Description

The present invention relates to a floor heating panel, a floor heating system, a panel, and a method for constructing a floor heating panel, which are installed under a floor of a house or the like and perform heating of a floor and a room using hot water.

Conventionally, a floor heating system that heats the floor and the room by installing a floor heating panel that circulates hot water under the floor finishing material has been put into practical use. The floor heating panel needs to efficiently transfer the heat of hot water to the floor and suppress the escape of heat to the bottom of the floor as much as possible. Have been devised.

FIG. 14 is a cross-sectional view of a conventional floor heating panel 80. The floor heating panel 80 mainly includes a base material 81, a heat transfer plate 85, a heat equalizing plate 91, a pipe 89, and the like. The base material 81 has a pipe groove 83 and a heat transfer plate 85 is installed. The heat transfer plate 85 is a flat plate portion 93 having flat plate ends at both ends, and has an inverted Ω (omega) shape having a recess 87 at the center. The recess 87 of the heat transfer plate 85 is fitted into the pipe groove 83 of the base material 81.

The pipe 89 is fitted into the recess 87. The soaking plates 91 a and 91 b are attached to the upper surface of the base material 81 and the upper surface of the flat plate portion 93 of the heat transfer plate 85. That is, the soaking plates 91a and 91b have functions of fixing the heat transfer plate 85 to the base member 81 and in surface contact with the heat transfer plate 85 to diffuse heat in the surface direction. It should be noted that the heat equalizing plates 91a and 91b are not attached to the recess 87 of the heat transfer plate 85, and the pipe 89 is exposed.

When hot water is caused to flow through the pipe 89, the pipe 89 transfers heat of the hot water to the heat transfer plate 85, and further transfers heat from the heat transfer plate 85 to the heat equalizing plate 91 to dissipate heat. The radiated heat warms a floor finishing material (not shown), and has the effect of floor heating.

As another floor heating panel having such an effect, for example, a pipe is accommodated in a recess provided in a base material, and a soaking sheet material covering the pipe and the base material is attached, and the diameter of the pipe is adjusted to the depth of the groove. There is a tatami floor heating panel in which the soaking sheet and the upper part of the pipe are in surface contact with each other by making the pipe larger (Patent Document 1).

Also, a plurality of protrusions that support the heat radiating pipe are provided at the lower part of the groove provided in the base material, a heat radiating pipe having an outer diameter larger than the groove depth is accommodated in the groove, and a sheet member is attached on the base material and the heat radiating pipe. In addition, there is a floor heating mat in which the upper portion of the heat radiating pipe is in surface contact with the sheet member due to deformation of the heat radiating pipe (Patent Document 2).

In addition, heat conductive paper is provided in the piping groove of the panel-shaped heat insulating material, a copper hot water pipe is disposed on the heat conductive paper, a heat conductive plate is provided so as to cover the panel heat insulating material, the heat conductive paper, and the hot water pipe. There is a floor heating panel in which an upper part of a pipe and heat conductive paper are brought into contact with a heat conductive plate (Patent Document 3).
JP 2002-31360 A JP 2004-28524 A JP 2003-322349 A

However, since the tatami floor heating panel described in Patent Document 1 makes the pipe and the soaking sheet material contact at the upper part of the pipe, it is necessary to affix the soaking sheet material after the pipe is installed. Construction on-site is difficult and installation layout is less flexible, and heat transfer from the pipe is radiated only through the heat-equalizing sheet member, so there is a limit in heat transport and efficiency is low There is a problem.

Moreover, although the heat conductive mat of patent document 2 has the effect which suppresses the heat transfer from a heat radiating tube to a base material by the support part provided in the groove | channel, it is a sheet | seat after heat radiating tube installation similarly to patent document 1. Because it is necessary to affix the members, there are problems in terms of workability and installation layout flexibility, and heat from the heat radiating pipe passes only through the sheet members, so there is a limit to the amount of heat transport and it is said that efficiency is bad There's a problem.

In addition, the floor heating panel described in Patent Document 3 can transfer heat from the copper tube from both the heat conductive paper and the heat conductive plate by using the heat conductive paper. Since it is necessary to provide a heat conducting plate on the upper part of the copper tube, there is a problem that the workability is poor and the degree of freedom in installation layout is low as in the case of Patent Document 1 and Patent Document 2 described above. In addition, copper pipes are expensive and difficult to bend, and if a bender is not used, the cross-section will be crushed and the curvature of the bent part will not be stabilized instead of manual work. Cannot be bent to dimensions that match Since the copper tube and the heat conducting plate are in point contact, there is a problem that the heat transfer efficiency is low.

Furthermore, according to the floor heating panel 80 described above, the pipe 89 is exposed upward, and the pipe 89 can be installed at the site where the floor heating panel 80 is installed. Although the degree of freedom of installation of 89 is high, since the heat equalizing plate 91 and the pipe 89 do not contact, the heat from the pipe 89 is transferred to the heat equalizing plate 91 via the heat transfer plate 85, so that the heat efficiency is low. There is. In addition, since the contact area between the heat transfer plate 85 and the base material 81 is large, there is a problem that heat from the pipe 89 escapes to the base material 81 and the heat transfer efficiency to the soaking plate decreases.

The present invention has been made in view of such a problem, and heat from the fluid in the pipe can be efficiently radiated to the floor, and the pipe can be arranged on the site. An object of the present invention is to provide a floor heating panel having a high workability and a high degree of freedom in pipe construction, and with little variation in quality.

Heat is transferred to the hot plate, and the heat transfer efficiency to the soaking plate is increased by forming a plurality of heat flow paths. Moreover, since the deformation of the heat transfer member is suppressed by the rib of the heat transfer member and the outer peripheral surface of the concave portion of the heat transfer member does not come into contact with the groove provided on the base material, there is almost no heat escape to the base material, and the pipe Since there is no step of attaching a soaking plate on the top surface and pipes can be installed on site, it is possible to provide a floor heating panel with excellent workability and high heat efficiency with high pipe installation freedom. .

A second invention is a floor heating system comprising the floor heating panel according to the first invention and means for circulating fluid to the floor heating panel.

According to the second aspect of the invention, since the pipe contacts the heat transfer member and also the heat equalizing plate, the heat from the pipe is directly transferred to the heat equalizing plate and is also transferred via the heat transfer member. Heat is transferred to the hot plate, and heat transfer efficiency is high due to the formation of multiple heat flow paths, and the heat transfer member does not come into contact with the groove of the base material, so there is almost no heat escape to the base material. It is possible to provide a floor heating system with excellent thermal efficiency, in which there is no step of attaching a soaking plate, and pipes can be arranged on site.

A panel comprising: a fitted heat transfer member; and a heat equalizing plate provided across the base material and the flat plate portion and having a cut at a position corresponding to the concave portion. .

According to the third invention, since the heat transfer member has the rib, the deformation of the heat transfer member is suppressed, and the rib of the heat transfer member and the outer peripheral surface of the concave portion of the heat transfer member do not contact the base material. There is almost no heat escape from the surface to the base material, there is no process of attaching a heat equalizing plate to the upper surface of the pipe, and pipe installation is possible on site, so it is excellent in workability and has high flexibility in pipe installation The panel which is a member for floor heating panels excellent in thermal efficiency can be provided.

4th invention has the base material which has a groove | channel, and provided on the said base material, has a recessed part and the flat plate part provided in the both sides of the said recessed part, The said recessed part is a groove | channel provided in the said base material. A pipe provided at a position corresponding to the cut of a panel comprising: a fitted heat transfer member; and a heat equalizing plate provided on the base material and the flat plate portion and having a cut at a position corresponding to the recess. The floor heating panel construction method is characterized in that the pipe is pushed into the cut and the pipe is fitted into the recess.

According to the fourth invention, since it is possible to attach a soaking plate having a cut before installing the pipe, it is possible to install the pipe on-site and attach the soaking plate after installing the pipe. Since there is no work, it is excellent in workability on site, and it is possible to change the pipe arrangement according to the shape of the site, so the degree of freedom of pipe arrangement is high, and the pipe after installation is a recess in the heat transfer member Since it is in contact with the inner peripheral surface and the soaking plate, the heat from the pipe is directly transferred to the soaking plate, and is also transferred to the soaking plate via the heat transfer member. The construction method of a floor heating panel with high thermal efficiency can be provided by forming a plurality of paths.

For this reason, when there is a slight difference between the construction site and the drawing, or when it is necessary to change the design according to the request of the owner at the site, the layout of the pipes is changed by cutting the panel according to the site shape. Therefore, the degree of freedom of pipe placement is high and the workability on site is excellent. In addition, since the pipe after installation is in contact with the inner peripheral surface of the heat transfer member recess, and also in contact with the heat equalizing plate, the heat from the pipe is directly transferred to the heat equalizing plate and via the heat transfer member. Heat is transferred to the soaking plate, and a plurality of heat flow paths are formed, thereby providing a method for constructing a floor heating panel with high thermal efficiency.

Hereinafter, embodiments of the present invention will be described in detail. FIG. 1 is a diagram showing a floor heating system 1 according to an embodiment of the present invention, FIG. 1 (a) is a perspective view of the floor heating system 1, and FIG. 1 (b) is in FIG. 1 (a). It is A section sectional drawing.

The floor heating system 1 includes a floor 3 composed of a floor heating panel 13 and the like, an outdoor unit 23 installed outside the room, a pipe 21 connecting the outdoor unit 23 and the floor heating panel 13, and the like.

In the floor 3, a joist 9 is provided in a beam shape on a plate-shaped receiving plate 5, and a rough floor 7 is provided on the joist 9. A heat insulating material 11 is provided at a portion other than the joist 9 between the receiving plate 5 and the rough floor 7. A plywood 15 and a floor heating panel 13 are provided on the rough floor 7. The floor heating panel 13 is installed in an indoor floor heating range, and a plywood 15 having the same thickness as the floor heating panel 13 is installed around the floor heating panel 13. Therefore, the plywood 15 and the floor heating panel 13 are flat.

A floor finishing plate 17 is provided on the plywood 15 and the floor heating panel 13. The floor finish plate 17 is the surface of the floor 3 of the room. The floor heating panel 13 is provided with a pipe 19 that meanders over the entire surface of the floor heating panel 13. The pipe 19 is connected to the outdoor unit 23 via the pipe 21. The outdoor unit 23 includes a heat exchanger (not shown) that warms warm water by combustion of gas or the like, a pump that circulates warm water, and the like. The hot water generated in the outdoor unit 23 is caused to flow to the pipe 19 provided in the floor heating panel 13 through the pipe 21 by a pump. Under the present circumstances, the header etc. which are not shown in figure are provided so that a warm water can be branched to the some piping 21 as needed. Instead of the outdoor unit 23, an indoor unit having the same function can also be used.

The hot water flowing through the pipe 21 and flowing into the pipe 19 dissipates heat to the floor finishing plate 17 when flowing through the floor heating panel 13, the surface of the floor 3 is warmed, and the floor 3 and the room can be heated. . At this time, heat radiation is suppressed in the lower floor direction by the heat insulating material 11 between the rough floor 7 and the receiving plate 5. That is, the floor heating system 1 transfers the heat of the hot water flowing through the installed floor heating panel 13 to the floor finishing plate 17 above the floor heating panel 13 as efficiently as possible, and the rough heating below the floor heating panel 13. Since heat radiation to the floor or the like is a heat loss, it is desirable to suppress it as much as possible.

FIG. 2 is a cross-sectional view of the floor heating panel 13. The floor heating panel 13 is mainly composed of a base material 25, a heat transfer member 27, a pipe 19 and a soaking plate 29. The base material 25 is a heat insulating member, and has a pipe groove 31, a rib groove 33, and the like along the outer shape of the heat transfer member 27. The heat transfer member 27 is a member having an inverted Ω (omega) shape having a flat plate portion 28 at both ends and a concave portion 35 at the center. A plurality of ribs 37 are provided on the lower surface of the flat plate portion 28 of the heat transfer member 27. The rib 37 is for obtaining the strength of the heat transfer member 27.

The heat equalizing plate 29 is a thin plate-shaped heat transfer member, and an adhesive is applied to one surface thereof. The heat transfer member 27 is installed in the base material 25 so that the recess 35 of the heat transfer member 27 is fitted in the pipe groove 31 of the base material 25 and the rib 37 is fitted in the rib groove 33. At this time, the upper surface of the flat plate portion 28 of the heat transfer member 27 and the upper surface of the base material 25 substantially coincide. That is, there is almost no step at the boundary between the heat transfer member 27 and the substrate 25. Further, a clearance 32 is provided between the outer peripheral surface of the concave portion 35 of the heat transfer member 27 and the surface of the pipe groove 31 of the base material 25 to disconnect the heat transfer member 27 and the base material 25 from contact with each other. A clearance 34 is also provided between the rib 37 and the surface of the rib groove 33. That is, an air layer having a heat insulation effect with poor thermal conductivity is provided between the heat transfer member 27 and the substrate 25.
The clearance provided between the outer peripheral surface of the concave portion 35 of the heat transfer member 27 and the base material 25 is preferably provided over the entire circumference of the outer peripheral surface of the concave portion of the heat transfer member 27. However, the base material 25 is thermally conductive. It is possible to make a part of the contact as long as the overall heat insulation is not impaired.

The pipe 19 is fitted into the recess 35 of the heat transfer member 27. Although details will be described later, since the outer diameter of the pipe 19 is larger than the width of the entrance of the recess 35, the pipe 19 does not come out of the recess 35. That is, the heat transfer member 27 has a function of holding the pipe 19 as well as a heat conduction function described later. The heat equalizing plate 29 is attached so as to cover the upper surface of the flat plate portion 28 of the heat transfer member 27 and the upper surface of the base material 25, and the end portion is bent between the recess 35 and the pipe 19. Therefore, the heat equalizing plate 29 has a function of fixing the heat transfer member 27 to the base material 25 as well as a heat conduction function described later.

The end portion of the heat equalizing plate 29 is folded into the recess 35 and comes into contact with the pipe 19. That is, the pipe 19 is in contact with the heat transfer member 27 in the vicinity of the lower portion of the recess 35 to form a heat transfer member contact portion 39 and the end portion of the heat equalizing plate 29 folded between the pipe 19 and the recess 35. The soaking plate contact portion 41 is formed by contact.

Here, the material of the base material 25 should just have a heat insulation effect, for example, a foamed polystyrene can be used. Moreover, the material of the heat transfer member 27 should just have a certain amount of intensity | strength and heat conductivity, for example, can use aluminum, Preferably, the JIS A6063-T5 material excellent in intensity | strength and heat conductivity can be used. For the heat transfer member 27, for example, an extruded profile can be used. If the thickness is too thick, the weight and cost increase. If the thickness is too thin, the manufacturability, strength, and thermal conductivity are adversely affected. Those having a thickness of about 8 mm can be used. The ribs 37 provided on the flat plate portion 28 of the heat transfer member 27 also have an effect of increasing the shape stability during extrusion of the extruded shape member and the rigidity of the heat transfer member 27.

The soaking plate 29 only needs to have thermal conductivity and a certain degree of bendability. For example, aluminum can be used. Preferably, JIS A1N30-O material or H1X tempered material which is relatively soft and excellent in thermal conductivity is used. can do. If the thickness of the heat equalizing plate 29 is too thick, the weight and cost increase, and it becomes difficult to form a bent portion at the end, and if it is too thin, there is a problem in thermal conductivity and handleability. . About 15 mm can be used. The adhesive applied to the soaking plate 29 may be any adhesive as long as the substrate 25, the heat transfer member 27, and the soaking plate 29 can be bonded. For example, an acrylic adhesive can be used.

The material of the pipe 19 should just have the heat resistance which does not corrode with warm water and can endure the heat | fever of about 80 degreeC, For example, resin pipes made from polyethylene, a product made from polybutene, etc. can be used. Although a copper pipe or the like can be used, a pipe made of resin is preferable because it requires bending and welding of the pipe and the pipe itself is also expensive.

Next, the usage status of the floor heating panel 13 will be described.
FIG. 3 is a cross-sectional view showing a state in which hot water 43 that is a fluid is caused to flow through the pipe 19 of the floor heating panel 13. When hot water 43 is allowed to flow through the pipe 19, heat is transmitted through the following two routes, radiated from the heat radiating portion 45, and warms the floor finishing material 17 and the like (not shown). First, in the first heat transfer route, the heat of the hot water 43 is transferred from the pipe 19 to the heat transfer member 27 via the heat transfer member contact portion 39 (arrow B in the figure). The heat transferred through the heat transfer member 27 by heat conduction is transferred to the soaking plate 29 attached to the upper part in the vicinity of the flat plate portion 28 (arrow C in the figure). The heat transmitted to the heat equalizing plate 29 is dissipated from the heat dissipating portion 45 located above the heat soaking plate 29 and warms the floor finishing material 17 and the like not shown.

On the other hand, in the second heat transfer route, the heat of the hot water 43 is directly transferred from the pipe 19 to the heat equalizing plate 29 via the heat equalizing plate contact portion 41 (arrow D in the figure) and radiated from the heat radiating portion 45. Then, the floor finishing material 17 and the like (not shown) are heated. Since heat moves simultaneously through the two heat transfer routes, the heat of the hot water 43 can be more efficiently transferred to the upper floor finish 17 and the like.

Here, when the hot water 43 is caused to flow through the pipe 19, the pipe 19 is thermally expanded. That is, the outer diameter of the pipe 19 increases in the recess 35. For this reason, the contact area between the pipe 19 and the heat transfer member 27 at the heat transfer member contact portion 39 is increased, and the pipe 19 is more strongly pressed against the heat transfer member 27. Similarly, the contact area between the pipe 19 and the soaking plate 29 at the soaking plate contact portion 41 is also increased, and the pipe 19 is more strongly pressed against the soaking plate 29, so that the thermal resistance is reduced. For this reason, in the state in which the warm water 43 was poured, the heat exchange efficiency is more excellent than the normal state shown in FIG.

In the first heat transfer route described above, at the time of heat conduction in the recess 35 of the heat transfer member 27, the clearance 32 is provided between the outer peripheral surface of the recess 35 and the surface of the pipe groove 31, and the heat conductivity is low. Since it has an air layer, the movement of the heat to the base material 25 can be suppressed. Further, since the clearance 34 is similarly provided in the gap between the rib 37 and the rib groove 33, heat transfer to the base material 25 can be minimized. That is, the heat of the hot water 43 can be efficiently radiated from the heat radiating portion 45 and the downward heat transfer can be suppressed through the base material 25.

Next, the manufacturing method and construction method of the floor heating panel 13 will be described.
4 to 9 are diagrams showing a manufacturing process or a construction process of the floor heating panel 13. First, the base material 25 is prepared. FIG. 4 is a view showing the base material 25, FIG. 4A is a plan view of the base material 25, and FIG. 4B is a front view of the base material 25.

In the base material 25, grooves such as a pipe groove 31 and a rib groove 33 corresponding to an outer shape of a heat transfer member 27 described later are provided in advance. In FIG. 4, as an example, the base material 25 having two rows of pipe grooves 31 and the like is shown in one base material 25, but may be one row or more multiple rows as necessary. A substrate 25 can also be used.

Moreover, as shown in FIG. 5, the base material 47 which has the pipe groove 49 which had the bending shape of the pipe 19 previously can also be used simultaneously. FIG. 5A is a plan view of the base material 47, and FIG. 5B is a front view of the base material 47. In FIG. 5, as an example, a base material 47 on which a pipe groove 49 having a junction branching portion or the like in which two pipe grooves 49 are coupled on an arc or curved in the opposite direction is illustrated. In addition, the pipe groove 49 is not a groove shape in which the heat transfer member 27 can be installed like the base material 25 but a simple pipe-shaped pipe groove. However, in the case of the base material 47 of FIG. 5 as well as the base material 25, the heat transfer member 27 may be provided in accordance with the arrangement of the groove of the bent portion of the base material 47. In this case, the pipe groove 49 is provided. The groove cross-sectional shape may be a groove shape represented by the pipe groove 31 and the rib groove 33 in which the heat transfer member 27 of FIG. In such a case, the groove shape matches the pipe groove shape as shown in FIG.

Next, as shown in FIG. 6, the heat transfer member 27 is installed on the base material 25. 6A is a plan view showing a state in which the heat transfer member 27 is installed on the base material 25, FIG. 6B is a front view of the base material 25, and FIG. 6C is an enlarged view of the heat transfer member 27 portion. FIG. The heat transfer member 27 is installed on the base 25 so that the recess 35 fits into the pipe groove 31 of the base 25 and the rib 37 provided on the lower surface of the flat plate portion 28 fits into the rib groove 33. In FIG. 6, the heat transfer member 27 is installed over the entire length in the longitudinal direction of the base material 25, but the heat transfer member 27 may be divided in the length direction as necessary. A portion where the heat transfer member 27 is not installed may be provided using a heat transfer member 27 shorter than the base material 25.

Next, as shown in FIG. 7, a heat equalizing plate 29 is attached to the upper surfaces of the base material 25 and the heat transfer member 27. FIG. 7A is a perspective view showing a state where the soaking plate 29 provided with the perforation 59 is attached to the base material 25, and FIG. 7B is a view showing that the soaking plate 29 is attached to the base material 25. The perspective view which shows a state, FIG.7 (c) is the E section enlarged view of FIG.7 (b). A perforation 59 is applied in advance to the pipe installation planned portion of the heat equalizing plate 29. When the heat equalizing plate 29 is affixed to the substrate 25, the perforation 59 of the heat equalizing plate 29 is positioned substantially at the upper center of the recess 35. That is, the perforation 59 is an insertion site for the pipe 19 described later. Further, the heat transfer member 27 is fixed to the base material 25 by a heat equalizing plate 29. A member for a floor heating panel in which a heat equalizing plate 29 is attached to the base material 25 on which the heat transfer member 27 is installed is referred to as a panel 30.

FIG. 8 is a plan view showing a state in which the panels 30a, 30b, 30c and the base materials 47a, 47b, 47c, 47d, 47e, 47f are arranged. At the floor heating panel installation site, the panel 30 and the base material 47 are arranged as shown in FIG. A perforation 59 is provided in advance in the pipe installation scheduled portion 48. The pipe installation scheduled portion 48 is, for example, a circuit as indicated by a dotted line in the figure, and can flow the hot water 43 from the F portion and return the hot water 43 from the G portion. In addition, at the floor heating panel installation site, cut the panel 30 etc. or add a cut panel as necessary to change the installation area of the panel to be arranged and adjust the size etc. Can do. Further, the layout of the panel 30 or the like can be reset after the size adjustment, and then the pipe installation scheduled portion 48 can be changed and determined.

Next, as shown in FIG. 9, the pipe 19 is pushed into the recess 35 through the perforation 59, and the pipe 19 is fitted into the heat transfer member 27. 9A is a view showing a state in which the pipe 19 is pressed against the perforation 59, FIG. 9B is a front view showing a state in which the pipe 19 is fitted in the recess 35, and FIG. 9C is a view in FIG. It is the I section enlarged view of (b).

First, the pipe 19 is pressed against the perforation 59 in the H direction in the figure. The perforation 59 of the heat equalizing plate 29 pressed by the pipe 19 is broken by the pipe 19, and the heat equalizing plate 20 near the broken portion is bent into the recess 35 by the pipe 19. As shown in FIG. 9B, when the pipe 19 is completely pushed into the recess 35, the end of the heat equalizing plate 29 (the portion corresponding to the perforation 59) is between the pipe 19 and the heat transfer member 27. It becomes a bent shape. In addition, when pushing the pipe 19 into the recessed part 35, the pipe 19 previously arrange | positioned in the installation part should just be stepped on with a foot | leg.

Here, the pipe outer diameter 55 is larger than the recess inlet width 53. For this reason, when the pipe 19 is pushed into the recess 35, the pipe 19 is inserted into the recess 35 while being slightly elastically deformed, and returns to the original outer diameter when fitted into the recess 35. Therefore, the pipe 19 does not fall out of the recess 35. Further, when the outer diameter of the pipe 19 returns to the original, the pipe 19 is pressed against the soaking plate 29. Furthermore, the soaking plate 29 is also pressed against the pipe 19 by the spring back when it is bent. Therefore, the pipe 19 is in strong contact with the soaking plate 29.

The recess inlet portion width 53 is a width obtained by subtracting the thickness (both sides) of the heat equalizing plate 29 folded into the recess 35 from the width of the narrowest portion of the inlet portion of the recess 35. Further, as shown in FIG. 9C, when the perforation 59 is provided on the heat equalizing plate 29, a burr 57 may occur on the back surface of the heat equalizing plate 29. However, when the pipe 19 is pushed in, the burr 57 is directed to the heat transfer member 27 side which is the opposite direction to the pipe 19. Therefore, the pipe 19 is not damaged by the burr 57.
In addition, for example, at this time, after arranging the pipe 19 at the installation site, it is also possible to affix an aluminum tape or the like coated with an adhesive on one side so as to cover the right and left heat equalizing plates and the pipe of the pipe, If it does in this way, the thermal efficiency of the panel for floor heating will improve further.

Thus, according to the floor heating panel 13 concerning this Embodiment, the floor heating panel which has high heat exchange efficiency can be obtained. Since the pipe 19 can be installed on the base material 25 at the site, the base material 25 and the like can be installed at the site and the most efficient pipe layout can be laid. The layout has a high degree of freedom, and it is not necessary to attach the heat equalizing plate 29 after the pipe 19 is installed on the site. Therefore, the number of work steps can be reduced, and a high quality floor heating panel can be obtained without quality variations due to work variations. Obtainable.

Since the base material 25 can be easily cut or the like before the pipe 19 is installed, the layout of the base material 25 and the like can be changed according to the site. For this reason, it is possible to easily handle installation at the time of renovation where the situation on the site differs from that of the site, such as the conventional factory-assembled unit types and standard products, and the floor shape and large It can cope with construction of area.

If a plastic pipe is used as the pipe 19, the pipe 19 can be installed so as to form one circuit with a single pipe 19 after the layout is determined at the site. It is not necessary to connect pipes by joints, etc., and it has excellent workability and layout design is easy.

The pipe 19 is in contact with both the heat transfer member 27 and the heat equalizing plate 29, and a first heat transfer route for transferring heat to the heat equalizing plate 29 via the heat transfer member 27 and the heat equalizing plate 29 directly from the pipe 19. Since the second heat transfer route through which heat is transferred is provided, heat can be radiated to the upper surface of the floor heating panel with high efficiency.

Further, since the clearance 32 is provided between the outer peripheral surface of the recess 35 and the pipe groove 31 and the clearance 34 is provided between the rib 37 and the rib groove 33, heat from the heat transfer member 27 to the base material 25 is also provided. Therefore, useless heat dissipation to the floor can be suppressed.

Further, since the pipe outer diameter 55 is larger than the recess inlet width 53, the pipe 19 fitted in the recess 35 does not fall out of the recess 35 even if the heat equalizing plate 29 does not exist in the upper part.

Next, the heat dissipation characteristic test result using the floor heating panel according to the present embodiment will be described. FIG. 10 is a diagram showing a heat dissipation characteristic test apparatus 60 used in the test.

The fan 67 flows air in the direction of the heater 65 and controls the temperature inside the protective box 61 to be uniform.

A fan 69 is provided on the side of the panel installation base 75. The fan 69 allows air to flow between the floor heating panel 71 and the protection plate 77. The fan 69 uniformly controls the temperature below the floor heating panel 71.

After installing the floor heating panel 71 to be used for the test, while controlling the interior of the test apparatus to a predetermined temperature, hot water at a predetermined temperature was allowed to flow through the floor heating panel, and temperature measurement was performed at a plurality of locations to evaluate the heat dissipation characteristics. The temperature was measured for the conventional product and the invention product under the test conditions shown in Table 1 using a globe thermometer and a thermocouple. At this time, the inlet temperature of the hot water is 62 ° C., the flow rate (flow velocity) is 1.02 L / min, and the outlet temperature at this time is measured. Was calculated, and the comparison product (floor heating panel 80) and the invention product (floor heating panel 13) were compared.

Based on the above conditions, from the test results, the heat dissipation on the floor of the invention was improved by about 13% compared to the comparative product, and the heat dissipation under the floor was reduced by about 6%. It was confirmed that heat was mainly dissipated on the necessary floor, and unnecessary heat radiation under the floor was suppressed.

That is, according to the floor heating panel 13, the heat can be efficiently recovered from the hot water, and the recovered heat can be efficiently used for heating on the floor without escaping under the floor. Can be obtained.

For example, in the present embodiment, the heat equalizing plate 29 having the perforation 59 is attached. However, a slit or the like may be provided in the pipe installation scheduled portion 48 of the heat equalizing plate 29 after the heat equalizing plate 29 is attached. good. FIG. 11A is a view showing a state in which the soaking plate 29 having no perforation 59 is attached to the substrate 25, and FIG. 11B is a perspective view showing the panel 40 to which the soaking plate 29 is attached. FIG.

The panel 40 does not have a perforation 59 or the like. Therefore, it is necessary to make a cut in the pipe installation scheduled portion of the panel 40 by post-processing. 12 is a view showing a state in which the slits 51 are provided in the panel 40, FIG. 12 (a) is a plan view of the panel 40, and FIG. 12 (b) is a cross-sectional view of the J portion of FIG. 12 (a). The panel 40 can be provided with slits 51 at necessary portions after determining the pipe layout and the like at the site. The slit 51 is provided approximately at the upper center of the recess 35. The slit 51 can be provided by, for example, cutting the heat equalizing plate 29 with a cutter or the like from the upper surface of the substrate 25. According to the panel 40, it is not necessary to make the perforation 59 on the soaking plate 29. Even when the panel 30 is used, if the layout is changed at the site and it is necessary to install the pipe 19 in a portion without the perforation 59, the slit 51 can be similarly provided at the site.

Further, as shown in FIG. 13, the perforations 59 and the slits 51 are not provided by processing the soaking plate 29, but a plurality of soaking plates 29 a, 29 b, 29 c are originally placed directly above the recesses of the heat transfer member 27. , The width direction ends of the soaking plates facing each other may be matched or attached to the substrate 25 so as to leave a very small gap. FIG. 13A is a diagram showing a state in which the soaking plates 29a, 29b, and 29c are attached to the substrate 25 and the like, and FIG. 13B is a panel to which the soaking plates 29a, 29b, and 29c are attached.
