Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First of all, in general, a connection passage (50; connection space), such as an underground space connected to an underground parking lot or an elevator hall that connects the exterior and interior of a building, is the surface of the structure as the floor and the wall are in contact with the ground. Since the temperature distribution is lower than that of the other parts and ventilation is not performed, condensation occurs on the walls and floors, and especially in summer, when high temperature and high humidity outside air flows in, humidity even increases.

Accordingly, the condensation prevention system according to an embodiment of the present invention aims to prevent condensation occurring on the floor surface of the connection space 50, thereby preventing a safety accident for pedestrians and effectively preventing condensation. Blocking can not only solve problems related to construction defects, but also provide the effect of resolving complaints caused by inconveniences of residents of apartment houses.

2 and 3, looking at the condensation prevention system according to an embodiment of the present invention, the condensation prevention system includes a heating unit 100, a measurement unit 200, and a control unit 300. Is composed.

The heating unit 100 is buried in the bottom surface of the connection space 50 and is configured to generate heat by a control signal to increase the temperature of the bottom surface.

In detail, the heating unit 100 may be configured to include a heating coil 110, a power supply unit 120, and a power controller 130.

The heating coil 110 is buried in the bottom surface and is configured to generate heat by supplied power.

In detail, the heating coil 110 may be continuously formed on the entire bottom surface in one configuration as shown.

At this time, it is preferable that the heating coil 110 is arranged in a row on the bottom surface according to effective heating performance, maintenance and standards.

As the electric resistance increases accordingly, as the length of the heating coil 110 increases, it may be difficult to generate effective heat compared to the supplied power. If repair is required, maintenance is difficult because the entire coil must be replaced. This is because the specifications are limited.

Meanwhile, the floor surface may include a floor finishing material 10, a mortar layer under the floor finishing material 10, and an insulating layer 30 under the mortar layer 20.

The floor finishing material 10 may be applied to a well-known building floor finishing material of a parking lot or passage, and a detailed description thereof will be omitted.

The mortar layer 20 is a mixture of known cement and sand with water, and can be variously applied, such as lime mortar, asphalt mortar, resin mortar, vermiculite mortar, pearlite, etc., depending on the type of fixing material.

The heat insulating layer 30 may be variously applied to a known construction heat insulating material configuration, such as installing a heat insulating material or applying a heat insulating material.

In the structure of the floor surface described above, the heating coil 110 is installed buried in the mortar layer 20 and is preferably installed under the floor finishing material 10.

In this case, the heating coil 110 may have a different buried depth according to the configuration of the floor finishing material 10. This is because the thickness of the floor finishing material 10 is thick, or the degree to which heat generated from the heating coil 110 is transferred to the upper surface of the floor surface is different depending on the conductivity characteristics of the floor finishing material 10.

Therefore, the heating coil 110 is configured to vary the buried depth in consideration of the characteristics and thickness of the floor finishing material 10 so that effective heat generation on the floor surface can be achieved, and this buried depth is the floor finishing material 10 ) Can be designed appropriately according to the configuration and burial depth.

The power supply unit 120 serves to supply power to the heating coil 110. The power supply unit 120 may be variously applied as long as it has a configuration capable of achieving the purpose of supplying power to the heating coil 110, such as providing external commercial power or a storage battery to supply power through a storage battery.

The power controller 130 is configured to control the supply power of the power supply unit 120, and the power supply unit 120 supplies a set supply power according to a control signal received from the control unit 300, so that the heating coil 110 It is configured to control the heating temperature of.

Meanwhile, the heating unit 100 may further include an overheating prevention unit 140 connected to the power supply unit 120.

The overheating prevention unit 140 serves to prevent overheating of the heating coil 110 by blocking the supply power of the heating coil 110 when the temperature of the heating coil 110 is higher than a preset overheating temperature.

The overheating prevention unit 140 is composed of an overheating temperature sensor, and when the heating coil 110 reaches a set overheating temperature, it transmits an overheating signal to the control unit 300 so that the control unit 300 Can be configured to stop fever.

Alternatively, the overheating prevention unit 140 may be configured to stop heat generation of the radiating coil by transmitting a signal to the power supply unit 120 or the power controller 130 when the overheating temperature is set by applying a known overheating prevention fuse. If the above objectives can be achieved, various phrases can be applied.

Meanwhile, the condensation prevention system may include a drain unit 400.

3, the condensation prevention system compared to the condensation prevention system of FIG. 2, the arrangement of the heating coil 110 and other configurations except for the configuration including the drain unit 400 are substantially the same. , Hereinafter, only the configuration roughly different from the condensation prevention system of FIG. 2 will be described.

First, in the condensation prevention system, the heating coil 110 is installed in a specific area rather than the entire floor surface.

In other words, the heating coil 110 may be installed in the movement path area in which the pedestrian moves in the connection space 50 as shown. At this time, the movement path region represents an area where pedestrians mainly travel from the entrance of the connection space 50 to an exit such as an elevator entrance or an emergency stair entrance.

As described above, the heating coil 110 is installed in the movement path region, thereby ensuring the prevention of safety accidents for pedestrians, as well as reducing energy consumption to obtain an economical effect at the same time.

Furthermore, it is preferable that the heating coil 110 has a zigzag-shaped repeated coil pattern formed along the movement path region.

This is because the part where the coil pattern is formed generates heat more intensively than other parts, and generates rapid and effective heat generation, so that unnecessary energy consumption can be reduced and effective energy use can be achieved, and condensation generated in the moving path is quickly eliminated. Because it can be eliminated.

The drain unit 400 serves to condensate (condensate) water vapor in the connection space 50 with water and discharge it.

Looking at this, first of all, the connection space 50 can be viewed as a closed space, and it can be said that internal moisture is not discharged to the outside because ventilation is not properly performed.

Therefore, even if the connection space 50 removes the condensation due to the heat generated by the heating unit 100, it can be seen that the moisture of the evaporated condensation exists in the connection space 50.

That is, in the connection space 50, the relative humidity may be changed by the operation of the heating unit 100, but the absolute humidity indicating the degree of moisture contained in the connection space 50 is not changed.

If so, the condensation prevention system in such a closed connection space 50 increases the relative humidity of the connection space 50 by operating the heating unit 100, and removes condensation through it, the connection space In 50, since moisture from which condensation has evaporated remains in the connection space 50 as it is, when the operation of the heating unit 100 is stopped and the relative humidity is lowered, condensation may occur again.

Thus, the condensation prevention system, by configuring the drain unit 400 for condensing moisture in the connection space 50 and then discharging it, the absolute humidity in the connection space 50 is lowered, even after the operation of the heating unit 100 is stopped. It can be configured to prevent condensation from occurring again.

Looking in detail with respect to the drain unit 400, the drain unit 400, a drainage channel 410, a cover portion 420, a cooling module 430, a drainage power supply unit 440, and a drainage channel controller ( 450).

The drainage passage 410 is formed by forming a channel-type drainage groove 411 on the surface of the bottom surface, and is configured to drain the moisture in the connection space 50 by the cooling module 430 when condensed into water. .

Here, the drainage passage 410 is preferably formed along the wall as far as possible from the location where the heating coil 110 is located by intentionally inducing a location where moisture condenses.

This is because moisture condensation may not be effectively achieved due to residual heat of the heating coil 110, and it is difficult to overlap the heating coil 110 as the cooling module 430 is installed in the drainage passage 410 as described later. Because.

The drainage passage 410 may be formed along one side of the wall or along two sides as shown to allow water to be quickly and easily drained in a wide area, and according to the shape of the connection space 50, etc. It can be changed in various ways.

Further, the drainage passage 410 may be configured such that the bottom of the drain groove 411 is formed to be inclined so that water can easily flow downward along the slope of the bottom to be drained.

The cover part 420 is installed at the upper end of the drain groove 411, prevents foreign matters, etc. from flowing into the drain groove 411, and is buried in the drain groove 411 by the load of a pedestrian It serves to prevent the breakage of (430).

Accordingly, the cover part 420 is configured to have durability that can withstand the load of a pedestrian, and blocks the inflow of foreign substances, but is configured to form a through hole 421 so that water can be introduced.

Further, the cover part 420 may be installed on the lower surface of the insulation material 422 so as to minimize the effect of the temperature drop of the drainage groove 411 on the connection space 50 caused by the operation of the cooling module 430. have.

On the other hand, the cover portion 420, the through hole to facilitate the formation of the through hole 421 penetrating the heat insulating material 422, and to minimize the effect of the temperature drop of the drain groove 411 on the connection space 50 The shape of 421 is formed in a wavy shape as shown, but this is possible in various shapes as long as the above object can be achieved as an example, and the material can also be applied in various ways.

The cooling module 430 is configured to be cooled by supplied power.

Various configurations may be applied to the cooling module 430, and the configuration of the cooling module 430 will be described below.

First, as an example, the cooling module 430 may utilize a refrigeration cycle.

In this case, the cooling module 430 is configured to cool the drainage passage 410 by installing a refrigerant coil of an evaporator emitting cool air in the refrigeration cycle in the drainage passage 410 as shown. .

Meanwhile, although the cooling module 430 is not shown, a series of configurations including a compressor, a condenser, and an expansion valve constituting a refrigeration cycle, including the evaporator described above, may be installed in the connection space 50, and the operation of the evaporator When the compressor is operated by the supplied power, the refrigeration cycle operates.

Next, the cooling module 430 may use a thermoelectric cooling element cooled by supplied power.

The thermoelectric cooling element has a simple configuration compared to the case of using the above-described refrigeration cycle, and can provide an effect of being easy to install even if the installation space is narrow.

The thermoelectric cooling device may use a known Peltier device, and it is of course applicable to all other configurations cooled by a supplied power source.

Meanwhile, the cooling module 430 generates more condensed water where the cooling module 430 is located as moisture condenses into water from around the cooling module 430 during cooling.

Accordingly, the cooling module 430 is preferably installed in the drainage passage 410 so that the condensed water can be more easily drained. Here, reference numeral 1 denotes an entrance door, and 2 denotes an emergency door.

Referring to FIG. 4, the cooling module 430 may be buried in the bottom of the drain groove 411 so that condensed water is directly generated in the drain groove 411 and discharged effectively. However, this is an exemplary embodiment, and the cooling module 430 can be installed on the side of the drain groove 411 as well.

The drainage power supply unit 440 serves to supply power to the cooling module 430, and may supply power to the cooling module 430 through various known power supply sources.

For example, the drainage power supply unit 440 may be configured to include a storage battery and a display unit for checking the amount of power of the storage battery, so that an administrator can check the amount of power of the storage battery and replace the storage battery. Alternatively, the drainage power supply unit 440 may receive power by connecting to a supply line of commercial power of a building.

The drainage channel controller 450 serves to control the supply power of the drainage channel power supply unit 440, and allows the drainage channel power supply unit 440 to supply the set supply power according to a control signal received from the control unit 300, thereby cooling The cooling temperature of the module 430 can be controlled.

Meanwhile, the drainage power supply unit 440 and the drainage controller are preferably embedded in the wall, and may be integrated with the power supply unit 120 and the power controller 130 of the heating unit 100.

Hereinafter, the measurement unit 200 will be described.

The measurement unit 200 is installed in the connection space 50 to measure the presence of condensation in the connection space 50 and is configured to transmit a measurement value to the control unit 300.

Looking at the measurement unit 200 in detail, first, the measurement unit 200 may be configured to include a humidity sensor (210).

The humidity sensor 210 is configured to measure the humidity of the connection space 50 and transmit the humidity value of the connection space 50 to the control unit 300.

Here, the humidity sensor 210 may be installed on a wall having a set height from the bottom surface, but is not limited thereto as long as it can measure the humidity value of the connection space 50.

On the other hand, the measuring unit 200 includes an air temperature sensor 220 and a floor temperature sensor 230 in addition to the humidity sensor 210 described above so as to more effectively and accurately measure whether or not condensation occurs on the floor surface. It can be configured.

The bet temperature sensor 220 is installed in the connection space 50 to measure the temperature of the connection space 50 and transmits the measured temperature value of the connection space 50 to the control unit 300.

The floor temperature sensor 230 is buried in the floor surface, measures the temperature of the floor surface, and transmits the measured floor surface temperature value of the connection space 50 to the controller 300.

Here, since the floor temperature sensor 230 may be exposed to the risk of damage due to pedestrians, etc. as it is installed on the floor surface, it is necessary to provide a space where pedestrians do not usually walk or a separate installation space in consideration of this. have. Accordingly, the floor temperature sensor 230 is buried in the channel-type drainage groove 411 of the drainage passage 410 to be described later, thereby preventing damage and reducing the hassle of forming a separate installation space. .

The control unit 300 is configured to receive a measurement result from the measurement unit 200 and transmit a control signal to the heating unit 100.

In detail, the control unit 300 receives measured values from each of the humidity sensor 210, the internal air temperature sensor 220, and the floor temperature sensor 230, as shown in FIG. It is configured to determine whether there is condensation on the floor and transmit a control signal to the heating unit 100 and the drain unit 400.

The control unit 300 may be installed embedded in the wall of the connection space 50 and configured to transmit a control signal to the heating unit 100 and the drain unit 400 through wireless communication or wired communication.

Hereinafter, various control methods of the controller 300 through the measurement unit 200 will be described with reference to FIGS. 6 to 8.

(Example 1)

In the case of the first embodiment, the measurement unit 200 includes a humidity sensor 210, and the controller 300 calculates the humidity value of the connection space 50 obtained through the humidity sensor 210. It is configured to determine whether there is condensation on the bottom surface based on this, and to remove condensation by heating the heating unit 100 through this.

Referring to FIG. 6 in detail, first, the controller 300 receives the humidity value and the temperature value of the connection space 50 through the humidity sensor 210 and the air temperature sensor 220 (S10).

In this case, the control unit 300 may be configured to receive a humidity value and a temperature value according to a set time interval to recognize the humidity and temperature state of the connection space 50 in real time.

When receiving the humidity value and the temperature value of the connection space 50 in the above, the control unit 300, through the humidity value measured from the humidity sensor 210 and the temperature value measured from the air temperature sensor 220 The relative humidity value of the connection space 50 is calculated.

Here, the measurement unit 200 may be configured to include a humidity sensor 210 and an air temperature sensor 220 in order to calculate the relative humidity value of the connection space 50 as described above. It goes without saying that the relative humidity of the connection space 50 can be measured using a known thermo-hygrometer capable of measuring humidity.

When the relative humidity value of the connection space 50 is calculated in this way, the control unit 300 determines whether the relative humidity value of the connection space 50 is greater than or equal to the set heat generation drive value (S20), and the relative humidity value of the connection space is If it is more than the set heating drive value, the heating unit 100 is controlled to generate heat (S30).

Here, the heating drive value is a relative humidity value that is judged to have a high probability of condensation or condensation on the bottom surface, and refers to a relative humidity value that requires the operation of the heating unit 100, and is a relative humidity in which condensation may occur. Although it can be set based on the humidity value of 85%, this can be changed according to the volume and season of the connection space 50 as an example.

On the other hand, the control unit 300 controls the operation of the heating unit 100 to stop when a set condition is met after driving control of the heating unit 100. This is to reduce energy consumption by preventing unnecessary driving of the heating unit 100 by stopping the operation of the heating unit 100 when the condensation on the bottom surface is removed, thereby obtaining an economical effect.

Hereinafter, a control related to stopping the operation of the heating unit 100 of the control unit 300 will be described.

The control unit 300 may control the heating unit 100 to stop heating by a set heating stop value.

That is, the control unit 300 controls the heating unit 100 to stop heating when the relative humidity value of the connection space 50 becomes less than or equal to the heating stop value after heating of the heating unit 100 (S40).

Here, the heating stop value may be set as a relative humidity value of the connection space 50 that can be determined that condensation on the bottom surface has been sufficiently removed.

Further, the heat generation drive value may be set to be equal to or greater than the heat generation stop value, and at this time, the difference between the heat generation drive value and the heat generation stop value may be removed even when condensation is generated based on the relative humidity. It is preferable to set it as the difference between the relative humidity judged to be there.

On the other hand, the control unit 300, when the temperature of the heating coil 110 is higher than the overheating limit value in order to limit the abnormal heat generation of the heating coil 110 and prevent the risk of accidents such as fire and electric leakage, the heating unit 100 The process of controlling to stop the heat generation of may be additionally performed (S50, S60).

(Example 2)

The second embodiment is an embodiment in which the condition for stopping the heat generation of the heating coil in the above-described first embodiment is different, and the heating stop condition of the heating coil 110 is a bottom surface temperature value other than the above-described heating stop value. This is an embodiment when considering

Therefore, in the case of the second embodiment, the measurement unit 200 includes a humidity sensor 210 and an air temperature sensor 220 as well as a floor temperature sensor 230.

Referring to FIG. 7, first, the controller 300 periodically receives the humidity value and the temperature value of the connection space 50 from the humidity sensor and the air temperature sensor 220 (S10).

Then, the control unit 300 calculates the relative humidity value of the connection space 50 through the humidity sensor 210 and the air temperature sensor 220, and at this time, the relative humidity value of the connection space 50 is set. It is determined whether it is more than the driving value (S20).

At this time, when the relative humidity value of the connection space 50 is less than the heating drive value, the control unit 300 periodically receives the humidity and temperature of the connection space 50 to continuously check the environmental state of the connection space 50. .

On the other hand, if the relative humidity value of the connection space 50 is greater than or equal to the set heating drive value, the control unit 300 determines that condensation has occurred on the floor surface, and the heating unit 100 may remove the condensation from the floor surface. ) Is controlled to generate heat (S30).

On the other hand, as described above, when the heating coil 110 generates heat, the floor surface is heated to increase the temperature, and the control unit 300 predicts that condensation on the floor surface is removed based on the temperature of the floor surface. The operation of the heating coil 110 can be controlled.

Looking at this in detail, the control unit 300 periodically receives the temperature value of the floor surface from the floor surface temperature sensor 230, and whether the rise value of the floor surface temperature after the heating of the heating coil 100 becomes more than the reference value. It is determined (S40). Here, the comparison of the floor temperature rise value and the reference value may be controlled with a table sheet in which a reference value is set in consideration of an efficient surface.

In this way, after comparing the floor temperature rise value and the reference value, when it is determined that the floor temperature rise value is greater than or equal to the reference value, the control unit 300 controls the heating coil 110 to stop operating (S60).

Here, the floor temperature rise value is a range value in which the temperature of the floor surface is increased by a certain range from the initial state as the floor surface is heated, and the difference between the current temperature value from the temperature value measured when the heating coil 110 starts It is calculated and calculated, and the state in which the rise of the floor temperature is equal to or higher than the reference value refers to a state in which it can be determined that the floor surface is sufficiently heated to remove condensation from the floor surface.

In addition, the reference value is a value that can be determined that condensation has been removed from the bottom surface of the connection space 50 by the rise in the floor temperature (rise width), and the season or the temperature of the connection space 50, the floor material and volume The value can be set differently in consideration of, etc.

As described above, in the second embodiment, the control unit 300 determines that condensation has occurred on the floor surface when the relative humidity value of the received connection space exceeds the set heating drive value, and controls the heating coil 110 to generate heat. However, when the floor surface temperature raised by the heating coil 110 is higher than the reference value, the heating coil is controlled to stop heating.

On the other hand, in the above, the control unit 300 is configured to heat-control the heating unit in consideration of the relative humidity of the connection space 50, but in another embodiment, the dew point temperature of the connection space 50 and the The heating unit can be controlled in consideration of the floor temperature.

Looking at this, the controller 300 receives a temperature value and a humidity value of the connection space 50 through the internal air temperature sensor 220 and the humidity sensor 210, and determines the dew point temperature of the connection space 50. Each is calculated.

Here, in the calculation of the dew point temperature, the actual amount of water vapor in the connection space 50 is calculated according to Equation 1 below, and the dew point temperature for the calculated amount of actual water vapor is calculated. At this time, the amount of saturated water vapor according to the temperature is obtained through the saturated water vapor amount table, and the dew point temperature for the calculated actual water vapor amount is obtained through the dew point calculation table.

(Equation 1)

Thereafter, the control unit 300 compares the temperature of the floor surface measured through the floor surface temperature sensor 230 with the dew point temperature, and if the floor surface temperature is less than the dew point temperature, it is determined that condensation has occurred on the floor surface. In general, the condensation phenomenon means a wet state generated by saturated water vapor in the air, and the air (saturated water vapor) containing water vapor in the connection space 50 is the bottom surface at a temperature equal to or lower than the dew point temperature. This is because water droplets form on the low-temperature bottom surface as the temperature decreases when contacted with.

If the temperature of the bottom surface is less than the dew point temperature of the connection space 50, the control unit 300 determines that condensation has occurred on the bottom surface and controls the heating coil 110 to heat to remove the condensation on the bottom surface. Do it.

(Third Example)

The third embodiment includes the drain unit 400 described above in the condensation prevention system, and controls the operation of the drain unit 400 after the heating coil 110 of the first embodiment or the second embodiment stops heat generation. It relates to an example.

Here, the drain unit 400 is a configuration for lowering the absolute humidity of the connection space 50 by discharging moisture in the connection space 50 as described above, and in looking at the control configuration of the drain unit 400 Previously, it is necessary to examine the state of the connection space 50 after the heating coil 110 is stopped.

Looking at this, first, the connection space 50, as described above, because pedestrians do not frequently enter and exit, and the opening and closing doors are also briefly opened when entering, so that the connection space 50 can be regarded as a closed space. .

Therefore, the connection space 50 in this state after the operation of the heating coil 110 is stopped, the relative humidity is increased by heating of the heating coil 110, but the moisture from which condensation evaporates is in the connection space 50. Since it remains the same, it can be said that the absolute humidity has not changed.

Therefore, when the temperature of the connection space 50 is lowered after the heating coil 110 is stopped, the relative humidity of the connection space 50 decreases again, and moisture in the connection space 50 that cannot be discharged is again on the floor. There may be condensation.

Thus, the condensation prevention system according to the third embodiment, by operating the drain unit 400 when the operation of the heating unit 100 is stopped to discharge moisture in the connection space 50, the absolute of the connection space 50 It is constructed to reduce humidity and fundamentally prevent condensation on the floor.

Looking at the configuration and control of the drain unit 400 with reference to FIG. 8, the control unit 400 controls the cooling module 430 to operate when the heating unit is stopped (S60) (S70). .

When the cooling module 430 is operated in this way, the cooling module 430 is rapidly cooled, and the moisture in the drainage groove 411 is condensed and discharged by locally cooling the temperature of the drainage passage 410 in which the cooling module 430 is buried. As a result, it is possible to bring about an effect of lowering the absolute humidity of the entire connection space 50.

As described above, when moisture in the connection space 50 is condensed into water and discharged by the operation of the cooling module 430, the moisture content of the connection space 50 decreases and the absolute humidity of the connection space 50 is also lowered. Thus, even if the temperature of the connection space 50 decreases and the relative humidity value increases, it is possible to prevent recurrence of condensation on the floor surface.

Meanwhile, the control unit 300 prevents excessive condensation of moisture in the connection space 50 and stops the operation of the cooling module 430 according to a set condition so that effective energy consumption of the drain unit 400 can be achieved. Control.

Looking at this, first, the control unit sets the setting condition as the driving time of the cooling module 430, and when the driving time of the cooling module 430 is greater than the set value (S80), the operation of the cooling module 430 is It can be controlled to stop (S100).

Here, it is preferable to set the driving time setting value of the cooling module 430 as a time value until the temperature change of the connection space 50 is affected by the cooling of the cooling module 430. This is because when the indoor temperature of the connection space 50 is lowered by the driving of the cooling module 430, the effect of the heating coil 110 is canceled.

That is, the set value for setting the driving time of the cooling module 430 is that only the temperature of the drainage channel 410, which is a specific space, is lowered to locally cool the temperature around the drainage channel 410 to condense and discharge moisture. The temperature of the connection space 50 may be unaffected, and may be set to a value capable of lowering the absolute humidity of the connection space 50 as a whole.

On the other hand, although not shown, even if the driving time of the cooling module 430 is less than the above-described setting value, the control unit 300 controls the driving of the cooling module 430 by referring to the change in the relative humidity of the connection space 50. Can be controlled.

This is, under the condition that the cooling module 430 does not affect the temperature of the connection space 50, when the relative humidity value of the connection space 50 is sufficiently low below the cooling stop value, the cooling module 430 This is because even if the driving time does not elapse for a long time, it can be determined that the occurrence of condensation on the floor does not recur.

Here, when the heating unit 100 is stopped, the relative humidity value of the connection space 50 is configured to have a higher value than the relative humidity value of the connection space 50 when the cooling module 430 is stopped. It is desirable. When the cooling stop value is equal to or higher than the heat generation stop value or the reference value, the operation of the heating unit 100 and the cooling module 430 collide with each other, thereby limiting the efficiency of the condensation prevention system according to the present invention. Because there is.

On the other hand, for setting the relative humidity value of the above cooling stop value and heat generation stop value, for example, it is assumed that the relative humidity is 50%, which can be considered an appropriate humidity condition without humidity, and when condensation occurs, the relative humidity is 85%. In this case, the heating drive value is set to a relative humidity value of 85% or more at which condensation can occur, and the heating stop value and the driving of the cooling module 430 are 70% of the corresponding relative humidity that can be determined that condensation has been removed. It is set below, and the cooling stop value of the cooling module 430 may be set to a relative humidity of 50% or less.

According to the above, the condensation prevention system reduces the relative humidity of the connection space by the heating unit 100 as well as the absolute humidity of the connection space 50 through the drain unit 400 to reduce condensation on the floor surface. It can be prevented at the source.

The present invention has been described with reference to the embodiments shown in the drawings, but these are merely exemplary, and those of ordinary skill in the art will appreciate that various modifications and equivalent other embodiments are possible therefrom.
