Description

TECHNICAL FIELD [0001] The present invention relates to a hybrid heating apparatus using a latent heat structure, and a heating method using the latent heat structure.

The present invention relates to a heating apparatus and method using a latent heat structure. More particularly, the present invention relates to a heating apparatus and method using a latent heat material that is liquefied by absorbing heat from a heating pipe and an electric hot line during heating, The present invention relates to a hybrid heating apparatus using a latent heat structure capable of achieving a greater oil energy saving effect by performing heating using a modular latent heat structure filled with a heat source, and a heating method using the latent heat structure.

Generally, wet heating construction method and dry heating construction method are applied as a heating piping construction method for an apartment, a townhouse, or a house such as a single house.

BACKGROUND ART Conventionally, in a widely-used wet heating method, a heat insulating plate for heat insulation and sound insulation is laid on a concrete slab, a lightweight foamed concrete is laid thereon and cured, a heating pipe is installed thereon with a fixture, And after curing, a finish material such as a floorboard or a floor panel is typically installed.

Meanwhile, in the above-mentioned wet heating method, there is a problem that curing of lightweight foamed concrete and mortar is time-consuming and leveling is required, which is troublesome. Therefore, the application of dry heating method is gradually increasing have. In the dry heating method, a heat insulating plate such as a silver foil film or a polyethylene film with a copper foil film is laid on a concrete slab, and a heating pipe support plate made of PVC compression insulation is laminated, A soundproof and cushion layer is laminated thereon, and then a covering material is laminated thereon.

However, since the conventional wet heating or dry heating as described above is based solely on a method of circulating hot water by circulating hot water through a heating pipe, the specific heat of water is only 1 cal / g when the heating is released, Thereby causing the room temperature to drop at a relatively high speed.

Therefore, it requires a relatively long cycle of heating for a long period of time in order to achieve sufficient heating in the winter season, which is a problem in that the heating cost is large and thus burdens the household economy.

As a conventional method for solving the above-mentioned conventional problems, there has been used a method of installing a ceramic layer such as sand and gravel or crushed stone in a heating or dry heating installation on a heating pipe portion or an upper layer thereof as a heat storage layer, It is useful to extend the holding time of the residual heat by installing a solid ceramic layer such as a bar, but the heating effect is delayed at the time of initial heating.

As a typical example of installing such a heat storage layer, Patent No. 0635374 (Registered on Oct. 11, 2006), a waterproof sheet and a heat insulating material are uniformly laid on the upper surface of a concrete slab, and then an emboss board made of a plated steel plate, a galvanized plate, And a method of applying floor heating structure using embossed plate and mortar mortar in which a heat accumulating cell is formed, applying a method of laying and piping and laying a meshed layer with yellow mortar.

However, the above-mentioned conventional technology has a problem that the heat storage cell is formed of a large number of circular protrusions made of a metal plate having good thermal conductivity and corrosion resistance, so that the room temperature is drastically lowered due to rapid heat dissipation when the heating is interrupted.

On the other hand, latent heat is heat that is absorbed or released during phase transition such as melting or evaporation. Unlike the sensible heat that increases the temperature of the system when heat is applied to the material, the latent heat is the temperature of the system Is used for phase transformation, not rise, and the latent heat is usually considerably larger than the sensible heat.

Generally, the latent heat material refers to various phase change materials such as a heat storage material, a cold storage material, a heat control material, and the like, and classified into a high temperature latent heat material, a latent heat latent heat material and a low temperature latent heat material do.

The latent heat material described above is utilized in various fields, and the latent heat material is also applied to the heating of buildings. Currently, latent heat is used in the heating of buildings. It is mainly used for solar heating, but it is applied to other regenerative boilers. However, there are few examples applied to Ondol heating system using hot water piping.

In the solar heating system or the regenerative boiler, the hot water is passed through the hot water pipe into the external heat exchanger accommodated in the latent heat material, and the hot water heated by the heat exchange is circulated through the heating pipe.

Therefore, a structure and a construction method capable of dramatically increasing the heating efficiency while maintaining the conventional wet or dry heating construction structure have been demanded in the art for a long time.

The applicant of the present invention has found that the latent heat structure having the latent heat material embedded therein is installed on a concrete slab in a room requiring heating and the heating pipe is allowed to pass through a groove formed in the latent heat structural body in the registered patent No. 10-1385538 A heating method using a latent heat structure for heating which can obtain a long heating effect by latent heat of a latent heat structure has been developed.

However, the heating apparatuses using the conventional latent heat structures as described above have a limitation in reducing the energy of oil for heating because the heat is accumulated in the latent heat structure using only the heat of the heating pipes.

Generally speaking, a relatively low temperature region The latent heat material and the intermediate latent latent heat material which cause a phase change are preferable. Since the latent heat latent heat material is mainly used as a refrigerant, such a latent heat material can be variously manufactured by varying the composition ratio thereof by using various kinds of compounds. , Which are well known in the art.

When the above intermediate or intermediate latent heat latent heat medium is additionally used, it is preferable to use a paraffinic system such as hexadecane, heptadecane and octadecane, a mixed molten salt of NaAlCl4 molten salt system, sodium chloride, sodium hydroxide and sodium acetate as disclosed in GB2,046,506 Swellable polymer as a nucleating agent, a water swelling polymer as a coagulating agent and a thickener as a main component, or thermopia-32 as a main component, calcium thiosulfate as a nucleating agent and carboxymethyl cellulose as a thickening agent and a thermosetting agent as a thickener, A latent heat material having a latent heat capacity of about 187 to 215 jul / g, which is contained in the trade name G-Pack of FMS Korea, can be used.

However, as shown in FIG. 4, The heating pipe 20 and the electric heating wire 30 may be U-shaped to accommodate the heating pipe 20 and the electric heating wire 30 when the heating pipe 20 and the electric heating wire 30 are to be bent in a U shape.

Or the case 11 of the latent heat constructing body 10 is bent into an L shape as shown in FIG. 5, so that the U-shaped heating pipe (not shown) is heated on at least a part of the vertical side wall So that the heating effect can be given to the vertical wall.

Meanwhile, the heating pipe 20 is inserted into the pipe receiving groove 12 of the latent heat generating structure 10 and is placed thereon to transfer heat to the latent heat generating structure 10. The heating pipe 20 is connected to a boiler (not shown) to form a hot water flow path heated by the boiler.

The electric heating wire 30 is inserted into the heat sink groove 13 of the latent heat structural body 10 and is received by the power supply unit to transmit heat to the latent heatable structure 10.

The electric heating line 30 can receive electric energy from various known power supply means, preferably electricity generated by night-time electricity, solar light, or solar heat. For example, the power supply unit may include a power generation unit for generating electric energy from sunlight or solar heat, a rechargeable battery for accumulating electric energy produced in the power generation unit, a controller for applying electric energy of the rechargeable battery to the electric heating line, . ≪ / RTI > The power generating unit may be a solar cell or an electric heat collecting plate, and the controller may use a controller for controlling the operation of the boiler.

On the other hand, the heating apparatus of the present invention using the latent heat structure 10, the heating pipe 20, and the electric hot wire 30 can be constructed as follows.

First, as a wet heating construction method, a heat insulating plate 2 for insulation and sound insulation is provided on a concrete slab 1, and lightweight foamed concrete 3 is placed thereon for curing. A plurality of the latent heat structures (10) are arranged on the lightweight foamed concrete (3). At this time, it is preferable to dispose the latent heat structure 10 as shown in Fig. 4 or Fig. 5 at a portion where the bottom and the wall meet.

The heating pipe 20 is installed so as to receive the heating pipe 20 inside the pipe receiving groove 12 of the latent heat structure 10 so that the electric heating wire 30 is accommodated inside the heating groove 13 The electric hot wire 30 is installed.

Next, a cement mortar is placed and cured to cover the latent heat structure 10, the heating pipe 20 and the electric hot wire 30 to form a bottom layer 4, and a finish material 5 ).

In this case, the heating device of the present invention can be applied by applying the wet heating method. However, the present invention can be applied to the dry heating method as well as the sound heating cushioning material Not shown) may be intervened.

Next, a heating method using the heating apparatus according to the present invention will be described.

As described above, the heating apparatus of the present invention has a structure in which the heat pipe 20 and the electric hot wire 30 are combined with the latent heat structure 10. Therefore, the heating pipe 20 and the electric heating line 30 can be selectively used to perform heating.

For example, when electric power is applied to the electric heating wire 30 to generate electric heat, the heat of the electric heating wire 30 heats the floor to perform the primary heating and at the same time heating the latent heat storage structure 10 . At this time, the latent heat material inside the latent heat structural body 10 is liquefied while absorbing heat.

Then, when the set time has elapsed or the room temperature reaches the set temperature, the electric power supplied to the electric heating wire 30 is cut off and the heating of the electric heating wire 30 is stopped. In this case, the supply of heat to the latent heat constructing body 10 is interrupted, and the latent heat of the latent heat generating structure 10 is gradually solidified and the heat is released. As a result, the latent heat can be maintained by the latent heat.

Then, when the set time has passed or the room temperature has dropped to the set temperature, the boiler is operated to flow the hot water through the heating pipe 20 to perform the secondary heating. At this time, the latent heat material of the latent heat structural body 10 is again absorbed heat by the hot water flowing along the heating piping 20 to be liquefied.

When the set time has elapsed or the room temperature rises to the set temperature, the operation of the boiler is stopped, the flow of the hot water through the heating pipe 20 is stopped, and the latent heat of the latent heat structure 10 is heated.

When the primary heating is performed through the electric heating line 30 and the secondary heating is performed through the heating piping 20, the heating time through the heating piping 20 can be reduced, It is possible to save a great deal.

The hot water flow of the heating pipe 20 by the heating operation of the electric heating wire 30 and the operation of the boiler is performed by the controller of the boiler described above.

The embodiment of the heating method described above exemplifies a method of performing heating by sequentially using the electric heating line 30 and the heating piping 20. [ However, if the high-speed heating is to be performed differently, the electric heating line 30 and the heating piping 20 may be simultaneously used to perform heating.

That is, electric power is applied to the electric heating wire 30 to heat the electric heating wire 30, and hot water is flowed through the heating pipe 20 to heat the latent heat generating structure 10, It is possible to shut off the power applied to the heat pump 30 and stop the flow of the hot water through the heating pipe 20 to perform the heating by the latent heat of the latent heat structure 10. [

As described above, according to the present invention, since the latent heat structure 10 selectively absorbs heat from the electric heating line 30 and the heating piping 20 to maintain the latent heat, it is possible to maximize the heating effect while minimizing the use of the petroleum energy. There is an advantage to be able to.
