  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

  3. 17. Design and Modelling of a Container for Optimal Flow Rate and Wastewater Purification

    University essay from Umeå universitet/Institutionen för fysik

    Author : Olle Stenlund; [2021]
    Keywords : CFD Simulation; Design; Construction; Pumping System; Water purification;

    Abstract :   Industries are becoming more aware of how they use water in their production process. In many cases, they release wastewater back into the water supply untreated, which can cause adverse side effects to the ecosystem. A sustainable environment requires efficient water purification. One approach to purify wastewater uses rotating bed reactors. READ MORE

  4. 18. Internal strain in the magnetocaloric alloy MnCoSi

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Olivia Vaerst; [2021]
    Keywords : MnCoSi; Magnetocaloric Effect; Arc Melting; Strain; X-Ray Diffraction; Williamson-Hall; Rietveld Refinement; Physics and Astronomy;

    Abstract : Cooling systems based on magnetic refrigeration are a promising and environmentally friendly alternative to commonly used gas-compression refrigeration. Magnetic refrigeration is based on the magnetocaloric effect. READ MORE

  5. 19. Energieffektivisering av dricksvattendistribution : dataanalys och simulering av pumpdrift vid Görvälns vattenverk

    University essay from SLU/Dept. of Energy and Technology

    Author : Anton Thorstensson; [2020]
    Keywords : norrvatten; förbrukningsprognos; renvattenpumpar; högreservoarer; vattentorn; fyllnadskrav;

    Abstract : This project investigates the efficiency of the water distribution system from Görväln's pumping station to Norrvatten's central consumption zone. The goal is to propose actions that lead to enhanced energy efficiency. READ MORE

  6. 20. The carbon footprint caused by the oversizing of building service systems : A case study of an NHS Hospital

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Maria Hein; [2020]
    Keywords : Design; dimensioning; heating; cooling; boiler; chiller; pump; energy performance; environmental impact; mitigation strategy;

    Abstract : Energy usage in buildings is a main contributor to CO2 emissions and in order for the EU to reach the 2050 goal of carbon-neutrality, there is a great need to improve the energy efficiency in buildings, particularly commercial buildings that often are substantially overdesigned. Excess margins in the design process of building services result in an oversizing of these systems which has great environmental impacts, divided up as the operational and embodied carbon footprints.
