Thermosyphon Solar Energy Water Heaters

  • Chapter

Abstract

A review of research, development and system appraisal activities concerned with natural-circulation solar-energy water-heaters is presented. The history of their use and the factors which have influenced their popularity are discussed. An overview of the present commercial situation is provided and the advanced product engineering of recent designs highlighted. Mathematical models which describe the thermal behaviours and the experimentally-observed operational characteristics of thermosyphon solar water heaters are examined. Alternative means of preventing nocturnal reverse circulations are discussed. Results are reported of studies comparing thermosyphon unit performances with those of other solar-energy water-heaters. Comparative evaluations are also reported for the behaviours of direct and indirect thermosyphon systems. Current approaches to standard test procedures for rating whole systems are described.
