HEATING AND COOLING OF BULISDINGS Filed May 21. 1928 kg k/ 24 lie 2/ J2 duly lltlllfl EUSEPE, LESLIE MUSGRAVE AND RICHARD GODFREY CRITTALL, 01E LONDON, ENGLAND HEATING AND COOLING 0F BUILDINGS Application filed May 21, 1928, Serial No. 279,552, and in Great Britain June 1, 1925.
This invention has reference to the heating and cooling of buildings in which a heating or cooling fiuidis caused to circulate through a system of pipes embedded in a material forming the floors, walls, or ceilings of such building and from the surface of which material the heat or cold radiates, and in particular refers to the system of heating or cooling known as panel heating.
Hitherto in this system of heating the material with which the pipes are covered or embedded. and from the surface of which the heat or cold. radiates has been laid on. while in a plastic state.
Now according to this invention instead of covering the pipes through which the heating or cooling fluid circulates with a material while in a plastic state we encase the pipes with a covering made in sections ready so for erection. These sections, which. form the finished surface of the wall, floor or ceiling from which the heat radiates, are moulded or otherwise made in the workshop from fibrous plaster or other suitable material of 25 a more or less heat conducting nature, a groove or grooves, or channel or channels be ing formed on the inner surface of each section to fit over or on to the pipes.
When installing the system the pipes are so first fixed against the surface or structure of the building, preferably by metallic straps or saddles, and then the sections are placed in position, the grooves or channels in the sections fitting over the pipes. Before placing the sections in position contact is made between the pipes and the grooves in which they fit by inserting into such grooves or channels a small quantity of plastic material or equivalent which will transmit the heat or cold from the pipes to the material from which the sections are made, thus enabling such heat to radiate from the surface of said sections.
lln a modified form of our invention we may use metallic sections. In which case we may dispense with the grooves or channels, contact between each pipe and the inner surface of the sections being made by a small quantity of plastic material or equivalent.
' dles by which the pipes or tubes B are fixed against the surface of the structure A, and D the section which encloses the pipes or tubes and which forms the finished surface of the wall, floor or ceiling from which the heat or cold radiates.
At Fig. 1 we have shown the pipes or tubes B enclosed in a section D mouldedor other wise formed in the workshop from fibrous plaster or other suitable material of a more or less heat conducting nature. These sections D are made in the workshop ready for erection with grooves or channels cl formed in the inner surface to enable them to be fitted over the pipes B, as clearly shown.
When installing the system the pipes B are first fixed against the surface of the building structure A by straps b then when a small quantity of plastic material d or equivalent has been inserted into the grooves or channels d formed in the back of the section D, such section D is placed in position, the plastic material 6Z2 making contact between the pipes and the grooves 03 thus transmitting the heat or cold from the pipes to the section D, from the surface of which see-- ion the heat or cold radi .tes. The batches of plastic material (1 which are placed in the grooves 73 are brought into contact with the pipes, thereby pressing the plastic material against the pipes, as seen in Fig. 1, sothat the plastic material extends partly around the pipes and is formed with grooves in which the pipes are disposed.
At Fig. 2 we have shown the section D constructed of metal, which section may be cured in position. in the manner shown or by lllltl 2 f Y .Q 1,771,269
other means. As illustrated on the drawing we may dispense with grooves or channels in the section and make contact between the pipes B and said section by interposing a 5 small quantity of plastic material (Z or equivalent between each pipe and the inner surface of such section/ What we claim as our invention and desire to secure by Letters Patent is 1. The combination with abuilding structure, of heating orocooling pipes disposed at the, surface of said structure, a covering of heat-conducting material extending across said pipes, and batcheszof heat-conducting 5 material disposed between and contacting with said covering aridpipes.
. 2. The combination with a building structure of heating 'orcooling pipes disposed at the surface'of said structure, a covering of heat-conducting material extending across said pipes'and having grooves receiving said pipes, and heat-conducting material disposed etween said covering and pipes in said grooves.
26 3. The combin'ationwith a. building structure, ofheatin'g or cooling pipes disposed at the surface of said structure, a covering of heat-conducting material extending across said pipes, and batches of plastic material 30 placed between and contacting with said pipes and covering.
4. Thecomhination with a building structure, of heating or cooling pipes disposed at the surface of said structure, a covering of heat-conducting material extending across said pipes, and'batches of heat-conducting material disposed between and contacting with said covering and'pipes and having grooves in which the pipes are disposed.
4 5. The combination with a building structure of heating or cooling pipes disposed at the surface of said structure, a covering of heat-conducting -material extending across said pipes, and'batches of material carried by said covering and pressed against said pipes. I p
In testimony whereof we have signed our names to this specification.
