1. 1. Status Mapping of tank to grave management of Low-GWP refrigerants.

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Sandra Parra Gimeno; [2023]
   Keywords : Refrigerant; Blends; Synthetic low-GWP refrigerant; Natural refrigerant; Global Warming Potential GWP ; Tank-to-grave; Interviews.; Köldmedier; Blandning; Globalt uppvärmningspotential GWP ; Låg-GWP köldmedier; Naturligt köldmedier; installation till destruktion; Intervjuer.;

   Abstract : 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. READ MORE

3. 2. Heat Export from Supermarkets : Refrigeration Systems Field Measurements and a Techno-economic Analysis

   University essay from KTH/Energiteknik

   Author : Julia Linnea Hildur Almebäck; Rebecka Magnius; [2022]
   Keywords : Heat Recovery; Heat Export; Supermarkets; Refrigeration Systems; CO2 Transcritical Booster Systems; Energy Efficiency; Värmeåtervinning; värmeexport; livsmedelsbutiker; kylsystem; CO2 transkritiskt boostersystem; energieffektivitet;

   Abstract : 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. READ MORE

4. 3. Optimizing Energy System in a Supermarket : A case study analysis

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Filip Josefsson; [2022]
   Keywords : R744; heat recovery; refrigeration system; supermarket; optimization; water-cooled condenser gas cooler; R744; värmeåtervinning; kylsystem; livsmedelsbutik; optimering; vattenkyld kondensor gaskylare;

   Abstract : With more restrictions regarding the use of refrigerants with high GWP-values, refrigeration systems that uses R744 (Carbon dioxide) as a refrigerant increases. Supermarkets are energy intense facilities where the refrigeration system utilize a significant part of the total utilized energy. READ MORE

5. 4. Review and Design Adaptations of a SrCl2-NH3 bench-scale Thermochemical Heat Storage system

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Hjörtur Brynjarsson; [2021]
   Keywords : Thermochemical heat storage TCS ; SrCl2-NH3; system design; kinetics; absorption; desorption; octaammine; diammine; monoammine; pressure management; commissioning; Termokemisk värmelagring TCS ; SrCl2-NH3; systemdesign; kinetik; absorption; desorption; oktaammin; diammin; monoammin; tryckhantering; driftsättning;

   Abstract : Thermochemical heat storage (TCS) is a thermal energy storage (TES) technology used to store thermal energy for later use. TCS can provide heating or cooling services from intermittently available thermal energy, often low grade waste heat. READ MORE

6. 5. CO2 Refrigeration withIntegrated Ejectors : Modelling and Field Data Analysis ofTwo Ice Rinks and Two Supermarket Systems

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : SIMON FEHLING; [2021]
   Keywords : Vapor Ejector; Liquid Ejector; Field Data Evaluation; Modelling; Refrigeration; CO2; Ice Rink; Supermarket; Heat Recovery; Ångejektor; Vätskeejektor; Fältmätdata; Modellering; Kylteknik; CO2; Isbana; Livsmedelsbutik; Värmeåtervinning;

   Abstract : With the increasing importance of CO2 as natural refrigerant with low Global Warming Potential(GWP) ejectors have been used in a number of recent installations to recover expansion work atthe high operating pressures of these systems. In colder climates, this is particularly seen in combinationwith heat recovery due to the high compressor discharge pressures. READ MORE
