1. Heat driven cooling in district energy systems
Sammanfattning : Abstract The threat of global warming, caused by increasingemissions of carbon dioxide (CO2), is one reason why cooling supply systems mustwork more efficiently in the world today. An increasing share,currently between 10 and 20%, of the global output ofelectricity is consumed to produce cooling. LÄS MER
2. District Heating and CHP : Local Possibilities for Global Climate Change Mitigation
Sammanfattning : Global warming, in combination with increasing energy demand and higher energy prices, makes it necessary to change the energy use. To secure the energy supply and to develop sustainable societies, construction of energy-efficient systems is at the same time most vital. LÄS MER
3. Transition pathways for future district heating and cooling systems with thermal energy storage
Sammanfattning : Buildings’ heating and cooling account for more than 20% of the final energy use within the European countries and are dominated by non-renewable resources. Future district energy systems should enable efficient, fossil-free, and economical energy supply at operating temperatures that end users can directly utilize. LÄS MER
4. Utilization of a GSHP System in a DHC Network : modeling and optimization
Sammanfattning : The ground source heat pumps (GSHPs) of customers connected to the district heating and cooling (DHC) network can benefit both the customer and the energy company. However, operating the GSHP to minimize the cost of providing heating and cooling to the customer while ensuring the long-term stability of the ground temperature is a challenge. LÄS MER
5. Assessing District-Heating Sustainability – Case Studies of CO2 Mitigation Strategies and Environmental Cost Accounting
Sammanfattning : District heating (DH) may play an important role in achieving the EU goal of a secure, competitive and sustainable energy supply. Integrated energy solutions based on technologies, such as biomass gasification for transport fuel, electricity and heat production and heat-driven absorption cooling, create new optimisation possibilities through the linkage between heat, power, cooling and transport fuel markets which may reduce the global warming contribution of the energy sector.
