1. 6. Resilient cooling technologies : Simulation study to determine the cooling capacity in old residentialbuildings located in mid-Sweden

   Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

   Författare :Ali Talib Ali; [2022]
   Nyckelord :cooling; cooling demand; absorption chiller; absorption refrigeration; district cooling; primary energy; resilience; residential buildings; old buildings; cooling capacity.;

   Sammanfattning : The Long-term changes in the climate conditions have increased the need foradequate thermal comfort systems. These alternations influence extremeevents, which their intensity and frequency have increased over the past years.Moreover, this study focuses on space cooling and parameters that the systemshould have to be considered as resilient.

   Sammanfattning : This study focuses on researching the performance of CO2 heat pumps in different real-time applications and in some studies, it compares the performance to synthetic and other natural refrigerants based on heat pump data provided from buildings. The research on the performance of the CO2 heat pump is performed based on Sweden's climatic conditions. LÄS MER

5. 9. 5th Generation District Heating and Cooling : A High-Level Simulation Model of a Novel District Energy Network

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Författare :Viktor Olofsson; [2022]
   Nyckelord :5GDHC; district heating; district cooling; district energy; energy systems; renewable energy;

   Sammanfattning : 5th generation district heating and cooling is a novel approach to district heating and cooling networks. Instead of a centralized energy supply, the technology relies on multiple building-level energy centers, equipped with heat pumps and chillers. LÄS MER

7. 10. Evaluation of overheating risks and passive cooling measures in low energy Swedish dwellings

   Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

   Författare :Sammar Kassab; Salma Aljabri; [2022]
   Nyckelord :Overheating; Passive cooling; Thermal comfort; Energy-efficient building; Building simulation; Heat wave; Residential dwellings; Occupant comfort and health; Measurement criteria.; Arts and Architecture;

   Sammanfattning : Overheating in buildings is becoming a major concern and cause for various health issues. Existing research and previous studies on the issue were examined to acquire relevant information about the definition of overheating, its possible causes, and the heath impacts it could have on human health.
