The present invention relates generally to a hydronic radiant heating and/or cooling system. More specifically, the present invention relates to a hydronic radiant heating and/or cooling system formed from prefabricated radiant heating and/or cooling structures that may link to each other such that there is fluid communication between the structures.
U.S. Pat. No. 6,182,903 to Fiedrich, discloses a hydronic radiant heating and/or cooling system comprising modular panels. Each modular panel comprises a metal plate or sheet on a board or boards providing a slot into which tubing is inserted and held against the plate in intimate thermal contact therewith. The plate is heated/cooled by conduction of heat between the water in the tubing and the plate. Two or more sets of hinged panels unfolded at their hinges and arranged end to end provide elongated spaces into which the tubing is inserted and held against the radiation plate. The panels of a set are arranged in a regular staggered relationship so that such sets unfolded and arranged end to end abutting each other interlock.
U.S. Pat. No. 7,832,159 to Kayhart, discloses an in-floor radiant heating system having a tube that is received into low profile panels. Channels are formed in the top of the panels. The channels can have a neck shaped top section and a circular shaped bottom section. The bottom section has a diameter that is larger than the width of the top section. The diameter of the tubing is smaller than the diameter of the bottom section to ensure a snug fit.
It is desirable to provide a panel system having a more direct means for transferring thermal energy between a thermal source and a room or some external environment than the tubing systems described in the art. A panel system that maximized thermal transfer by minimizing mediums through which the thermal energy needed to pass would generate the desired result.
In one aspect of the present invention, a radiant climate control system comprises a panel system; comprising a first and a second panel. The first panel may comprise an attachment surface. At least one impermeable channel may be formed in the attachment surface. The at least one impermeable channel may be open along the attachment surface. The second panel may be attached to the attachment surface and cover at least a portion of the at least one impermeable channel. A portion of the second panel covering the channel may be impermeable. The second panel may have a greater thermal conductivity than the first panel to promote thermal energy transfer between a fluid in the impermeable channel and an environment proximate the panel system through the second panel.
The panel system may be joined with a compatible panel system, and the impermeable channel of the first panel may be mated with a compatible channel of the compatible panel system, thereby allowing fluid communication between the panel system and the compatible panel system. The impermeable channel of the first panel may be mated with the compatible channel of the compatible panel system by a sealing fixture.
In some embodiments, the first panel may comprise a foam such as a polystyrene foam, a polymeric foam, a composite foam, a metal foam, or a ceramic foam.
In some embodiments, the channel has a breadth no wider than at an opening of the impermeable channel and the breadth may continually narrow as it extends from the opening of the impermeable channel.
In some embodiments, the impermeable channel has a supply end and a return end. The supply end may be in fluid communication with a fluid supply line, and the return end may be in fluid communication with a fluid return line. The impermeable channel may have a supply end in fluid communication with a fluid supply line and a return end in fluid communication with the compatible channel of the compatible panel system. Valves may connect the supply end to the fluid supply line and the return end to the fluid return line.
In some embodiments, the impermeable channel is substantially parallel with at least one additional channel. The impermeable channel may be interconnected with at least one additional channel. The impermeable channel may be spaced substantially evenly from a plurality of additional channels.
In some embodiments, the impermeable channel opens up into a cavity. The cavity may have a pillar disposed within the cavity. The pillar may structurally support the second panel. The cavity and the impermeable channel may have rough interiors.
In some embodiments, the first panel is supported by a first beam and a second beam disposed on opposing sides of the first panel. The panel system may be structurally supported by the compatible panel system.
The first panel 202 may comprise an attachment surface 204 that may form a side of the first panel 202 that is closest to an environment to be heated or cooled. The attachment surface 204 may comprise at least one impermeable channel 205 formed in the attachment surface 204. A surface of the impermeable channel 205 may be consubstantial with the first panel 202 in that the first panel 202 may comprise a material impermeable to fluid. In other embodiments, the first panel 202 may not be formed of an impermeable material and the impermeable channel 205 may be formed by spraying, lining, or coating the channel with an impermeable material.
A fluid may flow through the impermeable channel 205. The impermeable channel 205 may prevent the fluid from being absorbed by the first panel 202. Preventing the first panel 202 from absorbing the fluid may increase the life of the panel system 201 and decrease the amount of heat loss in the panel system 201. Decreasing heat loss in the panel system 201 may increase the efficiency of the radiant heating process.
The second panel 203 may be attached to the attachment surface 204 and may cover at least a portion of the impermeable channel 205. The second panel 203 may also seal an opening 206 of the impermeable channel 205. In some embodiments, a portion of the second panel 203 covering the impermeable channel comprises an impermeable surface. The impermeable surface may prevent the fluid that is passing through the impermeable channel 205 from being absorbed by the second panel 203.
The panel system 201 may be joined with at least one compatible panel system 207. The panel systems 201 and 207 may be joined by welding, joining, bolts, other processes, or combinations thereof. The panel system 201 may be structurally supported by the compatible panel system 207. This structural support may form a more stable base for the structure since shifting of the panel system 201 with respect to the compatible panel system 207 may cause stresses to arise in the panel system 201. Joining the panel system 201 with the compatible panel system 207 may prevent shifting and reduce the probability of premature failure of the panel system 201.
The impermeable channel 205 may comprise a supply end 209 and a return end 210. The supply end 209 may be in fluid communication with a fluid supply line 211, and the return end 210 may be in fluid communication with a fluid return line 212. The panel system 201 may also have valves connecting the supply end 209 to the fluid supply line 211 and the return end 210 to the fluid return line 212.
The impermeable channel 205 of the first panel 202 may be mated with at least one compatible channel 208 of the compatible panel system 207. Mating channels 205 and 208 may allow fluid communication between the impermeable channel 205 and the at least one compatible channel 208. The mated channels 205 and 208 may only require a single fluid supply line 211 and a single fluid return line 212. The single fluid supply line 211 and the single fluid return line 212 may transport fluid from a fluid source to the panel system 201 and the compatible panel system 207. Minimizing the amount of supply and return lines may decrease the amount of energy required to pump the fluid through the system and decrease thermal energy losses in the system.
In the embodiment shown, the impermeable channel 205 is substantially parallel with at least one additional channel 215. The impermeable channel 205 may be spaced substantially evenly from a plurality of additional channels. Such spacing may arrange the impermeable channel 205 and the at least one additional channel 215 such that the fluid transfers thermal energy substantially uniformly through the second panel 203. Transferring thermal energy substantially uniformly may create a substantially consistent environment superjacent the panel system 201. The impermeable channel 205 may be interconnected with at least one additional channel to allow the fluid flow to be controlled and to therefore control the transfer of thermal energy to the environment superjacent the panel system 201. The impermeable channel 205 and the at least one additional channel 215 may be disposed to meet specific needs of the structure.
The impermeable channel 305 may comprise an opening 306, a base 314 and side walls 315. A breadth of the impermeable channel 305 may be defined as the distance between the side walls 315 at a given depth in the impermeable channel 305. The breadth may be widest at the opening 306. The breadth of the impermeable channel 305 may continually narrow as it extends from the opening 306 towards the base 314. The side walls 315 may connect the opening 306 and the base 314. The side walls 315 may have a curved shape.
In some embodiments, the first and second beams are I-beams. I-beams may have a similar geometry to two C-beams that have been interlinked. I-beams may reduce the amount of labor required to assemble the system by omitting the process of interlinking the beams. I-beams may have reliable mechanical properties that have not been altered by welding or joining processes.
The at least one pillar 727 may cause a turbulent fluid flow 717 through the cavity 726. A turbulent fluid flow 717 may circulate the fluid in the cavity 726 such that the fluid on an upper portion 718 of the cavity 726 may move to a lower portion 719 of the cavity 726, and the fluid in the lower portion 719 of the cavity 726 may move to the upper portion 718 of the cavity 726 where it may come in contact with the second panel 703. Hence, fluid from the upper and lower portions 718 and 719 of the cavity 726 may conduct thermal energy to the second panel 703. Thermal energy transfer from both portions of the cavity may more efficiently transfer the thermal energy from the fluid.
In various embodiments, the panel system 1001 may be disposed in an upper portion of a wall 1029, in a ceiling 1032, or in a space above the ceiling 1032 within the building structure 1000. The panel system 1001 may transfer thermal energy into the air proximate the panel system 1001 causing the temperature of the air to increase. As the air proximate the panel system 1001 becomes heated it may rise. Air below the heated air may rise to fill a void left by the heated air. These events may repeat and result in a cycle that causes a circulation 1035 of air in the building structure 1000. The circulation 1035 may heat the environment within the building structure 1000. In some embodiments, a panel system is configured to cool the air proximate the panel system which may cause a circulation that cools the environment within a building structure.
