1. Status Mapping of tank to grave management of Low-GWP refrigerants.
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Refrigeration plays a vital role today in various residential, commercial, and industrial processes, requiring refrigerants to facilitate the cooling or heating processes. Over time, refrigerants have undergone significant changes to meet technological, social, environmental, and economic needs. LÄS MER
2. Comparative Analysis of Modern Energy Systems for Ice Rinks
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Ice rinks are highly energy-intensive commercial buildings with an average annual energy consumption of 1,000 MWh, most of it being used to cover the simultaneous heating and cooling demands. The aim of this thesis is to find the most energy efficient energy system for ice rinks by evaluating different system modifications and refrigerants. LÄS MER
3. Investigation of new refrigerants for a large-scale heat pump and evaluation of system performance
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : Heat production accounted in 2021 for 50 % of the energy end use globally, where a strongconnection to fossil sources still exists. Large-scale electrical heat pumps can therefore have akey role in the energy system to enable a decreased reliance on fossil fuels and at the same timecontribute to stable system when incorporating more intermittent renewable sources.

4. Refrigerant Selection for District Heating’s Large-scale Heat Pumps
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The global demand for heat as the primary source of final energy underscores the urgency of decarbonizing the heating sector to foster sustainability. Heat pumps are crucial in achieving sustainability, particularly in district heating applications, offering efficient centralized heating solutions. LÄS MER
5. Design of high performance buildings : Vulnerability of buildings to climate change from an energy perspective
Master-uppsats, KTH/Hållbara byggnaderSammanfattning : The challenge of climate change is twofold: to mitigate (prevent) the causes of climate change and to prepare (adapt) to the inevitable effects and consequences. Building and construction are key sectors for decarbonisation (mitigation). LÄS MER
