| Keywords: Thermosiphon solar water heating system.JPG The diagram displays a naivety of solar system design is unrealistic compared to practical systems and should not be used for educational purposes The solar panel is mounted at ground level with the storage tank raised in the building above to support a thermosyphon effect Although thermosyphon effect is obviously useful it is hard to make practical use of it in a solar system Some small systems manage this by using small external tanks above the panel which brings its own problems of insulation in a cold climate In a building though the effect of shading on a low-mounted panel far outweighs the thermosyphon benefit - practical panels are mounted as high up as possible so as to have better sun exposure The circulation system in the panel circulates the entire heat storage tank capacity Real systems use separate systems with a heat exchanger The systems is drawn with stratified heat storage in the tank i e separate hot and cold layers Stratification is an important aspect of design for an efficient system but it can only happen with non-circulating storage and use of heat exchangers The use of 5 Additional heater in the solar panel circuit is a bizarre fabrication If such a heater was provided it would either be an electric immersion heater inside the storage tank or else a separate primary circuit and heat exchanger for a heat source such as a wood stove The cited source diagram represents a gas or solid fuel boiler not a solar panel Thermosyphon is usual for such systems but it's not extrapolatable to domestic house solar systems It's WP OR to present it as such and in this case unworkable WP OR Andy Dingley <span class signature-talk >talk</span> 10 19 22 September 2010 UTC en Schematic of a thermosiphon solar water heating system A thermosiphon solar water heating system uses no pumps and is therefore more durable and less costly in operation no use of electricity The system presented here uses a mechanical cold water refill system The schematic was based on an image by SEI http //www seai ie/Schools/Secondary_Schools/Subjects/Physics/Unit_6_-_Heat_Transfer/Convection/ Own KVDP 2009-09-08 Thermosiphon solar water heating systems Solar heating schemas and diagrams | ||||
