Description

Heating system using ondol panel {HEATING SYSTEM USING HEATING PANEL}

The present invention relates to a heating system using an ondol panel, and more particularly, an ondol panel having a fluid flow space between upper and lower plates to perform heating through a flow of heating fluid, and a heating system using the ondol panel. It is about.

In general, as a heating system of a home building, a pipe is laid on a concrete floor and a heating structure such as hot water is supplied to the pipe to perform heating, but recently, a plate-type ondol panel having a fluid flow space therein is provided. It is expected to be developed and applied to a prefabricated heating system.

Compared to the pipe structure, the ondol panel method is easier to construct and repair, and there is no heat loss due to concrete, thereby improving heating efficiency. In connection with such an ondol panel structure, U. S. Patent No. 5,080, 166 discloses a plate-shaped heating element.

The prior patents particularly present a number of spacing elements provided between the upper and lower plates constituting the heating member to distribute the fluid supplied to the heating member evenly, and the preferred arrangement of the space members. .

However, as a result of the applicant's simulation, the space member induces a flow of the heating fluid in a specific direction, so that the heating fluid has a non-uniform distribution inside the heating member. It is assumed that this is because they are connected in a specific direction.

Furthermore, the heating element has a fluid connection portion where fluid is supplied and discharged at two corner portions facing each other in the diagonal direction of the heating element, and the heating element has two other corner portions without the fluid connection portion. The flow rate of the heating fluid tends to decrease.

Therefore, the heating fluid is stagnated at the corners of the heating fluid, thereby lowering the corner temperature, or air bubbles are generated inside the heating member due to the turbulent flow of the corners, thereby inhibiting the smooth flow of the heating fluid. As a result, the conventional heating member has a disadvantage that the ondol distribution is not constant and the heating efficiency is lowered due to the stagnation of the heating fluid.

Therefore, the present invention is to solve the above problems, an object of the present invention is to provide an ondol panel to distribute the flow of the heating fluid supplied to the ondol panel more evenly distributed inside the ondol panel.

Another object of the present invention is to provide an ondol panel that eliminates stagnation and bubble generation of a heating fluid generated at a corner by raising a flow rate of a heating fluid flowing through another corner of an ondol panel having no fluid connection.

It is still another object of the present invention to provide a heating system that allows a heating fluid to continuously travel inside a plurality of ondol panels using a connection structure connecting a plurality of ondol panels and a cavity of the ondol panel.

A connecting member for allowing fluid to continuously travel inside the plurality of ondol panels, the space members being in a first direction parallel to either side of the upper and lower plates and parallel to the other side of the upper and lower plates. The first, facing the fluid connection, arranged continuously along a second direction to provide a continuous cavity in the first and second directions Provided is a heating system using an ondol panel comprising at least one dispersing member positioned at a point on a continuous cavity in two directions to disperse the flow of heating fluid.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an assembled plan view of a heating system according to an embodiment of the present invention, and FIG. 2 is an enlarged view of the connection member shown in FIG. 1, wherein the heating system has an inner space, ie, a cavity (not shown), through which heating fluid flows. A plurality of ondol panels 2 and a plurality of connecting members 4 which integrally connect the plurality of ondol panels 2 to provide a fluid path between the ondol panels 2 are included.

Here, each of the ondol panel 2 is made of thermoplastic plastic, which is easier to manufacture and form than the metal pipe structure, and is formed in a plate shape so that the heating fluid traveling through the inside of the ondol panel 2 covers a larger area. Make sure you are touching the floor (or wall or ceiling).

In the present embodiment, the ondol panel 2 has, for example, a rectangular structure having a pair of long sides and short sides, and each of the ondol panels 2 has a heating fluid at two corners facing each other in a diagonal direction. Two fluid connections 6 are provided for supplying and discharging.

And each of the ondol panels 2 are arranged in series so that any one of the fluid connections 6 faces the fluid connections 6 of the adjacent ondol panels 2, and two fluid connections between the respective ondol panels 2. The connection member 4 which engages (6) is provided.

As shown in FIG. 2, the connecting member 4 is composed of a connecting pipe 8 at the center and a pair of elbows 10 assembled at both ends of the connecting pipe 8, and the inner diameter of the elbow 10 is increased. It is made larger than the outer diameter of the fluid connection portion 6 so that the elbow 10 is fitted to the outer peripheral surface of the fluid connection portion (6).

In addition, the elbow 10 is made of the same thermoplastic plastic as the ondol panel 2, and when the heating system is assembled, the elbow 10 is integrally assembled to the ondol panel 2 by a heat fusion process while surrounding the fluid connection 6. Be sure to

Thus, the heating fluid provided to the inlet of the heating system is discharged by the connecting member 4 in turn through the inside of the plurality of ondol panels 2 to the outlet of the heating system, and the flow direction of the heating fluid is indicated by the dotted arrows in the figure.

In such a prefabricated heating system, each of the ondol panels 2 allows the ondol panels to flow smoothly so that the heating fluid does not concentrate or stagnate in a specific portion of the ondol panel 2 in consideration of the thermal efficiency of the heating system. It is very important to keep the temperature distribution of (2) uniform.

3 is a perspective view of an ondol panel according to a first embodiment of the present invention, FIG. 4 is a partially enlarged view of FIG. 3 for explaining the space member, and FIG. 5 is a line AA of FIG. 3 for explaining the inside of the ondol panel. It is a cross section.

As shown, the ondol panel 2 is provided with the upper and lower plates 14 and 16 facing each other with the internal cavity 12 and toward the other plate in the respective upper and lower plates 14 and 16. It includes a plurality of space member 18 extending at intervals of the diameter of the upper and lower plates 14 and 16, and a pair of fluid connecting portion 6 for supplying and discharging heating fluid.

The space member 18 prevents deformation of the upper and lower plates 14 and 16 by external force, and provides a cavity 12 through which a heating fluid flows between the plurality of space members 18. As a result, the heating fluid supplied to either of the fluid connections 6 flows out of the upper plate 14 as shown by the dotted arrows in FIG. 5 while flowing through the cavity 12 between the upper and lower plates 14 and 16. Will be delivered.

The space member 18 also resists the flow of the heating fluid so that the heating fluid is evenly distributed within the ondol panel 2, whereby the flow of the heating fluid supplied to the ondol panel 2 is reduced to that of the space member 18. It is greatly affected by the diameter, spacing, and arrangement.

In this embodiment, the space member 18 is formed in a circular shape having a predetermined diameter, these space member 18 is a horizontal axis (x-axis in the figure) parallel to the long side of the ondol panel 2, and the ondol panel ( It has a regularity arranged side by side along the vertical axis (y-axis in the figure) parallel to the short side of 2). Preferably, the spacings D1 and D2 between the space members 18 facing in the horizontal axis and vertical axis directions are equal to the diameter D of each space member 18.

In addition, the fluid connection portion 6 through which the supply and discharge of the heating fluid is performed, for example, has a central axis (z-axis in FIGS. 6 and 7) above and about 45 ° with respect to either side of the lower plates 14 and 16. It is provided to have. As a result, the heating fluid supplied through any one of the fluid connecting portions 6 is distributed by the plurality of space members 18 facing the flow of the heating fluid, so that the flow flows through the inside of the ondol panel 2.

In particular, the present embodiment forms a dispersing member for dispersing the fluid flow facing each fluid connection 6 to which the heating fluid is supplied or discharged. FIG. 6 is a partially enlarged view of the ondol panel for explaining the dispersing member, and FIG. 7 is a schematic view showing a distribution state of the heating fluid. For convenience, the space member 18 and the dispersing member ( 20 and 22 are shown by hatching.

As shown, the plurality of space members 18 are arranged side by side at regular intervals along the horizontal and vertical axis directions of the ondol panel 2, so that the inner cavity 12 through which the heating fluid flows also faces the fluid connection 6 It is set continuously in the horizontal and vertical directions.

At this time, the ondol panel 2 forms the first dispersion member 20 at one point on the cavity (center position indicated by the virtual D line) continuously set in the horizontal axis direction facing the fluid connecting portion 6, and the fluid A second dispersing member 22 is formed at a point on the cavity (center position indicated by an imaginary E line) continuously set in the vertical axis direction opposite to the connecting portion 6.

As a result, the first dispersion member 20 does not coincide with other space members 18 along the horizontal axis direction of the ondol panel 2, and the second dispersion member 22 is also in the vertical axis direction of the ondol panel 2. Along the other side, it has an arrangement structure in which the center position does not coincide with the other space members 18. In other words, the first and second dispersion members 20 and 22 are not positioned in line with the other space members 18 along the horizontal axis and vertical axis directions of the ondol panel 2.

Thus, the first and second dispersion members 20 and 22 block the continuous cavities 2 corresponding to the imaginary D lines and the E lines from being directly connected to the fluid connection 6 so that the heating fluid is prevented from these continuous cavities 12. Disperse the concentration.

In more detail, the space members 18 are continuously arranged along the horizontal axis and the vertical axis direction of the ondol panel 2, and are continuously arranged along the central axis (z-axis in the figure) of the fluid connection part 6, Assuming that a space member closest to the fluid connection portion 6 among the plurality of space members 18 arranged along the central axis of the fluid connection portion 6 is the first space member 24, the first and second dispersion members 20 , 22 is provided at a position where the heating fluid is supplied and the flow is separated by the first space member 24.

That is, the first dispersion member 20 is located at a point on the first continuous cavity, that is, the first virtual line (indicated by a dashed line in the drawing), in which the fluid flow hitting the first space member 24 is separated in the horizontal axis direction. The second dispersing member 22 is located at a point on the first continuous cavity, ie the second virtual line (indicated by the E-dashed line in the drawing), in which the fluid flow striking the first space member 24 is separated in the vertical axis direction. .

In particular, referring to the positional relationship between the first space member 24 and the first and second dispersion members 20 and 22 with reference to FIG. 6, a tangent connecting the first space member 24 and the first dispersion member 20 to each other is described. (Indicated by a dotted line B in the drawing) is parallel to the horizontal axis of the ondol panel 2, and a tangent connecting the first space member 24 and the second dispersion member 22 (indicated by the dotted line C in the drawing) is the ondol panel. Parallel to the vertical axis of (2), it can be seen that these two tangent lines intersect each other perpendicularly with the first space member 24 as a vertex.

With the above-described configuration, as shown in FIG. 7, the heating fluid provided inside the ondol panel 2 along the central axis (z-axis in the figure) of the fluid connecting portion 6 is firstly applied to the first space member 24. By hitting, the flow is separated in the horizontal axis and vertical axis directions of the ondol panel 2.

In addition, the fluid flow separated in the horizontal axis direction is separated again in the vertical direction by the first dispersion member 20 so that the fluid flow in the horizontal axis direction is dispersed, and the fluid flow separated in the vertical axis direction is transferred to the second dispersion member 22. This separates in the left and right direction again to distribute the fluid flow in the vertical axis direction.

In addition, the fluid flow dispersed by the first and second dispersion members 20 and 22 is separated again by the plurality of space members 18 set continuously along the horizontal and vertical axis directions of the ondol panel 2.

Therefore, in the ondol panel 2 having the above-described internal structure, the flow of the heating fluid separated through the first space member 24 allows the first and second dispersion members 20 and 22 to have the horizontal axis and the vertical axis of the ondol panel 2. In the direction of distribution to distribute the heating fluid provided to the fluid connection 6 more evenly into the ondol panel 2.

On the other hand, the ondol panel 2 is arranged to face the fluid connecting portion 6, the first and second dispersing members 20, 22 and the guide channel in the other two corners where the fluid connecting portion 6 is not located It can be provided.

FIG. 8 is a plan view of an ondol panel according to a second embodiment of the present invention, and FIG. 9 is a partially enlarged view of FIG. 8 for explaining a guide channel, in which the ondol panel 2 is not provided with a fluid connection 6. The first and second guide channels 26 and 28 are formed by replacing the space member 18 at the other two corner portions.

The first and second guide channels 26 and 28 extend vertically from the upper and lower plates 14 and 16 to the other plate in the same manner as the space member 18, so that the upper and lower plates 14 and 16 are vertical. It is formed to have a predetermined width and length along the horizontal axis (x-axis in the drawing) and the vertical axis (y-axis in the drawing) direction of the ondol panel 2 at regular intervals from the edge of the ondol panel (2).

Preferably, the width W of the first and second guide channels 26 and 28 is the same as the diameter D of the space member 18, and the first and second along the horizontal and vertical axis directions of the ondol panel 2. The length of the guide channels 26 and 28 is about 6 to 10 times the diameter D of the space member 18 so that the length of the guide channels 26 and 28 is the same as that of three to five space members 18 integrally connected.

The first and second guide channels 26 and 28 reduce the resistance of the heating fluid at the corners of the ondol panel 2 to increase the flow rate of the heating fluid, and guide the flow of the heating fluid in the direction in which the heating fluid is discharged. It plays a role. Accordingly, the ondol panel 2 having the first and second guide channels 26 and 28 suppresses stagnation of heating fluid or generation of bubbles due to turbulent flow at the corners, thereby uniformizing the temperature distribution throughout the ondol panel 2. .

On the other hand, the preferable aspect ratio (ratio of long side: short side of the ondol panel) in consideration of the flow of the heating fluid in the rectangular ondol panel 2 is preferably in the range of 1.5: 1 to 3: 1.

In consideration of the symmetry of the connecting member 4, the central axis of the fluid connecting portion 6 is set at an angle of 45 ° with respect to the long and short sides of the ondol panel 2, and the ondol panel 2 has a square structure. This is because the heating fluid concentrates the flow in the diagonal direction connecting the two fluid connecting portions 6, making it difficult to uniformly distribute the flow of the heating fluid inside the ondol panel 2.

In addition, the ondol panel 2 may have a polygonal structure such as hexagonal or octagonal structure as shown in FIGS. 10 and 11 in addition to the above-described rectangular structure, in which case the continuous heating of the ondol panel 2 during construction of the heating system It is possible to make the arrangement easier.

On the other hand, the ondol panel 2 minimizes the heat loss of the ondol panel 2 and compensates for the height difference of the fluid connecting portion 6 with respect to the upper and lower plates 14 and 16, so that the construction of the building floor is better. 12, it is preferable to form a heat insulation layer 30, more specifically a styrofoam layer, on the bottom surface of the lower plate 16.

In the above description of the preferred embodiment of the present invention, the present invention is not limited to this, but can be carried out in various ways within the scope of the utility model registration claim and the detailed description of the invention and the scope of the accompanying drawings. Naturally, it belongs to the scope of the present invention.

As such, the present invention includes a plurality of space members, a dispersion member, and guide channels in the ondol panel to more evenly distribute the heating fluid supplied to the ondol panel, thereby uniformizing the temperature distribution of the ondol panel, and heating the entire ondol panel including the corner part. Improves heat transfer efficiency by allowing fluid to run more smoothly.
