   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

4. 3. Control Design for an Energy-Sharing Module of Next-Generation Thermal Energy System ectogrid™

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Lisa Korsell; Tuva Ydén; [2021]
   Keywords : Technology and Engineering;

   Abstract : Today, heat and electricity production are two main sources of greenhouse gas emissions. A big share of the overall energy consumption is used to provide buildings with heating and cooling. Smart-energy solutions of heating and cooling could therefore be a more sustainable solution contributing to the green transition of the energy system. READ MORE

5. 4. Evaluation of decentralized ventilation system with heat recovery

   University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

   Author : Sunkavalli Kowshik Chowdary; [2020]
   Keywords : Decentralized ventilation; airflow; air draught; heat exchangers; tracer gas; Technology and Engineering;

   Abstract : Humans spend 90% of their times indoors, and maintaining a pleasant indoor environment is essential. Factors like human behaviour, combustion sources, cleaning supplies, affect the indoor environment, which could potentially affect the human health.the most common answer to controlling the indoor environment is a good HVAC system.
