DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, embodiments will be described with reference to the drawings. Embodiment 1 Fig. 1 is a schematic diagram showing an elevator according to embodiment 1. In the figure, a machine room 2 is provided above a hoistway 1. In the machine room 2, a hoist 3, a deflector sheave 4, and an elevator control device 5 are installed.

[0010] The hoist 3 has a drive sheave 6, a hoist motor (not shown), and a hoist brake (not shown). The hoist motor rotates the drive sheave 6. The hoist brake keeps the drive sheave 6 stationary. The hoist brake also brakes the rotation of the drive sheave 6.

[0011] A suspension body 7 is wound around the drive sheave 6 and the deflector sheave 4. A plurality of ropes or a plurality of belts are used as the suspension body 7. A cage 8 serving as a moving body is connected to a first end of the suspension body 7. A counterweight 9 is connected to a second end of the suspension body 7.

[0012] The car 8 and counterweight 9 are suspended by a suspension body 7, and move vertically in the hoistway 1 by rotating the drive sheave 6. The elevator control device 5 controls the operation of the car 8 by controlling the hoisting machine 3.

[0013] A pair of car guide rails (not shown) and a pair of counterweight guide rails (not shown) are installed in the hoistway 1. The pair of car guide rails guide the ascent and descent of the car 8. The pair of counterweight guide rails guide the ascent and descent of the counterweight 9.

[0014] The car 8 has a car frame 10 and a car chamber 11. The suspension body 7 is connected to the car frame 10. The car chamber 11 is supported by the car frame 10. A car door 12 is provided at the front of the car chamber 11.

[0015] Each of the landings on the multiple floors is provided with a landing door 13. Each landing door 13 opens and closes in conjunction with the car door 12 when the car 8 lands on the floor.

[0016] An adsorbent-using container 21 is attached to the lower part of the cage 8. The adsorbent-using container 21 is disposed below the cage chamber 11. That is, the adsorbent-using container 21 is disposed outside the cage chamber 11.

[0017] Fig. 2 is a side view showing a main part of the elevator in Fig. 1. In the first embodiment, when the counterweight 9 is located at the same height as the car 8, it faces the back surface of the car room 11. That is, the lifting area of ​​the counterweight 9 is located behind the lifting area of ​​the car 8 when viewed from the landing.

[0018] The car frame 10 has an upper beam 10a, a pair of vertical columns 10b, and a lower beam 10c. The upper beam 10a is horizontally fixed between the upper ends of the pair of vertical columns 10b. A first end of the suspension body 7 is connected to the upper beam 10a.

[0019] The lower beam 10c is fixed horizontally between a pair of vertical columns 10b below the upper beam 10a. The car chamber 11 is supported on the lower beam 10c below the upper beam 10a. The car chamber 11 is also located between the pair of vertical columns 10b.

[0020] Although omitted in Fig. 1, the car chamber 11 is provided with a car threshold 14 and an apron 15. The car threshold 14 is provided at the lower front surface of the car chamber 11. In addition, the car threshold 14 guides the lower end of the car door 12 when the car door 12 is opened or closed.

[0021] The apron 15 is fixed to the car sill 14. In addition, the apron 15 protrudes downward from the car sill 14.

[0022] The adsorbent-using container 21 is supported by the lower beam 10c via a pair of support arms 16. Only one of the pair of support arms 16 is shown in Fig. 2. Note that Fig. 2 shows a cross section of the adsorbent-using container 21.

[0023] The adsorbent-using container 21 is disposed below the lower beam 10c with a gap between it and the lower beam 10c. This ensures a ventilation path between the lower part of the cage 11 and the adsorbent-using container 21.

[0024] The adsorbent use container 21 has a use container body 21a and a flat use container lid 21b. The use container body 21a has air permeability. When the cage 8 moves downward, an upward air flow is generated in the use container body 21a.

[0025] The carbon dioxide adsorbent 31 is accommodated in the adsorbent-using container 21. The carbon dioxide adsorbent 31 has air permeability. The carbon dioxide adsorbent 31 includes a plurality of granular carbon dioxide adsorbents. The outer shape of each carbon dioxide adsorbent is, for example, pellet-like or bead-like.

[0026] The configuration of the carbon dioxide adsorbent 31 is not limited to a configuration including a plurality of granular carbon dioxide adsorbents. For example, the carbon dioxide adsorbent 31 may be made of a honeycomb-shaped carbon dioxide adsorbent material.

[0027] As the car 8 moves, the air in the elevator 1 is passed through the carbon dioxide adsorbent 31. That is, as the car 8 moves downward, air enters the adsorbent-use container 21 from the bottom surface of the container body 21a. The air that has entered the adsorbent-use container 21 passes through the carbon dioxide adsorbent 31 and is discharged to the outside of the adsorbent-use container 21 from the top surface of the container body 21a.

[0028] Carbon dioxide in the air is adsorbed by the carbon dioxide adsorbent 31 as it passes through the adsorbent-using vessel 21 .

[0029] Although not shown in Fig. 1, an adsorbent recovery container 22 and an adsorbent replenishment container 23 are provided on a wall 1a facing the rear surface of the car chamber 11 in the elevator 1. The adsorbent recovery container 22 and the adsorbent replenishment container 23 are arranged at a distance from each other in the vertical direction.

[0030] The adsorbent use container 21, the adsorbent recovery container 22, and the adsorbent replenishment container 23 are arranged at the same position in the width direction of the car 8. The width direction of the car 8 is parallel to the opening and closing direction of the car door 12, and is perpendicular to the paper surface of FIG.

[0031] The adsorbent collection container 22 has a cylindrical collection container body 22a and a flat collection container lid 22b. An upper collection container opening is provided at the upper end of the collection container body 22a. A lower collection container opening is provided at the lower end of the collection container body 22a.

[0032] The collection container lid 22b is provided on the lower part of the collection container body 22a and opens and closes the lower opening of the collection container.

[0033] The adsorbent replenishment container 23 has a cylindrical replenishment container body 23a and a flat replenishment container lid 23b. An upper replenishment container opening is provided at the upper end of the replenishment container body 23a. A lower replenishment container opening is provided at the lower end of the replenishment container body 23a.

[0034] The refill container lid 23b is provided on the lower part of the refill container body 23a, and opens and closes the lower opening of the refill container.

[0035] A use container opening is provided at one end of the adsorbent use container 21 facing the wall 1a on which the adsorbent recovery container 22 and the adsorbent replenishment container 23 are provided. The use container lid 21b opens and closes the use container opening.

[0036] At least one of the adsorbent-used container 21, the car 8, and the elevator 1 is provided with an exchanging mechanism 24. The exchanging mechanism 24 in the first embodiment has a container rotation device 25 and a lid rotation device 26. A motor is used as each of the container rotation device 25 and the lid rotation device 26.

[0037] The container rotation device 25 is provided on one of the pair of support arms 16. That is, the container rotation device 25 is provided on the cage 8 via the support arm 16. The container rotation device 25 rotates the adsorbent-containing container 21 relative to the cage 8 between a horizontal state and an inclined state, about an axis parallel to the width direction of the cage 8.

[0038] The horizontal state is a state in which the adsorbent-using container 21 is horizontal, as shown in Fig. 2. The inclined state is a state in which the adsorbent-using container 21 is inclined with respect to the horizontal plane, as shown in Figs.

[0039] The lid rotation device 26 opens and closes the container opening by rotating the container lid 21b relative to the container body 21a.

[0040] When the cage 8 stops at a position corresponding to the adsorbent recovery container 22, the replacement mechanism 24 connects the adsorbent use container 21 to the adsorbent recovery container 22 and moves the carbon dioxide adsorbent 31 in the adsorbent use container 21 into the adsorbent recovery container 22.

[0041] In addition, when the cage 8 stops at a position corresponding to the adsorbent replenishment container 23, the replacement mechanism 24 connects the adsorbent use container 21 to the adsorbent replenishment container 23 and moves the carbon dioxide adsorbent 31 in the adsorbent replenishment container 23 into the adsorbent use container 21.

[0042] The carbon dioxide capture system 30 of the first embodiment has an adsorbent use container 21, an adsorbent capture container 22, an adsorbent replenishment container 23, and an exchanging mechanism 24. The carbon dioxide capture system 30 is controlled by an elevator control device 5. That is, the container rotation device 25 and the lid rotation device 26 are controlled by the elevator control device 5.

[0043] Fig. 3 is a side view showing a state in which the carbon dioxide adsorbent 31 has been moved from the adsorbent use container 21 to the adsorbent recovery container 22 in Fig. 2. Note that Fig. 3 shows cross sections of the adsorbent use container 21 and the adsorbent recovery container 22.

[0044] When the carbon dioxide adsorbent 31 that has adsorbed carbon dioxide is to be recovered in the adsorbent recovery container 22, the cage 8 is stopped at a position corresponding to the adsorbent recovery container 22. In this example, the position corresponding to the adsorbent recovery container 22 is a position where the adsorbent use container 21 is located above the adsorbent recovery container 22 and is a position where the adsorbent use container 21 can be connected to the adsorbent recovery container 22.

[0045] Thereafter, the adsorbent-used container 21 is tilted so that the opening of the used container faces downward. Then, the used container lid 21b is rotated so that the tip of the used container lid 21b abuts against the edge of the upper opening of the collection container.

[0046] As a result, the carbon dioxide adsorbent 31 in the adsorbent use container 21 moves into the adsorbent recovery container 22 by its own weight. That is, the replacing mechanism 24 tilts the adsorbent use container 21 with respect to the horizontal plane, thereby moving the carbon dioxide adsorbent 31 in the adsorbent use container 21 into the adsorbent recovery container 22 by the weight of the carbon dioxide adsorbent 31.

[0047] Fig. 4 is a side view showing a state in which the carbon dioxide adsorbent 31 has been moved from the adsorbent replenishment container 23 to the adsorbent using container 21 in Fig. 2. Note that Fig. 4 shows cross sections of the adsorbent using container 21 and the adsorbent replenishment container 23.

[0048] When the carbon dioxide adsorbent 31 before carbon dioxide adsorption is to be replenished into an empty adsorbent use container 21, the cage 8 is stopped at a position corresponding to the adsorbent replenishment container 23. In this example, the position corresponding to the adsorbent use container 23 is a position where the adsorbent use container 21 is located below the adsorbent replenishment container 23 and is a position where the adsorbent use container 21 can be connected to the adsorbent replenishment container 23.

[0049] After that, the adsorbent use container 21 is tilted so that the use container opening is at the top. Then, the use container lid 21b is rotated to open the use container opening. At this time, the use container lid 21b comes into contact with the refill container lid 23b, and the rotation of the use container lid 21b also rotates the refill container lid 23b in the opening direction.

[0050] As a result, the carbon dioxide adsorbent 31 in the adsorbent replenishment container 23 moves under its own weight into the adsorbent using container 21. That is, the replacement mechanism 24 tilts the adsorbent using container 21 with respect to the horizontal plane and causes the refilling container lid 23b to perform an opening operation, thereby moving the carbon dioxide adsorbent 31 in the adsorbent replenishment container 23 into the adsorbent using container 21 under its own weight.

[0051] When the carbon dioxide adsorbent 31 before carbon dioxide adsorption is replenished into the adsorbent-use container 21, the use container opening is closed by the use container lid 21b, and the adsorbent-use container 21 is returned to the horizontal position.

[0052] 5 is a block diagram showing the elevator carbon dioxide capture system according to Embodiment 1. The carbon dioxide capture system has an elevator control device 5, a carbon dioxide capture device 30, and a monitoring device 40.

[0053] The monitoring device 40 has a replacement determination unit 41, a replacement command unit 42, and a notification unit 43 as functional blocks.

[0054] The replacement determination unit 41 determines whether or not it is necessary to replace the carbon dioxide adsorbent 31. For example, the replacement determination unit 41 determines that it is necessary to replace the carbon dioxide adsorbent 31 based on a preset replacement period.

[0055] The replacement determination unit 41 may determine whether replacement is necessary based on operation information of the car 8. In this case, the replacement determination unit 41 acquires operation information of the car 8 from the elevator control device 5. Examples of the operation information of the car 8 include travel time information and travel distance information. The travel time information is information on the total travel time of the car 8. The travel distance information is information on the total travel distance of the car 8.

[0056] A travel time threshold or a travel distance threshold is set in the monitoring device 40. Then, the replacement determination unit 41 determines that replacement of the carbon dioxide adsorbent 31 is necessary when the total travel time of the car 8 reaches the travel time threshold or when the total travel distance of the car 8 reaches the travel distance threshold.

[0057] The weight of the carbon dioxide adsorbent 31 increases as it adsorbs carbon dioxide and moisture in the air. As carbon dioxide and moisture are adsorbed, the carbon dioxide adsorption capacity of the carbon dioxide adsorbent 31 gradually decreases. For this reason, the replacement determination unit 41 may determine whether or not replacement is necessary based on the weight of the carbon dioxide adsorbent 31 in the adsorbent-using container 21.

[0058] In this case, a weight detector (not shown) is provided in the adsorbent-using container 21. The weight detector detects the weight of the carbon dioxide adsorbent 31. The monitoring device 40 acquires information from the weight detector directly or via the elevator control device 5.

[0059] A weight threshold is set in the monitoring device 40. Then, the replacement determination unit 41 determines that replacement of the carbon dioxide adsorbent 31 is necessary when the weight of the carbon dioxide adsorbent 31 reaches the weight threshold.

[0060] The replacement determination unit 41 may also determine whether or not replacement of the carbon dioxide adsorbent 31 is necessary based on the time that has elapsed since the carbon dioxide adsorbent 31 was last replaced.

[0061] In this case, an elapsed time threshold is set in the monitoring device 40. Then, the replacement determination unit 41 determines that replacement of the carbon dioxide adsorbent 31 is necessary when the time elapsed since the previous replacement reaches the elapsed time threshold.

[0062] The replacement determination unit 41 may determine whether or not replacement of the carbon dioxide adsorbent 31 is necessary based on the carbon dioxide concentration in the air that has passed through the adsorbent-using container 21 .

[0063] In this case, a concentration sensor (not shown) is provided in the adsorbent use container 21. The concentration sensor detects the concentration of carbon dioxide.

[0064] A concentration threshold is set in the monitoring device 40. Then, the replacement determination unit 41 determines that replacement of the carbon dioxide adsorbent 31 is necessary when the carbon dioxide concentration in the air that has passed through the adsorbent-using container 21 becomes equal to or higher than the concentration threshold.

[0065] The replacement command unit 42 transmits a replacement command signal to the elevator control device 5 when the replacement determination unit 41 determines that the carbon dioxide adsorbent 31 needs to be replaced.

[0066] When the elevator control device 5 receives a replacement command signal from the monitoring device 40, it moves the carbon dioxide adsorbent 31 in the adsorbent use container 21 to the adsorbent recovery container 22 at a timing when no call registration is occurring. Then, it moves the carbon dioxide adsorbent 31 in the adsorbent replenishment container 23 into the adsorbent use container 21.

[0067] When a replacement command signal is transmitted from the replacement command unit 42 to the elevator control device 5, the notification unit 43 transmits a notification signal to the information center 60 via the communication network 50. The notification signal is a signal for notifying that replacement of the carbon dioxide adsorbent 31 has been performed.

[0068] When the information center 60 receives the notification signal, it notifies the maintenance person of the elevator in which the carbon dioxide adsorbent 31 has been replaced that the carbon dioxide adsorbent 31 has been replaced.

[0069] Thereafter, a maintenance person who has been contacted by information center 60 recovers the carbon dioxide adsorbent 31 from the adsorbent recovery container 22 and replenishes the carbon dioxide adsorbent 31 into the adsorbent replenishment container 23. These operations can be performed, for example, by the maintenance person riding on the car 8.

[0070] The carbon dioxide adsorbent 31 after adsorption of carbon dioxide is heated by a heating device (not shown), whereby carbon dioxide is separated from the carbon dioxide adsorbent 31 and the carbon dioxide adsorbent 31 is returned to the state before the carbon dioxide adsorption.

[0071] Fig. 6 is a flow chart showing replacement determination processing by the monitoring device 40 of Fig. 5. The monitoring device 40 repeatedly executes the replacement determination processing shown in Fig. 6 at a set cycle.

[0072] When the replacement determination process is started, in step S101, the monitoring device 40 determines whether or not it is necessary to replace the carbon dioxide adsorbent 31. If it is not necessary to replace the carbon dioxide adsorbent 31, the monitoring device 40 ends the process for that cycle.

[0073] If replacement of the carbon dioxide adsorbent 31 is necessary, the monitoring device 40 transmits a replacement command signal to the elevator control device 5 in step S102. Thereafter, the monitoring device 40 transmits a notification signal to the information center 60 in step S103, and ends the processing for that round.

[0074] In such an elevator and its carbon dioxide capture device 30, the adsorbent container 21 is provided in the car 8. A carbon dioxide adsorbent 31 is housed in the adsorbent container 21. When the car 8 moves with the carbon dioxide adsorbent 31 housed in the adsorbent container 21, the air in the elevator shaft 1 is passed through the carbon dioxide adsorbent 31, and the carbon dioxide in the air is adsorbed by the carbon dioxide adsorbent 31.

[0075] Therefore, regardless of the vertical length of the hoistway 1, the carbon dioxide within the hoistway 1 can be efficiently collected by utilizing the driving force of the hoistway 3.

[0076] In addition, an adsorbent recovery container 22 is installed in the elevator 1. Then, the replacement mechanism 24 connects the adsorbent use container 21 to the adsorbent recovery container 22, and moves the carbon dioxide adsorbent 31 in the adsorbent use container 21 into the adsorbent recovery container 22.

[0077] Therefore, regardless of the position of the adsorbent-using container 21 in the cage 8, the carbon dioxide adsorbent 31 can be easily collected, and the labor required for maintenance can be reduced.

[0078] Furthermore, the replacing mechanism 24 tilts the adsorbent use container 21 with respect to the horizontal plane, thereby moving the carbon dioxide adsorbent 31 in the adsorbent use container 21 into the adsorbent recovery container 22 by the weight of the carbon dioxide adsorbent 31. Therefore, with a simple configuration, it is possible to easily recover the carbon dioxide adsorbent 31 containing only the carbon dioxide adsorbent.

[0079] In addition, an adsorbent replenishment container 23 is installed in the elevator 1. Then, the replacement mechanism 24 connects the adsorbent use container 21 to the adsorbent replenishment container 23, and moves the carbon dioxide adsorbent 31 in the adsorbent replenishment container 23 into the adsorbent use container 21.

[0080] Therefore, regardless of the position of the adsorbent-using container 21 in the cage 8, the carbon dioxide adsorbent 31 before carbon dioxide adsorption can be easily replenished, and the labor required for maintenance can be reduced. This improves the degree of freedom in the installation position of the adsorbent-using container 21 in the cage 8.

[0081] In addition, the carbon dioxide capture efficiency can be maintained for a longer period of time, and the intervals between maintenance work can be extended.

[0082] Furthermore, the replacing mechanism 24 tilts the adsorbent using container 21 with respect to the horizontal plane and opens the refilling container lid 23b, thereby moving the carbon dioxide adsorbent 31 in the adsorbent refilling container 23 into the adsorbent using container 21 by the weight of the carbon dioxide adsorbent 31. Therefore, with a simple configuration, it is possible to easily replenish the carbon dioxide adsorbent 31 before carbon dioxide adsorption.

[0083] Moreover, in the monitoring device 40 of the carbon dioxide capture system according to the first embodiment, the replacement determination unit 41 determines whether or not it is necessary to replace the carbon dioxide adsorbent 31. Then, when the replacement determination unit 41 determines that it is necessary to replace the carbon dioxide adsorbent 31, a replacement command signal is transmitted to the elevator control device 5.

[0084] Therefore, by replacing the carbon dioxide adsorbent 31 at more appropriate timing, the adsorption performance of the carbon dioxide adsorbent 31 is maintained, and carbon dioxide can be efficiently captured for a longer period of time.

[0085] Furthermore, when a replacement command signal is transmitted from replacement command unit 42 to elevator control device 5, a notification signal is transmitted from notification unit 43 to information center 60. This makes it possible to collect carbon dioxide adsorbents 31 that have already adsorbed carbon dioxide, or replenish carbon dioxide adsorbents 31 before adsorbing carbon dioxide, at a more appropriate timing. This makes it possible to efficiently capture carbon dioxide for a longer period of time, and also reduces the effort required for maintenance work.

[0086] The adsorbent recovery container 22 and the adsorbent replenishment container 23 may be installed on a wall facing the side surface of the car chamber 11 in the elevator 1, avoiding the car guide rail.

[0087] Embodiment 2 Next, Fig. 7 is a side view showing a main part of an elevator according to embodiment 2. Although omitted in Fig. 1, a landing threshold 17 is provided at each of the landings on multiple floors. Each landing threshold 17 guides the lower end of the landing door 13 when the landing door 13 is opened or closed. A fasher plate 18 is provided at the bottom of each landing threshold 17.

[0088] The adsorbent recovery container 22 and the adsorbent replenishment container 23 are provided on different Fescher plates 18. Furthermore, each of the adsorbent recovery container 22 and the adsorbent replenishment container 23 also serves as a part or the whole of the Fescher plate 18. Furthermore, each of the adsorbent recovery container 22 and the adsorbent replenishment container 23 may be a container attached to the flat Fescher plate 18.

[0089] The adsorbent recovery container 22 and the adsorbent replenishment container 23 are each located in a range between the wall 1b of the hoistway 1 on the landing side and the end face of the landing threshold 17 on the hoistway 1 side, in the front-to-rear direction of the car 8. The front-to-rear direction of the car 8 is perpendicular to the width direction of the car 8 and is horizontal.

[0090] A collection container door 27 is provided on the landing wall of the floor on which the adsorbent collection container 22 is installed. The collection container door 27 opens and closes a collection container opening (not shown). The carbon dioxide adsorbent 31 in the adsorbent collection container 22 can be removed from the landing through the collection container opening.

[0091] In this case, the carbon dioxide adsorbent 31 is removed from the adsorbent recovery vessel 22 while the adsorbent recovery vessel 22 remains installed in the elevator 1. Alternatively, the carbon dioxide adsorbent 31 may be removed from the adsorbent recovery vessel 22 while the adsorbent recovery vessel 22 is removed to a landing.

[0092] A refill container door 28 is provided on the landing wall of the floor on which the adsorbent refill container 23 is installed. The refill container door 28 opens and closes a refill container opening (not shown). The adsorbent refill container 23 can be refilled with carbon dioxide adsorbent 31 from the landing through the refill container opening.

[0093] In this case, the carbon dioxide adsorbent 31 is replenished into the adsorbent replenishment container 23 while the adsorbent replenishment container 23 remains installed in the elevator 1. Alternatively, the carbon dioxide adsorbent 31 may be replenished into the adsorbent replenishment container 23 while the adsorbent replenishment container 23 is taken out to the landing.

[0094] In this way, in the second embodiment, the carbon dioxide adsorbent 31 can be removed from the adsorbent recovery container 22 from the landing. In addition, the carbon dioxide adsorbent 31 can be replenished into the adsorbent replenishment container 23 from the landing.

[0095] Other configurations in the second embodiment are similar to those in the first embodiment.

[0096] With this configuration, it is possible to obtain the same effects as in embodiment 1. In addition, it is possible to further reduce the maintenance work.

[0097] Furthermore, the carbon dioxide adsorbent 31 can be removed from the adsorbent recovery container 22 and the carbon dioxide adsorbent 31 can be replenished into the adsorbent replenishment container 23 without stopping the operation of the car 8. This improves the degree of freedom in the timing of the replacement work compared to when the replacement work of the carbon dioxide adsorbent 31 is performed on the car 8. This makes it possible to shorten the time during which the carbon dioxide adsorbent 31 that has already adsorbed carbon dioxide remains in the adsorbent recovery container 22 and the time during which the adsorbent replenishment container 23 is empty, thereby further improving the efficiency of carbon dioxide recovery in the elevator 1.

[0098] In addition, the adsorbent recovery container 22 and the adsorbent replenishment container 23 are each provided on the Fescher plate 18. Therefore, the space in the hoistway 1 can be effectively utilized to place the adsorbent recovery container 22 and the adsorbent replenishment container 23 in the hoistway 1.

[0099] The method for recovering the carbon dioxide adsorbent 31 that has already adsorbed carbon dioxide may be a method of exchanging the adsorbent recovery vessel 22 filled with the carbon dioxide adsorbent 31 that has already adsorbed carbon dioxide for an empty adsorbent recovery vessel 22.

[0100] In addition, a method for replenishing the carbon dioxide adsorbent 31 before carbon dioxide adsorption may be a method of replacing an empty adsorbent replenishing container 23 with an adsorbent replenishing container 23 filled with the carbon dioxide adsorbent 31 before carbon dioxide adsorption.

[0101] Furthermore, the adsorbent recovery container 22 and the adsorbent replenishment container 23 may be a common container. That is, a recovery and replenishment container serving as both the adsorbent recovery container 22 and the adsorbent replenishment container 23 may be used. In this case, the carbon dioxide adsorbent 31 after carbon dioxide adsorption is removed from the recovery and replenishment container, and the carbon dioxide adsorbent 31 before carbon dioxide adsorption is replenished to the recovery and replenishment container. Furthermore, the carbon dioxide adsorbent 31 before carbon dioxide adsorption is replenished from the recovery and replenishment container to the adsorbent use container 21, and the carbon dioxide adsorbent 31 after carbon dioxide adsorption is recovered from the adsorbent use container 21 to the recovery and replenishment container.

[0109] Moreover, each function of the elevator control device 5, the monitoring device 40, and the information center 60 in the first and second embodiments is realized by a processing circuit. Fig. 8 is a configuration diagram showing a first example of a processing circuit that realizes each function of the elevator control device 5, the monitoring device 40, and the information center 60 in the first and second embodiments.

The processing circuit 200 of the second example includes a processor 201 and a memory 202.

[0112] In the processing circuit 200, each function of the elevator control device 5, the monitoring device 40, and the information center 60 is realized by software, firmware, or a combination of software and firmware. The software and firmware are written as programs and stored in the memory 202. The processor 201 realizes each function by reading and executing the programs stored in the memory 202.

[0113] It can be said that the programs stored in the memory 202 cause the computer to execute the procedures or methods of each of the above-mentioned parts. Here, the memory 202 is, for example, a non-volatile or volatile semiconductor memory such as a random access memory (RAM), a read only memory (ROM), a flash memory, an erasable programmable read only memory (EPROM), an electrically erasable and programmable read only memory (EEPROM), etc. In addition, a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, a DVD, etc. also fall under the category of the memory 202.

[0115] In this way, the processing circuitry can realize the functions of each of the above-mentioned units through hardware, software, firmware, or a combination of these.
