Description

  The present invention relates to an indoor ventilation system.

  Various indoor ventilation systems have been provided in the past, but in the conventional indoor ventilation system, either or both of the air supply and exhaust ports are provided on the outer wall portion of the building that is visible from the outside, and the exterior of the building May make it worse. In particular, in apartment houses such as apartments, there are cases where air supply and exhaust ports are arranged in the outer wall portion. For this reason, an air supply port and an exhaust port may be provided on the roof eave, but this causes a problem that the total length of use of air ducts and air pipes becomes long.

  There is also a heat exchange ventilator that reduces the temperature change of indoor air due to ventilation by exchanging heat between the outside air supplied to the room and the air exhausted from the room, but it is easy to secure the installation space. It may not be.

  In view of the above problems, the present invention can reduce or eliminate the number of air supply / exhaust ports from the outer wall portion, can improve the appearance of the building, and allows air to pass therethrough. It is an object of the present invention to provide an indoor ventilation system that can reduce the total use length of the air pipe and the air pipe, and in addition, can perform heat exchange ventilation and easily secure an installation space for the heat exchange ventilation. .

The above problem is that the wall that partitions the interior of the building is a wall having a hollow portion, and the hollow portion of the wall communicates from the roof side to the outside.
The wall is provided with an air supply port for ventilation and an exhaust port for discharging air from the indoor side, and the air supply for ventilation which sends the outside air from the roof side toward the air supply port through the hollow portion of the wall One of the passage portion and the exhaust passage portion that sends air from the indoor side to the roof side from the exhaust port, and the other passage portion is partitioned by the one passage portion and the passage partition in the hollow portion. The passage partition is formed of a heat exchange partition, and heat is exchanged between the outside air passing through the ventilation supply passage section and the air from the indoor side passing through the exhaust passage section via the heat exchange partition. It is solved by an indoor ventilation system characterized by

  In this indoor ventilation system, a ventilation inlet is provided in a wall that divides the interior of the building, and the wall is a wall having a hollow portion, and the hollow portion of the wall communicates from the roof side to the outside. Since the air passage portion is provided in the hollow portion of the wall, the air supply port for ventilation can be omitted from the outer wall of the building, and the number of air supply and exhaust ports can be reduced or eliminated from the outer wall portion. Appearance can be improved.

  Moreover, any one of the ventilation air supply passage section that sends the outside air from the roof side toward the air supply opening and the exhaust passage section that sends air from the indoor side to the roof side from the exhaust opening through the hollow portion of the wall. Therefore, the duct and the air pipe for the one passage portion can be eliminated, and the total use length of the duct and the air pipe through which air passes can be shortened.

  In addition, both passage portions are partitioned by a passage partition and are provided in a hollow portion of the wall. The passage partition includes a heat exchange partition, and the outside air and exhaust passage that passes through the ventilation air supply passage portion through the heat exchange partition. Heat exchange is possible with indoor air passing through the section, so heat exchange ventilation is possible, and securing of installation space for heat exchange ventilation can be facilitated by using the wall. it can.

  In addition, an underfloor air passage portion that connects the hollow portion of the wall and the lowermost underfloor space portion is provided so that air under the floor is discharged from the roof side through the exhaust passage portion of the wall. It's also good.

  In this case, it is possible not only to promote underfloor ventilation, but also to use the heat for heat exchange ventilation when the underfloor becomes warm due to geothermal heat in winter and in summer. The cool air under the floor can be used for heat exchange ventilation.

  Since the present invention is as described above, the number of air supply / exhaust ports can be reduced or eliminated from the outer wall portion, the appearance of the building can be improved, and a duct through which air is passed. In addition, the total use length of the air pipe can be shortened, and in addition, heat exchange ventilation is possible, and it is easy to secure an installation space for the heat exchange ventilation.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings.

  The indoor ventilation system of the embodiment shown in FIGS. 1 to 3 is applied to a two-story building 1 for an apartment house such as an apartment as shown in FIG. 3, and the building 1 is shown in FIGS. As shown in FIG. 2, the adjacent doors 3 and 5 on the lower floor and the adjacent doors 2 and 4 on the upper floor are each partitioned by a boundary wall 6, and the boundary wall 6 is made of a wall having a hollow portion 7. The hollow portion 7 communicates with the outside from the roof 8 side. The boundary wall 6 may be a series of upper and lower floor walls, and the boundary walls are provided so that the hollow portions communicate with each other. Also good.

  In each of the doors 2 to 5, as shown in FIG. 1, the boundary wall 6 is provided with a ventilation exhaust port 10 as well as a ventilation air supply port 9. The air pipe 11 is installed as a passage partition, the air pipe 11 is connected to the ventilation air supply port 9, and the air is sent through the air tube 11 from the roof 8 side toward the air supply port 9. The air supply passage section 12 is provided. The ventilation exhaust port 10 communicates with the hollow portion 7 of the boundary wall 6, and the space in the hollow portion 7 serves as an exhaust passage portion 13 that sends room air from the exhaust port 10 to the roof 8 side. The air pipe 11 is constituted by a heat exchange pipe, and the outside air passing through the ventilation supply passage section 12 and the air from the indoor side passing through the exhaust passage section 13 exchange heat through the air pipe 11. It is made like that.

  Further, in the present embodiment, an exhaust pipe 15 from a combustion device 14 for heating or hot water supply installed indoors or outdoors communicates with the exhaust passage portion 13 of the hollow portion 7 of the wall 6 and is provided on the first floor of the building. The underfloor space portion 16 communicates with the exhaust passage portion 13 through the underfloor air passage portion 17 and is discharged outside from the roof 8 side through the exhaust passage portion 13.

  In the above indoor ventilation system, the ventilation air supply port 9 is provided in the field wall 6, and the field wall 6 is made of a wall having a hollow part 7, and the hollow part 7 communicates with the outside from the roof 8 side. Since the ventilation air supply passage portion 12 is provided in the hollow portion 7 of the boundary wall 6, the ventilation air supply port 9 is omitted from the outer wall of the building 1, and the ventilation exhaust port 10 is also connected to the boundary wall 6. Since the ventilation exhaust passage 13 is also provided in the hollow portion 7 of the wall 6 in the same manner, the number of ventilation air supply / exhaust ports can be reduced or eliminated from the outer wall portion of the building 1. As a result, the appearance of the apartment house building 1 can be made to have a clean appearance.

  Moreover, since the hollow portion 7 of the boundary wall 6 is the exhaust passage portion 13 that sends the air in the room 18 from the exhaust port 10 to the roof 8 side, the air pipe for the exhaust passage portion 13 can be eliminated, The total use length of the air pipe can be shortened.

  In addition, while both the passage parts 12 and 13 are partitioned via the tube wall of the heat exchange air pipe 11, the outside air passing through the ventilation air supply passage part 12 while ventilating by driving the fan, Since heat is exchanged with the indoor air passing through the exhaust passage 13, heat exchange ventilation is possible, and securing the installation space for the heat exchange ventilation can be facilitated by using the wall 6. .

  Further, in the above embodiment, the exhaust pipe 15 from the combustion device 14 communicates with the exhaust passage portion 13 of the hollow portion 7 of the boundary wall 6, so that, for example, in the winter, when the outside air temperature is low, In the hollow portion 7 of the boundary wall 6, the outside air passing through the ventilation air supply passage portion 12 and the warm exhaust gas from the combustion device 14 perform heat exchange, and a decrease in the indoor temperature due to ventilation can be suppressed to a small level. Needless to say, a configuration is adopted in which heat exchange is not performed in summer or in the intermediate period.

  In addition, the underfloor space portion 16 on the first floor of the building is communicated with the exhaust passage portion 13 through the underfloor air passage portion 17 so that the air under the floor is discharged from the roof 8 side through the exhaust passage portion 13. When the ground floor becomes warm due to underground heat in winter, or when the solar heat is stored in the soil concrete under the floor by a solar heat collector or the like, the hollow of the wall 6 is hollow. In the section 7, the outside air passing through the ventilation air supply passage section 12 and warm underfloor air perform heat exchange, and a decrease in the room temperature due to ventilation can be kept small. Also, in summer, cool air under the floor can be used for heat exchange ventilation, so that the rise in room temperature due to ventilation can be kept small.

  Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, in the above embodiment, the case where both the ventilation inlet port 9 and the ventilation exhaust port 10 are provided in the field wall 6 is shown. However, the ventilation exhaust port 10 is provided in the outer wall of the building and is used for ventilation. The air supply port 9 and the exhaust pipe of the combustion device 14 may be passed through the hollow portion 7 of the field wall 6 to exchange heat between the external air for supply and the exhaust gas. That is, “air from the indoor side” is a concept including not only indoor air but also various air exhausted through the hollow portion 7 of the boundary wall 6. It is a concept that includes gas, and therefore the combustion device 14 itself may be provided indoors or outdoors as described above.

  Further, in the above embodiment, the case where the air pipe 11 installed in the hollow portion 7 of the boundary wall 6 is the air supply passage portion 12 and the hollow portion 7 is the exhaust passage portion 13 is shown. The inside of the pipe 11 may be an exhaust passage portion 13, and the inside of the hollow portion 7 may be an air supply passage portion 12. Not only the air pipe 11, but also the exhaust passage portion 13 and the air supply passage portion 12 are partitioned so that heat exchange is possible. A heat exchange partition may be employed.

  Moreover, although the case where it applied to the boundary wall of the building for collective housing was shown in said embodiment, it is not restricted to this, The wall which partitions the inside of a building in various buildings, such as a detached house building and an office building It is also possible to apply to. Moreover, there is no restriction | limiting in the number of floors of a building, 1 floor may be sufficient and 3 floors or more may be sufficient. Furthermore, the term “roof side” may be a very roof as illustrated, or an eaves provided on the roof side.
