Proposal of rehabilitation of hot water network
Lžičař, Jakub ; Voltr, Aleš (referee) ; Raclavský, Jaroslav (advisor)
The bachelor thesis deals with hot water recirculation systems. It is mainly focused on the malfunctions that appear in the system. Firstly, the text elaborates general information about hot water recirculation systems, hot water distribution and its parts. The next part of the thesis describes materials used in hot water recirculation systems. Then the text deals with the malfunctions of hot water recirculation systems, design and assembly of the pipes. These chapters are followed by the case study. The case study helps to imagine the way of possible future reconstruction. The time schedule of the realization was attached to the bachelor thesis.

Rehabilitation of hot water network
Skůpová, Jana ; Raček, Jakub (referee) ; Raclavský, Jaroslav (advisor)
Abstract: The subject of the introductory part of this work is to create a basic overview about water heating networks. This is a familiarization with the operational parameters of the network, used materials, pipes, fixtures and objects and saving the pipeline. In another part of the work deals with the possibilities of rehabilitation-reconstruction and new construction, and underground and aboveground. At the conclusion of the work is handled by a specific proposal for the rehabilitation of feeder horkovodního Temelin nuclear power plant (JETe) into town Týn nad Vltavou. According to the investor's request was made to optimize the calculation of the dimensions of heavy pipe.

Piping systems for district heating
Malach, Tomáš ; Horák, Petr (referee) ; Hirš, Jiří (advisor)
In the first part of master thesis is presented general introduction to district heating system (DHS) and hydraulic calculation for DHS. The next part deals with analysis operation of DHS and the pressure diagram for certain time interval. Subsequently, the thermohydraulic characteristics for the hydraulic main branch (comparing manual calculation with software calculation) and also the selected thermal and hydraulic characteristics for the whole DHS are shown. The last part is focused on the determination of the amount of heat supplied based on the ultrasonic flowmeter and the temperature probes. Subsequently, the computer simulation is also carried out, aiming at approximating the real heat supply from heat source to solved thermal network in winter.

Energy assessment
Farkhutdinova, Iuliia ; Uher, Pavel (referee) ; Horák, Petr (advisor)
My thesis focuses on the preparation of an energy assessment. The studied object is a residential building located in Prague. In the theoretical part I focus on a detailed analysis of the concept of central heat supply and its importance in today's energy environment. I look in more detail at the key benefits of this system and its role in the current energy context. The computational part contains an energy assessment that evaluates the building in two variants with different heat sources: central heat supply versus air-to-water heat pump, together with the proposed measures. Both variants are evaluated in terms of energy efficiency, economics and ecology. In the experimental part, I deal with thermographic measurements of the investigated residential building and the subsequent evaluation of the measured data.

Multifunctional building heating
Kukla, Zdeněk ; Počinková,, Marcela (referee) ; Adam, Pavel (advisor)
The objective of this bachelor thesis is proposal heating and hot water for Multifunctional building. Heat supply is realized with a hot water transfer station in basement of the building. The heat source is a system of central heating. In the building are proposed panel radiators. In the transfer station is proposed accumulation water heater.

Heating systems and heat distribution in apartment buildings
Rušín, Marek ; Formánek, Marian (referee) ; Počinková, Marcela (advisor)
Content of this diploma thesis is to describe functioning of heat meters, billing of measured values and aplication of this knowledge on existing building. Apartment building have five storeys and a basement. Every storey have two apartments. Design of a heating system is divided into two separete variants. First variant consist of two gas condensing boilers as source of heat and second variant consist of heat transfer station.

Systems of energy efficient buildings
Šlampová, Kateřina ; Horák, Petr (referee) ; Počinková, Marcela (advisor)
The topic of this diploma thesis is systems of energy efficient buildings with a focus on the building envelope. The first theoretical part describes the quantities that we consider when designing the building envelope. The second half of the theoretical part is with reference to the experimental part of the thesis focused on a special type of vertical perimeter structure, namely walls with live vegetation installed from the outside of the structure. The second, practical part of this work, deals with the design of heating and hot water supply for a multifunctional building. The design is elaborated in two variants - heating by means of radiators in the first variant and in the second variant by means of floor heating for residential units of the solved building. The third part define an experiment, which had the task of comparing the measured quantities on two types of vertical perimeter structures, namely a structure with growing greenery from the outside and an identical structure only without a layer of greenery. At the same time, the task was to check the possible influence of the applied greenery on heat losses, and thus the design of the heating system.
