  • Patent number: 4766951
    Abstract: A linear panel unit for use on walls or ceilings capable of providing radiant heating and/or cooling. The panels have an external panel shell, which itself can be used as a passive panel, an extruded aluminum radiator panel resting in the shell with outward side in contact with the shell and an inward side in contact with a copper tube capable of containing fluids of varying temperature. Clips between bilateral troughs in the sidewall of the panel shell and the inward side of the radiator panel secure contact between rediator panel and the shell. The copper tube is grasped by projecting channel walls in the inward side of the radiator panel which also are tapered to facilitate positioning of the clips and a groove near the intersection with the radiator panel to secure placement of the clip. A panel unit wall or ceiling is created by interspersing radiant linear panels with identically appearing passive panel shells, the copper tubes of the active radiant panel units communicating with one another.

  • Patent number: 4735257
    Abstract: The invention relates to an arrangement in an interior panel (2) or the like having a rearwardly located space through which air which has been heated is arranged to flow, to eliminate the radiation of cold from a wall, a floor or the like. In accordance with the invention, the space is confined and divided into at least two thin air cavities (4,5), by means of an intermediate plate (3) which extends parallel to the interior panel (2) and which comprises a material having good heat-insulating properties. The heated air is arranged to be circulated in the air cavities, around the intermediate plate. A heater is provided for heating the air passing to the air cavity (4) adjoining the interior panel, to a temperature of at most some few degrees above the room temperature. A fan (10) is controlled by an air flow control regulator (10') which is actuated by a thermostat (14) which compares the temperature of the air as it moves out of the inner space (4) with the intended room temperature.

  • Patent number: 4476921
    Abstract: Low grade heat is supplied to heat air which is used to provide an insulating sheath for a building or the like. The low grade heat is obtained from the ground below the hard frost line from either air or water, or from solar collectors, biomass or any other suitable source of such heat, and is used to heat air which is then circulated in a space within the walls of the building, thereby maintaining the internal temperature within the walls at approximately 45.degree.-65.degree. F. The air insulating sheath so provided reduces the driving force which takes heat out of the building in winter and which permits heat entry in summer. The energy required to bring the internal building temperature to a comfortable degree in winter or summer is thereby drastically reduced, as is the cost associated therewith.

  • Patent number: 4440343
    Abstract: 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.
