SIMULATION OF THERMOSYPHON SYSTEMS FOR SOLAR DOMESTIC HOT WATER PRODUCTION

摘要

This contribution deals with the working principle ofrnthermosyphon systems in brief, describes the results of arnworldwide market analysis on thermosyphon solar waterrnheaters, gives a insight into modelling and simulation ofrnthermosyphon systems and concludes by presentingrnsimulation results for Gaborone (Botswana) comparedrnwith three European locations. In Gaborone it is possiblernto achieve 2,000 kWh·a-1 of hot water with a systemrnconsisting of a 1.9 m~2 solar collector and 180 l hot waterrnstorage.
