Embodiments for Carrying Out the Invention

[0010] Figs. 1 to 11 show a soundproof room and an air conditioning system for the soundproof room in a first exemplary embodiment of the present invention. The first soundproof room 11 is formed by a housing 12 and a door 13, as shown in Figs. 1 to 4, and has a space into which a person can enter. For example, it is installed in various places where people pass, such as inside a station building, an airport, a commercial facility, an exhibition hall, an outdoor square, the inside of a store, a hotel, an apartment building, or an office. In addition, the soundproof room 11 can transmit and receive data to and from external devices via a network such as the Internet. A user who uses the soundproof room 11 can hold a video conference with a user who uses an external device having a video conferencing function, for example, using a video conferencing terminal installed in the soundproof room 11.

[0011] The housing 12 is made of members such as metal, wood, or resin, and is formed as a rectangular parallelepiped with a large height dimension as a whole. An opening for the user to enter and exit is provided on the front surface (FIG. 1), which is one side surface thereof. Further, casters 14 are provided at the four corners of the bottom surface of the housing 12, and adjusters 15 are provided in the vicinity thereof. After the installer of the soundproof room 11 moves the soundproof room 11 to the installation location using the casters 14, the soundproof room 11 can be fixed in place by adjusting the length of the adjuster 15 so that it is equal to the distance between the bottom surface of the soundproof room 11 and the floor surface.

[0012] A sound-absorbing material 12a is provided inside the housing 12, and voices spoken by the user inside the soundproof room 11 and voices emitted by the user using external equipment are less likely to leak outside the soundproof room 11. Therefore, even when the soundproof room 11 is installed in a public place where an unspecified number of people pass by, the user can talk about highly confidential content with confidence. Further, the specification of the floor material 12b has a double-floor structure in which a floor space is formed between the upper and lower floor boards by interposing a plurality of beams inside the framed base material, and the strength required for supporting the entry and exit of people and the sofa 16 serving as a seat is ensured. Furthermore, from the perspective of disaster prevention, non-combustible materials are used for the sound-absorbing material 12a on the inner wall surface and the tile material 12c laid on the floor surface.

[0013] The sofa 16 is formed to have a width that allows an adult to sit with a little extra space, and the backrest 16a is arranged in contact with one of the inner wall surfaces of the housing 12 facing each other. A table 17 that can be used in a seated state is attached to the other inner wall surface in a cantilever manner. The indoor space has dimensions of height, width, and depth set to such a size that a set of the sofa 16 and the table 17 are arranged without hindering the entry and exit of the user and without impairing the convenience of the user who performs work or activities.

[0014] The door 13 is coupled to the housing 12 so as to be able to close the opening of the housing 12, and is configured to be openable and closable about the coupling portion with the housing 12 by operating the handle 13a. A door glass 13b is provided on the door 13, enabling the interior of the soundproof room 11 to be visible from the outside.

[0015] A lock (not shown) is provided between the housing 12 and the door 13, and under the control of a control unit (CPU) incorporated in the housing 12, it switches between an unlocked state where the door 13 can be opened and a locked state where the door 13 cannot be opened. The lock is controlled to unlock or lock the soundproof room 11 by the user operating it from the inside of the housing 12 to switch between the unlocked state and the locked state, or by remote operation.

[0016] Also, an operation reception unit 18 for receiving 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 any one of the times of 30 minutes, 60 minutes, and 90 minutes as the planned usage time input by the user. Furthermore, a reservation can also be made in advance by specifying a date and time 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 the user 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 becomes accessible. The fee to be paid is determined according to the planned usage time, and power is supplied to the electronic devices provided inside the soundproof room 11 until the planned usage time elapses after the payment is completed.

[0017] The electronic device receives power supply from a power supply unit incorporated in the housing 12 and exhibits functions, including permanently installed video conferencing equipment 19, lighting 20 installed on the ceiling 12d of the housing 12, a surveillance camera 21, a speaker 22, air conditioning equipment, as well as a computer or a mobile terminal brought in by the user. The air conditioning equipment ventilates the internal space of the soundproof room and adjusts the internal temperature. Examples include an integrated air conditioner (air conditioner) 23 installed on the floor for heating and cooling, and a fan 24 installed on the ceiling 12d. The specific configuration of the air conditioning equipment will be described later.

[0018] When the control unit receives an instruction from a management device for which user authentication has been completed while the external power outlet and the power supply unit are wired, it performs control to start the power supply by the power supply unit to various electronic devices such as the air conditioning equipment. That is, these devices operate based on the control by the control unit until the usage scheduled time elapses after the settlement is completed. Also, the user can receive power supply as needed by using the connection port 25 of the electronic devices provided in the room.

[0019] Here, an automatic fire extinguishing device 26 is provided on the ceiling 12d of the soundproof room 11 as one of the fire prevention facilities. The automatic fire extinguishing device 26 is a downward discharge type fire extinguishing device (sprinkler) that does not require power supply, and integrally includes a fire extinguishing agent container 27 filled with a fire extinguishing agent, and a discharge nozzle 28 provided at the center of the lower end of the fire extinguishing agent container 27 and capable of discharging the fire extinguishing agent into the room upon receiving the detection of a built-in heat sensing unit. A low melting point metal is used for the heat sensing unit. In the event of a fire, when the heat collecting plate at the lower end of the discharge nozzle 28 senses the heat from the fire source, the low melting point metal melts, and the pressurized gas in the container blows off the sealing plug and the heat collecting plate, and the discharge of the fire extinguishing agent begins.

[0020] The automatic fire extinguishing device 26 is set at its mounting position in consideration of the arrangements of the lighting 20, the speaker 22, the fan 24, various cover members 29, etc. so as not to impair the functionality of the soundproof room 11 (Fig. 2). In particular, the position of the discharge nozzle 28, that is, the position of the heat detection part and the position of the fan 24 are provided so as to be side by side with each other in such a relationship that the upward airflow formed by the operation of the fan 24 promotes the rise of heat from the fire source.

[0021] By the way, in the soundproof room 11, in the normal use state, air conditioning that can provide a comfortable air environment without giving thermal discomfort to the users who work and carry out activities indoors is desired. In particular, considering installing the soundproof room 11 in public facilities such as inside a station, it is also assumed that the temperature will be higher than the outside air temperature in summer. For such reasons, an integrated air conditioner 23 for conditioning the room to a state suitable for cooling or heating is installed on the floor of the soundproof room 11.

[0022] Figs. 5 to 10 show a first integrated air conditioner 23 applied to the first soundproof room and the air conditioning system of 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 for heating in the same cabinet. As shown in Fig. 5, by operating an operation panel 30a provided on the front surface of a rectangular box-shaped cabinet 30, it is possible to select the operation mode of the cooling operation or the heating operation, input the set temperature, and the air volume. The cabinet 30 has a height dimension that fits well under the table 17 when installed in the soundproof room 11, and has handles 30b on both left and right side surfaces that allow both hands to be placed when carrying or installing.

[0023] On the front surface of the cabinet 30, an air outlet 30c for air conditioning is provided above the operation panel 30a in the vertical direction, and a front air inlet 30d for taking in indoor air is provided below it. Also, on the left side surface of the cabinet 30, a side air inlet 30e for taking in indoor air is provided at the upper part (Fig. 7). As shown in Fig. 8, the upper surface of the cabinet 30 is formed in a flat shape without through holes or irregularities. On the other hand, as shown in Fig. 9, an exhaust port 30g is provided at the end avoiding the bottom cover 30f on the bottom surface which is the installation surface of the cabinet 30. The exhaust port 30g is formed in a rectangular opening shape as a whole by arranging a plurality of elongated holes of a predetermined size in the front-rear direction, ensuring the air permeability of the warm air to be discharged.

[0024] Inside the cabinet 30, as shown in Fig. 10, a compressor 31 is arranged at the lower part, and a condenser 33 corresponding to the position of the front air inlet 30d of the cabinet 30 and a condenser fan (not shown) are arranged side by side on a pedestal 32 assembled so as to straddle the compressor 31 by four support columns 32a. Also, a heat exhaust space is formed on the right side of the pedestal 32, and an exhaust duct 34 is provided in this space.

[0025] The exhaust duct 34 is formed in a tubular shape with a rectangular cross-section extending in the vertical direction along the inner surface of the cabinet 30, and has an arc inner surface 34a at the upper end for taking in the horizontal airflow (warm air) from the condenser fan and changing it to a downward vertical flow, and the lower end is connected to the exhaust port 30g. Thus, mainly the compressor 31, the condenser 33, the condenser fan, and the exhaust duct 34 are intensively arranged in the lower half of the cabinet 30.

[0026] At the upper part inside the cabinet 30, there are a control circuit for controlling the operation state of the air conditioner, an evaporator fan 35 provided corresponding to the positions of the side air intake 30e and the air outlet 30c, and further, an evaporator 36 and a PTC heater 37 arranged side by side in the cabinet width direction on the upstream side of the evaporator fan 35. Also, directly below the evaporator 36, a treatment section 38 is provided to secure the condensed water generated during the cooling operation and evaporate the condensed water with the heat of the condenser 33.

[0027] When using the integrated air conditioner 23 formed in this way, during the cooling operation, the circuit of the PTC heater 37 is in the off state, and the refrigeration cycle is operated by driving the compressor 31. As a result, the refrigerant becomes a high-pressure state by the compressor 31, is sent to the condenser 33, and is condensed and releases heat by the condenser 33. Further, the low-temperature refrigerant passing through the expansion valve is sent to the evaporator 36, absorbs heat (cooling effect) by the evaporator 36, becomes a low-pressure state, and is returned to the compressor 31.

[0028] 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 sent out as cold air from the air outlet 30c. On the other hand, 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 by the inner arc surface 34a of the exhaust duct 34, and is sent out from the exhaust port 30g. Thus, the cooling operation of the integrated air conditioner 23 is performed. At this time, the condensed water generated by the evaporator 36 is secured by the treatment section 38 during natural fall, and then evaporated by the heat of the condenser 33, and is processed inside without draining to the outside.

[0029] During the heating operation, the operation of the refrigeration cycle is stopped, and the circuit of the PTC heater 37 is turned on. As a result, the air taken in from the side air intake 30e is heated by the operation of the evaporator fan 35 also used in the heating operation, and becomes warm air and is sent out from the air outlet 30c. In this way, the heating operation of the integrated air conditioner 23 is performed. Since the PTC heater 37 is a heater that utilizes the PTC characteristic that the resistance value increases as the temperature rises, once a certain temperature is reached, the temperature will not rise any further, preventing overheating and ensuring energy saving and safety.

[0030] The soundproof room 11 formed in this way is optimized in terms of the configuration of the floor material 12b and the arrangement of various air conditioning facilities so as to maximize its air conditioning effect. Specifically, as shown in FIG. 11, the integrated air conditioner 23 is arranged directly below the table 17, with the back surface of the cabinet 30 along the inner wall surface of the housing 12. Furthermore, the left side surface of the cabinet 30 is arranged along the inner wall surface of the housing 12 to which the door 13 is coupled (FIG. 3), that is, in a state of being placed close to the entrance side corner, and anti-tipping measures are taken by fixing brackets (not shown). In addition, the fan 24 provided on the ceiling 12d is arranged so as to be located directly above in relation to the sofa 16. As a result, the cold air or warm air sent into the room from the air outlet 30c forms a gentle upward air flow in combination with the suction force of the operating fan 24 and is discharged to the outside from the ceiling 12d as shown by the arrow A in FIG. 11.

[0031] On the other hand, the floor material 12b of the housing 12 is provided with an opening (not shown) corresponding to the position and size of the exhaust port 30g of the integrated air conditioner 23, and a through air passage 39 is formed through this opening to communicate between the upper and lower surfaces of the upper and lower floor plates 12e and 12f. As a result, the warm air blown out from the exhaust port 30g during the cooling operation is discharged to the floor surface of the place where the soundproof room 11 is installed through the underfloor as shown by the arrow B in FIG. 11.

[0032] Thus, in the first configuration, an opening capable of discharging the warm air blown out from the exhaust port 30g of the integrated air conditioner 23 to the outside is formed in the floor of the soundproof room 11 in which the integrated air conditioner 23 is installed. Therefore, it is possible to separate the exhaust heat of the refrigeration cycle from the cold air without diffusing it into the room, and it is possible to easily realize an air environment with less energy loss. Moreover, due to the underfloor exhaust structure, even when the soundproof room 11 is installed adjacent to the surrounding walls or other soundproof rooms, the exhaust air blown out from under the floor flows without being blocked, and furthermore, it does not give discomfort to nearby people or passersby, so it exhibits an environmentally friendly effect. In addition, a fan 24 is provided on the ceiling 12d, and by its operation, an upward air flow is formed in the soundproof room 11. Therefore, the upward movement of the cold air from the integrated air conditioner 23 is promoted, and it is possible to suck up and air-condition the air in the entire room, and the room temperature can be uniformly adjusted without complicated control.

[0033] Also, the control unit provided in the soundproof room 11 performs control to start the operation of the integrated air conditioner 23 and the fan 24 after receiving the authentication of the reserved user made by the management device. Therefore, it is possible to eliminate the user's annoyance such as the trouble of operating the air conditioning equipment, and the soundproof room 11 can be operated more economically. That is, a structure and an air conditioning system of the soundproof room 11 capable of exhibiting an excellent air conditioning function with a simple configuration are realized, and thus, in various environments where the soundproof room 11 is installed, its comfortable use can be promoted.

[0034] Furthermore, with a set of sofas 16 and a table 17 arranged inside the soundproof room 11, the integrated air conditioner 23 is configured to be located directly below the table 17 and the fan 24 is located directly above the sofa 16. Therefore, the air sent out from the air outlet 30c of the integrated air conditioner 23 forms a gentle upward airflow with an optimal wind speed and airflow spread, realizing a comfortable indoor space where one does not feel the discomfort of the wind directly hitting the skin. Moreover, since the integrated air conditioner 23 is arranged at a position along the inner wall surface of the housing 12 to which the door 13 is coupled on one side surface of the cabinet 30, it can not only respond sensitively to the indoor temperature change caused by the opening and closing operation of the door 13, but also maximize the foot space of the seated user. In addition, by arranging the integrated air conditioner 23 below the table 17, its presence is no longer a concern, and the indoor space design can be beautifully formed.

[0035] Also, since the soundproof room 11 is provided with an integrated automatic fire extinguishing device 26 including a fire extinguishing agent container 27 on the ceiling 12d, the initial fire can be quickly suppressed without relying on human operation. Moreover, the fan 24 provided at the same height position as the automatic fire extinguishing device 26 on the ceiling 12d forms an upward airflow in the room by its operation, promoting the rise of heat from the fire source and enabling quick and reliable heat detection. Consequently, the air conditioning function of the soundproof room 11 can be maximally exerted.

[0036] By the way, in the first configuration, an example is shown in which the exhaust port 30g provided in the integrated air conditioner 23 is provided on the bottom surface of the cabinet 30. However, if there is sufficient space for the installation location of the soundproof room 11, it is not necessarily required to have an underfloor exhaust structure. Also, since there are various installation locations for the soundproof room, in this type of air conditioning system, more efficient operation can be performed according to the required cooling capacity, that is, energy saving is always required. Therefore, below, as a modification example, the configuration and function of an integrated air conditioner integrally mounted on the wall separating the indoor and outdoor spaces of the soundproof room and with the exhaust port exposed to the outdoor side will be described.

[0037] Figs. 12 to 18 show a soundproof room and an air conditioning system for the soundproof room according to the second exemplary embodiment of the present invention. In the following description, the same components as those shown in the first exemplary embodiment are denoted by the same reference numerals, and detailed descriptions thereof are omitted.

[0038] As shown in Figs. 12 to 15, the second integrated air conditioner 51 houses a refrigeration cycle for cooling and a PTC heater as a heating element in the same cabinet. By operating an operation panel 52a provided on the front surface of a rectangular box-shaped cabinet 52, it is possible to select an operation mode of cooling operation or heating operation, input a set temperature, and input an air volume. The cabinet 52 is installed in a soundproof room as a place of use. For example, the front side disposed indoors fits well under a table, and the rear side disposed outdoors has height dimensions and depth dimensions such that an exhaust and intake function can be realized.

[0039] As shown in Fig. 12, on the front surface of the cabinet 52, an air outlet 52b for heating and cooling is provided above the operation panel 52a in the vertical direction, and a front air intake 52c for taking in indoor air is provided below. Further, as shown in Fig. 13, an exhaust port 52d is provided on the right side surface of the cabinet 52, and as shown in Fig. 14, a side air intake 52e is provided on the left side surface of the cabinet 52 at a position facing the exhaust port 52d.

[0040] As shown in Fig. 15, inside the cabinet 52, a partition plate 52f is provided, and thus an indoor heat exchange chamber 53 and an outdoor heat exchange chamber 54 partitioned in the depth direction (the left-right direction in Fig. 15) are formed. As main components, in the indoor heat exchange chamber 53, a compressor 55 is disposed at the lower part, an evaporator 57 and a PTC heater 58 on a mount 56 corresponding to the position of the air outlet 52b, and an evaporator fan 59 located on the back side thereof are arranged side by side. Further, below the evaporator 57, a treatment unit 60 for securing condensed water generated by the cooling operation is provided.

[0041] On one hand, in the outdoor heat exchange chamber 54, on the mounting base 61 and in the space between the side air intake 52e and the exhaust port 52d, a condenser 62 and a condenser fan 63 which is a blower are respectively arranged in a direction considering proper ventilation. Thereby, under the operation of the condenser fan 63, the air taken into the interior from the upstream side air intake 52e passes through the condenser 62 while flowing in the direction along the plate surface of the partition plate 52f (the arrow direction in FIG. 15), and is then sent out to the exterior from the downstream side exhaust port 52d.

[0042] When using the integrated air conditioner 51 formed in this way, during the cooling operation, the circuit of the PTC heater 58 is in the off state, and the refrigeration cycle is operated by driving the compressor 55. Thereby, the refrigerant becomes a high-pressure state by the compressor 55, is sent to the condenser 62, condensed by the condenser 62, and releases heat. Further, the low-temperature refrigerant passing through the expansion valve is sent to the evaporator 57, absorbs heat (cooling effect) by the evaporator 57, becomes a low-pressure state, and is returned to the compressor 55.

[0043] 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, becomes cold air, and is sent out from the air outlet 52b. On the other hand, the heat of the condenser 62 becomes warm air by the operation of the condenser fan 63 and is sent out from the exhaust port 52d. Thus, the cooling operation of the integrated air conditioner 51 is performed. At this time, since the back wall 54a of the outdoor heat exchange chamber 54 and the partition plate 52f are parallel to each other, the air flowing through the space between them is rectified, and as a result, a linear air flow from the side air intake 52e toward the exhaust port 52d is formed. Also, the dew water generated by the evaporator 57 is ensured by the treatment unit 60 during natural fall, then guided to the outdoor heat exchange chamber 54, evaporated by the heat of the condenser 62, and processed inside without draining to the exterior.

[0044] During the heating operation, the operation of the refrigeration cycle is stopped, and the circuit of the PTC heater 58 is turned on. As a result, the air taken in from the front air inlet 52c by the operation of the evaporator fan 59 is heated up and sent out as warm air from the air outlet 52b. In this way, the heating operation of the integrated air conditioner 51 is performed.

[0045] Figs. 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 that of the first exemplary embodiment. However, as shown in Figs. 17 and 18, on the wall of the housing 72, a wall hole 73 corresponding to the outer shape of the cabinet 52 is provided in the wall 72a on the side opposite to the door 13 side (the back side) among the pair of opposed walls.

[0046] The integrated air conditioner 51 has the exhaust port 52d exposed outside the housing 72 and airtightly mounted in the wall hole 73. The air in the outdoor heat exchange chamber 54 can be circulated by the condenser fan 63 along the plate surface of the partition plate 52f, and the warm air blown out from the exhaust port 52d can be discharged along the wall (outer wall surface) 72a of the housing 72. At this time, the cabinet 52 is located at a position where the partition plate 52f corresponds to the wall hole 73, and the indoor heat exchange chamber 53 is arranged on the floor surface along the inner wall surface of the housing 72. In other words, the air outlet 52b is located directly below the table 17. In the state of being mounted on the wall hole 73, anti-drop measures are taken by fixing brackets (not shown).

[0047] As a result, the cold air or warm air sent into the room from the air outlet 52b forms a gentle upward airflow in cooperation with the suction force of the operating fan 24 as shown by the arrow C in Fig. 17 and is discharged to the outside from the ceiling 12d. On the other hand, the warm air blown out from the exhaust port 52d during the cooling operation is discharged along the wall 72a of the housing 72 from the exhaust port 52d while maintaining the airflow velocity in the outdoor heat exchange chamber 54 on the back side of the housing 72 as shown by the arrow D in Fig. 18.

[0048] Thus, in the second configuration, among the walls forming the housing 72 of the soundproof room 71, the integrated air conditioner 51 is mounted in the wall hole 73 provided in the wall 72a on the side opposite to the door 13 side. In this mounted state, since the exhaust port 52d is exposed to the outside of the housing 72, it is possible to separate the exhaust heat of the refrigeration cycle from the cold air without diffusing it into the room, and an air environment with less energy loss can be easily realized. In addition, since the warm air blown out from the exhaust port 52d is formed so as to be discharged in the direction along the wall 72a of the housing 72, even when the soundproof room 71 is installed adjacent to the surrounding walls or other soundproof rooms, the so-called short circuit in which the exhaust gets stagnant and is inhaled into the device again can be suppressed. Therefore, the balance of the refrigeration cycle is maintained, and thereby, it is possible to contribute to the stabilization of the air conditioning capacity. That is, a structure of the soundproof room 71 and an air conditioning system capable of exhibiting an excellent air conditioning function with a simpler configuration are realized, and thus, in various environments where the soundproof room 71 is installed, its comfortable use can be promoted.

[0049] Note that the present invention is not limited to the above-described embodiment. In addition to the facilities related to air conditioning and disaster prevention, the soundproof room can be equipped with various necessary facilities, and the installation location may be a moving body such as a railway vehicle, a bus, a taxi, or an airplane. Further, the shape of the housing is not limited to a rectangular parallelepiped, and may be a cylindrical shape. As long as the advantages of a flexible portable soundproof room are not impaired, it can be formed to have a space capable of accommodating not only one person but also two or more people. In this case, the configuration of the equipment and the air conditioning equipment can be changed within a range that does not give the user a feeling of air flow or discomfort and allows the work and activities in the room to be performed comfortably.

[0050] Furthermore, the fan is provided on the ceiling surface, that is, the same surface where the automatic fire extinguishing device is attached, which not only has a significant air conditioning effect in terms of disaster prevention but also in normal use. However, it is not limited to this, and it can be appropriately changed according to the environment where the soundproof room is installed, such as being provided at the upper part of the side wall surface. In addition, as for the specifications of the integrated air conditioner, various types can be adopted as long as there are exhaust ports on the bottom surface or side surface, and the arrangement of the equipment housed in the cabinet can also be appropriately changed. Also, in the first configuration, the shape of the exhaust duct can be formed not only by, for example, forming the air direction changing part by the inner arc surface, but also by inclined or upright surfaces. Furthermore, as long as the opening provided in the floor material corresponds to the exhaust port of the integrated air conditioner, the size and shape are arbitrary, and considering the air permeability, it may be provided with a large number of dot-shaped or slit-shaped holes having a certain size.

[0051] Also, in the second configuration, as long as the partition plate has a plate surface area necessary for ensuring ventilation in the heat exchange chamber, the shape is not particularly limited, and through holes for installing refrigerant pipelines, electric circuits, etc. can be provided. Furthermore, as long as the air in the outdoor heat exchange chamber can flow in the direction along the plate surface of the partition plate, the exhaust port can be provided not only on the side surface but also, for example, on the upper surface. In this case, compared with a general air conditioner that exhausts from the rear, for example, problems in terms of quality such as inoperability due to the installation conditions such as the wall side in the station where an unspecified number of people pass, or a reduction in the service life due to continuous overloading operation of the compressor do not occur, which is extremely beneficial.
