Heat pump in cooperation with PV for family house
Drašar, Vojtěch ; Vrána, Michal (referee) ; Mastný, Petr (advisor)
The bachelor thesis deals with the design of a heat pump in cooperation with a photovoltaic system for a family house. The theoretical part describes the principles of the heat pump and the photovoltaic system. The thesis presents the methods of operation of the heat pump, the principles of building cooling, the connection of the PV system to the grid, or the methods of storing excess energy. In the practical part, the consumption of a typical family house has been determined by means of typical supply diagrams. The consumption is based on hourly statistical values for the year 2021. From the obtained values a pump was designed. Another objective of the work was the placement of photovoltaic panels on the roof. The power plant is considered as a hybrid, in order to maximize the consumption of the energy produced and the use of energy at the point of generation. For this, a battery system was also designed. The work includes an energy and economic evaluation, including the payback of the combination. For the economic evaluation, a subsidy from the New Green Savings 2021+ program was considered. The proposed solution has applications in both renovation and new construction, where the emphasis is on minimizing air pollutants and also the use of ecological resources.

Studies on gas microturbine operation
Horník, Jan ; Bobák, Petr (referee) ; Vondra, Marek (advisor)
The bachelor thesis is focused on the study of the gas microturbine. Theoretical part makes the reader familiar with gas microturbine. Practical part is focused on its use in the field of industrial laundry. Analytical part includes the design and execution of measurement, which is followed by necessary calculations. On the basis of it is proposed several uses of combustion from microturbine. The final output of this work is financial balance for each of those uses, where can be seen return of the investment.

The impact of executing new thermal insulation on an administrative building in Blansko on the expenses associated with its operation
Kopřivová, Petra ; Bradáč, Albert (referee) ; Čech, Josef (advisor)
The topic of the diploma thesis „ The impact of executing new thermal insulation on an administrative building in Blansko on the expenses associated with its operation“ is a draft and appraisal of four variants of thermal insulation of the building (EPS, EPS G, Mineral wool, Phenolic foam). It deals with an actual building situated in Blansko. All the variants are projected according to the same technical specifications (thermal transmittance) and their thermal parameters, technical parameters and the rate of return have been assessed. The assessed building (The A building) is at rectangular shape. It has six above - ground floors and a basement, it contains mainly administration sites. The construction system is concrete frame, which has curtain wall made of perforated blocks with thickness 250 mm. The building has got reinforced concrete floors, the roofing is made of double-skin roof construction. The supply for heating is a separate gas boiler room.

Determining the amount of economic rent for single-family house in Brno
Kubásek, Petr ; Gardášová, Alena (referee) ; Klika, Pavel (advisor)
The objective of the thesis is to determine the economic rent amount for a family house located in Brno. The concept “economic rent” refers to the amount of payment that brings adequate profit to the landlord. First, all the factors are identified that compose cost rent, i.e. the rent of mere providing and maintaining a property. The main variable is represented by the reproduction value of a dwelling. For the purposes of this thesis, the reproduction value is determined using the cost method (in agreement with the evaluation regulation). Second, the capitalization rate is determined so that an adequate profit could be calculated. The following two methods are employed: the surcharge method and the method of comparison with the financial market. The thesis presents seven alternatives of an economic rent, depending on the interest rates. Lastly, the calculation of the rate of return is performed, along with a correctness test of the calculation of the economic rent amount.

Budisov-Biomass heating plant
Petrovský, Jiří ; Baláš, Marek (referee) ; Fiedler, Jan (advisor)
This dissertation contains a comparison of the real possibilities for heating reconstruction and TUV reheating in three public buildings (located nearby one another) in Budišov township, with resulting recommendations of the best options for local operating conditions. The dissertation contains calculations of heating requirements for particular buildings, a generic theoretical part which summarizes basic data concerning long-term fuels (biomass and natural gas), proposals for technical solutions to heating sourcing concerning these fuels and its prospective distribution from a central boiler house, and its reciprocal comparison from the perspective of the economics of actual realization and operation, and from a perspective of fuel availability and ecology.

Proposal of the digitization of analog mammography centers
Večeřa, Martin ; Zavadil, Pavel (advisor) ; Vachoušek, Jaromír (referee)
1 Abstract The aim of this bachelor thesis is to propose digitalization of an analog mammographic center, its technical realization in its entirety including implementation, to compare digital and analog mammography and to evaluate its economic costs in a private senological center accredited by the Ministry of Health of the Czech Republic for breast screening. The economic return is expected to be in 15 000 examinations per year. From the calculations of annual costs and revenues the expected net profit of the mammographic center is 1 497 600 CZK. After 8 years of device-service the profit is 11 980 800 Kč. The fundamental lack of digital mammography is its price which is in comparison with the analog mammography much higher. This is an obstacle to current centers. Quality and rapid diagnostics of asymptomatic women with the elimination of false negative findings speak for digitizing the mammographic screening centers. In the future we can expect an extension of digital mammographs. Keywords: digital mammography, analog mammography, digital, mammograph, breast screening, economic return, price, mammography center, senological center
