  1. 1. Advances in Ventilation Heat Recovery : An assessment of peak loads shaving using renewables

    Författare :Behrouz Nourozi; Sasan Sadrizadeh; Adnan Ploskic; Carey Simonson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Peak heat load shaving; renewable energy; ventilation heat recovery; frosting in heat exchangers; Heat transfer; förnybar energi; ventilation värmeåtervinning; frosting i värmeväxlare; värmeöverföring; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : The building sector accounts for approximately 40% of total global energy usage.In residential buildings located in cold climate countries, 30-60% of this energy isused for space heating, 20–30% is lost by discarded residential wastewater, and therest is devoted to ventilation heat loss.

  3. 2. High-Capacity Cool Thermal Energy Storage for Peak Shaving - a Solution for Energy Challenges in the 21st century

    Författare :Bo He; KTH; []
    Nyckelord :Comfort cooling; peak shaving; phase change materials PCM ; cool thermal energy storage; DSC; phase change temperature; the heat of fusion; phase equilibrium; phase diagram.;

    Sammanfattning : Due to climatic change, increasing thermal loads inbuildings and rising living standards, comfort cooling inbuildings is becoming increasingly important and the demand forcomfort cooling is expanding very quickly around the world. Theincreased cooling demand results in a peak in electrical powerdemand during the hottest summer hours. LÄS MER

  4. 3. Design of Thermal Energy Storage with Phase Change Materials - Investigations within Material, Device and System Scale

    Författare :Pepe Tan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; T-History; Phase Change Materials; Thermal Energy Storage; Experimentation;

    Sammanfattning : The addition of a thermal energy storage (TES) into a process allows the operator to store and release thermal energy on demand. This increased process flexibility leads to potential benefits such as shifting energy demand from peak to off-peak hours. LÄS MER

  5. 4. Self-Regulating Active Chilled Beams

    Författare :Peter J Filipsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Comfort cooling; High temperature cooling; Self-regulation; Active chilled beams;

    Sammanfattning : By designing comfort cooling systems to operate with higher chilled water temperatures, electricity driven chillers may be replaced by natural sources of free cooling. It also enables the possibility of self-regulation which, due to simplicity and robustness, brings cost-savings both during installation and maintenance of the building. LÄS MER

  7. 5. Integration of Battery and Hydrogen Storage with a Grid-Connected Photovoltaic System in Buildings

    Författare :Yang Zhang; Jinyue Yan; Jianzhong Wu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photovoltaic; Grid; Building; Battery; Hydrogen Storage; Operation Strategy; Optimization; Energiteknik; Energy Technology;

    Sammanfattning :     The integration of Photovoltaic (PV) with buildings changes the previous electricity consumers into prosumers. The reduced PV subsidies and the grid stable operation requirements are pushing prosumers from direct exportation to self-consumption of the produced electricity. LÄS MER
