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. 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

4. 3. Study of passive design and slab cooling in adaptation to climate change of a modern residential building in Stockholm

   University essay from KTH/Hållbara byggnader

   Author : Sofia Elpasidou; [2020]
   Keywords : Climate change; future-ready buildings; passive design; slab cooling; thermal comfort; energy use; building performance; Klimatförändringen; framtidsfärdiga byggnader; passiv design; golvkyla; termisk komfort; energianvändning; byggnadsprestanda;

   Abstract : The impact on the built environment due to the forecasted climate change was presented by the authorities more than one decade ago, but the actions from the building industry to adapt buildings for a changed climate are still lacking. The purpose of this study is to identify a suitable cooling technique for a modern residential building in a future warmer climate in order to maintain thermal comfort but also energy efficiency.

5. 4. Geothermal function integration in ice rinks with CO2 refrigeration system

   University essay from KTH/Tillämpad termodynamik och kylteknik

   Author : Juris Pomerancevs; [2019]
   Keywords : Ice rinks; CO2 refrigeration system; geothermal energy; heat recovery.; Ishallar; CO2 kylsystem; geoenergi; värmeåtervinning;

   Abstract : Ice rinks are energy intense industrial applications. A typical single sheet ice rink in Sweden uses about 1000 MWh/season. A state-of-the art ice rink systems can use less than 500 MWh/season, indicating the potential for improvements. READ MORE

6. 5. Propane Heat Pump Modelling and Monitoring for System Control Analysis

   University essay from KTH/Tillämpad termodynamik och kylteknik

   Author : Fernando Mengod Bautista; [2019]
   Keywords : ;

   Abstract : The objective of this master thesis was the performance analysis of a non-conventional heating system layout based on a propane heat pump unit. The objective had been pursued by monitoring and modelling the system. First, the project focused on monitoring the system, since for a correct modelling it was necessary to have all the data of the system. READ MORE
