Patent number: 4602676Abstract: The system is composed in essence of an aggregate mass through which air can be blown, film sheeting enveloping the mass, and apparatus for directing a flow of air from the interior of a home or other building structure through the aggregate mass and back into the interior. The slab or floor of the home rests on and is supported in part by the enveloped mass. The aggregate mass is a relatively poor conductor of heat and thus heat transfer occurs mainly between the air flowing through the mass and the slab or floor above the mass and the ground below the mass. Apparatus for recovering waste heat within the home is described. Desirably, the system is used in conjunction with a solar collector. The system with or without the solar collector reduces substantially the energy required to heat and cool the home.Type: GrantFiled: March 3, 1981Date of Patent: July 29, 1986Assignees: Stephen J. Ledet, Jr., James Donald ElderInventor: Hervin J. Bergeron, Jr.

Patent number: 4541479Abstract: The system is composed of an aggregate mass through which air can be blown, film sheeting enveloping the mass, and apparatus for directing a flow of air from the interior of a home or other building structure through the aggregate mass and back into the interior. The slab or floor of the home rests on and is supported in part by the enveloped mass. The aggregate mass is a relatively poor conductor of heat and thus heat transfer occurs mainly between the air flowing through the mass and the slab or floor above the mass, and between the air flowing through the mass and the ground below the mass. Preferably, the air from the interior of the building structure is blown into the aggregate mass at an interior location thereof, collected around the perimeter of the enveloped aggregate mass and transferred to the interior of the building structure at peripheral locations in its interior space above but in proximity to the slab or floor. Apparatus for recovering waste heat within the home is also described.Type: GrantFiled: August 13, 1984Date of Patent: September 17, 1985Assignees: Stephen J. Ledet, Jr., James D.

Patent number: 4538507Abstract: A network of adjacent aggregate containing mesh bags provides structural support to the slab or floor of a building. The network, encased in a sheath of plastic film, also functions as a path for air to be directed by a blower. The openings within the network are filled with gravel, sand or earth packs. At the perimeter of the network an air return system leads to the interior of the building. Thus, the blower can circulate air from the building interior through the network and air return system and back into the interior. Air circulating in the network can undergo heat exchange through the plastic film at the interfaces of the slab, the packs, and the underlying ground. Peripheral ground insulation minimizes lateral heat transfer. Preferably the aggregate containing mesh bags have indexing means to indicate their respective heights from above as they rest on a supportive planar surface.Type: GrantFiled: September 8, 1983Date of Patent: September 3, 1985Assignees: Stephen J. Ledet, Jr., James D. ElderInventor: Hervin J. Bergeron, Jr.

Patent number: 4505325Abstract: An improved heat transfer and air circulation system for homes and like constructions wherein heat is removed from the home or like construction and stored for later utilization. The system utilizes a blower with a non-conductive aggregate structural circulation medium supporting the home and transmits circulating air from the home to the area adjacent the underlying soil mass thereby providing an effective and workable heat transfer thermal cap system for use under the floor or slab portion of a home to be heated or cooled.Type: GrantFiled: July 3, 1979Date of Patent: March 19, 1985Assignees: Stephen J. Ledet, Jr., James Donald ElderInventor: Hervin J. Bergeron, Jr.
