Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an outer wall structure in a building where a wall-through air conditioner is installed.

Prior Art As shown in FIG. 7, the outer wall structure (wall panel body 2) at the location where the wall-through type air conditioner 1 is installed is provided with a communication path 3 for supplying and exhausting air to the air conditioner 1 (Actual Publication 1-
(See Publication No. 25224).

The indoor side port 4 of the communication path 3 is connected to the supply/exhaust port 5.6 of the air conditioner 1 installed on the floor of the room, and the outdoor lower side opens to the outdoors on the outer surface of the wall panel body 2.

In case 2, the supply/exhaust port 5 of the wall-through air conditioner 1
, 6 are usually provided in the upper part, so the supply/exhaust communication passage 3 is also provided in the upper part of the wall panel body 2, and the outdoor lower part thereof corresponds to the upper part of the air conditioner 1. It is open in position.

However, if the outdoor lower is located at a position corresponding to the upper part as described above, the communication path 3 connecting to the air conditioner's supply/exhaust ports 5 and 6 will be close to horizontal and short as shown in the figure, so the communication path 3 will be Raindrops can easily get into the inner opening. Therefore, raindrops may enter the air conditioner 1, or rainwater may leak into the room from the joint between the wall panel body 2 and the air conditioner 1.

Problems to be Solved by the Invention An object of the present invention is to provide an outer wall structure of a building, which prevents rainwater from entering the room through the supply/exhaust passage for a wall-through air conditioner. shall be.

Measures to solve the problem: Provide a supply/exhaust passage for the wall-through air conditioner on the outer wall of the building.

The outdoor side port is opened at a position below the bottom surface of the air conditioner.

Operation The supply and exhaust of the wall-through type air conditioner is carried out through a communication passage for supply and exhaust that has an outdoor side port and an indoor side port.

The configuration in which the outdoor side port is located below the bottom surface of the air conditioner prevents rainwater from moving toward the indoor side port of the supply/exhaust communication passage. It also allows for the natural flow of condensed water and drain inside the air conditioner.

Embodiment FIG. 1 shows the outdoor side (left) and the indoor side (left) with the outer wall 8 of the building as the boundary.
right) is shown.

The outer wall 8 is constructed using a curtain wall method, and the wall panel bodies 2 (2a, 2b, . . . ) are attached to the building frame 9 by fixing fittings 10. It is installed with... Wall panel body 2a
is a panel body that constitutes the opening 11 in the building outer wall 8, and the wall panel body 2b is a panel body that constitutes the opening 11 in the building outer wall 8, and the wall panel body 2b is the spandrel part 1 between them.
2.

The wall panel body 2b is placed at the slab (floor) 13 position,
The upper half serves as a waist wall 14 on the upper floor, and the lower half serves as an attic shielding wall 15 on the lower floor.

A wall-through type air conditioner 1 (hereinafter referred to as the air conditioner) is arranged on the indoor side of the waist wall 14, and its supply/exhaust ports 5, 6 (
Fig. 2) is the supply/exhaust passage 3 (hereinafter referred to as
(referred to as a communication path). This air conditioner 1 is of an air source heat pump type.

The communication path 3 is provided inside the wall panel body 2b, the indoor side port 4 is located at the upper part of the indoor side surface in line with the air supply/exhaust ports 5 and 6 of the air conditioner 1, and the outdoor side lower side is located at the upper surface of the floor 13. It opens outdoors at the vertical center of the spandrel section 12 at a lower position.

That is, the wall panel body 2b itself has a structure in which an external panel 17 is attached to the outer surface side of a frame structure 16 assembled into a rectangular shape, and a space 18 is formed on the indoor side when the wall panel body 2b is attached to the frame structure 9. A communication path 3 is formed in this space 18. The outdoor lower portion of the communication path 3 is located below the bottom surface of the air conditioner 1.

In FIG. 1, reference numeral 19 in the communication path 3 is a bird net that prevents birds from building nests inside the communication path 3.

The communication passages 3 are formed individually corresponding to the air supply and exhaust ports of the air conditioner 1, and are each provided with an indoor side port 4 and an outdoor lower side (FIG. 2).

When the air conditioner 1 is driven, outside air introduced from the outdoor lower side passes through the communication path 3 as shown by the white arrow, reaches the indoor side port 4, and is taken into the air conditioner 1 from the air supply port 5. The outside air that has undergone heat exchange inside the air conditioner 1 then enters another communication path 3 from the exhaust port 6, reaches the outdoor side port in the opposite direction to the above, and is discharged to the outside air. On the other hand, as is well known, a circulation path for indoor air is formed inside the air conditioner, and after the introduced indoor air exchanges heat with the outside air inside the air conditioner, it is recirculated as shown by arrow A. returned to the room.

In this way, if the heat exchange is from outside air to indoor air, heating of the room is performed, and if the opposite is the case, cooling is performed.

At this time, if it is a rainy day, raindrops and rainwater will enter the communication passage 3 from the outdoor lower part, but since this intake lower part is located below the bottom of the air conditioner 1, be sure to avoid the part that bends upward. Therefore, rainwater does not reach the indoor side entrance 4 of the communication path 3.

In addition, if the air conditioner is an air source heat pump type,
Regardless of the operating mode (heating), the heat exchanger on the expansion side of the heating medium becomes low temperature and condenses in this area, generating condensate, but if necessary, by connecting the condensate piping to the communication path 3, this condensate can be transferred to the air conditioner. It can be easily discharged from the outdoor lower part located lower than the bottom.

Note that the wall panel body 2 combined with the wall-through type air conditioner 1 often constitutes a spandrel portion of a building because the air conditioner 1 is placed on the floor as described above. The appearance of the exterior surface has a great influence on the exterior appearance of the building, and if the outdoor lower is casually opened at this location due to the convenience of the air conditioner 1 side, it will not harmonize well with the wall design of the building and the building will be damaged. It may damage the appearance of the product.

However, according to this embodiment, the outdoor lower part located at the vertical center of the spandrel part 12 can be easily obscured by horizontal strips or grooves formed in this part as part of the wall design, and the wall-through type Since the outdoor side entrance of the air supply/exhaust communication path for the air conditioner can be incorporated into the wall design relatively easily, the external appearance of the building is less disturbed by the outdoor side entrance.

That is, the vertical center portion of the bandrel portion 12 is
This is a place where various improvements can be made relatively easily while balancing the design of the outer wall 8 with the vertical and horizontal lines that appear in the upper and lower openings 11.

FIG. 3 shows a second embodiment, in which the supply/exhaust ports 5 and 6 of the air conditioner 1 are provided at a lower position compared to the first embodiment, and correspondingly, the communication path 3 is installed on the indoor side. The mouth 4 is also formed at a low position.

Other configurations, such as the position of the outdoor lower, are the same as in the first embodiment. Therefore, even in this case, since the outdoor lower side of the communication path 3 is located below the bottom of the air conditioner 1,
The same effects as in the first embodiment can be achieved.

FIG. 4 shows a third embodiment, in which the air conditioner 1 is provided with supply/exhaust ports 5, 6 on the bottom surface in contrast to the first embodiment, and also fits into the expected dimension m of the wall panel body 2b. The above-mentioned supply/exhaust ports 5 and 6 are arranged so as to protrude toward the outdoors.

Other configurations such as the position of the outdoor lower portion of the wall panel body 2b are the same as in the first embodiment. Therefore, the communication path 3 provided in the wall panel body 2 is shortened, but even in this case, there is inevitably a vertical portion to connect to the supply/exhaust port 5°6 on the bottom of the air conditioner, which prevents rainwater from entering. is prevented,
In the end, the same effects as in the first embodiment are achieved.

Furthermore, in this embodiment, since only the air conditioner 1 protrudes toward the indoor side, the indoor comfort is improved.

FIG. 5 shows a fourth embodiment, in which, in contrast to the first embodiment, the air conditioner 1 is completely fitted within the dimension m in the expected direction of the wall panel body 2b, and has supply and exhaust ports 5 and 6 on the bottom surface. There is.

The structure of the wall panel body 2b is different from that of the first to third embodiments described above, in that a reinforcing frame 20 is further attached to the indoor side of these frame structures 16, thereby securing strength and building space within the space. Air conditioner 1 is installed.

A communication path 3 formed in the wall panel body 2b, its outdoor lower side,
The arrangement of the indoor side entrance 4 is the same as in the third embodiment,
The outdoor lower side opens at a vertically central portion of the bandrel portion 12 at a position below the bottom surface of the air conditioner 1.

This embodiment also exhibits the same effects as the other embodiments. In addition, with this structure, the wall panel body 2b and the air conditioner 1 are integrated, and the air conditioner 1 becomes a part of the wall panel body 2b. Improves sex.

FIG. 6 shows a fifth embodiment, in which a grid 21 is arranged on the lower outdoor side of the communication path 3 in place of the bird net 19 in the third embodiment. This grid 21 includes a plurality of horizontal blades 22 arranged at equal intervals.

With this configuration, raindrops attempting to enter the communication path 3 first collide with the horizontal blades 22 at the outdoor lower part of the entrance and are prevented from directly entering, so that they are prevented from reaching the air conditioner 1. It is blocked more efficiently. Of course, it also has a bird-repelling effect.

Furthermore, this configuration has the function of rectifying the introduced outside air into a laminar flow by a plurality of blades 22 when it is on the communication path 3 or the air supply side, which reduces the resistance when the outside air passes through the communication path 3. This reduces the air supply load on the air conditioner 1.

This grid 21 exhibits the same effect even when attached to the outdoor lower part of other embodiments.

The above is an example. The outer wall structure of the present invention can also be applied to wall-through type air conditioners other than air source heat pump type.

Effects of the Invention It is possible to efficiently prevent rainwater from entering the air conditioner from the supply/exhaust communication path provided on the outer wall.

If necessary, you can easily drain water from the air conditioner such as a drain.
