Passive solar collector module for building facades (EPO)

Abstract

The invention relates to a passive solar collector module for building facades comprising a transparent panel and a heat absorbing panel, separated from one another by an air chamber and assembled in a frame; an upper air conduit for communicating the air chamber with an area close to the ceiling of a story of a building; a lower air conduit for communicating the air chamber with an area close to the floor of a story of a building; an environmental air inlet in the lower part of the module and a heated air outlet and in the upper part of the module; a first air directing system operable such that in a first position it blocks the air outlet and in a second position it blocks the upper air conduit; a second air directing system operable such that in a first position it blocks the lower air conduit, in a second position it blocks the air flow towards the air outlet and in a third position it does not block either the lower air conduit or the air flow towards the air outlet.
