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

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

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

   Sammanfattning : 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. LÄS MER

   Sammanfattning : Urban areas are responsible for a significant part of greenhouse gas emissions. Megacities, especially, have cumulative impacts due to different anthropogenic heat sources and urban heat island phenomena. It is therefore vital to replace fossil fuel burning heating sources with renewable sources in the current building stock. LÄS MER
