Description

Indoor heating method using high-purity carbon tile flooring {HEATING METHOD FOR ROOM WITH HIGH PURITY CARBON TILED FLOOR}

The present invention relates to an indoor heating method of heating a room by supplying hot water to an indoor floor made of a carbon tile (Carbon Tile), and more particularly, an appropriate temperature on the floor of a room where a carbon tile is installed as a flooring material. The present invention relates to an indoor heating method using a carbon tile flooring material which can maintain an optimal state of a room by supplying an appropriate amount of hot water and can rationalize energy use.

In winter, hot water is generally used to heat an interior of an apartment or detached house. The hot water is supplied from a district heating system or a boiler (individual heating) installed in each home.

When using a boiler installed in each home as a hot water supply source, the rationalization of energy use is achieved because the flow rate of hot water is controlled to reach the set room temperature according to the room temperature set by the user regardless of the outside temperature. it's difficult.

When the hot water is supplied from the district heating system, the hot water is supplied at the proper temperature in consideration of the outside temperature. Therefore, it is possible to rationalize the use of energy compared to the individual heating. In case of supply and low outside temperature, since it relies on the so-called proportional control to supply high temperature hot water, there is still room for improvement because no precise control is made.

On the other hand, when heating the room using hot water, the amount of heat to be supplied differs according to the indoor conditions, and even if the appropriate amount of heat is supplied, the building object to be heated consists of a structure such as concrete, so the room temperature is actually increased by the supplied heat. Because it takes a long time to achieve a pleasant indoor condition until the indoor temperature is a proper temperature, therefore, a comfortable and economical heating can be achieved only by supplying heat energy at an appropriate time according to various indoor conditions.

Recently, in order to solve the above problems, attempts have been made to achieve comfortable indoor heating by controlling the temperature of hot water and supplying it at an appropriate time by using the temperature of the next day predicted by the Korea Meteorological Administration. It is a method of predicting the outside air temperature during the day by inputting the highest temperature and the lowest temperature and time in the following Equations 1 to 3 of the DOE-2 program of the Department of Energy.

However, in the above method, the heating load of the target building is calculated based only on the daily maximum and minimum temperatures provided by the Korea Meteorological Administration without any consideration of the building's orientation and the presence of obstacles blocking the sun's heat. There may be a difference from the heating load actually required, in this case not only can not be comfortable heating, but also can not rationalize the use of thermal energy.

On the other hand, carbon tiles made of carbon materials are used because of their excellent ability to emit far infrared rays and air purification as ondol beds. In the case of using such carbon tiles as indoor flooring materials, the thermal conductivity is high and the heating conditions are different from the existing indoors using concrete or cement mortar as flooring materials. This must also be taken into account for the heating to take place.

The present invention has been devised in response to the above requirements, the present invention is to maintain the interior in an optimal state by supplying hot water at an appropriate temperature calculated by reflecting the actual outside temperature to the indoor floor installed with carbon tiles as a flooring material In addition, the object of the present invention is to provide an indoor heating method using a carbon tile flooring material that can promote the rational use of energy.

An object of the present invention as described above, the indoor heating method using a carbon tile flooring, the outside air temperature prediction step of the outside air temperature change during the day based on the weather data of the next day provided by the Meteorological Administration; A predicted supply calorific value calculating step of calculating a predicted supply calories to be supplied to the room in advance in order to heat the room to be heated to an appropriate state on the basis of the outside temperature prediction curve for the day determined by the outside temperature predicting step; Calculating an average temperature difference calculating an average of the temperature difference between the predicted outside temperature and the actually measured outside temperature; The temperature of the hot water is determined from the estimated supply calories to be supplied to the room by the predicted supply calorific value calculating step, and the set temperature of the TCV is adjusted by adding or subtracting the average temperature difference calculated by the average temperature difference calculating step from the determined hot water temperature. Adjusting the temperature control valve; It is achieved by configuring.

The present invention uses a carbon tile having a much better heat transfer performance than a general flooring material as a flooring material, thereby improving heat response compared to the prior art, thereby shortening the adjustment period of the temperature control valve, and thus, compared with the conventional method. The room temperature can be controlled to be much closer to real time.

In addition, the present invention can adjust the temperature of the hot water supplied to the room by reflecting the actual outside temperature to maintain the room in an optimal state and at the same time to rationalize the use of energy.

In addition, the present invention provides finer and more accurate indoor temperature control by finely adjusting the corrected hot water temperature of TCV according to the change of the actual indoor temperature, thereby achieving comfortable indoor heating.

In particular, since the present invention uses carbon tiles as flooring materials, the carbon tile has a unique effect, that is, a large amount of far-infrared radiation effect when heated above a certain temperature, and also can be expected to effect such as air cleaning, humidity control, antibacterial.

On the other hand, the outside temperature prediction curves obtained by Equations 1 to 3 above do not reflect the orientation of the building to be heated and the presence or absence of obstacles to block solar heat. It may be different from the outside temperature, and accordingly the estimated supply calories calculated by the predicted supply calories calculation step (S200) (

Hot water at a temperature calculated by Equation 6 based on

) In the room can be supplied to the room more than the energy required or less than the actual amount of heat energy can be supplied to the room, in this case, you can not expect comfortable heating.

That is, assuming that the predicted outdoor temperature is 5 ° C and the actual outside temperature is 6 ° C, when the hot water at the temperature determined by Equation 6 is supplied to the room, more heat energy is supplied to the room than is actually required. If the continuous supply of thermal energy to the room according to the predicted room temperature generated by Equations 1 to 3 as described above, over- or under-supplied heat energy may accumulate in the room, and in this case, control of an appropriate room temperature This can be difficult.

As described above, the supply temperature of the hot water supplied to the room (

) Is controlled by the set temperature of the TCV.

) Is determined by Equation 6, and the supply temperature (

When the hot water is supplied according to the present invention, the supply temperature of the corrected hot water supplied by the TCV is provided in the present invention because excess or excessive heat energy is supplied to the room.

Is the hot water supply temperature calculated by Equation 6, as shown in Equation 9 below.

), The average temperature difference calculated by Equation (8)

The temperature is set to the temperature at which the temperature is subtracted from), whereby the rise or fall of the room temperature due to the excessive or undersupply of thermal energy is suppressed, thereby making the room heating comfortable.

In the present invention, since the carbon tile having a thermal conductivity of 136.33 W / mK at room temperature (about 26 ° C.) is used as the flooring material, the heat transfer performance is superior to that of the general flooring material, and thus the thermal response is much improved compared with the conventional flooring material. The adjustment interval of the control valve can be shortened, and thus the room temperature can be controlled to be much closer to real time than the conventional method.

In the present invention, the carbon tile used as the flooring material is, for example, carbonaceous material having a surface area of 660 to 1,320 m 2 per 1 g, carbonized at 2,000 to 2,500 ° C. at a high temperature of 99% high purity carbon material in which impurities are completely removed. It is composed of components, thereby excellent oxidation (Oxidation) and reduction (Deoxidize) function, anti-corruption and deodorizing function can be expected.

(5) Net temperature correction step (S500)

In this step, the adjusted hot water temperature of the TCV is finely adjusted according to the actual room temperature change.

When the interior of the room is heated by the above-described steps, a precise control of the hot water supplied to the room is performed according to the set temperature set by the user, thereby achieving comfortable heating.

However, the heating load may be reduced when the indoor resident uses a computer or a kitchen appliance. Although the present invention controls the real time by using carbon tile as a flooring material, the hot water supplied to the room is basically predicted by the outside air temperature. Because of controlling the temperature of the temperature may be different between the actual room temperature and the user-set room temperature.

Accordingly, the present invention optionally provides a net temperature correction step (S500) to further eliminate the difference in the room temperature, this step and the actual room temperature for a certain period periodically as shown in Equation 10 below After calculating the difference between the room temperature set by the user, as shown in Equation 11 below, the step of adding or subtracting this temperature difference from the set temperature of the TCV obtained by Equation 9, thereby controlling more precise and accurate room temperature Pleasant room heating can be achieved.
