Thermal system

THERMAL SYSTEM
The principle involves passing a fluid through a receiver (pannels or tubes) in order to recover the calories issued by the Sun. This fluid, that we are trying to heat, is in general water, either for industrial purpose (for example : pre-heat of water for a brewery) or for convenience (shower). This water can be heated in the panel itself and then stored, or going through panels in a closed-loop. The panels absords the calories produced by the sun and restore them in the holding tank through an exchanger tubular (Coil).
The water that circulates in the pannel is operated by a pump (Closed-loop systems are under pressure and self drainable) either by thermosyphons that do not require any power.
It's also possible to heat other fluid, as air, for a drying process for example. Instead of a pump, it's a ventilation system that creates the flow. In that case the used panels are different.
