Demonstration kit Solar thermal energy conversion


For demonstrating the fundamentals and technical applications of solar thermal energy conversion.
This kit contains apparatus for basic experiments on heat absorption, convection and radiation, as well as allowing the assembly of a complete solar collector with thermal siphon recirculation, pump circulation and heat exchanger.
 
The solar collector ...

  • converts energy radiated by the sun into heat using water to convey the energy.
    After shining the light on the collector for several minutes, it is possible to measure a distinct rise in temperature.
  • is used in conjunction with the included reflector projector, which acts as the source of energy.
  • has two removable front panes of glass to prevent convection losses.
  • has a blackened collector spiral with six loops and two connectors for rapid release hose couplings.
  • has interchangeable black and white painted rear  covers, expanded polystyrene insulation and a removable plexiglass pane at the rear.

 
Heat exchanger with pump circulation
With the help of the heat exchanger it is possible to transfer thermal energy from one liquid to another. It consists of a copper tubing coil in a transparent plastic beaker with quick-release hose couplings.
The conveyance of the water through the exchanger coil is aided by connecting a circulating pump to the collector.
 
Thermosyphon circulation
If the elevated tank is connected via the supplied hoses to the solar collector, there will arise a difference in density of the water dependent on the temperature which will cause convection to occur, thus circulating the water.
