Implementation of the air-ground heat exchangers in condition of the Czech Republic
Macenauerová, Tereza ; Musil, Zdeněk (referee) ; Kolbábek, Antonín (advisor)
This work presents the implementation of ground heat exchangers for air-conditioning systems of buildings in the Czech Republic, especially in south Moravia. The purpose is to find basic information about specific devices - such as the type of heat exchanger, material of pipeline, the method of suction (filtration), outlet of condensate, etc. These are parameters that investor can decide before the realization. Exercise equipment is dependent on the parameters that investor can not decide (eg. type of soil, disposition of land, surrounding climate). The work is based on a questionnaire study (part of junior project FSI-J-12-24) form 2012 which was solved with concrete owners of realized devices. A part of the ground heat exchangers comes from the implementation of energy-efficient houses KARON s.r.o. company, the basic parameters of the these exchangers are provided by its managing director Ing. Stanislav Karasek. Other devices have been traced in the database of passive houses in the Czech Republic - managed by the Passive House in Brno. The work summarizes some of knowledge of owners, shows the most often used types and values the importance of proper design of the whole device.

Energy conservation in ventilation of buildings
Sláčík, Ondřej ; Kolbábek, Antonín (referee) ; Charvát, Pavel (advisor)
This bachelor’s thesis deals with various forms of building ventilation, especially energy conservation in ventilation. The first part focuses on the factors that influence the quality of indoor environment. The second section describes the concepts of ventilation and basic distribution of different ventilation methods. Another section deals with heat losses associated with ventilation. The last part deals with the various measures that leads to reduction of energy losses of ventilation, it is mainly controlled ventilation based on CO2 and heat recover.

Heating and ventilating of low-energy and passive houses
Jankola, Mario ; Musil, Zdeněk (referee) ; Jaroš, Michal (advisor)
The Bachelor's thesis focuses on heating and ventilation of low-energy and passive houses. The beginning chapters describe and explain basic principles of these buildings and basics of air-handling systems. The main part of the work overviews contemporary heating and ventilation systems while pointing out their advantages and disadvantages. The last chapter consists of realistic blueprint for low-energy family house, including specifications on heating and ventilation systems, as well as evaluation of their efficiency.

Heat recovery ventilation unit
Balák, Jan ; Fišer, Jan (referee) ; Hejčík, Jiří (advisor)
This bachelor thesis will inform readers about residental buildings ventilation posibilities, higyenical standarts of ventilation, sorting of heat recovery units used for heat recovery in residental buildings. Moreover, specific house will be choosen and its ventilation demands will be calculated. Than conveniend ventilation and heat recovery equipment will be search, because of optimalization of ventilation and heat losses.

Analysis of different means of heat recovery in ventilation
Dvouletý, Tomáš ; Krejčí, Vladimír (referee) ; Charvát, Pavel (advisor)
Bachelor´S thesis contains summary and expplanation of basic ideas related with topic of analysis of different means of heat recovery in ventilation like efficiency, economy of using atc. Main part of the work is dividing varied ways of heat recovery based on kind of used heat exchanger. There are description of principle of heat transfer with illustrative pictures including some other informations related to each heat exchanger. After that there is comparation of heat exchangers based on efficiency, enthalpy transfer capability and safety. This part also includes summary of advantages and disadvantages. Finaly there are brief report of market with heat exchangers in Czech republic and some others ways how to use gained heat.

Air heating in the sport hall
Janková, Martina ; Ell, Jiří (referee) ; Rubina, Aleš (advisor)
The main goal of the bachelor’s thesis „name“ is designing an air conditioning device for a sport hall and its social facilities. A solution must fulfill functional, hygienic and operational requirements for the specific microclimate of sport halls. The device is designed to cover heat losses in winter as well as for cool down heat gains during summer. At the beginning a microbiological and an aerosol microclimate in an air conditioning are considered. In the next part of the thesis the required performance of the device is calculated. In the third part is the documentation of both devices is attached.

Hot air airconditioning of the flat house
Viktorin, Michal ; Tesař, Zdeněk (referee) ; Rubina, Aleš (advisor)
The brachelor's dissertation is divided into three parts: theoretical, computational and design. The theoretical part is focused on heat recovery systems in air through regenerative heat exchangers. The calculation and project part deal with the design of air ventilation in flat house. The building is used for permanent housing and is divided into thirteen functional units. A technical solution is developer with regard to the statutory hygiene parameters of air and thermal comfort microclimate under applicable legislation of the Czech Republic in 2015. In addition, it will provide the ideal microclimate for housing and improve the quality of life in the building.

Ventilation of the production hall background
Hajn, Daniel ; Blasinski, Petr (referee) ; Rubinová, Olga (advisor)
Bachelor thesis describes the design of air-conditioning for production hall background in the city Humpolec. The building is designed to work with wood. The administrative part of the hall is divided into four separate sections each is serviced by its own device. The main task is to ensure the required exchange of fresh air and further ensure coverage of heat gain in the summer. The theoretical part describes the types of air-conditioning units and their components. Calculation and design part addresses the specific design of air-conditioning equipment for the administrative part of the buildings.

Detached house with pet shop
Meliš, Lenka ; Kalánek, Jiří (referee) ; Ostrý, Milan (advisor)
The subject of this bachelor theses is a design of detached house with pet shop attached to it. It is situated in Klobušice, which is a suburban part of the city of Ilava. The site includes parking space for three cars for shop customers and one for occupants. The house is two storey building without basement. It is divided into two functional areas, the pet shop area and the living area. The living area is designed for four people. Living area roofing is designed as a shed roof with 8° slope and the pet shop area is covered by vegetative roof with 3° slope. For load-bearing walls the Silka sand-lime blocks are used insulated with thermal insulation of mineral wool mounted on the exterior side of the wall. The house is built on foundation slab, which is laid on a layer of foamed glass brash. The house is designed as passive house including ventilation with heat recovery. The theses contain project documentation for the construction and an essay - Structural parts and building evaluation in terms of thermal engineering and acoustics requirements.
