Absorption Machines for Heating and Cooling in Future Energy Systems

This project, which was concluded in June 1999, aimed to analyse the reasons behind the still limited implementation of absorption technology in heating and cooling. Participants in this project contributed by gathering relevant national information and by participating in two workshops. Its objectives were to gain a better understanding of market opportunities for absorption machines (machines using either absorption or adsorption technology), improve understanding of the technology, and disseminate information.


The objectives of the project were:

  • To study the present industrial and non-industrial applications of absorption technology for heating and cooling
  • To list and evaluate ongoing national research programmes concerning absorption technology
  • To identify new systems and new cycles utilised since 1990 (Annex 14)
  • To identify technical, economical, environmental and political obstacles for introducing absorption technology
  • To find ways to overcome the obstacles
  • To clarify environmental and political issues that strengthen or weaken absorption technology in relation to competing technologies.
