  1. 1. Solar Photovoltaic Thermal Collectors and Ground Source Heat Pumps for Commercial Buildings : Case study in Sweden

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Doris Dijak; Elin Torstensson; [2023]
    Keywords : Ground Source Heat Pump; Photovoltaic Thermal Collectors; Borehole Thermal Energy Storage; Free Cooling.; Bergvärmepumpssystem; Termiska Solceller; Borrhålsbaserade Termiska Energilager; Frikyla.;

    Abstract : In order to reduce emissions from the building sector, which stands for than a fifth of the global energy consumption today, efficient and fossil free heating and cooling systems are of importance. This study investigates the combination of solar photovoltaic thermal collectors and ground source heat pump systems in order to regenerate energy to the ground in combination with free cooling.

  3. 2. Demand controlled ventilation : Impact on energy use and indoor environmental quality

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Therese Ottosson; [2023]
    Keywords : ;

    Abstract : European buildings account for a significant share of the energy-related emissions in Europe. Addressing the increasing energy use and its contribution to greenhouse gases (GHG) is internationally recognized as crucial, and emissions must be halted. READ MORE

  4. 3. Technical performance modelling and optimization of PVT collectors in GSHP integration

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Marin Courcault; [2023]
    Keywords : PVT; ISO9806:2017; mass flow; use conditions; test conditions; coefficients optimization; TRNSYS; PVT; ISO9806:2017; massflöde; användningsförhållanden; testförhållanden; optimering av koefficienter; TRNSYS;

    Abstract : In order to contribute to reducing the CO2 emissions related to heating in housing buildings, PVT+GSHP systems appear to be interesting solutions and therefore need to be further investigated to optimise their design and increase their deployment on the field. This thesis focused on building PVT model, using the ISO9806:2017, to be integrated in a PVT+GSHP model and determining optimal PVT design parameters for this system. READ MORE

  5. 4. Modelling and Techno-economic Analysis of a Hybrid CSP/PV System using Solid Oxide Electrolyser for Hydrogen Production

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Chuanyin Tang; [2023]
    Keywords : Power to Hydrogen; Solid Oxide Electrolyser; CSP; PV; LCOE; LCOH.;

    Abstract : This project proposes a solar-driven hybrid system for electricity generation and hydrogen production, which includes concentrated solar power (CSP), photovoltaic (PV), solid oxide electrolyser (SOEC). Electricity from the CSP and PV provides a continuous 24/7 supply to meet demand-side power consumption.

  6. 5. Solar cooling systems : A comparative analysis for solar thermal and solar PV cooling systems for Industries using a techno-economic approach

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Christoffer Larsson; [2022]
    Keywords : Photovoltaic cooling; solar thermal cooling; global LCOC;

    Abstract : With the need to reduce CO2 emissions in the energy sector, ensure electric grid stability and reduce future cost uncertainties for process cooling, solar cooling can be an interesting solution. This report describes the comparison of solar cooling with either a photovoltaics system or a solar thermal system using a thermally driven chiller. READ MORE
