Description

The present invention relates to a ventilation system.

For example, in Patent Document 1, a sound absorbing material glass wool is used on the lower surface of the floor plywood, which is the floor material on the upper floor, excluding the floor joists, leaving a gap between the ceiling and the plaster board, which is the ceiling material on the lower floor. A wooden house with soundproofing is disclosed.

In the case of a wooden house as in Patent Document 1, it is difficult to maintain airtightness in the soundproofed room on the second floor, so it is not possible to completely eliminate sound leakage from the room on the second floor to the room on the lower floor. In addition, the users of the rooms on the second floor are usually limited to their families. Therefore, there was almost no risk that an unspecified number of people would enter the room on the second floor for a long time and cause oxygen deficiency or carbon dioxide poisoning.

However, recently, soundproof rooms that can be easily used by an unspecified number of people have become available as rental music studios. For example, when a vacant room is remodeled to create a soundproof room and a large number of users are packed in it, the air conditioner is fully activated to adjust the temperature and humidity. If a piano concert is held here, adults and children will be locked up in the soundproof room for a long time, but since the air conditioner has almost no ventilation function, there is concern that it will cause oxygen deficiency and carbon dioxide poisoning. .. On the other hand, adults and children differ greatly in oxygen consumption, carbon dioxide emissions, and height. Therefore, in order for anyone to use the soundproof room with peace of mind, it is essential to construct a ventilation system that takes into consideration the differences between adults and children.

The present invention has been made in view of such circumstances, and an object thereof is to provide a ventilation system capable of use with confidence anyone.

(Embodiment 1)
FIG. 1 is a perspective view showing the appearance of the soundproof chamber 1 according to the first embodiment of the present invention, and FIG. 2 is a vertical sectional view showing a detailed structure of the soundproof chamber 1 according to the first embodiment. However, the left side of the paper in FIG. 1 corresponds to the north side of the soundproof room 1, and the right side corresponds to the west side of the soundproof room 1. The present inventor has actually created a soundproof room 1 on the premises of his / her home by utilizing his experience of engaging in soundproofing measures for many years as an engineer of a plant maker, and the results obtained there are described below.

As shown in FIGS. 1 and 2, the soundproof room 1 is a wooden house built independently on the ground, and is basically a solid concrete foundation with main parts such as wooden pillars and beams. A structural part is made, but a heavy sound source 9 can be accommodated inside the structural part. Examples of the sound source 9 include a grand piano and a large automatic musical instrument that weigh more than 500 kg. The reason why the building was not entirely made of concrete is that when a grand piano or the like is stored there, continuous dehumidification with an air conditioner may be required to prevent the generation of mold. On the other hand, in the case of a wooden house built independently on the ground, there are few such problems, and in the case of a solid concrete foundation limited to the underfloor, moisture enters the room from the ground in the summer. On the other hand, it is thought that it plays a role of appropriately humidifying the room in winter.

Therefore, in this soundproof room 1, a solid concrete foundation 2 placed on the crushed stone 21 and a glass wool (corresponding to the first soundproofing material) 31 erected on the solid foundation 2 are made into two layers. The double wall 3 contained in the panel board and the anti-vibration hanger 42 are hung from the roof 10, and the glass wool (corresponding to the second soundproofing material) 41 is also contained in the panel board in two layers. A heavy ceiling 4 is provided, and the double wall 3 and the double ceiling 4 are connected almost seamlessly, and two layers of rock wool (corresponding to a third soundproofing material) 22 are placed on the solid foundation 2. The concrete flooring material 5 is placed in a state of being sandwiched between the two.

Each layer of glass wool has a thickness of about 100 mm, and each layer of rock wool has a thickness of about 25 mm. Further, a significant gap is eliminated between the solid foundation 2 and the double wall 3 and between the double wall 3 and the double ceiling 4 by packing or a sealer.

The solid foundation 2 is strong against pitching during an earthquake, but does not prevent rolling. Therefore, the periphery of the solid foundation 2 is raised, and the periphery of the flooring material 5 is brought into contact with the rock wool 22 in a state of being extended and sandwiched in the rising portion. This makes it possible to handle not only pitching during an earthquake but also rolling.

In addition, the symmetry on the indoor plane is reduced, and the aspect ratio thereof is significantly changed, so that the sound waves emitted from the sound source 9 are less likely to interfere with each other even if they are reflected by the wall. In addition to this, for example, a felt sound insulation sheet (sound insulation material) 32 is attached to the panel board on the north side of the double wall 3, and a sound absorption panel is used for the panel board on the lower inner surface of the double ceiling 4. This reduces the wall reflection itself.

Of the circumference of the double wall 3, from the lower part on the north side and the west side to the middle part, a slight step portion is provided in the thickness direction thereof to provide an opening notched outward, and glass wool or the like is included therein. Double doors 6a and 6b are provided so that they can be opened and closed.

A packing is interposed between the double doors 6a and 6b and the corresponding opening to prevent sound waves from slipping through. The double door 6a is a relatively large door provided for carrying in and out of the sound source 9, and a small space is provided between the inner door and the outer door arranged so as to face each other. It is closed during the performance. The double door 6b is a relatively small door provided for people to enter and exit, and a space is provided between the inner door and the outer door provided at right angles to each other so that a person can stay. By adopting the so-called airlock type, it can be opened and closed even during a performance.

Of the periphery of the double wall 3, a slight step portion is provided in the thickness direction of the middle portion on the lateral side of the double door 6b to provide an opening notched outward, and a triple layer is provided therein. The glass window 7 is detachably attached. As a result, so-called light can be taken. Although not shown, a similar glass window is provided on the east side.

Of the periphery of the double wall 3, an air supply duct 82 and an exhaust duct 84 penetrating the upper part of the double door 6b are provided, and a ventilation device 14 is provided on the double ceiling 4 to form an air supply duct 82. The exhaust duct 84 is connected to the ventilation device 14 in a bent state at least twice (see FIG. 3). Both the air supply duct 82 and the exhaust duct 84 are provided with a heat insulating material for dew prevention. As a result, sound leakage from the air supply duct 82 and the exhaust duct 84 is reduced, the room can be ventilated, and the humidity rise in the room is suppressed.

Here, as a specific method for bending the air supply duct 82 and the exhaust duct 84, it is preferable to bend the air supply duct 82 and the exhaust duct 84 twice or more by 45 degrees in the same direction. As a result, the increase in pipeline resistance due to the air passing through the air supply duct 82 and the exhaust duct 84 is minimized to ensure ventilation performance, while sound waves are emitted inside the air supply duct 82 and the exhaust duct 84. Sound leakage due to slipping through can be reduced.

Make small holes in the wooden part 33 at the bottom of the double wall 3 at intervals of about 0.3 to 1 m, inject a chemical solution of an insect repellent into the small holes, and then backfill each small hole with a putty or the like. Therefore, so-called termite countermeasures are taken. However, no measures against termites have been taken for the wooden part 34 above the double wall 3 and the pillars between the two wooden parts 33 and 34 (not shown), but all the wooden parts used in the construction stage are insect repellent in advance. It is preferable to treat it.

FIG. 3 is a schematic view showing a ventilation system 8 of the soundproof room 1 according to the first embodiment. The solid line in FIG. 3 indicates the duct, and the broken line indicates the electric system. As shown in FIG. 3, in the ventilation system 8, the soundproof room 1 is provided by the air supply fan 14a from the air filter 81 through the air supply duct 82 according to the number of adults M1 and children M2 housed in the soundproof room 1. The amount of air supplied to the inside of the soundproof chamber 1 and the amount of air discharged from the inside of the soundproof chamber 1 through the exhaust duct 84 to the exhaust port 83 by the exhaust fan 14b can be adjusted to ventilate the inside of the soundproof chamber 1. The air fan 14a and the exhaust fan 14b are integrated to form the ventilation device 14. The air filter 81 removes particles such as cedar pollen, which is a causative substance of pollinosis, and PM2.5, which is a causative substance of air pollution. The most basic grade ventilation system 8 will be described below.

Here, a “strong” or “weak” selection switch 602 is provided separately from the power switch 601 of the ventilation device 14. The power switch 601 and the selection switch 602 are electrically connected to the air supply fan 14a and the exhaust fan 14b through the control panel 600. Then, the user or the owner of the soundproof room 1 (not shown) sees the selection table as shown in Table 1 and switches the selection switch 602 to either “strong” or “weak”. The children in Table 1 are assumed to be kindergarten children or children in the lower grades of elementary school. At first, since the user is not in the soundproof room 1, the power switch 601 is "off" and the selection switch 602 is "weak".

When the users of the soundproof room 1 are one teacher (adult) and three children (children), the teacher presses the power switch 601 of the ventilation device 14 to turn it "on", and see the selection table in Table 1. , The selection switch 602 is left "weak". Then, the air supply fan 14a and the exhaust fan 14b rotate at a low speed, and the outside air is supplied into the soundproof chamber 1 through the air filter 81 and the air supply duct 82, and the air in the soundproof chamber 1 becomes the exhaust duct 84. It is exhausted to the outside of the soundproof chamber 1 through the exhaust port 83. At this time, the amount of air supply and the amount of exhaust air are set to be relatively small (the setting value 1 is the maximum value of the ventilation "weak" range in Table 1), but the diagonal line downwards to the right in Table 1. In the case of one adult shown in the area of, it can be seen that up to six children shown in the shaded area rising to the right are OK.

A mother (adult) with two children (children) enters the soundproof room 1 through the outer door 6b2 and the inner door 6b1 of the double door 6b. Then, since the soundproof room 1 has 2 adults and 5 children, the teacher switches the selection switch 602 to "strong". Then, the air supply fan 14a and the exhaust fan 14b rotate at high speed, and the outside air is supplied into the soundproof chamber 1 through the air filter 81 and the air supply duct 82, and the air in the soundproof chamber 1 becomes the exhaust duct 84. It is exhausted to the outside of the soundproof chamber 1 through the exhaust port 83. At this time, the amount of air supply and the amount of exhaust air are set to be relatively large (the setting value 2 is the maximum value of the "strong" range in Table 1), but the diagonal line at the lower right in Table 1 In the case of 2 adults shown in the area, it can be seen that up to 10 children shown in the double shaded area rising to the right are OK.

When the lesson of the first child (3 people) is over, the teacher goes out from the soundproof room 1 through the inner door 6b1 and the outer door 6b2, so there are 2 adults and 2 children in the soundproof room 1, so the teacher is a selection switch. Switch 602 to "weak". Then, the air supply fan 14a and the exhaust fan 14b return to low-speed rotation, the outside air is supplied into the soundproof chamber 1 through the air filter 81 and the air supply duct 82, and the air in the soundproof chamber 1 becomes the exhaust duct 84. It is exhausted to the outside of the soundproof chamber 1 through the exhaust port 83. The air supply amount and the exhaust amount at this time return to the set value 1. Then, when the number of users exceeds the maximum number, the required amount of air exceeds the set value 2, so that the teacher limits the number of people who can enter the soundproof room 1. The same applies hereinafter.

At this time, the teacher (adult) switches the selection switch 602 for each lesson break, but if it is considered troublesome, it may be left as "strong". However, the same point is that when the number of users exceeds the maximum number, the number of people who can enter the soundproof room 1 is limited. When everyone leaves, the teacher turns off the power switch 601 and sets the selection switch to "weak". Then, both the air supply fan 14a and the exhaust fan 14b stop rotating. Only by such a manual operation, oxygen deficiency and carbon dioxide poisoning due to insufficient ventilation in the soundproof chamber 1 can be easily and surely avoided.

After the soundproof room 1 was completed, the sound source 9 was placed in the center of the room. The sound source 9 is a combination of piano and drum sounds, etc., and extends from a high range to a low range. After that, I actually measured the A characteristic using a sound level meter while turning on and off the sound source 9. As a result, even when the noise level of the sound source 9 was 110 db at the maximum, the outdoor noise level was about 30 to 40 db, and the sound reduction effect was actually about 70 to 80 db.

Here, when the sound source 9 is turned on, the maximum measured value at a position 1 m away from the sound source 9 is 110 db, and the measured value at a position 1 m away from the outer wall surface of the double wall 3 at this time is It was about 30 db, and the measured value just outside the triple glass window 7 was about 40 db. When the sound source 9 is turned off, the measured value at a position 1 m away from the sound source 9 is about 30 db, the measured value at a position 1 m away from the outer wall surface of the double wall 3 is about 30 db, and the triple glass window 7 The measured value immediately outside was about 30 db. 30db is the same noise level as the outdoor environmental sound (rain sound, etc.).

Therefore, it was found that the sound leakage was almost completely eliminated in the soundproof room 1. Since a commercially available soundproof room has only a sound reduction effect of about 20 to 40 db, it can be said that this is an epoch-making result compared to the fact that there is some sound leakage even if the soundproof room is provided.

As described above, according to the soundproof room 1 of the first embodiment, the solid foundation 2 is erected on the solid foundation 2, the double wall 3 containing the glass wool 31 is suspended from the roof 10. A state in which the double ceiling 4 including the glass wool 41 is provided, the double wall 3 and the double ceiling 4 are connected to each other almost seamlessly, and the rock wool 22 is sandwiched on the solid foundation 2. Since the floor material 5 is placed in the above, a heavy sound source 9 can be accommodated inside.

As a result of eliminating the concern about sound leakage from the sound source 9, it is possible to fully play a loud musical instrument even at midnight.

(Embodiment 2)
The second embodiment is mainly an upgraded version of the ventilation system 8 of the first embodiment. Since the basic structure of the soundproof chamber 1 is the same as that of the first embodiment, detailed description thereof will be omitted. FIG. 4 is a schematic view showing the ventilation system 8a of the soundproof chamber 1 according to the second embodiment, and FIG. 5 is a conceptual diagram of the vortex diode 83a according to the second embodiment. The solid line in FIG. 4 indicates the duct, and the broken line indicates the electric system.

As shown in FIG. 4, in the second embodiment, unlike the first embodiment, a ventilation device 14 including an air supply fan 14a and an exhaust fan 14b is provided at the lower part of the double wall 3. Considering that children are shorter than adults and are more susceptible to oxygen deficiency and carbon dioxide poisoning. As a result, the exhaust duct 84 can exhaust the air near the floor 5 in the soundproof chamber 1 to the outside of the soundproof chamber 1, and the air supply duct 82 can supply the outside air into the soundproof chamber 1, so that it is particularly safe for children. Can be secured.

Further, when the ventilation system 8a is stopped or when the wind is strong even during its operation, outside air may enter the soundproof room 1 through the exhaust duct 84. Therefore, an electric shutter is conventionally provided. However, it is not effective during a power outage. Therefore, the exhaust duct 84 of the second embodiment can intervene a vortex diode 83a that makes the line resistance larger when the air flows backward than when it flows forward. According to this, even when the ventilation system 8a is stopped or a power failure occurs, it is possible to reliably prevent the intrusion of outside air into the soundproof room 1.

The vortex diode 83a is a kind of fluid element, and its components include a cylindrical main body 831 and an inlet nozzle 832 connected in the central axial direction on the side surface of the main body 831. It is provided with an outlet nozzle 833 connected in the tangential direction on the peripheral surface of the main body 831.

In this vortex diode 83a, as shown by A → B in FIG. 5, when air flows in from the inlet nozzle 832 connected in the central axis direction of the side surface of the main body 831, almost no vortex is formed and a small shape resistance. Will only occur. On the contrary, as shown by B → A in FIG. 5, when air flows in from the outlet nozzle 833 connected in the tangential direction on the peripheral surface of the cylindrical main body 671, a vortex is surely formed, and the vortex is centrifugally formed. The force acts to reduce the pressure in the center, creating great resistance. As described above, the vortex diode 83a has a function similar to that of a diode in an electric system because the resistance becomes small when a fluid flows in from one of them and the resistance becomes large when a fluid flows in from the other.

The ventilation system 8a of the second embodiment will be described below.

Here, as shown in FIG. 4, in the space between the inner door 6b2 and the outer door 6b1 of the double door 6b, for example, sensors 603 to 606 which are photo interrupters composed of a pair of a light emitting part and a light receiving part are placed. Two pairs are provided for each of the high and low ranks. The higher sensors 603 and 605 are positioned based on the height of the adult M1 and the lower sensors 604 and 606 are positioned based on the height of the kindergarten and lower grade children M2, both of which are tall. It can be adjusted. In the ventilation system 8a of the second embodiment, the air filter 81 passes through the air supply duct 82 and the air supply fan 14a enters the soundproof room 1 according to the number of adults M1 and children M2 housed in the soundproof room 1. The amount of air supplied and the amount of air discharged from the soundproof chamber 1 through the exhaust duct 84 to the vortex diode 83a by the exhaust fan 14b can be adjusted to ventilate the inside of the soundproof chamber 1. The 14a and the exhaust fan 14b are integrated to form the ventilation device 14. The air filter 81 removes particles such as cedar pollen, which is a causative substance of pollinosis, and PM2.5, which is a causative substance of air pollution.

Here, too, a “strong” or “weak” selection switch 602 is provided separately from the power switch 601 of the ventilation device 14. The power switch 601 and the selection switch 602 and the sensors 603 to 606 are electrically connected to the air supply fan 14a and the exhaust fan 14b through the control panel 600.

The control panel 600 here is different from that of the first embodiment, and has a memory, a calculation function, a determination function, and the like. Then, the number composition of adults and children passing through the double door 6b is calculated from the count values of the sensors 603 to 606, and this calculated value corresponds to the set value 1 (first set value) of the first embodiment. ) Is reached, the selection switch 602 is automatically switched from "weak" to "strong". On the other hand, when the calculated value falls below the set value 1 again, the selection switch 602 is automatically switched from "strong" to "weak". When the calculated value reaches the set value 2 (corresponding to the second set value) of the first embodiment, a buzzer sounds and the double door 6b is automatically prohibited from closing by a lock mechanism (not shown). It is designed to do.

6 and 7 are flowcharts showing an operation example of the ventilation system 8a of the second embodiment. In FIG. 6, when the user or the owner turns on the power switch 601, the operation of the control panel 600 causes the selection switch 602, the sensors 603 to 606, and the number of adults and the number of children stored in the memory. Each is reset (step S1). That is, the power switch 601 is "off", the selection switch 602 is "weak", and the sensors 603 to 606 are all "off". The number of adults and the number of children stored in the memory are both 0.

Then, the number of adults and children entering and exiting the soundproof room 1 is detected (step S2). In FIG. 7, it is determined whether the sensor 603 at a higher position on the outer door 6b2 side of the double door 6b is “on” (step S201). Then, when the sensor 603 is turned "on", it is determined whether the sensor 605 at a higher position on the inner door 6b1 side is turned "on" (step 202). When the sensor 605 is turned "on", one adult is added (step S203). One adult is subtracted in the reverse order (steps S211 to S213).

It is determined whether the lower sensor 604 on the outer door 6b2 side of the double door 6b is "on" (step S221). Then, when the sensor 604 is turned "on", it is determined whether the sensor 606 at the lower position on the inner door 6b1 side is turned "on" (step 222). When the sensor 606 is turned "on", one child is added (step S223). One child is subtracted in the reverse order (steps S231-S233).

Returning to FIG. 6, the required ventilation volume Q is calculated by the following equation (step S3).
Ventilation volume Q = 20 * Number of adults N1 + 10 * Number of children N2
Is. The basis is based on the Ministry of Education, Culture, Sports, Science and Technology "Survey Research Report on Exhaust Equipment of School Facilities". Then, it is determined whether the ventilation volume Q is larger than the set value 1 (step S4). When the ventilation volume Q becomes larger than the set value 1, the selection switch 602 automatically switches from "weak" to "strong" (step S5). Further, it is determined whether the ventilation volume Q is larger than the set value 2 (step S6). When the ventilation volume Q becomes larger than the set value 2, the buzzer sounds, the double door 6b does not close, and so-called entry restriction is performed (step S7). It is determined whether the user or the owner has turned off the power switch 601 to release the restriction (step S8). When the power switch 601 is turned "off" and the restriction is released, the automatic operation ends at that point. This makes it possible to more reliably avoid oxygen deficiency and carbon dioxide poisoning due to insufficient ventilation.

Although it is not the soundproof room 1, the present inventor has experience in arranging the photovoltaic power generation panel 11 on the roof 10 in the same wooden house, and in order to improve the power generation efficiency, the photovoltaic power generation panel 11 I thought about washing with water. Specifically, the rainwater from the roof 10 can be used as washing water for the photovoltaic power generation panel 11 via the rainwater tank 12. A schematic diagram showing the electric system and the water system in that case is shown in FIG. The broken line in FIG. 8 indicates the electric system, and the alternate long and short dash line indicates the water system.

As shown in FIG. 8, the direct current (DC) generated by the photovoltaic power generation panel 11 is converted into alternating current (AC) by the inverter 501, and the watering device 13, the ventilation device 14, and other electric devices (air conditioner) are converted by the switchboard 502. , Lighting, musical instruments, etc.). Here, the surplus power is stored in the storage battery 503 or is returned to the system via the watt-hour meter 504 and sold, while the insufficient power is supplied from the storage battery 503 or the watt-hour meter 504 is used. Power will be supplied from the system via the system.

Rainwater collected from the roof 10 by a gutter (not shown) is temporarily stored in a rainwater tank 12 provided near the ground GL, and is sprinkled as cleaning water for the photovoltaic power generation panel 11 by the sprinkler 13 at a predetermined timing. To do so. Predetermined timing, it may be one of irregularly like when solar panels 11 is soiled with yellow sand and bird droppings, or may be a regularly.

This watering has the effect of keeping the room cool to some extent in the summer, and has the effect of melting the snow cover to some extent in the winter. If the amount of water sprinkled cannot keep up with the water stored in the rainwater tank 12, tap water or well water can be used, and if the water stored in the rainwater tank 12 is surplus, it can be used for watering the garden. I have to. The photovoltaic power generation panel 11 is placed on the roof 10, and can be easily removed when the roof 10 is repaired, and the repair can be easily performed.

In the above-described first and second embodiments, the soundproof room 1 is illustrated as a music rental studio, but other soundproof rooms and private diesel generators for the purpose of breeding pets such as large dogs and dogs that make a loud noise. It may be a soundproof room having the purpose of incorporating mechanical equipment that emits noise, such as a machine or a machine tool.

Further, in the first and second embodiments, the soundproof room 1 is composed of independent houses, but it does not necessarily have to be a completely independent house. For example, the first floor of the main house may be the soundproof room 1. Further, instead of the wooden house, it may be a room of a concrete house or an apartment / condominium. In that case, it is necessary to take measures against moisture in the summer and measures against drying in the winter.

Further, in the above-described first and second embodiments, glass wool is used as the first and second soundproofing materials, and rock wool is used as the third soundproofing material. It may be a material having the above performance. However, high-density materials such as lead, which may adversely affect the health and environment of workers, shall not be used at all.

Further, since glass wool and rock wool have excellent heat insulating performance, the room temperature can be maintained almost constant even if the outside air temperature fluctuates to some extent, which is advantageous for storing musical instruments and the like.

However, the ventilation device 14 alone may not be sufficient depending on conditions such as when the outside air temperature becomes higher or lower, when there is heat generated from musical instruments or lighting, or when a person is in the room. In that case, an air conditioner (not shown) may be used. However, since the air conditioner has almost no ventilation function, the ventilation systems 8 and 8a of the soundproof room 1 are indispensable.

Further, in the first and second embodiments, the triple glass window 7 is provided, but at least a single-layer glass window 7 may be provided. Transparent acrylic may be used instead of this glass. The double wall 3 and the double ceiling 4 may be further multiplexed depending on the soundproofing performance, or conversely, may be a single-layer wall or ceiling.

Further, in the first embodiment, although it is divided into two types of persons, an adult and a child, it may be divided into three or more types of persons including an intermediate between an adult and a child. Further, the user or the owner is supposed to operate the power switch 601 and the selection switch 602, but if a security surveillance camera 607 (see FIG. 4 of the second embodiment) is installed indoors or outdoors, it is used. It may be used to instruct an adult in the room to operate from the outside.

Further, also in the second embodiment, it may be divided into three or more types including an intermediate between an adult and a child, but the number of sensors may increase and the setting and operation thereof may become complicated. In that case, the image pattern by the surveillance camera 607 may be analyzed by AI technology such as deep learning. Further, the sensor is not limited to the photo interrupter, and for example, a load cell may be used to judge an adult and a child by the weight difference. Further, an ultrasonic sensor, a magnetic sensor, or the like may be used.

Further, in the first and second embodiments, the ventilation device 14 is assumed to be integrated with the air supply fan 14a and the exhaust fan 14b, but may be provided separately. In that case, for example, the mounting position of the air supply fan 14a may be the double wall 3 or the double ceiling 4, and the mounting position of the exhaust fan 14b may be the lower part of the double wall 3, or vice versa. .. Further, a plurality of ventilation devices 14 may be provided for parallel operation or series operation.

Further, in the first and second embodiments, the ventilation systems 8 and 8a are incorporated at the time of new construction of the soundproof room 1, but the ventilation systems 8 and 8a may be retrofitted to the existing soundproof room. Good. Further, it is not necessary to equip the ventilation systems 8 and 8a completely, and a part of them may be equipped, or an option may be additionally equipped. For example, a soundproof room for pets may be provided with only one of an air supply fan and an exhaust fan, although it is related to the required soundproof performance. Further, depending on the environment, the air fill of the air supply duct may be omitted. Furthermore, a safer system can be constructed by providing an extension duct for the exhaust fan and opening it to the part where the child is.
