The book has been released in July 2014 and provides answers to the following questions:

  • Which markets / what potential is there for solar thermal cooling?
  • Where and under which conditions do these systems operate economically?
  • What are the important design criteria?
  • What must be observed during installation and maintenance?
  • How do solar panels, thermal chillers, cooling distribution and storage work?
  • Which solar cooling systems already operate successfully around the globe?Buch Cover

The book includes the following chapters:

  • Solar thermal collectors
  • Solar cooling technologies
  • Cold distribution
  • Storage components
  • Designing and sizing
  • Installation, operation and maintenance
  • Economic feasibility
