"3 m r Patented June 3, 1952 UNITED} STATES PATENT oFFi cs RADIANT HEATING SYSTEM Lewis L. Scott, St. Louis, Mo. I Application April 7, 1949, Serial No. 85,949 a 3 Claims. (Cl. 237-69) This invention relates particularly to a system for heating homes, apartments and the like.
This invention is a modification and improvement on my'application No. 67,840,"filed December-29, 1948, now abandoned. r 7
"One of the objects of my invention is to providea simple steam boiler and a horizontal steam coil to replace hot water boilers and coils before used.
- Another object is to provide an accessible fire stop locatedbelow the heat coil. v
A still further object is to provide a totally enclosed air system so that the air to the heating coil will be returned through a duct system directly to the coil. By so doing, dust from the basement will be kept out of the system and. the basement will be heated by radiant heat from the basement ceiling.
In the accompanying drawings:
Figure I is a cross section of a two-story house with basement. In order to conserve space, a section of thefirst and second floors has been broken away.
Figure-2 is a section, onthe line 2-2 of Figure 1; of the ceiling of the first floor.
Figure 3 is a section, on the line 3-3- of Figure-Lot the floor of the first fioor, showing the return air duct.
Figure 4 is a section, on the line 4-4 of Figure 1, of the vertical heat shaft running from the basement to the ceiling of the first floor. This figure shows insulation, studs and plaster not shown, in the section of the heat shaft in Figure 1.
Referring to the drawings, the letters A, B and C indicate the basement, first fioor and second floor, respectively.
The numeral I is a steam boiler which is connected to a steam heat transfer coil 2 by the steam pipe 3 and the return condensate pipe 4. In the return pipe 4, I locate a well-known air relief vent valve 5, which valve is located up between the joists of the basement ceiling and above the steam coil 2. I also locate a check valve A in the return line 4 near the boiler I. 5 indicates automatic air shutters which are pivoted at 1 and which are held together by rod 8. 9 indicates a weight attached to one of the shutters 6. The wire I0 is secured to the weight 9 and also to the side of the coil case at ll. [2 is a fusible link attached at the central part of the wire l0. Under normal operation, air at normal temperature will pass up through the space between the shutters 6. However, should there be abnormally high air temperatures, the
, v 2 fuse l2 will fuse and the weights will cause the shutters to close and shut 01f the air going-to the steam'coil 2. I
They boiler l can'be heated byany type of burner, such as oil, gas or coal, not shown. I v v The temperature of the rooms is to be controlled by the'usual room thermostat, not shown, which controls the operation of the burner.
l3 indicates the basement wall or foundation. The joists M are carried by the wall l3 and support the floor It. The steam coil 2' and its frame [6 are supported from the joists IA. The heat shaft l'l communicates with the steam coil 2 and runs up through the first floor to the first floor ceiling. [8 indicates insulation in the top of the heat shaft which is used to prevent a hot spot above the heat shaft on the second'fioor at that point. Woodmembers I9 which may be 2'." X 2" are attached'to the ceiling joist 2B and at right angles to said joist. Since the members .are spaced fromeach other as illustrated in Figure 2,
. there are passageways between said members and also between the ceiling joist 26. The first floor ceiling 2! is secured to the members 19. In view of this construction, the-heated air passing up the shaft H can travel through the joist space and also at right angles to the'joist space in any direction toward any of the outside walls of the building and down through the spaces 22 between the vertical studs and through the fire stop doors 23 into the duct 24 and through the shutters 6 to the intake side of the coil 2.
The numeral 25 indicates a stop plate between the vertical studs and in line with the fioor of the second floor, to prevent upward travel of the air in the spaces 22 between the studs.
The vertical heat shaft liner HA is usually made of aluminum foil insulation and stapled to the vertical studs 26 (see Fig. 4). The numeral 21 indicates insulation. The numeral 18 designates the plaster around the shaft l1 and the insulating material.
Element 29 is the ceiling of the second fioor which is usually insulated as shown at 30. The numeral 3| indicates the roof rafters and 32 is the roof of the building.
It will be noted from the above description that I have provided a totally enclosed air system for producing radiant heat from the floor of the second fioor and from the ceiling of the first floor and also from the floor of the first floor and the ceiling of the basement. It will be further noted that with this arrangement, basement dust will not be picked up by the flow of the air and deposited in the heat coil and that tending transversely thereof,
terior walls and an enclosed space immediately below the floor of the lower level and extending transversely thereof, said system including a main air duct located inwardly and remote from said exterior walls extending from immediately below the floor of the lower level and terminating at the floor of the upper level, a heating element in the lower part of said main duct, passageways extending transversely in the upper level floor-ceiling space in communication with the upper end of said main duct, and passageways in the hollow exterior walls communicating with said lastnamed passageways at their upper ends and with the enclosed space below the lower level floor at their lower end, the enclosed space below the lower level floor being in communication with the lower end of the main air duct whereby a heated air stream is moved through said closed system and returned for reheating by gravity flow induced by the temperature gradient of the stream.
2. A closed system of the class described for temperature conditioning of buildings, which includes enclosed spaces on at least'three levels, said system including a main vertical air duct located remote from the outer walls of said enclosed spaces and extending upwardly from immediately'below the floor of the second level to the floor of the upper level, a heat-exchanger located in the lower part of said main duct, a series of lateral ducts extending horizontally from the ,upper discharge end of said main duct, a second series of horizontal ducts in communication with said lateral ducts exsaid last two named series of ducts underlying the entire floor area of said upper level, a series of vertical ducts in the outer walls of the building in communication with said two series of horizontal ducts, and a closed horizontal duct underlying the floor of the second level communicating at its outer end with said vertical ducts and arranged to conduct the air stream into heat-exchange relation with said heat-exchanger.
3. In a closed system of the class described for temperature'conditioning of buildings, which includes enclosed spaces on at least three levels, said system including a main vertical air duct located remote and inwardly from the outer walls of said enclosed spaces and extending upwardly from adjacent the floor of the second level to the floor of the upper level, a heat-exchanger located in the lower part of said main duct, a series of lateral ducts extending horizontally from the upper discharge end of said main duct, and underlying the floor area of said upper level and extending transversely thereof, a series of vertical ducts in the outer'wallsof the building in communication, with said {series of horizontal ducts, a closed horizontal ductunderlying the floor of the second level and extending transversely thereof communicating at its outer end with said vertical ducts and at its inner end with the main duct to conduct the air stream for heat-exchange relation with said heat-exchanger whereby a heated air stream is moved through said closed system and returned for reheating by gravity flow induced by the temperature gradient of the stream.
