Klimatizace líhně kuřat / Air Conditioning of chicken brooder

Petr, Lukáš January 2009 (has links)
My diploma thesis focuses on design of air-conditioning system for chicken breeding spaces. In the background are considered general issues of air-conditioning, hatchery layout and microclimate for eggs incubation and chicken breeding. The research part is divided into two parts – Calculations and Design. The Calculations address the amount of incoming fresh air, heat loss, heat load and psychrometric calculations for summer and winter periods. The Design focuses on defining suitable diffusers and air-ducts, optimal air-conditioning unit with fans corresponding to hatchery requirements and pressure loss in ducts. The technical drawings and a list of used material are included.

Klimatizační systém jednoho reprezentativního podlaží budovy A1 / Air-conditioning system of a typical floor of A1 building

Pekárek, Antonín January 2009 (has links)
Master thesis deals with designing of air-conditioning system into newly reconstructed high-rise building of Faculty of Mechanical Engineering Brno University of Technology. Reconstruction of a building results in change of thermo-technical parameters which impacts dimensioning of air condition system. Designing air-conditioning system depends on heat loss and heat gain calculation and also on consequential psychometrical calculations. The size of air conditioning equipment which provides required internal microclimate will be determined from the calculation results. Currently there is Detail design elaborated including technical report and material specification.

VÄtrac­ a chladic­ syst©m bytu v panelov©m domÄ / Design of air conditioning system of a flat

Vrbick, Ji­ January 2011 (has links)
The diploma thesis is consisting of theoretic part, which deal with used ventilating systems, ways of waste heat recovery and describe basic types of air-conditioning systems. Following part attend to design of ventilating system and multi-split air-conditioning system for flat. Part of design of ventilation system is calculation of noise levels in rooms. Air-conditioner design is based on calculation of thermal stress. Annual demand of cold and heat demand are calculated using TRANSYS software. Design documentation is part of the diploma thesis.

Klimatizace lékárny / Air-conditioning of pharmacy

Martincová, Lenka January 2013 (has links)
Diploma thesis is focused on air-conditioning and hot air ventilation of the pharmacy. The pharmacy is a part of a supermarket building. The pharmacy has its own engine room and air-conditioning. Solution is focused with the calculation of the flow rate, thermal losses and profit of pharmacy. Power of heater, cooler and humidifier are calculated according to psychrometric evaluation. Distribution elements and distribution of a duct are designed according to the flow rate of air. Total pressure losses in the duct are calculated according to the distribution in the conclusion. Units are designed for hot air ventilation and air conditioning and the engine room. In appendix there are calculations of thermal losses and gain, output from programme of CLIMACAL, drawing documentation and material specifications.

Návrh vzduchotechniky a vytápění pro výrobní podnik / HVAC in a production plant

Černík, Václav January 2013 (has links)
This master’s thesis deals with heating and HVAC in production plant ELMET, spol. s r.o. The first part of the thesis concerns reconstruction of the central heating system, which is outdated and unreliable in the time of the writing of the thesis. The second part deals with cooling of mounting of electronics, where technological requirements are not met due to summer overheating. The third part of the thesis concerns ventilation of metalworking hall using waste heat from production machines.

Návrh výroby držáku klimatizace / Production of air conditioning holder

Šproch, Daniel January 2013 (has links)
The holder of outdoor air-conditioning units are made out of steel 11 321.21 with 2mm thickness. The production quantity is 2000 units / year. The holder is produced using CNC machine for cutting and bending on CNC press brake. The semi-finished product is a metal sheet (2 x 2000 x 1000 mm). Part of this diploma thesis is to design of the population with the punching tools, the layout of parts on the metal sheet and design of appropriate press brake punches and dies. The conclusion contains economic evaluation of the proposed solution.

Vytápění a chlazení RD s kombinovaným systémem dodávky tepelné a el. energie / Heating and cooling for residences with complex energy supply system

Pavlíček, Michal January 2015 (has links)
Heating and cooling along with the indoor air quality is now discussed topic not only in the family houses. Goes hand in hand with reducing the energy consumption of buildings. This fact is edited by various laws or Regulations, no matter we discuss new buildings requirements, or for example energy label on older constructions.

Návrh lisovacích přípravků na manifoldové sestavy kondenzátoru automobilové klimatizace / Design of pressing machines for manifold assembly of condensers in car air-conditioning unit

Juriga, Jakub January 2016 (has links)
The diploma thesis deals with the design of pressing machines for manifold assembly of condensers in the car air-conditioning unit. The problem of the current assembling process is its inefficiency. Semi-automated assembly using pneumatic pressing machines eliminates this problem. In the theoretical part the air-conditioning components, current state of assembly and calculating base of pressing are described. In the practical part the test of pressing force was conducted. Based on this test, the design of four pneumatic pressing machines was accomplished. In the final part of the work, evaluation of the whole project is provided.

Energeticky úsporný administrativní objekt s posilovnou a wellness Kostka / Energy efficient office building with gym and wellness Kostka

Kotas, Marek Unknown Date (has links)
The master thesis describes a complete design of an office building, including its technical equipment. The building's technical equipment contains HVAC, lighting, DHW and photovoltaics design, water demand. The building has two floors. It contains offices, a bistro with a lounge, a wellness area and two gyms, a children's playground and facilities. This master thesis is divided into three parts. Firstly, the thesis presents building documentation with an engineering and an accompanying report. Secondly, the thesis introduces the design of the building's technical equipment and engineering reports. Lastly, the results of a conducted experiment are presented. In this experiment, a system for the optimization of blind tilt angle is proposed.
