The indoor unit 2 includes an indoor unit side communication unit 20 that communicates with the control device 4 and a detection unit 21 that detects the number of people present in the room where the indoor unit 2 is disposed. The detection unit 21 includes an infrared sensor 51 that detects a person using infrared rays, and a detection unit motor 52 that drives the infrared sensor 51.
　室内機２は、第１のタイミングに検出部２１によって検出された数である第１数と第１のタイミングより後の第２のタイミングに検出部２１によって検出された数である第２数とを比較して第２数が第１数より大きいか否かを判定する数判定部２２を更に有する。数判定部２２は、第１数が１以上であるか否かも判定する。すなわち、数判定部２２は、第１数が０でないか否かも判定する。数判定部２２は、第２数から第１数を減じた数である第３数が第１数より大きいか否かも判定する。 The indoor unit 2 includes a first number that is a number detected by the detection unit 21 at a first timing, and a second number that is a number detected by the detection unit 21 at a second timing after the first timing. And a number determination unit 22 for determining whether or not the second number is greater than the first number. The number determination unit 22 also determines whether or not the first number is 1 or more. That is, the number determination unit 22 also determines whether the first number is not zero. The number determination unit 22 also determines whether or not a third number, which is a number obtained by subtracting the first number from the second number, is greater than the first number.
　室内機２は、ファン２３と、ファン２３を駆動するファン用モータ２４とを更に有する。 The indoor unit 2 further includes a fan 23 and a fan motor 24 that drives the fan 23.
　室内機２は、第２数が第１数より大きいと数判定部２２によって判定された場合、第２のタイミング以後に、暖房運転時においては設定温度を上げると共にファン２３の回転数を上げる制御を行い、冷房運転時においては設定温度を下げると共にファン２３の回転数を上げる制御を行う制御部２５を更に有する。 When the number determination unit 22 determines that the second number is larger than the first number, the indoor unit 2 increases the set temperature and increases the rotation speed of the fan 23 during the heating operation after the second timing. And a control unit 25 that controls to lower the set temperature and increase the rotational speed of the fan 23 during the cooling operation.
　第２数が第１数より大きく第１数が１以上であると数判定部２２によって判定された場合、制御部２５は、第２のタイミング以後に、暖房運転時においては、設定温度の上げ幅を第１数が０であるときの上げ幅より小さくすると共に、ファン２３の回転数の上げ幅を第１数が０であるときの上げ幅より小さくする制御を行う。冷房運転時においては、第２数が第１数より大きく第１数が１以上であると数判定部２２によって判定された場合、制御部２５は、第２のタイミング以後に、設定温度の下げ幅を第１数が０であるときの下げ幅より小さくすると共に、ファン２３の回転数の上げ幅を第１数が０であるときの上げ幅より小さくする制御を行う。 When the number determination unit 22 determines that the second number is larger than the first number and the first number is 1 or more, the control unit 25 increases the set temperature in the heating operation after the second timing. Is controlled to be smaller than the increasing width when the first number is 0, and smaller than the increasing width when the first number is 0. During the cooling operation, when the number determination unit 22 determines that the second number is greater than the first number and the first number is 1 or more, the control unit 25 reduces the set temperature after the second timing. Control is performed such that the width is made smaller than the lowered width when the first number is 0, and the raised speed of the fan 23 is made smaller than the raised width when the first number is 0.
　制御部２５は、第２数が第１数より大きく第１数が１以上であると数判定部２２によって判定された場合、以下の制御を行う。すなわち、第２数から第１数を減じた数である第３数が第１数より大きいと数判定部２２によって判定されたとき、制御部２５は、第２のタイミング以後に、暖房運転時においては、設定温度の上げ幅を第３数が第１数以下であるときの上げ幅より大きくすると共に、ファン２３の回転数の上げ幅を第３数が第１数以下であるときの上げ幅より大きくする制御を行う。冷房運転時においては、第３数が第１数より大きいと数判定部２２によって判定されたとき、制御部２５は、第２のタイミング以後に、設定温度の下げ幅を第３数が第１数以下であるときの下げ幅より大きくすると共に、ファン２３の回転数の上げ幅を第３数が第１数以下であるときの上げ幅より大きくする制御を行う。 The control unit 25 performs the following control when the number determination unit 22 determines that the second number is greater than the first number and the first number is 1 or more. That is, when the number determination unit 22 determines that the third number, which is the number obtained by subtracting the first number from the second number, is greater than the first number, the control unit 25 performs the heating operation after the second timing. , The increase range of the set temperature is made larger than the increase rate when the third number is less than or equal to the first number, and the increase rate of the rotational speed of the fan 23 is made larger than the increase rate when the third number is less than or equal to the first number. Take control. During the cooling operation, when the number determination unit 22 determines that the third number is greater than the first number, the control unit 25 sets the range of decrease in the set temperature to the first number after the second timing. Control is performed so that the amount of increase in the rotation speed of the fan 23 is greater than the amount of increase when the third number is less than or equal to the first number.
　室内機２は、フラップ２６と、フラップ２６を駆動するフラップ用モータ２７とを更に有する。制御部２５は、フラップ用モータ２７の動作を制御することによりフラップ２６の動作も制御する。制御部２５が行うフラップ２６の動作の制御については、後に室内機２の動作を説明する際に説明する。なお、図２では、１個のフラップ２６だけが示されているが、実施の形態１の室内機２は４個のフラップを有しており、図２におけるフラップ２６は４個のフラップを代表している。４個のフラップは、複数のフラップの一例である。ただし、室内機２には１個のフラップだけが設けられてもよい。室内機２に１個のフラップだけが設けられている場合、図２のフラップ２６は当該１個のフラップを示す。 The indoor unit 2 further includes a flap 26 and a flap motor 27 that drives the flap 26. The control unit 25 controls the operation of the flap 26 by controlling the operation of the flap motor 27. The control of the operation of the flap 26 performed by the control unit 25 will be described later when the operation of the indoor unit 2 is described. In FIG. 2, only one flap 26 is shown, but the indoor unit 2 of the first embodiment has four flaps, and the flap 26 in FIG. 2 represents four flaps. is doing. Four flaps are an example of a plurality of flaps. However, the indoor unit 2 may be provided with only one flap. When the indoor unit 2 is provided with only one flap, the flap 26 in FIG. 2 indicates the one flap.
　室内機２は、室内機２が配置される部屋への入室者がいない時間を計測する計測部２８と、計測部２８によって計測された時間があらかじめ決められた時間を超えたか否かを判定する時間判定部２９とを更に有する。第２のタイミングにおける第２数が第１のタイミングにおける第１数より大きく、第２のタイミング以降において当該部屋への入室者がいない場合を想定する。その場合、計測部２８は、検出部２１によって検出された数が第２数以下である状態が第２のタイミングから継続する時間を計測する。あらかじめ決められた時間は、例えば実験によって決定される。 The indoor unit 2 determines whether the time measured by the measuring unit 28 exceeds a predetermined time, and a measuring unit 28 that measures the time when there is no person entering the room in which the indoor unit 2 is placed. And a time determination unit 29. It is assumed that the second number at the second timing is larger than the first number at the first timing, and there is no person entering the room after the second timing. In that case, the measurement unit 28 measures the time during which the state where the number detected by the detection unit 21 is equal to or less than the second number continues from the second timing. The predetermined time is determined by experiment, for example.
　計測部２８によって計測された時間があらかじめ決められた時間を超えたと時間判定部２９によって判定された場合、制御部２５は、設定温度、ファン２３の回転数及びフラップ２６の動作を元に戻す制御を行う。上述の通り、実施の形態１の室内機２は４個のフラップを有しており、図２におけるフラップ２６は４個のフラップを代表しているので、制御部２５がフラップ２６の動作を元に戻す制御を行う場合、制御部２５は４個のフラップの各々の動作を元に戻す制御を行う。なお、室内機２に１個のフラップだけが設けられている場合、制御部２５がフラップ２６の動作を元に戻す制御を行うとき、制御部２５は１個のフラップの動作を元に戻す制御を行う。 When the time determination unit 29 determines that the time measured by the measurement unit 28 exceeds a predetermined time, the control unit 25 performs control to restore the set temperature, the rotational speed of the fan 23, and the operation of the flap 26. I do. As described above, the indoor unit 2 of the first embodiment has four flaps, and the flap 26 in FIG. 2 represents the four flaps. Therefore, the control unit 25 is based on the operation of the flap 26. When performing control to return to, the control unit 25 performs control to restore the operation of each of the four flaps. When the indoor unit 2 is provided with only one flap, when the control unit 25 performs control to restore the operation of the flap 26, the control unit 25 performs control to restore the operation of one flap. I do.

　すなわち、室内機側通信部２０、検出部２１、数判定部２２、制御部２５、計測部２８及び時間判定部２９を構成する少なくとも一部の構成要素がプロセッサ６２によって実現される場合、室内機２は、室内機側通信部２０、検出部２１、数判定部２２、制御部２５、計測部２８及び時間判定部２９を構成する一部の構成要素によって実行されるステップが結果的に実行されることになるプログラムを格納するためのメモリ６１を有する。メモリ６１に格納されるプログラムは、室内機側通信部２０、検出部２１、数判定部２２、制御部２５、計測部２８及び時間判定部２９を構成する一部の構成要素が実行する手順又は方法をコンピュータに実行させるものであるともいえる。 That is, when at least some of the constituent elements constituting the indoor unit side communication unit 20, the detection unit 21, the number determination unit 22, the control unit 25, the measurement unit 28, and the time determination unit 29 are realized by the processor 62, As a result, the steps executed by some of the components constituting the indoor unit side communication unit 20, the detection unit 21, the number determination unit 22, the control unit 25, the measurement unit 28, and the time determination unit 29 are executed as a result. It has a memory 61 for storing programs to be stored. The program stored in the memory 61 is a procedure executed by some components constituting the indoor unit side communication unit 20, the detection unit 21, the number determination unit 22, the control unit 25, the measurement unit 28, and the time determination unit 29, or It can be said that the method is executed by a computer.
　メモリ６１は、例えば、ＲＡＭ(Random　Access　Memory)、ＲＯＭ(Read　Only　Memory)、フラッシュメモリ、ＥＰＲＯＭ(Erasable　Programmable　Read　Only　Memory)、ＥＥＰＲＯＭ(Electrically　Erasable　Programmable　Read-Only　Memory)等の、不揮発性又は揮発性の半導体メモリ、磁気ディスク、フレキシブルディスク、光ディスク、コンパクトディスク、ミニディスク又はＤＶＤ(Digital　Versatile　Disk)等である。 The memory 61 is nonvolatile or volatile, for example, RAM (Random Access Memory), ROM (Read Only Memory), flash memory, EPROM (Erasable Programmable Read Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), etc. Semiconductor memory, magnetic disk, flexible disk, optical disk, compact disk, mini disk or DVD (Digital Versatile Disk).

Can be realized.
　図１に示す通り、制御装置４は受付部４０及び制御装置側通信部４２を有する。受付部４０は、室内機２の制御部２５が行う制御を実行させる指示を受け付ける。例えば、受付部４０は、制御装置４に設けられるボタン又はスイッチがユーザによって利用されることにより、ボタン又はスイッチを介してユーザからの当該指示を受け付ける。制御装置側通信部４２は、受付部４０が当該指示を受け付けた場合、当該指示を室内機２の室内機側通信部２０に送信する。室内機側通信部２０が制御装置側通信部４２から当該指示を受信した場合、制御部２５は実施の形態１の制御を行う。受付部４０及び制御装置側通信部４２の機能の一部又は、全部は処理回路６０と同等の機能を有する処理回路によって実現されてもよい。受付部４０及び制御装置側通信部４２の一部又は全部は、プロセッサ６２と同等の機能を有するプロセッサによって実現されてもよい。 As shown in FIG. 1, the control device 4 includes a reception unit 40 and a control device side communication unit 42. The accepting unit 40 accepts an instruction to execute control performed by the control unit 25 of the indoor unit 2. For example, the reception unit 40 receives the instruction from the user via the button or switch when the button or switch provided in the control device 4 is used by the user. When the receiving unit 40 receives the instruction, the control device side communication unit 42 transmits the instruction to the indoor unit side communication unit 20 of the indoor unit 2. When the indoor unit communication unit 20 receives the instruction from the control device communication unit 42, the control unit 25 performs the control of the first embodiment. Part or all of the functions of the receiving unit 40 and the control device side communication unit 42 may be realized by a processing circuit having functions equivalent to the processing circuit 60. Part or all of the receiving unit 40 and the control device side communication unit 42 may be realized by a processor having the same function as the processor 62.
　次に、室内機２の動作を説明する。以下では、制御装置４の受付部４０が室内機２の制御部２５が行う制御を実行させる指示を受け付けたことを想定する。図５は、実施の形態１に係る空調システム１が有する室内機２の動作の手順を示すフローチャートである。検出部２１は、室内機２が配置されている部屋に存在する人の数を検出する（Ｓ１）。数判定部２２は、第２のタイミングに検出部２１によって検出された数である第２数が第２のタイミングの直前の検出タイミングである第１のタイミングにおいて検出部２１によって検出された数である第１数より大きいか否かを判定する（Ｓ２）。以下では、第１数を「第１数Ｎ」と記載し、第２数を「第２数Ｍ」と記載する。図５のステップＳ２では、第２のタイミングに検出部２１によって検出された第２数Ｍは「今回の数Ｍ」と記載されており、第１のタイミングに検出部２１によって検出された第１数Ｎは「前回の数Ｎ」と記載されている。 Next, the operation of the indoor unit 2 will be described. Hereinafter, it is assumed that the receiving unit 40 of the control device 4 has received an instruction to execute control performed by the control unit 25 of the indoor unit 2. FIG. 5 is a flowchart showing a procedure of the operation of the indoor unit 2 included in the air conditioning system 1 according to the first embodiment. The detection unit 21 detects the number of people present in the room where the indoor unit 2 is arranged (S1). The number determination unit 22 is the number detected by the detection unit 21 at the first timing, which is the detection timing immediately before the second timing, the second number being the number detected by the detection unit 21 at the second timing. It is determined whether it is larger than a certain first number (S2). Hereinafter, the first number is described as “first number N”, and the second number is described as “second number M”. In Step S2 of FIG. 5, the second number M detected by the detection unit 21 at the second timing is described as “current number M”, and the first number detected by the detection unit 21 at the first timing is described. The number N is described as “previous number N”.
　数判定部２２は、第２数Ｍが第１数Ｎより大きいと判定した場合（Ｓ２でＹｅｓ）、第１数Ｎが「０」であるか否かを判定する（Ｓ３）。「０」は、零である。すなわち、数判定部２２は、第２数Ｍが第１数Ｎより大きいと判定した場合（Ｓ２でＹｅｓ）、第１数Ｎが１以上であるか否かを判定する（Ｓ３）。なお、第２数Ｍが第１数Ｎより大きいことは、第１のタイミングから第２のタイミングまでの間に室内機２が配置されている部屋の人の数が増加したことを意味する。すなわち、第２数Ｍが第１数Ｎより大きいことは、第１のタイミングから第２のタイミングまでの間に入室者がいたことを意味する。 When determining that the second number M is greater than the first number N (Yes in S2), the number determination unit 22 determines whether the first number N is “0” (S3). “0” is zero. That is, when the number determination unit 22 determines that the second number M is greater than the first number N (Yes in S2), the number determination unit 22 determines whether the first number N is 1 or more (S3). Note that the fact that the second number M is larger than the first number N means that the number of people in the room in which the indoor unit 2 is arranged has increased from the first timing to the second timing. That is, the fact that the second number M is larger than the first number N means that there was a person entering the room from the first timing to the second timing.
　第１数Ｎが「０」であると数判定部２２によって判定された場合（Ｓ３でＹｅｓ）、制御部２５は、第２のタイミング以後に、暖房運転時においては設定温度を３℃上げる制御を行い（Ｓ４）、冷房運転時においては設定温度を３℃下げる制御を行い（Ｓ４）、暖房運転時及び冷房運転時のいずれにおいてもファン２３の回転数を上げる制御を行う（Ｓ５）。第１数Ｎが「０」であることは、第１のタイミングに当該部屋には人は存在しておらず、第１のタイミングから第２のタイミングまでの間に当該部屋に人が入って第２のタイミングにおいて人が存在したことを意味する。すなわち、第１数Ｎが「０」であることは、第１のタイミングに当該部屋には人が存在しておらず、第２のタイミングにおいて入室者がいたことを意味する。 When the number determination unit 22 determines that the first number N is “0” (Yes in S3), the control unit 25 performs control to increase the set temperature by 3 ° C. during the heating operation after the second timing. (S4), control is performed to lower the set temperature by 3 ° C. during the cooling operation (S4), and control is performed to increase the rotational speed of the fan 23 during both the heating operation and the cooling operation (S5). If the first number N is “0”, there is no person in the room at the first timing, and there is no person in the room between the first timing and the second timing. It means that there was a person at the second timing. That is, if the first number N is “0”, it means that there is no person in the room at the first timing and there is a person entering the room at the second timing.
　入室者は、暖房運転時においては気温が低い外部から部屋に入室するため、冷房運転時においては気温が高い外部から部屋に入室するため、空調制御を入室前よりも強めることを求める傾向がある。そのため、制御部２５は、暖房運転時においては設定温度を３℃上げる制御を行い（Ｓ４）、ファン２３の回転数を上げる制御を行う（Ｓ５）。冷房運転時においては、制御部２５は、設定温度を３℃下げる制御を行い（Ｓ４）、ファン２３の回転数を上げる制御を行う（Ｓ５）。上記の「３℃」は、一例である。 People entering the room enter the room from the outside with a low temperature during heating operation, and enter the room from the outside with a high temperature during cooling operation, so there is a tendency to demand stronger air conditioning control than before entering the room . Therefore, the control part 25 performs control which raises setting temperature 3 degreeC at the time of heating operation (S4), and performs control which raises the rotation speed of the fan 23 (S5). During the cooling operation, the control unit 25 performs control to lower the set temperature by 3 ° C. (S4), and performs control to increase the rotational speed of the fan 23 (S5). The above “3 ° C.” is an example.
　上述の通り、制御部２５は、第２数Ｍが第１数Ｎより大きいと数判定部２２によって判定された場合、第２のタイミング以後に、暖房運転時においては設定温度を上げると共にファン２３の回転数を上げる制御を行い、冷房運転時においては設定温度を下げると共にファン２３の回転数を上げる制御を行う。 As described above, when the number determination unit 22 determines that the second number M is greater than the first number N, the control unit 25 increases the set temperature during the heating operation and the fan 23 after the second timing. In the cooling operation, control is performed to lower the set temperature and increase the rotational speed of the fan 23.
　第１数Ｎが「０」であると数判定部２２によって判定された場合（Ｓ３でＹｅｓ）は、第１のタイミングに当該部屋には人は存在しておらず、第１のタイミングから第２のタイミングまでの間に当該部屋に人が入って第２のタイミングにおいて人が存在したことを意味する。すなわち、第１数Ｎが「０」であると数判定部２２によって判定された場合（Ｓ３でＹｅｓ）、空調制御を求める者は第１のタイミングから第２のタイミングまでの間の入室者のみである。そのため、第１数Ｎが「０」であると数判定部２２によって判定された場合（Ｓ３でＹｅｓ）、当該入室者の要求だけが満たされればよい。 When the number determination unit 22 determines that the first number N is “0” (Yes in S3), there is no person in the room at the first timing, and the first number N starts from the first timing. It means that a person entered the room before the second timing and a person existed at the second timing. That is, when the number determination unit 22 determines that the first number N is “0” (Yes in S3), only those who enter the room from the first timing to the second timing are asked for air conditioning control. It is. Therefore, when the number determination unit 22 determines that the first number N is “0” (Yes in S3), only the request of the room occupant needs to be satisfied.
　したがって、第１数Ｎが「０」であると数判定部２２によって判定された場合（Ｓ３でＹｅｓ）、制御部２５は、第１数Ｎが「０」ではなく１以上であると数判定部２２によって判定された場合（Ｓ３でＮｏ）よりも、暖房運転時においては設定温度の上げ幅を大きくし、冷房運転時においては設定温度の下げ幅を大きくする制御を行う。加えて、制御部２５は、暖房運転時及び冷房運転時のいずれにおいても、第１数Ｎが１以上であると数判定部２２によって判定された場合（Ｓ３でＮｏ）よりも、ファン２３の回転数の上げ幅を大きくする制御を行う。その結果、当該入室者の要求は満たされる。なお、第１数Ｎが「０」ではなく１以上であると数判定部２２によって判定された場合（Ｓ３でＮｏ）は、第１のタイミングにおいても第２のタイミングにおいても当該部屋に人が存在していることを意味する。 Therefore, when the number determination unit 22 determines that the first number N is “0” (Yes in S3), the control unit 25 determines that the first number N is not “0” but 1 or more. Control is performed to increase the set temperature increase range during the heating operation and to increase the set temperature decrease range during the cooling operation, as compared to the case determined by the unit 22 (No in S3). In addition, the control unit 25 controls the fan 23 more than when the number determination unit 22 determines that the first number N is 1 or more in both the heating operation and the cooling operation (No in S3). Control to increase the increase range of the rotation speed. As a result, the request of the resident is satisfied. When the number determination unit 22 determines that the first number N is not “0” but 1 or more (No in S3), a person is placed in the room at both the first timing and the second timing. It means that it exists.
　数判定部２２は、第１数Ｎが「０」ではなく１以上であると判定した場合（Ｓ３でＮｏ）、第２数Ｍから第１数Ｎを減じた数である第３数が第１数Ｎより大きいか否かを判定する（Ｓ６）。以下では、第３数を「第３数（Ｍ－Ｎ）」と記載する。図５のステップＳ６では、第３数は（Ｍ－Ｎ）と記載されている。なお、第１数Ｎが１以上であることは、第１のタイミングに当該部屋に人が存在しており、第１のタイミングから第２のタイミングまでの間に当該部屋の人の数が増加したことを意味する。 When the number determination unit 22 determines that the first number N is not “0” but 1 or more (No in S3), the third number that is the number obtained by subtracting the first number N from the second number M is the first number. It is determined whether or not it is larger than one number N (S6). Hereinafter, the third number is referred to as “third number (MN)”. In step S6 of FIG. 5, the third number is described as (MN). Note that the first number N is 1 or more means that there is a person in the room at the first timing, and the number of persons in the room increases between the first timing and the second timing. Means that
　第３数（Ｍ－Ｎ）が第１数Ｎより大きいと数判定部２２によって判定された場合（Ｓ６でＹｅｓ）、制御部２５は、第２のタイミング以後に、暖房運転時においては設定温度を２℃上げる制御を行い（Ｓ７）、冷房運転時においては設定温度を２℃下げる制御を行い（Ｓ７）、暖房運転時及び冷房運転時のいずれにおいてもファン２３の回転数を上げる制御を行う（Ｓ８）。 When the number determination unit 22 determines that the third number (MN) is greater than the first number N (Yes in S6), the control unit 25 sets the set temperature during the heating operation after the second timing. (S7), control is performed to lower the set temperature by 2 ° C during the cooling operation (S7), and control is performed to increase the rotational speed of the fan 23 during both the heating operation and the cooling operation. (S8).
　第３数（Ｍ－Ｎ）が第１数Ｎより大きいことは、第１のタイミングから第２のタイミングまでの間に当該部屋に入った人の数が第１のタイミングにおいて当該部屋に存在した人の数より多いことを意味する。言い換えると、第３数（Ｍ－Ｎ）が第１数Ｎより大きいことは、第１のタイミングから第２のタイミングまでの間の入室者の数が第１のタイミングに当該部屋に存在していた元の在室者の数よりも多いことを意味する。第３数（Ｍ－Ｎ）が第１数Ｎ以下であることは、第１のタイミングから第２のタイミングまでの間の入室者の数が元の在室者の数以下であることを意味する。 The fact that the third number (MN) is larger than the first number N means that the number of people who entered the room between the first timing and the second timing was present in the room at the first timing. Means more than the number of people. In other words, if the third number (MN) is larger than the first number N, the number of visitors from the first timing to the second timing is present in the room at the first timing. Means more than the original number of people in the room. That the third number (MN) is less than or equal to the first number N means that the number of occupants between the first timing and the second timing is less than or equal to the number of original occupants. To do.
　そのため、第３数（Ｍ－Ｎ）が第１数Ｎより大きいと数判定部２２によって判定された場合（Ｓ６でＹｅｓ）、第１のタイミングから第２のタイミングまでの間の入室者のみが求める空調制御が行われると、空調制御が大きく変化し、変化後の空調制御は元の在室者に対して適切でなくなる。したがって、第３数（Ｍ－Ｎ）が第１数Ｎより大きいと数判定部２２によって判定された場合（Ｓ６でＹｅｓ）の空調制御の程度は、第１数Ｎが「０」であると数判定部２２によって判定された場合（Ｓ３でＹｅｓ）の空調制御の程度よりも弱い。 Therefore, when the number determination unit 22 determines that the third number (MN) is greater than the first number N (Yes in S6), only the visitors from the first timing to the second timing are When the required air conditioning control is performed, the air conditioning control changes greatly, and the changed air conditioning control is not appropriate for the original occupant. Accordingly, when the number determination unit 22 determines that the third number (MN) is greater than the first number N (Yes in S6), the degree of air conditioning control is that the first number N is “0”. It is weaker than the degree of air conditioning control when it is determined by the number determination unit 22 (Yes in S3).
　上述の通り、第３数（Ｍ－Ｎ）が第１数Ｎより大きいことは、第１のタイミングから第２のタイミングまでの間の入室者の数が第１のタイミングに当該部屋に存在していた元の在室者の数よりも多いことを意味する。すなわち、第２のタイミングにおいて、相対的に強い空調制御が行われることを希望する入室者の数が相対的に弱い空調制御が行われることを希望する元の在室者の数より多い。 As described above, when the third number (MN) is larger than the first number N, the number of occupants between the first timing and the second timing exists in the room at the first timing. It means more than the original number of people in the room. That is, at the second timing, the number of occupants who desire relatively strong air conditioning control is greater than the number of original occupants who desire relatively weak air conditioning control.
　そのため、第３数（Ｍ－Ｎ）が第１数Ｎより大きいと数判定部２２によって判定された場合（Ｓ６でＹｅｓ）の空調制御の程度は、第３数（Ｍ－Ｎ）が第１数Ｎ以下であると数判定部２２によって判定された場合（Ｓ６でＮｏ）の空調制御の程度よりも強い。上述の通り、第３数（Ｍ－Ｎ）が第１数Ｎ以下であることは、第１のタイミングから第２のタイミングまでの入室者の数が元の在室者の数以下であることを意味する。すなわち、第２のタイミングにおいて、相対的に強い空調制御が行われることを希望する入室者の数が相対的に弱い空調制御が行われることを希望する元の在室者の数以下である。 Therefore, when the number determination unit 22 determines that the third number (MN) is larger than the first number N (Yes in S6), the third number (MN) is the first number. It is stronger than the degree of air-conditioning control when the number determination unit 22 determines that the number is N or less (No in S6). As described above, the third number (MN) being equal to or less than the first number N means that the number of occupants from the first timing to the second timing is equal to or less than the number of original occupants. Means. That is, at the second timing, the number of occupants who desire relatively strong air conditioning control is less than or equal to the number of original occupants who desire relatively weak air conditioning control.
　したがって、第３数（Ｍ－Ｎ）が第１数Ｎより大きいと数判定部２２によって判定された場合（Ｓ６でＹｅｓ）、制御部２５は、第３数（Ｍ－Ｎ）が第１数Ｎ以下であると数判定部２２によって判定された場合（Ｓ６でＮｏ）よりも、暖房運転時においては設定温度の上げ幅を大きくし、冷房運転時においては設定温度の下げ幅を大きくする制御を行う。加えて、第３数（Ｍ－Ｎ）が第１数Ｎより大きいと数判定部２２によって判定された場合（Ｓ６でＹｅｓ）、制御部２５は、暖房運転時及び冷房運転時のいずれにおいても、第３数（Ｍ－Ｎ）が第１数Ｎ以下であると数判定部２２によって判定された場合（Ｓ６でＮｏ）よりも、ファン２３の回転数の上げ幅を大きくする制御を行う。 Therefore, when the number determination unit 22 determines that the third number (MN) is greater than the first number N (Yes in S6), the control unit 25 determines that the third number (MN) is the first number. Control for increasing the set temperature increase during heating operation and increasing the set temperature decrease during cooling operation than when the number determination unit 22 determines that it is N or less (No in S6). Do. In addition, when the number determination unit 22 determines that the third number (MN) is greater than the first number N (Yes in S6), the control unit 25 performs both the heating operation and the cooling operation. Then, the control for increasing the rotational speed of the fan 23 is performed larger than when the number determination unit 22 determines that the third number (MN) is equal to or less than the first number N (No in S6).
　その結果、室内機２の空調能力の変化が大きくなることが抑制され、ひいては第１のタイミングから第２のタイミングまでの間の入室者が求める空調制御に対する要求も満たされ、かつ、元の在室者の空調制御に対する要求も満たされる。上記の「２℃」は、一例である。 As a result, the change in the air conditioning capability of the indoor unit 2 is suppressed from increasing, and as a result, the requirements for the air conditioning control required by the occupant from the first timing to the second timing are satisfied, and The requirement for air conditioning control of the room is also satisfied. The above “2 ° C.” is an example.
　第３数（Ｍ－Ｎ）が第１数Ｎより大きくなく第１数Ｎ以下であると数判定部２２によって判定された場合（Ｓ６でＮｏ）、制御部２５は、第２のタイミング以後に、暖房運転時においては設定温度を１℃上げる制御を行い（Ｓ９）、冷房運転時においては設定温度を１℃下げる制御を行い（Ｓ９）、暖房運転時及び冷房運転時のいずれにおいてもファン２３の回転数を上げる制御を行う（Ｓ１０）。 When the number determination unit 22 determines that the third number (MN) is not greater than the first number N and equal to or less than the first number N (No in S6), the control unit 25 performs the second timing and thereafter. In the heating operation, control is performed to increase the set temperature by 1 ° C. (S9), and in the cooling operation, control is performed to decrease the set temperature by 1 ° C. (S9), and the fan 23 is used in both the heating operation and the cooling operation. Control is performed to increase the rotation speed (S10).
　更に言うと、第３数（Ｍ－Ｎ）が第１数Ｎ以下であると数判定部２２によって判定された場合（Ｓ６でＮｏ）、制御部２５は以下の制御を行う。すなわち、制御部２５は、暖房運転時においては設定温度を上げる制御を行うものの、設定温度の上げ幅を、第３数（Ｍ－Ｎ）が第１数Ｎより大きいと数判定部２２によって判定された場合（Ｓ６でＹｅｓ）の上げ幅よりも小さくする。制御部２５は、冷房運転時においては設定温度を下げる制御を行うものの、設定温度の下げ幅を、第３数（Ｍ－Ｎ）が第１数Ｎより大きいと数判定部２２によって判定された場合（Ｓ６でＹｅｓ）の下げ幅よりも小さくする。制御部２５は、ファン２３の回転数を上げる制御を行うものの、回転数の上げ幅を、第３数（Ｍ－Ｎ）が第１数Ｎより大きいと数判定部２２によって判定された場合（Ｓ６でＹｅｓ）の上げ幅よりも小さくする。 Furthermore, if the number determination unit 22 determines that the third number (MN) is equal to or less than the first number N (No in S6), the control unit 25 performs the following control. That is, the control unit 25 performs control for increasing the set temperature during the heating operation, but the number determination unit 22 determines that the third number (MN) is greater than the first number N for the increase range of the set temperature. In the case (Yes in S6). The control unit 25 performs control to lower the set temperature during the cooling operation, but the number determining unit 22 determines that the third number (MN) is greater than the first number N for the range of decrease in the set temperature. In case (Yes in S6), it is made smaller than the lowering width. Although the control unit 25 performs control to increase the rotation speed of the fan 23, the number determination unit 22 determines that the increase range of the rotation speed is greater than the first number N (S6) (S6). In the case of Yes), it is made smaller than the raising width.
　上述の通り、第３数（Ｍ－Ｎ）が第１数Ｎ以下であることは、第１のタイミングから第２のタイミングまでの間の入室者の数が元の在室者の数以下であることを意味する。そのため、上述のように、第３数（Ｍ－Ｎ）が第１数Ｎ以下であると数判定部２２によって判定された場合（Ｓ６でＮｏ）の空調制御の程度は、第３数（Ｍ－Ｎ）が第１数Ｎより大きいと数判定部２２によって判定された場合（Ｓ６でＹｅｓ）の空調制御の程度よりも弱い。その結果、第１のタイミングから第２のタイミングまでの間の入室者が求める空調制御に対する要求も満たされ、かつ、元の在室者の空調制御に対する要求も満たされる。上記の「１℃」は、一例である。 As described above, the third number (MN) being equal to or less than the first number N means that the number of visitors from the first timing to the second timing is equal to or less than the number of original occupants. It means that there is. Therefore, as described above, when the number determination unit 22 determines that the third number (MN) is equal to or less than the first number N (No in S6), the degree of air conditioning control is the third number (M -N) is weaker than the degree of air conditioning control when the number determination unit 22 determines that it is greater than the first number N (Yes in S6). As a result, the request for the air conditioning control required by the occupant between the first timing and the second timing is satisfied, and the request for the air conditioning control of the original occupant is also satisfied. The above “1 ° C.” is an example.
　ここで、第１数Ｎが「０」であると数判定部２２によって判定された場合（Ｓ３でＹｅｓ）を第１の場合と定義し、第３数（Ｍ－Ｎ）が第１数Ｎより大きいと数判定部２２によって判定された場合（Ｓ６でＹｅｓ）を第２の場合と定義し、第３数（Ｍ－Ｎ）が第１数Ｎ以下であると数判定部２２によって判定された場合（Ｓ６でＮｏ）を第３の場合と定義する。上述の説明から理解できる通り、第１の場合、第２の場合及び第３の場合のなかでは、第１の場合の空調制御の程度が最も強く、第３の場合の空調制御の程度が最も弱い。 Here, the case where the number determination unit 22 determines that the first number N is “0” (Yes in S3) is defined as the first case, and the third number (MN) is the first number N. The case where the number is determined to be larger by the number determination unit 22 (Yes in S6) is defined as the second case, and the number determination unit 22 determines that the third number (MN) is equal to or less than the first number N. The case (No in S6) is defined as the third case. As can be understood from the above description, in the first case, the second case and the third case, the degree of air conditioning control in the first case is the strongest, and the degree of air conditioning control in the third case is the strongest. weak.
　すなわち、３段階の空調制御の程度のなかでは、第１のタイミングに当該部屋に人が存在しておらず、第１のタイミングから第２のタイミングまでの間に当該部屋に人が入って第２のタイミングにおいて人が存在した場合、空調制御の程度は最も強い。第１のタイミングから第２のタイミングまでの間に当該部屋に入った人の数が第１のタイミングにおいて当該部屋に存在した人の数以下である多い場合、空調制御の程度は最も弱い。第１のタイミングから第２のタイミングまでの間に当該部屋に入った人の数が第１のタイミングにおいて当該部屋に存在した人の数より多い場合、空調制御の程度は最も強い制御と最も弱い制御との中間である。 That is, among the three stages of air conditioning control, there is no person in the room at the first timing, and the person enters the room between the first timing and the second timing. When there is a person at the timing of 2, the degree of air conditioning control is the strongest. When the number of people who have entered the room between the first timing and the second timing is less than or equal to the number of people who were in the room at the first timing, the degree of air conditioning control is the weakest. When the number of people who entered the room between the first timing and the second timing is larger than the number of people who existed in the room at the first timing, the degree of air conditioning control is the strongest control and the weakest It is intermediate to control.
　そのため、図５では、ステップＳ５において「変更量：大」という文言が記載されており、ステップＳ８において「変更量：中」という文言が記載されており、ステップＳ１０において「変更量：小」という文言が記載されている。「変更量：大」は３段階の空調制御の程度のなかで最も強い空調制御に対応しており、「変更量：小」は最も弱い空調制御に対応しており、「変更量：中」は最も強い空調制御と最も弱い空調制御との中間の空調制御に対応している。 Therefore, in FIG. 5, the word “change amount: large” is described in step S5, the word “change amount: medium” is described in step S8, and the word “change amount: small” is described in step S10. The wording is written. “Change amount: large” corresponds to the strongest air conditioning control among the three levels of air conditioning control, “change amount: small” corresponds to the weakest air conditioning control, and “change amount: medium” Corresponds to air conditioning control between the strongest air conditioning control and the weakest air conditioning control.
　ステップＳ５、ステップＳ８及びステップＳ１０の各動作が行われると、室内機２の動作はステップＳ１１に移行する。ステップＳ１１において、フラップ２６の動作が制御される。ステップＳ１１において行われる動作については、図６から図１０を用いて後述する。 If each operation | movement of step S5, step S8, and step S10 is performed, operation | movement of the indoor unit 2 will transfer to step S11. In step S11, the operation of the flap 26 is controlled. The operation performed in step S11 will be described later with reference to FIGS.
　上述の通り、ステップＳ２において、数判定部２２は、第２数Ｍが第１数Ｎより大きいか否かを判定する。第２数Ｍが第１数Ｎより大きいことは、第１のタイミングから第２のタイミングまでの間に室内機２が配置されている部屋の人の数が増加したことを意味する。すなわち、第１のタイミングから第２のタイミングまでの間に入室者がいたことを意味する。したがって、第２数Ｍが第１数Ｎより大きくないこと、つまり第２数Ｍが第１数Ｎ以下であることは、第１のタイミングから第２のタイミングまでの間に入室者がいなかったことを意味する。 As described above, in step S2, the number determination unit 22 determines whether or not the second number M is greater than the first number N. The fact that the second number M is larger than the first number N means that the number of people in the room in which the indoor unit 2 is arranged has increased from the first timing to the second timing. That is, it means that there was a person entering the room from the first timing to the second timing. Therefore, the fact that the second number M is not larger than the first number N, that is, that the second number M is equal to or less than the first number N means that there were no occupants between the first timing and the second timing. Means that.
　第２数Ｍが第１数Ｎより大きくないと数判定部２２によって判定された場合（Ｓ２でＮｏ）、計測部２８は、当該部屋への入室者がいない時間を計測する（Ｓ１２）。時間判定部２９は、計測部２８によって計測された時間があらかじめ決められた時間を超えたか否かを判定する（Ｓ１３）。言い換えると、時間判定部２９は、計測部２８によって計測された時間があらかじめ決められた時間を経過したか否かを判定する（Ｓ１３）。計測部２８によって計測された時間があらかじめ決められた時間を超えたと時間判定部２９によって判定された場合（Ｓ１３でＹｅｓ）、制御部２５は、設定温度、ファン２３の回転数及びフラップ２６の動作を元に戻す制御を行う（Ｓ１４）。 When it is determined by the number determination unit 22 that the second number M is not larger than the first number N (No in S2), the measurement unit 28 measures the time when there is no person entering the room (S12). The time determination unit 29 determines whether or not the time measured by the measurement unit 28 exceeds a predetermined time (S13). In other words, the time determination unit 29 determines whether or not the time measured by the measurement unit 28 has passed a predetermined time (S13). When the time determination unit 29 determines that the time measured by the measurement unit 28 exceeds a predetermined time (Yes in S13), the control unit 25 sets the set temperature, the rotational speed of the fan 23, and the operation of the flap 26. Control to restore the original is performed (S14).
　第２のタイミングにおける第２数Ｍが第１のタイミングにおける第１数Ｎより大きく、設定温度、ファン２３の回転数及びフラップ２６の動作を変更する制御が行われた後において、当該部屋への入室者がいない場合を想定する。その場合、計測部２８は、検出部２１によって検出された数が第２数Ｍ以下である状態が第２のタイミングから継続する時間を計測する。計測部２８によって計測された時間があらかじめ決められた時間を超えたと時間判定部２９によって判定された場合、制御部２５は、設定温度、ファン２３の回転数及びフラップ２６の動作を元の動作に戻す制御を行う。 After the second number M at the second timing is larger than the first number N at the first timing, and the control for changing the set temperature, the rotation speed of the fan 23 and the operation of the flap 26 is performed, Assume that there are no visitors. In that case, the measurement unit 28 measures the time during which the state where the number detected by the detection unit 21 is equal to or less than the second number M continues from the second timing. When the time determination unit 29 determines that the time measured by the measurement unit 28 exceeds a predetermined time, the control unit 25 changes the set temperature, the rotational speed of the fan 23, and the operation of the flap 26 to the original operation. Control to return.
　計測部２８によって計測された時間があらかじめ決められた時間を超えていないと時間判定部２９によって判定された場合（Ｓ１３でＮｏ）と、ステップＳ１４の動作が行われた場合、室内機２の動作は終了する。ステップＳ１１の動作が行われた場合、計測部２８は計測時間をリセットし（Ｓ１５）、室内機２の動作は終了する。 The operation of the indoor unit 2 when the time determination unit 29 determines that the time measured by the measurement unit 28 does not exceed the predetermined time (No in S13), or when the operation of step S14 is performed. Ends. When the operation of step S11 is performed, the measurement unit 28 resets the measurement time (S15), and the operation of the indoor unit 2 ends.

　次に、ステップＳ１１において行われる動作について説明する。図１０は、実施の形態１に係る空調システム１が有する室内機２の動作のうちの図５のステップＳ１１において行われる動作の手順を示すフローチャートである。検出部２１、数判定部２２及び制御部２５は、第１区域７１、第２区域７２、第３区域７３及び第４区域７４の各々について、以下の通りに動作する。 Next, the operation performed in step S11 will be described. FIG. 10 is a flowchart showing the procedure of the operation performed in step S11 of FIG. 5 among the operations of the indoor unit 2 included in the air conditioning system 1 according to the first embodiment. The detection unit 21, the number determination unit 22, and the control unit 25 operate as follows for each of the first area 71, the second area 72, the third area 73, and the fourth area 74.
　検出部２１は、存在する人の数を検出する。以下では、第１区域７１において第１のタイミングに検出部２１によって検出された数を第４数と定義し、第１区域７１において第２のタイミングに検出部２１によって検出された数を第５数と定義する。数判定部２２は、第２のタイミングに検出部２１によって検出された数である第５数が「０」であるか否かを判定する（Ｓ１６）。第５数が「０」であると数判定部２２によって判定された場合（Ｓ１６でＹｅｓ）、制御部２５はフラップ２６ａを閉じる制御を行う（Ｓ１７）。第５数が０であることは、第１区域７１に人が存在しないことを意味する。 Detecting unit 21 detects the number of people present. Hereinafter, the number detected by the detection unit 21 at the first timing in the first zone 71 is defined as the fourth number, and the number detected by the detection unit 21 at the second timing in the first zone 71 is the fifth number. It is defined as a number. The number determination unit 22 determines whether or not the fifth number, which is the number detected by the detection unit 21 at the second timing, is “0” (S16). When the number determination unit 22 determines that the fifth number is “0” (Yes in S16), the control unit 25 performs control to close the flap 26a (S17). If the fifth number is 0, it means that there is no person in the first area 71.
　数判定部２２は、第５数が「０」ではなく１以上であると判定した場合（Ｓ１６でＮｏ）、第１のタイミングに検出部２１によって検出された数である第４数が「０」であるか否かを判定する（Ｓ１８）。第４数が「０」であると数判定部２２によって判定された場合（Ｓ１８でＹｅｓ）、制御部２５は、フラップ２６ａからフラップ２６ｄのうちのフラップ２６ａのみをスイングさせる制御を行う（Ｓ１９）。第４数が「０」であることは、第１区域７１において元の在室者は存在せず、新たな入室者しか存在しないことを意味する。 When the number determination unit 22 determines that the fifth number is not “0” but 1 or more (No in S16), the fourth number, which is the number detected by the detection unit 21 at the first timing, is “0”. Is determined (S18). When the number determination unit 22 determines that the fourth number is “0” (Yes in S18), the control unit 25 performs control to swing only the flap 26a from the flap 26a to the flap 26d (S19). . When the fourth number is “0”, it means that there is no original occupant in the first area 71 and only new occupants exist.
　第４数が「０」ではなく１以上であると数判定部２２によって判定された場合（Ｓ１８でＮｏ）、制御部２５はフラップ２６ａの動作を維持する制御を行う（Ｓ２０）。第４数が「０」ではなく１以上であると数判定部２２によって判定された場合（Ｓ１８でＮｏ）は、第１区域７１において元の在室者も新たな入室者も存在することを意味する。 If the number determination unit 22 determines that the fourth number is not “0” but 1 or more (No in S18), the control unit 25 performs control to maintain the operation of the flap 26a (S20). If the number determination unit 22 determines that the fourth number is not “0” but 1 or more (No in S18), it is determined that there are both an original occupant and a new occupant in the first area 71. means.
　すなわち、制御部２５は、第１区域７１において、人が存在しない場合にフラップ２６ａを閉じる制御を行い（Ｓ１７）、新たな入室者しか存在しない場合にフラップ２６ａをスイングさせる制御を行い（Ｓ１９）、元の在室者も新たな入室者も存在する場合にフラップ２６ａの動作を維持する制御を行う（Ｓ２０）。第２区域７２、第３区域７３及び第４区域７４の各々において、制御部２５は、第１区域７１に対応するフラップ２６ａに対して行う制御と同一の制御を、フラップ２６ｂ、フラップ２６ｃ、フラップ２６ｄに対して行う。 That is, the control unit 25 performs control to close the flap 26a when there is no person in the first section 71 (S17), and performs control to swing the flap 26a when only a new person is present (S19). When both the original occupant and the new occupant exist, control is performed to maintain the operation of the flap 26a (S20). In each of the second area 72, the third area 73, and the fourth area 74, the control unit 25 performs the same control as the control performed on the flap 26a corresponding to the first area 71, the flap 26b, the flap 26c, and the flap. 26d.
　上述の通り、室内機２は、部屋に人が存在する状態から当該部屋に人が入った場合において暖房運転時においては設定温度を上げると共にファン２３の回転数を上げる制御を行い、冷房運転時においては設定温度を下げると共にファン２３の回転数を上げる制御を行う。すなわち、室内機２は、空調制御の対象の部屋に既に人が存在していて当該部屋に新たな人が入った場合において、当該部屋に対して適切な空調制御を行うことができるという効果を奏する。 As described above, the indoor unit 2 performs control to increase the set temperature and increase the rotation speed of the fan 23 during the heating operation when a person enters the room from the state where the person exists in the room, and during the cooling operation. In, control is performed to lower the set temperature and increase the rotational speed of the fan 23. That is, the indoor unit 2 has an effect that when a person already exists in the room subject to air conditioning control and a new person enters the room, the air conditioning control can be appropriately performed on the room. Play.
　また、室内機２は、以下の３個の場合の各々において、空調制御の程度を異ならせる。すなわち、第１のタイミングに当該部屋には人が存在しておらず、第１のタイミングから第２のタイミングまでの間に当該部屋に人が入って第２のタイミングにおいて人が存在した第１の場合、３段階の空調制御のなかで、室内機２は空調制御の程度を最も強くする。第１のタイミングから第２のタイミングまでの間に当該部屋に入った人の数が第１のタイミングにおいて当該部屋に存在した人の数以下である第３の場合、室内機２は空調制御の程度を最も弱くする。第１のタイミングから第２のタイミングまでの間に当該部屋に入った人の数が第１のタイミングにおいて当該部屋に存在した人の数より多い第２の場合、室内機２は空調制御の程度を第１の場合の程度と第３の場合の程度との中間の程度にする。 In addition, the indoor unit 2 varies the degree of air conditioning control in each of the following three cases. That is, there is no person in the room at the first timing, and there is a person in the room from the first timing to the second timing, and there is a person at the second timing. In the case of, the indoor unit 2 makes the degree of air conditioning control the strongest among the three stages of air conditioning control. In the third case where the number of people who have entered the room between the first timing and the second timing is equal to or less than the number of people who have been in the room at the first timing, the indoor unit 2 performs air conditioning control. Make the degree the weakest. In the second case where the number of people who entered the room between the first timing and the second timing is greater than the number of people who existed in the room at the first timing, the indoor unit 2 has a degree of air conditioning control. Is set to an intermediate level between the level in the first case and the level in the third case.
　上述の室内機２による制御により、室内機２は、第１の場合、第２の場合及び第３の場合のいずれにおいても、元の在室者に対しても新たな入室者に対しても適切に空調制御を行うことができる。 By the control by the indoor unit 2 described above, the indoor unit 2 can be used for both the original occupant and the new occupant in the first case, the second case, and the third case. Air conditioning control can be performed appropriately.
　加えて、室内機２は、各区域において、人が存在しない場合にフラップ２６を閉じる制御を行う。当該制御により、室内機２は、人が存在しない区域に対して風を送る無駄な動作を行わないことができる。また、室内機２は、各区域において、新たな入室者しか存在しない場合にフラップ２６をスイングさせる制御を行い、元の在室者も新たな入室者も存在する場合にフラップ２６の動作を維持する制御を行う。つまり、室内機２は、各区域において、各区域に存在する人に対して適切に風を向かわせることができる。 In addition, the indoor unit 2 performs control to close the flap 26 when no person is present in each area. By the said control, the indoor unit 2 can not perform the useless operation | movement which sends a wind with respect to the area where a person does not exist. The indoor unit 2 controls the swing of the flap 26 when there are only new occupants in each zone, and maintains the operation of the flap 26 when both the original occupants and new occupants exist. Control. That is, the indoor unit 2 can appropriately direct the wind in each area to the person existing in each area.
　さらに、室内機２は、室内機２が配置される部屋への入室者がいない時間があらかじめ決められた時間を超えた場合、設定温度、ファン２３の回転数及びフラップ２６の動作を元に戻す制御を行う。当該制御により、室内機２は、通常より過剰な空調制御によって室内機２が配置されている部屋を冷やしすぎること及び暖めすぎることを抑制することができる。 Furthermore, the indoor unit 2 restores the set temperature, the rotational speed of the fan 23, and the operation of the flap 26 when the time when there is no person entering the room in which the indoor unit 2 is disposed exceeds a predetermined time. Take control.

It may be realized by a processor.
　次に、実施の形態２に係る空調システム１Ａの動作を説明する。以下では、制御装置４ａの受付部４０が、室内機２ａ、室内機２ｂ、室内機２ｃ及び室内機２ｄの各々の制御部が行う制御を実行させる指示を受け付けたことを想定する。まず、空調システム１Ａが有する制御装置４ａの動作を説明する。図１４は、実施の形態２に係る空調システム１Ａが有する制御装置４ａの動作の手順を示すフローチャートである。室内機判定部４１は、制御装置４ａに接続されている室内機の個数を判定する（Ｓ２１）。制御装置４ａに接続されている室内機の個数が１個であると室内機判定部４１によって判定された場合（Ｓ２１でＹｅｓ）、制御装置側通信部４２は、制御装置４ａに接続されている室内機の個数が１個であることを示す個数情報を、制御装置４ａに接続されている室内機に送信する（Ｓ２２）。 Next, the operation of the air conditioning system 1A according to Embodiment 2 will be described. Hereinafter, it is assumed that the reception unit 40 of the control device 4a has received an instruction to execute control performed by the control units of the indoor unit 2a, the indoor unit 2b, the indoor unit 2c, and the indoor unit 2d. First, the operation of the control device 4a included in the air conditioning system 1A will be described. FIG. 14 is a flowchart illustrating the operation procedure of the control device 4a included in the air conditioning system 1A according to the second embodiment. The indoor unit determination unit 41 determines the number of indoor units connected to the control device 4a (S21). When the indoor unit determination unit 41 determines that the number of indoor units connected to the control device 4a is one (Yes in S21), the control device side communication unit 42 is connected to the control device 4a. The number information indicating that the number of indoor units is one is transmitted to the indoor units connected to the control device 4a (S22).
　制御装置４ａに接続されている室内機の個数が１個でないと室内機判定部４１によって判定された場合（Ｓ２１でＮｏ）、制御装置側通信部４２は、制御装置４ａに接続されているすべての室内機に対して、当該室内機に対応する領域に存在する人の数を特定する情報を送信することを要求し、すべての室内機から、当該室内機に対応する領域に存在する人の数を特定する情報を受信する（Ｓ２３）。 When the indoor unit determination unit 41 determines that the number of indoor units connected to the control device 4a is not one (No in S21), the control device side communication unit 42 is all connected to the control device 4a. Requesting the indoor unit to transmit information specifying the number of persons existing in the area corresponding to the indoor unit, and from all the indoor units, Information specifying the number is received (S23).
　算出部４３は、制御装置側通信部４２によって受信された情報をもとに、大部屋８０に存在する人の数の合計を算出する（Ｓ２４）。制御装置側数判定部４４は、第１のタイミングに複数の室内機のすべての検出部によって検出された数である第１合計と第２のタイミングに複数の室内機のすべての検出部によって検出された数である第２合計とを比較し、第２合計が第１合計より大きいか否かを判定する（Ｓ２５）。以下では、第１合計を「第１合計Ｎｍａｘ」と記載し、第２合計を「第２合計Ｍｍａｘ」と記載する。図１４のステップＳ２５では、第１のタイミングに複数の室内機のすべての検出部によって検出された数である第１合計は「前回の合計Ｎｍａｘ」と記載されており、第２のタイミングに複数の室内機のすべての検出部によって検出された数である第２合計は「今回の合計Ｍｍａｘ」と記載されている。 The calculation unit 43 calculates the total number of people present in the large room 80 based on the information received by the control device side communication unit 42 (S24). The control device-side number determination unit 44 detects the first total which is the number detected by all the detection units of the plurality of indoor units at the first timing and all the detection units of the plurality of indoor units at the second timing. The second sum, which is the number obtained, is compared to determine whether the second sum is greater than the first sum (S25). Hereinafter, the first total is referred to as “first total Nmax”, and the second total is referred to as “second total Mmax”. In step S25 of FIG. 14, the first total, which is the number detected by all the detection units of the plurality of indoor units at the first timing, is described as “previous total Nmax”. The second total which is the number detected by all the detection units of the indoor unit is described as “current total Mmax”.
　第２合計Ｍｍａｘが第１合計Ｎｍａｘより大きいと制御装置側数判定部４４によって判定された場合（Ｓ２５でＹｅｓ）、制御装置側通信部４２は、第２合計Ｍｍａｘが第１合計Ｎｍａｘより大きいことを示す増加情報を複数の室内機のすべてに送信する（Ｓ２６）。第２合計Ｍｍａｘが第１合計Ｎｍａｘ以下であると制御装置側数判定部４４によって判定された場合（Ｓ２５でＮｏ）、制御装置側通信部４２は、第２合計Ｍｍａｘが第１合計Ｎｍａｘ以下であることを示す不増加情報を複数の室内機のすべてに送信する（Ｓ２７）。 When the control device side number determination unit 44 determines that the second total Mmax is greater than the first total Nmax (Yes in S25), the control device side communication unit 42 determines that the second total Mmax is greater than the first total Nmax. Is transmitted to all of the plurality of indoor units (S26). When the control device side number determination unit 44 determines that the second total Mmax is equal to or less than the first total Nmax (No in S25), the control device side communication unit 42 determines that the second total Mmax is equal to or less than the first total Nmax. The non-increasing information indicating the presence is transmitted to all of the plurality of indoor units (S27).
　次に、実施の形態２に係る空調システム１Ａが有する室内機２ａの動作を説明する。上述の通り、室内機２ｂ、室内機２ｃ及び室内機２ｄの各々は室内機２ａと同一の機能を有し、以下では室内機２ａの動作を説明するので、室内機２ｂ、室内機２ｃ及び室内機２ｄの各々の動作の説明を省略する。図１５は、実施の形態２に係る空調システム１Ａが有する室内機２ａの動作の手順を示すフローチャートである。 Next, the operation of the indoor unit 2a included in the air conditioning system 1A according to Embodiment 2 will be described. As described above, each of the indoor unit 2b, the indoor unit 2c, and the indoor unit 2d has the same function as the indoor unit 2a, and the operation of the indoor unit 2a will be described below, so the indoor unit 2b, the indoor unit 2c, and the indoor unit A description of each operation of the machine 2d is omitted. FIG. 15 is a flowchart illustrating an operation procedure of the indoor unit 2a included in the air conditioning system 1A according to the second embodiment.
　検出部２１ａは、室内機２ａに対応する第１領域８１に存在する人の数を検出する（Ｓ３１）。制御部２５ａは、室内機側通信部５３ａが制御装置４ａの制御装置側通信部４２から増加情報を受信したか否かを判定する（Ｓ３２）。室内機側通信部５３ａが増加情報を受信しないと制御部２５ａによって判定された場合（Ｓ３２でＮｏ）、室内機２ａの動作はステップＳ４６に移行する。なお、室内機側通信部５３ａが個数情報を受信したと制御部２５ａによって判定された場合、室内機２ａは実施の形態１の室内機２と同一の動作を行う。 The detecting unit 21a detects the number of people present in the first area 81 corresponding to the indoor unit 2a (S31). The control unit 25a determines whether or not the indoor unit side communication unit 53a has received the increase information from the control device side communication unit 42 of the control device 4a (S32). When the control unit 25a determines that the indoor unit communication unit 53a does not receive the increase information (No in S32), the operation of the indoor unit 2a proceeds to step S46. When the control unit 25a determines that the indoor unit side communication unit 53a has received the number information, the indoor unit 2a performs the same operation as the indoor unit 2 of the first embodiment.
　ステップＳ４６の動作は、実施の形態１において説明した図５のステップＳ１２の動作と同一である。ステップＳ４６の動作の後、室内機２ａの動作はステップＳ４７に移行し、ステップＳ４７の動作の後、室内機２ａの動作はステップＳ４８に移行する。ステップＳ４７の動作は図５のステップＳ１３の動作と同一であり、ステップＳ４８の動作は図５のステップＳ１４の動作と同一である。 The operation in step S46 is the same as the operation in step S12 in FIG. 5 described in the first embodiment. After the operation of step S46, the operation of the indoor unit 2a proceeds to step S47, and after the operation of step S47, the operation of the indoor unit 2a proceeds to step S48. The operation in step S47 is the same as the operation in step S13 in FIG. 5, and the operation in step S48 is the same as the operation in step S14 in FIG.
　すなわち、計測部２８ａは検出部２１ａによって検出された数が第２数以下である状態が第２のタイミングから継続する時間を計測し、時間判定部２９ａは検出部２１ａによって計測された時間があらかじめ決められた時間を超えたか否かを判定する。計測部２８ａによって計測された時間があらかじめ決められた時間を超えたと時間判定部２９ａによって判定された場合、制御部２５ａは、設定温度、ファン２３ａの回転数及びフラップ２６ａの動作を元に戻す制御を行う。 In other words, the measuring unit 28a measures the time during which the state where the number detected by the detecting unit 21a is equal to or smaller than the second number continues from the second timing, and the time determining unit 29a determines in advance the time measured by the detecting unit 21a. It is determined whether or not a predetermined time has been exceeded. When the time determination unit 29a determines that the time measured by the measurement unit 28a exceeds a predetermined time, the control unit 25a performs control to restore the set temperature, the rotational speed of the fan 23a, and the operation of the flap 26a. I do.
　ステップＳ３２において、室内機側通信部５３ａが増加情報を受信したと制御部２５ａによって判定された場合（Ｓ３２でＹｅｓ）、室内機側数判定部２２ａは、第２のタイミングに検出部２１ａによって検出された数である第２数が第２のタイミングの直前の検出タイミングである第１のタイミングにおいて検出部２１ａによって検出された数である第１数より大きいか否かを判定する（Ｓ３３）。以下では、実施の形態２の第１数を「第１数ｎ」と記載し、実施の形態２の第２数を「第２数ｍ」と記載する。図１５のステップＳ３３では、第１のタイミングに検出部２１ａによって検出された第１数は「前回の数ｎ」と記載されており、第２のタイミングに検出部２１ａによって検出された第２数は「今回の数ｍ」と記載されている。 In step S32, when the control unit 25a determines that the indoor unit side communication unit 53a has received the increase information (Yes in S32), the indoor unit side number determination unit 22a is detected by the detection unit 21a at the second timing. It is determined whether or not the second number that is the number is greater than the first number that is the number detected by the detection unit 21a at the first timing that is the detection timing immediately before the second timing (S33). Hereinafter, the first number in the second embodiment is described as “first number n”, and the second number in the second embodiment is described as “second number m”. In step S33 of FIG. 15, the first number detected by the detection unit 21a at the first timing is described as “previous number n”, and the second number detected by the detection unit 21a at the second timing. Is described as “the current number m”.
　第２数ｍが第１数ｎ以下であると室内機側数判定部２２ａによって判定された場合（Ｓ３３でＮｏ）、室内機２ａの動作はステップＳ４６に移行する。第２数ｍが第１数ｎより大きいと室内機側数判定部２２ａによって判定された場合（Ｓ３３でＹｅｓ）、制御部２５ａは、室内機側通信部５３ａが増加情報を受信したひとつ前のタイミングに、室内機側通信部５３ａが増加情報を受信したか否かを判定する（Ｓ３４）。 If the indoor unit side number determination unit 22a determines that the second number m is equal to or less than the first number n (No in S33), the operation of the indoor unit 2a proceeds to step S46. When it is determined by the indoor unit side number determination unit 22a that the second number m is greater than the first number n (Yes in S33), the control unit 25a immediately before the indoor unit side communication unit 53a receives the increase information. At the timing, it is determined whether or not the indoor unit side communication unit 53a has received the increase information (S34).
　制御部２５ａは、室内機側通信部５３ａが増加情報を受信したひとつ前のタイミングに、室内機側通信部５３ａが個数情報を受信せずに不増加情報を受信したと判定した場合（Ｓ３４でＮｏ）、第２のタイミング以後に、暖房運転時においては設定温度を３℃上げる制御を行い（Ｓ３５）、冷房運転時においては設定温度を３℃下げる制御を行い（Ｓ３５）、暖房運転時及び冷房運転時のいずれにおいてもファン２３ａの回転数を上げる制御を行う（Ｓ３６）。ステップＳ３５の動作の内容は実施の形態１のステップＳ４の動作の内容と同一であり、ステップＳ３６の動作の内容は実施の形態１のステップＳ５の動作の内容と同一である。 When the control unit 25a determines that the indoor unit side communication unit 53a has received the non-increase information without receiving the number information at the timing immediately before the indoor unit side communication unit 53a has received the increase information (in S34) No) After the second timing, control is performed to increase the set temperature by 3 ° C. during the heating operation (S35), and control is performed to decrease the set temperature by 3 ° C. during the cooling operation (S35). In any cooling operation, control is performed to increase the rotational speed of the fan 23a (S36). The content of the operation in step S35 is the same as the content of the operation in step S4 of the first embodiment, and the content of the operation in step S36 is the same as the content of the operation in step S5 of the first embodiment.
　室内機側通信部５３ａが増加情報を受信したひとつ前のタイミングに、室内機側通信部５３ａが増加情報を受信せずに不増加情報を受信したと制御部２５ａによって判定された場合（Ｓ３４でＮｏ）は、大部屋８０において人の数が増加し、室内機２ａに対応する第１領域８１においても人の数が増加したことを意味する。 When the control unit 25a determines that the indoor unit side communication unit 53a has received non-increase information without receiving the increase information at the timing immediately before the indoor unit side communication unit 53a receives the increase information (in S34) No) means that the number of people in the large room 80 has increased, and the number of people has also increased in the first area 81 corresponding to the indoor unit 2a.
　そのため、大部屋８０において、実施の形態１において説明した最も強い空調制御が要求される。つまり、制御部２５ａは、室内機側通信部５３ａが増加情報を受信したひとつ前のタイミングに、室内機側通信部５３ａが増加情報を受信せずに不増加情報を受信したと制御部２５ａによって判定された場合（Ｓ３４でＮｏ）、実施の形態１において説明した最も強い空調制御を行う。 Therefore, in the large room 80, the strongest air conditioning control described in the first embodiment is required. That is, when the indoor unit communication unit 53a receives the non-increase information without receiving the increase information at the timing immediately before the indoor unit communication unit 53a receives the increase information, the control unit 25a If determined (No in S34), the strongest air conditioning control described in the first embodiment is performed.
　室内機側通信部５３ａが増加情報を受信したひとつ前のタイミングに、室内機側通信部５３ａが増加情報を受信したと制御部２５ａによって判定された場合（Ｓ３４でＹｅｓ）、室内機側数判定部２２ａは、第１数ｎが「０」であるか否かを判定する（Ｓ３７）。第１数ｎが「０」であると室内機側数判定部２２ａによって判定された場合（Ｓ３７でＹｅｓ）、制御部２５ａは、第２のタイミング以後に、暖房運転時においては設定温度を３℃上げる制御を行い（Ｓ３８）、冷房運転時においては設定温度を３℃下げる制御を行い（Ｓ３８）、暖房運転時及び冷房運転時のいずれにおいてもファン２３ａの回転数を上げる制御を行う（Ｓ３９）。 When the control unit 25a determines that the indoor unit side communication unit 53a has received the increase information at the timing immediately before the indoor unit side communication unit 53a receives the increase information (Yes in S34), the indoor unit side number determination The unit 22a determines whether or not the first number n is “0” (S37). When the indoor unit side number determination unit 22a determines that the first number n is “0” (Yes in S37), the control unit 25a sets the set temperature to 3 during the heating operation after the second timing. A control for increasing the temperature is performed (S38), a control for lowering the set temperature by 3 ° C is performed during the cooling operation (S38), and a control for increasing the rotational speed of the fan 23a is performed during both the heating operation and the cooling operation (S39). ).
　ステップＳ３７の動作の内容は、実施の形態１のステップＳ３の動作の内容と同一である。そのため、第１数ｎが「０」であると室内機側数判定部２２ａによって判定された場合（Ｓ３７でＹｅｓ）、制御部２５ａは実施の形態１において説明した最も強い空調制御を行う。 The content of the operation in step S37 is the same as the content of the operation in step S3 of the first embodiment. Therefore, when the indoor unit side number determination unit 22a determines that the first number n is “0” (Yes in S37), the control unit 25a performs the strongest air conditioning control described in the first embodiment.
　室内機側数判定部２２ａは、第１数ｎが１以上であると判定した場合（Ｓ３７でＮｏ）、第２数ｍから第１数ｎを減じた数である第３数が第１数ｎより大きいか否かを判定する（Ｓ４０）。以下では、第３数を「第３数（ｍ－ｎ）」と記載する。図１５のステップＳ４０では、第３数は（ｍ－ｎ）と記載されている。 When the indoor unit number determination unit 22a determines that the first number n is 1 or more (No in S37), the third number that is the number obtained by subtracting the first number n from the second number m is the first number. It is determined whether it is larger than n (S40). Hereinafter, the third number is referred to as “third number (mn)”. In step S40 of FIG. 15, the third number is described as (mn).
　第３数（ｍ－ｎ）が第１数ｎより大きいと室内機側数判定部２２ａによって判定された場合（Ｓ４０でＹｅｓ）、制御部２５ａは、第２のタイミング以後に、暖房運転時においては設定温度を２℃上げる制御を行い（Ｓ４１）、冷房運転時においては設定温度を２℃下げる制御を行い（Ｓ４１）、暖房運転時及び冷房運転時のいずれにおいてもファン２３ａの回転数を上げる制御を行う（Ｓ４２）。ステップＳ４０の動作の内容は、実施の形態１のステップＳ６の動作の内容と同一である。そのため、第３数（ｍ－ｎ）が第１数ｎより大きいと室内機側数判定部２２ａによって判定された場合（Ｓ４０でＹｅｓ）、制御部２５ａは実施の形態１において説明した中間の空調制御を行う。 When the indoor unit side number determination unit 22a determines that the third number (mn) is greater than the first number n (Yes in S40), the control unit 25a performs the heating operation after the second timing. Controls to raise the set temperature by 2 ° C. (S41), and controls to lower the set temperature by 2 ° C. during the cooling operation (S41), and increases the rotation speed of the fan 23a in both the heating operation and the cooling operation. Control is performed (S42). The content of the operation in step S40 is the same as the content of the operation in step S6 of the first embodiment. Therefore, when the indoor unit side number determination unit 22a determines that the third number (mn) is greater than the first number n (Yes in S40), the control unit 25a performs the intermediate air conditioning described in the first embodiment. Take control.
　第３数（ｍ－ｎ）が第１数ｎ以下であると室内機側数判定部２２ａによって判定された場合（Ｓ４０でＮｏ）、制御部２５ａは、第２のタイミング以後に、暖房運転時においては設定温度を１℃上げる制御を行い（Ｓ４３）、冷房運転時においては設定温度を１℃下げる制御を行い（Ｓ４３）、暖房運転時及び冷房運転時のいずれにおいてもファン２３の回転数を上げる制御を行う（Ｓ４４）。ステップＳ４０の動作の内容は、実施の形態１のステップＳ６の動作の内容と同一である。そのため、第３数（ｍ－ｎ）が第１数ｎ以下であると室内機側数判定部２２ａによって判定された場合（Ｓ４０でＮｏ）、制御部２５ａは実施の形態１において説明した最も弱い空調制御を行う。 When the indoor unit side number determination unit 22a determines that the third number (mn) is equal to or less than the first number n (No in S40), the control unit 25a performs the heating operation after the second timing. Is controlled to increase the set temperature by 1 ° C. (S43), and is controlled to decrease the set temperature by 1 ° C. during the cooling operation (S43), and the rotational speed of the fan 23 is controlled in both the heating operation and the cooling operation. The control to raise is performed (S44). The content of the operation in step S40 is the same as the content of the operation in step S6 of the first embodiment. Therefore, when the indoor unit side number determination unit 22a determines that the third number (mn) is equal to or less than the first number n (No in S40), the control unit 25a is the weakest described in the first embodiment. Perform air conditioning control.
　すなわち、第２合計が第１合計より大きいと制御装置４ａの制御装置側数判定部４４によって判定された場合、室内機２ａの制御部２５ａは、第２数ｍが第１数ｎより大きいと室内機側数判定部２２ａによって判定されたとき、第２のタイミング以後に、暖房運転時においては設定温度を上げると共にファン２３ａの回転数を上げる制御を行い、冷房運転時においては設定温度を下げると共にファン２３ａの回転数を上げる制御を行う。 That is, when it is determined by the control device side number determination unit 44 of the control device 4a that the second total is greater than the first total, the control unit 25a of the indoor unit 2a determines that the second number m is greater than the first number n. When determined by the indoor unit side number determination unit 22a, after the second timing, control is performed to increase the set temperature and increase the rotation speed of the fan 23a during the heating operation, and to decrease the set temperature during the cooling operation. At the same time, control is performed to increase the rotational speed of the fan 23a.
　更に言うと、以下の場合Ａ及び場合Ｂでは、制御部２５ａは、暖房運転時においては、設定温度の上げ幅を第１数ｎが１以上であるときの上げ幅より大きくすると共に、ファン２３ａの回転数の上げ幅を第１数ｎが１以上であるときの上げ幅より大きくする制御を行い、冷房運転時においては、設定温度の下げ幅を第１数ｎが１以上であるときの下げ幅より大きくすると共に、ファン２３ａの回転数の上げ幅を第１数ｎが１以上であるときの上げ幅より大きくする制御を行う。 Furthermore, in the following cases A and B, the controller 25a makes the set temperature increase range larger than the increase range when the first number n is 1 or more during the heating operation, and the rotation of the fan 23a. The control is performed so that the number increase range is larger than the increase amount when the first number n is 1 or more. During cooling operation, the set temperature decrease range is larger than the decrease range when the first number n is 1 or more. At the same time, a control is performed to increase the rotational speed of the fan 23a to be larger than that when the first number n is 1 or more.
　場合Ａは、第２数ｍが第１数ｎより大きいと室内機側数判定部２２ａによって判定された場合であって、制御装置側数判定部４４による第２合計が第１合計より大きいとの判定の直前の判定において第２合計が第１合計以下であると制御装置側数判定部４４によって判定された場合である。場合Ｂは、第２数ｍが第１数ｎより大きいと室内機側数判定部２２ａによって判定された場合であって、制御装置側数判定部４４による第２合計が第１合計より大きいとの判定の直前の判定において第２合計が第１合計より大きいと制御装置側数判定部４４によって判定されていて、かつ、第１数ｎが「０」であると室内機側数判定部２２ａによって判定された場合である。 Case A is a case where the indoor unit side number determination unit 22a determines that the second number m is greater than the first number n, and the second sum by the control device side number determination unit 44 is greater than the first sum. This is a case where the control device-side number determination unit 44 determines that the second total is equal to or less than the first total in the determination immediately before the determination. Case B is a case where the indoor unit side number determination unit 22a determines that the second number m is greater than the first number n, and the second sum by the control device side number determination unit 44 is greater than the first sum. When the second total is greater than the first total in the determination immediately before the determination, the controller side number determination unit 44 determines that the first number n is “0”, and the indoor unit side number determination unit 22a. It is a case where it determines by.
　更に、以下の場合Ｃでは、制御部２５ａは、暖房運転時においては、設定温度の上げ幅を、第１数ｎが「０」であるときの上げ幅より小さく第３数（ｍ－ｎ）が第１数ｎ以下であるときの上げ幅より大きく設定すると共に、ファン２３ａの回転数の上げ幅を、第１数ｎが「０」であるときの上げ幅より小さく第３数（ｍ－ｎ）が第１数ｎ以下であるときの上げ幅より大きく設定する制御を行う。加えて、場合Ｃでは、制御部２５ａは、冷房運転時においては、設定温度の上げ幅を、第１数ｎが「０」であるときの下げ幅より小さく第３数（ｍ－ｎ）が第１数ｎ以下であるときの下げ幅より大きく設定すると共に、ファン２３ａの回転数の上げ幅を、第１数ｎが「０」であるときの上げ幅より小さく第３数（ｍ－ｎ）が第１数ｎ以下であるときの上げ幅より大きく設定する制御を行う。 Further, in the following case C, the control unit 25a, during the heating operation, makes the set temperature increase smaller than the increase when the first number n is “0”, and the third number (mn) is the first increase. The number of rotations of the fan 23a is set to be larger than the amount of increase when the number n is less than or equal to n, and the amount of increase of the rotation speed of the fan 23a is smaller than the amount of increase when the first number n is “0”. Control is performed so as to be set larger than the amount of increase when the number is n or less. In addition, in the case C, during the cooling operation, the control unit 25a increases the set temperature by less than the decrease range when the first number n is “0”, and the third number (mn) is the third number (mn). It is set larger than the lowering width when the number is less than or equal to n, and the rotational speed increase of the fan 23a is smaller than the increasing speed when the first number n is “0”, and the third number (mn) is the first number. Control is performed so that it is set larger than the amount of increase when the number is less than one number n.
　場合Ｃは、第２数ｍが第１数ｎより大きいと室内機側数判定部２２ａによって判定された場合であって、制御装置側数判定部４４による第２合計が第１合計より大きいとの判定の直前の判定において第２合計が第１合計より大きいと制御装置側数判定部４４によって判定されていて、第１数ｎが１以上であると室内機側数判定部２２ａによって判定され、かつ、第２数ｍから第１数ｎを減じた数である第３数（ｍ－ｎ）が第１数ｎより大きいと室内機側数判定部２２ａによって判定された場合である。 Case C is a case where the indoor unit side number determination unit 22a determines that the second number m is greater than the first number n, and the second sum by the control device side number determination unit 44 is greater than the first sum. In the determination immediately before the determination, the control device side number determination unit 44 determines that the second total is larger than the first total, and the indoor unit side number determination unit 22a determines that the first number n is 1 or more. In this case, the indoor unit number determination unit 22a determines that the third number (mn), which is the number obtained by subtracting the first number n from the second number m, is greater than the first number n.
　ステップＳ３６、Ｓ３９、Ｓ４２及びＳ４４の各動作が行われると、室内機２ａの動作はステップＳ４５に移行する。ステップＳ４５の動作は図５のステップＳ１１の動作と同一である。 If each operation | movement of step S36, S39, S42, and S44 is performed, operation | movement of the indoor unit 2a will transfer to step S45. The operation in step S45 is the same as the operation in step S11 in FIG.
　すなわち、室内機側数判定部２２ａは、第２のタイミングに検出部２１ａによって検出された数である第５数が「０」であるか否かを判定する。室内機側数判定部２２ａは、第２のタイミングに検出部２１ａによって検出された数である第５数が１以上であると共に、第１のタイミングに検出部２１ａによって検出された数である第４数が「０」であるか否かを更に判定する。室内機側数判定部２２ａは、第２のタイミングに検出部２１ａによって検出された数である第５数が１以上であると共に、第１のタイミングに検出部２１ａによって検出された数である第４数が１以上であるか否かを更に判定する。 That is, the indoor unit number determination unit 22a determines whether or not the fifth number, which is the number detected by the detection unit 21a at the second timing, is “0”. The indoor unit side number determination unit 22a has a fifth number that is the number detected by the detection unit 21a at the second timing being 1 or more and a number that is detected by the detection unit 21a at the first timing. It is further determined whether or not the four number is “0”. The indoor unit side number determination unit 22a has a fifth number that is the number detected by the detection unit 21a at the second timing being 1 or more and a number that is detected by the detection unit 21a at the first timing. It is further determined whether the four number is 1 or more.
　制御部２５ａは、第５数が「０」であると室内機側数判定部２２ａによって判定された場合、フラップ２６ｅを閉じる制御を行う。制御部２５ａは、第５数が１以上であると共に第４数が「０」であると室内機側数判定部２２ａによって判定された場合、フラップ２６ｅをスイングさせる制御を行う。制御部２５ａは、第５数が１以上であると共に第４数が１以上であると室内機側数判定部２２ａによって判定された場合、フラップ２６ｅの動作を維持する制御を行う。 When the indoor unit side number determination unit 22a determines that the fifth number is “0”, the control unit 25a performs control to close the flap 26e. When the indoor unit side number determination unit 22a determines that the fifth number is 1 or more and the fourth number is “0”, the control unit 25a performs control to swing the flap 26e. If the indoor unit side number determination unit 22a determines that the fifth number is 1 or more and the fourth number is 1 or more, the control unit 25a performs control to maintain the operation of the flap 26e.
　上述の通り、空調システム１Ａでは、各室内機は、第２合計Ｍｍａｘが第１合計Ｎｍａｘより大きいことを示す増加情報を受信した場合、当該増加情報を受信するひとつ前に受信した情報が増加情報ではないとき、大部屋８０の全体における空調制御の程度は弱いので、３段階の空調制御のなかで最も強い空調制御を行う。すなわち、各室内機は、大部屋８０に存在する人が増えたことを示す増加情報を受信した場合、当該増加情報を受信するひとつ前に受信した情報が大部屋８０に存在する人が増えたことを示す増加情報ではないとき、大部屋８０における空調制御の程度は弱いので、最も強い空調制御を行う。つまり、空調システム１Ａは、大部屋８０の全体を考慮して空調制御を適切に行うことができる。 As described above, in the air conditioning system 1A, when each indoor unit receives increase information indicating that the second total Mmax is greater than the first total Nmax, the information received immediately before receiving the increase information is the increase information. If not, since the degree of air conditioning control in the entire large room 80 is weak, the strongest air conditioning control is performed among the three stages of air conditioning control. That is, when each indoor unit receives the increase information indicating that the number of persons existing in the large room 80 has increased, the number of persons whose information received immediately before receiving the increase information has increased in the large room 80 has increased. When the increase information does not indicate that, the air conditioning control in the large room 80 is weak, so the strongest air conditioning control is performed. That is, the air conditioning system 1A can appropriately perform air conditioning control in consideration of the entire large room 80.
　複数の室内機を有する空調システム１Ａによって得られる効果のうちの、当該複数の室内機が配置される大部屋８０の全体を考慮した上述の効果以外の効果は、実施の形態１に空調システム１によって得られる効果と同じである。 Among the effects obtained by the air conditioning system 1A having a plurality of indoor units, effects other than the above-described effects in consideration of the entire large room 80 in which the plurality of indoor units are arranged are described in the first embodiment. Is the same as the effect obtained by.
　なお、実施の形態２の空調システム１Ａでは、室内機２ａ、室内機２ｂ、室内機２ｃ及び室内機２ｄの各々は、配線によって制御装置４ａと接続されている。しかしながら、室内機２ａ、室内機２ｂ、室内機２ｃ及び室内機２ｄのうちの少なくともひとつの室内機が制御装置４ａと接続されていればよい。当該ひとつの室内機が制御装置４ａと接続されている場合、他の室内機は当該ひとつの室内機と通信可能に設定される。 In the air conditioning system 1A of the second embodiment, each of the indoor unit 2a, the indoor unit 2b, the indoor unit 2c, and the indoor unit 2d is connected to the control device 4a by wiring. However, at least one of the indoor unit 2a, the indoor unit 2b, the indoor unit 2c, and the indoor unit 2d only needs to be connected to the control device 4a. When the one indoor unit is connected to the control device 4a, the other indoor units are set to be communicable with the one indoor unit.
