    Import 02/11/2016Tématem diplomové práce je využití odpadního tepla spalin pro ohřev teplé užitkové vody. Dnes je odpadní teplo víceméně vypuštěno do ovzduší, aniž by se nějak využívalo. Přitom v sobě obsahuje velký energetický potenciál. Diplomová práce vznikala ve spolupráci se společností VÍTKOVICE MECHANIKA a.s., která provozuje řadu energetických zařízení. Využívání této energie jako druhotného energetického zdroje, které vzniká v závodě při výrobních procesech, vede ke snižování provozních nákladů a k efektivnosti samotné výroby. Výsledkem diplomové práce by měl být návrh výměníku tepla, který bude sloužit k ohřevu teplé užitkové vody, která bude následně ve společnosti zužitkována, například pro sprchování apod.The thesis deals with the use of waste heat for domestic hot water. Today, more or less waste heat released into the atmosphere without using it somehow. Yet it incorporates a large energy potential. The diploma thesis was created in cooperation with VÍTKOVICE MECHANICS Inc., which operates numerous power plants. Use of energy as a secondary energy source, which arises in plant production processes, leading to a reduction in operating costs and the efficiency of production itself. The result of the thesis proposal should be heat exchanger, which will be used for domestic hot water, which will then be re-utilized in the company, such as showering, etc.635 - Katedra tepelné technikyvýborn

    Optimizing the total energy consumption and CO<sub>2</sub> emissions by distributing computational workload among worldwide dispersed data centers

    Get PDF
    Major internet service providers have built and are currently building the world's largest data centres (DCs), which has already resulted in significant global energy consumption. Energy saving measures, from chip to building level, have been introduced gradually in recent decades. However, there is further potential for savings by assessing the performance of different DCs on a wider scale and evaluating information technology (IT) workload distribution strategies among these DCs. This paper proposes a methodology to optimize the electricity consumption and CO2 emissions by distributing IT workload across multiple imaginary DCs. The DCs are modelled and controlled in a virtual test environment based on a building energy simulation (BES) tool (TRNSYS). A controller tool (Matlab) is used to support testing and tuning of the optimization algorithm. A case study, consisting of the distribution of IT workload across four different types of data centers in multiple locations with different climate conditions, is presented. The case study will illustrate.</p

    This paper introduces an innovative concept for active wall-curtain façade modules aiming at high level of energy autonomy. The façade module consists of two opaque panels and one transparent panel integrating building integrated photovoltaics supported by façade integrated battery Peltier air-conditioning unit, active shading, and LED lighting. The developed demo-protype was deployed at testing facility and subjected to long-term experimental monitoring to assess the energy performance in real environment. The complex monitoring system captured key power and thermal fluxes, temperatures, mass flows and other operational states of the active wall-curtain façade modules. These measurements were assessed in form of monthly overview depicting total electricity consumption, on-site energy production, heating and cooling delivery as well as self-sufficiency and self-consumption indicators

    The world data center energy consumption has been growing rapidly and currently is estimated at 1,7–2,2% of the world-wide electricity consumption. Achieving sustainability in this sector calls for development new energy efficient strategies and measures. Current research deals with development of holistic operation i.e. operation, where all essential processes such as data processing, cooling and power delivery and supply (including renewable energy sources) are optimized a coordinated. Testing of modern operational strategies, which is necessary for development and commissioning, is not possible during the regular operation due to the risk of limitation of the services or outage of the data center operation. Any outage of the data center is related with financial and reputation losses. Therefore, the testing is extremely limited. Alternatively, building energy simulation may offer “safe” testing environment for advanced control algorithms and accelerate their implementation in practice. This paper describes a novel workflow for testing of modern control algorithm and new application of building energy simulation of data center
