Description

TECHNICAL FIELD [0001] The present invention relates to a dew condensation prevention method,

The present invention relates to a method for preventing dew condensation in a dwelling house, wherein the air dew point temperature (measurement dew point temperature) of the dew condensation portion is increased by induction of autonomous participation of residents (residents) and intensive forced ventilation for a dew condensation portion The present invention relates to a dew condensation preventing method for a dwelling house, which can prevent dew condensation by keeping the dew point temperature lower than a set design dew point temperature.

Generally, a condensation phenomenon is a phenomenon in which air in the air condenses on the surface of an object while cooling the object in the air, thereby forming dew. The indoor surface condensation occurs when the surface temperature is lower than the air dew point temperature.

In particular, the interior of buildings such as apartment houses is generally higher in temperature and humidity than in the outside, and in winter, there is a large temperature difference between the inside and the outside of the house, so dew can easily occur on the wall surface or the window. There is a problem in that a problem occurs.

As a method for preventing or preventing the condensation phenomenon occurring in the interior of the building as described above, there is a method of making the surface temperature higher than the dew point temperature by attaching the heat insulating material and the dew condensation preventing material to the wall and the slab of the building, According to the design standard (2013.12, indoor temperature: 25 ℃, 50%, dew point temperature (in terms of the number of walls facing the outside), living conditions In the case of excessive humidity of 13.9 ° C or higher), condensation is inevitably generated as shown in FIG.

FIG. 6 is a graph showing an example of the occurrence rate of the condensation occurrence rate over time for one day when applying the design standard for prevention of condensation on the land surface through the measurement of the room temperature and humidity of the 68th generation of the central region, FIG. 7 is a time- The results show that the rate of occurrence of condensation increases from 14:00 to 22:00 and then drops again from 22:00. As a result, the lifestyle of residents (temperature, humidity, ), The measured dew point temperature was higher than the dew point temperature in the original design. As a result, it was found that condensation would occur even if the dew condensation prevention design (insulation material, condensation prevention material, etc.)

In addition, there is a method of discharging moisture to the outside through a ventilation system such as an electric heat exchanger (mechanical type, automatic type) installed on a balcony or the like, a ventilation unit, and a cooling and heating machine to lower the dew point temperature to a surface temperature or less. However, There is a problem that the effect of preventing condensation is insignificant.

Particularly, since the mechanical ventilation equipment is ventilated to the entire household, the energy waste becomes heavy, so that the electricity cost is increased to operate for 24 hours or for a long time. In addition, due to reasons such as cooling and heating loss and noise, 68% (mechanical type) have not operated the ventilator (study results).

In addition, the automatic ventilation system has a limitation in that the sensor does not reflect the temperature and humidity conditions of the actual condensation-weak areas because the sensor is located in the indoor center or the indoor controller for the purpose of ventilating the entire room. In other words, moisture is distributed widely from the generation source, and condensation occurs in the coldest part. However, since most of the sensors of the conventional automatic ventilation system are installed in the center of the room, there is an effect on ventilation, but it is difficult to expect a dew condensation prevention effect.

In the conventional automatic ventilation equipment, only the surface temperature or the relative humidity is measured and compared without considering the condensation-weak areas by the sensor. There is a problem in that the accuracy of the apparatus is deteriorated.

In addition, since the conventional condensation prevention method relies on the machine or the occupant (residents) must arbitrarily predict the occurrence of condensation and directly drive the ventilation system, there is a problem that the efficiency of preventing condensation from being lowered, It is impossible to improve the dew condensation phenomenon.

Open Patent Publication No. 10-2006-0021496 (Mar. 3, 2006) Patent Registration No. 10-1334299 (Nov. 22, 2013) Patent Registration No. 10-1334202 (Nov. 22, 2013)

The present invention can automatically predict the occurrence of condensation in real time, thereby facilitating self-help efforts by opening and closing the ventilation openings for the condensation prevention window (living room pvc window, front door), balcony wall ventilation openings and general window openings Can be performed. Further, since the present invention is adapted to use a ventilating device such as a toilet pan, it is possible to prevent the occurrence of condensation easily without adding additional facilities.

And a notification step in which if the calculated measured dew point temperature is equal to or higher than the predetermined design dew point temperature, a warning of risk of dew condensation on the dew condensation site is warned to the occupant.

In the sensor installation step, a temperature and humidity sensor is installed at one or more locations where condensation is most likely to occur, among a plurality of condensation fragile areas where condensation is expected to occur in a flat shape in the living space.

At this time, the above-mentioned condensation-weakened portion is a wall joint portion designated at the time of the earthquake-proof (Article 4) (a joint portion where the wall of the portion directly contacting with the outside air and the ceiling and bottom of the house meet at the same time), a mechanical equipment pipe duct ) And air duct (AD), indoor door area where excessive moisture is expected to be discharged, such as a built-in cabinet where the air flow is expected to be stagnated, a cabin door, The humidity sensor is installed at one or more of the condensation-weakening points. In addition to the temperature and humidity sensor, the condensation weak point is extended so that the exhaust port 31 of the exhaust pipe 30 is located close to the temperature and humidity sensor, and the exhaust port is installed in the ceiling or the like.
