In particular, it would have an excellent effect if it is installed on the road surface 10 of a region where it is difficult for a manager to cope quickly due to sudden weather changes such as a rare mountainous area, a wide field, and a road on a bridge.

At the same time, even in urban areas, roads can always be frozen in cold weather in the shaded areas, which prevents road surface freezing, or in the case of urban areas, it is difficult for a midnight manager to respond quickly. In addition, there is an excellent advantage, such as to prevent the freezing of the road due to sudden temperature changes even by the external temperature detection or control of the control room that can control the entire city.

The detailed configuration for this is as follows.

It is to produce a photovoltaic device 31 for supplying power to the geothermal heat exchange power supply device 30 side.

And look at the detailed configuration of the geothermal heat exchanger 20 receives the power from the geothermal heat exchange power supply 30 side as follows.

That is, the geothermal heat exchanger 20 includes a signal transmitter / receiver 22 which transmits and receives a signal with the geothermal heat exchanger power supply 30; A geothermal hot water temperature sensor 231 for detecting a temperature of geothermal hot water; A heated hot water temperature sensor 232 which detects the temperature of the anti-freeze water which is heated and supplied to the road temperature heat pipe 41; A heated hot water flow sensor 233 for detecting a flow of frost protection water supplied to the road heating pipe 41; A heat exchange operation unit 25 for raising the temperature of the frost preventing water by using the heat source supplied through the geothermal source pipe 21; Heat exchange control unit 241; Heat exchange memory unit 242; The heat exchange power receiver 243 is included.

In addition, the road freezing prevention device (A) according to the present invention provided as described above, the road heating hot water valve device 40, the photovoltaic device 31 and the wind power generator 32 that can be installed on a plurality of roads And a plurality of devices, such as a geothermal heat exchanger power supply device 30 that receives electric power from a general electric power source 33, a geothermal heat exchanger device 20 that provides anti-icing water to the road heating / hot water valve device 40, and the like. It may be provided with a control unit 50 of the control unit for the user to check the operating state connected to the.

Therefore, together with the control device 50, the road heating hot water valve device 40, the geothermal heat exchange power supply 30, the geothermal heat exchanger 20 may be provided to transmit and receive signals with each other.

Thus, the control device 50 may be provided with a display 51 for the user to watch, and a signal input and output unit 52 for transmitting and receiving signals to and from other devices, and also weather conditions such as external temperature and humidity. The meteorological sensing device 53 and the control controller 54 for detecting the situation may be provided.

That is, the geothermal heat exchanger 20 may be provided with a signal transmitter / receiver 22 that transmits and receives the geothermal heat exchange power supply device 30, the road heating and hot water valve device 40, and the controller 50. There will be.

In addition, the geothermal hot water temperature detection sensor 231 for detecting the temperature of the geothermal hot water supplied through the geothermal source pipe 21 may be provided. Therefore, it detects the temperature of geothermal hot water supplied from the ground. In general, geothermal heat is about 10 ~ 15 ℃, so if it is difficult to use because it is lower than this temperature or if it is too hot, the ground state has changed to an abnormal state. It may be controlled to switch to an emergency alert so that it can be taken.

And a heated hot water temperature sensor 232 for detecting the temperature of the anti-freeze water is heated to be supplied to the road heating pipe 41 side may be provided, the flow of the anti-freeze water supplied to the road heating pipe 41 side The heating hot water flow sensor 233 to detect may be provided. Therefore, it is to supply the anti-freezing water having a normal temperature and pressure to the road heating pipe 41 side of the road heating hot water valve device (40). At this time, the appropriate temperature of the anti-freeze water may be set according to the temperature or weather conditions of the external environment according to the natural environment and season of the region.

Winter temperatures in Korea are generally around 0 to -20 degrees Celsius in general areas. On the other hand, when it is supplied at about 50 to 70 degrees Celsius, the appropriate temperature for the freezing water prevents the road surface (10) of the road. This may be prevented.

Of course, when it is very cold in the middle of winter, such as mountainous areas, it can go down to less than -25 degrees Celsius, and even if the length of the road heating pipe 41 embedded in the road surface 10 becomes long, it provides a higher temperature freezing water. It may be arranged to. Therefore, it can be prepared to supply ice freezing water of suitable conditions according to various weather conditions such as colder regions or warmer regions than Korea.

In this way, a switching device for allowing the geothermal source supplied from the geothermal source pipe 21 embedded in the ground to heat the anti-icing water may be further added. That is, the heat exchange operation unit 25 is provided to increase the temperature of the icing preventing water by using the heat source supplied through the geothermal source pipe 21.

The heat exchange operation unit 25 is to transfer the energy of the geothermal source to the ice freezing water by the principle of the heat pipe.

That is, the heat exchange operation part 25 is provided with a heat exchanger part 26 to allow the freezing prevention water to be heated to an elevated temperature using the heat source through the geothermal source pipe 21.

In addition, the heating heat exchange part 26 includes an endothermic part 261 that exchanges heat with the geothermal source heat exchange part 211 connected to the geothermal source pipe 21; A temperature increasing compressor 262 compressing the heating solvent flowing through the heat absorbing portion 261 to obtain a high temperature; A heat dissipation unit 263 for generating heat from a high temperature heating solvent supplied from the temperature increasing compressor 262; A heating expansion part 264 for causing the heating solvent from which heat is released from the heat dissipation part 263 to expand before the heat absorbing part 261; It is connected to the tunnel heating pipe 41 is provided with a heating unit 265 and the like to prevent the freezing water to radiate heat radiated from the heat radiating portion 263.

That is, the geothermal hot water supplied through the geothermal source pipe 21 flows through the geothermal source heat exchanger 211 on one side, and the pipe circulation structure includes the geothermal source pipe 21 and the geothermal source heat exchanger 211. It is arranged to continue to flow through. Thus, the geothermal hot water passing through the geothermal source pipe 21 buried in the ground absorbs heat from the ground, and the geothermal hot water absorbed in this way is radiated from the geothermal source heat exchanger 211 and the heat of the heat exchanger 26. It may be prepared to transfer the heat energy to the heat absorbing portion (261) side.

Similarly, the heated solvent passing through the heat absorbing portion 261, the temperature increasing compressor 262, the heat dissipating portion 263, the heat expanding portion 264, and the like on the heating heat exchange part 26 is continuously circulated and flows in the circulation pipe structure. It is prepared to.

Thus, the heat energy generated from the geothermal source heat exchanger 211 through which the geothermal hot water flows is absorbed by the temperature rising solvent passing through the heat absorbing portion 261. On the contrary, the heat energy of the temperature rising solvent passing through the heat radiating portion 263 is radiated and provided together. The heat energy is to be delivered to the anti-freezing water side inside the heating unit 265.

Therefore, the ground heat energy absorbed through the geothermal source pipe 21 is provided so that the heat energy is transferred to the anti-icing water side through the heat heat exchanger 26 of the geothermal heat exchanger 20.

In particular, the geothermal hot water supplied through the geothermal source pipe 21 may be supplied at a lower temperature than the anti-icing water.

Accordingly, when the temperature rising solvent passing through the heating expansion part 264 is in a low temperature state, the thermal energy of the geothermal heat exchanger 211 passing through the geothermal hot water is absorbed to heat the low temperature rising solvent.

Thereafter, the temperature rising solvent passes through the temperature increasing compressor 262 and undergoes a compression process, thereby heating the temperature to a higher temperature. Thus heated heating solvent is provided to radiate heat through the heat dissipation portion 263, the heat energy emitted from the heat dissipation portion 263 is absorbed by the anti-freezing water passing through the heat riser 265, the road surface ( 10).

In addition, the temperature rising solvent in which the heat energy is discharged from the heat dissipation unit 263 is to be recirculated to absorb the heat of geothermal hot water again in the state in which the heat expansion unit 264 is expanded at low pressure.

In addition, the heat exchange operation unit 25 of the geothermal heat exchanger 20 may be provided with a cold heat exchanger 27 to lower the temperature together with the heat exchanger 26 that operates to increase the temperature from the geothermal source. That is, in the cold / hot heat exchanger 27 which receives the heat of the ground through the geothermal source pipe 21, the cold / hot solvent may be provided at a low temperature. That is, in a hot summer season, room temperature may be more than 25 degrees Celsius, or worse, about 40 degrees Celsius. Therefore, it may be provided to lower the temperature of the cold and hot solvent by heat exchange from the geothermal hot water of about 10 to 15 degrees Celsius supplied from the ground.

That is, the summer air conditioner may allow the indoor temperature or the temperature of the refrigerator to be low depending on the amount of heat released from the internal outdoor unit to the outside, but the efficiency of the outdoor unit may be reduced because the summer outdoor temperature is high.

Thus, when the heat exchange is performed between the geothermal hot water and the high temperature cold solvent supplied at a temperature lower than the external temperature during the summer, a more efficient cooling device and outdoor unit may be provided.

That is, the geothermal cooling heat exchanger 212 may be provided to supply the geothermal hot water to the vicinity of the cold / hot heat exchanger 27 to allow heat exchange.

The cold / hot solvent passing through the cooling compressor 272 is supplied to the cooling unit 273 of the cold / hot heat exchange unit 27 adjacent to the geothermal cooling heat exchange unit 212 in a state of high temperature and high pressure. Therefore, since the heat energy of the high temperature and high temperature cold solvent is to be released to the geothermal cooling heat exchange unit 212 side which becomes relatively low temperature, the cold and hot solvent passed through the cooling unit 273 by such heat exchange is a low temperature.

After that, the cooling expansion unit 274 expands the cold / hot solvent so that the coolant is further cooled. By the low temperature section 271 through which the low-temperature cold solvent passes, the coolant supplied to the indoor cooling device 276 or the refrigerator is cold / hot part 275. ) Is a low temperature. Therefore, the indoor unit or the refrigerator can be more effectively cooled by the cold / hot heat exchanger 27 which forms a low temperature compared to the outside temperature of the hot summer.

In addition, a general solvent suitable for heat exchange in low temperature characteristics, high temperature characteristics, thermal expansion, and the like may be used for the anti-freezing water flowing in the geothermal source pipe 21, the elevated temperature solvent of the heat exchange part 26, and the cold solvent of the cold heat exchange part 27. It can be.

Thus, in the heat exchange operation part 25 of the geothermal heat exchanger 20 which receives heat energy from a geothermal heat source, the heat exchanger part 26 for heating to higher temperature, and the cold / hot heat exchange part 27 for cooling to low temperature are shown. Etc. can be provided. Therefore, the cold / hot heat exchanger 27 provides an environment in which a low temperature such as a cooling device and a refrigerator is to be maintained. In addition, as described above, by the heat-heat exchanger 26, the road of the shade in the winter, the ground 111 of the entrance and exit of the tunnel 11, the road on the bridge 12, etc. are easily frozen or once different from other areas. When frozen, there is a risk of slipping of the car is not easily melted, the road heating hot water valve device 40 and the road heating pipe 41 according to the present invention is buried in order to prevent freezing in such areas, such road heating The heating heat exchange part 26 is provided to heat the anti-icing water supplied to the pipe 41.

That is, in winter, warm hot water supplied through the heat exchange unit 26 of the heat exchange operation unit 25 is supplied to the geothermal source pipe 21 of the road surface 10 to prevent freezing and to supply heating water to the control center. In the meantime, the refrigerator or the like may be provided by a cold refrigerant supplied by the cold / hot heat exchange unit 27.

In addition, on the other hand, it is not necessary to prevent freezing of the road in summer, but in a cold place in the mountainous region, it may be used as a bath water or hot water by using hot water supplied through the heat exchanger 26 of the heat exchange operation unit 25. While being there, it may be provided to operate the refrigerator or cool the room of the control center by the coolant that can be supplied through the cold / hot heat exchange unit (27).

Thus, the road heating hot water valve device 40 is provided to receive the anti-freezing water supplied from the geothermal heat exchange device 20 to the road heating pipe 41, and the road heating hot water valve device 40 is provided. The road valve operation part 43 may be provided to be opened and closed according to the temperature value detected from the external temperature sensor 42.

And, the valve control unit 46 may be included together.

Thus, if it is detected that the outside temperature of the region is low, it may be able to send a request signal to send the icing water prevented the hot water to the geothermal heat exchanger (20) side. In addition, the road valve operation unit 43 may be operated to be provided with the anti-freezing water to the road heat pipe (41).

In addition, with respect to the road heating pipe 41 to prevent the freezing water to flow on the road surface 10, the discharge pipe 411 side to flow from the road valve operating portion 43 to the road heating pipe 41 side, and the road The inlet pipe 412 side is provided to flow from the heat pipe 41 side to the road valve operation portion 43 side. The discharge pressure sensor 413 for measuring the pressure of the anti-freeze water discharged to the discharge pipe 411 side is provided, and also the inlet pressure sensor for measuring the pressure of the anti-freeze water flowing into the inlet pipe 412 side ( 414 may be provided together.

Thus, the valve control unit 46 compares the data values of the flow pressure of the anti-icing water transmitted from the discharge pressure sensor 413 and the inflow pressure sensor 414, and if the comparison pressure is similar, the valve is determined to be in a normal state. . On the other hand, when the inflow pressure is lower than the discharge pressure of the anti-freeze water, it is determined that an abnormal state occurs in the flow of the anti-freeze water, such as when the road heating pipe 41 is damaged or the middle of the pipe is blocked. Therefore, when such an abnormal condition occurs, the anti-icing water may be discharged to the outside indefinitely, whereas if the pipe is blocked, there is a risk that the pumps are overloaded, the road valve operation unit 43 to block the flow of the anti-icing water Will be controlled.

Along with this, a signal for occurrence of an abnormal state may be transmitted to the geothermal heat exchanger 20 to adjust the flow rate of the icing water or to stop the supply. In addition, the control device 50 may be provided to transmit a data signal for the abnormal state, so that the user can take action.
