Space heating and ventilation in a two-generation house
Kazda, Jan ; Hejčík, Jiří (referee) ; Charvát, Pavel (advisor)
This Master's thesis deals with the evaluation of a current state of two-generation villa and its following proposal of the optimization. Evaluation includes calculation of heat loss of a current state. Optimization is based on the reduction of heat loss in the building, pressure balance of the system, change of heat source and installation of balanced ventilation. Chapter describing regulation of technology follows and in conclusion indicative price for the whole suggested technology is calculated.

Analysis of fertility postponement and recuperation in Czechia based on the cohort approach
Ženíšková, Aneta ; Kocourková, Jiřina (advisor) ; Fialová, Ludmila (referee)
The main objective of this work is a cohort analysis of postponement and recuperation of fertility in the Czech Republic after 1960. Two methods were used for this purpose - basic benchmark model and relational model. The essence of the basic benchmark model is comparison of cohort cumulative fertility deviations between chosen benchmark cohort of women and other cohorts. The relational model is based on the cohort cumulative fertility deviations of cohorts from the chosen cohort related to the schedule of national standard deviations. The significant shifts in the timing of childbearing were revealed. While the first order is characterized by early fertility decline and subsequent significant fertility recuperation, the second order is characterized by a further decrease in fertility with slight recuperation. However, fertility of third and higher order continues to decline and has been found out. practically no recuperation. The second part of this work describes the respondents' answers to questions about timing of parenting. The main findings are that decisions about parenting is most influenced by whether respondents have a suitable partner, private housing and are financially secure. Most respondents postpone the birth of their first child due to the absence of a suitable partner, resp....

Heat sources for home heating
Drga, Pavel ; Špiláček, Michal (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with various heat sources for heating the family house. The first part of the thesis is a research, where the history of heating is summarized, energy sources and types of heating systems are divided and then traditional and unconventional heat sources used in domestic heating are compared. In the second part of this work are made designs of heat sources for heating a specific house. And in the end of the work is made an economic evaluation of the designs.

BMW Up-to-date SI-engines
Šroba, Roman ; Prokop, Aleš (referee) ; Dundálek, Radim (advisor)
The Bachelor’s thesis deals with modern BMW spark-ignition engines. It provides an overview of current automotive design solutions in gasoline engines. The work is focused on three main areas. The first part describes the latest and unconventional technologies used in current BMW spark-ignition engines. The second part is focused on design solutions in specific aggregates, their evaluation or comparison with contemporary competition. The last part describes the hybrid vehicles and the car manufacturer's response to emission standards with focus on the waste heat of a car.

Design of air heating system
Nagorskyi, Bogdan ; Baláš, Marek (referee) ; Kracík, Petr (advisor)
This bachelor thesis describes potential possibilities to substitute hot-water radiators with hot-air units with controlled air supply. Introduction part of the thesis describes basic thermal comfort factors. Subsequently, their application in traditional heating systems was performed. After that the issue of conditional heating efficiency of the original heating systems with the simultaneous application of ventilation was discussed, the analysis of which was the reason for the suitability of designing a new system of warm air heating with controlled air supply. The design of the hot-air heating system was performed for the living room of a typical panel apartment unit. During designing a new installation, the emphasis was put primarily on eliminating the main drawbacks of the hot-air heating system, namely the height distribution of the temperature layers. The system was designed in accordance with hygiene standards and its components include other air treatment elements. In the economic evaluation of the project, calculations of the possible implementation of the hot-air system and comparison with similar products commonly available on the market were made.

Health center
Dawid, Lukáš ; Hazucha, Juraj (referee) ; Donaťáková, Dagmar (advisor)
Diploma thesis designs a barrier free new building of medical devices – policlinic (health center) with 14 medical workplaces. Object has three floors and basement. The building is covered by a vegetation flat roof. Building of policlinic is based on strip foundations and load-bearing walls are made from sand-lime blocks. Horizontal systém is created like reinforced concrete ceiling and in the same way internal staircase. The building is design at passive architecture – have compact form, thick layer of insulation and airtight cover. The main glass facade is oriented to the sout. There is used heat recovery air conditioning and heat pumping for heating in building. Health center satisfy currently legislation.

Warm air heating and cooling the house
Rodková, Daniela ; Kašpar, Antonín (referee) ; Šikula, Ondřej (advisor)
This bachelor thesis deals with the inner climate optimalization of one - family house to which is associated private swimming - pool hall. In the one - family house there is designed air conditioning for hygienical air exchange, coller system for thermal stress removal during summer period and for heat losses coverage during winter period. In the private swimming - pool hall there is designed air conditioning for dehumidification and warm air heating of the hall. In addiction, there is designed floor heating in selected rooms.The source of heat for floor heating and TV heating - up is solved by new technology, which is, compared to classical boilers, environmentally friendly due to lowering CO2 emissions.

Ventilation Control Unit with Radio Time Synchronization
Barták, Jiří ; Šimek, Václav (referee) ; Tříska, Vít (advisor)
Project's primary objective was to create ventialtion control unit, which synchronizes its time through radio signal. Delivering power into fans is based on dew points calculated from data obtained on both sides of circumferential wall. The most important parts of this unit are microcontroller MC9S08DZ60, sensor SHT11 and DCF77 receiver. There is SD card socket on the inner printed circuit board for data recording purposes. I am working with the card on file system layer. The control unit uses USB socked as well to be able to communicate with PC. I have decomposed firmware of control unit into small modules at the start of development. Those modules are: MCU to MCU communication, USB communication, measuring temperature and relative humidity using SHT11 and extracting time information from DCF77 signal, all written in C. After these modules were tested, i have put them together. I have also written a PC application in Java. It is used to communicate with control unit and to process recorded data. Benefits of the control unit cannot be evaluated without long-term observation.
