Solar collectors with vacuum tubes
Petruška, Bohumil ; Katolický, Jaroslav (referee) ; Jaroš, Michal (advisor)
This thesis deals with solar collectors with vacuum tubes. The first part is focused on describing the function of the collectors, comparing with other types of solar collectors followed by specifications of their usage. Another topic is the heat transfer fluid that is used for transmission of heat, and therefore it is an important component of a collector. The last part deals with an application concept of use of a vacuum tube solar collector, including basic energetic and economic calculation.

Energy system for energy independent object
Kaňovský, Jiří ; Pěcha, Jiří (referee) ; Mastný, Petr (advisor)
This bachelor‘s thesis deals with a design of energetic system for energetic independent family house. There are default parameters for the house defined, and an impact of house's placement in nature on thermal energy loss and on thermal energy gain due to solar radiation is described at first. There are daily diagrams of thermal energy consumption for common and heating periods derived in this thesis. An energetic system producing electric energy using photovoltaic solar panels which are placed on the house's roof is designed based on the diagrams. The thesis also introduces basic types of island energetic systems. The objective of this thesis is also a design of energetic system for heating-up (TUV) using a thermal pump, fireplace and solar collectors.

Design and comparison of a space heating systems with different heat sources in family house
Kamenský, Petr ; Elcner, Jakub (referee) ; Katolický, Jaroslav (advisor)
Diploma thesis deals with design and comparison of heating systems. In diploma thesis is designed system with gas condensing boiler, system with heat pump and system with gas condensing boiler for heating and solar collectors for heating of hot water. Content of this thesis is calculation of house heat loss, design of radiators, design of heat systems including a check of protective components, regulation with the help of thermostatic radiator valve, calculation of economical evaluation and creation of design documentation. Design is made for systems with unified temperature fall 55/45. For the variation with heat pump is computed a possibility of using the heat pump as an univalent or bivalent heat source. In the analysis of costs is considered a usage of natural gas for heating and warming of hot water with a condensing boiler, annual consumption of electric energy for operation of electrical appliances in household, consumption of electric energy for operation of heat pump for heating and warming of hot water and consumption of electric energy for warming of hot water in case of system with solar collectors. In the final evaluation a pay-off period is determined.

Solar heating tap water
Kysel, Stanislav ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
Solar heating tap water In this bachelor´s work I engage in problems and concept of solar system for preparing warm supply water. For heating – up has been used a bivalent system complemented by electric heating inlet. The calculation has been intent on concept of collector area size and size of the supply bin.

Heating the building for youth and free time
Horák, Jiří ; Počinková, Marcela (referee) ; Horák, Petr (advisor)
The content of this thesis is the treatment of heating of a multipurpose building for youth and leisure time in Letovice, Blansko district. The building has three floors with a total built-up area of 1003 m2. Thesis solves a design of the heating system of the first floor including solution to the boiler room for heating the whole building. The boiler room is located on the ground floor. Pellet boilers are designed for heating purpose. Solar system is designed for preheating drinking water. Room ventilation in building is designed as a natural.

Low-energy building of boarding house in Chlumětín
Vtípil, Jan ; Blasinski, Petr (referee) ; Počinková, Marcela (advisor)
The master thesis deals with the design of environment friendly boarding house, which is located on a hill in a small village called Chlumětín. There are designed renewable energy sources, such as solar collectors or fotovoltaic panels. The first part deals with the design and layout of the boarding house. On the ground floor is solved, the design of the kitchen according to hygienic requirements, the design of the premises for guests with barrier-free toilets. In the attic are designed guest rooms including barrier-free room. The second part deals with the simplified design of building services. It includes rainwater management, mechanical ventilation with heat recovery, lighting, cooling and heating. The third part deals with the detailed design of heating in the building. It includes design of radiator power, pipe dimension, power of wood-gas boiler, storage tanks, pumps, etc.

An apartment building with the use of renewable energy
Poul, Jiří ; Horká, Lucie (referee) ; Vyhlídalová, Karolína (advisor)
The aim of the master's thesis is to propose a suitable heating system and hot water supply in two variations for a residential building in Prague. The residential building is constructed on a sloping plot, consisting of one underground floor and three above-ground floors. The first underground floor accommodates a collective garage and cellar compartments, while the above-ground floors house 18 apartments. The heating system is based on hot water circulation, with heat distribution to the heated rooms facilitated by panel radiators. The first variation for hot water supply involves a storage water heater, and the second variation includes the integration of solar collectors. The theoretical part focuses on introducing solar collectors, exploring their types, placement, and prevalence worldwide.

Design of heating system for low-energy family house
Kytýrová, Zdeňka ; Hejčík, Jiří (referee) ; Košner, Jan (advisor)
This diploma thesis deals with the design of a heating system for a "low-energy" house. It is conceived as a low temperature system using a combination of radiators and underfloor heating. The design is supplemented with a calculation of heat loss, a proposal of needed components, a scheme of the system and means of regulation. The second part solves the heat source selection. A solar system with vacuum tubes is used as the primary source. The second one is an electrical water heater located in the accumulation reservoir for the hot domestic water. Necessary calculations for the design of the solar system, together with a scheme and means of regulation, are enclosed in this section.
