1. 21. 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

5. 24. Techno-Economic Analysis of Small-Scale Polygeneration Systems for a Ground Based Air Defence Operations Center in the Swedish Armed Forces

   University essay from KTH/Kraft- och värmeteknologi

   Author : Alma Klipic; Sidar Eken; [2020]
   Keywords : Polygeneration; STandUP;

   Abstract : Climate change is an important topic of today's discussion where scientists have determined that a large proportion of the increasing global temperatures is a product of the increasing greenhouse gases in the atmosphere. Globally it is expected that the share of renewable power generation is set to increase with 50 % between 2019 and 2024. READ MORE

6. 25. Conditioned atria in the built environment - A possible solution for unsustainable urbanization and climate change in Nordic climates?

   University essay from Mittuniversitetet/Institutionen för ekoteknik- och hållbart byggande

   Author : Lucas Cupello de Vasconcellos; [2020]
   Keywords : Conditioned atrium; built environment; final energy consumption; energy efficiency; indoor gardens; green spaces; Internationella Engelska Skolan Östersund; International English School Östersund; temperate climates; Nordic climates; weather damage; refurbishment; repair; impact; environmental impact;

   Abstract : The aim of the research is to explore the differences in final energy consumption and environmental impact of the construction materials related to the atrium alternative and a business-as-usual and evaluate how to improve thermal properties of old buildings that require renovations to fit thermal efficiency standards and comfort in operational conditions while reducing the overall impact of the projects. Results show that for the low-rise atrium most of the parameters related to the final energy demands and environmental impacts of the atrium construction materials are proportional and linear to the increase of the glazing area size.
