This invention generally relates to buildings and more particularly relates to heating and cooling a building.
There are many ways to heat or cool a living space. The current art includes furnaces, boilers, heat pumps, gas-fired space heaters, electric space heaters, wood-burning and pellet stoves, fire places, ductless, and radiant heating. Radiant heating is advantageous because it allows for greater efficiency and zoning, is silent, and doesn't circulate allergens.
Current art radiant heat systems are normally installed in floors, but are also installed in walls and the ceiling. Current art most often uses PEX pipes or another type of pipe. They are placed throughout the floor, wall, or ceiling. Water then circulates through the pipes varying in temperature to either heat or cool the surrounding living area. These systems offer no structural support for the buildings where they are installed. In addition, they represent a small portion of the surface area where they are installed. This can result in uneven heating, especially when objects are placed in front of or over top of the radiant heating/cooling system. For example, couches, bookshelves, and pictures or clocks that are hung on walls will impede the heating or cooling process.
Other known radiant flooring systems are configured such that the pipes are installed and concrete is laid over top of them to comprise the floor of the building or living area. This makes the installation process cumbersome and expensive, and also impedes the heating or cooling process. A radiant heat system is needed that may comprise the floor itself, so that minimal material is placed between the fluid—the source of the heating or cooling—and the living area.
A system is needed that comprises the entire surface area of a wall, ceiling or floor. Such a system will allow for more efficient and consistent heating and cooling. A system that can be easily manufactured with the fluid pathway integrated within the wall, floor, or ceiling panel could potentially simplify the manufacturing process, and reduce the total system cost. A radiant heat system which offers structural support for the building is also needed. Embodiments disclosed herein may improve performance of radiant heat systems.
This invention has been developed in response to the present state of the art and, in particular, in response to the problems and needs in the art that have not yet been fully solved by currently available systems and methods. Features and advantages of different embodiments of the invention will become more fully apparent from the following description and appended claims, or may be learned by practice of the invention as set forth hereinafter.
Consistent with the foregoing, a structure for heating or cooling a living area that simultaneously provides structural support for the building is disclosed. Rather than have pipes embedded inside the wall structure, the structural material itself is configured with parallel channels running through the panel. These channels allow fluid flow throughout the panel for heating or cooling the space.
The structure includes: A multi-layer wall structure, comprising an interior wall layer; a waterproof channel layer comprising adjacent parallel channels in communication with each other, a structural layer, a channel layer perpendicular to the waterproof channel layer, a thermal insulation layer, an outer layer, and an upper manifold and lower manifold in communication with the adjacent parallel channels and a remote fluid source.
The waterproof channel layer and channel layer perpendicular to the waterproof channel layer may be composed from different materials such as polycarbonate, acrylic, plastic, polypropylene, or non-wood materials. All these materials are waterproof and won't mold, mildew, or deteriorate when water or another hydronic fluid is run through the water proof channel layer. Additionally, the shapes of the channels may vary. The channels are parallel and evenly spaced, but the specific shape may be hexagon, octagon, triangle, quadrilateral, pentagon, heptagon, nonagon, decagon or another shape. The waterproof channel layer and channel layer perpendicular to it are designed such that the perpendicular channels add sheer strength to the structure.
The multi-layer wall structure also adds structural support for the building wherein it is placed. The sheer strength created by the waterproof channel layer and channel layer perpendicular to it, as well as the structural layer provide structural support. The fluid running from either the upper manifold to lower manifold or the lower manifold to the upper manifold is heated or cooled by a central water heating system. When it flows through the waterproof channel layer, the heat radiates into the living area in order to heat or cool the living space. The channel layer perpendicular to the waterproof channel layer and the thermal insulation provide insulation in the multi-layer wall structure. The air inside the channel layer perpendicular to the waterproof channel layer insulates. The thermal insulation layer may be a foam board, rigid foam, aluminum foil, or another insulating material that will reflect the heat inwards toward the living area. Furthermore, the structural layer will also reflect heat into the living area. It will be reflective itself, have a reflective coating, or a reflective film adhesively attached.
In order that the advantages of the invention will be readily understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments illustrated in the appended drawings. Understanding that these drawings depict only typical embodiments of the invention and are not therefore to be considered limiting of its scope, the invention will be described and explained with additional specificity and detail through use of the accompanying drawings, in which:
The description that follows includes systems, methods, techniques, instruction sequences, and computing machine program products that embody illustrative embodiments of the disclosure. In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide an understanding of various embodiments of the inventive subject matter. It will be evident, however, to those skilled in the art, that embodiments of the inventive subject matter may be practiced without these specific details. In general, well-known instruction instances, protocols, structures, and techniques are not necessarily shown in detail.
Reference throughout this specification to “one embodiment,” “an embodiment,” or similar language means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of the phrases “in one embodiment,” “in an embodiment,” and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment, but mean “one or more but not all embodiments” unless expressly specified otherwise. The terms “including,” “comprising,” “having,” and variations thereof mean “including but not limited to” unless expressly specified otherwise. An enumerated listing of items does not imply that any or all of the items are mutually exclusive and/or mutually inclusive, unless expressly specified otherwise. The terms “a,” “an,” and “the” also refer to “one or more” unless expressly specified otherwise.

One skilled in the relevant art will recognize that the embodiments may be practiced without one or more of the specific features or advantages of a particular embodiment. In other instances, additional features and advantages may be recognized in certain embodiments that may not be present in all embodiments.
The liquid that flows through the waterproof channel layer may be water or any other hydronic fluid which includes oil.
There are many existing radiant heating systems which use PEX pipe or other similar piping. The multi-layer wall structure is advantageous because it uses the entire surface area of the wall to radiantly heat or cool a living area. This will allow for greater flexibility when individuals living in, renting, or using the living area would like to add furniture, decorations, clocks, paintings, light fixtures, book shelves, cabinets or other furniture to the living area. In pex pipe radiant heating systems, the listed furniture causes a lot of problems because when the pipes only cover a very small portion of the surface area. Using furniture then blocks a greater percentage of the heat or cooling.
The water or other hydronic fluid may be pumped from the bottom manifold to the top manifold or from the top manifold to the bottom manifold. There are advantages with each embodiment. When the water is pumped from the top manifold to the bottom manifold, the flow of water does not have to work against gravity. This will make pumping the water downwards more efficient and save more energy for owners of a building with a multi-layer wall structure. However, it may also be advantageous to pump water or another hydronic fluid from the bottom manifold to the top manifold because individuals in the living area are on the floor, and so the warmest part of that wall would be nearest the people by pumping from bottom manifold to top.
There are various shapes that the channels of the waterproof channels may be shaped into the channels are parallel to one another and evenly spaced and cover the surface area of the wall, ceiling, or floor where they are installed. One special advantage of the waterproof channels when compared to current art radiant heating systems is the issue of a leak. Current art radiant heating systems are extremely costly to install and are most often laid in floors and covered with a layer of concrete. Not only does this inhibit the heating or cooling effects, but makes repair very expensive whenever there is a leak in the pipes. the only option when there is a leak is to remove the concrete and repair the individual pipe that is the source of the problem. In contrast, in the multi-layer wall structure, the channels through which the liquid flows are in communication with one another. That is to say, when there is a leak or a break in one of the channels, the liquid will flow into the channel adjacent to it and not out into the wall (which could cause molding, deterioration) thus small leaks in the multi-layer wall structure do not require reparation. This also makes the multi-layer wall structure less expensive to maintain than current art radiant heating and cooling systems.
The multi-layer wall structure may be used as an exterior wall or interior wall. In either embodiment, the thermal insulating layer is designed to direct the heat into the room that the waterproof channel layer is nearest. The channel layer perpendicular to the waterproof channel layer also contributes to directing the heat towards the intended room. This way, heat does not escape into a room or outdoor area behind the multi-layer wall structure. By using a thermal insulating layer, owners of a multi-layer wall structure can also use zoning, that is they can heat specific rooms that they need to without leaking a lot of heat into surrounding rooms an insulating layer may be a foam board. The foam board is also useful in its ability to dampen sound traveling through rooms. It will help to control noise from traveling from room to room. The channel layer perpendicular to the waterproof channel layer can also provide the insulation necessary to direct the heat into the living area.
The structural layer may also contribute to insulating. In the preferred embodiment, the structural layer is made from a metal that has the natural attribute of being reflective to direct heat into the living area. In another embodiment, the metal sheet layer has a reflective coating so that the desired effect is still achieved. Another embodiment includes a reflective material being placed over the structural layer which has reflective properties and will also direct the heat into the living area.
There are a number of ways to heat fluid in a building. Any current fluid heating system will work with the multi-layer wall structure. The hydronic fluid is pumped from the heating system to the upper or lower manifold. When the hydronic fluid exits the upper or lower manifold it is returned to the central water heating system and reheated or cooled to be circulated through the system again. Depending on the building type wherein the multi-layer wall structure is installed, one central fluid heating and cooling system may be preferred over another.
the multi-layer wall structure layers may be different than the order presented in various embodiments throughout the description contained herein. There are several embodiments that may be preferred depending on whether the multi layer wall structure is used as a ceiling, wall, or floor. The structural layer provides strength in addition to the sheer strength that is generated by the waterproof channel layer being perpendicular to the second channel layer. When the structure is used as a floor, the structural layer will be thicker to increase the maximum load bearing. The multi-layer wall structure as a floor will need to support more weight at any time because of furniture and a varying number of people in the room. The wall and ceiling will not need to bear that load. Additional sheer and loading strength is achieved by structurally or adhesively connecting vertical channel layers with adjacent horizontal channel layers. Many examples of this are shown both in these written specifications and drawings contained herein.
These features and advantages of the embodiments will become more fully apparent from the following description and appended claims, or may be learned by the practice of embodiments as set forth hereinafter.
