Description

TECHNICAL FIELD [0001] The present invention relates to a condensation control method using a condensation prevention system for a building,

The present invention relates to a dew condensation control method using a dew condensation prevention system of a building, and more particularly, to a dew condensation control method using a dew condensation prevention system for a building that detects occurrence of condensation of a building and removes condensation generated in the building.

When the temperature of the wall and the temperature of the air in contact with the wall are large, the moisture in the air is condensed on the cold wall surface and dew is formed on the surface. This is called condensation phenomenon.

The condensation phenomenon occurs not only in the cold winter season but also in the hot summer season. Therefore, when the hot air in the room touches the inner surface of the outer wall body whose temperature is lowered by the cold outside air in winter, Condensation occurs, and condensation occurs in the hot summer season. The condensation phenomenon occurs in the inner wall of the outer wall corresponding to an underground structure such as an underground parking lot or a basement.

At this time, the condensation phenomenon of the hot summer is that when the hot inside air touches the cold underground outer wall, the moisture in the hot air condenses on the cold wall to generate condensation. These condensation phenomena cause molds inside the building to harm the health of the residents and damage the beauty of the residents, resulting in inconvenience.

In order to prevent the dew condensation that occurs even in the cold winter season as well as the hot summer season, a method of installing a heat insulating material on the wall surface has been used so that the hot air including a lot of moisture does not directly touch the cold wall.

However, even if insulation is applied to the surface of the wall, it is not satisfactory to fundamentally block the condensation phenomenon, and it is difficult to remove the condensation caused by the condensation phenomenon.

The boiler part 120 may include a general heating boiler and may be separately included for hot water injection for removing condensation. Of course, in the case of a building heating by the central heating system, the hot water supplied from the central heating system without the boiler part 120 may be injected into the tube pipe 132 through the valve 125.

The tube tube portion 130 is a portion buried in the bottom and wall of a region where condensation frequently occurs or a region where condensation should be removed, and includes a support 131 and a tube tube 132 as shown in FIG. 1B And a tube tube 132 may be installed along the support table 131 at regular intervals.

As shown in FIG. 1C, the condensation detection sensor unit 140 is mounted on a wall inside the building, and includes a first temperature sensor (not shown) for measuring the temperature of the wall surface, A second temperature sensor (not shown), a first hygrometer (not shown) for detecting the humidity inside the building, and a second hygrometer (not shown) for detecting the humidity of the wall surface.

The condensation detection sensor unit 140 is connected to the control unit 110 by wire or wireless, and detects the temperature of the wall surface, the temperature of the air inside the building, the humidity inside the building, and the humidity of the surface of the wall in real time, To the control unit 110. Here, when the dew condensation sensor unit 140 is wirelessly connected to the controller 110, the dew condensation sensor unit 140 may be connected by a short-range wireless communication method such as Bluetooth, ZigBee, or WiFi.

That is, the control unit 110 determines whether the temperature of the wall surface is a dew point temperature or a temperature lower than the dew point temperature with respect to the internal air temperature of the building, (II) the temperature of the wall surface, Whether there is a difference between the temperature difference between the temperature and the condensation occurrence temperature difference, and (III) whether the humidity of the wall surface exceeds the condensation occurrence threshold value with respect to the indoor air temperature of the building. can do. Here, the dew point temperature is defined as the temperature at which air vapor is saturated and dew is formed as the air temperature is lowered at a constant pressure. This dew point temperature is proportional to the amount of water vapor, i.e., humidity.

FIG. FIG. 2 is a flowchart for explaining a dew condensation control method according to another embodiment of the present invention, and FIG. 3 is a psychometric chart for explaining a dew condensation control method according to another embodiment of the present invention.

The dew condensation control method according to another embodiment of the present invention detects whether condensation has occurred in response to the condensation detection information received from the condensation detection sensor unit 140 in real time at step S210.

That is, the controller 110 controls the temperature of the wall surface detected by the first temperature sensor, the second temperature sensor, the first hygrometer and the second hygrometer of the dew condensation sensor unit 140, the air temperature inside the building, And the humidity of the surface of the wall are received by the wired or wireless communication. Here, the wireless communication may employ a short-range wireless communication method such as Bluetooth, ZigBee, or WiFi.

At this time, the control unit 110 determines whether condensation has occurred using the condensation detection information received from the condensation detection sensor unit (S220).

That is, the controller 110 uses the condensation detection information including the temperature of the wall surface, the temperature of the internal air of the building, the humidity inside the building, and the humidity of the wall surface received from the condensation detection sensor unit 140, (II) whether the temperature difference between the wall surface temperature and the building's internal air temperature is greater than or equal to the difference And (III) whether the humidity of the wall surface exceeds the condensation occurrence threshold value with respect to the internal air temperature of the building, it is judged that condensation occurs.

Specifically, the conditions for determining whether the surface temperature of the wall surface relative to the internal air temperature of the building has a dew point temperature or a temperature lower than the dew point temperature can be determined by using the table relating to the dew point temperature described in the following [Table 1] The temperature of the wall surface received from the detection sensor unit 140, the temperature of the inside air of the building and the humidity inside the building are calculated so that the temperature Ts of the wall surface is the dew point temperature Tc described in [Table 1] It can be judged whether or not the temperature is lower than the temperature Tc.

For example, as shown in the moisture diagram shown in Fig. 3, the dry bulb temperature related to the room temperature is determined from the "A" of 25 DEG C to the point where the relative humidity calculated using the humidity inside the building reaches 50% , Find the point where the relative humidity is 100%, and check the temperature "B" at that point. At this time, when the temperature of the room wall surface of the house having the room temperature of 25 ° C is directly lowered to about 13.3 ° C as the dew point temperature (Tc), dew condensation occurs on the surface of the room wall surface.

Accordingly, when the temperature Ts of the wall surface as shown in the following formula (1) is the dew point temperature Tc described in [Table 1], or the temperature becomes lower than the dew point temperature Tc, It is determined that condensation has occurred.

(Ⅱ) The condition for judging whether the temperature difference between the wall surface temperature and the internal air temperature of the building differs by more than the condensation temperature difference is, for example, when the internal air temperature of the building having a relative humidity of 40% When a temperature difference of 18 ° C occurs between the temperature of the wall surface and the temperature of the inside air of the building in the case of a temperature of 7 ° C, the temperature of the wall surface at 9 ° C is 9.5 ° C in the humidity chart shown in Table 1 and Fig. Lt; RTI ID = 0.0 > dew point < / RTI > temperature. As a result, the temperature of the wall surface has a temperature lower than the dew point temperature, so that condensation occurs.

That is, the dew condensation temperature difference T _d represents a temperature difference between the relative humidity and the dew point temperature Tc on the basis of the air temperature Ti inside the building in the following equation (2). It is shown that condensation occurs when the condensation occurring temperature difference T _d is smaller or equal to the temperature difference between the air temperature T _i inside the building and the temperature Ts of the wall surface as shown in the following equation .

According to the judgment condition of the condensation occurrence temperature difference, whether or not condensation has occurred is detected by detecting whether the temperature of the wall surface has a temperature difference of 15.5 DEG C or more with respect to the relative humidity of 40% and the air temperature inside the building at 25 DEG C in the example described above.

(Ⅲ) Regarding the internal air temperature of the building The judgment condition of whether the humidity of the surface of the wall exceeds the condensation occurrence threshold is a condition that the moisture is concentrated on the wall surface due to condensation, will be.

For example, the humidity of the surface of the wall detected through the second hygrometer of the dew condensation sensor unit 140 has a range of 70 to 75% with respect to the air temperature inside the building at room temperature. Accordingly, if the humidity of the wall surface is detected to be in the range of 70 to 75% with respect to the air temperature inside the building at room temperature, condensation has started to occur. Of course, the condensation occurrence threshold may vary depending on the air temperature inside the building.

Then, the control unit 110 injects hot water into the tube pipe 132 of the condensation occurrence area to circulate the hot water to remove condensation generated in the condensation area (S230).

The control unit 110 operates the boiler unit 120 including a boiler or a general heating boiler for hot water injection to open and close the valve 125 for commercial hot water supplied from the supplied hot water or central heating system To the tube tube 132,

The hot water injected into the tube pipe 132 circulates along the tube pipe 132 and can radiate heat to the floor and the wall of the building where the condensation has occurred, thereby evaporating the condensation generated in the form of water vapor. As a result, condensation on the floor or wall of the building can be removed and the amount of water vapor can be increased against the air inside the building in the form of water vapor.

During the process of injecting hot water into the tube pipe 132 of the condensation occurrence area, the controller 110 determines whether the condensation has been removed by removing the condensation in the condensation area by the three characteristics of determining whether condensation has been removed (S240).

Here, three characteristics for determining whether or not to remove condensation are (1) whether the wall surface temperature is higher than the dew point temperature, (2) whether the wall surface temperature is higher than the building internal air temperature Whether the temperature difference is within the condensation occurrence temperature difference, and (3) whether the internal humidity of the building exceeds the condensation removal threshold. If any one of these three characteristics is satisfied, the controller 110 can determine that the condensation in the area where the condensation has occurred is eliminated and the condensation phenomenon is eliminated.

Specifically, (1) a characteristic that the temperature Ts of the wall surface with respect to the internal air temperature Ti of the building has a temperature higher than the dew point temperature Tc can be expressed by the following equation (4).

This is because the temperature of the wall surface is raised by the heat transferred to the floor and the wall by the hot water injected into the tube pipe 132 by the control unit 110 and the temperature Ts of the wall surface is lower than the dew point temperature Tc And has a feature of preventing condensation from occurring by having a high temperature and volatilizing and removing the generated condensation with steam.

(2) The difference between the temperature of the wall surface and the temperature of the inside air of the building is within the condensation temperature difference (Td). The difference between the temperature of the wall surface (II) The following condition can be expressed by the following equation (5) as a concept opposite to the judgment condition for the difference.

This feature condensation temperature (T _d) is Equation (2) in it represents the temperature difference between the relative humidity and the building based on the air temperature (Ti) inside the dew point temperature (Tc), such a condensation temperature (T _d The temperature Ts of the wall surface is higher than the dew point temperature Tc when the temperature T _i of the inside of the building is larger than the temperature difference Ts of the wall surface temperature Lt; / RTI >

Accordingly, this feature indicates that condensation is not generated because the temperature Ts of the wall surface is higher than the dew point temperature Tc, and the dew condensation caused by the temperature higher than the dew point temperature Tc is removed by vaporization by steam.

(3) The characteristic of whether the internal humidity of the building exceeds the dew condensation removal threshold is a characteristic of using the humidity information inside the building detected through the first hygrometer of the dew condensation sensor unit 140, This is a feature to judge whether or not condensation has been removed by using the fact that the humidity inside the building is increased due to the steam evaporated in the process.

For example, the humidity of the interior of the building detected through the first hygrometer of the dew condensation sensor unit 140 at room temperature may be in the range of 90 to 95%. Such a dew condensation removing threshold can be changed according to the air temperature inside the building, and when the humidity inside the building rises to 96%, the condensation is removed.

According to the dew condensation removal step S240, the controller 110 turns off the operation of the boiler unit 120 or closes the valve 125 mounted on the tube 132 to stop hot water injection S250).

That is, if any one of the three characteristics of the condensation removal determining step (S240) is satisfied, the controller 110 can cut off the hot water injected into the tube pipe 132, thereby saving energy consumption.

According to another embodiment of the present invention having the above-described process, the controller 110 may repeatedly perform the steps from the step S210 for detecting the occurrence of dew condensation to the step S250 for stopping the hot water injection, It is possible to automatically determine whether or not condensation has occurred according to the condensation detection information received from the condensation detection sensor unit 140 in real time and to easily remove the condensation generated by circulating the hot water to thereby fundamentally solve the environmental problem caused by the condensation phenomenon .

Although the technical idea of the present invention has been specifically described according to the above preferred embodiments, it is to be noted that the above-described embodiments are intended to be illustrative and not restrictive.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention.
