Figures 1 to 11 show a soundproof room and an air conditioning system for the soundproof room in a first embodiment of the present invention. As shown in Figures 1 to 4, the first soundproof room 11 is formed by a housing 12 and a door 13, has a space that people can enter, and is installed in places where various people pass through, such as inside a train station, an airport, a commercial facility, an exhibition center, an outdoor plaza, inside a store, a hotel, an apartment building, or an office. In addition, the soundproof room 11 can send and receive data to and from external devices via a network such as the Internet. A user using the soundproof room 11 can, for example, use a videoconferencing terminal installed in the soundproof room 11 to hold a videoconference with a user using an external device having a videoconferencing function.

The housing 12 is made of materials such as metal, wood, or resin, and is formed as a rectangular parallelepiped with a large overall height dimension, with an opening for users to enter and exit on one side, the front (Figure 1). Casters 14 are provided on the four corners of the bottom of the housing 12, and adjusters 15 are provided in their vicinity. After using the casters 14 to move the soundproof room 11 to the installation location, the installer of the soundproof room 11 can fix the soundproof room 11 in a fixed position by adjusting the length of the adjusters 15 so that it is equal to the distance between the bottom of the soundproof room 11 and the floor.

The sound-absorbing material 12a is provided on the inside of the housing 12, so that the voices of users inside the soundproof room 11 and users using external devices are unlikely to leak out of the soundproof room 11. Therefore, even if the soundproof room 11 is installed in a public place where an unspecified number of people pass by, users can safely talk about highly confidential information. In addition, the specifications of the floor material 12b are a double floor structure in which multiple beams are placed inside the framed base material to form an underfloor space between the upper and lower floorboards, ensuring the strength necessary for people to enter and exit and to support the sofa 16 that serves as a seat. Furthermore, from the perspective of disaster prevention, non-flammable materials are used for the sound-absorbing material 12a on the inner wall surface and the tile material 12c laid on the floor surface.

The sofa 16 is formed with a width that allows one adult to sit comfortably, and the backrest 16a is placed against one of the opposing inner wall surfaces of the housing 12, while a table 17 that can be used while seated is attached in a cantilevered manner to the other inner wall surface. The dimensions of the height, width, and depth of the interior space are set so that when the sofa 16 and table 17 are placed, they do not impede the user's entry and exit, and do not impair the convenience of the user when working or carrying out activities.

The door 13 is connected to the housing 12 so that it can close the opening of the housing 12, and is configured to be able to be opened and closed around the joint with the housing 12 by operating the handle 13a. The door 13 is provided with door glass 13b, which allows the inside of the soundproof room 11 to be viewed from the outside.

A lock (not shown) is provided between the housing 12 and the door 13, and is switched between an unlocked state in which the door 13 can be opened and a locked state in which the door 13 cannot be opened under the control of a control unit (CPU) built into the housing 12. The lock is controlled to unlock or lock the soundproof room 11 by switching between the unlocked and locked states by a user's operation from inside the housing 12, or by switching by remote control.

In addition, an operation reception unit 18 that receives user operations is provided on the front side of the housing 12. The operation reception unit 18 is, for example, a display with a touch panel, and receives one of 30 minutes, 60 minutes, and 90 minutes as the planned use time input by the user. Furthermore, reservations can be made by specifying the date and time in advance from an information terminal such as a smartphone. When the reserved time arrives, the user touches the operation reception unit 18 of the soundproof room 11 that he or she has reserved, and reads the QR code (registered trademark) displayed on the screen with the information terminal. Then, when the necessary authentication based on the user identification information is completed in the management device (server) on the network, the soundproof room 11 is unlocked and the user can enter the room. The fee to be paid is determined according to the planned use time, and power is supplied to the electronic devices installed inside the soundproof room 11 from the completion of the payment until the planned use time has elapsed.

The electronic devices function by receiving power from a power supply unit built into the housing 12, and include permanently installed video conference equipment 19, lighting 20, surveillance cameras 21, speakers 22, and air conditioning equipment installed on the ceiling 12d of the housing 12, as well as computers or mobile terminals brought in by users. The air conditioning equipment ventilates the interior space of the soundproof room and adjusts the internal temperature, and examples of this include an integrated air conditioner (air conditioner) 23 for heating and cooling installed on the floor, and a fan 24 installed on the ceiling 12d. The specific configuration of the air conditioning equipment will be described later.

When the control unit receives an instruction from a management device that has completed user authentication while the power supply unit is wired to an external power outlet, the control unit controls the power supply unit to start supplying power to various electronic devices such as air conditioning equipment. In other words, these devices operate under the control of the control unit from the completion of payment until the scheduled usage time has elapsed. In addition, the user can receive power as needed using the connection port 25 of the electronic device installed in the room.

Here, an automatic fire extinguishing device 26 is installed on the ceiling 12d of the soundproof room 11 as one of the disaster prevention facilities. The automatic fire extinguishing device 26 is a downward discharge type fire extinguishing device (sprinkler) that does not require a power source, and is integrally equipped with an extinguishing agent container 27 filled with an extinguishing agent, and a discharge nozzle 28 that is installed at the center of the lower end of the extinguishing agent container 27 and can discharge the extinguishing agent into the room when detected by a built-in heat detector. A low melting point metal is used for the heat detector, and in the event of an emergency when a fire breaks out, when the heat collecting plate at the lower end of the discharge nozzle 28 detects heat from the fire source, the low melting point metal melts and the pressurized gas inside the container blows off the sealing plug and the heat collecting plate, starting the discharge of the extinguishing agent.

The automatic fire extinguishing device 26 is installed in a position that takes into consideration the placement of the lighting 20, speaker 22, fan 24, various cover members 29, etc., so as not to impair the functionality of the soundproof room 11 (Figure 2). In particular, the position of the discharge nozzle 28, i.e., the position of the heat detection unit, and the position of the fan 24 are arranged side-by-side so that the rising air current formed by the operation of the fan 24 promotes the rise of heat from the fire source.

Incidentally, soundproof rooms 11 are required to have air conditioning that can provide a comfortable air environment under normal usage conditions without causing thermal discomfort to users working or doing activities inside the room. In particular, if soundproof rooms 11 are to be installed in public facilities such as train stations, it is expected that the temperature inside the rooms will be higher than the outside air temperature in summer. For this reason, an integrated air conditioner 23 is installed on the floor of the soundproof room 11 to prepare the room for cooling or heating.

Figures 5 to 10 show the first integrated air conditioner 23 applied to the first soundproof room and the air conditioning system for the soundproof room of the present invention. The integrated air conditioner 23 houses a refrigeration cycle for cooling and a PTC (Positive Temperature Coefficient) heater, which is a heating element, in the same cabinet. As shown in Figure 5, by operating the operation panel 30a provided on the front of the rectangular box-shaped cabinet 30, it is possible to select the operation mode of cooling or heating operation and input the set temperature and air volume. When installed in the soundproof room 11, the cabinet 30 has a height dimension that fits comfortably under the table 17, and has handles 30b on both the left and right sides that allow both hands to be placed on when transporting or installing.

On the front of the cabinet 30, an air outlet 30c for heating and cooling is provided on the upper side in the vertical direction sandwiching the operation panel 30a, and a front air intake 30d for taking in indoor air is provided on the lower side. In addition, a side air intake 30e for taking in indoor air is provided at the upper part of the left side of the cabinet 30 (Fig. 7). The top surface of the cabinet 30 is formed flat without through holes or unevenness as shown in Fig. 8, while the bottom surface, which is the installation surface of the cabinet 30, is provided with an exhaust port 30g at the end avoiding the bottom cover 30f as shown in Fig. 9. The exhaust port 30g is formed as a rectangular opening as a whole by arranging multiple long holes of a predetermined size in the front-rear direction, ensuring the ventilation of the exhausted warm air.

As shown in FIG. 10, inside the cabinet 30, a compressor 31 is placed at the bottom, and a condenser 33 corresponding to the position of the front intake 30d of the cabinet 30 and a condenser fan (not shown) are placed side by side on the rear side of the pedestal 32, which is assembled so as to straddle the compressor 31 by four support pillars 32a. In addition, a space for exhausting heat is formed on the right side of the pedestal 32, and an exhaust duct 34 is provided in this space.

The exhaust duct 34 is a tube with a rectangular cross section that extends vertically along the inner surface of the cabinet 30, and its upper end is formed with an arc-shaped inner surface 34a that takes in the horizontal airflow (hot air) from the condenser fan and changes it to a vertically downward flow, and its lower end is connected to the exhaust port 30g. Thus, the compressor 31, condenser 33, condenser fan, and exhaust duct 34 are mainly arranged in the lower half of the cabinet 30.

At the top of the cabinet 30, there are a control circuit for controlling the operating state of the cooling and heating functions, an evaporator fan 35 provided corresponding to the positions of the side air intake 30e and the air outlet 30c, and an evaporator 36 and a PTC heater 37 arranged side by side in the cabinet width direction upstream of the evaporator fan 35. In addition, directly below the evaporator 36, there is a processing unit 38 for collecting condensation water generated during cooling operation and evaporating the condensation water with the heat of the condenser 33.

When the integrated air conditioner 23 thus constructed is used, during cooling operation, the circuit of the PTC heater 37 is turned off, and the refrigeration cycle is operated by driving the compressor 31. As a result, the refrigerant is made high-pressure by the compressor 31 and sent to the condenser 33, where it is condensed and dissipates heat. Furthermore, the low-temperature refrigerant that has passed through the expansion valve is sent to the evaporator 36, where it absorbs heat (cooling effect), becomes low-pressure, and is returned to the compressor 31.

Here, the air taken in from the side air intake 30e by the operation of the evaporator fan 35 is cooled by the evaporator 36 and becomes cold air and is sent out from the air outlet 30c. Meanwhile, the heat of the condenser 33 becomes warm air by the operation of the condenser fan and flows into the upper part of the exhaust duct 34, and flows vertically downward along the arc inner surface 34a of the exhaust duct 34, and is sent out from the exhaust port 30g. In this way, the cooling operation of the integrated air conditioner 23 is performed. At this time, the condensed water generated by the evaporator 36 is captured in the processing unit 38 while naturally falling, and then evaporated by the heat of the condenser 33, and is processed internally without being discharged to the outside.

During heating operation, the refrigeration cycle is stopped and the circuit of the PTC heater 37 is turned on. This causes the air taken in from the side air intake 30e to be heated by the operation of the evaporator fan 35, which is also used in heating operation, and the air is sent out from the air outlet 30c as warm air. In this way, the heating operation of the integrated air conditioner 23 is performed. The PTC heater 37 is a heater that utilizes the PTC characteristic, in which the resistance value increases as the temperature increases, so once a certain temperature is reached, the temperature will not increase any further, preventing overheating and ensuring energy saving and safety.

In the soundproof room 11 thus formed, the configuration of the floor material 12b and the arrangement of various air conditioning equipment are optimized to maximize the air conditioning effect. Specifically, as shown in FIG. 11, the integrated air conditioner 23 is placed directly under the table 17, with the back of the cabinet 30 aligned with the inner wall surface of the housing 12, and the left side of the cabinet 30 aligned with the inner wall surface of the housing 12 to which the door 13 is connected (FIG. 3), that is, in a state where it is placed close to the corner on the entrance side, and a fixing bracket (not shown) is used to prevent it from falling over. In addition, the fan 24 provided on the ceiling 12d is positioned so as to be located directly above the sofa 16. As a result, the cold or warm air sent into the room from the air outlet 30c, in combination with the suction force of the operating fan 24, forms a gentle upward air current as shown by arrow A in FIG. 11, and is released to the outside from the ceiling 12d.

On the other hand, an opening (not shown) is provided in the floor material 12b of the housing 12 corresponding to the position and size of the exhaust port 30g of the integrated air conditioner 23, and this opening forms an air passage 39 that connects the upper and lower surfaces of the upper and lower floor panels 12e, 12f. As a result, the warm air blown out from the exhaust port 30g during cooling operation passes under the floor and is released onto the floor surface where the soundproof room 11 is installed, as shown by arrow B in Figure 11.

In this way, in the first configuration, an opening is formed in the floor of the soundproof room 11 in which the integrated air conditioner 23 is installed, through which the hot air blown out from the exhaust port 30g of the integrated air conditioner 23 can be discharged to the outside. This makes it possible to separate the exhaust heat of the refrigeration cycle from the cold air without diffusing it inside the room, and it is possible to easily realize an air environment with little energy loss. Moreover, even if the soundproof room 11 is installed next to the surrounding walls or other soundproof rooms, the exhaust air blown out from under the floor flows without clogging, and does not cause discomfort to people nearby or passersby, so it has an environmentally friendly effect. In addition, a fan 24 is provided on the ceiling 12d, and its operation forms an updraft in the soundproof room 11, which promotes the rise of the cold air from the integrated air conditioner 23, making it possible to suck up the air throughout the room and air condition it, and it is possible to adjust the room temperature uniformly without complex control.

In addition, the control unit in the soundproof room 11 receives authentication of the reservation user made by the management device and controls the start of operation of the integrated air conditioner 23 and the fan 24, eliminating the inconvenience to the user, such as the time and effort required to operate the air conditioning equipment, and making it possible to operate the soundproof room 11 more economical. In other words, a structure and air conditioning system for the soundproof room 11 that can provide excellent air conditioning functionality with a simple configuration is realized, thereby promoting comfortable use of the soundproof room 11 in the various environments in which it is installed.

Furthermore, when a set of sofas 16 and a table 17 are placed in the soundproof room 11, the integrated air conditioner 23 is positioned directly below the table 17 and the fan 24 is positioned directly above the sofa 16, so that the wind sent out from the air outlet 30c of the integrated air conditioner 23 forms a gentle upward air current with optimal wind speed and airflow spread, realizing a comfortable indoor space without the discomfort of wind directly hitting the skin. Moreover, the integrated air conditioner 23 is positioned so that one side of the cabinet 30 is aligned with the inner wall surface of the housing 12 to which the door 13 is joined, so that not only can it respond sensitively to the change in temperature in the room due to the opening and closing of the door 13, but it can also maximize the space under the feet of a seated user. Furthermore, by placing the integrated air conditioner 23 under the table 17, its presence is not an issue, and the indoor space can be beautifully designed.

In addition, the soundproof room 11 is equipped with an integrated automatic fire extinguishing device 26 including a fire extinguishing agent container 27 on the ceiling 12d, so that initial fires can be quickly extinguished without relying on human operation. Moreover, a fan 24 installed on the ceiling 12d at the same height as the automatic fire extinguishing device 26 creates an updraft in the room when activated, accelerating the rise of heat from the fire source and enabling quick and reliable heat detection, which in turn allows the air conditioning function of the soundproof room 11 to be maximized.

In the first configuration, an example was shown in which the exhaust port 30g of the integrated air conditioner 23 was provided on the bottom surface of the cabinet 30, but if sufficient space can be secured for the installation location of the soundproof room 11, it is not necessarily necessary to use an underfloor exhaust structure. In addition, since soundproof rooms are installed in a variety of locations, there is always a demand for this type of air conditioning system to operate more efficiently according to the required cooling capacity, that is, to save energy. Therefore, below, as a modified example, the configuration and function of an integrated air conditioner that is integrally attached to the wall separating the indoor and outdoor areas of the soundproof room and whose exhaust port can be exposed to the outside will be described.

Figures 12 to 18 show a soundproof room and an air conditioning system for the soundproof room in a second embodiment of the present invention. In the following description, the same components as those shown in the first embodiment are given the same reference numerals and detailed description is omitted.

As shown in Figs. 12 to 15, the second all-in-one air conditioner 51 houses a refrigeration cycle for cooling and a PTC heater, which is a heating element, in the same cabinet, and by operating the operation panel 52a provided on the front of the rectangular box-shaped cabinet 52, it is possible to select the operation mode of cooling or heating and input the set temperature and airflow. The cabinet 52 is formed with height and depth dimensions such that, when installed in a soundproof room where it will be used, the front side, which will be placed inside the room, fits comfortably under a table, and the rear side, which will be placed outside the room, can achieve the intake and exhaust functions.

As shown in Fig. 12, the front surface of the cabinet 52 is provided with an air outlet 52b for heating and cooling on the upper side in the vertical direction sandwiching the operation panel 52a, and a front air intake 52c for taking in indoor air on the lower side. In addition, as shown in Fig. 13, an exhaust outlet 52d is provided on the right side of the cabinet 52, and as shown in Fig. 14, a side air intake 52e is provided on the left side of the cabinet 52 in a position opposite the exhaust outlet 52d.

As shown in FIG. 15, the inside of the cabinet 52 is divided into an indoor heat exchange chamber 53 and an outdoor heat exchange chamber 54 in the depth direction (left and right direction in FIG. 15) by the provision of a partition plate 52f. As main components, the indoor heat exchange chamber 53 has a compressor 55 disposed at the bottom, an evaporator 57 and a PTC heater 58 disposed on a stand 56 corresponding to the position of the air outlet 52b, and an evaporator fan 59 disposed at the back of these, arranged side by side. In addition, a processing unit 60 is provided directly below the evaporator 57 to collect condensation water generated during cooling operation.

On the other hand, in the outdoor heat exchange chamber 54, a condenser 62 and a condenser fan 63, which is a blower, are arranged on a stand 61 in the space between the side intake 52e and the exhaust 52d, with the orientation taking into consideration proper ventilation. As a result, when the condenser fan 63 is operated, air is taken in from the upstream side intake 52e, passes through the condenser 62 while flowing in the direction along the plate surface of the partition plate 52f (the direction of the arrow in Figure 15), and is then sent out to the outside from the downstream exhaust 52d.

When the integrated air conditioner 51 thus constructed is used, during cooling operation, the circuit of the PTC heater 58 is turned off, and the refrigeration cycle is operated by driving the compressor 55. As a result, the refrigerant is brought to a high pressure state by the compressor 55 and sent to the condenser 62, where it is condensed and dissipates heat. Furthermore, the low-temperature refrigerant that has passed through the expansion valve is sent to the evaporator 57, where it absorbs heat (cooling effect), is returned to a low pressure state, and is returned to the compressor 55.

Here, the air taken in from the front air intake 52c by the operation of the evaporator fan 59 is cooled by the evaporator 57 and sent out from the air outlet 52b as cold air. Meanwhile, the heat of the condenser 62 is turned into warm air by the operation of the condenser fan 63 and sent out from the exhaust port 52d. In this way, the cooling operation of the integrated air conditioner 51 is performed. At this time, since the back wall 54a and the partition plate 52f of the outdoor heat exchange chamber 54 are parallel to each other, the air flowing through the space between them is rectified, and as a result, a linear air flow is formed from the side air intake 52e toward the exhaust port 52d. In addition, the condensation water generated by the evaporator 57 is captured in the processing unit 60 while naturally falling, and then led to the outdoor heat exchange chamber 54 where it is evaporated by the heat of the condenser 62, and is processed inside without being discharged to the outside.

During heating operation, the refrigeration cycle is stopped and the circuit of the PTC heater 58 is turned on. This causes the air taken in from the front air intake 52c to be heated by the operation of the evaporator fan 59, and the air is blown out from the air outlet 52b as warm air. In this way, the integrated air conditioner 51 performs heating operation.

Figures 16 to 18 show a soundproof room to which the integrated air conditioner 51 is applied. The second soundproof room 71 basically has the same configuration and function as the first embodiment, but as shown in Figures 17 and 18, the wall of the housing 72 has a wall hole 73 corresponding to the external shape of the cabinet 52 in the wall 72a on the opposite side (rear side) from the door 13 side of a pair of opposing walls.

When the all-in-one air conditioner 51 is airtightly attached to the wall hole 73 with the exhaust port 52d exposed to the outside of the housing 72, the condenser fan 63 allows the air in the outdoor heat exchange chamber 54 to flow in a direction along the plate surface of the partition plate 52f, and the hot air blown out from the exhaust port 52d can be released in a direction along the wall (outer wall surface) 72a of the housing 72. At this time, the cabinet 52 is arranged so that the partition plate 52f is located in a position corresponding to the wall hole 73, and the indoor heat exchange chamber 53 is placed on the floor surface along the inner wall surface of the housing 72; in other words, the air outlet 52b is located directly under the table 17, and the cabinet 52 is attached to the wall hole 73 with a fixing bracket (not shown) to prevent it from falling off.

As a result, the cool or warm air sent into the room from the air outlet 52b, in combination with the suction force of the operating fan 24, forms a gentle upward air current as shown by arrow C in FIG. 17, and is released to the outside from the ceiling 12d. On the other hand, the warm air blown out from the exhaust outlet 52d during cooling operation is released from the exhaust outlet 52d along the wall 72a of the housing 72 at the back side of the housing 72 while maintaining the airflow speed inside the outdoor heat exchange chamber 54 as shown by arrow D in FIG. 18.

In this way, in the second configuration, the integrated air conditioner 51 is attached to the wall hole 73 provided in the wall 72a opposite to the door 13 side among the walls forming the housing 72 of the soundproof room 71, and in this mounted state, the exhaust port 52d is exposed to the outside of the housing 72, so that it is possible to separate the exhaust heat of the refrigeration cycle from the cold air without diffusing it inside the room, and an air environment with less energy loss can be easily realized. In addition, since the hot air blown out from the exhaust port 52d is formed to be able to be discharged in a direction along the wall 72a of the housing 72, even if the soundproof room 71 is installed next to the surrounding walls or other soundproof rooms, it is possible to suppress the occurrence of a so-called short circuit in which the exhaust air is stagnated and sucked back into the device, and the balance of the refrigeration cycle is maintained, which contributes to stabilizing the air conditioning capacity. In other words, a structure and air conditioning system of the soundproof room 71 that can exhibit excellent air conditioning function with a simpler configuration is realized, and thus it is possible to promote comfortable use of the soundproof room 71 in various environments in which it is installed.

The present invention is not limited to the above-mentioned embodiment, and the soundproof room can be equipped with various necessary equipment in addition to air conditioning and disaster prevention equipment, and the installation location can be a moving body such as a train car, bus, taxi, or airplane. The shape of the housing is not limited to a rectangular parallelepiped, but can be cylindrical, and can be formed with a space that can accommodate not only one person but two or more people, as long as the advantages of a mobile, portable soundproof room are not lost. In this case, the configuration of the equipment and air conditioning equipment can be changed to the extent that the user can comfortably carry out work or activities in the room without feeling any airflow or discomfort.

Furthermore, the fan is provided on the ceiling surface, i.e., on the same surface as the surface on which the automatic fire extinguishing device is attached, to provide a remarkable air conditioning effect not only in terms of disaster prevention but also in normal use, but is not limited to this, and can be appropriately changed, such as provided on the upper part of the side wall surface, depending on the environment in which the soundproof room is installed. In addition, various specifications for the integrated air conditioner can be adopted as long as they have an exhaust port on the bottom or side, and the arrangement of the equipment stored in the cabinet can also be appropriately changed. In addition, in the first configuration, the shape of the exhaust duct can be, for example, not only formed by the inner surface of the arc, but also formed by an inclined or upright surface. Furthermore, the opening provided in the floor material can be of any size and shape as long as it is provided in correspondence with the exhaust port of the integrated air conditioner, and a large number of dot-shaped or slit-shaped holes of a certain size can be provided in consideration of breathability.

In the second configuration, the partition plate is not particularly limited in shape as long as it has a plate surface large enough to ensure ventilation within the heat exchange chamber, and holes can be provided for installing refrigerant pipes, electrical circuits, etc. Furthermore, if the air in the outdoor heat exchange chamber can flow in a direction along the plate surface of the partition plate, the exhaust port can be provided not only on the side but also on the top, for example. In this case, compared to a general air conditioner that exhausts from the rear, there are no quality problems such as inability to operate due to installation location conditions, such as near a wall in a station where an unspecified number of people pass by, or a shortened lifespan due to continuous operation under overload of the compressor, which is extremely beneficial.
