  Next, the electrical configuration of the air conditioning system in the apartment 10 will be described with reference to FIG. FIG. 2 is a block diagram showing an electrical configuration of the air conditioning system.

  As shown in FIG. 2, the air conditioning system includes a management server 41 as a management control unit that performs operation control of the common air conditioner 25 and each of the blowout adjustment units 34. The management server 41 is configured to include a microcomputer composed of a CPU and various memories, and is installed in, for example, a manager's room in the shared space 12. The management server 41 is connected to the common air conditioner 25 and each air outlet adjustment unit 34, and the management server 41 controls the operation of the common air conditioner 25 and each air outlet adjustment unit 34 by outputting a command signal.

  A door-to-door server 42 as a home server installed in each dwelling unit 11 is connected to the management server 41. Each door-to-door server 42 includes a microcomputer including a CPU and various memories, and each door-to-door server 42 is connected to a door-to-door operation panel 43 operated by a resident or the like. The door-to-door server 42 and the door-to-door operation panel 43 are integrally attached to the inner wall surface of the living room, for example, in a state of being housed in one case body in each dwelling unit 11.

  The door-to-door operation panel 43 is capable of setting a target temperature for the air-conditioning operation of the shared air conditioner 25 for the living space 13 of each dwelling unit 11, and setting information including the target temperature is sent to the door-to-door server 42. Output. The door-to-door server 42 calculates the amount of conditioned air necessary for setting the actual temperature of the living space 13 to the target temperature for each living space 13, and outputs the amount as a required amount to the management server 41. In this way, the management server 41 acquires the required amount of conditioned air for each living space 13 for each dwelling unit 11.

  The management server 41 is connected to a shared operation panel 44 operated by an administrator or the like, and the shared operation panel 44 is accommodated in the same case body as the management server 41 in the shared space 12, for example. The shared operation panel 44 is capable of setting a target temperature for the air conditioning operation of the shared air conditioner 25 for the shared space 12 and outputs setting information including the target temperature to the management server 41. The management server 41 calculates the amount of conditioned air necessary for setting the actual temperature of the shared space 12 to the target temperature, and acquires the amount as the required amount of the shared space 12.

  For the living space 13 of each dwelling unit 11, the required amount of conditioned air may be calculated by the management server 41 instead of the door-to-door server 42. In this case, it is preferable that the setting information is input to the management server 41 through the door-to-door server 42 from the door-to-door operation panel 43 in each dwelling unit 11.

  Further, the setting information acquired by the management server 41 may include target humidity for the living space 13 and the common space 12 of each dwelling unit 11. In this case, it is preferable to adjust the humidity of the living space 13 and the common space 12 by supplying conditioned air from the common air conditioner 25.

  When the conditioned air is supplied from the shared air conditioner 25 to the dwelling unit 11, the management server 41 sets the usage fee of the conditioned air according to the supply amount. That is, for the air conditioning of the dwelling unit 11 by the shared air conditioner 25, the billing amount is calculated by a pay-as-you-go system. Note that the management server 41 may set the air conditioning fee by a flat rate system or a fixed amount system.

  Here, the air conditioning control processing performed by the management server 41 in the air conditioning system will be described with reference to the flowchart of FIG. The management server 41 repeatedly executes the air conditioning control process at a predetermined cycle.

  In FIG. 3, in step S101, the required amount of conditioned air is acquired for each living space 13 for each dwelling unit 11, and in step S102, the required amount of conditioned air is acquired for the shared space 12.

  In step S103, the amount of conditioned air generated in the shared air conditioner 25 is calculated based on the required amount of conditioned air for each dwelling unit 11 and the shared space 12. In this case, the generated amount of conditioned air is the sum of the required amounts of conditioned air in each of the dwelling units 11 and the common space 12. In step S104, operation control of each blowing adjustment unit 34 is performed so that the supply amount of the conditioned air to each living space 13 and the common space 12 of each dwelling unit 11 becomes the respective required amount. In step S105, the operation control of the shared air conditioner 25 is performed so that the amount of conditioned air generated is the sum of the required amounts of conditioned air by the respective dwelling units 11 and the shared space 12.

  In step S106, the supply amount of the conditioned air from the common air conditioner 25 to each living space 13 is calculated for each dwelling unit 11, and the integrated supply amount in a predetermined period is calculated as the usage amount. In step S107, based on the integrated supply amount of the conditioned air, the integrated usage fee of the conditioned air supplied from the common air conditioner 25 is calculated for each unit as an air conditioning fee. Here, for example, a predetermined period for calculating the amount of air-conditioning air used is one month, and when one month has passed, information on the air-conditioning usage and the air-conditioning charge for that month is stored in the management server 41. The air conditioning usage amount and the air conditioning charge are reset. Then, the integration of the air conditioning usage amount and the air conditioning charge for the next month is started.

  In addition, the same amount of conditioned air as the required amount calculated for each living space 13 for each dwelling unit 11 is blown out from each blowing adjustment unit 34 of each dwelling unit 11. That is, for each dwelling unit 11, the required amount of conditioned air and the actual supply amount are the same value. Incidentally, a sensor for detecting the amount of conditioned air actually blown out from the door-to-door outlet 31 is provided at the door-side outlet 31, and the supply amount of the conditioned air to each dwelling unit 11 is calculated based on the detection signal of the sensor. It may be a configuration. Even in this case, it becomes possible to calculate the integrated supply amount and the integrated usage fee of the conditioned air for each dwelling unit 11 for each predetermined period.

  Incidentally, the cumulative amount of air-conditioning air used and the air-conditioning charge are displayed on a display device such as a display panel. In this case, the air conditioning fee may be displayed as an item different from the rent and the common service cost, or the total value of the rent may be displayed.

  Next, an example when the air conditioning control process is performed by the management server 41 will be described with reference to FIG. FIG. 4 is a timing chart for explaining an example of the air conditioning control process.

  Here, in the housing complex 10, the first dwelling unit 11 </ b> A, the second dwelling unit 11 </ b> B, and the third dwelling unit 11 </ b> C are included in the plurality of dwelling units 11, and the air conditioning for these dwelling units 11 </ b> A to 11 </ b> C and the common space 12 is the common air conditioner 25. It is set as the structure performed collectively by. In addition, in order to make it easy to understand the relationship between the amount of conditioned air supplied to the dwelling units 11A to 11C and the common space 12 and the amount of conditioned air generated by the common air conditioner 25, each of the dwelling units 11A to 11C and the common space 12 is provided. When there is a request for conditioned air, the required amount is assumed to be constant at a predetermined value.

  As shown in FIG. 4, the amount of conditioned air generated by the shared air conditioner 25 is the sum of the amounts of conditioned air supplied to the dwelling units 11 </ b> A to 11 </ b> C and the shared space 12. For example, in a time zone in which air conditioning is performed only by the first dwelling unit 11A, the amount of conditioned air generated by the shared air conditioner 25 is the same value as the supply amount to the first dwelling unit 11A. In this time zone, the conditioned air is blown out from the door outlet 31 of the first dwelling unit 11A, and the conditioned air is blown out from the second dwelling unit 11B, the third dwelling unit 11C, and the outlets 31 and 32 of the common space 12. Is controlled by the management server 41 so as to be stopped.

  Moreover, in the time zone when air conditioning is performed for all of the dwelling units 11A to 11C and the common space 12, the amount of conditioned air generated by the common air conditioner 25 is the amount of supply to the dwelling units 11A to 11C and the common space 12. Total. In this time zone, the operation control of each blowing adjustment unit 34 by the management server 41 is performed so that the conditioned air is blown out from the outlets 31 and 32 of the dwelling units 11A to 11C and the common space 12, respectively. The required amount of conditioned air in the dwelling units 11A to 11C and the common space 12 is determined so that the total value thereof is smaller than the rated output of the common air conditioner 25. The entire building can be air-conditioned.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  In the housing complex 10, the air conditioning of each dwelling unit 11 is performed collectively by the common air conditioner 25, and therefore the air conditioning equipment becomes complicated compared to the case where an air conditioner such as an air conditioner is installed for each dwelling unit 11. Can be suppressed. Moreover, it becomes easy to centrally manage the amount of conditioned air supplied from the common air conditioner to each dwelling unit, and an administrator such as the owner can easily charge the air conditioning fee to the resident. On the other hand, it is possible for the resident to save the trouble of installing an air conditioner in the self-dwelling unit when moving in, and to reduce the cost burden for installing the air conditioner.

  Moreover, when the rated output of the common air conditioner 25 is larger than the rated output of each air conditioner when the air conditioner is installed for each dwelling unit 11, there is a time when there is a dwelling unit 11 in the apartment house 10 where air conditioning is not performed. In the belt, the conditioned air that should be supplied to the dwelling unit can be supplied to the other dwelling units 11. That is, when the air conditioning capability of the shared air conditioner 25 is surplus in the entire apartment house, the surplus can be used effectively. Thereby, the time required for air conditioning of the dwelling unit 11 made into the air conditioning object can be shortened.

  As described above, the air conditioning equipment of the apartment house 10 can be suitably installed, and the air conditioning efficiency of the dwelling unit 11 that is the air conditioning target can be increased.

  Since each dwelling unit 11 is not provided with an air conditioner, unlike the configuration in which each dwelling unit 11 is provided with an indoor unit and an outdoor unit, the appearance of the housing complex 10 is enhanced by a large number of outdoor units installed for each dwelling unit 11. Can be avoided. Further, unlike the case where an air conditioner is installed in each dwelling unit 11, it is not necessary to perform maintenance work for the air conditioner for each dwelling unit 11, so that maintenance costs (running costs) can be reduced. Furthermore, when maintenance work is performed on the shared air conditioner 25, it is not necessary for the worker to enter the dwelling unit 11 or the resident is present for the work. Therefore, the maintenance work is troublesome for the manager and the worker. Can be eliminated.

  Since the air conditioning fee is calculated for each dwelling unit 11 in the management server 41, the administrator can easily charge the air conditioning fee to the resident.

  Since each dwelling unit 11 and the common space 12 can be set as the supply destination of the conditioned air from the common air conditioner 25, it is possible to supply the dwelling unit 11 with the conditioned air supplied to the common space 12. It becomes. Thereby, while being able to suppress that the air-conditioning air which is not required for the air conditioning of the common space 12 becomes surplus air, the air-conditioning efficiency of each dwelling unit 11 can be improved.

  In the configuration in which the supply amount of the conditioned air from the common air conditioner 25 to each dwelling unit 11 and the common space 12 is adjusted by the blowout adjustment unit 34, the blowout adjustment unit 34 takes in the outside air into the air conditioning duct 33 and takes in the conditioned air. It is possible to adjust the temperature. For this reason, it can suppress that the conditioned air supplied from the common air conditioner 25 to each dwelling unit 11 and the common space 12 is too hot or too cold.

[Second Embodiment]
Next, the second embodiment will be described with a focus on differences from the first embodiment. In the first embodiment, the amount of conditioned air generated by the shared air conditioner 25 is determined based on the required amount of conditioned air for each dwelling unit 11 and the shared space 12, but the second embodiment Then, the supply amount of the conditioned air to each dwelling unit 11 and the common space 12 is determined based on the generated amount of the conditioned air by the common air conditioner 25. FIG. 5 is a block diagram showing an electrical configuration of the air conditioning system in the present embodiment.

  In this embodiment, as shown in FIG. 5, a door-to-door air conditioner 51 such as a small air conditioner is installed for each dwelling unit 11. The door-to-door air conditioner 51 includes an outdoor unit installed outdoors, an indoor unit that generates conditioned air, and a blowout port that blows out the generated conditioned air, and the blowout port is integrated with the case body of the indoor unit. It has been provided. The door-to-door air conditioner 51 is disposed in the living space 13 provided with the door outlet 31 in each dwelling unit 11, and the living space 13 is conditioned air from at least one of the shared air-conditioner 25 and the door-to-air conditioner 51. Also air conditioning is to be performed. The door-to-air conditioner 51 is electrically connected to the door-to-door server 42, and the door-to-door server 42 controls the operation of the door-to-air conditioner 51 by outputting a command signal.

  The amount of conditioned air generated by the shared air conditioner 25 is limited according to the specified amount of power used each time. In the present embodiment, in the configuration in which the shared air conditioner 25 is operated by the power from the solar power generation device 21, the amount of conditioned air generated by the shared air conditioning device is limited according to the power generation amount of the solar power generation device 21. .

  Specifically, in the shared distribution board 16, the power supply path from the commercial power supply 15 to the shared air conditioner 25 is interrupted, and the power supply path from the solar power generation device 21 or the power storage device 22 to the shared air conditioner 25 is energized. The common air conditioner 25 is operated only by power feeding from the solar power generation device 21 or the power storage device 22. For this reason, when electric power is not stored in the power storage device 22, if the power supplied from the solar power generation device 21 to the shared air conditioner 25 is smaller than the rated power consumption of the shared air conditioner 25, the shared air conditioner 25 is rated. It cannot be operated, and the amount of conditioned air generated by the shared air conditioner 25 is limited to a value smaller than the rated output.

  In the configuration in which the amount of conditioned air generated by the shared air conditioner 25 is limited, the amount of conditioned air that can be generated by the shared air conditioner 25 (the amount that can be generated) is based on the total required amount of each dwelling unit 11 and the shared space 12. May be smaller. Therefore, in this air conditioning system, the conditioned air from the common air conditioner 25 is supplied to the common space 12 with priority over each dwelling unit 11, and the deficiency of the conditioned air is compensated by the individual air conditioner 51 in each dwelling unit 11. It is like that.

  Here, each air-conditioning control process performed by the management server 41 and the door-to-door server 42 will be described. First, the air conditioning control process performed by the management server 41 will be described with reference to the flowchart of FIG. The management server 41 repeatedly executes the air conditioning control process at a predetermined cycle.

  In FIG. 6, in step S <b> 201, the amount of conditioned air that can be generated by the common air conditioner 25 is calculated. For example, the power generation amount by the solar power generation device 21 is acquired, and the output of the common air conditioner 25 corresponding to the power generation amount is converted into the generation amount of conditioned air and calculated. Note that a sensor for detecting the amount of power generation is preferably provided for the solar power generation device 21. Further, the common air conditioner 25 may be provided with a sensor that detects the amount of conditioned air generated in the common air conditioner 25.

  In step S202, the required amount of conditioned air is acquired for each living space 13 for each dwelling unit 11, and the required amount of conditioned air is acquired for the shared space 12 in step S203. In step S204, it is determined whether or not the sum of the required amounts of each dwelling unit 11 and the common space 12 is zero. If it is zero, the common air conditioner 25 is not operated and the air conditioning control process is terminated. When it is not zero, it progresses to step S205 and it is determined whether the production | generation possible amount of the conditioned air by the common air conditioner 25 is more than the request | requirement amount of the conditioned air by the common space 12. FIG.

  When the amount of air conditioned air that can be generated by the shared air conditioner 25 is smaller than the required amount of the shared space 12, the process proceeds to step S206, and all the conditioned air generated by the shared air conditioner 25 is supplied to the shared space 12. Thus, operation control of each blowout adjustment unit 34 is performed so that it is not supplied to each dwelling unit 11. In step S207, operation control of the shared air conditioner 25 is performed so that the maximum amount of conditioned air that can be generated by the electric power supplied from the solar power generation device 21 to the shared air conditioner 25 is generated. Even if the amount of conditioned air generated by the shared air conditioner 25 is insufficient with respect to the required amount of the shared space 12 due to the processing of Steps S206 and S207, an amount of conditioned air close to the required amount of the shared space 12 enters the shared space 12. Therefore, the actual temperature of the shared space 12 can be brought close to the target temperature.

  For the conditioned air, if the amount that can be generated by the shared air conditioner 25 is equal to or greater than the required amount of the shared space 12, the process proceeds to step S208, and the difference between the generated amount and the required amount of the shared space 12 is determined as the surplus amount of conditioned air. calculate. In step S209, the operation state of each individual air conditioner 51 is acquired for each dwelling unit 11 through the individual door server 42. In this case, with regard to the door-to-door air conditioner 51, it is determined that one that is operating or preparing for operation is operated, and one that is not operating or not preparing for operation is determined not to be operated.

  In step S210, the living space 13 in which the door-to-door air conditioner 51 to be operated is installed is set as the supply destination of the conditioned air from the common air conditioner 25, and surplus of conditioned air is set to the living space 13 set as the supply destination. The distribution amount when the minutes are distributed is calculated. The distribution amount is set so as not to be larger than the required amount of the living space 13. In step S211, information about the distribution amount is notified to the door-to-door server 42.

  In step S212, the supply amount of the conditioned air from the shared air conditioner 25 to the shared space 12 becomes the required amount of the shared space 12, and the conditioned air is supplied from the shared air conditioner 25 to each living space 13 of each dwelling unit 11. Operation control of each blowing adjustment unit 34 is performed so that the supply amount becomes the distribution amount of each living space 13. In step S213, operation control of the shared air conditioner 25 is performed so as to generate the maximum amount of conditioned air that can be generated by the electric power supplied from the solar power generation device 21 to the shared air conditioner 25. By the processes of steps S212 and S213, the common space 12 is preferentially supplied over each dwelling unit 11, and surplus air that is not supplied to the common space 12 among the conditioned air is distributed to each dwelling unit 11.

  In step S214, the supply amount of the conditioned air from the common air conditioner 25 to each living space 13 is calculated for each dwelling unit 11, and the integrated supply amount in a predetermined period is calculated as the usage amount. In step S215, based on the integrated supply amount of the conditioned air, the integrated usage fee of the conditioned air supplied from the common air conditioner 25 is calculated for each unit as an air conditioning fee.

  Next, the air conditioning control processing performed by the door-to-door server 42 will be described with reference to the flowchart of FIG. The door-to-door server 42 repeatedly executes this air conditioning control process at a predetermined cycle.

  In FIG. 7, in step S <b> 301, the required amount of conditioned air is acquired for each living space 13. In step S302, a notification from the management server 41 is input to obtain information on the distribution amount of the conditioned air distributed from the shared air conditioner 25. In step S303, for each living space 13, it is determined whether or not the distribution amount is the same as the requested amount. If there is a living space 13 that is the same, the process proceeds to step S304, and the individual air conditioner 51 is set for the living space 13. Operation control of the individual air conditioner 51 is performed so that conditioned air is not supplied from the door.

  If the distribution amount is not the same as the requested amount, that is, if there is a living space 13 where the distributed amount is smaller than the requested amount, the process proceeds to step S305, and the living space 13 is shared with the supply amount of conditioned air from the individual air conditioner 51. Operation control of the door-to-door air conditioner 51 is performed so that the total amount with the distribution amount from the air conditioner 25 becomes the required amount.

  Next, an example in which the air conditioning control process is performed by the management server 41 and the door-to-door server 42 will be described with reference to FIG. FIG. 8 is a timing chart for explaining an example of the air conditioning control process.

  In addition, in order to make it easy to understand the relationship between the supply amount of the conditioned air to the dwelling units 11A to 11C and the common space 12 and the generation amount of the conditioned air in the common air conditioner 25 as in the first embodiment, the dwelling unit When there is a request for conditioned air for each of 11A to 11C and the shared space 12, the required amount is assumed to be constant at a predetermined value.

  In FIG. 8, the amount of conditioned air generated by the common air conditioner 25 has an upper limit depending on the amount of power generated by the solar power generation device 21. Here, for example, in summer, it is assumed that cooling operation is performed by the common air conditioner 25 or the door-to-door air conditioner 51, and the amount of conditioned air generated by the common air conditioner 25 during the daytime when there is a large amount of solar radiation. There are many times.

  In a time zone in which the amount of conditioned air generated by the shared air conditioner 25 is less than or equal to the required amount of the shared space 12 (dashed line N in the figure), the conditioned air of the shared air conditioner 25 is supplied to the shared space 12. It is not supplied to each dwelling unit 11. In this case, as for the shared space 12, the supply amount of the conditioned air from the shared air conditioner 25 is smaller than the required amount, and compared with the case where the supply amount is the same as the required amount, Although the time required for the actual temperature to reach the target temperature becomes longer, the actual temperature of the shared space 12 gradually approaches the target temperature. On the other hand, for each dwelling unit 11, the same amount of conditioned air as the requested amount is supplied from the door-to-door air conditioner 51. In this case, all the conditioned air in each dwelling unit 11 is covered by the individual air conditioners 51.

  In the time zone when the amount of conditioned air generated by the shared air conditioner 25 is larger than the required amount of the shared space 12, the conditioned air of the shared air conditioner 25 is supplied to both the shared space 12 and the dwelling unit 11. In this case, in the shared space 12, the supply amount of the conditioned air from the shared air conditioner 25 is the same as the requested amount, and the air conditioning by the shared air conditioner 25 is appropriately performed. On the other hand, for each dwelling unit 11, the surplus of conditioned air that has not been supplied from the shared air conditioner 25 to the shared space 12 is distributed and supplied. Here, when the amount of distribution is smaller than the required amount of each dwelling unit 11, the shortage of conditioned air is supplied from the individual air conditioner 51, and when the required amount and the distributed amount are the same, Since the conditioned air is covered by the common air conditioner 25, the operation of the door-to-door air conditioner 51 is stopped.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  Since the conditioned air generated by the shared air conditioner 25 is supplied to the shared space 12 with priority over each dwelling unit 11, even if there is an upper limit in the amount of conditioned air generated in the shared air conditioner 25, the shared space The inconvenience that 12 air conditioning is not performed can be avoided. Here, in the configuration in which the power supply source to the common air conditioner 25 is the solar power generation device 21, the amount of conditioned air generated by the common air conditioner 25 is limited by the amount of power generated by the solar power generation device 21. By setting the priority order to the supply destination of the conditioned air from the common air conditioner 25, it is possible to suitably perform air conditioning in a space with high priority.

  In the housing complex 10, since the dedicated air conditioner 51 is installed in each dwelling unit 11, even in the case where the supply of conditioned air from the common air conditioner 25 is stopped in each dwelling unit 11, the door-to-door air conditioner 51. Air conditioning can be performed by conditioned air from That is, even if the conditioned air generated by the common air conditioner 25 is supplied to the common space 12 with priority over the respective dwelling units 11, the air conditioning of each dwelling unit 11 can be suitably performed. Therefore, even if the rated output of the common air conditioner 25 is not so large as to allow the air conditioning of each dwelling unit 11 and the common space 12 of the apartment house 10, the air conditioning of each dwelling unit 11 and the common space 12 is performed by the common air conditioner 25 and the individual air conditioning. It can be suitably performed by the machine 51.

  In each dwelling unit 11, when the supply amount of the conditioned air from the common air conditioner 25 does not reach the required amount of the living space 13, the shortage is compensated by the conditioned air from the individual air conditioner 51. Compared to a configuration in which all of the required amount is covered by the conditioned air from the door-to-door air conditioner 51, the operating rate of the door-to-air conditioner 51 can be lowered. Since this reduces the burden on the door-to-door air conditioner 51, the life of the door-to-air air conditioner 51 can be extended.

  In the solar power generation device 21, electric power is created using natural energy called sunlight, and the electric power is supplied to the common air conditioner 25, so the common air conditioner 25 uses the commercial power from the commercial power supply 15. Air conditioning of each dwelling unit 11 and common space 12 can be performed without doing. As a result, the manager does not need to pay a utility charge for commercial power to the power company and the like, and thus can obtain income from the air conditioning charges collected for each dwelling unit 11.
