    Sammanfattning : Combined cycle gas turbine power plants (CCGT), as part of the electricity generation fleet, are required to improve their flexibility to help balance the power system under new scenarios with high shares of variable renewable sources. Among the different possibilities to enhance the power plant performance, an inlet air conditioning unit offers the benefit of power augmentation and “minimum environmental load” reduction by controlling the gas turbine intake temperature using cold thermal energy storage and a heat pump.

  4. 3. Modeling and Optimization of Energy Utilization of Air Ventilation System of an Auditorium

    Master-uppsats, Högskolan i Gävle/Energisystem

    Författare :Kappina Kasturige Kamani Sylva; [2016]
    Nyckelord :Hybrid Ventilation; CFD modeling; Auditorium;

    Sammanfattning : Maintaining IAQ (Internal Air Quality) and thermal comfort of occupants in buildings have been a challenge to overcome satisfying the two ends: criteria for sustainability and cost effectiveness. Although there was a movement for mechanical ventilation systems in the recent past, in addition to the cost involved, they are found to not deliver the desired air quality, lead to social consequences such as sick building syndrome, contribute to environmental consequences related to ozone-depleting substances with increasing energy consumption, generate noise and having difficulties in cleaning and maintaining.

  5. 4. PERFORMANCE EVALUATION OF A SOLAR   COOLING SYSTEM IN UAE – RAS AL KHAIMAH BY BOTH EXPERIMENT AND SIMULATION

    Master-uppsats, Akademin för teknik och miljö

    Författare :Martin Ssembatya; [2013]
    Nyckelord :Solar driven cooling;

    Sammanfattning : In United Arab Emirates (UAE), a huge proportion of electrical energy consumed in buildings is used to run air conditioning equipments. This is because UAE’s climate is characterized by very high ambient temperatures and high humidity, especially during summer periods. LÄS MER

  7. 5. Komfortkylsystems installationskostnader och energiförbrukning i kontor

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för tillämpad fysik och elektronik

    Författare :Antonios Eriksson Stephanopoulos; [2011]
    Nyckelord :;

    Sammanfattning : På uppdrag av Creanova AB har detta examensarbete genomförts under hösten 2010. Målet med examensarbetet var att analysera hur installations- och energikostnaderna för komfortkylsystem i standardkontor varierar med olika dimensionerande förutsättningar. LÄS MER
