    Sammanfattning : In this report the design and testing of a plug and play system to run Coolfinity’s Icevolt 300 refrigerator on solar panels is discussed. Such a system will be able to provide adequate cooling for food & beverages in area’s with unreliable or no electricity available. LÄS MER

  5. 4. 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

  7. 5. Optimization of a large scale solar installation through virtual storage : Profitability of using the refrigeration system in a grocery store as energy storage

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Erik Larsson; Jesper Sundin; [2019]
    Nyckelord :PV; solar power; virtual storage;

    Sammanfattning : In order to fulfil the goals set by EU and in the Swedish energy agreement an increased share of renewable electricity production, like wind and solar power, is necessary. Due to current legislations photovoltaic (PV) installations are usually limited to the 255 kWp energy taxation rule, or to fit the consumption profile of the building. LÄS MER
