Claims. (Cl. 257-124) This application is a division of our copending application, Serial No. 690,230, filed August 13, 1946 now Patent No. 2,800,308 granted July 23, 1957. The instant invention relates to a. wall or ceiling treatment and more particularly to a treatment adapted to serve as a source of radiant heat. Radiant heating is a recognized form of heating readily distinguishable from the more customary types involving convection and conduction, such as conventional hot air, water or steam systems. In the latter the air is initially heated and, by convection, heats the walls and objects within a room while in the former a surface such as the room wall is initially heated, the heat leaving the surface in the form of radiant energy which impinges upon, and is absorbed by, objects and persons within the room.

In prior proposals for radiant heating, a room Wall, often the ceiling, has been raised to the required temperature to serve as a source of radiant heat by embedding hot Water or steam lines in the plaster or in the concrete making up the ceiling slab. Such systems operate satisfactorily where the radiant surface is exposed, but are inefficient if the surface is covered as in the case where conventional acoustical treatments are employed.

The instant invention has for its particular object the provision of a ceiling or Wall treatment which will combine both the radiant heating and acoustical functions. One type of acoustical treatment which 'has achieved outstanding commercial success is that disclosed in patent to Norris, No. 1,726,500, issued August 27, 1929, consisting of a perforated facing behind which is disposed a sound-absorbing medium. The facing preferably takes the form of a plurality of individual metal pans containing pads of sound-absorbing material and having edges or flanges engaged in runners suspended from the base wall .or ceiling. The outer faces of the pans lie in substantially the same plane and form the visual ceiling of the room to which the'treatment is applied. Another object of the invention is the provision of a construction incorporating a radiant heat-ing system in an acoustical treatment of this type.

A further object of the invention is the provision of a system involving the conduction of heat to the faces of the metal pans, the latter forming the radiant surface. A still further object is the provision of a construction in which the heating medium, namely steam, hot water or the like, is conveyed through suitable conduits which support the pans, whereby heat will pass by conduction directly to the pans.

Our invention will be more fully understood and further objects and advantages will become apparent when reference is made to the following detailed description of a preferred embodiment and to the accompanying drawings in which:

Fig. l is a side elevational view illustrating the construction of the invention;

Fig. 2 is a sectional view, taken at right angles to the conduits, of the construction of Fig. 1; and

2,845,252 Patented July 29, 1958 Fig. 3 is a diagrammatic plan view of one arrangement of the heating system.

Referring to the drawings, there are disclosed conduits 60, which are of the same type as those of the embodiments described in the said copendiug application, the conduits being similarly connected into supply and return lines. These conduits 60 themselves form the runners or supports for the perforated pans of the acoustical system. For this purpose the conduits may be first mounted in the ceiling at the proper intervals and supported by hangers 62. The pans, indicated at 64 in Figs. 1 and 2, and which contain the usual sound-absorbing pads 72, have a special end flange construction to enable them to be hung directly on the conduit. Each pan has end flanges 68 and semi-cylindrical extensions 70 projecting upwardly at intervals from flanges 68. The extensions are separated by spaces of a length equal to the width of the extensions. The extensions at one end of the pan are opposite the spaces at the opposite end. The extensions, as clearly shown in Fig. 1, project around the conduit to. a point beyond a plane passing through the axis of the conduit whereby they serve as hooks or hangers. When the pans are mounted on the conduit, the extensions of one pan interflt between the extensions of the other whereby both are accommodated. The extensions may be cut away at the locations of hangers 62 to permit them to pass around the conduit, as clearly illustrated in Fig. 2.

The instant invention provides planes of contact between the conduits and the pans, whereby the heat may pass by conduction to the metal pans. The pans form a heat-radiant surface overlying the room to provide for the transmission of heat by radiation to objects within the room. The construction combines with the generally known accoustical system without any adverse effect on its sound-absorbing characteristics.

The above description has been directed to systems employing a heated fluid as the heat source. However, other sources of heat may be used. For example, the conduits may contain electrical heating elements, suitably electrically insulated from the tubes.

Having thus described our invention in rather full detail it will be understood that these details need not be strictly adhered to and that various changes and modifications may suggest themselves to one skilled in the art, all falling within the scope of the invention as defined by the subjoincd claims.

2. In a panel ceiling for a heat transfer system including a plurality of spaced apart fluid conducting pipes and a plurality of panels arranged in a plane to form a ceiling surface, that improvement therein in which the panels have integral flanges oppositely disposed on the panel, said flanges having means including arcuate extremities providing support for the panels from the pipes and heat conduction between the pipes and the panels, at least part of the arcuate extremity of one flange of a panel facing in the same direction as at least part of the arcuate extremity of the oppositely disposed flange of said panel.

3. A radiant heating or cooling system for a space comprising a plurality of elongated temperature-modifying members, a thermally conductive panel, metallic means of high thermal conductivity providing a substantially direct path between said members and said panel and providing support means for the panel from the members said metallic means including integral flanges oppositely disposed on the panels, said flanges having arcuate extremities engaging said temperature-modifying mem bers, at least part of the arcuate extremity of one flange of a panel facing in the same direction as at least part of the arcuate extremity of the oppositely disposed flange of said panel.

4. A combined radiant heating or cooling and acoustic system for a space comprising a building structure, a plurality of elongated temperature-modifying members, a thermally conductive and substantially sound-pervious panel, metallic means of high thermal conductivity providing a substantially direct path between said members and said panel and providing support means for the panel from the members, said means including integral flanges oppositely disposed on the panels, said flanges having arcuate extremities engaging said temperaturemodifying members, at least part of the arcuate extremity of one flange of a panel facing in the same direction as at least aprt of the arcuate extremity of the oppositely disposed flange of said panel, and sound-absorbing material acoustically exposed to said panel between said panel and said structure.
