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 Cooling – Towards Improved Substation Performance
Sammanfattning : The global cooling demand in buildings is rapidly increasing and to supply this demand, district cooling is one solution. However, many district cooling systems suffer from low delta-Ts (receiving low return temperatures from the buildings connected to the system). LÄS MER
3. Gothenburg District Cooling System - An evaluation of the system performance based on operational data
Sammanfattning : The global energy demand for providing cooling in buildings is expected to increase the next decades, along with a rapid growth in the number of air conditioners and chillers. A more energy efficient, economical and environmentally viable solution to this increased cooling demand, is district cooling. LÄS MER
4. The role of absorption cooling for reaching sustainable energy systems
Sammanfattning : The energy consumption is continuous to increase around the world and with that follows the demand for sustainable solutions for future energy systems. With growing energy consumption from fossil based fuels the threat of global warming through release of CO2 to the atmosphere increases. LÄS MER
5. 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
