  1. 1. Direct-Ground Cooling Systems for Office Buildings: Design and Control Considerations

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Taha Arghand; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Borehole; Cooling capacity; Laboratory experiments; Ground heat exchanger; Fluid temperature levels; Control; Direct-ground cooling; Optimization; High temperature cooling;

    Abstract : Direct-ground cooling systems are defined as systems in which the ground is used as the only source for cooling mainly in commercial buildings. These systems benefit from exchanging heat with the ground, of which its temperature is basically constant below a certain depth year around. READ MORE

  2. 2. Modeling and Performance of Gas Turbine Cycles with Various Means of Blade Cooling

    University dissertation from Department of Heat and Power Engineering, Lund university

    Author : Kristin Jordal; Lund University.; Lunds universitet.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid dynamics; Gases; termodynamik; Termisk teknik; applied thermodynamics; Thermal engineering; blade cost; HAT cycle; humid air; model validation; blade cooling modeling; thermodynamic simulations; blade cooling; Gas turbine; plasmas; Gaser; fluiddynamik; plasma; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Abstract : A method for simulating the cooled gas turbine is demonstrated. Based on equations and other knowledge found in the literature, a first-law thermodynamic, non-dimensional model is established and implemented in the equation-solving, programmable software IPSEpro. READ MORE

  3. 3. Cooling Strategies for Wave Power Conversion Systems

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Antoine Baudoin; Uppsala universitet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave power; power conversion system; thermal management; power elctronics; passive cooling; natural convection.;

    Abstract : The Division for Electricity of Uppsala University is developing a wave power concept. The energy of the ocean waves is harvested with wave energy converters, consisting of one buoy and one linear generator. The units are connected in a submerged substation. The mechanical design is kept as simple as possible to ensure reliability. READ MORE

  4. 4. Combined Electricity Production and Thermally Driven Cooling from Municipal Solid Waste

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Seksan Udomsri; KTH.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; municipal solid waste; incineration; hybrid cycle; power production; thermally driven cooling; absorption chillers; decentralized thermally driven cooling; district heating; TECHNOLOGY Engineering mechanics Mechanical and thermal engineering; TEKNIKVETENSKAP Teknisk mekanik Mekanisk och termisk energiteknik; SRA - Energy; SRA - Energi;

    Abstract : Increasingly intensive efforts are being made to enhance energy systems via augmented introduction of renewable energy along with improved energy efficiency. Resource constraints and sustained high fossil fuel prices have created a new phenomenon in the world market. READ MORE

  5. 5. Cooling demand in commercial buildings-The influence of building design

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Hendrik Voll; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solar factor; influence of design; cooling load; Commercial buildings; energy need; window share;

    Abstract : Large window areas and glass façades have become popular by architects. As the glass architecture has become fashionable in quite a short time it seems that the architects are not always aware of the energy consuming consequences that the highly glazed buildings, sometimes in combination with special room plans might cause.
