Description

Hot water heating floor panel and method of calculating mortar finishing height}

The present invention relates to an ondol panel that is installed on the floor of a residential area such as a house or an apartment and heated by hot water. More specifically, the mortar of a hot water ondol panel and a hot water ondol panel that removes noise between floors in an apartment-type residential environment and reinforces the heat storage function. How to find the height of the plasterer.

Ondol is a traditional heating method in Korean houses, which warms the floor first from the heat source and heats the living space by the indirect radiant heat of the heated floor, so the warmth lasts for a long time even after the heat source is removed. In addition, the Western fireplace heating method can heat the surroundings quickly by directly using the heat generated from the heat source, but immediately loses warmth when the heat source is removed.

Ondol fuel is mainly straw, wood, and charcoal, and it reduces the poisoning effect of carbon monoxide gas generated by using coal as fuel in modern times, and uses various kinds of energy such as oil, gas, and electricity. In order to increase the hot water boiler using hot water was developed, it is common to use such hot water as the heat source of the ondol, and the ondol using hot water is called hot water ondol.

In particular, the residential space in the modern society is composed of multi-level apartment-type residential spaces, such as apartments and multi-generational units, and the floor of the upper floor is the ceiling of the lower floor. The impact sound from the back of the tree is transmitted to the lower floor as it is, resulting in serious interlayer noise.

And these apartment-type residential space mainly uses the hot water ondol method using the hot water heated by the boiler for traditional Korean ondol heating.

In addition, since the ondol device warms a wide bottom surface, it is necessary to install a heat insulator on the bottom surface and prevent heat leakage so that it does not leak unnecessaryly through the ground or the lower part which does not utilize heat. In addition, the heat generated by the heat source is supplied as much as possible to the upper surface of the living space without loss, and the change of temperature does not occur suddenly, and it changes linearly, and at the same time, the heat is stored so that even if the supply of the heat source is stopped for a long time It is necessary to allow fever to last for a while.

In addition, it is necessary to determine the appropriate plaster height (thickness) of the mortar so that it is hot in one part of the ondol and not hot in the other part, and generates heat uniformly throughout the floor.

In the present invention, hot water ondol warming the ondol using hot water, in particular, in the apartment-type residential space to eliminate the noise between floors and accumulate the heat generated during the heating process to maintain the warmth for a long time even after the heat source is removed at the same time the total amount of heat It relates to a technique for determining the plaster height of mortar to occur uniformly.

The terms or words used in this specification and claims are not to be construed as limiting in their usual or dictionary meanings, and the inventors may properly define the concept of terms in order to best explain their invention in the best way possible. It should be interpreted as meaning and concept corresponding to the technical idea of the present invention. Detailed descriptions and drawings of well-known functions and configurations that are determined to unnecessarily obscure the subject matter of the present invention will be omitted.

Regenerative heat storage can be divided into sensible heat storage method and latent heat storage method, and sensible heat storage uses actual temperature rise by heating materials such as water, sand, and gravel, and latent heat storage method uses phase change having a large heat storage density in a specific temperature range. Phase change material (PCM) is a method of heat storage by using the heat of transfer and melting, that is, latent heat.

The heat storage material stores the heat generated by the heat source and emits the stored heat when the heat source is removed or the heat source temperature falls, so that the temperature changes linearly. A material having a large specific heat per unit mass and a high thermal conductivity is used. It is suitable. The most commonly used and used materials for such heat storage materials include water and gravel.

The sound insulation includes sound absorbing material and sound insulating material, and absorbs sound or prevents transmission. It is preferable to select a light and porous material per unit volume, and in general, heat storage material or heat insulating material may be used as sound insulation material.

Therefore, the soundproofing material among heat storage materials can be used as heat storage material and sound insulation material. On the other hand, the room temperature that a person feels comfortable in a residential environment is known to be 18 to 22 degrees Celsius.

The temperature gradient may be a hot portion and a relatively non-hot portion in comparison to other portions when the same plane is heated by one heat source, and thus means a phenomenon in which a temperature difference occurs.

2 is a functional diagram of the warm water ondol panel according to an embodiment of the present invention.

Hereinafter, with reference to the accompanying drawings, the hot water ondol panel 100 is the first guide groove 110, the second guide groove 115, elution portion 120, fixing projections 122, fixing holes ( 150).

The hot water ondol panel 100 is heated by using the heat of hot water supplied through the hot water hose 140. In this case, any one metal selected from various metals is used to uniformly warm the entire bottom surface. Metals have fast thermal conductivity and can support a relatively large external force, and the entire surface of the floor is quickly and evenly heated by high thermal conductivity.

The first guide groove 110 is in surface contact with the hot water hose 140 disposed in a straight line, and the second guide groove 115 is fixed while being in surface contact with the hot water hose 140 arranged in a curve. At this time, the first and second guide grooves 110 and 115 heat the hot water ondol panel 100 quickly and uniformly while receiving the heat of the hot water while fixing the hot water hose 140 in a surface contact state.

Since the first guide groove 110 and the second guide groove 115 have the same function, it will be described below that the second guide groove 115 is included in the first guide groove 110.

In the prior art, since the hot water hose is provided on the upper surface of the hot water ondol panel and at the same time in line contact, the heat transfer amount is small and the heat transfer is late so that heat cannot be efficiently used.

However, in the present invention, since the hot water hose is provided on the bottom surface of the hot water ondol panel and at the same time, the hot water hose has a wide heat transfer area, thus the heat transfer amount is large, heat transfer is faster, heat is used more efficiently, and boiler fuel is reduced.

The eluting part 120 forms a heat storage space part 124 at the lower side and attaches a separate heat insulating material to the lower reference line 102 to seal the air inside. Enclosed air functions as a heat storage medium that stores heat.

The elution unit 120 is a truncated horn shape having any one shape selected from polygons including a circle, and a truncated cone shape is relatively preferable.

3 is a functional diagram of the cut plane A-A in FIG. 2 according to the first embodiment of the present invention.

Hereinafter, with reference to the accompanying drawings, the heat storage function at the same time the heat storage function and the soundproof function at the same time the heat storage function of the upper wall 126 and the side wall 128 of the heat storage space portion 124 formed inside the elution portion 120 Attached to the soundproofing unit 130 and fixed by a protruding fixing protrusion 122.

In the following description, a lower heat insulating material may be attached and fixed to the lower portion of the lower reference line 102 so as not to leak heat.

Here, the heat storage soundproof unit 130 absorbs vibrations and shocks applied to the upper side of the elution unit 120 to reduce the noise between the floors, at the same time, stores heat generated during the heating process, and the heating is terminated or heated to a temperature lower than the stored heat. In this case, the stored heat is dissipated so that a rapid temperature change does not occur and a linear temperature change occurs.

As the material of the heat storage sound insulation unit 130, any one or more selected from far-infrared radiation materials including rock crushed stone, ceramic, mica, jade, germanium stone and tourmaline may have a diameter of 0.05 mm to 5 mm (mm). A first material composed of minerals ground to a size is formed.

Here, the mica stone is preferably one or more selected from biotite, dolomite, biotite, pulverized sieve sieve (sieve) to select the particles having a size within a certain range.

On the other hand, at least one selected from glass fiber, magnesium oxide, calcium oxide and lead oxide is mixed to form a second material.

The first material and the second material are mixed in the same volume ratio and solidified into a selected shape using a building binder. Here, the binder is preferably used to select any one of the general building binder used in construction.

Binders are called adhesives that connect materials to materials, and are classified into organic binders and inorganic binders. There are also hybrid binders in which organic binders and inorganic binders are mixed.

The building binder is included in the inorganic binder, and the inorganic binder has silicon as a main component and has a high bonding strength with the adherend.

The first material emits far-infrared rays of wavelengths beneficial to the human body and has excellent thermal conductivity due to its active molecular activity.

In comparison with the heat storage performance of the heat storage material sample and salt solution heat storage material sample having a different size of mineral particles including the mica by one experiment as shown in Table 1 below.

order Elapsed time Sample-1 (Celsius) Sample-2 (Celsius) Salt solution (Celsius) One  0 min 24.5 degrees 24.6 degrees 24.6 degrees 2  5 minutes 35.0 degrees 29.0 degrees 31.8 degrees 3 13 mins 48.5 degrees 36.2 degrees 41.2 degrees 4 19 mins 50.8 degrees 42.5 degrees 45.3 degrees 5 25 mins 52.6 degrees 46.7 degrees 47.1 degrees 6 32 mins 54.7 degrees 49.5 degrees 50.4 degrees 7 38 minutes 56.4 degrees 51.9 degrees 51.6 degrees 8 42 minutes 57.7 degrees 53.7 degrees 52.2 degrees

Referring to Table 1 in detail, the environment where the experiment was started was 25 degrees Celsius, all the heat storage material samples were limited to the same volume, and heated in the same conditions for a total of 42 minutes using an electric heater.

Here, Sample-1 has a size of mineral particles of 2.0 millimeters, Sample-2 has a size of mineral particles of 0.05 millimeters, and the salt solution is 70% by weight of brine.

Analyzing the results, Sample-1 had an average temperature increase of 7.9 degrees Celsius per unit time of 10 minutes, increasing 33.2 degrees Celsius for a total of 42 minutes of experiment time, and Sample-2 had an average of 6.93 degrees Celsius per unit time of 10 minutes, The temperature rose 29.1 degrees Celsius in total, and the salt solution rose 6.57 degrees Celsius and 27.6 degrees Celsius in average per unit time of 10 minutes.

And it takes about 20 minutes for the sample-1 takes about 20 minutes from the room temperature, and about 40 minutes for the brine, it can be seen that the excellent heat storage performance of the mineral heat storage material according to the present invention.

It can be seen that Sample-2 having a small particle size of mineral particles including mica has a slightly lower heat storage performance than Sample-1, and a larger particle size of the mineral improves the thermal storage performance.

Therefore, the size of the particles is preferably in the range of 0.05 to 5 millimeters in diameter, most preferably 2.0 millimeters in diameter.

In addition, a phase change material (PCM) may be selected and used as a material of the heat storage soundproof unit 130.

A phase change material (PCM) is a substance that stores heat or releases stored heat as its state changes from solid to liquid or from liquid to solid.

4 is a diagram illustrating a temperature conversion state of a phase change material used as a heat storage material in the present invention.

Hereinafter, with reference to the accompanying drawings in detail, the phase conversion material is turned into a solid at a temperature lower than the melting temperature of the melting material, and in the solid state only the temperature up to the melting temperature when heat is applied.

When the temperature is higher than the melting temperature, the liquid is converted into a liquid, and when the heat is applied, only the temperature is maintained while maintaining the liquid state.

As such, the heat required when the temperature rises in the solid or liquid state is called sensible heat. The opposite happens when the temperature is lowered.

On the other hand, at the melting temperature, the solid and the liquid state coexist, and even when heat is applied, only the state change of the object, that is, phase change, is used only for the temperature change does not occur in the object, this heat is called latent heat (latent heat).

Therefore, latent heat is the heat absorbed or released when a substance converts from solid to liquid, liquid to solid, liquid to gas, and gas to liquid.

In general, latent heat is greater than sensible heat, for example water absorbs 80 cal (335 J, Joule) per gram (g) of water when converting from solid ice at 0 degrees Celsius to liquid water. It is equal to the amount of heat it takes to warm water from 0 degrees Celsius to 80 degrees Celsius.

Since the phase transition temperature and the heat storage capacity of the phase change material have different characteristics for each material, it is preferable to select and use an appropriate phase change material according to the purpose of use.

In the present invention, a paraffin-based phase conversion material is used, and phase transformation characteristics of melting temperature, condensation temperature, and heat storage capacity are different according to the type of paraffin, as shown in Table 2 below. It is preferable to select and use a suitable phase change material.

Phase change material Melting temperature Condensation temperature Heat storage capacity Sample 1 -3 degrees Celsius -4 degrees Celsius 165 kJ / kg Sample 2 6 degrees centigrade 2 degrees Celsius 214 kJ / kg Sample 3 7 degrees centigrade 5 degrees Celsius 156 kJ / kg Sample 4 8 degrees centigrade 6 degrees centigrade 174 kJ / kg Sample 5 22 degrees celsius 20 degrees celsius 130 kJ / kg Sample 6 28 degrees celsius 26 degrees celsius 179 kJ / kg Sample 7 31 degrees celsius 31 degrees celsius 169 kJ / kg Sample 8 35 degrees celsius 35 degrees celsius 157 kJ / kg Sample 9 43 degrees celsius 42 degrees celsius 174 kJ / kg Sample 10 52 degrees celsius 52 degrees celsius 167 kJ / kg Sample 11 55 degrees celsius 54 degrees celsius 179 kJ / kg Sample 12 59 degrees celsius 59 degrees celsius 184 kJ / kg Sample 13 64 degrees celsius 63 degrees celsius 173 kJ / kg Sample 14 81 degrees celsius 80 degrees celsius 175 kJ / kg Sample 15 99 degrees celsius 102 degrees celsius 168 kJ / kg

In the present invention, the optimal material is selected from the hot water ondol panel among these phase change materials and impregnated with the nonwoven fabric.

Impregnation is achieved by impregnating (penetrating) 1 to 3 kilograms (Kg) per unit area by a meter by mixing paraffin, the selected phase change material, in a liquid state and mixing with an adhesive aqueous resin.

As described above, the heat storage material made of paraffin is cured by aqueous resin in the state of impregnation with the nonwoven fabric to have a soft solidified shape.

Thus, the heat storage soundproof unit 130 of the present invention made of a mineral material or a phase change material stores heat by linear temperature change characteristics and gradually releases the stored heat to linearly change the temperature of the ondol or phase change ( Due to the latent heat characteristics, which are phase transitions, the temperature change is linearly delayed to provide a comfortable change in the heating temperature in the residential space.

Therefore, the present invention uses any one selected from a heat storage material solidified by impregnating paraffin, which is a phase change material, with a nonwoven fabric, and solidifying by bonding various mineral particles with a building binder.

Soundproof material in the present invention is to include both sound-absorbing material and sound-absorbing material to block the noise.

In addition, since the heat storage material or the heat insulating material generally includes a soundproof function, the heat storage material is also used as the sound insulation material.

Therefore, the heat storage soundproof unit 130 of the present invention selects any one of the non-woven fabric impregnated with the mineral heat storage material and the phase change material described above, and is used for heat storage and sound insulation.

In the following description, the heat storage soundproof unit 130 using minerals as heat storage and soundproofing materials may be configured to be solidified into a shape selected by each embodiment from the beginning or filled in a liquid state to be changed into a solidified state.

The elution unit 120 attached to the heat storage soundproof unit 130 in a fixed state therein functions as a heat storage function and a sound insulation and sound insulation function when vibration or shock is applied.

FIG. 5 is a functional diagram of the cut line B-B in FIG. 2 according to the second embodiment of the present invention.

Hereinafter, with reference to the accompanying drawings, the heat storage sound insulation 130 is formed and fixed to the entire upper wall 126 and the side wall 128 inside the elution portion 120. At this time, the heat storage space portion 124 is formed.

FIG. 6 is a functional diagram of the cut line B-B in FIG. 2 according to the third embodiment of the present invention.

Hereinafter, with reference to the accompanying drawings, the entire inside of the elution unit 120 is filled with the heat storage sound insulation 130, or fixed, or the top wall 126, side walls 128, the center 129 Filled with a portion 130 to fix.

7 is a partial cross-sectional view showing a mortar plastered on a hot water ondol panel according to a first embodiment of the present invention.

Hereinafter, with reference to the accompanying drawings, as the AA cut surface of the hot water ondol panel 100, the heat insulating material 200 is attached to the lower portion of the hot water ondol panel 100, the mortar 300 is fixed height ( Plaster and finish by thickness). Here, there may be a method for not attaching the heat insulator 200.

It has already been described that the hot water hose 140 is provided below the first guide groove 110 and the heat storage soundproof unit 130 is provided below the elution unit 120.

Although the hot water hose 140 is provided at the lower side of the second guide groove 115, which is not shown in the drawings, it will be described as being included in the first guide groove 110.

The heat insulator 200 is to prevent the heat generated by the hot water hose 140 and the hot water ondol panel 100 from leaking downward, and preferably, a high density styrofoam having a thickness of about 50 millimeters (mm) is used.

Mortar (300) is generally a mixture of sand and cement in water in the construction is a material that is overlaid for plastering or finishing. In the present invention, it is preferable to mix ocher, elvan, charcoal powder, jade powder and the like.

At this time, the blending ratio is preferably a mixture of 45% ocher 45% + (sand + ceramics + lamellar + germanium + charcoal powder) + 10% cement in a volume ratio.

Alternatively, it is more preferable to finish the ocher 45% + (sand + ceramics + bar stone + germanium + charcoal powder, etc.) and mix and plaster the glutinous rice paste with diluted paste.

Here, the first guide groove 110 is heated by the hot water hose 140 provided in the lower portion and dissipates heat to the upper side, the elution portion 120 is the hot water ondol panel 100 in surface contact with the hot water hose 140. It is heated by the transferred heat and dissipates heat to the upper side.

When a certain amount of time has elapsed after the heating is started, the temperature of the upper side of the first guide groove 110 plastered with the mortar 300 and the temperature of the upper side of the elution unit 120 are different.

That is, there is a difference between the calorific value Q1 generated in the first guide groove 100 and the calorific value Q2 generated in the elution portion 120, and the surface temperature of the mortar 300 maintaining the gap between l1 and l2, respectively. Is different from t1 and t2.

In general, it is desirable that the heated floor of a residential environment maintain a uniform temperature as a whole so that there is no temperature gradient.

Here, the technique of the present invention is to adjust the height of the mortar (300) to equal the temperature of t1 and t2.

Heat moves from high temperature to low temperature, and there are three kinds of heat transfer: conduction, convection, and radiation.

Convection is a phenomenon in which a liquid or a gas changes in density due to thermal expansion, and each part is warmed by circulating motion. Radiation is a phenomenon in which heat moves directly without intervening with other materials. The phenomenon is as if heat is transferred directly from the stove to feel warm.

Conduction is a phenomenon in which heat moves into a fixed object, and according to the Fourier law as follows, the heat can be calculated by the following equation.

[Equation]

Q = (kS (T2-T1) t) / (ℓ * ℓ)

k: constant

Q: Calories

S: cross section

(T2-T1): temperature difference between the heat source surface and the heat generating surface

ℓ: distance between heat source side and heat generating side

t: time

Here, the heat quantity Q is proportional to the cross-sectional area S, and the temperature difference T2-T1 between the two surfaces by the heat source surface and the heat generating surface is proportional to the time t, and inversely proportional to the square of the distance ℓ between the two surfaces. .

The thermal conductivity of materials used in construction is shown in Table 3 below.

Material name Thermal Conductivity (kcal / mh ℃) plate copper 333 aluminum 204 Iron (mild steel) 41 nonmetal soil 0.53 Sand (dry) 0.42 water 0.52 concrete Plain concrete 1.41 Plastering Materials mortar 0.93 wood Pine tree 0.15 Plywood 0.11 Ceramic products tile 1.10 Ordinary brick 0.53 Glass 0.67

The hot water ondol panel 100 according to the present invention has a thermal conductivity of 41 (kcal / mh ° C.) when iron (mild steel) is used, and 333 (kcal / mh ° C.) when copper (Cu) is used.

Soil thermal conductivity is 0.53 (kcal / mh ℃) and mortar is 0.93 (kcal / mh ℃).

Therefore, in thermal conductivity, the thermal conductivity of the hot water ondol panel 100 made of a metal plate is higher than that of soil or mortar used as a plastering material, and thus heat is rapidly transferred.

That is, since the hot water hose is provided at the lower side of the metal plate and at the same time, the hot water ondol panel 100 is heated quickly and uniformly.

Therefore, the amount of heat Q1 generated on the upper surface of the upper portion of the first guide groove 110 and the amount of heat Q2 generated on the upper surface of the elution portion 120 may be assumed to be the same after a predetermined time elapses. .

FIG. 8 is a plan view of a part of a state without mortar on the hot water ondol panel according to FIG. 7; FIG.

Hereinafter, with reference to the accompanying drawings, the elution portion 120 has a diameter of R, the first guide groove 110 has a width of D.

In an embodiment, the diameter R of the elution unit 120 is 9.4 centimeters (cm), and the width D of the first guide groove 110 closely contacting the hot water hose 140 in surface contact is 2 centimeters. It is assumed that the length is 9.4 centimeters equal to the diameter of the elution unit 120. Here, each of the eluting parts 120 maintains the same distance in the vertical, vertical, left, and right directions so that the first guide groove 110 is longer as D in the longitudinal direction.

At this time, the area ratio of the area of the first guide groove 110 and the elution portion 120 is about 1: 3.

Substituting these results into the equation, the calories for Q1 and Q2 in FIG. 7 corresponding to S1 and S2 in FIG. 8 are calculated, respectively, and Q1 = (kS (T2-T1) t) / (ℓ1 * ℓ1 ) = (1 (T2-T1) t) / (ℓ1 * ℓ1) 'and' Q2 = (kS (T2-T1) t) / (ℓ2 * ℓ2) = (3 (T2-T1) t) / (ℓ2 * l2) '.

In this case, since the values of each (T2-T1) and t can be assumed to be the same, the values of 1 are substituted.

In this case, 'Q1 = 1 / (ℓ1 * ℓ1)' and 'Q2 = 3 / (ℓ2 * ℓ2)', and '(ℓ1 * ℓ1) * Q1 = (ℓ1 * ℓ1)' and '(ℓ2), respectively. * l2) * Q2 = 3 (l2 * l2) '.

And since the calories of Q1 and Q2 are required to be the same, and (ℓ1 * ℓ1) and (ℓ2 * ℓ2) can be assumed to be the same value, it becomes '(ℓ1 * ℓ1) = 3 (ℓ2 * ℓ2)'.

Since the calorie value is inversely proportional to the square of the distance l, the length of l1 becomes about 1.7 times the length of l2, so that the temperature t1 by the calorie of Q1 and the temperature t2 by the calorie of Q2 are equal.

Here, the value of the constant k is not reflected, and since the constant value is a decimal point value of 1 or less, the length of L1 becomes 1.7 times or less of the length of L2.

Therefore, the hot water ondol panel 100 according to the present invention is about 1.7 cm in the first guide groove 110 when the mortar 300 is plastered at a height of about 1 centimeter in the first guide groove 110 and the elution portion 120. Plaster mortar at a height no greater than centimeters.

That is, in order to make the temperature of the upper layer of the first guide groove 110 and the eluting portion 120 the same, the height of the guide groove 110 is lower than the eluting portion 120 to 0.3 to 0.7 centimeters or less, and 0.5 centimeters. It is more preferable to set it as low.

And it is preferable to finish the mortar 300 by plastering to a height of 0.8 to 1.2 centimeters (thickness) and to a thickness of 1 centimeter.

9 is a partial cross-sectional view showing a mortar plastered on a hot water ondol panel according to a second embodiment of the present invention.

Hereinafter, with reference to the accompanying drawings, the arc of the first guide groove 110 is in a downward state, the hot water hose 140 is seated in a surface contact state with the upper surface of the first guide groove 110. .

The heat storage soundproof unit 130 is fixed to the upper surface inside the eluting unit 120 by the fixing protrusion 122.

Here, the elution unit 120 preferably has a rectangular horn shape rather than a cone shape, and the hot water ondol panel 100 provided with the elution unit 120 and the first guide groove 110, etc., is roll-formed. It is preferable to form in a manner.

The mortar 300 is filled up to the height of the elution unit 120 on the hot water hose 140 seated in the first guide groove 110.

In this case, since the hot water hose 140 is in direct contact with the mortar 300 having low thermal conductivity and the elution part 120 is in surface contact with the hot water hose 140 through metals having high thermal conductivity, the temperature at the surface of the mortar 300 ( t1) and the heat quantity Q1 and the temperature t2 and the heat quantity Q2 on the upper surface of the elution part 120 are kept the same.

The present invention of the configuration described in the elution portion 120 of the hot water ondol panel 100 simply formed of a sheet of metal, the heat storage soundproofing unit 130 having a heat storage and soundproof function in a space formed inside the various shapes It is composed of any shape selected from among the mass production at a lower cost than the prior art, and simply installed to eliminate the noise between floors and at the same time accumulate more calories than the prior art, saving heating fuel without sudden temperature change of heating. You can do that.

In addition, the hot water ondol panel 100 is configured so that the hot water hose is disposed at the lower side of the guide groove so that the hot water is efficiently used, and in particular, the height of the guide groove is lower than the height of the eluent so that the temperature difference in the mortar plastering is completed. There is an advantage that does not occur.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
