Cool Cell operating-modes schematic

Conceptual sketch of the Cool Cell’s seasonal operating modes:

• Summer day (top right): sun drives roof temperature too high for circulation; the ceiling tank absorbs interior heat instead.
• Summer night (bottom left): the roof radiates to the sky; thermosiphon recharges the tank with coolth.
• Winter (bottom right): sun drives circulation through the roof collector into storage.
