1. 16. ManagementPractical Aspects of Aqua Ammonia as Secondary Refrigerant in Ice Rinks

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

   Author : Jacqueline Pierri; [2021]
   Keywords : Ice rink; secondary refrigerant; refrigeration; refrigerant management; secondary fluid; natural refrigerant; aqua ammonia;

   Abstract : The transition from fluorinated gases to natural refrigerants could be key to reducing the impacts of climate change. Ice rinks are energy-intensive buildings, with large heating and cooling demands. The pumping power required to move the secondary refrigerant typically accounts for a sizable amount of the energy use of the refrigeration system. READ MORE

4. 18. Attenuation of fan noise with passive methods : An experimental study in the implementation of a ducted fan inside the body of a blended wing body UAV

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Mustafa Kulbay; [2021]
   Keywords : ;

   Abstract : This report is about a novel approach to attenuation of fan noise in aerial vehicles, by way of implementing a ducted fan in the chassis of a four meter blended wing body plane. Three different one meter PVC pipes were used and their performances as silencers were tested by measuring the sound power level and calculating the insulation loss compared to a fan by itself.
