  2. 1. Solar heat pump systems for heating applications : Analysis of system performance and possible solutions for improving system performance

    Author : Stefano Poppi; Per Lundqvist; Chris Bales; Kai Siren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar heat pump systems; techno-economics; solar thermal; system improvements; cost-effectiveness; Energiteknik; Energy Technology; MacSheep;

    Abstract : Solar heat pump systems (SHPs) are systems that combine solar energy and heat pumps. SHPs have been investigated for several decades and have been proven to increase the share of renewable energy and reduce electric energy demand in residential heating applications. READ MORE

  4. 2. Increasing the value of household appliances by adding a heat pump system

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

    Abstract : 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. READ MORE

  5. 3. Capacity Control of Residential Heat Pump Heating Systems

    Author : Fredrik Karlsson; RISE; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy efficiency; variable-speed; air-source; performance; hydronic heating system; ground-source; heat pump; defrost; optimisation; circulator; capacity control;

    Abstract : Heat pumps used for space and sanitary hot water heating of residential buildings are increasingly popular in northern Europe. As they compete with other heating equipment and in order to limit the environmental impact of their use, it is very important that heat pumps are energy efficient. READ MORE

  6. 4. Evaluation of Modular Thermally Driven Heat Pump Systems

    Author : Corey Blackman; Eva Thorin; Chris Bales; Christian Schweigler; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sorption heat pump; sorption module; thermochemical energy storage; artificial neural network; built environment; solar energy; gas-driven heat pump; solar cooling; heating and cooling; renewable energy; energy efficiency; experimental; simulation; analytical; Energy- and Environmental Engineering; energi- och miljöteknik; Reesbe företagsforskarskola;

    Abstract : The building sector accounts for approximately 40% of primary energy use within the European Union, therefore reductions in the energy use intensity of this sector are critical in decreasing total energy usage. Given that the majority of energy used within the built environment is for space conditioning and domestic hot water preparation, prudence would suggest that decreasing primary energy used for these end purposes would have the biggest overall environmental impact.
