By the way, the soundproof room 11 is desired to have an air conditioner that can provide a comfortable air environment in a normal use state without giving a thermal discomfort to a user who performs work or activity indoors. In particular, considering that the soundproof room 11 is installed in a public facility such as a station yard, it is expected that the temperature will be higher than the outside air temperature in the summer. Under these circumstances, an integrated air conditioner 23 that prepares the room in a state suitable for cooling or heating is installed on the floor of the soundproof room 11.

5 to 10 show the first soundproof room of the present invention and the first integrated air conditioner 23 applied to the air conditioning system of the soundproof room. The integrated air conditioner 23 has a refrigerating cycle for cooling and a PTC (Positive Temperature Coefficient) heater which is a heating element for heating housed in the same cabinet, and is rectangular as shown in FIG. By operating the operation panel 30a provided on the front surface of the box-shaped cabinet 30, it is possible to select the operation mode of the cooling operation or the heating operation and input the set temperature and the air flow amount. The cabinet 30 has a height dimension that allows it to fit under the table 17 when it is installed in the soundproof chamber 11, and has handles 30b on both the left and right sides on which both hands can be hung during transportation and installation.

On the front surface 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 intake port 30d for taking in indoor air is provided on the lower side. Further, on the left side surface of the cabinet 30, a side intake port 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, while the bottom surface, which is the installation surface of the cabinet 30, has a bottom as shown in FIG. An exhaust port 30g is provided at an end avoiding the lid 30f. 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, thereby ensuring the air permeability of the discharged warm air.

In the cabinet 30, as shown in FIG. 10, the compressor 31 is arranged at the lower part, and the front intake port of the cabinet 30 is placed on a pedestal 32 assembled so as to straddle the compressor 31 by four support columns 32a. A compressor 33 corresponding to the position of 30d and a compressor fan (not shown) are arranged side by side on the rear surface side. Further, a space for exhaust heat is formed on the right side of the gantry 32, and an exhaust duct 34 is provided in this space.

The exhaust duct 34 has a tubular shape having a rectangular cross section extending in the vertical direction along the inner surface of the cabinet 30, and the upper end portion takes in the horizontal air flow (warm air) from the condenser fan to flow vertically downward. It is formed to have an arc inner side surface 34a to be changed, and a lower end portion is connected to an exhaust port 30g. In this way, the compressor 31, the condenser 33, the condenser fan, and the exhaust duct 34 are mainly arranged in the lower half of the cabinet 30.

In the upper part of the cabinet 30, there is a control circuit for controlling the operating state of heating and cooling, an evaporator fan 35 provided corresponding to the positions of the side intake ports 30e and the air outlet 30c, and further, an evaporator fan 35. The evaporator 36 and the PTC heater 37, which are on the upstream side of the cabinet and are arranged side by side in the width direction of the cabinet, are arranged. Further, directly below the evaporator 36, a treatment unit 38 for securing the condensed water generated by the cooling operation and evaporating the condensed water with the heat of the condenser 33 is provided.

When the integrated air conditioner 23 formed in this way is used, the circuit of the PTC heater 37 is in the off state during the cooling operation, and the refrigeration cycle is operated by driving the compressor 31. As a result, the refrigerant is brought into a high pressure state by the compressor 31, is sent to the condenser 33, is condensed by the condenser 33, and is dissipated. Further, the low-temperature refrigerant that has passed through the expansion valve is sent to the evaporator 36, is endothermic (cooling effect) by the evaporator 36, becomes a low-pressure state, and is returned to the compressor 31.

Here, the air taken in from the side intake port 30e by the operation of the evaporator fan 35 is cooled by the evaporator 36, becomes cold air, and is sent out 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, flows into the upper part of the exhaust duct 34, and flows vertically downward by the arc inner side surface 34a of the exhaust duct 34, so that the exhaust port 30 g. Is sent from. 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 secured by the treatment unit 38 during free fall, and then evaporates by the heat of the condenser 33, and is treated internally without being drained to the outside.

During the heating operation, the refrigeration cycle operation is stopped and the circuit of the PTC heater 37 is turned on. As a result, the air taken in from the side intake port 30e is raised by the operation of the evaporator fan 35, which is 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, when the temperature reaches a certain level, the temperature does not rise any more to prevent overheating, resulting in energy saving and safety. Is secured.

The soundproof chamber 11 formed in this way is optimized for the configuration of the floor material 12b and the arrangement of various air conditioning equipment so that the air conditioning effect can be maximized.

A fall prevention measure is provided by a fixing bracket (not shown) with the surface aligned with the inner wall surface of the cabinet 12 to which the door 13 is connected (FIG. 3), that is, arranged so as to be close to the entrance / exit side corner. Has been made. In addition to this, 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 hot air sent out from the air outlet 30c into the room gently forms an updraft in combination with the suction force of the operating fan 24, as shown by the arrow A in FIG. It is released to the outside from 12d.

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 the upper and lower floor plates 12e and 12f are provided by this opening. A passing air passage 39 communicating between the upper surface and the lower surface of the air conditioner 39 is formed. As a result, the warm air blown out from the exhaust port 30 g during the cooling operation passes under the floor and is discharged to the floor surface of the place where the soundproof chamber 11 is installed, as shown by the arrow B in FIG.

As described above, in the first configuration, the floor of the soundproof room 11 in which the integrated air conditioner 23 is installed has an opening capable of discharging warm air blown from the exhaust port 30 g of the integrated air conditioner 23 to the outside. Since it is formed, it is possible to separate the exhaust heat of the refrigeration cycle from the cold air without diffusing it indoors, and it is possible to easily realize an air environment with little energy loss. Moreover, due to the underfloor exhaust structure, even if the soundproof room 11 is installed next to the surrounding wall or other soundproof room, the exhaust blown out from under the floor flows without clogging, and further, nearby people and traffic Since it does not cause discomfort to people, it has an environmentally friendly effect. In addition to this, a fan 24 is provided on the ceiling 12d, and its operation forms an updraft in the soundproof chamber 11, so that the rise of cold air from the integrated air conditioner 23 is promoted and the air in the entire room is sucked up. It is possible to air-condition the room, and the room temperature can be adjusted uniformly without complicated control.

Further, since the control unit provided in the soundproof room 11 controls to start the operation of the integrated air conditioner 23 and the fan 24 by receiving the authentication of the reserved user performed by the management device, it is troublesome to operate the air conditioning equipment. The troublesomeness of the user can be eliminated, and the soundproof room 11 can be operated more economically. That is, the structure and air-conditioning system of the soundproof room 11 capable of exhibiting an excellent air-conditioning function with a simple configuration can be realized, and the comfortable use thereof can be promoted in various environments in which the soundproof room 11 is installed. Become.

Further, with a set of sofas 16 and a table 17 arranged in the soundproof room 11, the integrated air conditioner 23 is located directly below the table 17 and the fan 24 is located directly above the sofa 16. Therefore, the wind sent from the air outlet 30c of the integrated air conditioner 23 gently forms an updraft with the optimum wind speed and spread of the airflow, and the comfortable room where the wind directly hits the skin does not make you feel uncomfortable. Space can be realized. Moreover, since the integrated air conditioner 23 arranges one side surface of the cabinet 30 along the inner wall surface of the housing 12 to which the door 13 is connected, the temperature in the room changes due to the opening / closing operation of the door 13. Not only can it react sensitively, but it can also maximize the foot space of the seated user. Moreover, by arranging the integrated air conditioner 23 under the table 17, it is possible to beautifully form the interior space design without worrying about its existence.

Further, 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 depending on human operation. Moreover, a fan 24 provided on the ceiling 12d at the same height as the automatic fire extinguishing device 26 forms an updraft in the room by its operation, so that the heat from the fire source is promoted to rise quickly and surely. Detection is possible, and the air conditioning function of the soundproof room 11 can be maximized.

By the way, in the first configuration, an example in which the exhaust port 30 g provided in the integrated air conditioner 23 is provided on the bottom surface of the cabinet 30 is shown, but if a sufficient space can be secured for the installation location of the soundproof room 11. , It is not always necessary to have an underfloor exhaust structure. In addition, since the soundproof rooms are installed in various places, it is always required that this type of air conditioning system can be operated more efficiently according to the required cooling capacity, that is, energy saving. Has been done. Therefore, in the following, as a modification, the configuration and its function of an integrated air conditioner that is integrally mounted on the wall separating the indoor and outdoor areas of the soundproof room and can expose the exhaust port to the outdoor side will be described.

When the integrated air conditioner 51 formed in this way is used, the circuit of the PTC heater 58 is in the off state during the cooling operation, and the refrigeration cycle is operated by driving the compressor 55. As a result, the refrigerant is brought into a high pressure state by the compressor 55, sent to the condenser 62, condensed by the condenser 62, and dissipated. Further, the low-temperature refrigerant that has passed through the expansion valve is sent to the evaporator 57, is endothermic (cooling effect) by the evaporator 57, becomes a low-pressure state, and is returned to the compressor 55.

Here, the air taken in from the front intake port 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. In this way, 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, the side intake port 52e to the exhaust port A linear airflow toward 52d is formed. Further, the condensed water generated by the evaporator 57 is secured by the treatment unit 60 during free fall, and then guided to the outdoor heat exchange chamber 54 to evaporate with the heat of the condenser 62 and drained to the outside. No processing is done internally.

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

16 to 18 show a soundproof room to which the integrated air conditioner 51 is applied. The second soundproof chamber 71 basically has the same configuration and function as that of the first embodiment, but faces the wall of the housing 72 as shown in FIGS. 17 and 18. Of the pair of arranged walls, a wall hole 73 corresponding to the outer shape of the cabinet 52 is provided on the wall 72a on the side (back side) opposite to the door 13 side.

In the integrated air conditioner 51, the air in the outdoor heat exchange chamber 54 is separated by the condenser fan 63 with the exhaust port 52d exposed to the outside of the housing 72 and airtightly mounted in the wall hole 73. The warm air blown out from the exhaust port 52d can be discharged in the direction along the wall (outer wall surface) 72a of the housing 72. At this time, in the cabinet 52, the partition plate 52f is located at a position corresponding 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. With the 52b positioned directly below the table 17 and mounted in the wall hole 73, a fixing bracket (not shown) is used to prevent the table from falling off.

As a result, the cold air or hot air sent into the room from the air outlet 52b gently forms an updraft in combination with the suction force of the operating fan 24, as shown by the arrow C in FIG. 17, and the ceiling. It is released to the outside from 12d. On the other hand, as shown by the arrow D in FIG. 18, the warm air blown out from the exhaust port 52d during the cooling operation keeps the air flow velocity in the outdoor heat exchange chamber 54 on the back side of the housing 72 and is exhausted. It is discharged from 52d along the wall 72a of the housing 72.

As described above, in the second configuration, 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 among the walls forming the housing 72 of the soundproof chamber 71. 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 the air environment with less energy loss is simplified. Can be realized. In addition to this, 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, the soundproof chamber 71 is installed next to the surrounding wall and other soundproof chambers. Even in the case of this, it is possible to suppress the occurrence of a so-called short circuit in which the exhaust is stagnant and is sucked into the device again, so that the balance of the refrigeration cycle is maintained, which contributes to the stabilization of the air conditioning capacity. Can be done. That is, the structure and air-conditioning system of the soundproof room 71 capable of exhibiting an excellent air-conditioning function with a simpler configuration are realized, and the comfortable use thereof can be promoted in various environments in which the soundproof room 71 is installed. It becomes.

The present invention is not limited to the above embodiment, and the soundproof room can be provided with various necessary equipment in addition to equipment related to air conditioning and disaster prevention, and the installation location is a railroad vehicle, a bus, or a taxi. Alternatively, it may be a moving body such as an airplane. Further, the shape of the housing is not limited to a rectangular parallelepiped, but may be a cylindrical shape, and can accommodate not only one person but also two or more people as long as the advantages of the flexible portable soundproof room are not impaired. It can be formed with a space. In this case, the configuration of the equipment and the air-conditioning equipment can be changed within a range in which the user can comfortably perform work and activities in the room without giving the user a feeling of airflow or discomfort.

Furthermore, by installing the fan on the ceiling surface, that is, on the same surface as the surface on which the automatic fire extinguishing device is attached, not only for disaster prevention but also for normal use, a remarkable air conditioning effect is exhibited, but the fan is not limited to this. , It can be changed as appropriate, such as by providing it on the upper part of the side wall surface according to the environment in which the soundproof room is installed. In addition, various specifications of the integrated air conditioner can be adopted as long as the bottom and side surfaces are provided with exhaust ports, and the arrangement of the equipment housed in the cabinet can be changed as appropriate. Further, in the first configuration, the shape of the exhaust duct may be formed not only by the inner surface of the arc, but also by an inclined or upright surface, for example. Further, if the opening provided in the floor material is provided corresponding to the exhaust port of the integrated air conditioner, the size and shape are arbitrary, and the dots have a certain size in consideration of air permeability. A large number of shaped or slit-shaped holes may be provided.

Further, in the second configuration, the shape is not particularly limited as long as the partition plate has a plate surface having a size necessary for ensuring ventilation in the heat exchange chamber, and a refrigerant pipe, an electric circuit, or the like is installed. A through hole can be provided. Further, if the air in the outdoor heat exchange chamber can be circulated 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 on, for example, the upper surface. In this case, if compared with a general air conditioner that exhausts air from the rear surface, for example, operation is not possible due to the conditions of the installation location such as near the wall of the station yard where an unspecified number of people pass, or the compressor is continuously overloaded. It is extremely beneficial because it does not cause quality problems such as shortened life due to the above.
