Warm air heating systems in family houses
Jankůj, Josef ; Hejčík, Jiří (referee) ; Košner, Jan (advisor)
The aim of my work on the theme “Warm air heating systems in family houses” is to summarize used systems, it´s individual components, pass judgment on preferences and shortcomings of this systems. First part is oriented on general familiarization with air rating, examination advantages and disadvantages against classic warm-water system. Second part put mind to elementary systems of airing buildings, their parting and identification with their particular principle.

Comparement of results from infiltration tests
Blahut, Dominik ; Mazáč, Petr (referee) ; Duchan, David (advisor)
The aim of this thesis is to compare the results of water infiltration from field tests, from laboratories and from numerical modeling at two selected locations. The first objective is the search procedure and the description of both sites and its adjacent areas. Further work continues with infiltration field tests using ring infiltrometer, at first theoretically for each method, and then practically with own personal measurements in the field. Further from the collected soil samples the measurements are performed in the laboratory, first in the permeameter, and followed by the grain size distribution test, from which the hydraulic conductivity is derived by using empirical formulas. At last the numerical modeling is used and all the results are compared. In the final phase of thesis the recommendations are given for infiltration at various locations and comparsion of the infiltration methods.

Operation of rain gutters
Chotová, Tereza ; Balas, Jan (referee) ; Hluštík, Petr (advisor)
The diploma thesis is divided into two parts. The first theoretical part focuses on rain gutters, their distribution, operation and cleaning. The pollution, pre-treatment of rainwater and rainwater management are alco described here. The second practical part includes testing of selected street rain gutters in the institute of municipal water management laboratories (VHO). Furthermore, these rain gutters are compared and evaluated according to these criteria: filter construction, amount of captured material and cleaning system.

Analysis of the mutual relationship between two methods of field measurement of water infiltration into the soil
Larišová, Lucie ; Kriška,, Michal (referee) ; Kameníčková, Ivana (advisor)
This thesis deals with the theoretical description of the infiltration process and field measurements of infiltration in the cadastral territory of Bohaté Málkovice. The research work carried out in 2011 in an experimental area on Haplic Chernozem/FAO, medium-heavy loam soil. The experimental area was divided into two parts, the topsoil layer on these surfaces was processed by both classic and minimization technologies. The plots were sown by spring barley. The applied measurements of water infiltration into the soil were two-cylinder method and MiniDisc. Within the vicinity of the infiltration experiments with intact soil were collected samples for laboratory determination of saturated hydraulic conductivity. From the field measurements and laboratory experiments were determined values of hydraulic conductivity (saturated and unsaturated), and other infiltration characteristics, the cumulative infiltration and infiltration rate. To evaluate the infiltration of the heats was used three-paramether Philp type equation that provides a good estimate of saturated hydraulic conductivity. For the evaluation of the MiniDisc there was used the Zangova method that provides the unsaturated hydraulic conductivity. The laboratory evaluation of the saturated hydraulic conductivity was compared with the estimated values obtained from the field measurements. The values of the saturated hydraulic conductivity from the laboratory measurements are closely comparable with estimates obtained from the steady infiltration rates from the field experiments. The research results also showed that medium-heavy loam soil, when being processed by minimization including modification of the soil surface by digging, have a positive effect on the infiltration of water into the soil. This fact leads to a higher protection plants in the vegetative period and improvement of the retention and storage capacity of soil.

Assessment health/quality of the soil near the village Bohaté Málkovice
Suchá, Kateřina ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
Diploma thesis evaluates quality and healthiness of the soil health located close to Bohate Malkovice focusing on changes in both physical and chemical characteristics of the soil in time. The theoretical part describes physical, chemical, and biological parameters of the soil. Selected physical parameters are structure, texture, determination of measured weight, bulk density of the soil, porosity, actual volumetric water content of the soil, aeration, saturated and unsaturated hydraulic conductivity, infiltration, and colour. Chosen chemical parameters are pH, carbonates, soil electrical conductivity, and humus content. Picked biological parameters are microbial biomass, respiration, nitrogen content, and weed infestation. The practical part analyses selected indicators of quality of the soil from the location of the experiment close to Bohate Malkovice. The area under evaluation has been treated using reduced tillage for long term. The practical part is based on the laboratory examination of disturbed and undisturbed soil samples taken between years 2016 and 2018. Based on outcome results we can evaluate the quality of the soil considering plants growth, development, and soil fertility.

Rainwater infiltration
Kračman, Martin ; Macsek, Tomáš (referee) ; Hluštík, Petr (advisor)
The aim of this bachelor´s thesis is to define legislative options of infiltration, retention and drainage of rainwater for household in Czech republic. Thesis describes not only rainwater, but also waste water, the quality and usage of them both. Furthermore, the?amount of usable grey water in household is defined. Then the systems for retention waste water and rainwater are desribed as well as technical principles of their design and purification of rainwater. In the final part od this thesis, the systems for usage of?rainwater and grey water are designed. Finally, the designed systems are evaluated and their feasibility is assessed.

Model solution for rainwater management in selected types of residential buildings
Šoustal, Michal ; Rajnochová, Markéta (referee) ; Ručka, Jan (advisor)
The bachelor's thesis contains a model solution for rainwater management, where certain measures are proposed for selected types of residential buildings. Its aim is to propose the economic use of precipitation for the benefit of the population and the environment. The introductory part is acquainted with water supply networks, rainwater quality and legal legislation. The theoretical part describes the individual infiltration and retention devices that are used today. The following are mathematical methods and procedures that have been applied in the research. The theoretical part also describes possible subsidy programs for the use of financial support for rainwater capture. The research began with a survey and then an analysis of the public and private space in which the buildings are located and the remaining data were performed from ČSN standards. In the practical part, hydrometeorological calculations were performed, then according to the identified legal requirements, measures were subsequently proposed for implementation. The indicative budget of the proposed measures was prepared by calculating aggregated RTS prices. Followed by subsidy contributions, which may cover part of the costs of the measures created.

Heating of the kindergarten
Matůšů, Ondřej ; Komínek, Petr (referee) ; Počinková, Marcela (advisor)
This bachelor's thesis theme is about airflow ways of gas boilers described in the theoretical first part. The second part contains heating process of a kindergarten. Object is two-storeyed and newly reconstructed. Capacity of this object can contain 100 children placed into four classes. Heat source for this object is set of two gas condensing boilers. In this object are used panel radiators covered by wooden frames. In the object is partly used flow-through ventilation operated by ventilating units.
