Streszczenie:

The efficiency of air-breathing gas turbine engines improves as the combustion temperature increases. Therefore, modern gas turbines operate at temperatures greater than the melting temperature of hot-gas-path components, and cooling must be introduced in order to maintain mechanical integrity of those components. Two highly effective techniques used in modern designs for this purpose are impingement cooling and use of coolant film on hot-gas-path surface introduced through discrete film or effusion holes. In this study, these two mechanisms are coupled into a single prototype cooling system.

Streszczenie:

Individual heat/energy measurements have been a hot topic in Europe during the last 50 years, both for fair reasons and for energy saving reasons. The argument for using individual heat/energy measurements for fair reasons is that no one should pay more than he or she consumes no matter if the person lives in a rental apartment or in a house. Previous studies have shown that individual heat/energy measurements will lower the total energy consumed, when each tenant of a multi-apartment building has to pay for the actual amount of the consumed heat/energy individually.

The integrated solar roof collector system can bring the house year-round energy saving benefit. In heating season, part of the space heating and preheating domestic hot water demand can be met by this integrated system. In the cooling season, cooling load reduction and preheating domestic hot water can be achieved by operating this system. The traditional solar thermal system is an add-on system rather than integrated, which increases the cost-benefit ratio. The current system is integrated with the roof structure. Except for the energy collecting benefit, it will reduce the material cost, la

Cooling techniques for high density electrical components and electronic devices have been studied heavily in recent years. The advancements in the electrical/electronic industry have required methods of high heat flux removal. Many of the current electrical components and electronic devices produce a range of heat fluxes from 20 W/cm2 – 100 W/cm2. While parallel flow cooling systems have been used in the past, jet impingement is now more desirable for its potential to have a heat transfer coefficient 3-5 times greater than that of parallel flow at the same flow rate.

Water heating in a typical home in the U.S. accounts for a significant portion (between 14% and 25%) of the total home's annual energy consumption. The objective of considerably reducing the home's energy consumption from the utilities calls for the use of onsite renewable energy systems. Integral Collector Storage (ICS) solar domestic water heating systems are an alternative to help meet the hot water energy demands in a household.

The European Union has an ongoing commitment to reducing CO2 emission as highlighted by its agreement at the Kyoto Summit. One approach to achieving these reductions would be to develop alternative energy sources for major energy demanding sectors. In the EU, about 40% of all energy consumed is associated with buildings and of this, about 60% is utilised in the housing sector. A major part of the energy demand of buildings could be met by utilising renewable energy sources, e.g. solar energy.

In 2007, in June the company Europrojekt entered the project with the requirement of the formulation and implementation of heating motherly school by heat pumps in the village Hluk. The projekt was ordered by the management of this motherly school. This is a total reconstruction of the heating system building motherly school, including the use of residual heat for heating the pool water in an open swimming pool, which is located near this motherly school. The requirement is also given to reduce environmental pollution and achieve energy savings. This diploma thesis solves the detailed descript

The aim of this thesis is to elaborate project documentation for new construction of low-energy residential building with 16 luxury apartments, apartment without barriers and with pharmacy of basic type. It is a four-storey detached building without basement, with flat roof, roof terraces and with balconies. Residential building is located in one of the most enjoyable parts of the city of Zlín – Jižní Svahy II in the vicinity of Central park with bicycle path and with beautiful view of the Zlín. The building will be located on land plot No. 2144/46, where is still situated unfinished building

The district heating load is seasonally dependent, with a low load during periods of high ambient temperature. Thermal energy storage (TES) has the potential to shift heating loads from winter to summer, thus reducing cost and environmental impact of District Heat production. In this study, a concept of high temperature borehole thermal energy storage (HT-BTES) together with a pellet heating plant for temperature boost, is presented and evaluated by its technical limitations, its ability to supply heat, its function within the district heating system, as well as its environmental impact and ec

Les révolutions de l’Est ont induit la fragmentation des Etats qui s’est accompagnée, sur le plan interne par une renaissance des partis ethniques ; ce qui ne va pas sans poser de problèmes à la démocratie politique. Les transitions et a fortiori les consolidations démocratiques font émerger un double phénomène d’interaction entre les acteurs et le système, dans la recherche d’un nouvel équilibre. Les partis ethniques se politisent alors que le système s’ouvre à l’acteur ethnique. On assiste donc à un réajustement évolutif du système devant la nouvelle donne. Le système s’ouvre aux nouvelles d

abstract: Nanoparticle suspensions, popularly termed “nanofluids,” have been extensively investigated for their thermal and radiative properties. Such work has generated great controversy, although it is arguably accepted today that the presence of nanoparticles rarely leads to useful enhancements in either thermal conductivity or convective heat transfer. On the other hand, there are still examples of unanticipated enhancements to some properties, such as the reported specific heat of molten salt-based nanofluids and the critical heat flux. Another largely overlooked example is the apparent e

One of the most widely used solar collectors for process heating and large scale electricity generation is the parabolic trough collector (PTC), in which a tube placed at the focus of the parabola receives concentrated solar radiation. In this work, a novel solar receiver design is proposed that bridges the gap in efficiency between the evacuated and non-evacuated receivers which are presently in use. In the standard or commercial non-evacuated receivers, the absorbing surface loses the heat to the surrounding ambient and to the heat transfer fluid (useful heat). A novel receiver has been pro

This study centered on a novel thermoelectric generator (TEG) integrated into the built environment. Designed by Watts Thermoelectric LLC, the TEG is essentially a novel assembly of thermoelectric modules whose required temperature differential is supplied by hot and cold streams of water flowing through the TEG. Per its recommended operating conditions, the TEG nominally generates 83 Watts of electrical power. In its default configuration in the built environment, solar-thermal energy serves as the TEG’s hot stream source and geothermal energy serves as its cold stream source. Two systems-lev
