  1. 1. Development of a Simulation Model for Combined PVT and Ground Source Heat Pump Systems : A TRNSYS Model Created for Commercial Use

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

    Keywords : Electrify everything; Solar assisted heat pump; Solar Energy; TRNSYS; Elektrifiera allt; solassisterad värmepump; Solenergi; TRNSYS;

    Abstract : The Swedish government has set a target of a 100% renewable electricity system by 2040. To reach this goal, many actions have to be undertaken. Electrification of buildings is one action to be undertaken as the residential sector accounts for a large share of greenhouse gas emissions, where the most energy efficient method is to use heat pumps.

  2. 2. Improving the Efficiency of Thermal Energy Usage in Residential Buildings by Heat Recovery from Wastewater

    University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet; Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Author : Pranjal Jain; Khaled Alturkmani; [2021]
    Keywords : Wastewater; Heat Exchangers; Heat Pumps; Biofilms;

    Abstract : This study aims to rationalize the consumption of thermal energy in residential buildings by recovering heat from wastewater inside the building before entering the central sewage network outside the building, by conducting an analytical study for a residential tower in Syria to find out the coverage percentage of the heat energy recovered from wastewater for the heating and domestic hot water loads needed for the tower, and calculating the percentage of reduction in carbon dioxide (CO2) gases. It is a simple technology as the thermal recovery system consists of three main components, which are in order: a wastewater tank, heat exchangers, and a heat pump. READ MORE

  3. 3. Model Predictive Climate Control for Electric Vehicles

    University essay from Uppsala universitet/Avdelningen för systemteknik; Uppsala universitet/Avdelningen för systemteknik

    Author : Erik Norstedt; Olof Bräne; [2021]
    Keywords : MPC; model predictive control; climate control; electric vehicle; battery; thermal management; electrified vehicle; battery electric vehicle; nonlinear MPC; custom cost functions; elfordon; temperaturreglering;

    Abstract : This thesis explores the possibility of using an optimal control scheme called Model Predictive Control (MPC), to control climatization systems for electric vehicles. Some components of electric vehicles, for example the batteries and power electronics, are sensitive to temperature and for this reason it is important that their temperature is well regulated.

  4. 4. Technoeconomical evaluation of small-scale CO2 liquefaction using Aspen Plus

    University essay from KTH/Kemiteknik

    Author : Maja-Stina Svanberg Frisinger; [2021]
    Keywords : Carbon capture and storage CCS ; carbon dioxide; carbon neutral; production costs; pulp and paper mills; Avskiljning och lagring av koldioxid CCS ; koldioxid; koldioxidneutral; produktionskostnader; massa och pappersbruk;

    Abstract : Syftet med den här studien är att göra en teknoekonomisk utvärdering av processer för förvätskning av CO2 med hjälp av Aspen Plus. Ett flertal förvätskningsprocesser från tidigare studier jämfördes och från dessa valdes två förvätskningsprocesser ut för fortsatta studier och simuleringar. READ MORE

  5. 5. High Resolution Mapping and Spatial Analysis of Carbon Free Heat Sources for District Heating : A Case Study of Helsinki

    University essay from KTH/Energiteknik

    Author : Filip Norrman; Mattias Persson; [2021]
    Keywords : High-­Resolution Mapping; Carbon-­Free Heat Sources; 4th Generation District Heating; GIS; Hög­upplöst kartläggning; Koldoixidfria värmekällor; 4e generationen Fjärrvärme; GIS;

    Abstract : Heat production together with electricity production stands for 31% of the global CO2 emissions. The production is as of today still highly dependent on fossil fuels, with a global district energy mix share of fossil fuels of 90%. READ MORE
