The barn heating system 100 according to the first embodiment of the present invention, as shown in Fig. 1, the floor 20 as viewed from above to evenly heat the interior space 50 of the barn 10 The carbon heating members 110 are disposed at predetermined intervals so as to be spaced apart from the floor 20 by dividing into several equal parts. The livestock house heating system 100 further includes a controller 160 that can control the temperature of the internal space 50.

As shown in FIG. 1, the barn 10 is connected to the wall 30 formed on the bottom of the bottom 20, the wall 30 formed on the side surface of the floor 20, and the wall 30, and an upper portion of the wall 30. It has an internal space 50 consisting of a roof 40 to form a. Accordingly, the carbon heating member 110 may evenly heat the internal space 50 of the livestock house 10. For convenience of explanation, the vertical direction of the width direction of the barn 10 in the “X” direction, the length direction of the barn 10 in the “Y” direction, and the bottom 20 of the barn 10 toward the roof 40. Set the direction in the “Z” direction respectively.

As illustrated in FIG. 2, the carbon heating member 110 may include a carbon heating yarn 123 coated with a carbon compound to generate heat by a power supplied from the outside, and a current supplied from the outside to the carbon heating yarn 123. A lifting unit 233 including a conductive member 127 electrically connected to both ends of the carbon heating yarn 123 is provided. The carbon heating member 110 includes an insulating thread 125 that is coupled with the carbon heating yarn 123 and / or the conductive member 127 to improve the strength while forming an overall shape such as a conventional cloth. The carbon heating member 110 has a coating layer 130 coated on both sides of the heating element 120 and the insulating yarn 125. The carbon heating member 110 has a rectangular mat-like shape made of a thin thickness as a whole. The carbon heating member 110 may have various shapes such as an ellipse shape, a rhombus shape, and the like as needed.

Carbon exothermic yarn 123 is prepared by coating a compound containing carbon or / and carbon in the yarn. The carbon heating yarn 123 may have various sizes according to the required heat generation amount, and may be manufactured and bent in a shape such as cloth to have a size such that breakage does not occur in the carbon heating yarn 123. In addition, the amount of heat generated may be adjusted by adjusting the interval (pitch) at which the carbon heating yarn 123 is disposed.

The carbon heating yarn 123 may be woven with the insulated yarn 125 by variously changing according to the required amount of heat generated by the spaced apart vertically or horizontally. That is, the carbon heating yarn 123 is part of the weft yarn and the rest of the weft yarn may be made of the insulated yarn 125, and the inclination may be made of the insulated yarn 125. Of course, the carbon heating yarn 123 may be woven in an inclined manner.

Accordingly, in the carbon exothermic yarn 123, resistance is generated while current flows through the carbon compound by the supplied power, thereby generating heat. At this time, far infrared rays are also emitted from the carbon compound and have intrinsic properties.

Infrared radiation is a kind of electromagnetic waves with a greater thermal effect than the red region of visible light. The wavelength is 25 µm or more, and the wavelength is longer than visible light, so the thermal effect is large and the penetration is strong. In addition, resonance and resonance effects on organic compound molecules are strong. The longest wavelength in infrared is called far infrared. Shorter wavelengths are called near infrared. It is invisible, absorbs well into the material, and has strong resonance and resonance effects on organic compound molecules.

In general, light has a short wavelength and reflects well, and a long wavelength has a property of being absorbed well when it reaches an object. For example, in the water of 30 ℃ hardly feel the warm energy, but sitting in the sun at the same temperature can feel warm because the infrared rays contained in the sun penetrates deep into the skin to create heat. This heat action helps to eliminate the bacteria that cause various diseases, and helps to expand the capillaries and blood circulation and tissue formation. In addition, by touching the water and protein molecules that make up the cells, the cells are shaken finely 2,000 times per minute to activate cell tissue, which is effective in preventing various adult diseases such as aging, promoting metabolism, and chronic fatigue.

In addition, it promotes sweating, pain relief, heavy metal removal, sleep, deodorization, antibacterial, mold propagation prevention, dehumidification, and air purification.It is effective in housing and building materials, kitchen utensils, textiles, clothing, bedding, medical equipment, jjimjilbang. Far-infrared rays are used in many fields such as.

As shown in FIG. 5, the far infrared rays are emitted from the carbon heating member 110 in various directions to be absorbed into the skin of a breeding animal such as a chick. In addition, for the breeding of chicks, breeding of bacteria, various molds, etc., which are likely to be generated inside the mixture of chaff and excreta due to the penetration of far-infrared rays such as chaff and sawdust spread on the bottom 20 of the barn 10. Can be prevented. On the other hand, the far-infrared rays which are not absorbed may be partially reflected to heat the surrounding atmosphere.

As illustrated in FIG. 2, the conductive member 127 is electrically connected to the carbon heating yarn 123 to supply a current, and examples thereof include a metal wire such as copper.

The coating layer 130 includes dust-proof, moisture-proof and / or water-resistant treatments that can be resistant to dust, humidity, and water, as well as an insulable treatment to prevent current from flowing outward. For this purpose, the coating layer 130 may be made of several layers as necessary. As a result, it can be used for a long time even in a harsh environment with a lot of dust and / or water cleaning, thereby improving the durability and reliability of the product.

The carbon heating member 110 includes a power supply member 133 such as an outlet that is coupled to the outside to supply a current to the carbon heating yarn 123.

The carbon heating member 110 is provided with a temperature rising prevention member 140 inside the coating layer 130 that cuts off the power when the temperature rises above the set temperature. Here, as shown in FIG. 4, the temperature increase preventing member 140 may be a bimetal provided at a front side to which power is supplied to the conductive member 127. That is, when provided to the carbon heating yarn 123 to rise to a higher temperature than necessary, the temperature rise preventing member 140 may operate to block the supplied current. Therefore, it is possible to prevent the rise to a high temperature can prevent the fire and the like.

The edge of the carbon heating member 110 surrounds the coating layer 130 with an insulating cover 135 that insulates the electrical heating layer from being electrically in contact with the carbon heating yarn 123. In addition, the carbon heating member 110 may include an accommodating groove 137 into which a rod such as a pipe may be inserted as necessary. The carbon heating member 110 may be provided with a hole (not shown) to which a ring or the like is coupled, and may be connected to the structure of the barn 10, the feed to the water supply pipe, and the like to be hung in the air.

The temperature sensor 150 detects a temperature of the internal space 50 and transmits the temperature to the controller 160. The temperature sensor 150 may also detect and provide a temperature to corners such as corners of the inner space 50 far from the carbon heating member 110 to maintain the temperature deviation of the inner space 50 to the controller 160. Can be. Thus, condensation and the like can be prevented from the corner of the internal space 50.

As illustrated in FIG. 4, the controller 160 controls the temperature of the internal space 50. The controller 160 is based on a sensing result of the temperature sensor 150 sensing the temperature of the internal space 50, a sensing result of an external temperature sensor (not shown) sensing the external temperature, information input from the input unit 165, and the like. By cutting off the power supplied to the carbon heating member 110 or supplying or controlling the amount of power supplied to the current, it is possible to control whether the carbon heating member 110 is rotated or the rotational speed.

The controller 160 utilizes a predetermined map or the like input to the input unit 165 in consideration of the temperature of the area where the livestock such as chicks and the like is active, as well as an area far from the carbon heating member 110. The temperature of the internal space 50 of 10 may be controlled.

As illustrated in FIG. 4, the branch heat generating unit 129 divides the heat generating portion of the carbon heating member 110 into several regions. Although divided into several as necessary, in the present embodiment will be described that divided into three layers in the horizontal direction ("Z" axis direction).

The branch heat generating unit 129 is divided to form a layer in the horizontal direction of the carbon heating member 110 in the embodiment, but may be divided in the longitudinal direction of the carbon heating member 110, or intermittently divided in the horizontal direction to the vertical direction. Can be. Here, the branch heat generating unit 129 is preferably evenly distributed over the internal space 50. Thus, the temperature of the internal space 50 can be maintained more efficiently.

Looking at the method of arranging the carbon heating member 110 in the internal space 50 as follows. As shown in FIG. 1, the carbon heating members 110 are equally disposed in the internal space 50 such that the longitudinal direction of the carbon heat generating member 110 is in the “X” axis direction. However, the carbon heating member 110 may be evenly disposed in the internal space 50 such that the longitudinal direction of the carbon heat generating member 110 is in the “Z” axis direction. When arranging the carbon heating member 110 in the inner space 50, the distance between the wall 30 and the carbon heating member 110 is arranged closer than the distance of other parts in consideration of heat loss of the wall 30, and the like. It is desirable to. For example, in the case where the barn 10 is divided into four parts of the barn 10 by the “X” axis, the carbon heating member (which is slightly closer to the left wall 30 in the area where the first and second equal parts are divided from the left side) It is preferable to arrange the heat generating member 110 and to arrange the carbon heating member 110 toward the right wall 30 in a region where the third and fourth equal parts are divided from the left side. Thus, the temperature inside the livestock house 10 can be maintained more efficiently and evenly within a predetermined range. The carbon heating member 110 may be installed on the wall 30 as necessary. In this case, the coating layer 130 facing the wall 30 in the carbon heating member 110 may be replaced with a heat insulating layer so that heat is only emitted to the area facing the inner space 50 and far infrared rays may be emitted.

In addition, the carbon heating member 110 is spaced apart from the bottom 20 so that animals such as chicks, chickens, etc., which are reared inside the barn 10, do not damage the carbon heating member 110 or clean the bottom 20. Can be prevented from contamination.

In addition, as shown in FIGS. 3A and 3B, the carbon heating member 110 may be rotated so that the air around the carbon heating member 110 may flow while changing the direction of heat generated. do. That is, as illustrated in FIG. 3A, the carbon heating member 110 may rotate within a predetermined range (see “+ α” and “−α” in FIG. 3A), or the carbon heating member 110 may be axial. It can be rotated 360 degrees around “R1” and “R2”. Thus, air flows around the carbon heat generating member 110 to maintain the temperature of the internal space 50 evenly. In addition, the heat generated from the carbon heating yarn 123 by rotating the carbon heating member 110 may be directed in various directions, so that the temperature of the internal space 50 may also be maintained uniformly and evenly.

Referring to Figure 4 describes the operation or control process of the livestock heating system 100 according to the present invention.

First, when power is supplied from the power supply unit 163, current is transmitted to the carbon heating member 110 through the control unit 160. Herein, the controller 160 considers the temperature difference between the external temperature and the internal space 50 and selectively selects which branch heat generating units 129a to 129c to supply power based on information input from the input unit 165. Can be controlled. For example, assuming that the target temperature of the internal space 50 is 34 ° C., and the current external temperature is 28 ° C., in consideration of the current temperature of the internal space 50, the control unit 160 is shown in FIG. 4. As described above, only one of the power supply members 133a is controlled to be turned on so that power is supplied only from one of the branch heat generators 129a to 129c. On the other hand, if the external temperature is 12 ° C. under the same conditions, the controller 160 controls the power supply member to supply power to all three branch heat generating units 129a to 129c among the branch heat generating units 129a to 129c. All of 133a to 133c may be controlled to be on. Thus, the temperature of the internal space 50 of the livestock house 10 can be evenly and uniformly controlled to suit the environment such as the external temperature more efficiently.

In addition, the controller 160 may control the degree of rotation and / or the rotational speed of the carbon heating member 110 in consideration of the temperature distribution of the internal space 50.

As an embodiment applied to the livestock house heating system 100 according to the present invention, the case of raising a newborn chick in the internal space 50 of the livestock house 10, for example, the effect thereof with reference to Figures 6a and 6b. The following description is made.

In general, newborn chicks in eggs are sensitive to temperature and humidity, and the temperature difference is small, the condition of the chicks is good. In other words, always keep about 34 degrees Celsius, and while the chicks are growing, the temperature should be lowered little by little. The smaller the temperature deviation, the better the growth of the chicks.

First, it is assumed that the internal space 50 of the barn 10 is maintained at 20 degrees Celsius.

First, Figure 6a shows the temperature change according to the time of the interior space 50 when using a conventional hot air dryer, Figure 6b shows the time of the interior space 50 when using the livestock heating system 100 according to the present invention It is a graph showing the temperature change according to.

That is, as shown in FIG. 6A, the temperature change period (see “t1”) is six times during the day, and as shown in FIG. 6B, the temperature change cycle (see “t2”) during the day is 1.5 times. have. In addition, in FIG. 6A, the deviation from the target temperature (see "Tt") (see "h1") was 4 degrees Celsius in actual test results, and in FIG. 6B, the deviation from the target temperature (see "Tt") (see "h2"). ), The actual test resulted in data of 2 degrees Celsius. Therefore, according to the livestock heating system 100 according to the present invention, the temperature change and / to the deviation of the internal space 50 is much smaller than the prior art so that the stress of the chick or chicken according to the temperature change is greatly reduced, the development environment It can be seen that this is much improved compared to the prior art.

In addition, when using a hot air dryer based on the same size barn (about 330 pyeong) on the basis of the spring compared to the heating system 100 for livestock use according to the present invention, the cost of about 100 ~ 1.2 million won is reduced It can be seen that, considering the number of breeding about 14 to 16 times in one barn 10 a year, it can be seen that the cost of about 14 million to 1,200,000 won can be reduced in one barn (10).

Here, as described above, the livestock barn 10 installed with the livestock heating system 100 according to the present invention has an excellent antibacterial activity and can increase the number of annual breeding more than the conventional livestock farms, so You can increase the population. Thus, when the livestock heating system 100 according to the present invention is installed, it can be seen that the economy is very excellent.

In addition, the carbon heating member 110 in the inner space 50 can be appropriately arranged to heat the temperature variation can be reduced, and unlike the hot air dryer in the carbon heating member 110, there is no forced circulation of combustion and hot air odor Dust can be minimized. Since the temperature of the internal space 50 may be increased by heat generation and far infrared rays, the amount of oxygen consumed in the livestock house 10 may be minimized. The antibacterial effect may be improved by far infrared rays generated from the carbon heating member 110. In addition, by reducing the downtime due to bacteria disinfection, pollution prevention, etc. in the house can improve the actual operating time of the house can increase the number of animals raised annually. The failure of the carbon heating device can be reduced and the reliability can be improved.
