    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

  3. 2. Refrigerant Selection for District Heating’s Large-scale Heat Pumps

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Görkem Balyaligil; [2023]
    Nyckelord :heat pump; district heating; refrigerant; natural; synthetic;

    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

  4. 3. Köldmedieläckage i kylanläggningar : En utredning om alternativa metoder för att detektera läckage

    Uppsats för yrkesexamina på grundnivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Christian Westerberg; Henric Gustavsson; [2021]
    Nyckelord :Kylteknik; kylanläggning; läckage; läckagedetektering; köldmedium;

    Sammanfattning : Commercial refrigerant industry is one of the biggest contributing factors toglobal warming according to a study by Mota-Babiloni et al. (2015). Studies have shown that emissions of fluorinated greenhouse gases' effect on global warming can increase from 1.3% (2004) to 7. LÄS MER

  5. 4. Fjärrvärmedriven Absorptionskyla : En ekonomisk undersökning av olika spetslösningar

    Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Bodil Strömqvist; [2021]
    Nyckelord :Absorption chiller; peak load solution; district cooling; district heating driven cooling; Absorptionskyla; spetslösning; fjärrkyla; fjärrvärmedriven kyla;

    Sammanfattning : This independent degree project has been implemented on behalf of FVB Sverige AB in collaboration Sundsvall Energi AB with the initial purpose of mapping manufacturers of hot water driven absorption chillers. After that, several technical solutions are examined to manage the peak load of a theoretical object which cannot produce the cooling power required with only an absorptions chiller, due to limitations in the district heating supply.

  7. 5. Utvärdering och jämförelse av CO2-kylsystem i en livsmedelsbutik

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Maria Lööf; [2019]
    Nyckelord :;

    Sammanfattning : Supermarket refrigeration systems are large emitters of high GWP refrigerants, and due to the Montreal protocol and F-gas regulation, which aim to phase out high GWP refrigerants, refrigeration systems with alternative refrigerants must be implemented in order to secure climate friendly and efficient refrigeration. One increasingly more popular alternative is transcritical refrigeration systems using only CO2 as a refrigerant. LÄS MER
