Title: Aggregate mass air circulation and structural support system for generally enclosed structures.
Inventor: BERGERON HERVIN J JR
IPC: F24F3/00
Filed: 1980-07-02
Abstract: An improved heat transfer and air circulation system for homes and like constructions. A mass of relatively non-heat conductive aggregate supports the slab (16) or floor of the home. Air is circulated by a blower (20) from the interior of the home into and through the aggregate mass (40) positioned between the slab (16) and the underlying supportive earth, and thence back into the interior of the home. Heat transfer occurs between the supportive earth and the air flowing through the aggregate mass (40) and between the air flowing through the aggregate mass (40) and the slab (16). Thus, the slab (16) itself becomes a heat transfer surface.
