Design of heat pump for space heating system
Panáček, Jaromír ; Elcner, Jakub (referee) ; Katolický, Jaroslav (advisor)
The bachelor's thesis contains design options of the heat pump for a family house. First part of the thesis deals with the basic types of heat pumps and their usage in the particular conditions. The description of the family house along with basic parameters for the design of the heat pump itself is presented in the second part of the thesis. Therefore the heat loss computation and the heat needs of the household are listed. Various designs of the heat pumps with basic properties according to the given house come afterwards. The conclusion summarizes the overall comparison of the individual types from the investments, operating expenses and the choice of the designed heat pump point of view. Mathematical basics are enclosed in the appendix.

Building physics assessment of the roof structure
Konopík, Petr ; Janík, Zdeněk (referee) ; Kalousek, Miloš (advisor)
This theses deals with a structural design comparison of heat insulations implementation in flat roofs in light of heat engineering. It also adverts to possible structural design in terms of heat insulations distribution in a flat roof. There are many materials options. I show the possibilities of material solution and also advantages and disadvantages of the single sealing materials at these layers. In the aplication part of this thesis I deal with possible concepts of insulation and solution for a specific roof of an older apartment house in Brno, where I conducted a constructive exploration. There was developed and evaluated a few options of solutions considering the heat insulator used. The following computational programs were used for the evaluations: TEPLO, AREA, CUBE 3D.

Solution of inverse problems in the area of material and heat exchangers
Kůdelová, Tereza ; Nechvátal, Luděk (referee) ; Čermák, Jan (advisor)
This bachelor's thesis deals with the dynamic behavior of heat exchangers which is described by the system of dierential equations. In this conection it includes a general information about necessary theoretical background especialy concerning heat transfer. Further, it mentions also the basic types of arrangement of heat exchangers that may occur in practice. The main goal is to answer the questions of controllability, observability and identifiability of the parameters obtained by solving corresponding inverse problem.

Assessing the Return on Investment in a Passive and Standard House
Krus, Tomáš ; Křivánek, Miroslav (referee) ; Hlavinková, Vítězslava (advisor)
The aim of this thesis is to compare economic investment in passive houses and conventional construction of a house. Furthermore, this thesis is focused on introducing problematics connected to construction of passive house, main characteristics, differences in used materials including review of advantages and disadvantages of their implementation. Assessment is based on return ability of initial investments generated by lowering operational costs. Main part of this thesis is aimed on compression of costs both before and in use of a house.

Heating of Family House-Heat Pumps
Choutka, Petr ; Čupr,, Karek (referee) ; Treuová, Lea (advisor)
The bachelor’s thesis contains a proposal of the heating of a detached house and a proposal of a suitable heating source. In the first part of the thesis there is an explanation of basic kinds of heating systems and types of heat pumps. The second part includes the description of the building, the determination of its basic parameters, the calculation of the heat loss and the heat demand for the whole household. Then a proposal of a heating system and a proposal of a suitable heating pump follow. In the end there is the comparison of the expected heating costs.

The Influence of Insulating a Block of Flats in Trebic on the Expenses Related to its Operation
Sedláček, Jiří ; Kosová, Jaroslava (referee) ; Čech, Josef (advisor)
This thesis solves assessment and project insulation of a block of flats in Trebic, on the expenses related to its operation. In the theoretical part of thesis are given the reasons for thermal insulation of buildings, requirements in terms of energy intensity of buildings, static and fire safety for insulation of buildings. In the practical part, the current state of the block of flats is evaluated from a thermal-technical point of view, three new thermal insulation options are proposed, their evaluation and their return time calculated.

Replacement of existing heat exchanger
Vaculík, Štěpán ; Toman, Filip (referee) ; Baláš, Marek (advisor)
This thesis deals with the possibilities of replacing an existing inefficient heat exchanger with a new one. In the first theoretical part a research of heat exchanger types, their operational features and suitable application is carried out. In the second practical part, the control calculation of the existing bundle heat exchanger with U-tubes is performed first, followed by the thermo-hydraulic design of a new bundle heat exchanger with straight tubes and a new plate heat exchanger. In the last part of the work, a comparison and assessment of which of the alternatives is the most suitable is made.

Energetická náročnost rodinného domu vytápěného dřívím
Vavruška, Martin
This bachelor thesis is concerned with determining the energy demand of heating of two variants of a terraced house. It deals with the original situation after construction of a family house and the situation after thermal insulation of perimeter walls, windows and doors replacement. The thesis compares these aspects: thermal losses, heat consumption for heating of the most commonly used heat sources, operating costs for heating and hot water warming, purchase costs for acquisition of these technologies and return on investment to these technologies.
