Pasivní bytový dům / Passive apartment building

Čejka, Radek January 2016 (has links)
The aim of the thesis is the proposal and the preparation of project documentation for the construction of passive residential building on a plot number 1691/96 cadastral area of Černovice in a Brno city. The residential building will be built in a sloping terrain. It is a five-storey residential building with one floor below ground. The house has 16 residential units and is designed for a maximum of 40 people. Two of the units are designed as a wheelchair accessible. The skeletal staircase of a building is located outside the main building. The residential units are connected by porch. The porch is built from a steel skeleton and is standing outside the main building. At the south side of building is free standing steel construction used as balcony for residential units. Perimeter wall is made of sand-lime blocks which are insulated by graphite expanded polystyrene. Perimeter wall of basement is made of permanent formwork filled with concrete. The wall is also insulated with extruded polystyrene. The ceilings are made of prestressed concrete panels Spiroll. The supporting roof structure is made of wood trusses. The roof is pitched and the roof deck is designed vegetational. The building is ventilated using forced air handling unit. Heating and hot water is provided sources: pellet boiler and photothermic panels. The apartment house is designed with regard to energy saving as passive. Emphasis is placed on a compact building envelope, simplicity of shape, air tightness, low heat loss and high solar gain arising due the building orientation to the cardinal directions.

Vliv obálkových konstrukcí budovy na výdaje spojené s jejím provozem / Influence of the building envelope structures on the expenses associated with the operation

Baďurová, Monika January 2016 (has links)
The thesis deals with the assessment of the current proposal for pension envelopes along with proposing alternative plans with emphasis on reducing heating costs. The first section describes the types of buildings according to heating demand and output energy performance of buildings. Work also deals with a list of different variants of thermal insulation materials and design options outer insulation of the building envelope. It outlines fire characteristics of building materials and options of construction budget. The second part is devoted to a specific pension house in the Old Rejviz for which there are designed in three variants of insulation. These variants are then reviewed in terms of thermal insulation. Through research will bedetermined price of implementation of proposed insulation options together with the costs of operation of the pension. The conclusion is to evaluate each proposed version of insulation of the building envelope associated with the economic return on investment.

Tepelné čerpadlo vzduch - voda / Air source heat pump

Ratsam, Pavel January 2016 (has links)
The master's thesis is focused on heat pumps as a device using sources of a low-potential heat for building's heating. There are individual types of these devices characterized by a principle of operation and used media. Main focus of this thesis is a design of a compact air-water heat pump for the company PZP HEATING a.s. consisting of a cooling circulation’s design and individual components of this circulation. Finally there is a proposal of the heat pump’s case presented at the end of this work.

Kondenzační parní turbína / Condensing Steam Turbine

Šrůtek, Petr January 2016 (has links)
The theme of master's thesis is the design of condensing steam turbine with three unregulated steam outputs. The steam parameters in individual outputs are dealt with in heat balance circulation. This chapter is followed by thermodynamic and strength calculations, including the calculation of the turbine gland steam and design of drainage. Structural design of the turbine is also included in this thesis.

Využití termických panelů pro zvýšení účinnosti chladiciho okruhu TČ / Utilization of thermal panels to increase the efficiency of the heat pump cooling circuit

Lainka, Pavel January 2016 (has links)
This thesis evaluates the connection of solar collectors with heat pump. The work demonstrates meaningful use of solar collector to increase cooling efficiency of the heat pump. Introduction The work introduces the reader to the issue and describes basic principles of the two main sources of energy used in the system - the heat pump and solar system. Next session is dedicated to analysis and evaluation of the data that was measured during system operation. A comparison of measured COP of the heat pump at two different modes of operation was used for the evaluation - with the help of the solar system and without using the solar system.

Povrchové zpracování vybraných ocelí pomocí elektronového svazku / Surface treatment of selected steels using electron beam

Oríšek, Petr January 2016 (has links)
The thesis aims for the surface treatment of materials using electron beam. It includes a literary research describing physical principle and properties of the electron beam. This research also presents possible influencing of the beam and describes the construction of the device that generates the beam. Various applications of the electron beam for the material treatment are presented in the second part of the paper. Within this thesis an experiment with the heat treatment of the steel surface by the electron beam has been realized. The experiment was aimed at creating a layer as deep as possible without melting the surface. The results and their evaluation are presented in the experimental part of the thesis. The attention is also paid to selected process parameters.

Návrh vytápění a vzduchotechniky pro dvoupatrový rodinný dům po rekonstrukci / Design of heating and ventilation system for two-storey family house after renovation

Potočník, Jan January 2016 (has links)
The thesis is focused on the design of the reconstruction of a house built in the 70s of the last century. Part of this work is an introduction with the current state of the object and calculation of the appropriate heat losses. In the next step, renovations containing building insulation, replacement windows and doors, replacement of the heating system and the installation of air conditioning are made. Based on the design of the adjustments are again calculated heat losses and a comparation of energy savings is made. Another part of the proposal focuses in detail on heating system and its regulation. The final chapter deals with the design of the ventilation device using heat recovery. Attachments contain detailed calculations and necessary documentation.

Návrh vytápění nízkoenergetického rodinného domu / Heating system of a Low-energy house

Jankola, Mario January 2016 (has links)
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.
