Heat transfer and sustainable energy technologies

Energy is the key issue for this century, while having limited resources there is still a growing demand, and this leads to a critical phase where controlling resource becomes strategic. Besides the sole energy aspect, global warming is now a reality, and several major natural catastrophes these last years made the public more aware and conscious that the human activity has an impact on our climate. Therefore the scientific and engineering communities have to develop advanced energy technologies, which will meet the need of all the sectors: industry, transport and building. Three main options have to be considered (1) improve existing energy technologies and reduce their environmental impact, (2) develop innovative technologies for better energy management and promote energy efficiency and (3) develop advanced energy technologies such as renewable energies and new energy carriers. The Heat-SET (Heat Transfer in Components and Systems for Sustainable Energy Technologies) conference series has been launched. It provides a platform for researchers from industry and academia to exchange information and identify research needs in the area of heat transfer in components and systems for sustainable energy technologies. The first conference (Grenoble, France, 5–7 April 2005), has attracted 165 participants from 35 countries. The main topics of the conference were • • • •

Heat recovery, boilers and furnaces; Air-conditioning and refrigeration; Heat exchangers; Solar heating and cooling;

• • • • • •

Energy storage and distribution; Building and district heating; Heat pumps; Heat transfer; Fuel cells; Energy systems.

For this special issue of Applied Thermal Engineering, 13 manuscripts have been selected by the scientific committee, representing the various topics of the conference and giving emphasize to engineering aspects and practical developments. The first four papers deal with heat recovery systems, and describe heat exchanger, fouling and absorption machine. The next six papers are devoted to compact and micro-channel heat exchangers. The last three papers present advanced building air-conditioning technologies. We would like to invite the readers to attend and contribute to the next issue of the Heat-SET conference (Heat Transfer in Components and Systems for Sustainable Energy Technologies), that will take place in Chambery, France from 18 to 20 April 2007 (www.greth.fr/heatset).
