  1. 1. 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

  3. 2. Free cooling and PVT integration in a ground-source heat pump (GSHP) system

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

    Author : Christopher Pourier; [2023]
    Keywords : Ground-source heat pump; borehole; GSHP; photovoltaic thermal collector; PVT; free cooling; Ytjordvärmepump; borrhål; GSHP; solfångare; PVT; frikylning;

    Abstract : The performance of ground-source heat pump (GSHP) systems can be negatively affected over time by soil temperature degradation of boreholes (BH) in heating dominated climates. Land area is scarce in the dense urban environments typical of multi-family houses (MFH) and can lead to accelerated degradation- in tight BH fields. READ MORE

  4. 3. Experimental Testing of Solar Photovoltaic/Thermal Collectors for Low Temperature Heat Pump Integration

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

    Author : Jaakko Eskola; [2023]
    Keywords : Solar photovoltaic thermal; PVT; heat pump; thermal performance; ISO 9806:2017; Solhybrid; PVT; värmepump; termisk prestanda; ISO 9806:2017;

    Abstract : A hybrid photovoltaic/thermal (PVT) collector enables simultaneous electricity and heat production from a single solar module. Integrating PVT collectors with a ground source heat pump (GSHP) improves the seasonal performance of the heating system and prevents from temperature degradation of the ground. READ MORE

  5. 4. Data-driven modelsfor estimating heatpump powerconsumption

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

    Author : Monika Peskova; [2023]
    Keywords : heat pump; data-driven model; modelling; regression model; värmepump; data modell; modellering; regressionsmodell;

    Abstract : The number of installed heat pumps has been rapidly increasing in recent years, acceleratingthe decarbonisation of the heating sector. The impact of the increasing deployment of heatpumps on the grid can be evaluated with the help of models estimating the heat pumppower consumption. READ MORE

  6. 5. Energy Renovation: A case study of a multi-family house built during the Million program in Djursholm

    University essay from KTH/Energiteknik

    Author : Adiltogtokh Bold; [2022]
    Keywords : Energy Renovation; Refurbishment; Energy Efficiency Measure; Direct-electric Heating; Multi-family House; Energirenovering; Renovering; Energieffektiviseringsåtgärd; Direktverkande El; Flerfamiljhus;

    Abstract : Large share of Swedish building stock were built during 1940-1980 when people were not fully aware of the energy efficiency concept. Majority of the buildings that made energy declaration are in energy class E-G, which are considered as high energy consumption buildings with low energy performance, and only few buildings meet the Swedish requirements for near zero energy buildings which are in energy class A-C.
