Heat recovery
Dužík, Vojtěch ; Rubinová, Olga (referee) ; Počinková, Marcela (advisor)
The aim of this diploma thesis is to theoretically, practically and experimentally explore different ways of waste heat utilization in the building industry. The work is divided into three basic passages. In the first part I analyze the theoretical nature of the various physical processes in recovery and is there a practical use. More emphasis is placed on heat recovery from wastewater, as I am using this way of recuperation in other parts of this diploma thesis. In the second point, I apply the use of heat from waste water when designing a technical solu-tion for the reconstruction of the heating system of the clinic. The design is solved in two variants. The first suggested location lokali- them, recuperative, shower exchanger operation rehabilitation, bath and massage. In the second variant, central recovery is envisaged using a heat exchanger in the accumulator well and water-water heat pump. Based on the technical and economic evaluation, the first option was selected. The second variant is ineffective and remains only in the case study. In the last section, I experimentally investigate the thermal efficiency and the relative savings of the heat exchanger, which is designed in the first variant of the second part. Measurement, processing of results and evaluation I made for laboratory conditions and for real conditions with the showering person. Finally, I appreciate the eco-nomic benefits of this facility.

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.

Hot water quality for heat
Snášelová, Tereza ; Hirš, Jiří (referee) ; Počinková, Marcela (advisor)
The diploma thesis focuses on assesment of water quality in heating systems. The experiment includes description of used methods and meters as well as analysis of collected samples. The theoretical part describes selected water properties, quality meters and sources of heat according to the material of their heat exchanger. This thesis processes design of heating system and hot water preparation for complex of administration buildings. The project includes calculations of heat losses, system proposal and two versions of possible heat source. The first version offers solution with condensing boiler with heat exchanger from stainless steel, while the second version uses condensing boiler with heat exchanger from aluminium and silicon. Both versions have their own solution of safety equipment and water treatment.

Heating of Trade Center
Jankes, Filip ; Rubinová, Olga (referee) ; Horák, Petr (advisor)
Thesis aim was to propose a heating of trade center. Proposing were only a side rooms of the building away from the main shopping area. The theoretical part deals heating surface. In the computation section are perform calculations, designs and sizing of the heating system and all other necessary equipment. The project part contains the technical report and drawings. The building of the trade center is mostly single storey only with a few extensions of the second floor. Near the object stands two outbuilding for technical equipment and water tank.

Heating of a residential building
Kocandová, Karolína ; Čupr, Karel (referee) ; Treuová, Lea (advisor)
The objective of this bachelor thesis is to design heating and hot water production in an apartment block. The theoretical part is based on the topic of the preparation of hot water. The calculation part includes the calculation of heat losses, the suggestion of heat transfer surfaces, the dimensioning of pipes and the suggestion of the heat source for heating and warm water. Gas condensing boilers are applied as a heat source. They are located in the technical room. The preparation of hot water and the heat consumption measurements in flats are solved by district heating substations.

Heating and preparing of domestic hot water via solar system
Lustigová, Andrea ; Adam, Pavel (referee) ; Horák, Petr (advisor)
The aim this bachelor thesis is the design of heating and preparing of domestic hot water via solar system. The theoretical part deals with the solar systems, solar collectors and stagnation of solar systems. The second part deals with a separate proposal heating and preparing of domestic hot water in a family house. As a heat source was proposed condensing boiler and solar collectors. The hot water is also ensured condesing boiler and solar collectors. The third part consist of a technical report and drawings heating of the specified object.

Heating system of a Low-energy house
Jankola, Mario ; Pech, Ondřej (referee) ; Katolický, Jaroslav (advisor)
This master’s thesis pertains to heating practices of low-energy houses using a heat pump (example 1) and low-temperature condensing boiler (example 2). The first part of the work contains calculations of suggested building’s heat efficiency and of under-floor heating. The second part of the work includes estimates of seasonal heating factors for construction with a heat pump. Based on the comparison: both of these heating systems are recommended; the capacity of the warm water container is established; and safety elements are chosen. Furthermore, a system of regulation for warm water heating is determined, and a curve of equithermal regulation for heating is calculated. Both of the recommended heating possibilities include calculations of costs of supplies and manufacturing, as well as blueprints for construction.

An Apartment House - heating
Vyhnánek, Jan ; Čupr,, Karel (referee) ; Treuová, Lea (advisor)
Bachelor work consists of theoretical and numerical part. In the theoretical part deals with various methods of heating in apartment buildings. The numerical part deals with individual part of the heating system in the apartment building. For heating the apartment building was chosen central heating system with indirect hot water. As the heat source was chosen gas heat pumps in combination with condensing boilers.
