1. 21. Preliminary analysis of the potential energy saving achievable with a predictive control strategy of a heat pump for a single family house

   Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

   Författare :Giacomo Braida; Roberto Tomasetig; [2018]
   Nyckelord :heat pump system control; HVAC predictive rule-based control; weather forecast; occupancy behavior; internal gain; ambient temperature; perfect prediction;

   Sammanfattning : The present work reports a study related to the potential improvement of the energy performances of a heat pump based heating system for a Swedish single-family house. The analysis is focused on the design of new rule-based control strategies which employ perfect predictions of weather forecast and human behaviour information. LÄS MER

3. 22. Concentrating Collector for Torsång District Heating System

   Master-uppsats, Högskolan Dalarna/Energiteknik

   Författare :Artem Filatov; [2018]
   Nyckelord :Concentrating solar collector; Absolicon; Arcon; Heatstore; flat-plate collector; Borlange; Torsang; Sweden; parabolic trough; thermal collector;

   Sammanfattning : In this thesis report for Dalarna University in Borlange and Absolicon company the study of a possibility to add an array of concentrating solar collectors to a Torsång district heating system was done. The whole idea of this work was to make a simulation of this kind of system, trying to get 15-20% of solar fraction, and make an economical evaluation. LÄS MER

4. 23. Simulation of an energy efficient single-family house in the area of Smedjebacken to meet Miljöbyggnad’s Gold House energy category requirements

   Master-uppsats, Högskolan Dalarna/Energiteknik

   Författare :Parham Daroudi; [2018]
   Nyckelord :TRNSYS; insulation thickness; ground source heat pump; district heating; heat recovery ventilation; Miljöbyggnad;

   Sammanfattning : Since the building construction area is accounted for high share of energy usage (36 %) in Europe, there is high demand to pay attention to this area accurately. Sweden which is one of the pioneer countries in terms of building energy efficiency plans to reduce this value to 50 % by 2050. LÄS MER

5. 24. Comparison of solar thermal and photovoltaic assisted heat pumps for multi-family houses in Sweden

   Master-uppsats, KTH/Energiteknik

   Författare :Martin Andersson; [2018]
   Nyckelord :Solar Thermal; PV; Heat Pump; KPI; Multi-family houses; TRNSYS;

   Sammanfattning : The building sector account for 40 % of the global energy demand, and an increasingly popular way to supply buildings with heat is through the use of heat pumps. Solar thermal (ST) can either be used as a low temperature energy source in the heat pump or to directly supply the building’s heating demand. LÄS MER

7. 25. Weather data for heat pump system control improvement: analysis of instantaneous and forecasted measurements and evaluation of potential energy savings

   Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

   Författare :Mattia Monteggia; [2018]
   Nyckelord :heat pump system control; HVAC predictive rule-based control; weather forecast; occupancy behavior; internal gain; ambient temperature; perfect prediction;

   Sammanfattning : The present work deals with a study related to the analysis of weather data for heat pump system control improvement based on both instantaneous and forecasted measurements. In particular, the analysis is firstly focused on the comparison of multiple weather sources for the assessment of weather forecast uncertainties, based on the evaluation of errors in prediction with respect to measured values.
