In cooperate with Asko Cylinda we have developed a new heat system too short the process time and reduce the energy consume in a dishwasher and still have it too be a class AAA. The environment and quality is important for the company too still be the number one on the market, If they want too keep that position the product developed of new innovations will be very important. The systems we have developed are more effective and reduce energy up too 25 %. The process time is reduced too less than two hours, from the today two and half-hour. The solutions are too heat up the rinse water and the dishwater at the same time, with a new heating system and it make are solutions unique and effective. Its good for the dish and the environment. This will help the company too still be the number one on the market for household appliances.

Ultrafast Structural and Electron Dynamics in Soft Matter Exposed to Intense X-ray Pulses

Jönsson, Olof January 2017 (has links)
Investigations of soft matter using ultrashort high intensity pulses have been made possible through the advent of X-ray free-electrons lasers. The last decade has seen the development of a new type of protein crystallography where femtosecond dynamics can be studied, and single particle imaging with atomic resolution is on the horizon. The pulses are so intense that any sample quickly turns into a plasma. This thesis studies the ultrafast transition from soft matter to warm dense matter, and the implications for structural determination of proteins.                    We use non-thermal plasma simulations to predict ultrafast structural and electron dynamics. Changes in atomic form factors due to the electronic state, and displacement as a function of temperature, are used to predict Bragg signal intensity in protein nanocrystals. The damage processes started by the pulse will gate the diffracted signal within the pulse duration, suggesting that long pulses are useful to study protein structure. This illustrates diffraction-before-destruction in crystallography. The effect from a varying temporal photon distribution within a pulse is also investigated. A well-defined initial front determines the quality of the diffracted signal. At lower intensities, the temporal shape of the X-ray pulse will affect the overall signal strength; at high intensities the signal level will be strongly dependent on the resolution. Water is routinely used to deliver biological samples into the X-ray beam. Structural dynamics in water exposed to intense X-rays were investigated with simulations and experiments. Using pulses of different duration, we found that non-thermal heating will affect the water structure on a time scale longer than 25 fs but shorter than 75 fs. Modeling suggests that a loss of long-range coordination of the solvation shells accounts for the observed decrease in scattering signal. The feasibility of using X-ray emission from plasma as an indicator for hits in serial diffraction experiments is studied. Specific line emission from sulfur at high X-ray energies is suitable for distinguishing spectral features from proteins, compared to emission from delivery liquids. We find that plasma emission continues long after the femtosecond pulse has ended, suggesting that spectrum-during-destruction could reveal information complementary to diffraction.

Teplonosné látky tepelných soustav / Of heat transfer fluid of heat systems

Ženožička, Filip January 2018 (has links)
The subject of this diploma thesis is the design of heating and hot water in the administrative building in Zlin on Jižní Svahy. The building has five floors above ground and one underground floor. There are designed two variants of heat source for heating and hot water (transfer sta-tions and gas boiler). Part A solves water quality in heating systems. Part B deals with design of the heating system, hot water heating, insurance and facility expansion, technical report and drawings heating in the building. The last part C is the experimental measurement of the quality of heating water in the CZT systems.

Hasičská zbrojnice a tělocvična / Fire station with gym

Svoboda, Martin Unknown Date (has links)
The aim of the work is to design Fire station with a gym in Olomouc. Diploma thesis has three parts. First from institute of building structures, second from intitute of building services and last part is devoted to modeling and assessment of details of building. Fire station is divided into three parts. Garage for 3 fire trucks, main part and gym with training tower. The main part contains toilets, showers, locker rooms, storage places, offices and facilities for firefighters and office rooms. Structural elements of the building are from reinforced concrete. Infill walls are made from ceramic bloks. Thermal insulation is from mineral wool and cladding of the wall is made of fibre-cement boards. The slab in the main part is made of cast-in-place concrete. Others slabs in the garage and gym are made of prefabricated elements. On the building are desined three types of roofs. Extensive green roof, flat roof with a stabilization layer of river aggregates and roof made of insulating sandwich panels. In the thesis is design conception of artificial lighting, ventilating, heating, cooling, water managment, photovoltaics and management scheme of energy and ecological systems. The work contains project documentation for building permits, which were made in accordance with applicable legal and technical regulations.

Kvalita otopné vody pro zdroje tepla / Hot water quality for heat

Snášelová, Tereza January 2017 (has links)
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.
