  1. 1. Geothermal function integration in ice rinks with CO2 refrigeration system

    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Juris Pomerancevs; [2019]
    Nyckelord :Ice rinks; CO2 refrigeration system; geothermal energy; heat recovery.; Ishallar; CO2 kylsystem; geoenergi; värmeåtervinning;

    Sammanfattning : Ice rinks are energy intense industrial applications. A typical single sheet ice rink in Sweden uses about 1000 MWh/season. A state-of-the art ice rink systems can use less than 500 MWh/season, indicating the potential for improvements. LÄS MER

  3. 2. Propane Heat Pump Modelling and Monitoring for System Control Analysis

    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Fernando Mengod Bautista; [2019]
    Nyckelord :;

    Sammanfattning : The objective of this master thesis was the performance analysis of a non-conventional heating system layout based on a propane heat pump unit. The objective had been pursued by monitoring and modelling the system. First, the project focused on monitoring the system, since for a correct modelling it was necessary to have all the data of the system. LÄS MER

  4. 3. Techno-economic analysis of combined heat pump and PV systems in Austria

    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Twan Schreurs; [2019]
    Nyckelord :;

    Sammanfattning : With the increasing amount of buildings that are being renovated in Austria, the potential of replacing conventional heating systems with heat pumps increases and thus CO2 emissions could be reduced. Several companies therefore focus on installing combined heat pump and PV systems. LÄS MER

  5. 4. Development of a configurable model for temperature distribution estimation in multifamily houses with limited amount of sensors

    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Federica Bozzi; [2019]
    Nyckelord :;

    Sammanfattning : The biggest environmental challenge of the current century is limiting the CO2 emissions in order to contrast the global warming and keep the temperature increase below 2.0K with respect to the pre-industrial age. For succeeding in this goal, significant changes are required in all sectors, including the energy one. LÄS MER

  7. 5. Capability Perception of an Electric Utilityduring Sectoral Change towards Sustainability

    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Christopher Politano; [2018]
    Nyckelord :;

    Sammanfattning : This thesis examines the antecedents of employees’ capability cognition within a medium-sized electricity utility (Ntot 􀵎 1200) in German-speaking Switzerland. The firm implemented a new strategy in 2015 with the aim to shift its core capabilities towards sustainability. LÄS MER
