Description

  The present invention relates to an improvement of a hot water type floor chamber apparatus that can efficiently store heat and uniformly heat a floor surface.

  Recently, there are many buildings with floor heaters installed in new buildings. There are two types of heat sources for these floor heaters: hot water heating type and electric heating type. Hot water type devices are more commonly used. ing.

  Hot water heating floor heaters have been used because the floor heating costs are relatively low compared to electric heating systems that use electricity as the heat source because the boiler is heated by burning kerosene and gas. As the soaring oil continues, this merit is becoming suspicious, and there are also essential problems as described below.

  An example of this warm water heating type floor heating apparatus will be described. As shown in FIG. 6B, a thick heat insulating sheet 31 such as urethane foam is laid on a foundation floor 30 such as a concrete layer or a floor base plate, and this heat insulating sheet. A hot water pipe groove 32 is meandered on the upper surface of 31, and a synthetic resin pipe having an inner diameter of about 8 mm to 11 mm or a heat generating pipe 33 made of a metal pipe such as copper or aluminum is fitted in the groove 32. In general, a hot water mat M is formed by piping, and a metal foil 34 such as an aluminum foil is laminated on the hot water mat M, and a floor board (flooring) 35 is disposed thereon. (See Patent Document 1).

In addition, as the electric heating type floor heating apparatus, one using a cable heater (see Patent Document 2) or one using a planar heating element has been proposed (see Patent Document 3).
JP 2006-284053 A Japanese Patent Publication No. 4-81701 Japanese Patent No. 2571595

  A) As described above, the hot water type floor heating apparatus shown in FIG. 6 (B) is often used in which the 8 to 11 mm exothermic pipes 33 are arranged meandering at intervals of about 7 to 10 cm. The area corresponding to the floor plate above the heat generating pipe 33 is a narrow strip portion corresponding to the outer diameter of the pipe 33. Therefore, there is a problem that the heat generation area of the heat generation pipe 33 can be heated only in a striped form within a considerably narrow range as compared with the surface area of the floor to be heated.

As shown by the curve (t ₁ ) in FIG. 6A, the surface temperature of the floor surface when the floor plate 35 is heated only by the heat generating pipe 33 does not exist with the portion where the heat generating pipe 33 exists. Temperature unevenness occurs in the waveform between the part. Therefore, in many cases, a method is adopted in which an aluminum foil 34 is interposed on the heat generating pipe 33 so that the temperature unevenness (t ₁ ) on the floor plate 35 is made uniform such as the temperature (t ₂ ). However, since the heat radiating surface of the heat generating pipe 33 toward the floor plate 35 is linear as described above, it is essentially difficult to make the temperature of the floor surface uniform.

  If the interval between the meandering heat generation pipes 33 is reduced, the heat radiation area toward the floor plate 35 will increase. However, in reality, the heat generation pipe 33 becomes longer, the fluid resistance of hot water increases, and the number of joints increases. As a result, the piping path becomes complicated, and accordingly, leakage of hot water occurs, and the strength for supporting the floor plate 35 is further reduced, so this method cannot be adopted.

B) In addition, a big problem with hot water type floor heating is that hot water heated by the boiler is supplied to the heat generating pipe 33 to dissipate heat, and is then recirculated to the boiler. Inevitably, there is a temperature difference. The length of the hot water pipe 33 is laid in units of 12 m per 1 m ² , and the length of the hot water path extends over a considerable distance.

  Therefore, a system in which hot water of about 80 ° C. is supplied from one side of the room to the heat generation pipe 33, heat is dissipated while meandering under the floor board, and the floor surface is heated, and then the temperature is lowered to about room temperature and returned to the boiler Therefore, naturally, a large temperature difference must be generated between the supply unit and the reflux discharge unit.

  C) On the other hand, most building materials are treated with chemicals such as preservatives (formaldehyde, etc.), and heating the flooring that has been treated with this chemical will adversely affect the human body such as benzene, xylene, and toluene. Gas is generated. This gas has a problem of causing “sick house syndrome” that is suddenly released at a temperature of 44 ° C. or more and pollutes indoor air, and preventing it is also a problem of the floor heating apparatus.

  D) A planar heater that is manufactured using a thermoplastic resin as an electrothermal heater (has an electrical resistance that increases with increasing temperature and suppresses the amount of current to automatically decrease the temperature). Since the exothermic temperature is as low as about 50 ° C., usually 40 ° C. or less, the sick house syndrome can be avoided, and since the heat radiation surface is wide, the floor surface can be heated all at once to a predetermined temperature. There is an advantage that you can.

  Most of the electric heating type uses a planar heater, but this is about 35% to 60% of the floor area of the room to be heated. There is an advantage that it can be heated at a uniform temperature.

  Compared with the temperature of the floor heating device using the planar heater and the temperature of the hot water heating type floor heating device, the former temperature is about 40 ° C., whereas the latter temperature is as large as 80 ° C. to 30 ° C. A temperature difference is inevitably generated, and the latter must be considerably higher than the former.

  E) In particular, the influence on the flooring at the entrance where hot water as high as 80 ° C is supplied from the boiler is large, and the difference in thermal expansion and contraction of the floorboards is large due to the large temperature difference between when the floor is heated When this temperature difference is repeated, gaps are gradually formed between the floorboards, which causes the floorboards to float and cause squealing, and causes a sense of incongruity that is not stable and fluffy when the weight is applied to the floorboards. It has become. In other words, wood grown in nature is not suitable for high-temperature heating and causes deformation and deterioration of the plate material. Therefore, it is preferable to heat at a low temperature in order to avoid the influence on the wood.

  F) In Patent Document 1, a hot water pipe is arranged in the groove formed in the heat insulating layer, an aluminum plate is arranged on the upper part of the “hot water mat”, and a heat transfer plate with fins protruding on the upper surface thereof. A structure is adopted in which the generated heat is spread over the entire lower surface of the floor plate via the heat transfer plate.

  However, the heat transfer plate having the above-described structure requires a complicated cross-sectional shape, and further, slits matched to the fins must be formed on the floor plate, which causes a considerable problem in workability. Further, such a processing method is unavoidable to weaken the strength of the floor board itself, and a new defect is generated in the floor structure by adopting this structure, which is a practical problem.

G) Objects of the present invention The present invention provides (a) a hot water heating apparatus that solves the problem of temperature unevenness, which is a drawback of the hot water heating heating apparatus, and can be heated at a uniform temperature. This is the first purpose.
(B) And by keeping the hot water to be supplied as low as possible and supplying it to the heat generation pipe, the hot water heating type floor heating which does not affect the wood to the floor board by high temperature heating to the floor board is provided. A second object is to provide an apparatus.
(C) Furthermore, a composite floor heating apparatus that takes advantage of the heat storage and heat transfer of a heat storage heat member using a latent heat type heat storage agent and a metal foil honeycomb, and eliminates the disadvantages of the hot water heating floor heating apparatus. It is the third purpose to provide.
(D) Furthermore, heat is stored in a space between the hot water pipes arranged at a predetermined interval by a heat storage agent, and the temperature unevenness is eliminated by dissipating the heat during heating. It is a fourth object of the present invention to provide a heat storage member that can efficiently absorb and dissipate heat from the heat storage agent and mechanically support the flooring.

  In order to achieve the above object, the present invention is configured as follows.

  1) In a heat insulating sheet laid on a base floor material and a floor heating apparatus arranged with a space between hot water pipes on the heat insulating sheet, a latent heat storage type heat storage agent is placed in a space between the hot water pipes. The heat storage member filled with is arranged, and the heat dissipation from the hot water pipe is stored in the heat storage member.

  2) The heat storage member is composed of a bag body made of a heat-resistant electric insulating sheet, a honeycomb-type heat conductor and a latent heat-type heat storage agent housed therein.

  3) The honeycomb-type heat conductor is a honeycomb structure made of metal foil having an opening in the thickness direction of the heat storage member.

  4) In a floor heating device comprising a heat insulating sheet laid on a foundation floor material and a hot water pipe disposed at a predetermined interval on the heat insulating sheet, a heat storage member is disposed between the hot water pipes, The hot water pipe and the heat storage member are covered with a metal foil, and a floor board is further laid on the upper surface. The position where the metal foil is arranged is more suitable on the hot water pipe, but it may be on the lower surface or both upper and lower surfaces. In short, the heat generated by the hot water pipe may be configured to spread over the entire floor surface.

  5) In a floor heating apparatus comprising a heat insulating sheet laid on a base floor material and a hot water pipe meandering on the heat insulating sheet at a predetermined interval, a heat storage member is disposed between the hot water pipes. In addition, the heat storage member accommodates a bag body made of a sheet having heat resistance and electrical insulation, and a honeycomb type heat conductor made of aluminum foil so as to directly support the inner surface of the bag body, and further the bag The body is filled with a latent heat-type heat storage agent, and the heat storage agent is divided into a plurality of small blocks by the honeycomb-type heat conductor to the latent heat-type heat storage agent through the wall surface formed of the honeycomb-type heat conductor. It is characterized by giving and receiving heat.

1) The warm water heating type floor heating apparatus according to the present invention has a structure in which a heat storage member is disposed between a warm water pipe and the warm water pipe, and a floor board is disposed thereon. The heat storage member accommodates the honeycomb type heat conductor in the bag body and is filled with a latent heat type heat storage agent, and the heat storage agent is divided by the honeycomb type heat conductor to absorb heat and release heat in a small section. Although it is a thin plate type heat storage member, it conducts heat well on the front and back surfaces and guides the heat from the heat generating pipes arranged on both sides to the inside of this heat storage member to exert the heat storage effect be able to.
As a result, while adopting a conventional hot water heating type floor heating device, the entire portion where the floor heating device is arranged can sufficiently store the required amount of heat and exhibit its effect at low temperatures. It can be done.

  2) The floor heating apparatus according to the present invention can produce hot water using cheap nighttime electric power by using a latent heat type heat storage member. By circulating hot water, this hot water pipe can be regarded as a part of a kind of boiler, and its configuration can significantly reduce heating costs and store heat in the floor structure. The “capacity” of the boiler itself can be reduced, and the water heater can be downsized.

  3) In the case of the conventional floor heating device, hot water is required, and as a result, sick house syndrome is generated or the floor board is distorted. It can be solved.

(About the function of the heat storage member)
Since the composite type floor heating apparatus according to the present invention uses a heat storage member filled with a latent heat storage type heat storage agent as an important constituent member, the heat storage characteristics of the heat storage member will be described.

1. Basic data of various types of heat storage member FIGS. 7 to 10 show the form of a container filled with a heat storage agent to form a heat storage member, and the surface area in contact with the heat storage agent is significantly different depending on the difference in these forms. In addition, it will be explained that the state of heat transfer by dividing the heat storage agent into small sections is significantly different.

1) Surface area for transferring heat (cm ² ) / liter (type 1): 1,113 (type 2): 1,540 (type 3): 3,540
(Type 4): 9,735
(Evaluation) Assuming that the surface area of type 1 is “1” as a reference, type 2 is (1.4), type 3 is (3.2), and type 4 is (8.7).
In other words, by using a honeycomb-type heat transfer body (4 type), the surface area is expanded (8.7 times) to 1 type (lunch box type), and 2 types (cylindrical parallel type, heat bank type). ), The surface area is expanded by (6.3) times.
Further, when considering the aggregate state of the latent heat type heat storage agent, the type 1 forms one lump in the box, and the volume of the heat storage agent is 3,000 cc in one lump state.
Type 2 is 640 cc, and type 3 is 230 cc as one lump. On the other hand, in the case of the 4 type honeycomb of the present invention, one cell is only an aggregate of hexagonal frame bodies with one cell having an ultra-small size of about “0.2 cc” and the top and bottom missing.
Therefore, comparing the size of type 4 (FIG. 10) and type 1 (FIG. 7), the volume of one cell is only 1 / 5,000 of that of type 1.
Further, when the cells of the 2 type (FIG. 8) and 4 type honeycombs are compared, it is 1/200, and when the 3 type (FIG. 9) heat storage mat is compared, the volume is 1150 minutes. 1 and the honeycomb structure described in FIG. 10 can be well understood how to divide the heat storage agent into a minute volume.

(Specific configuration of hot water floor heater)
Example 1
FIG. 1 shows the position of the cross-sectional structure of the hot water floor heater (Y) of the present invention. In the case of corresponding to the conventional example shown in FIG. 6, a small joist 20 is arranged on a large pull 19 supported on a bundle (tsuka) 18 standing upward such as a concrete layer. A plate material 21 is disposed between them.

  Then, a heat insulating sheet 22 such as expanded polystyrene is disposed on the upper surface of the plate member 21, a heat transfer sheet such as an aluminum foil 23 is further laid thereon, and the heat generating pipes 33 a. This aluminum foil also has a structure laid on the upper surface of the hot water pipe 33 and the following heat storage member 1. The floor board 35 is laid on it. This structure corresponds to the structure of the conventional hot water type floor heating apparatus shown in FIG.

  The entire configuration of the floor heating device (Y) is shown in FIG. 11, and hot water pipes 33 and heat storage members 1 are alternately arranged between a plurality of small joists 20 arranged on the floor surface of the room R. Yes. The hot water pipe 33 schematically has a karate picture, but is actually formed by following the conventional construction method.

  In the hot water heating type floor heating device (Y) of the present invention, as shown in FIG. 1, the heat storage member 1 formed in a special structure described later is disposed between the heat generating pipes 33a, 33b,. An area between the two is defined as a “heat storage region”, and heat absorption and heat dissipation are performed in this region.

  As shown in FIGS. 2 and 3, the heat storage member 1 is made of an aluminum foil or the like inside a bag 2 formed using a synthetic resin sheet having heat resistance and electrical insulation, such as polyethylene, polypropylene, and nylon. A honeycomb-type heat conductor 3 formed using a metal foil is disposed to constitute a “full-surface heat radiation type” floor heating apparatus.

  The honeycomb-type heat conductor 3 is an aggregate of hexagonal metal foils and is a structure in which both surfaces are opened. By inserting the heat conductor 3 inside the bag body 2, it has a function of supporting a predetermined form by supporting it in the state of a thin plate, and at the same time, the following latent heat type latent heat type heat storage It has a function of dividing the agent 4 into small compartments.

  The wall surface formed in the honeycomb type (hexagonal shape) with respect to the heat storage agent 4 divided in this way divides the heat storage agent 4 into small sections, and the heat energy received from the heat receiving surface through the wide wall surface. Has a function of transferring heat to the heat storage agent 4.

  Furthermore, since a large number of thin plates are assembled in a honeycomb shape, they have excellent mechanical properties, that is, pressure resistance, and have the property of reinforcing the floor structure using this property. The floor plate 35 can be reliably supported from the lower surface, thereby having a function of preventing defects such as floor noise and bending.

  The thickness of the aluminum foil used for the honeycomb-type heat conductor 3 in FIG. 10 is 50 μm to 100 μm, and the width of the cells constituting the honeycomb (distance of facing wall surfaces) is 5 to 8 mm, preferably 6.35 mm Is used.

  The honeycomb-type heat conductor 3 has a thickness (height) of about 5 mm to 10 mm, preferably 1/3 inch. Various sizes of cells constituting the honeycomb plate can be used. As described above, for example, a cell having a space between walls (a space c shown in FIG. 10B) of 6.35 mm should be used. Thus, an inexpensive honeycomb structure can be used.

  Further, a latent heat type heat storage agent 4 (see Japanese Patent No. 3390238) is supplied into the bag body 2 and the inside of the honeycomb type heat conductor 3 is filled with the latent heat type heat storage agent 4.

  Depending on the type of the heat storage agent 4, there may be a chemical reaction with the aluminum foil constituting the aluminum honeycomb to deteriorate it. Therefore, surface treatment for preventing such deterioration in advance, that is, a corrosion-resistant synthetic resin. It is better to carry out protective processing such as application of paint and anodizing.

(Function of honeycomb-type heat conductor 3)
The function of the honeycomb-type heat conductor 3 is as described above, and as shown in FIG. 5, a) the action of dividing the heat storage agent 4 into small sections, b) the amount of heat Q received by the heat receiving surface S2 of the heat storage member 1 That quickly transfers heat to the heat radiating surface S1 side, c) the heat storage agent 4 is divided into small blocks (FIG. 10, B), and the heat transfer is increased in a wide area formed inside and outside the wall surface. (FIG. 5), d) Various excellent things, such as the effect | action which reinforces the thermal storage member 1 (FIG. 2, FIG. 3) and gives the pressure resistance as a flooring.

  Further, the latent heat type heat storage agent 4 is divided by dividing the inside of the bag body 2 by the honeycomb type heat conductor 3, preferably into predetermined small sections, and the “supercooling phenomenon” of the heat storage agent 4 is divided. Configure to prevent.

  The supercooling phenomenon means that while repeating a reversible phase change from solid to liquid and from liquid to solid, its properties cannot be lost and it cannot return to liquid state, and it remains a fairly hard solid. The remaining part occurs. When this solidification phenomenon occurs, this phenomenon gradually propagates to other parts, and finally, the heat storage agent for one bag maintains a solid state.

  In this state, the function as a latent heat type heat storage agent is no longer lost. Therefore, conventionally, a method of adding and mixing a supercooling inhibitor (crystal nucleus substance) to a heat storage agent has been implemented (see, for example, JP-A-7-42961).

As this latent heat type heat storage agent 4, any material that has been conventionally used as a heat storage agent for floor heating devices can be used. In other words, it is better to use a heat storage agent of a type that receives heat and becomes liquid, dissipates heat, changes to a solid layer, and stores a large amount of latent heat during its phase change. Sodium sulfate · 10 hydrate (Na ₂ SO ₄ · 10H ₂ O) or the like can be used.

  This sodium sulfate decahydrate has a melting point of 31.8 ° C. and a freezing point of 28 ° C. The latent heat during this phase change has the property of storing and releasing heat of 155 kJ / kg. is doing. Therefore, even when heated to a high temperature, the temperature is about 50 ° C., and the function of floor heating can be fully exhibited even when heat radiation is solidified.

(Honeycomb type heat conductor 3 is a heat conductive polygonal wall)
The combination of the honeycomb-type heat conductor 3 and the latent heat storage agent 4 exhibits a very large effect as the heat storage member 1 for floor heating of the present invention. For example, the heat conduction efficiency of an aluminum foil having a thickness of 0.1 mm and a polypropylene film having a thickness of 1.0 mm are compared as follows.

  The thermal conductivity (W / (m · k)) is (23.7) for aluminum, whereas (0.3) for polypropylene, and considering the thickness of both, aluminum is polypropylene. "23.7 times" is superior in thermal conductivity. Therefore, if both have the same thickness, this thermal conductivity will have a larger difference.

  By making the aluminum foil (same for other metal foils) into a honeycomb structure, the cells (small chambers) of this honeycomb structure are filled with the latent heat storage agent. As compared with the case where the heat storage agent is simply filled in the thin plate-shaped bag (FIG. 7), the contact area is expanded to “about 8.74 times”.

  As described above, the thermal conductivity between the aluminum foil and the polypropylene is 23.7 times, and further considering the difference of 8.74 times in the contact area of the honeycomb structure, it is about 740 compared with a simple bag body. It has twice as much “heat conduction efficiency”.

  In the present invention, a heat storage member 1 is configured by combining a honeycomb type heat conductor made of metal foil, preferably aluminum foil, and a latent heat type heat storage agent. Therefore, three-dimensional heat transfer is performed by disposing the honeycomb heat conductor 3 in the layer of the latent heat type heat storage agent 4.

FIG. 5 shows a heat storage member in which sheets S ₁ (heat radiation surface) and S ₂ (heat absorption surface, heat reception surface) constituting the bag body 2 are arranged on both surfaces of the honeycomb structure H constituting the honeycomb type heat conductor 3. FIG.

In FIG. 5, when the heat quantity Q is given from the sheet S ₂ side constituting the bag body 2, the heat quantity Q is in a three-dimensional state like a heat radiating fin in the honeycomb structure H, and heat is transferred in all directions. Since heat is quickly transferred to the latent heat type heat storage agent 4 in contact with the honeycomb structure H, heat transfer to the heat storage agent can be performed quickly, and Such a supercooling phenomenon can be completely prevented.

On the other hand, when a honeycomb structure having a hexagonal circumference of 2.07 cm and a height of 1/3 inch is considered, the number of honeycomb structures (cells) per square meter is about 31,000. . The contact area between the honeycomb structure and the latent heat storage agent, a plate made of a honeycomb structure per 1 m ^2, a large area 1.1 m ² things.

  In this way, the layer composed of the latent heat type heat storage agent 4 is divided by the honeycomb structure 3 means that the heat storage agent 4 is subjected to heat transfer independently to change the phase of the heat storage agent 4. is doing.

  Therefore, even if the heat storage member 1 incorporating the thin plate-like honeycomb structure 3 of about 5 to 10 mm as described above is used, it means that the heat storage effect as a sufficient latent heat type heat storage agent is exhibited. .

(Example 2)
FIG. 4 shows a sectional view of a floor heating device (Y ₂ ) showing another embodiment. In this example, a bag body 2a is used as a heat storage member 1a, for example, a child having a width of 6 cm and a length of 10 cm. In the figure, a bag is divided and a honeycomb heat conductor 3a is arranged in the bag body 2a and the latent heat storage agent 4 is filled.

  The feature of this embodiment is that the structure of the conventional hot water type floor heating device is left as it is, and the thin sheet type heat storage member 1a applied in the present invention is laid, and the height of the floor plate 35 is the heat storage member 1a. However, there is no major problem in practical use.

(Example 3)
FIG. 11 is a plan view showing a state in which the hot water heating type floor heating apparatus (Y) shown in FIG. 1 is configured between the small joists 20 that are the floor structure of the room R to be floor heated. The hot water pipe 33 is meandering between the hot water pipes 33, and the heat storage member 1 is arranged in a striped pattern between the hot water pipes 33. The heat storage member 1 has both sides sandwiched between heat generation pipes 33. Heat is transmitted to the heat storage member 1 through the hot water pipe 33 to be stored, and when the heat is dissipated, the heat is released from the entire floor surface for heating. . Since this heat radiation is performed not only from the hot water pipe 33 but also from the heat storage member 1, the supplied hot water can exhibit a heating effect sufficiently while the temperature is low.

  The heat storage member 1 has a width that can be fitted between the hot water pipes 33 and is divided by welding at intervals of 10 to 20 cm in the longitudinal direction, and the honeycomb type heat transfer body 3 and the inside of each bag. It goes without saying that the latent heat storage agent 4 is accommodated.
