1. 1. An Evaluation Study of Leak Testing Technologies for Watertight Plate Heat Exchangers : Fast and sustainable leak testing technology for high energy efficiency products

   University essay from Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

   Author : Fritjof Nilsson; Yanjun Peng; [2023]
   Keywords : Leak rate; Optimization; Pressure Decay; Vacuum Technology; Volume; Läckhastighet; Optimering; Tryckfall; Vakuum Teknologi; Volym;

   Abstract : Background: One part of manufacturing a Plate Heat Exchanger (PHE) is to leak test them before delivery. Today, helium is used extensively in leak testing. How-ever, it is unsustainable to use helium in leak testing, because of its non-renewability and therefore becoming more and more expensive. Also, this technology is relatively complex. READ MORE

3. 2. 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

4. 3. 2D or not 2D: Assessing environmental awareness and cognitive load in mixed reality data visualizations : Visualizing gas leak data visualizations for an industrial surveying setting

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Julia Schwuchow; [2023]
   Keywords : environmental awareness; cognitive load; information visualization; mixed reality; sustainable HCI; miljomedvetenhet; kognitiv belastning; informationsvisualisering; mixad ¨ verklighet; hallbar MDI;

   Abstract : Increasing the environmental awareness of invisible data, such as a city’s air pollution or a household’s energy consumption, has been an ongoing information visualization challenge that has entered the fields of immersive technologies like augmented (AR) and mixed reality (MR). In order to understand how form and dimensional affect this understanding for MR environments, this research investigated what the difference between statistical, iconographic 2D and physical 3D visualizations is with regards to minimizing cognitive load and fostering environmental awareness.

5. 4. New process for leak detection in truck pneumatic systems during production using an ultrasound camera

   University essay from Uppsala universitet/Industriell teknik

   Author : Henrik Gustafsson; Malva von Schenck; [2023]
   Keywords : industry; leak detection; leak positioning; pneumatic system; pressure drop test; production; quality assurance; ultrasound camera;

   Abstract : The process of producing compressed air in the industry today is highly energy inefficient. Up to 75 % of the energy spent on producing compressed air to the compressed air systems (CASs) is wasted. Out of the produced air, 24 % is wasted due to air leaks. READ MORE

6. 5. Accelerated Testing of the End-plate Assembly of a Redox Flow Battery

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

   Author : Saksham Jindal; [2022]
   Keywords : Energy Storage; Flow Batteries; Accelerated Testing; Contact Resistance; Endplate Assembly; Leak Rate; Stack Design; Energilagring; flödesbatterier; accelererad provning; kontaktmotstånd; montering av ändplattor; läckagehastighet; utformning av staplar.;

   Abstract : As the world transitions to intermittent renewable energy sources like solar and wind, the need for long-duration energy storage technologies is becoming more and more prominent. In this regard, flow batteries are seen as a promising solution, owing to their inherent advantages like decoupling of power and energy, extremely high cycle life and negligible self-discharge.
