NATURAL CIRCULATION BY CONDENSATION

Natural circulation by condensation is a particular system that exploits the natural process of evaporation and condensation of a fluid to carry out the heat transfer. Thanks to this technology, the heat exchange occurs at maximum speeds, countering the triggering of inverse parasitic circulations, which constitute a critical element for all other thermal systems. In short, the condensation thermal system realizes within itself the same sequence that nature performs during the process known as the “water cycle”, which makes itself manifest to everyone with the phenomenon of rain.

  

WORKING PRINCIPLE

The fluid contained in the circuit evaporates thanks to solar radiation and reaches, in its gaseous state, the heat exchanger, where it releases its energy in the form of latent condensation heat. In the exchanger, therefore, the heat-carrying fluid condenses to return to its liquid phase and, by simple law of gravity, re-descends into the lower part of the collector where it will be reheated by the sun to start a new cycle again. At night, the heat transfer fluid returns into liquid form, occupying the lower part of the manifold thus preventing the inverse cycle from starting.
