Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a condensation prevention structure for a wall panel that partitions a building into an interior and an exterior.

<Prior Art and Problems> Rooms or spaces (hereinafter referred to as outer natural room greenhouses) that are not sufficiently air-conditioned are created on the outer periphery of a building. This outer peripheral natural room greenhouse occurs mainly because the outer peripheral area is greatly influenced by natural conditions.

For example, during the winter season when the outside air has a low temperature and low humidity, the internal air is set to a high temperature and high humidity by the heating device. However, internal heat escapes to the outside through the wall panels that separate the inside and outside of the building (through-wall heat). This removes heat from the internal air and lowers its temperature. Moreover, since the amount of water contained in the air remains the same, the relative humidity increases. Therefore, there was a problem that dew condensation was likely to occur and the wall surface etc. would be contaminated.

Conventionally, the above-mentioned problem has been dealt with by improving the heat insulation performance of the wall panels, but this has not been an essential and effective solution.

<Means for solving the problem> Therefore, in the present invention, first, an external air intake port is provided on the outer surface of the wall panel, an external air supply port is provided on the inner surface, and the above-mentioned intake port is provided inside the wall panel. An air supply duct is provided to connect the inlet and the air supply port, and an air supply fan is disposed within the air supply duct to provide an air supply path for external air.

Further, an internal air inlet is provided on the inner surface of the wall panel, and an internal air outlet is provided on the inner surface at a location different from the inlet, and an internal air outlet is provided within the wall panel so that the inlet and the outlet are connected to each other. A circulation duct is provided to connect the air supply duct and the circulation duct, and a circulation fan is disposed within the circulation duct to provide a circulation path for internal air. They are placed adjacent to each other.

<Effect> The above technical means works as follows.

The air supply fan is driven to take in external air and pass it through the air supply duct, and at the same time, the circulation fan is driven to suck in internal air and pass it through the circulation duct. Then, since the supply air duct and the circulation duct are adjacent to each other via a partition made of a material with high heat exchange efficiency, heat exchange occurs between the low temperature outside air and the high temperature inside air. At this time, heat is removed from the humid internal air and condensation occurs. This condensation is collected and removed. The interior air thus dehumidified is blown out inside again. On the other hand, the low-humidity outside air is warmed by heat from the inside air and then supplied to the inside.

<Example> Hereinafter, the present invention will be explained based on the drawings.

FIG. 1 is a partially omitted vertical sectional view showing an embodiment of the present invention, FIG. 2 is a view taken along the line X--X in FIG. 1,
FIG. 3 is an external view of the inner surface of the wall panel, and FIG. 4 is an external view of the outer surface thereof.

In the figure, a wall panel 1 has the same dimensions as a normal wall panel (not shown), such as a width W, a height H, and a thickness T, and a heat insulating material 3 is attached to an outer surface 2.

First, the configuration of the wall panel 1 will be explained.

An intake port 4 for external air B ₁ (indicated by a dashed line in the figure) is provided at the bottom of the outer surface 2, and an air supply port 6 is provided at the top of the inner surface 5.

The intake port 4 and the air supply port 6 are connected by an air supply duct 7 disposed within the wall panel 1 to form an air supply path for external air _B1 .

The air supply port 6 is covered with a damper 8. An air supply fan 9 is disposed within the air supply duct 7 behind the damper 8.

On the other hand, a suction port 10 for internal air A ₁ (indicated by a two-dot chain line in the figure) is provided at the lower part of the inner surface 5.

Further, an air outlet 11 is provided at the upper part of the inner surface 5 at a position adjacent to the air supply port 6. Said suction port 1
0 and the air outlet 11 are connected by a circulation duct 12 disposed within the wall panel 1, forming a circulation path for internal air _a1 .

The air outlet 11 is covered with a damper 13, and a circulation fan 14 is disposed in a circulation duct 12b behind the damper 13.

As shown in FIG. 2, a plurality of air supply duct sections 7u with diagonal lines and a plurality of circulation duct sections 12u without diagonal lines are arranged in a staggered manner to form a substantially grid-like cross section.

The partition walls 15 between the air supply duct section 7u and the circulation duct section 12u are made of a material with good heat exchange efficiency, such as copper, and form one heat exchanger U.

Each circulation duct portion 12u of the heat exchanger U and the circulation duct 12a immediately after the suction port 10 are connected by a vinyl tube 16 or the like.

A saucer 17 is provided at the bottom of the circulation duct 12a.

The operation of the wall panel 1 having the above configuration will be explained.

The wall panel 1 forms an outer wall with the same configuration as a normal wall panel, and partitions the building into an interior A and an exterior B.

In winter, the internal air A ₁ is set to a higher temperature and higher humidity than the external air B ₁ by an air conditioning device (not shown). However, due to the heat flowing through the wall, the temperature of the internal air A ₁ at the outer periphery of the building decreases.
This increases the relative humidity in the internal air _A1 .

Then, the air supply fan 9 is driven to draw the external air _B1 into the wall panel 1. This external air _B1 is passed through the air supply duct section 7u of the heat exchanger U.

At the same time, the circulation fan 14 is driven to remove internal air A ₁
is sucked into wall panel 1. The lower part of the internal air _A1 has a lower temperature and higher humidity. This internal air A ₁ is sucked in from the suction port 10 provided at the bottom and passed through the circulation duct portion 12u of the heat exchanger U.

At this time, since the temperature of internal air A ₁ is higher than that of external air B ₁ , heat exchange is performed between internal air A ₁ and external air B ₁ in heat exchanger U.
Internal air A ₁ loses heat to external air B ₁ . As a result, moisture contained in the internal air _A1 condenses and adheres to the partition wall 15. This condensation is caused by vinyl tube 1.
6 and is dripped into the saucer 17. The interior air _A1 thus dehumidified is blown out into the interior A again.

On the other hand, external air _B1, which has a low temperature and low humidity, receives heat from internal air _A1 and is warmed.
is supplied with air.

<Effects of the Invention> As explained above, by using the wall panel of the present invention, it is possible to dehumidify the internal air by using the external air whose temperature is lower than that of the internal air.

By supplying external air, which has lower humidity than the internal air, into the interior, the humidity of the internal air can be reduced.

Therefore, it is possible to prevent dew condensation from forming on the outer periphery of the building, and also to prevent contamination of the wall surface.
