terms of time, after the expected compromises in the building, in terms of energy consumption and its price.
Cooling systems and their management in office settings
Kotásek, Petr ; Šikula, Ondřej (referee) ; Formánek, Marian (advisor)
The bachelor thesis deals with the cooling systems of office spaces. The theoretical part focuses on the principle of operation of commonly used cooling systems and the possibility of cold production. This work describes the advantages and disadvantages of each system. The result of the calculation is design of optimal cooling system for the office building, which secures the removing of the heat load in the summer.
Optimising the use of solar energy in the family house
Letochová, Jana ; Gebauer, Günter (referee) ; Šikula, Ondřej (advisor)
This thesis is focused on solar energy as an alternative sustainable energy source and its use in family homes. The first part focuses on possible connections of solar energy systems and their design using software simulations. The second part consists of a design for the preparation of hot water in the family home. Finally, a comparison of the efficiency of the set collector according to different calculation methods is included.
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.
The solution selected aspects of cooling slaughterhouse
Snopek, Milan ; Formánek, Marian (referee) ; Šikula, Ondřej (advisor)
The topic of my diploma is a solution of selected aspects of cooling slaughterhouses. The main objective is the solution of mechanical cooling from the technical to the physical expression of nature and theoretical foundations comfort cooling.
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.
