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. Heat Export from Supermarkets : Refrigeration Systems Field Measurements and a Techno-economic Analysis
Master-uppsats, KTH/EnergiteknikSammanfattning : Supermarkets have a high energy demand where almost half of the energy is used within the refrigeration system. The refrigeration system utilises a cycle where heat is taken and rejected. The rejected heat could be recovered and utilised for other purposes, such as covering internal heating demand or be exported to other facilities. LÄS MER
3. Optimizing Control Algorithm for Indirect Liquid ThermalManagement of Batteries : A Study Executed at Northvolt
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The vast expansion of intermittent sustainable energy generation has favoured a gradual adoption of lithium-ion batteries in various industrial and automotive applications. Despite its many inherent merits, this storage technology is very vulnerable to temperature variations: the performance and lifespan of LIBs are substantially influenced by their load cycles, thermal behaviours, and operating temperature range.

4. Internal strain in the magnetocaloric alloy MnCoSi
Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenSammanfattning : Cooling systems based on magnetic refrigeration are a promising and environmentally friendly alternative to commonly used gas-compression refrigeration. Magnetic refrigeration is based on the magnetocaloric effect. LÄS MER
5. Kartläggning av kylkompressorer : Baserad på katalogdata från kompressortillverkare
Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Rapporten ämnar kartlägga beteendet för de vanligaste typerna av kylkompressorer, vid användning av köldmedier med låg GWP (global warming potential) under olika driftsförhållanden, samt att tillgängliggöra denna kartläggning i form av diagram och tabeller. Av de parametrar som utgör kartläggningen, så ligger huvudfokus på den isentropiska och volymetriska verkningsgraden. LÄS MER
