1. 6. Increasing the value of household appliances by adding a heat pump system

   Författare :Peder Bengtsson; Jonas Berghel; Tomas Persson; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heat pump; Appliances; ASKO; Energy system; Energiteknik; Energy Technology;

   Sammanfattning : Historically, domestic tasks such as preparing food and washing and drying clothes and dishes were done by hand. In a modern home many of these chores are taken care of by machines such as washing machines, dishwashers and tumble dryers. LÄS MER

3. 7. Capacity-controlled Ground Source Heat Pump Systems for Swedish single-family dwellings

   Författare :Hatef Madani; Per Lundqvist; Joachim Claesson; Jose Miguel Corberan Salvador; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heat Pump; Capacity control; ground; ground source; geothermal;

   Sammanfattning : The overall objective of this thesis is to develop a structured method to approach the challenge of better understanding the techniques and potential for capacity control in Ground Source Heat Pump (GSHP) systems used in Swedish single-family dwellings. This thesis aims at development of a generic model of the system that can be used for comparative, descriptive, and predictive analysis of capacity controlled GSHP systems in single-family dwellings.

4. 8. Smart control of PV and exhaust air heat pump systems in single-family buildings

   Författare :Emmanouil Psimopoulos; Joakim Widén; Chris Bales; Tomas Persson; Jarek Kurnitski; Uppsala University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photovoltaics; heat pump; forecast services; thermal storage; electrical storage; control algorithms; TESHP Test av solvärmepumpsystem; TESHP Test av solvärmepumpsystem;

   Sammanfattning : Recently, decentralized household photovoltaic (PV) systems have become more affordable and there is a tendency to decrease subsidies for the PV excess electricity fed into the grid. Therefore, there is growing interest in methods to increase the self-consumption (SC), which is the part of the electricity produced by PV and directly consumed on buildings. LÄS MER

5. 9. Modelling the dynamics of domestic low-temperature heat pump heating systems for improved performance and thermal comfort : a systems approach

   Författare :Dimitra Sakellari; Per Lundqvist; Savvas Tassou; KTH; []
   Nyckelord :Technology; heat pump; domestic heating and ventilation; low-temperature hydronic heat distribution; systems approach; integration; simulation; energy efficiency; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : The present environmental concerns and the rising human requirement for solutions with better comfort and lower costs have resulted in an increased awareness for the energy use in the built environment. Technical advances in building structural systems and materials, heating and other comfort-providing systems and controlling strategies all lead to the integration of building technology with the function of buildings and the aesthetics.

7. 10. Smart Energy Grids – Utilization of Space Heating Flexibility

   Författare :Johan Kensby; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; demand side management; heat pump; thermal energy storage; exhaust air heat pump; thermal storage in buildings; heat price control; smart; District heating; heat source shifting; demand response;

   Sammanfattning : Buildings are the largest energy-using sector in the world. Since the generation of energy is highly associated with greenhouse gas emissions, contributing to climate change, there is a large focus on reducing energy use in buildings. LÄS MER
