Description

  The present invention relates to a ventilation system provided in a building so that air can move between different spaces such as between a living room and a passage.

  Various types of air conditioning systems to be introduced into buildings are conventionally known, and there are types of buildings suitable for each air conditioning system. For example, in the case of individual air conditioning in which an air conditioner such as an air conditioner is installed for each living room to be air-conditioned, each room is usually designed to be a space closed with respect to other living rooms and passages. Moreover, in the case of the whole building air conditioning which air-conditions several living rooms like patent document 1, each living room is normally designed so that it may become a space open with respect to another living room and a channel | path. Specifically, it is often designed to allow movement of air between other living rooms and passages through a return path that is an opening provided in the inner wall, an undercut of a door, or the like.

JP-A-5-172371

  However, the conventional building designed as described above cannot control the movement of air between adjacent spaces. For example, if each living room is a closed space with respect to other living rooms and passages, it may be necessary to exhaust air into the adjacent space or take in the air in the adjacent space. Is not provided, the movement of air cannot be controlled. For example, even if it is designed to allow air to move between adjacent spaces via return paths and undercuts, the air will move in a random manner and cannot be controlled by the resident side. . For this reason, for example, it was not possible to obtain a comfortable indoor environment by utilizing the adjacent space such as moving the warm air of the living room to the adjacent room.

  The present invention has been made to solve the above-described problems, and an object thereof is to obtain a ventilation system capable of controlling the movement of air between adjacent spaces.

  The ventilation system according to the present invention includes a plurality of ventilation holes provided on an inner wall facing the same space, each of the plurality of ventilation holes having an opening penetrating the inner wall, and at least one of the plurality of ventilation holes. The vent is characterized in that a fan is provided in the opening.

  According to this invention, since the fan is provided at the opening of at least one of the plurality of vents, the movement of air between the adjacent spaces can be controlled.

It is the schematic of the building which provided the ventilation system which concerns on Embodiment 1 of this invention. It is a perspective view which shows the vent hole of the ventilation system which concerns on Embodiment 1 of this invention. It is a perspective view which shows the vent of the ventilation system which concerns on Embodiment 1 of this invention, and shows the case where air moves to the direction different from FIG. It is a perspective view which shows the 1st modification of arrangement | positioning of the vent of the ventilation system which concerns on Embodiment 1 of this invention. It is a perspective view which shows the 2nd modification of arrangement | positioning of the vent of the ventilation system which concerns on Embodiment 1 of this invention.

Embodiment 1 FIG.
1 is a schematic view of a building provided with a ventilation system according to Embodiment 1 of the present invention. The living rooms 1a and 1b are on the first floor, the living rooms 2a and 2b are on the second floor, the living rooms 1a and 1b face the passage 1c, and the living rooms 2a and 2b face the passage 2c. The passage 1c on the first floor and the passage 2c on the second floor are connected in a staircase 3 like an atrium. In this building, the whole building air conditioning system is introduced to perform indoor heating and cooling.

In the entire building air conditioning system, cold air or warm air conditioned air is generated by the cooperation of the outdoor unit 4 and the indoor unit 5 connected to the outdoor unit 4 via a refrigerant circulation line (not shown).
The outdoor unit 4 exchanges heat between the outside air and the refrigerant, and includes a compressor, a water-cooled heat exchanger (or an air-cooled heat exchanger and a fan), and the like.
The indoor unit 5 is installed behind the ceiling, for example, and includes a heat exchanger, a fan, and the like. The indoor unit 5 exchanges heat between the refrigerant sent from the outdoor unit 4 via the refrigerant circulation line and the air sent from the ventilator 8 described later using a heat exchanger. And the conditioned air after heat exchange is sent out by a fan. The conditioned air sent out by the indoor unit 5 is blown out from the outlet 6 to each room through a supply duct (not shown).

The conditioned air blown out from the blow-out opening 6 is provided on the inner wall and functions as a return path. The passage 10c, 2c, The entire building is air-conditioned by going to the stairs 3 etc.
In the entire building air conditioning system, indoor return air is taken in through a suction port 7 provided on the ceiling side of the passage 2c. The return air taken in from the suction port 7 is exhausted outside the building by the ventilation device 8. The ventilator 8 also takes in outside air, and the taken-in outside air is sent to the indoor unit 5.

Here, FIG. 2 is a perspective view of the vent 10 provided on the inner wall that partitions the living room 2a and the passage 2c, which are indoor spaces, when the living room 2a is viewed from the passage 2c.
On the inner wall that partitions the living room 2a and the passage 2c, two vent holes 10a and 10b are provided. The vent hole 10a is provided above the vent hole 10b in the vertical direction, that is, on the ceiling side, and the vent hole 10b is provided vertically below the vent hole 10a, that is, on the floor side.

The vent 10a includes an opening 11a penetrating an inner wall that partitions the living room 2a and the passage 2c, a fan 12a provided so as to be fitted into the opening 11a, and the like. Similarly, the vent 10b includes an opening 11b penetrating an inner wall that partitions the living room 2a and the passage 2c, and a fan 12b provided so as to be fitted into the opening 11b.
The rotation of the fans 12a and 12b is controlled by a control unit (not shown) of the ventilation system. The control unit is configured such that a resident can instruct a desired rotation state such as rotation, stop, and rotation amount of the fans 12a and 12b via a remote controller (not shown).

Next, an operation example of the fans 12a and 12b of the vent holes 10a and 10b will be described.
As the fan 12a, for example, a fan that rotates so as to suck air from the living room 2a and exhaust it to the passage 2c is used. As the fan 12b, for example, a fan that rotates so as to suck air from the passage 2c and exhaust it to the living room 2a is used.

  When such fans 12a and 12b start to rotate under the control of a control unit (not shown), the air moves between the room 2a and the passage 2c in the flow shown by the arrow F1 in FIG. In other words, the air in the passage 2c enters the living room 2a from the vent 10b on the floor side of the living room 2a, and the air in the living room 2a passes through the vent 10a on the ceiling side of the living room 2a to the passage 2c.

When air moves between the living room 2a and the passage 2c in this way, when the living room 2a is cooled, the temperature spots in the vertical direction in the living room 2a such that cold air is likely to be distributed on the floor side are reduced. It is effective for. Moreover, since the warm air accumulated on the ceiling side passes through the passage 2c, the living room 2a becomes cool, and the indoor environment of the living room 2a becomes comfortable.
Further, even during heating, if the living room 2a is too warm, the warm air accumulated on the ceiling side can be released to the passage 2c, and the indoor environment of the living room 2a becomes comfortable. This is because, in the entire building air conditioning system, since the numerous air outlets 6 are provided in the living rooms 1a to 2b with respect to the passages 1c and 2c having no air outlet 6, the air conditioners 1a to 2b are likely to be excessively air-conditioned. is there.
Also, when the entire building air conditioning system does not perform heat exchange in the indoor unit 5 and only ventilates by blowing outside air from the outlet 6, the air between the room 2 a and the passage 2 c as indicated by the arrow F <b> 1. The indoor environment of the living room 2a can be adjusted using the passage 2c. For example, this is useful when the passage 2c is cool and the cool air is to be taken into the living room 2a.

  As shown in FIG. 2, the air in the passage 2c enters the room 2a from the floor side vent 10b of the living room 2a, and the air in the room 2a passes from the ceiling side vent 10a to the passage 2c. The movement may be caused by rotating only the fan 12a that draws air from the living room 2a and exhausts it into the passage 2c when it rotates. In this case, the fan 12b may not be rotated, or the air vent 10b may not be provided with the fan 12b. Similarly, when rotating, only the fan 12b that sucks air from the passage 2c and exhausts it to the living room 2a may be rotated. In this case, the fan 12a may not be rotated, or the air vent 10a may not include the fan 12a.

As the fan 12a, for example, a fan that rotates so as to suck air from the passage 2c and exhaust it to the living room 2a is used. Further, as the fan 12b, for example, a fan that rotates so as to suck air from the living room 2a and exhaust it to the passage 2c is used.
When such fans 12a and 12b start to rotate under the control of a control unit (not shown), the air moves between the room 2a and the passage 2c in the flow shown by the arrow F2 in FIG. That is, the air in the passage 2c enters the living room 2a from the vent 10a on the ceiling side of the living room 2a, and the air in the living room 2a passes through the vent 10b on the floor side of the living room 2a to the passage 2c.

When air moves between the living room 2a and the passage 2c in this way, when the living room 2a is heated, the temperature spots in the vertical direction in the living room 2a that warm air tends to be distributed on the ceiling side are reduced. It is effective for. Moreover, since the cold air accumulated on the floor side passes through the passage 2c, the living room 2a becomes warm, and the indoor environment of the living room 2a becomes comfortable.
Even when the room 2a is cooling, if the room 2a is too cold, the cold air accumulated on the floor side can be released to the passage 2c, and the room environment of the room 2a becomes comfortable.
Also, when the entire building air conditioning system does not perform heat exchange in the indoor unit 5 and only ventilates by blowing outside air from the outlet 6, the air between the living room 2 a and the passage 2 c as indicated by the arrow F <b> 2. The indoor environment of the living room 2a can be adjusted using the passage 2c. For example, this is useful when the passage 2c is warm and the warm air is to be taken into the living room 2a.

  As shown in FIG. 3, the air in the passage 2c enters the living room 2a from the vent 10a on the ceiling side of the living room 2a, and the air in the living room 2a passes from the vent 10b on the floor side of the living room 2a to the passage 2c. The movement may be caused by rotating only the fan 12a that draws air from the passage 2c and exhausts it to the living room 2a when it rotates. In this case, the fan 12b may not be rotated, or the air vent 10b may not be provided with the fan 12b. Similarly, when rotating, only the fan 12b that sucks air from the living room 2a and exhausts it to the passage 2c may be rotated. In this case, the fan 12a may not be rotated, or the air vent 10a may not include the fan 12a.

If both the movement of the air shown by the arrow F1 in FIG. 2 and the movement of the air shown by the arrow F2 in FIG. 3 can be made with the same fan without changing the fans used as the fans 12a and 12b, depending on the situation It is easy and preferable to switch the flow of the arrow F1 and the flow of the arrow F2. For this purpose, for example, as the fans 12a and 12b, a fan that sucks air from the passage 2c and exhausts it to the living room 2a is provided in the vent holes 10a and 10b, and only one of the fans 12a and 12b can be rotated according to the situation. That's fine. If only the fan 12a is rotated, the flow of the arrow F2 in FIG. 3 is generated, and if only the fan 12b is rotated, the flow of the arrow F1 in FIG. 2 is generated. Similarly, fans 12a and 12b are provided in the vents 10a and 10b as fans 12a and 12b for sucking air from the living room 2a and exhausting them to the passage 2c, and only one of the fans 12a and 12b can be rotated depending on the situation. That's fine.
Alternatively, a fan capable of forward and reverse rotation may be provided as at least one of the fans 12a and 12b, and the forward rotation and the reverse rotation may be switched depending on the situation. For example, if a fan capable of rotating in the forward and reverse directions is used as the fan 12a, the vent 10b may not include a fan.
Alternatively, a pair of vents 10a and 10b for generating the flow of the arrow F1 shown in FIG. 2 and a pair of vents 10a and 10b for generating the flow of the arrow F2 shown in FIG. May be.

Further, the vents 10a and 10b may be provided side by side in the horizontal direction as shown in FIG. This is useful when it is desired to adjust the indoor environment of the living room 2a while using the passage 2c by taking the warm air or cold air of the passage 2c into the living room 2a or letting the warm air or cold air of the living room 2a escape to the passage 2c. At this time, as long as one of the vents 10a and 10b has a fan, the other may not have a fan.
Further, the vent holes 10a and 10b may be provided obliquely so that the positions in the horizontal direction and the vertical direction are different as shown in FIG.

  Moving air between the living room 2a and the passage 2c through the vents 10a and 10b is also useful for ventilation of the living room 2a. The flow of air from the vent 10a to the vent 10b in the living room 2a or the flow of air from the vent 10b to the vent 10a in the living room 2a occurs, so that the air in the living room 2a is generated air. Since it is difficult to stay in the same place by being diffused by being caught in the flow of the room, the room is easily ventilated uniformly, and ventilation spots are reduced.

Thus, by providing a fan in at least one of the vents 10a and 10b, the flow of air between the vent 10a and the vent 10b is controlled. Thereby, it becomes possible to control the movement of air between the living room 2a and the passage 2c, and a comfortable indoor environment of the living room 2a can be obtained.
Further, the air flowing between the air vent 10a and the air vent 10b by the fans 12a and 12b is unlikely to be blown out from the air outlet 6, so that there is not much discomfort that the air current directly hits the body. Furthermore, since the fans 12a and 12b are accommodated in the openings 11a and 11b of the vents 10a and 10b, the design is not impaired.

  The rotation of the fans 12a and 12b may be designed so that a control unit (not shown) of the ventilation system automatically controls according to the situation in addition to manual control by a resident through a remote controller or the like. In the case of automatic control by the control unit, for example, temperature sensors are provided on the floor side and the ceiling side of both the living room 2a and the passage 2c, and the rotation of the fans 12a and 12b is controlled to an appropriate state based on the detected temperature difference. What is necessary is just to program a control part. Further, depending on whether heating is performed by the entire building air conditioning system, cooling is performed, or only ventilation by blowing outside air is performed, a flow from the vent 10a toward the vent 10b is generated in the living room 2a. To determine whether to control the rotation of the fans 12a and 12b or to control the rotation of the fans 12a and 12b so that a flow from the vent 10b to the vent 10a occurs in the living room 2a. The control unit may be programmed. It is possible to determine whether heating, cooling, or ventilation only is performed by obtaining operation information from the entire building air conditioning system.

  In the above description, the case where the ventilation system of the first embodiment is applied to a building that is air-conditioned by the entire building air conditioning system has been described. However, the ventilation system of the first embodiment may be applied to a building that is air-conditioned by individual air conditioning rather than whole-building air conditioning. For example, consider a case where a separate dedicated air conditioner is provided in a large space such as a living room. In this case, the vents 10a and 10b are provided on the inner wall that partitions the large space and the passage, and the vents 10a and 10b are also provided on the inner wall that partitions the passage and another living room such as a bedroom. And a passage takes in conditioned air from large space, and living rooms, such as a bedroom, use conditioned air through a passage. Specifically, in a living room such as a bedroom, the conditioned air in the passage is taken in from the floor-side vent 10b during cooling, and the conditioned air in the passage is taken in from the ceiling-side vent 10a during heating. In this way, even if there is no air conditioner in the living room such as a bedroom or an air conditioner with insufficient capacity is installed, the room environment can be made comfortable by heating and cooling using other spaces. . Also, unlike the entire building air conditioning system, buildings that are individually air-conditioned often do not have a ventilation system. By applying the ventilation system of the first embodiment, air can be moved between a room where people are present and the air is likely to get dirty, and a passage where air is not as dirty as the living room. There is a merit of introducing the ventilation system of Embodiment 1 into a building of individual air conditioning.

Moreover, the case where the two vent holes 10a and 10b were provided in the inner wall which partitions the living room 2a and the channel | path 2c was demonstrated above. However, the vent 10 may be additionally provided on the inner wall that partitions the living room 2a and the passage 2c. And you may abbreviate | omit a fan suitably from the vent hole 10 provided additionally.
Further, one of the vents 10a and 10b may be provided on the inner wall that partitions the space other than the passage 2c and the living room 2a. In short, the vents 10a and 10b may be provided on the inner wall facing the same indoor space 2a.
Moreover, you may provide both of vent hole 10a, 10b in the inner wall which partitions off the space other than the channel | path 2c, and the living room 2a. If the inner wall is an inner wall that separates the living room 2a from the adjacent living room, the movement of air between the living rooms can be controlled.

  Moreover, in the above, it demonstrated in detail using FIGS. 2-5 that the vent hole 10 provided in the inner wall which partitions the living room 2a and the channel | path 2c was vent hole 10a, 10b. Although the description is omitted to avoid duplication with this description, the vent holes 10 provided on the other inner walls shown in FIG. 1 are also similar vent holes 10a and 10b.

Moreover, in the above, the air outlet 6 of the whole building air conditioning system was provided in the living room 2a, and the living room 2a was air-conditioned. That is, the air outlet 6 is provided in the living room 2a as a temperature adjusting unit for adjusting the air temperature. However, various air conditioners such as a fan heater may be provided in the living room 2a to serve as the temperature adjustment unit.
Moreover, the temperature control part does not need to be provided in the living room 2a. In this case, the vents 10a and 10b function as air moving between spaces without the temperature control part. When moving air between spaces without a temperature control part, while being able to adjust the temperature of those spaces using a mutual temperature difference, it is useful for ventilation of those spaces.

  As described above, according to the first embodiment, the vent holes 10a and 10b are provided in the inner wall, and the fan is provided in at least one of the vent holes 10a and 10b. Thereby, the movement of air between the adjacent spaces partitioned by the inner wall can be controlled, and a comfortable indoor environment can be created by utilizing the adjacent spaces.

  In addition, one end of each of the openings 11a and 11b of the plurality of vents 10a and 10b is open to a space provided with a temperature control unit such as a blowout port 6 that controls the air temperature. If it does in this way, the indoor environment can be made comfortable for the air-conditioned space.

  In addition, the other ends of the openings 11a and 11b of the plurality of vents 10a and 10b are open to a space where there is no temperature adjusting unit such as the outlet 6 for adjusting the air temperature. If it does in this way, the temperature difference between adjacent rooms can be utilized and the indoor environment can be made comfortable efficiently.

  The plurality of vents 10a and 10b include vents whose positions in the vertical direction are different from those of the other vents. If it does in this way, indoor environment can be made comfortable by reduction of a temperature spot etc. in the perpendicular direction.

  The plurality of vents 10a and 10b include a pair of vents 10a and 10b provided with fans 12a and 12b in the openings 11a and 11b, respectively, and having different positions in the vertical direction. In this way, it is possible to efficiently reduce temperature spots in the vertical direction.

  In addition, when the space is cooled, air enters the space from the lower vent 10b in the vertical direction, and the air in the space from the upper vent 10a in the vertical position. The fans 12a and 12b are rotated so that the fan is removed. If it does in this way, it is effective for the temperature spot reduction etc. at the time of air conditioning.

  In addition, when the space is heated, air enters the space from the upper vent 10a whose position in the vertical direction is relatively higher, and the air in the space whose position in the vertical direction is relatively lower than the lower vent 10b. The fans 12a and 12b are rotated so that the fan is removed. If it does in this way, it is effective for temperature spot reduction etc. at the time of heating.

  In the present invention, any constituent element of the embodiment can be modified or any constituent element of the embodiment can be omitted within the scope of the invention.
