The issue of energy-efficient home heating
Števanka, Kamil ; Hrnčířová, Michaela (referee) ; Baláš, Marek (advisor)
The bachelor´s thesis focuses on the issue of energy-efficient home heating. In the first part principles of energy-efficient house construction are described. In the second part different kinds of heating devices are overviewed. Various systems combining devices from second part are compared in the last part.
Assessment of investment in heating house
Zdražil, Pavel ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
The bachelor´s thesis deals with economic evaluation of investment in insulation and heating and resulting operation of boilers in a family house. The calculation of thermal design power, which is needed for heating, was made according to norm ČSN EN 12831 for the house in actual state without insulation. Further were suggested two options of insulations and modernization of windows, for reduction of heat loss. Then was calculated the thermal design power for the two new options, again according to norm ČSN EN 12831. Next were presented possibilities of heat sources. For the specified family house was chosen a gas boiler in classical and condensing implementation for all three variants of insulation. These all options have made six variants which were compared together and evaluated. In the conclusion were excluded four variants economically disadvantageous and was chosen one of the final two variants as the best suggestion for the specified family house.
Heat exchanger design
Zdvyhal, Marian ; Hrnčířová, Michaela (referee) ; Baláš, Marek (advisor)
This bachelor thesis solves design of a heat exchanger for hot water boiler with gasification chamber for preheating the combustion air with the heat of the combustion products. Calculation values were experimentally measured. Thesis contains brief description of the shell and tube heat exchanger, stoichiometric combustion calculation, geometrical dimensions design of the heat exchanger, pressure loss and thermal performance calculation. It also includes drawings of the designed exchanger.
Proposal heating system of the house
Češla, Martin ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
The bachelor thesis aims to calculate the heat losses of a detached house, propose the temperature gradient and suggest the radiators for the current gas boiler as well as for a new condensation boiler. The thesis also contains the schematic drawing of the radiators in the plan view. Eventually, the thesis deals with the calculation of the radiators replacement and determinates the payback period.
Proposal heating system of the house
Minařík, Petr ; Hrnčířová, Michaela (referee) ; Baláš, Marek (advisor)
This work includes the calculation of heat loss and design of the house heating system. To determine the heat loss of the family home will be used standard ČSN EN 12831. Heat loss will be calculated for each room. Radiators are designed to individual rooms for different temperature gradients and by heat losses. The lounge is designed underfloor heating. For heating are designed three different heat sources. One source of high-temperature and low-temperature two sources. The investment costs of the heating system will be evaluated finally.
Assessment of investment in heating house
Baláži, Martin ; Šnajdárek, Ladislav (referee) ; Baláš, Marek (advisor)
Bachelor thesis assesses the ways in which you can reduce the cost of heating a house. After the calculation of heat loss, there are chosen appropriate thermal-insulation applications to reduce heat transmission through the facade, roof and windows of the building. In the next step is chosen more efficient and environmentally friendly way of heating. Return on investments of selected applications, are shown graphically.
The issue of energy-efficient home heating
Kollár, Ľubomír ; Hrnčířová, Michaela (referee) ; Baláš, Marek (advisor)
Low-energy houses are becoming more common and requested. The Bachelor's thesis focuses on heating and ventilation of low-energy houses. The beginning chapters describe and explain basic principles of these buildings and basics of air-handling and heating systems. The main part of the work overviews contemporary heating and ventilation systems while pointing out their advantages and disadvantages. The work includes a design of heating and ventilation of low-energy house.
Use of renewable energy sources for family house heating
Jež, Dalibor ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
The content of this bachelor’s thesis is the technical research focused on renewable sources of energy used for family house heating. The thesis is divided into several parts. The first part consists of general information, characteristics and dividing of each renewable sources. There are also their advantages and disadvantages. The second part of the thesis is focused on suggestion of concrete systems suitable for family house heating and is supplemented with their comparison.
Surface condenser
Kloda, Michal ; Baláš, Marek (referee) ; Šnajdárek, Ladislav (advisor)
The bachelor’s thesis dealing with surface condensers is split into three main sections. The first section describes surface condenser, problems of heat transfer during condensation and a method of determining the heat transfer coefficient using the methods HEI and VTI-CKTI. The second section deals with the main construction elements and their materials, where the special attantion is paid to condenser tubes materials. In the third and the last section, the simplified thermodynamic design of surface condenser for given parameters is shown.
Steam ejector pump
Třináctý, Jan ; Baláš, Marek (referee) ; Šnajdárek, Ladislav (advisor)
The aim of this theses is to do search about maintaining vaccum in surface condensors and subsequently propose basic dimension of one stage steam ejector. The first part deals with the issue of vacuum. The following part is dedicated to description of various types of vacuum pumps. Hence it describes the principle of operation of each pump as well as their output. The following part deals with vacuum and vacuum technology in the field of power engineering. This part is dedicated to those types of vacuum pumps that are used in power engineering, especially to steam ejectors which are most widely used. The final part is addressed to the design of single stage steam ejector. This part contains the calculation of pump dimension. The conclusion evaluates the design of one stage steam ejector.
