Description

空気調和システム、空気調和装置、制御方法及びプログラムAir conditioning system, air conditioning device, control method and program
　本開示は、空気調和システム、空気調和装置、制御方法及びプログラムに関する。 This disclosure relates to an air conditioning system, an air conditioning device, a control method, and a program.
　ユーザが存在する空間の環境を調整してユーザの集中度の低下を防止する空気調和システムが開発されている。例えば、特許文献１には、ユーザの体温から集中度を推定し、集中度が低下した際に、集中度の低下を防止するように空間の環境を調整する空気調和システムが開示されている。集中度の低下があるか否かの判別については、ユーザの体温変化率が閾値以上になった時を「集中度の低下あり」と判断している。例えば、ユーザの体温の変化率が閾値以上に上昇したとき、「集中度の低下あり」との判断をして、使用者の温冷感を低下させる運転を行う。 Air conditioning systems have been developed that adjust the environment of the space in which the user is present to prevent a decrease in the user's level of concentration. For example, Patent Document 1 discloses an air conditioning system that estimates the level of concentration from the user's body temperature, and adjusts the environment of the space to prevent a decrease in the level of concentration when the level of concentration decreases. To determine whether or not there is a decrease in the level of concentration, a "decline in concentration has occurred" is determined when the rate of change in the user's body temperature exceeds a threshold value. For example, when the rate of change in the user's body temperature rises above a threshold value, it is determined that there is a "decline in concentration" and an operation is performed to reduce the user's thermal sensation.
特開２０２０－３９４４３号公報JP 2020-39443 A
　ユーザの体温から集中度を推定する手法は、信頼度が低く、誤検出が多いという問題がある。例えば、ユーザが作業を短期間で完了させようと集中している場合に、高揚感、緊張感などが絡み合い、同時にストレスを感じて体温が短時間で上昇することがある。このような場合、体温に基づいて推定する手法では、ユーザの集中度が高いにもかかわらず、「集中度の低下あり」と判断してしまう恐れがある。この場合、集中度を上げるように温冷感を下げる運転を行うと、ストレスによる冷や汗で寒気を感じ、ユーザの集中度を低下させてしまう。 Methods that estimate the level of concentration from a user's body temperature have the problem of low reliability and frequent false positives. For example, when a user is concentrating to complete a task in a short period of time, a combination of elation and tension can cause stress and a rise in body temperature in a short period of time. In such cases, methods that estimate based on body temperature may determine that the user's level of concentration is "decreasing," even when the user is highly concentrated. In this case, if the device is operated to reduce thermal sensation in order to increase the level of concentration, the user will feel chills from the cold sweat caused by stress, and this will decrease the user's level of concentration.
　また、特許文献１では、温冷感を下げる手法として、室温を下げること、ユーザの位置における風量を調整することを例示しているが、これらの調整だけでは、ユーザの集中度を向上するには、不十分であり、改善が求められる。 In addition, Patent Document 1 gives examples of methods for reducing the sensation of warmth and coldness, such as lowering the room temperature and adjusting the air volume at the user's position, but these adjustments alone are insufficient to improve the user's concentration, and improvements are required.
　本開示は、上記の事情に鑑みてなされたものであり、ユーザの集中度の低下をより高い精度で判定して、より集中しやすい環境を提供することが可能な空調制御を行う空気調和システム、空気調和装置、制御方法及びプログラムを提供することを目的とする。 The present disclosure has been made in consideration of the above circumstances, and aims to provide an air conditioning system, air conditioning device, control method, and program that performs air conditioning control that can determine a decrease in a user's concentration level with greater accuracy and provide an environment that makes it easier to concentrate.
　上記の目的を達成するため、本開示に係る空気調和システムは、空調対象空間の空調制御を行う空気調和システムであって、空調部と、制御装置とを備える。空調部は、空調対象空間を空調する。制御装置は、空調部を制御する。制御装置は、指標値取得手段と、制御手段とを有する。指標値取得手段は、空調対象空間に存在するユーザの体表面の動きの変化から求めた集中度を取得する。制御手段は、取得した集中度に基づいて、ユーザの集中度を増大させるように空調部を制御する。 In order to achieve the above object, the air conditioning system according to the present disclosure is an air conditioning system that controls the air conditioning of a space to be air-conditioned, and includes an air conditioning unit and a control unit. The air conditioning unit conditions the space to be air-conditioned. The control unit controls the air conditioning unit. The control unit has an index value acquisition means and a control means. The index value acquisition means acquires a concentration level determined from changes in the movement of the body surface of a user present in the space to be air-conditioned. The control means controls the air conditioning unit based on the acquired concentration level so as to increase the user's concentration level.
　本開示によれば、空気調和システムにおいて、体表面の動きの変化から求めた集中度を取得し、集中度を増大させるように空調制御を行うことができる。このため、ユーザの集中度を高精度で判定し、ユーザが集中しやすい環境を提供できる。 According to the present disclosure, in an air conditioning system, the degree of concentration can be obtained from changes in body surface movement, and air conditioning control can be performed to increase the degree of concentration. This makes it possible to determine the user's degree of concentration with high accuracy, and provide an environment in which the user can easily concentrate.

［空気調和システム１の構成］
　本開示の実施の形態１に係る空気調和システム１は、空調対象空間である室内空間７１に存在するユーザＨＭの集中度ＣＲに基づいて、室内空間７１を空調するシステムである。空調とは、空調空間の空気の温度、湿度、清浄度、気流等を調整することであって、具体的には、暖房、冷房、除湿、加湿、空気清浄等である。集中とは、一つの事柄に意識を集中して物事に取り組むことを意味する。集中度ＣＲとは、集中の度合いを意味する。人は作業を継続していると、その人の集中度ＣＲは次第に低下していく傾向にある。また、人は、集中度ＣＲが低下していくと、眠気を生じる傾向にある。逆もまた然りで、人は、眠気を生じると集中度ＣＲが低下する。いずれにしても、集中度ＣＲと、眠気の度合いを示す眠気度とは、密接な関係である。集中度ＣＲは、集中している程度を示す指標であり、本明細書では、集中度ＣＲが高い又は大きい程、集中の程度が高く、眠気度の低い状態にあるものとする。 (Embodiment 1)
[Configuration of Air Conditioning System 1]
The air conditioning system 1 according to the first embodiment of the present disclosure is a system that conditions an indoor space 71 based on the concentration level CR of a user HM present in the indoor space 71, which is an air-conditioned space. Air conditioning refers to adjusting the temperature, humidity, cleanliness, airflow, etc. of the air in the air-conditioned space, and specifically includes heating, cooling, dehumidification, humidification, air purification, etc. Concentration means concentrating one's mind on one thing and working on it. The concentration level CR means the degree of concentration. When a person continues working, the concentration level CR of the person tends to gradually decrease. In addition, when the concentration level CR decreases, a person tends to become sleepy. The opposite is also true, and when a person becomes sleepy, the concentration level CR decreases. In any case, the concentration level CR and the sleepiness level indicating the degree of sleepiness are closely related. The concentration level CR is an index indicating the degree of concentration, and in this specification, the higher or larger the concentration level CR, the higher the degree of concentration and the lower the sleepiness level.
　空気調和システム１は、図１に示すように、室内空間７１を空調する設備である空気調和装置２と、ユーザＨＭによって操作される情報機器９０を備えている。空調運転に際し、室内空間７１に存在するユーザＨＭの集中度ＣＲを向上させる空調制御が行われる。情報機器９０と、空気調和装置２に備えられた室内機制御部５３とは、ネットワークＮＷを介して接続されている。 As shown in FIG. 1, the air conditioning system 1 includes an air conditioner 2, which is equipment for conditioning an indoor space 71, and an information device 90 operated by a user HM. During air conditioning operation, air conditioning control is performed to improve the concentration level CR of the user HM present in the indoor space 71. The information device 90 and the indoor unit control unit 53 provided in the air conditioner 2 are connected via a network NW.
　図１に示すように、空気調和装置２は、家屋３に設置される。家屋３は、一例として、いわゆる一般的な戸建て住宅の建物である。空気調和装置２は、例えばＣＯ２（二酸化炭素）又はＨＦＣ（ハイドロフルオロカーボン）等を冷媒として用いたヒートポンプ式の空気調和設備である。 1, an air conditioner 2 is installed in a house 3. The house 3 is, for example, a typical detached residential building.

Hereinafter, the mechanisms that control the air direction, such as the vane and louvers, will be collectively referred to as the vane 34. The air conditioning device 2 has a refrigerant circuit that is configured by connecting the compressor 21, four-way valve 22, outdoor heat exchanger 23, expansion valve 24, and indoor heat exchanger 25 by the refrigerant piping 61. The refrigerant circuit circulates the refrigerant to perform the refrigeration cycle operation.
　圧縮機２１は、冷媒を圧縮して冷媒配管６１を循環させる。具体的に説明すると、圧縮機２１は、低温且つ低圧の冷媒を圧縮し、高圧及び高温となった冷媒を四方弁２２に吐出する。圧縮機２１は、駆動周波数に応じて運転容量を変化させることができるインバータ回路を備える。運転容量とは、圧縮機２１が単位時間当たりに冷媒を送り出す量である。圧縮機２１は、室外機制御部５１からの指示に従って運転容量を変更する。 The compressor 21 compresses the refrigerant and circulates it through the refrigerant piping 61. Specifically, the compressor 21 compresses low-temperature, low-pressure refrigerant and discharges the high-pressure, high-temperature refrigerant to the four-way valve 22. The compressor 21 is equipped with an inverter circuit that can change the operating capacity according to the drive frequency. The operating capacity is the amount of refrigerant that the compressor 21 sends out per unit time. The compressor 21 changes the operating capacity according to instructions from the outdoor unit control unit 51.
　四方弁２２は、圧縮機２１の吐出側に設置されている。四方弁２２は、空気調和装置２の運転が冷房又は除湿運転であるか暖房運転であるかに応じて、冷媒配管６１中の冷媒の流れる方向を切り替える。 The four-way valve 22 is installed on the discharge side of the compressor 21. The four-way valve 22 switches the direction of the refrigerant flow in the refrigerant piping 61 depending on whether the air conditioner 2 is operating in cooling or dehumidification mode, or in heating mode.
　室外熱交換器２３は、冷媒配管６１を流れる冷媒と、空調対象空間の外部である室外空間７２の空気、言い換えると外部空間の空気と、の間で熱交換を行う。室外送風機３１は、室外熱交換器２３の傍に設けられており、室外空間７２の空気を室外熱交換器２３に送る。室外送風機３１は室外空間７２の空気を吸い込む。吸い込まれた空気は、室外熱交換器２３に供給され、冷媒配管６１を流れる冷媒との間で熱交換された後、室外空間７２に吹き出される。 The outdoor heat exchanger 23 exchanges heat between the refrigerant flowing through the refrigerant piping 61 and the air in the outdoor space 72, which is outside the space to be air-conditioned, in other words, the air in the external space. The outdoor blower 31 is provided next to the outdoor heat exchanger 23 and sends the air in the outdoor space 72 to the outdoor heat exchanger 23. The outdoor blower 31 draws in air from the outdoor space 72. The drawn-in air is supplied to the outdoor heat exchanger 23, where it exchanges heat with the refrigerant flowing through the refrigerant piping 61, and is then blown out into the outdoor space 72.

The indoor blower 33 draws in the air in the indoor space 71. The drawn-in air is supplied to the indoor heat exchanger 25 and exchanges heat with the refrigerant piping 61, and then the air direction is adjusted by the vane 34 and the air is blown out as conditioned air into the indoor space 71. This conditions the indoor space 71. The indoor heat exchanger 25 has a humidifying function and a dehumidifying function. The humidifying method may be evaporation humidification, or steam humidification such as primary steam spray type, secondary steam spray type, or power-utilizing steam generation type, and any known method can be used. The dehumidifying method may be weak cooling dehumidification, reheat dehumidification, or any known method can be used.
　以下、室内空間７１を空調する部分のうち、室外機１１に配置されている圧縮機２１、四方弁２２、室外熱交換器２３、膨張弁２４、及び室外送風機３１を室外機空調部８１、室内機１３に配置されている室内熱交換器２５、室内送風機３３、及びベーン３４を室内機空調部８２と呼ぶ。また、室外機空調部８１と室内機空調部８２とを合わせて空調を行う部分として空調部８０と呼ぶ。 Hereinafter, among the parts that condition the indoor space 71, the compressor 21, four-way valve 22, outdoor heat exchanger 23, expansion valve 24, and outdoor blower 31 arranged in the outdoor unit 11 will be referred to as the outdoor unit air conditioning section 81, and the indoor heat exchanger 25, indoor blower 33, and vane 34 arranged in the indoor unit 13 will be referred to as the indoor unit air conditioning section 82. In addition, the outdoor unit air conditioning section 81 and the indoor unit air conditioning section 82 will be collectively referred to as the air conditioning section 80 as the part that performs air conditioning.
　室内機１３は、温度を検知する温度センサ４１と、湿度を検知する湿度センサ４２と、人、物等の対象から放射される赤外線を検知する赤外線センサ４４と、ユーザＨＭの集中度ＣＲを特定する生体情報検出装置４３と、を更に備えている。 The indoor unit 13 further includes a temperature sensor 41 that detects temperature, a humidity sensor 42 that detects humidity, an infrared sensor 44 that detects infrared rays emitted from people, objects, etc., and a biometric information detection device 43 that identifies the concentration level CR of the user HM.
　温度センサ４１は、測温抵抗体、サーミスタ、熱電対等を備え、室内空間７１の空気温度である室温を検知する。湿度センサ４２は、電気抵抗式、静電容量式等のセンサであり、室内空間７１の空気湿度である室内湿度を検知する。温度センサ４１及び湿度センサ４２は、室内熱交換器２５の吸い込み口に設置されており、室内送風機３３により室内熱交換器２５に吸い込まれる空気の温度及び湿度を検知する。室内熱交換器２５の吸い込み口に設置されていることで、温度センサ４１及び湿度センサ４２は、室内空間７１内の空気の温度及び湿度を精度良く検知することができる。 The temperature sensor 41 is equipped with a resistance temperature detector, thermistor, thermocouple, etc., and detects the room temperature, which is the air temperature in the indoor space 71. The humidity sensor 42 is an electrical resistance type, capacitance type, etc. sensor, and detects the indoor humidity, which is the air humidity in the indoor space 71. The temperature sensor 41 and humidity sensor 42 are installed at the intake port of the indoor heat exchanger 25, and detect the temperature and humidity of the air sucked into the indoor heat exchanger 25 by the indoor blower 33. By being installed at the intake port of the indoor heat exchanger 25, the temperature sensor 41 and humidity sensor 42 can accurately detect the temperature and humidity of the air in the indoor space 71.
　赤外線センサ４４は、焦電型、サーモパイル型等のセンサであり、人、物等の対象から放射される赤外線を検知する。赤外線センサ４４は、室内空間７１に存在する人、物等の対象から放射される赤外線を検知することにより、人、物等の対象の存在及び位置を特定することができる。赤外線センサ４４は、指向性を有し、ジンバル機構等により、指向方向を制御可能に構成されている。 The infrared sensor 44 is a pyroelectric, thermopile, or other type of sensor, and detects infrared rays emitted from objects such as people and objects. The infrared sensor 44 can identify the presence and position of objects such as people and objects by detecting infrared rays emitted from objects such as people and objects present in the indoor space 71. The infrared sensor 44 is directional, and is configured so that the direction of direction can be controlled by a gimbal mechanism, etc.
　生体情報検出装置４３は、生体情報を検出して集中度ＣＲを特定する。生体情報検出装置４３は、図示しないドップラーセンサを含む。ドップラーセンサは、指向性を有し、ジンバル機構等により指向方向を制御可能である。ドップラーセンサは、マイクロ波帯または準ミリ波帯と呼ばれるおよそ２４ＧＨｚの正弦波の電波を、赤外線センサ４４によって検知された人体に向けて照射する。ドップラーセンサは、人体からの反射波を受信し、人体の体表面の動きの変化、すなわち、人体の脈波を検出する。脈波とは、心臓の脈動による人の体表面の動きの変化を示す波形であり、血管の動きの変化の波形と、心臓部分の体表面の変化の波形を含む。生体情報検出装置４３は、ドップラーセンサで検出された脈波を解析し、集中度ＣＲを特定する。生体情報検出装置４３は、脈波を周期的に解析し、集中度ＣＲを周期的に特定する。脈波から集中度ＣＲを導出する手法は、既知の任意の手法を使用可能である。例えば、脈波の時系列データから、心拍変動の時系列データを求め、これを周波数解析して、呼吸変動に対応する高周波変動成分（ＨＦ成分）と血圧変動であるメイヤー波（Mayer wave）に対応する低周波成分（ＬＦ成分）を抽出し、トータルパワー（＝ＨＦ＋ＬＦ）との比率（＝ＬＦ／（ＨＦ＋ＬＦ））を数値化することにより、集中度ＣＲを求めることができる。また、交感神経が優位にある場合にＬＦ成分が現れるため、ＬＦ成分の数値を交感神経の活性度、即ち、集中度ＣＲとしてもよい。 The bioinformation detection device 43 detects the bioinformation and determines the concentration level CR. The bioinformation detection device 43 includes a Doppler sensor (not shown). The Doppler sensor has directionality and the direction of direction can be controlled by a gimbal mechanism or the like. The Doppler sensor irradiates a sine wave radio wave of about 24 GHz, called the microwave band or the quasi-millimeter wave band, toward the human body detected by the infrared sensor 44. The Doppler sensor receives the reflected wave from the human body and detects the change in the movement of the body surface of the human body, that is, the human body's pulse wave. The pulse wave is a waveform that indicates the change in the movement of the human body surface due to the pulsation of the heart, and includes a waveform of the change in the movement of the blood vessels and a waveform of the change in the body surface of the heart. The bioinformation detection device 43 analyzes the pulse wave detected by the Doppler sensor and determines the concentration level CR. The bioinformation detection device 43 periodically analyzes the pulse wave and periodically determines the concentration level CR. Any known method can be used to derive the concentration level CR from the pulse wave. For example, time series data of heart rate fluctuations can be obtained from time series data of pulse waves, and this can be frequency analyzed to extract high frequency fluctuation components (HF components) corresponding to respiratory fluctuations and low frequency components (LF components) corresponding to Mayer waves, which are blood pressure fluctuations, and the concentration level CR can be calculated by quantifying the ratio (= LF/(HF + LF)) to the total power (= HF + LF). Also, since the LF component appears when the sympathetic nervous system is dominant, the numerical value of the LF component can be used as the activity level of the sympathetic nervous system, i.e., the concentration level CR.
　また、脈波から脈拍を抽出し、脈拍の変化を利用して、脳の覚醒度合いを求め、求めた覚醒度合いから集中度ＣＲを推定することも可能である。例えば、脈拍の変化が大きければ覚醒度合いが大きく、集中度ＣＲが高い状態である。一方、脈拍の変化が小さければ覚醒度合いが小さく眠気に襲われている状態であり、集中度ＣＲが低い状態である。 It is also possible to extract the pulse rate from the pulse wave, use the changes in the pulse rate to determine the brain's level of alertness, and estimate the concentration level CR from the determined level of alertness. For example, a large change in the pulse rate indicates a high level of alertness and a high level of concentration CR. On the other hand, a small change in the pulse rate indicates a low level of alertness, a drowsy state, and a low level of concentration CR.
　体温は、寝ているときも起きている時も大きな変化がある。また、体温は、午前中に変化率が高く、午後は変化率が低い傾向がある。このため、体温変化率に基づいて集中度ＣＲを判断することは精度が低く信頼性に欠ける。これに対し、脈波には、このような問題はなく、より高い精度で集中度ＣＲを求めることができる。 Body temperature changes greatly whether you are asleep or awake. Also, body temperature tends to change more rapidly in the morning and less rapidly in the afternoon. For this reason, judging concentration level CR based on the rate of change of body temperature is inaccurate and unreliable. In contrast, pulse waves do not have these problems and can determine concentration level CR with greater accuracy.
　以下、温度センサ４１と湿度センサ４２と赤外線センサ４４と生体情報検出装置４３とを総称して、センサ群４０と呼ぶ。それらの出力を総称してセンサ群４０の出力群と呼ぶ。センサ群４０の出力は、室内機制御部５３に供給される。 Hereinafter, the temperature sensor 41, humidity sensor 42, infrared sensor 44, and biological information detection device 43 are collectively referred to as the sensor group 40.

Specifically, the storage unit 53b stores general air conditioning control programs such as cooling control, heating control, and dehumidification control, and also stores a control program for causing the control unit 53a to execute air conditioning control to improve the concentration level CR of the user HM in the indoor space 71, that is, a control program for concentration mode (hereinafter, simply referred to as control program) 54. Here, "concentration mode" refers to an operation mode in which air conditioning control is performed to improve the concentration level CR of the user HM. The control program 54 functionally includes an acquisition processing unit 54a that causes the control unit 53a to execute a process to acquire the concentration level CR, a determination processing unit 54b that causes the control unit 53a to execute a determination process including a process to determine whether the acquired concentration level CR has decreased and the absolute value of the difference is equal to or greater than the determination threshold value Tha, a control processing unit 54c that causes the control unit 53a to execute air conditioning processing in the concentration mode, and a set value group 54d.
　設定値群５４ｄは、図４に示すように、集中度ＣＲの低下の程度、または上昇の程度を判定するための基準値である判定閾値Ｔｈａ,Ｔｈｂ、集中モードでの暖房時の制御対象と制御内容、冷蔵時の制御対象と制御内容、移行期間を記憶している。図４では、例えば、集中モードの暖房運転では、室温を設定値にかかわらず目標温度ＴＨｏまで下降させ、湿度を設定値にかかわらず目標湿度ＨＨｏまで上昇させ、風量を設定値にかかわらず目標風量ＦＨｏまで上昇させ、風あて制御することが設定されている。また、移行期間は、集中モードが設定されてから、各制御対象が目標値に移行するまでの設定期間であり、図４では、Ｐｓに設定されている。図４では、４つの制御対象に共通の移行期間Ｐｓが設定されているが、制御対象毎に移行期間が個別に設定されてもよい。記憶部５３ｂは、取得した集中度ＣＲを時刻情報とともに保存する。なお、記憶部５３ｂは、初期設定の集中度ＣＲとして、入学試験、検定試験、競技大会など、集中力が高い時に示す値を保存している。 As shown in FIG. 4, the set value group 54d stores the judgment thresholds Tha and Thb, which are reference values for judging the degree of decrease or increase of the concentration level CR, the control target and control content during heating in the concentration mode, the control target and control content during refrigeration, and the transition period. In FIG. 4, for example, in the heating operation in the concentration mode, the room temperature is lowered to the target temperature THo regardless of the set value, the humidity is raised to the target humidity HHo regardless of the set value, and the air volume is raised to the target air volume FHo regardless of the set value, and the air blowing control is performed. The transition period is the set period from when the concentration mode is set until each control target transitions to the target value, and is set to Ps in FIG. 4. In FIG. 4, a common transition period Ps is set for the four control targets, but the transition period may be set individually for each control target. The memory unit 53b stores the acquired concentration level CR together with time information. The memory unit 53b stores the initial concentration level CR as a value that is shown when concentration is high, such as during entrance exams, qualification exams, and competitions.
　図３に示す計時部５３ｃは、時間を計る部分である。計時部５３ｃは、ＲＴＣを備えており、空気調和装置２の電源がオフの間も計時を継続する計時デバイスである。 The timer unit 53c shown in FIG. 3 is a unit that measures time. The timer unit 53c is equipped with an RTC and is a timing device that continues to measure time even when the power to the air conditioning device 2 is off.
　通信部５３ｄは、室外機制御部５１と通信し、また、情報機器９０とネットワークＮＷを介して通信する。 The communication unit 53d communicates with the outdoor unit control unit 51 and also communicates with the information device 90 via the network NW.
　次に、室外機制御部５１と室内機制御部５３のハードウェア構成の一例について、図５（Ａ）、（Ｂ）を参照しながら説明する。 Next, an example of the hardware configuration of the outdoor unit control unit 51 and the indoor unit control unit 53 will be described with reference to Figures 5 (A) and (B).
　室外機制御部５１は、マイクロコントローラ等のコンピュータから構成され、例えば、図５（Ａ）に示すように、バス１０００を介して互いに接続された、制御プログラムを実行するプロセッサ１００１と、主記憶領域として機能するメモリ１００２と、制御プログラムを記憶する二次記憶装置１００３と、信号を入出力する入出力（Ｉ／Ｏ）インタフェース１００４と、通信を行う通信モジュール１００５と、を備える。 The outdoor unit control unit 51 is composed of a computer such as a microcontroller, and includes, for example, a processor 1001 that executes a control program, a memory 1002 that functions as a main memory area, a secondary storage device 1003 that stores the control program, an input/output (I/O) interface 1004 that inputs and outputs signals, and a communication module 1005 that performs communication, all of which are connected to each other via a bus 1000, as shown in FIG. 5(A).
　プロセッサ１００１は、例えばＣＰＵ（Central Processing Unit：中央算出装置）である。プロセッサ１００１が、二次記憶装置１００３に記憶された制御プログラムをメモリ１００２に読み込んで実行する。 The processor 1001 is, for example, a CPU (Central Processing Unit). The processor 1001 loads a control program stored in the secondary storage device 1003 into the memory 1002 and executes it.
　メモリ１００２は、例えば、ＲＡＭにより構成される主記憶装置である。メモリ１００２は、プロセッサ１００１のワークメモリとして機能し、プロセッサ１００１が二次記憶装置１００３から読み込んだ制御プログラムを記憶する。 Memory 1002 is, for example, a main storage device configured from a RAM. Memory 1002 functions as a work memory for processor 1001, and stores the control program that processor 1001 reads from secondary storage device 1003.
　二次記憶装置１００３は、フラッシュメモリ、ＨＤＤ（Hard Disk Drive）、ＳＳＤ（Solid State Drive）等から構成される。二次記憶装置１００３は、プロセッサ１００１が実行する制御プログラム、固定データ等を記憶する。 The secondary storage device 1003 is composed of a flash memory, a hard disk drive (HDD), a solid state drive (SSD), etc. The secondary storage device 1003 stores the control program executed by the processor 1001, fixed data, etc.
　Ｉ／Ｏ（Input/Output）インタフェース１００４は、シリアルポート、ＵＳＢ（Universal Serial Bus）ポートインタフェース等から構成される。Ｉ／Ｏインタフェース１００４は、室外機１１内の室外機空調部８１、例えば、圧縮機２１、四方弁２２、膨張弁２４、室外送風機３１等に制御信号を送信して、プロセッサ１００１による制御を可能とする。 The I/O (Input/Output) interface 1004 is composed of a serial port, a USB (Universal Serial Bus) port interface, etc. The I/O interface 1004 transmits control signals to the outdoor unit air conditioning section 81 in the outdoor unit 11, such as the compressor 21, the four-way valve 22, the expansion valve 24, the outdoor blower 31, etc., enabling control by the processor 1001.
　通信モジュール１００５は、ネットワークインタフェース等から構成され、プロセッサ１００１と室内機制御部５３との間の通信を実現する。 The communication module 1005 is composed of a network interface, etc., and realizes communication between the processor 1001 and the indoor unit control unit 53.
　制御部５１ａと計時部５１ｃとは、例えば、プロセッサ１００１とＩ／Ｏインタフェース１００４とから構成される。また、記憶部５１ｂは、メモリ１００２と二次記憶装置１００３から構成される。また、通信部５１ｄは、例えば、通信モジュール１００５から構成される。 The control unit 51a and the timer unit 51c are each composed of, for example, a processor 1001 and an I/O interface 1004. The storage unit 51b is composed of a memory 1002 and a secondary storage device 1003. The communication unit 51d is composed of, for example, a communication module 1005.
　一方、室内機制御部５３は、マイクロコントローラ等のコンピュータから構成され、例えば、図５（Ｂ）に示すように、バス１０１０を介して互いに接続された、制御プログラムを実行するプロセッサ１０１１と、主記憶領域として機能するメモリ１０１２と、制御プログラムを記憶する二次記憶装置１０１３と、信号を入出力するＩ／Ｏインタフェース１０１４と、通信を行う通信モジュール１０１５と、を備える。プロセッサ１０１１と、メモリ１０１２と、二次記憶装置１０１３と、Ｉ／Ｏインタフェース１０１４と、通信モジュール１０１５とは、図５（Ａ）に示す室外機制御部５１を構成するバス１０００と、プロセッサ１００１と、メモリ１００２と、二次記憶装置１００３と、Ｉ／Ｏインタフェース１００４と、通信モジュール１００５と、同一の構成と機能を備える。ただし、二次記憶装置１０１３は、集中モード用制御プログラム５４を記憶し、Ｉ／Ｏインタフェース１０１４は、センサ群４０、リモコン５５、本体表示部５８と室内機空調部８２、例えばベーン３４の駆動機構に接続されている。また、通信モジュール１０１５は、室外機制御部５１とネットワークＮＷに接続されている。 On the other hand, the indoor unit control unit 53 is composed of a computer such as a microcontroller, and includes, for example, a processor 1011 that executes a control program, a memory 1012 that functions as a main memory area, a secondary storage device 1013 that stores the control program, an I/O interface 1014 that inputs and outputs signals, and a communication module 1015 that performs communication, all of which are connected to one another via a bus 1010, as shown in Fig. 5(B). The processor 1011, memory 1012, secondary storage device 1013, I/O interface 1014, and communication module 1015 have the same configurations and functions as the bus 1000, processor 1001, memory 1002, secondary storage device 1003, I/O interface 1004, and communication module 1005 that constitute the outdoor unit control unit 51 shown in Fig. 5(A). However, the secondary storage device 1013 stores the control program 54 for the concentrated mode, and the I/O interface 1014 is connected to the sensor group 40, the remote control 55, the main body display unit 58, and the indoor unit air conditioning unit 82, for example, the drive mechanism of the vane 34. In addition, the communication module 1015 is connected to the outdoor unit control unit 51 and the network NW.
　ここまで、空気調和システム１の構成について説明した。続いて、その動作について説明する。
　空気調和装置２は、通常時は、一般的な通常モードでの空調運転を行っているが、集中モードによる空調運転に切り替わると、ユーザＨＭの集中度ＣＲを向上させるような、例えば予め設定されているような集中度向上制御処理を実行する。以下、理解を容易にするため、図２に例示した使用環境で、空気調和装置２が実行する集中度向上制御処理を説明する。 Up to this point, a description has been given of the configuration of the air conditioning system 1. Next, a description will be given of its operation.
The air conditioning device 2 normally performs air conditioning operation in a general normal mode, but when it switches to air conditioning operation in the concentration mode, it executes, for example, a preset concentration improvement control process that improves the concentration level CR of the user HM. For ease of understanding, the concentration improvement control process executed by the air conditioning device 2 in the usage environment exemplified in Fig. 2 will be described below.
　ユーザＨＭが、パソコンでの作業、書物を読む作業など各種の作業を継続して行い、集中力の低下を感じ始めたとき等に、リモコン５５を用いて「集中モード」を選択する。すると、その選択が制御部５３ａに判別され、制御部５３ａは、集中モード用制御プログラム５４の実行を開始する。制御部５３ａは、まず、赤外線センサ４４によりユーザＨＭの存在を特定し、生体情報検出装置４３に対して、ユーザＨＭの集中度ＣＲを取得するために指示を送る。 When user HM continues to perform various tasks such as working on a computer or reading a book and begins to feel a decline in his/her concentration, he/she selects "concentration mode" using remote control 55. This selection is then recognized by control unit 53a, which starts executing control program 54 for concentration mode. First, control unit 53a identifies the presence of user HM using infrared sensor 44, and sends an instruction to biometric information detection device 43 to obtain the concentration level CR of user HM.
　また、制御部５３ａは、図６に示す集中度向上制御処理を開始する。
　まず、制御部５３ａは、生体情報検出装置４３からユーザＨＭの集中度ＣＲを取得し記憶する（ステップＳ１０１）。制御部５３ａは、前回取得した集中度ＣＲt-1と、今回取得した集中度ＣＲtとの差分ＣＢｔ（＝ＣＲt－ＣＲt-1）が負の値であり、且つ、差分ＣＢｔの絶対値が判定閾値Ｔｈａ以上であるか否かを判定する（ステップＳ１０２）。上述したように、記憶部５３ｂは、初期設定の集中度ＣＲt-1として、集中力が高い時に示す値を保存している。このため、制御部５３ａは、初回には、前回取得した集中度ＣＲt-1を、初期設定の集中度ＣＲとして、ステップＳ１０２の処理を行う。 Furthermore, the control unit 53a starts the concentration improvement control process shown in FIG.
First, the control unit 53a acquires and stores the concentration level CR of the user HM from the bioinformation detection device 43 (step S101). The control unit 53a judges whether the difference CB t (=CR t -CR t-1 ) between the previously acquired concentration level CR t-1 and the currently acquired concentration level CR t is a negative value and whether the absolute value of the difference CB t is equal to or greater than the judgment threshold value Tha (step S102). As described above, the storage unit 53b stores a value that indicates a high level of concentration as the initial concentration level CR t-1 . For this reason, the control unit 53a performs the process of step S102 for the first time by setting the previously acquired concentration level CR t-1 as the initial concentration level CR.
　ユーザＨＭは、集中力の低下を感じ始めて「集中モード」を選択しているので、初回は、集中度ＣＲは低下し、且つ、差分ＣＢｔの絶対値は判定閾値Ｔｈａ以上である（ステップＳ１０２：Ｙｅｓ）と想定する。制御部５３ａは、集中度ＣＲは低下し、且つ、差分ＣＢｔの絶対値は判定閾値Ｔｈａ以上であると判定した場合（ステップＳ１０２：Ｙｅｓ）、集中度向上運転を実行する（ステップＳ１０３）。集中度向上運転は、ユーザＨＭの集中度ＣＲを増大させるために行う運転を意味する。なお、制御部５３ａは、計時部５３ｃに基づいて、集中度向上運転の実行開始時刻を、記憶部５３ｂに保存する。 Since the user HM has started to feel a decrease in concentration and has selected the "concentration mode", it is assumed that the concentration level CR has decreased and the absolute value of the difference CB t is equal to or greater than the judgment threshold Tha (step S102: Yes) for the first time. When the control unit 53a determines that the concentration level CR has decreased and the absolute value of the difference CB t is equal to or greater than the judgment threshold Tha (step S102: Yes), it executes a concentration level improvement operation (step S103). The concentration level improvement operation refers to an operation performed to increase the concentration level CR of the user HM. The control unit 53a stores the start time of the execution of the concentration level improvement operation in the memory unit 53b based on the timer unit 53c.
　集中度向上運転では、ユーザＨＭの設定と離れて、冷房の場合、図４に例示するように、例えば、移行期間Ｐｓの間に室温を目標温度ＴＣｏまで下げ、湿度を移行期間Ｐｓの間に目標湿度ＨＣｏまで下げ、移行期間Ｐｓの間に風量を目標風量ＦＣｏまで増大させ、風向きを風あて制御にし、暖房の場合、室温を目標温度ＴＨｏまで下げ、湿度を目標湿度ＨＨｏまで上げ、風量を目標風量ＦＨｏまで増大させ、風向きを風あて制御にする。なお、風あて制御は、図７（Ａ）に模式的に示すように、ユーザＨＭに室内機１３からの送風が空中を流れて直接当たるように風向を制御する方法である。風あて制御は、送風が床、壁などに当たってからユーザＨＭまで届く態様の送風を含まない。また、ユーザＨＭの足下に風を当てる例に限定されず、生体情報検出装置４３と赤外線センサ４４によりユーザＨＭの体の部位を特定し、予め設定された部位、例えば、腰、胸、顔、頭等に風が当たるように、風向を制御してもよい。なお、ユーザＨＭの体の部位を判別する必要がある場合には、例えば、センサ群４０に画像センサを追加し、画像解析から部位を求めるようにしてもよい。 In the concentration improvement operation, apart from the settings of the user HM, in the case of cooling, as illustrated in FIG. 4, for example, the room temperature is lowered to the target temperature TCo during the transition period Ps, the humidity is lowered to the target humidity HCo during the transition period Ps, the air volume is increased to the target air volume FCo during the transition period Ps, and the air direction is set to air blowing control, while in the case of heating, the room temperature is lowered to the target temperature THo, the humidity is raised to the target humidity HHo, the air volume is increased to the target air volume FHo, and the air direction is set to air blowing control. Note that air blowing control is a method of controlling the air direction so that the air blown from the indoor unit 13 flows through the air and hits the user HM directly, as shown diagrammatically in FIG. 7(A). Air blowing control does not include air blowing in a manner in which the air hits the floor, wall, etc. before reaching the user HM. Furthermore, the example is not limited to blowing wind on the feet of the user HM, but the body part of the user HM may be identified using the biometric information detection device 43 and the infrared sensor 44, and the wind direction may be controlled so that the wind blows on a preset part, such as the waist, chest, face, head, etc. If it is necessary to determine the body part of the user HM, for example, an image sensor may be added to the sensor group 40, and the part may be determined from image analysis.
　集中度向上運転のため、制御部５３ａは、その時点の室温ＴＲ、湿度ＨＲ、風量ＦＲ、風向きを特定する。
　次に、制御部５３ａは、暖房の場合、現在の室温ＴＲと予め設定されている集中度向上制御での目標室温ＴＨｏとの温度差ＤＴ、現在の湿度ＨＲと予め設定されている集中度向上制御での目標湿度ＨＨｏとの湿度差ＤＨ、現在の風量ＦＲと予め設定されている集中度向上制御での目標風量ＦＨｏとの風量差ＤＦを特定する。さらに、制御部５３ａは、図７（Ａ）、（Ｂ）に例示するように、ユーザＨＭの位置と送風が床に当たる現在の位置とを特定し、両者の距離ＤＬを求め、風向きを示すデータとする。なお、風向きを示すデータとして、送風の鉛直方向からの傾斜角などを採用してもよい。 For the concentration improvement operation, the control unit 53a identifies the room temperature TR, humidity HR, air volume FR, and air direction at that time.
Next, in the case of heating, the control unit 53a specifies the temperature difference DT between the current room temperature TR and the target room temperature THo in the preset concentration improvement control, the humidity difference DH between the current humidity HR and the target humidity HHo in the preset concentration improvement control, and the air volume difference DF between the current air volume FR and the target air volume FHo in the preset concentration improvement control. Furthermore, as shown in Fig. 7 (A) and (B), the control unit 53a specifies the position of the user HM and the current position where the blown air hits the floor, calculates the distance DL between them, and sets it as data indicating the wind direction. Note that the data indicating the wind direction may be the inclination angle of the blown air from the vertical direction, or the like.
　次に、求めた温度差ＤＴ、湿度差ＤＨ、風量差ＤＦ、距離ＤＬを予め設定されている移行期間Ｐsで除算し、単位時間あたりの変更量を求める。例えば、暖房運転状態で、現在の室温がＴＲ℃、予め設定されている目標室温がＴＨｏ℃、移行期間をＰs［ｍ］とすると、単位時間あたりの温度の変化量ΔＴは（ＴＲ－ＴＨｏ）／Ｐs［℃／ｍ」と求められる。同様に、図７（Ａ）、（Ｂ）に模式的に示すように現在の送風が床に当たる位置とユーザＨＭの位置の距離をＤＬ［ｍ］とすると、暖房運転でＤＬ＝０とするために、単位時間あたりの送風位置の移動量ΔＤＬはＤＬ［ｍ］／Ｐs［ｍ］と求められる。湿度の変化量ΔＨと風量の変化量ΔＦについても同様に求める。 Next, the calculated temperature difference DT, humidity difference DH, airflow difference DF, and distance DL are divided by the preset transition period Ps to determine the amount of change per unit time. For example, in heating operation, if the current room temperature is TR°C, the preset target room temperature is THo°C, and the transition period is Ps [m], the amount of change in temperature per unit time ΔT is calculated as (TR-THo)/Ps [°C/m]. Similarly, as shown in Figs. 7(A) and (B) diagrammatically, if the distance between the position where the current airflow hits the floor and the position of the user HM is DL [m], the amount of movement ΔDL of the airflow position per unit time to make DL=0 in heating operation is calculated as DL [m]/Ps [m]. The amount of change in humidity ΔH and the amount of change in airflow ΔF are calculated in the same manner.
　制御部５３ａは、動作モードが集中モードであること、暖房と冷房の別、目標温度、目標湿度、目標風量、目標風向、単位変化量ΔＴ，ΔＨ，ΔＦ，ΔＤＬ、等の情報を含む制御指示信号を室外機制御部５１に通信部５３ｄを介して送信する。 The control unit 53a transmits a control instruction signal to the outdoor unit control unit 51 via the communication unit 53d, including information such as the fact that the operating mode is the concentrated mode, whether it is heating or cooling, the target temperature, the target humidity, the target air volume, the target air direction, the unit changes ΔT, ΔH, ΔF, ΔDL, etc.
　室外機制御部５１の制御部５１ａは、通信部５１ｄを介して制御部５３ａから送信された制御指示信号を受信し、温度、風量を、単位変化量ΔＴ，ΔＦで、目標温度ＴＨｏ又はＴＣo、目標風量ＦＨｏ又はＦＣｏまで変化させるように、計時部５１ｃの計時時間を参照しつつ、室外機空調部８１、すなわち、圧縮機２１の回転周波数、膨張弁２４の開度、室外送風機３１の送風量などを制御する。 The control unit 51a of the outdoor unit control unit 51 receives the control instruction signal sent from the control unit 53a via the communication unit 51d, and controls the outdoor unit air conditioning unit 81, i.e., the rotational frequency of the compressor 21, the opening of the expansion valve 24, the air volume of the outdoor blower 31, etc., while referring to the time measured by the timing unit 51c, so as to change the temperature and air volume to the target temperature THo or TCo and the target air volume FHo or FCo by unit changes ΔT and ΔF.
　同様に、室内機制御部５３の制御部５３ａは、温度、湿度、風量、送風を単位変化量ΔＴ，ΔＨ，ΔＦ、ΔＤＬで、目標温度ＴＨｏ又はＴＣo、目標湿度ＨＨｏ又はＨＣo、目標風量ＦＨｏ又はＦＣｏ、目標位置まで変化させるように、計時部５３ｃの計時時間を参照しつつ、室内機空調部８２，すなわち、室内送風機３３の熱交換量、送風量、調湿量、ベーン３４の向き等を制御する。 Similarly, the control unit 53a of the indoor unit control unit 53 controls the indoor unit air conditioning unit 82 (i.e., the heat exchange amount, airflow amount, humidity control amount, and vane 34 direction, etc.) of the indoor blower 33 while referring to the time measured by the timer unit 53c, so as to change the temperature, humidity, airflow amount, and airflow by unit changes ΔT, ΔH, ΔF, and ΔDL to the target temperature THo or TCo, target humidity HHo or HCo, target airflow FHo or FCo, and target position.
　なお、制御部５１ａと５３ａは、温度等の各制御対象が目標値に達した場合には、以後は、その目標値を維持するように制御する。 In addition, when each controlled object, such as temperature, reaches a target value, the control units 51a and 53a control the object to maintain that target value.
　図６に戻り、制御部５３ａは、ステップＳ１０１で取得した集中度ＣＲが、低下して且つ差分の絶対値は判定閾値Ｔｈａ以上ではないと判定した場合（ステップＳ１０２：Ｎｏ）、ユーザＨＭの集中度ＣＲが上昇、維持、または、低下の度合いが著しくはない状態のため、集中度向上運転を行わず、処理をステップＳ１０８へ進め、「集中モード」が停止されたか否かを判定する（ステップＳ１０８）。「集中モード」が停止されたと判定した場合（ステップＳ１０８：Ｙｅｓ）、制御部５３ａは、集中度向上制御処理を終了し、室外機制御部５１にも集中モード終了を示す制御指示信号を送信する。室外機制御部５１も停止の処理を行う。なお、通常モードの動作に復帰してもよい。「集中モード」の停止は、リモコン５５による「集中モード」の終了の指示が行われた場合と、空気調和装置２の運転停止の指示が行われた場合等を含む。 Returning to FIG. 6, if the control unit 53a determines that the concentration level CR acquired in step S101 has decreased and the absolute value of the difference is not equal to or greater than the judgment threshold value Tha (step S102: No), the concentration level CR of the user HM is not increasing, being maintained, or decreasing significantly, so the control unit 53a does not perform the concentration level improvement operation and proceeds to step S108 to determine whether the "concentration mode" has been stopped (step S108). If the control unit 53a determines that the "concentration mode" has been stopped (step S108: Yes), the control unit 53a ends the concentration level improvement control process and also transmits a control instruction signal to the outdoor unit control unit 51 indicating the end of the concentration mode. The outdoor unit control unit 51 also performs a stop process. The control unit 53a may return to normal mode operation. Stopping the "concentration mode" includes a case where an instruction to end the "concentration mode" is given by the remote control 55, a case where an instruction to stop the operation of the air conditioning device 2 is given, etc.
　一方、ステップＳ１０８で、「集中モード」が停止されていないと判定した場合（ステップＳ１０８：Ｎｏ）、処理はステップＳ１０１に戻る。 On the other hand, if it is determined in step S108 that the "concentration mode" has not been stopped (step S108: No), the process returns to step S101.
　ステップＳ１０３の集中度向上運転を一定期間継続すると、制御部５３ａは、記憶部５３ｂに保存された集中度向上運転実行開始時刻と、計時部５３ｃとに基づいて、集中度向上運転を予め定められた時間以上実施しているか否かを判定する（ステップＳ１０４）。本実施の形態において、予め定められた時間は３分である。なお、集中度向上運転の実行時間は３分に限らず５分であってもよく、本実施の形態の作用効果を奏するならば、任意の実行時間でもよい。 When the concentration improvement operation in step S103 continues for a certain period of time, the control unit 53a determines whether the concentration improvement operation has been performed for a predetermined time or longer based on the concentration improvement operation execution start time stored in the memory unit 53b and the timing unit 53c (step S104). In this embodiment, the predetermined time is three minutes. Note that the execution time of the concentration improvement operation is not limited to three minutes, but may be five minutes, or any execution time may be used as long as the effect of this embodiment is achieved.
　制御部５３ａは、集中度向上運転を予め定められた時間以上実施していないと判定した場合（ステップＳ１０４：Ｎｏ）、ステップＳ１０１と同様に、生体情報検出装置４３から集中度ＣＲを取得する（ステップＳ１０５）。制御部５３ａは、ステップＳ１０５で取得した集中度ＣＲが、予め定められた判定閾値Ｔｈｂ以上であるか否かを判定する（ステップＳ１０６）。制御部５３ａは、集中度ＣＲが判定閾値Ｔｈｂ以上ではないと判定した場合（ステップＳ１０６：Ｎｏ）、ユーザＨＭの集中度ＣＲは向上していない状態である。このため、制御部５３ａは、集中度向上運転を継続しながら、処理をステップＳ１０４へ戻す。 If the control unit 53a determines that the concentration improvement operation has not been performed for a predetermined time or longer (step S104: No), it acquires the concentration level CR from the bioinformation detection device 43, as in step S101 (step S105). The control unit 53a judges whether the concentration level CR acquired in step S105 is equal to or greater than a predetermined judgment threshold Thb (step S106). If the control unit 53a judges that the concentration level CR is not equal to or greater than the judgment threshold Thb (step S106: No), the concentration level CR of the user HM has not improved. Therefore, the control unit 53a returns the process to step S104 while continuing the concentration improvement operation.
　制御部５３ａは、集中度ＣＲが判定閾値Ｔｈｂ以上であると判定した場合（ステップＳ１０６：Ｙｅｓ）、ユーザＨＭの集中度ＣＲを向上させた状態に至っている。このため、制御部５３ａは、集中度向上運転を停止する（ステップＳ１０７）。制御部５３ａは、集中モードの停止（ステップＳ１０８：Ｙｅｓ）を経て、集中度向上制御処理を終了し、通常運転モードに復帰する。あるいは、空気調和装置２の動作を停止してもよい。なお、制御部５３ａは、ステップＳ１０８で集中モードは停止していないと判定した場合（ステップＳ１０８：Ｎｏ）、処理をステップＳ１０１へ戻す。 When the control unit 53a determines that the concentration level CR is equal to or greater than the judgment threshold Thb (step S106: Yes), the concentration level CR of the user HM has been improved. Therefore, the control unit 53a stops the concentration level improvement operation (step S107). After stopping the concentration mode (step S108: Yes), the control unit 53a ends the concentration level improvement control process and returns to the normal operation mode. Alternatively, the operation of the air conditioning device 2 may be stopped. Note that when the control unit 53a determines in step S108 that the concentration mode has not been stopped (step S108: No), the process returns to step S101.
　制御部５３ａは、集中度向上運転を予め定められた時間以上実施していると判定した場合（ステップＳ１０４：Ｙｅｓ）、集中度向上運転を停止する（ステップＳ１０７）。集中度向上運転は、通常の運転からの変化によって効果が発生し易い。このため、集中度向上運転を継続しても集中度ＣＲを向上させる効果は低くなる傾向にあることから、制御部５３ａは、予め定められた時間以上の実施で集中度向上運転を停止する。ステップＳ１０７以後の処理は、上記と同様である。 If the control unit 53a determines that the concentration improving driving has been performed for a predetermined time or longer (step S104: Yes), it stops the concentration improving driving (step S107). The effect of concentration improving driving is likely to be produced by a change from normal driving. For this reason, even if the concentration improving driving is continued, the effect of improving the concentration level CR tends to decrease, so the control unit 53a stops the concentration improving driving if it has been performed for a predetermined time or longer. The processing from step S107 onwards is the same as above.
　また、制御部５３ａは、ステップＳ１０６で集中度向上運転を実行している間、制御態様を示す情報を、室内機１３の本体表示部５８に表示する。具体的には、制御部５３ａは、図４に例示する集中モード用制御態様テーブルの運転モードと、制御対象と、制御内容を示す情報を、ユーザＨＭに報知する情報として、室内機１３の本体表示部５８に表示させる。制御部５３ａは、リモコン５５の表示部５５ａ、情報機器９０の表示部９０ａに集中モード用制御態様テーブルの運転モードと、制御対象と、制御内容を示す情報を、ユーザＨＭに報知する情報として表示するように、リモコン５５と情報機器９０に指示を送ってもよい。また、制御部５３ａは、集中度向上運転の際、制御態様を示す情報を、音声によって報知してもよい。例えば、制御部５３ａは、室内機１３に設けられたスピーカによって報知してもよい。 In addition, while the concentration improvement operation is being performed in step S106, the control unit 53a displays information indicating the control mode on the main body display unit 58 of the indoor unit 13. Specifically, the control unit 53a causes the main body display unit 58 of the indoor unit 13 to display information indicating the operation mode, the control target, and the control content in the control mode table for the concentration mode, as illustrated in FIG. 4, as information to be notified to the user HM. The control unit 53a may send an instruction to the remote control 55 and the information device 90 to display information indicating the operation mode, the control target, and the control content in the control mode table for the concentration mode on the display unit 55a of the remote control 55 and the display unit 90a of the information device 90 as information to be notified to the user HM. In addition, the control unit 53a may notify the information indicating the control mode by voice during the concentration improvement operation. For example, the control unit 53a may notify by a speaker provided in the indoor unit 13.
　以上、集中度向上制御処理において、集中度ＣＲに基づいて、集中度ＣＲを増大させるように空調部を制御することを説明した。なお、本実施の形態において、「集中度ＣＲに基づいて」とは、集中度向上運転を実行するか否か及び集中度向上運転を継続するか否かを、「集中度ＣＲに基づいて」判定しているということを意味している。 As described above, in the concentration improvement control process, the air conditioning unit is controlled to increase the concentration level CR based on the concentration level CR. Note that in this embodiment, "based on the concentration level CR" means that the determination as to whether or not to execute the concentration improvement operation and whether or not to continue the concentration improvement operation is made "based on the concentration level CR."
　以上説明したように、実施の形態１に係る空気調和システム１において、制御部５３ａは、ユーザＨＭの脈波に基づいて集中度ＣＲを判別している。脈波に基づいた集中度ＣＲの推定は、体温に基づく集中度ＣＲの推定よりも信頼度を高くすることが可能である。このため、ユーザＨＭの集中度ＣＲの低下をより高精度で判定し、集中モードを設定し、集中しやすい環境を提供することが可能となる。
　また、集中度向上運転においては、単純に温冷感を下げるだけでなく、ユーザＨＭ自身に室内機１３からの調和空気を直接当てる風あて制御を行うこと、調湿制御を行うことにより、より集中しやすい環境を提供することが可能となる。 As described above, in the air conditioning system 1 according to the first embodiment, the control unit 53a determines the concentration level CR based on the pulse wave of the user HM. Estimation of the concentration level CR based on the pulse wave can be more reliable than estimation of the concentration level CR based on body temperature. This makes it possible to determine a decrease in the concentration level CR of the user HM with higher accuracy, set a concentration mode, and provide an environment that is easy to concentrate.
In addition, in the concentration improvement operation, it is possible to provide an environment that is easier to concentrate in by not simply reducing the sense of warmth or cold, but by performing airflow control to directly blow conditioned air from the indoor unit 13 onto the user HM himself/herself, and by performing humidity control.
（実施の形態１の変形例）
　上記実施の形態１は、種々の変更が可能である。
　例えば、実施形態１では、集中度向上制御処理において、集中度向上運転を行うか否かの判定（ステップＳ１０２）を、集中度ＣＲの差分ＣＢｔ（＝ＣＲt－ＣＲt-1）に基づいて行ったが、これは一例である。任意の集中度ＣＲのサンプルデータ、例えば、サンプルデータＣＲt-mとＣＲt-nを使用してもよい。なお、ｍ、ｎは自然数、ｍ＜ｎである。また、複数の差分の移動平均などを用いてもよい。以下の説明において、異なるタイミングで得られたサンプルデータを使用する場面も同様である。 (Modification of the first embodiment)
The above-mentioned first embodiment can be modified in various ways.
For example, in the first embodiment, in the concentration improvement control process, the determination of whether or not to perform concentration improvement driving (step S102) is made based on the difference CB t (= CR t - CR t-1 ) in the concentration level CR, but this is just one example. Any sample data of the concentration level CR, for example, sample data CR tm and CR tn , may be used. Note that m and n are natural numbers, m < n. Also, a moving average of multiple differences may be used. In the following description, the same applies to situations in which sample data obtained at different times is used.
　実施の形態１では、集中度向上制御処理において、集中度向上運転を行うか否かの判定（ステップＳ１０２）を、集中度ＣＲが低下し且つ集中度ＣＲの差分の絶対値が判定閾値Ｔｈａ以上であるか否かにより行ったが、本開示はこれに限られない。制御部５３ａは、集中度向上運転を行うか否かの判定（ステップＳ１０２）を、集中度ＣＲが低下し且つ集中度ＣＲの比率ＲＣｔ（＝ＣＲt／ＣＲt-1）が、予め定められた判定閾値Ｔｈｃ以上であるか否かで行ってもよい。
　また、集中度向上運転を行うか否かの判定（ステップＳ１０２）を、集中度ＣＲと、予め定められた判定閾値Ｔｈｂとの比較によって行ってもよい。例えば、制御部５３ａは、集中度向上運転を行うか否かの判定（ステップＳ１０２）を、集中度ＣＲが判定閾値Ｔｈｂより小さいか否かで行ってもよい。制御部５３ａは、集中度ＣＲが判定閾値Ｔｈｂより小さい場合、集中度向上運転を実行してもよい。 In the first embodiment, in the concentration improvement control process, the determination of whether or not to perform the concentration improvement operation (step S102) is performed based on whether or not the concentration level CR has decreased and the absolute value of the difference in the concentration levels CR is equal to or greater than the determination threshold value Tha, but the present disclosure is not limited to this. The control unit 53a may determine whether or not to perform the concentration improvement operation (step S102) based on whether or not the concentration level CR has decreased and the ratio RCt (= CRt /CRt -1 ) of the concentration levels CR is equal to or greater than a predetermined determination threshold value Thc.
Furthermore, the determination of whether or not to perform the concentration-improving operation (step S102) may be performed by comparing the concentration level CR with a predetermined determination threshold value Thb. For example, the control unit 53a may determine whether or not to perform the concentration-improving operation (step S102) based on whether or not the concentration level CR is smaller than the determination threshold value Thb. When the concentration level CR is smaller than the determination threshold value Thb, the control unit 53a may execute the concentration-improving operation.
　実施の形態１では、集中度向上制御処理において、集中度向上運転を継続するか否かの判定（ステップＳ１０６）を、集中度ＣＲが判定閾値Ｔｈｂ以上であるか否かにより判定したが、本開示はこれに限られない。制御部５３ａは、集中度向上運転を継続するか否かの判定（ステップＳ１０６）を、前回取得した集中度ＣＲt-1と、今回取得した集中度ＣＲtとの差分ＲＢｔ（＝ＣＲt－ＣＲt-1）が、予め定められた判定閾値Ｔｈｖ以上であるか否かで行ってもよい。また、両者の比率ＲＣｔ（＝ＣＲt／ＣＲt-1）が、予め定められた判定閾値Ｔｈｒ以上であるか否かで判定してもよい。 In the first embodiment, in the concentration improvement control process, the determination of whether or not to continue the concentration improvement operation (step S106) is made based on whether or not the concentration level CR is equal to or greater than the determination threshold Thb, but the present disclosure is not limited to this. The control unit 53a may determine whether or not to continue the concentration improvement operation (step S106) based on whether or not the difference RB t (= CR t - CR t-1 ) between the previously acquired concentration level CR t-1 and the currently acquired concentration level CR t is equal to or greater than a predetermined determination threshold Thv. Alternatively, the control unit 53a may determine whether or not to continue the concentration improvement operation (step S106) based on whether or not the ratio RC t (= CR t /CR t-1 ) between the two is equal to or greater than a predetermined determination threshold Thr.
　また、集中度向上運転において、集中度ＣＲを監視し、集中度ＣＲが上昇するように、制御対象を制御してもよい。
　例えば、集中度向上運転中のあるタイミングｔで、前回の集中度ＣＲt-1と今回の集中度ＣＲtとの差分ＣＢｔ（＝ＣＲt－ＣＲt-1）が正の値であれば、予定されている制御内容をそのまま継続し、差分ＣＢｔが負の値であれば、集中度ＣＲが確実に上昇するように、集中度ＣＲと正の相関を有する制御対象の制御量を予定量よりも大きくしてもよい。例えば、タイミングｔにおいて、湿度をΔＨｔだけ上昇させる制御態様が予定されている場合に、湿度をΔＨｔ＋αだけ上昇させる。ここで、αは正の値で、α＝ｆ（ＣＢｔ）で表される。関数ｆは差分ＣＢｔが小さい（絶対値が大きい）程大きくなる関数である。他の制御対象の制御についても同様である。また、前回の集中度ＣＲt-1と今回の集中度ＣＲtとの比率ＲＣｔ（＝ＣＲt／ＣＲt-1）が「１」未満のときにも、同様の処理が可能である。 In addition, in the driving to improve concentration, the concentration level CR may be monitored, and the controlled object may be controlled so that the concentration level CR increases.
For example, at a certain timing t during the concentration improvement operation, if the difference CB t (= CR t - CR t-1 ) between the previous concentration CR t-1 and the current concentration CR t is a positive value, the scheduled control content is continued as is, and if the difference CB t is a negative value, the control amount of the control object having a positive correlation with the concentration CR may be made larger than the scheduled amount so that the concentration CR is surely increased. For example, if a control mode for increasing the humidity by ΔH t is scheduled at the timing t, the humidity is increased by ΔH t + α. Here, α is a positive value and is expressed as α = f (CB t ). The function f is a function that increases as the difference CB t is smaller (the absolute value is larger). The same applies to the control of other control objects. Also, the same processing is possible when the ratio RC t (= CR t / CR t -1 ) between the previous concentration CR t-1 and the current concentration CR t is less than "1".
　また、集中度ＣＲの目標値ＣＲｏを設定し、生体情報検出装置４３により周期的に集中度ＣＲを取得し、偏差ｅＣＲ（＝ＣＲｏ－ＣＲ）を求め、偏差ｅＣＲに基づいて、ＰＩＤ制御（比例積分微分制御）を用いて、温度、湿度、風量、風向の変更量ΔＴ、ΔＨ、ΔＦ、ΔＬ、を次式で示すように制御してもよい。
ΔＴ＝ａ1・ｅＣＲ＋ｂ1・∫ｅＣＲｄｔ＋ｃ1・ｅＣＲ／ｄｔ
ΔＨ＝ａ2・ｅＣＲ＋ｂ2・∫ｅＣＲｄｔ＋ｃ2・ｅＣＲ／ｄｔ
ΔＦ＝ａ3・ｅＣＲ＋ｂ3・∫ｅＣＲｄｔ＋ｃ3・ｅＣＲ／ｄｔ
ΔＬ＝ａ4・ｅＣＲ＋ｂ4・∫ｅＣＲｄｔ＋ｃ4・ｅＣＲ／ｄｔ
　なお、ａ1，...ａ４，ｂ1，...ｂ４，ｃ1，...ｃ４，は係数である。 In addition, a target value CR o for the concentration level CR may be set, the concentration level CR may be periodically acquired using the bio-information detection device 43, and the deviation eCR (= CR o - CR) may be calculated. Based on the deviation eCR, PID control (proportional integral differential control) may be used to control the change amounts ΔT, ΔH, ΔF, and ΔL of the temperature, humidity, air volume, and air direction as shown in the following equation.
ΔT＝ a1・eCR+ b1・∫eCRdt+ c1・eCR/dt
ΔH＝ a2 ·eCR+ b2 ·∫eCRdt+ c2 ·eCR/dt
ΔF＝ a3 ·eCR+ b3 ·∫eCRdt+ c3 ·eCR/dt
ΔL＝ a4 ·eCR+ b4 ·∫eCRdt+ c4 ·eCR/dt
Note that a 1 , ...a 4 , b 1 , ...b 4 , c 1 , ...c 4 are coefficients.
　また、機械学習技術を用いてもよい。この場合、制御部５３ａは、機械学習装置を備える。機械学習装置は、例えば、集中度ＣＲの目標値ＣＲｏ及び偏差ｅＣＲと、温度と湿度と風量と風向の目標値Ｔｏ、Ｈｏ、Ｆｏ、Ｌｏとの関係を学習データとして学習する。機械学習装置は、実際の制御の場面では、目標値ＣＲｏと偏差ｅＣＲとを入力し、温度の目標値Ｔｏと湿度の目標値Ｈｏと風量の目標値Ｆｏと風向の目標値Ｌｏを出力する。制御部５３ａは、各目標値が得られるように、室内機空調部８２を制御し、さらに、制御部５１ａを介して室外機空調部８１を制御する。
　なお、機械学習装置の入力を、例えば、集中度ＣＲの目標値ＣＲｏとその時点の温度Ｔと湿度Ｈと風量ＤＦと風向Ｌとし、出力を制御対象別の目標値としてもよい。 Machine learning technology may also be used. In this case, the control unit 53a includes a machine learning device. The machine learning device learns, for example, the relationship between the target value CR o and deviation eCR of the concentration level CR and the target values To, Ho, Fo, and Lo of the temperature, humidity, air volume, and wind direction as learning data. In an actual control situation, the machine learning device inputs the target value CR o and deviation eCR, and outputs the target value To of the temperature, the target value Ho of the humidity, the target value Fo of the air volume, and the target value Lo of the wind direction. The control unit 53a controls the indoor unit air conditioning unit 82 so that each target value is obtained, and further controls the outdoor unit air conditioning unit 81 via the control unit 51a.
The input to the machine learning device may be, for example, the target value CR o of the concentration level CR, the temperature T, humidity H, air volume DF, and wind direction L at that time, and the output may be a target value for each control object.
　実施の形態１では、集中度向上運転をステップＳ１０３で実行した後に、制御部５３ａは、集中度向上運転の実行時間の判定処理（ステップＳ１０４）を行っているが、本開示はこれに限られない。制御部５３ａは、ステップＳ１０４の判定処理を行うことなく、集中モード終了の指示あるいは空調終了の指示があるまで、継続して集中度向上運転を継続してもよい。 In the first embodiment, after the concentration improvement operation is executed in step S103, the control unit 53a performs a process of determining the execution time of the concentration improvement operation (step S104), but the present disclosure is not limited to this. The control unit 53a may continue the concentration improvement operation until an instruction to end the concentration mode or an instruction to end the air conditioning is received, without performing the determination process of step S104.
　また、制御部５３ａは、集中度ＣＲが低下且つ差分の絶対値は判定閾値Ｔｈａ以上、ではない、と判定した場合（ステップＳ１０２：Ｎｏ）、集中度向上制御処理を終了してもよい。 In addition, if the control unit 53a determines that the concentration level CR has decreased and the absolute value of the difference is not equal to or greater than the determination threshold value Tha (step S102: No), the control unit 53a may terminate the concentration level improvement control process.
　実施の形態１では、制御部５３ａは、集中度向上運転を予め定められた時間以上実施したら（ステップＳ１０４：Ｙｅｓ）、集中度向上運転を停止し（ステップＳ１０７）、集中モードを停止するか否かの判定を行っていた（ステップＳ１０８）が、集中度向上運転を停止（ステップＳ１０７）したら、集中モードを停止させてもよい。 In the first embodiment, when the concentration improvement operation is performed for a predetermined time or longer (step S104: Yes), the control unit 53a stops the concentration improvement operation (step S107) and determines whether to stop the concentration mode (step S108). However, when the concentration improvement operation is stopped (step S107), the concentration mode may be stopped.
　上記実施の形態１では、集中度向上運転として、温度、湿度、風量、風向等の制御対象を目標値まで一定の変化率で変化させる例を示したが、どの可変量を制御対象にするか、どのような変化態様にするか等については、ユーザＨＭの集中度ＣＲを増大させる限りにおいて、任意である。 In the above embodiment 1, an example was given of the concentration improvement operation in which the controlled objects such as temperature, humidity, air volume, and wind direction are changed at a constant rate of change to the target value, but the variable quantity to be controlled and the manner of change are arbitrary as long as they increase the concentration level CR of the user HM.
　例えば、温度、湿度、風量、風向等の制御対象を目標値まで徐々に変化させるのではなく、移行期間Ｐｓをほぼ０（ゼロ）として、短い時間である瞬時に変化させて、以後は、目標値を維持するようにしてもよい。なお、風向だけを一気に目標値まで変化させて、温度、湿度、風量については、目標値まで徐々に変化させてもよい。例えば、制御部５３ａは、集中度向上運転を開始すると、ベーン３４を調整して風向を一気に制御して、生体情報検出装置４３と赤外線センサ４４とで検出されるユーザＨＭの足下、腰、胸、顔等の予め設定された位置に当たるように風向を制御してもよい。 For example, rather than gradually changing the controlled objects such as temperature, humidity, air volume, and wind direction to the target values, the transition period Ps may be set to approximately 0 (zero), and the changes may be made instantaneously for a short period of time, after which the target values may be maintained. Alternatively, only the wind direction may be changed to the target value in one go, while the temperature, humidity, and air volume may be changed gradually to their target values. For example, when the control unit 53a starts the concentration improvement operation, it may adjust the vanes 34 to control the wind direction in one go, and control the wind direction so that the wind hits preset positions such as the feet, waist, chest, and face of the user HM detected by the bioinformation detection device 43 and infrared sensor 44.
　また、図８（Ａ）、（Ｂ）、（Ｃ）に示すように、各制御量を、時間に対して線形に、曲線的に、あるいは、段階的に変化させてもよい。図８（Ａ）、（Ｂ）に示すように、時間の経過に伴って変化量を小さくすることにより、集中モード開始時の変化量を大きくして、眠気を抑制して覚醒を促すことができる。また、図８（Ｃ）に示すように、時間の経過に伴って変化量を大きくすることにより、覚醒を持続させることができる。
　なお、集中モード開始直後は、予め定められた制御態様或いは制御履歴に基づいて集中度向上運転を実施し、その後は、ユーザＨＭの集中度ＣＲの変化に応じて運転態様を変更するようにしてもよい。 Also, as shown in Figures 8(A), (B), and (C), each control amount may be changed linearly, curvilinearly, or stepwise with respect to time. As shown in Figures 8(A) and (B), by decreasing the amount of change over time, the amount of change at the start of the concentration mode can be increased, suppressing drowsiness and promoting wakefulness. Also, as shown in Figure 8(C), by increasing the amount of change over time, wakefulness can be maintained.
Incidentally, immediately after the concentration mode starts, a concentration improving operation may be performed based on a predetermined control mode or control history, and thereafter the operation mode may be changed in response to a change in the concentration level CR of the user HM.
　また、例えば、集中モードにおいて、温度、風向については調整するが、湿度と風量については、調整しないというように、一部の制御対象のみを選択的に調整するようにしてもよい。 Also, for example, in the concentrated mode, the temperature and wind direction may be adjusted, but the humidity and air volume may not be adjusted, so that only some of the control targets are selectively adjusted.
　また、制御の対象とする制御対象を経過時間と共に変化させてもよい。例えば、図９に例示するように、集中モードの開始直後には、４つの各制御対象の全てを集中用に制御し、時刻Ｔ１以後、風向を集中用の制御の対象から除外し、時刻Ｔ２以後、風量を集中用の制御の対象から外し、時刻Ｔ３以降、湿度を集中用の制御の対象から外し．．．というように、集中モード用の制御の対象を時間の経過に伴って変化させてもよい。 The control objects to be controlled may also be changed over time. For example, as shown in FIG. 9, immediately after the start of the concentration mode, all four control objects are controlled for concentration, and after time T1, the air direction is excluded from the objects of the concentration mode control, after time T2, the air volume is excluded from the objects of the concentration mode control, and after time T3, the humidity is excluded from the objects of the concentration mode control, etc. In this way, the control objects for the concentration mode may be changed over time.
　実施の形態１では、制御部５３ａは、集中度向上運転の際、風あて制御を行っていたが、上下の風向き、または、左右の風向きをスイング動作させて、気流によるユーザＨＭへの刺激を実現してもよい。 In the first embodiment, the control unit 53a controls the wind direction during the concentration improvement operation, but the wind direction may be swung up and down or left and right to stimulate the user HM with the airflow.
　上記実施の形態１では、集中度向上運転の際、暖房または冷房の運転モードにおいて、制御を行っていたが、冷房も暖房も不要な環境においては、送風の運転モードにおいて制御を行ってもよい。この場合、制御部５３ａは、風量と風向きを制御対象とし、温度と湿度は制御対象としなくてもよい。 In the above embodiment 1, control is performed in the heating or cooling operation mode during the concentration improvement operation, but in an environment where neither cooling nor heating is required, control may be performed in the air blowing operation mode. In this case, the control unit 53a may control the air volume and air direction, but not the temperature and humidity.
　また、制御部５３ａは、集中度向上運転の実行時間を、予め定められた時間ではなく、集中度ＣＲの変化に応じて、変更してもよい。例えば、集中度向上運転の実行開始直後から、集中度ＣＲの上昇率が小さい状態が続いていたが、集中度向上運転の実行時間が予め定められた時間の直前になった時、集中度ＣＲの上昇率が大きくなった場合、集中度向上運転の実行時間を長くしてもよい。 The control unit 53a may also change the execution time of the concentration improvement operation in response to changes in the concentration level CR, rather than to a predetermined time. For example, if the rate of increase in the concentration level CR has remained small since immediately after the start of the execution of the concentration improvement operation, but the rate of increase in the concentration level CR becomes large just before the execution time of the concentration improvement operation reaches the predetermined time, the execution time of the concentration improvement operation may be lengthened.
　実施の形態１では、制御部５３ａは、集中度向上運転を予め定められた時間以上実施した場合（ステップＳ１０４：Ｙｅｓ）、集中度向上運転を停止（ステップＳ１０７）していたが、集中度ＣＲが判定閾値Ｔｈｂ以上になるまで、集中度向上運転を実行してもよい。 In the first embodiment, if the concentration improvement operation has been performed for a predetermined time or longer (step S104: Yes), the control unit 53a stops the concentration improvement operation (step S107), but the concentration improvement operation may be performed until the concentration CR becomes equal to or greater than the judgment threshold value Thb.
　実施の形態１では、制御部５３ａは、集中度向上運転を停止（ステップＳ１０７）した後、集中モードが停止していないと判定した場合（ステップＳ１０８：Ｎｏ）、ステップＳ１０１へ処理を戻していたが、本開示はこれに限られない。集中度ＣＲの向上は、運転状態の変化によって効果が生じる傾向にある。このため、制御部５３ａは、集中度向上運転を停止（ステップＳ１０７）した後、集中モードが停止していないと判定した場合（ステップＳ１０８：Ｎｏ）、すぐにステップＳ１０１へ処理を戻すのではなく、予め定められた時間が経過してから、ステップＳ１０１へ処理を戻してもよい。 In the first embodiment, if the control unit 53a determines that the concentration mode has not stopped (step S108: No) after stopping the concentration improvement operation (step S107), the control unit 53a returns the process to step S101, but the present disclosure is not limited to this. The improvement of the concentration level CR tends to be caused by a change in the driving state. For this reason, if the control unit 53a determines that the concentration mode has not stopped (step S108: No) after stopping the concentration improvement operation (step S107), the control unit 53a may return the process to step S101 after a predetermined time has elapsed, rather than immediately returning the process to step S101.
　上記実施の形態１では、集中度向上運転を行うか否かの判定を、集中度ＣＲが低下し且つ差分の絶対値が判定閾値Ｔｈａ以上であるか否かの判定処理（ステップＳ１０２）において、差分の絶対値と１つの判定閾値Ｔｈａとの比較で行ったが、複数の判定閾値を設定してもよい。例えば、図１０は、２つの判定閾値Ｔｈａ１とＴｈａ２を使用する例を示す。なお、Ｔｈａ１＞Ｔｈａ２である。この例では、集中度ＣＲの低下時の差分の絶対値が、第1の判定閾値Ｔｈａ１以上の時は、４つの制御対象の全てを集中モード用に制御し、集中度ＣＲの低下時の差分の絶対値が、第２の判定閾値Ｔｈａ２以上、かつ、第１の判定閾値Ｔｈａ１より小さいときには、温度と風向を集中モード用の制御の対象とし、集中度ＣＲの低下時の差分の絶対値が、第２の判定閾値Ｔｈａ２より小さいときには、温度のみを集中モード用に制御する。 In the above-mentioned embodiment 1, the determination of whether or not to perform the concentration improvement operation was made by comparing the absolute value of the difference with one judgment threshold Tha in the determination process (step S102) of whether or not the concentration level CR has decreased and the absolute value of the difference is equal to or greater than the judgment threshold Tha. However, multiple judgment thresholds may be set. For example, FIG. 10 shows an example in which two judgment thresholds Tha1 and Tha2 are used. Note that Tha1>Tha2. In this example, when the absolute value of the difference when the concentration level CR has decreased is equal to or greater than the first judgment threshold Tha1, all four control objects are controlled for the concentration mode, when the absolute value of the difference when the concentration level CR has decreased is equal to or greater than the second judgment threshold Tha2 and smaller than the first judgment threshold Tha1, the temperature and wind direction are controlled for the concentration mode, and when the absolute value of the difference when the concentration level CR has decreased is smaller than the second judgment threshold Tha2, only the temperature is controlled for the concentration mode.
　また、図１１（Ａ）に示すように、集中度向上運転の実施日時、運転態様、集中度ＣＲの変化、集中度ＣＲの上昇率等を、記憶部５３ｂ又は外部記憶装置に記録して、履歴情報を形成し、次回以降の集中度向上運転にフィードバックしてもよい。例えば、運転態様の異なる集中度向上運転を複数回実行し、その後、記録されている運転態様のうちで、集中度ＣＲの上昇率が最も高い制御運転態様を特定し、その運転態様と同一又は類似の制御を行うようにしてもよい。なお、集中度ＣＲの上昇率は、例えば、集中モード開始時点の集中度ＣＲt=0と一定時間ＴＥ経過時点での集中度ＣＲt=TEの比の値ＣＲt=TE／ＣＲt=0として求めればよい。 Also, as shown in Fig. 11 (A), the date and time of the concentration improvement operation, the driving mode, the change in the concentration level CR, the increase rate of the concentration level CR, etc. may be recorded in the memory unit 53b or an external storage device to form history information and fed back to the next and subsequent concentration improvement operations. For example, the concentration improvement operation with different driving modes may be performed multiple times, and then, among the recorded driving modes, the controlled driving mode with the highest increase rate of the concentration level CR may be identified, and control may be performed that is the same as or similar to that driving mode. The increase rate of the concentration level CR may be calculated, for example, as the ratio CR t=TE /CR t=0 between the concentration level CR t= 0 at the start of the concentration mode and the concentration level CR t=TE after a certain time TE has elapsed.
　また、ユーザＨＭを識別し、図１１（Ｂ）に例示するように、集中度向上運転の履歴をユーザＨＭ毎に記録してもよい。この場合、集中モード起動時に、室内空間７１にいるユーザＨＭを特定して、そのユーザＨＭの履歴情報に基づいて、例えば、集中度ＣＲが最も向上したときの集中度向上運転の運転態様を再現することで、集中度ＣＲの向上を期待できる。
　なお、集中モード開始直後は、履歴に基づいて集中度向上運転を実施し、その後は、ユーザＨＭの集中度ＣＲの変化（＝ＣＲt－ＣＲt-1）あるいは変化率（＝（ＣＲt－ＣＲt-1）／ＣＲt）に応じて運転態様を調整するようにしてもよい。例えば、それまでの集中度向上運転で、集中度ＣＲがほとんど変化しない場合に、各制御対象の変更量を従前の変化量あるいは予定量よりも大きくする、集中度ＣＲが急激に上昇した場合に、各制御対象の変更量を従前の変化量あるいは予定量よりも小さくする、等の調整を行ってもよい。 In addition, the user HM may be identified, and the history of the concentration-improving driving may be recorded for each user HM, as shown in Fig. 11(B) . In this case, when the concentration mode is started, the user HM in the indoor space 71 may be identified, and based on the history information of the user HM, for example, the driving mode of the concentration-improving driving when the concentration level CR was most improved may be reproduced, which is expected to improve the concentration level CR.
It should be noted that immediately after the concentration mode starts, a concentration-improving operation may be performed based on the history, and thereafter the operating mode may be adjusted according to the change in the concentration level CR of the user HM (=CR t - CR t-1 ) or the rate of change (=(CR t - CR t-1 )/CR t ). For example, if the concentration level CR has hardly changed during the previous concentration-improving operation, the amount of change in each control object may be made larger than the previous amount of change or the planned amount; if the concentration level CR has risen sharply, the amount of change in each control object may be made smaller than the previous amount of change or the planned amount.
　また、好適な運転態様を選択する際に、曜日、時間帯、季節等の時間的要因を参照してもよい。
　例えば、休日の午後は、平日よりも風量を小さくした方が、集中度ＣＲが向上できている傾向が、履歴から判別できる場合、集中モードの起動時点が休日の午後に該当すれば、風量を小さくした態様で集中度向上運転を開始するようにしてもよい。 Furthermore, time factors such as the day of the week, the time period, and the season may be taken into consideration when selecting a suitable driving mode.
For example, if it can be determined from the history that there is a tendency for the concentration level CR to be improved by reducing the airflow on holiday afternoons compared to weekdays, then if the concentration mode is activated on a holiday afternoon, the concentration level improving operation may be started with the airflow reduced.
　ドップラーセンサは、指向性を有し、ジンバル機構等により指向方向を制御可能であったが、本開示はこれに限られない。ドップラーセンサは、指向方向を制御できない固定した形態であってもよい。室内空間７１に存在するユーザＨＭの脈波を検出すべく、単数に限らず、複数のドップラーセンサが備えられていてもよい。また、室内機１３がドップラーセンサを備えるのみならず、壁、天井等にドップラーセンサが設置されてもよいし、例えば、マイクロ波の照射方向が部屋の中央を向くように、部屋の四隅にドップラーセンサが三脚で固定されてもよい。 Although the Doppler sensor has directionality and the directional direction can be controlled by a gimbal mechanism or the like, the present disclosure is not limited to this. The Doppler sensor may be in a fixed form in which the directional direction cannot be controlled. In order to detect the pulse waves of the user HM present in the indoor space 71, multiple Doppler sensors may be provided, not limited to a single one. Furthermore, not only may the indoor unit 13 be provided with a Doppler sensor, but the Doppler sensor may be installed on a wall, ceiling, etc., and, for example, the Doppler sensor may be fixed on a tripod to the four corners of the room so that the direction of microwave irradiation faces the center of the room.
　実施の形態１では、赤外線センサ４４とドップラーセンサを備えていた。赤外線センサ４４が人の位置を特定し、ドップラーセンサが人体の脈波を検出して、両者が協働してセンサの役割を果たしていたが、本開示はこれに限られない。空気調和装置２は、ドップラーセンサのみを備え、ドップラーセンサが人体の脈波の検出のみならず、人の位置を特定してもよい。また、赤外線センサ４４の検出とドップラーセンサの検出とを組み合わせて、信頼度を高めてもよい。 In the first embodiment, an infrared sensor 44 and a Doppler sensor were provided. The infrared sensor 44 identified the position of a person, and the Doppler sensor detected the pulse waves of the human body, and the two worked together to fulfill the role of sensors, but the present disclosure is not limited to this. The air conditioning device 2 may be provided with only a Doppler sensor, and the Doppler sensor may not only detect the pulse waves of the human body but also identify the position of the person. Furthermore, the detection by the infrared sensor 44 and the detection by the Doppler sensor may be combined to increase reliability.
　実施の形態１では、ドップラーセンサによって人体の脈波を検出したが、任意の種類のセンサによって脈波を検出してもよい。例えば、２４ＧＨｚ～７９ＧＨｚのＦＭＣＷ（Frequency Modulated Continuous Wave radar）方式センサによって人体の脈波を検出してもよい。また、赤外線、赤色光、緑色波長等の光を生体に向けて照射し、生体内で反射した光、又は、生体を透過した光を受光素子で計測することにより脈波を計測してもよい。また、非接触型のセンサに限らず、人体に接触して検出を行う接触型センサでもよい。例えば、心電図計を人体で計測し、心電図から脈波を抽出してもよい。 In the first embodiment, the human pulse wave is detected by a Doppler sensor, but the pulse wave may be detected by any type of sensor. For example, the human pulse wave may be detected by a 24 GHz to 79 GHz FMCW (Frequency Modulated Continuous Wave radar) sensor. The pulse wave may also be measured by irradiating a living body with infrared light, red light, green light, or other light and measuring the light reflected within the living body or the light that has passed through the living body with a light receiving element. The sensor is not limited to a non-contact type, and may be a contact type sensor that detects by contacting the human body. For example, an electrocardiogram may be used to measure the human body and the pulse wave may be extracted from the electrocardiogram.
　実施の形態１において、空気調和装置２は制御装置５０を内部に備えていたが、制御装置５０は空気調和装置２の外部に配置されてもよい。この場合、制御装置５０は、例えば、図１２に示すように、空気調和装置２にネットワークＮＷを介して接続される。この場合、空気調和装置２は、例えば、外部と通信を行う通信装置５６を備える。通信装置５６は、外部に配置された制御装置５０の室外機制御部５１と、空気調和装置２の室外機空調部８１との間の通信を可能とし、外部に配置された制御装置５０の室内機制御部５３とセンサ群４０，リモコン５５、室内機空調部８２との間の通信を可能とする。 In the first embodiment, the air conditioning apparatus 2 has the control device 50 inside, but the control device 50 may be placed outside the air conditioning apparatus 2. In this case, the control device 50 is connected to the air conditioning apparatus 2 via a network NW, for example, as shown in FIG. 12. In this case, the air conditioning apparatus 2 has, for example, a communication device 56 that communicates with the outside. The communication device 56 enables communication between the outdoor unit control unit 51 of the control device 50 placed outside and the outdoor unit air conditioning unit 81 of the air conditioning apparatus 2, and enables communication between the indoor unit control unit 53 of the control device 50 placed outside and the sensor group 40, the remote control 55, and the indoor unit air conditioning unit 82.
　また、例えば、制御装置５０は、ネットワークＮＷに接続されたサーバ装置５７から構成されてもよい。この場合、例えば、室外機制御部５１及び室内機制御部５３が実行する制御処理を実行する制御プログラムをサーバ装置５７にインストールして、室外機制御機能及び室内機制御機能をサーバ装置５７上に構築すればよい。なお、サーバ装置５７は、パーソナルコンピュータにより実現されてもよい。 Furthermore, for example, the control device 50 may be configured from a server device 57 connected to the network NW. In this case, for example, a control program that executes the control processing executed by the outdoor unit control unit 51 and the indoor unit control unit 53 may be installed in the server device 57, and an outdoor unit control function and an indoor unit control function may be constructed on the server device 57. Note that the server device 57 may be realized by a personal computer.
　上記実施の形態においては、空気調和装置２が生体情報検出装置４３を備えていたが、生体情報検出装置４３は空気調和装置２の外部にあってもよい。例えば、生体情報検出装置４３は、室内空間７１を形成する天井、壁、床等に配置されてもよい。また、ウエアラブルな生体情報検出装置を用いてもよい。この場合、ウエアラブルな生体情報検出装置と室内機制御部５３との間を無線通信又は有線通信により接続することが望ましい。 In the above embodiment, the air conditioning apparatus 2 is equipped with the biological information detection device 43, but the biological information detection device 43 may be located outside the air conditioning apparatus 2. For example, the biological information detection device 43 may be placed on the ceiling, wall, floor, etc. that form the indoor space 71. Also, a wearable biological information detection device may be used. In this case, it is desirable to connect the wearable biological information detection device and the indoor unit control unit 53 via wireless communication or wired communication.
　また、近時の携帯情報端末には、様々な生体情報を測定し、解析する機能を有するものがある。この種の携帯情報端末をセンサとして用いて、例えば、図３の構成で、情報機器９０と室内機制御部５３とを有線又は無線で直接接続し、あるいは、ネットワークＮＷ経由で接続し、情報機器９０が生体情報を取得し、さらにこれを解析して集中度ＣＲを求め、室内機制御部５３に通知してもよい。また、情報機器９０は、生体情報を取得して、室内機制御部５３に送信し、室内機制御部５３が生体情報を解析して、集中度ＣＲを求めてもよい。生体情報検出装置４３は、例えば、ドップラー信号を受信するのみで、室内機制御部５３がドップラー信号を解析して脈波を抽出し、さらに、脈波を解析して集中度ＣＲを求めてもよい。 Moreover, some recent portable information terminals have the function of measuring and analyzing various types of bioinformation. Using this type of portable information terminal as a sensor, for example, in the configuration of FIG. 3, the information device 90 and the indoor unit control unit 53 may be directly connected by wire or wirelessly, or connected via a network NW, and the information device 90 may acquire the bioinformation, analyze it to determine the concentration level CR, and notify the indoor unit control unit 53 of the same. The information device 90 may also acquire the bioinformation and transmit it to the indoor unit control unit 53, which may analyze the bioinformation to determine the concentration level CR. For example, the bioinformation detection device 43 may simply receive a Doppler signal, and the indoor unit control unit 53 may analyze the Doppler signal to extract a pulse wave, and further analyze the pulse wave to determine the concentration level CR.
　実施の形態１において、集中度向上制御処理は、ユーザＨＭがリモコン５５を用いて集中モードを選択することにより開始されていたが、本開示はこれに限られない。任意の態様で開始と終了を設定できる。例えば、赤外線センサ４４のような人感センサによって室内空間７１に人を検知すると、集中度向上制御処理を自動的に開始し、人を検知しなくなったら終了してもよい。 In the first embodiment, the concentration improvement control process is started by the user HM selecting the concentration mode using the remote control 55, but the present disclosure is not limited to this. The start and end can be set in any manner. For example, when a human presence sensor such as the infrared sensor 44 detects a person in the indoor space 71, the concentration improvement control process may be automatically started, and may be ended when the person is no longer detected.
　また、集中度向上制御処理において、集中度ＣＲが、人が不在時に示されるような例外値になった場合に、集中度向上制御処理の終了、または、空気調和装置２の運転を停止してもよい。例えば、取得した集中度ＣＲが「ゼロ」の場合、制御部５３ａは、空気調和装置２の運転を停止してもよい。 In addition, in the concentration improvement control process, if the concentration level CR becomes an exceptional value such as that shown when no one is present, the concentration improvement control process may be terminated or the operation of the air conditioning device 2 may be stopped. For example, if the acquired concentration level CR is "zero," the control unit 53a may stop the operation of the air conditioning device 2.
　上記実施の形態においては、集中モードでは、温度、湿度、風量、風向を制御対象としたが、これらの制御対象の一部に代えて、あるいは、これらの制御対象と共に他のパラメータを制御対象としてもよい。例えば、温調タイミングを通常運転時での温調タイミングから変更する制御を実行してもよい。ここで、温調タイミングとは、温調制御をオン又はオフするタイミングを意味する。ここで、「温調オフ」は、室外機１１の圧縮機２１を止め、「冷やす」又は「暖める」を止めることを意味し、「温調オン」は、室外機１１の圧縮機２１を稼働させ、「冷やす」又は「暖める」を行うことを意味する。「温調オフ」のタイミングは、室温ＴＲとユーザＨＭに設定された設定温度ＴＳの温度差ΔＴＲがΔＴoff℃に到達した時点、「温調オン」のタイミングは、室温ＴＲと設定温度ＴＳの温度差ΔＴＲがΔＴon℃になった時点に設定される。例えば、通常モードの冷房運転で、設定温度が２８℃で、温調オフのタイミングΔＴoff＝－２℃が設定され、温調オンのタイミングが温度差ΔＴon＝０℃に設定されている場合を想定する。この場合、室温ＴＲが設定温度の２６℃まで低下して温度差ΔＴＲが－２℃になると、圧縮機２１を停止して「冷やす」ことを停止する。その後、室温ＴＲが２８℃まで上昇し、温度差ΔＴＲが０℃になると、圧縮機２１を稼働して「冷やす」ことを再開する。 In the above embodiment, the temperature, humidity, air volume, and air direction are the control objects in the concentrated mode, but other parameters may be controlled instead of some of these control objects, or in addition to these control objects. For example, control may be performed to change the temperature control timing from the temperature control timing during normal operation. Here, temperature control timing means the timing to turn temperature control on or off. Here, "temperature control off" means stopping the compressor 21 of the outdoor unit 11 to stop "cooling" or "heating", and "temperature control on" means operating the compressor 21 of the outdoor unit 11 to perform "cooling" or "heating". The timing of "temperature control off" is set at the point when the temperature difference ΔTR between the room temperature TR and the set temperature TS set in the user HM reaches ΔToff°C, and the timing of "temperature control on" is set at the point when the temperature difference ΔTR between the room temperature TR and the set temperature TS becomes ΔTon°C. For example, assume that in normal cooling mode operation, the set temperature is 28°C, the temperature control off timing ΔToff = -2°C, and the temperature control on timing is set to a temperature difference ΔTon = 0°C. In this case, when the room temperature TR drops to the set temperature of 26°C and the temperature difference ΔTR becomes -2°C, the compressor 21 is stopped and "cooling" is stopped. After that, when the room temperature TR rises to 28°C and the temperature difference ΔTR becomes 0°C, the compressor 21 is operated and "cooling" is resumed.
　例えば、集中度向上制御処理において、集中度向上運転実行時（ステップＳ１０３）に、通常モード用に設定されている温調オンオフタイミングを変更する制御を行ってもよい。例えば、図６のステップＳ１０３で、温調オンのタイミングを規定する温度差ΔＴon℃を通常モードよりも小さく－１℃とし、温調オフのタイミングを規定する温度差ΔＴoff℃を通常モードより大きい－１．５℃とする。この場合、上記の例で、室温ＴＲが設定温度ＴＳよりも１℃低い２７℃に達すると、室温ＴＲと設定温度ＴＳの差がΔＴon℃に達するため、圧縮機２１を稼働して「冷やす」ことを再開する。また、室温ＴＲが、設定温度ＴＳのマイナス１．５℃の２６．５℃に達したら、「冷やす」ことを止める制御を実行する。 For example, in the concentration improvement control process, when the concentration improvement operation is being performed (step S103), control may be performed to change the temperature control on/off timing set for the normal mode. For example, in step S103 of FIG. 6, the temperature difference ΔT on ° C. that specifies the temperature control on timing is set to -1 ° C., smaller than in the normal mode, and the temperature difference ΔT off ° C. that specifies the temperature control off timing is set to -1.5 ° C., larger than in the normal mode. In this case, in the above example, when the room temperature TR reaches 27 ° C., which is 1 ° C. lower than the set temperature TS, the difference between the room temperature TR and the set temperature TS reaches ΔT on ° C., so the compressor 21 is operated to resume "cooling". Also, when the room temperature TR reaches 26.5 ° C., which is 1.5 ° C. lower than the set temperature TS, control is performed to stop "cooling".
　実施の形態１では、集中度ＣＲに基づいて、空気調和装置２のみを空調制御したが、これに加えて、ユーザＨＭが使用する機器を制御してもよい。ユーザＨＭが使用する機器は、ユーザＨＭの集中度ＣＲに影響を与えるような環境を調整する。空気調和装置２に加えて、図１３（Ａ）に例示するように、室外機１１又は室内機１３に直接、あるいはネットワークＮＷを介して接続された外部機器、例えば、照明機器９１ａ,９１ｂ、扇風機９２、給湯器、空気清浄機、換気扇などの外部機器を制御してもよい。これらの外部機器は、空気調和装置２からの有線信号又は赤外線信号等の無線信号、又は、クラウドサーバ経由で操作されうる。これらの外部機器は、家屋３に配置され、室内空間７１に所在するユーザＨＭの集中度ＣＲに影響を与えうる態様で設置及び利用されている。 In the first embodiment, only the air conditioning device 2 is controlled based on the concentration level CR, but in addition to this, devices used by the user HM may also be controlled. The devices used by the user HM adjust the environment so as to affect the concentration level CR of the user HM. In addition to the air conditioning device 2, as illustrated in FIG. 13(A), external devices connected directly to the outdoor unit 11 or the indoor unit 13 or via the network NW, such as lighting devices 91a, 91b, an electric fan 92, a water heater, an air purifier, and a ventilation fan, may also be controlled. These external devices can be operated by wired signals or wireless signals such as infrared signals from the air conditioning device 2, or via a cloud server. These external devices are arranged in the house 3, and are installed and used in a manner that can affect the concentration level CR of the user HM located in the indoor space 71.
　この場合、室内機制御部５３の記憶部５３ｂには、図１３（Ｂ）に例示するような集中モード用制御態様テーブルが格納される。このテーブルには、集中度向上運転を実行する際に、制御する外部機器の識別情報と制御態様とが登録されている。 In this case, a control mode table for the concentration mode, as shown in FIG. 13(B), is stored in the memory unit 53b of the indoor unit control unit 53. In this table, identification information and control modes of the external devices to be controlled when performing the concentration improvement operation are registered.
　例えば、図６のステップＳ１０３で、室内機制御部５３は、集中モード用制御態様テーブルの設定内容に従い、照明機器９１ａ,９１ｂにコマンドを送り、照明１の調光度を６０％まで降下させることを指示し、照明２の調光度を１００％レベルに設定する。照明機器９１ａ,９１ｂに対する制御内容は、例えば、照明１は室内空間７１の全体を明るくする電灯で、照明２はデスクライトの場合、室内全体は少し暗くして、デスクの手元を明るくすると、集中力を高められる傾向に基づいている。ネットワークＮＷを介してサーバ装置５７にコマンドを送り、サーバ装置５７に接続されている扇風機９２の風力を「２」レベルに設定する。また、例えば、扇風機９２が、自然な風を送るリズム風モード機能を有する場合、室内機制御部５３は動作モードをリズム風モードに切り替える。さらに、外部機器が給湯器の場合、室内機制御部５３は、設定温度を高めに設定する。外部機器が空気清浄機の場合、室内機制御部５３は、運転中の音が気にならないような、静かな設定に切り替える。また、外部機器が換気扇の場合、室内機制御部５３は、換気扇を稼働させ、室内の二酸化炭素濃度を下げ、集中度ＣＲを向上させる。室内機制御部５３は、これらの外部機器の制御を、ステップＳ１０３の集中度向上運転時に行う。空気調和装置２に加えて外部機器が制御されることによって、集中度ＣＲの更なる向上が実現され得る。 For example, in step S103 of FIG. 6, the indoor unit control unit 53 sends a command to the lighting devices 91a and 91b according to the settings in the control mode table for the concentration mode, instructing them to lower the dimming level of the light 1 to 60% and to set the dimming level of the light 2 to 100%. The control contents for the lighting devices 91a and 91b are based on the tendency that, for example, if the light 1 is an electric light that brightens the entire indoor space 71 and the light 2 is a desk light, concentration can be improved by making the entire room a little darker and brightening the area around the desk. A command is sent to the server device 57 via the network NW, and the wind power of the electric fan 92 connected to the server device 57 is set to level "2". Also, for example, if the electric fan 92 has a rhythm wind mode function that blows natural wind, the indoor unit control unit 53 switches the operation mode to the rhythm wind mode. Furthermore, if the external device is a water heater, the indoor unit control unit 53 sets the set temperature to a higher level. If the external device is an air purifier, the indoor unit control unit 53 switches to a quiet setting so that the noise during operation is not distracting. If the external device is a ventilation fan, the indoor unit control unit 53 operates the ventilation fan to reduce the carbon dioxide concentration in the room and improve the concentration rate CR. The indoor unit control unit 53 controls these external devices during the concentration rate improvement operation in step S103. By controlling the external device in addition to the air conditioning device 2, a further improvement in the concentration rate CR can be achieved.
　また、室内機制御部５３は、通常運転時は、室内熱交換器２５の吸い込み口近傍の空気温度が設定温度に達するように空調運転を行うが、集中モードでは、人が実際に感じる体感温度を、目標温度である設定温度に近づけるように空調運転を行ってもよい。この場合、図１の構成において、例えば、赤外線センサ４４に隣接して、ユーザＨＭの体感温度を検出する体感温度センサを配置し、図６のステップＳ１０３で、温度センサ４１が検出する温度に代えて、体感温度センサが検出する温度を設定温度に近づける空調運転を行う。 In addition, during normal operation, the indoor unit control unit 53 performs air conditioning operation so that the air temperature near the intake port of the indoor heat exchanger 25 reaches the set temperature, but in the concentrated mode, the air conditioning operation may be performed so that the sensible temperature that a person actually feels approaches the set temperature, which is the target temperature. In this case, for example, in the configuration of FIG. 1, a sensible temperature sensor that detects the sensible temperature of the user HM is placed adjacent to the infrared sensor 44, and in step S103 of FIG. 6, air conditioning operation is performed to bring the temperature detected by the sensible temperature sensor, instead of the temperature detected by the temperature sensor 41, closer to the set temperature.
　また、赤外線センサ４４がユーザＨＭを検出した場合、集中モードの空調運転を行い、赤外線センサ４４が、ユーザＨＭを検出しなくなった場合、集中モードの空調運転を中止してもよい。 In addition, if the infrared sensor 44 detects the user HM, the air conditioning operation in the intensive mode may be performed, and if the infrared sensor 44 no longer detects the user HM, the air conditioning operation in the intensive mode may be stopped.
　実施の形態１では、室内機制御部５３は、リモコン５５からのユーザＨＭの指示を受信していたが、本開示はこれに限られない。室内機制御部５３は、空気調和装置２用のアプリケーションがインストールされた情報機器９０からのユーザＨＭの指示を受信してもよい。 In the first embodiment, the indoor unit control unit 53 receives instructions from the user HM from the remote control 55, but the present disclosure is not limited to this. The indoor unit control unit 53 may receive instructions from the user HM from an information device 90 in which an application for the air conditioning device 2 is installed.
　（実施の形態２）
　実施の形態１においては、集中度向上制御処理の対象となるユーザＨＭは一人である例を示した。本開示は、これに限定されず、図１４に例示するように、制御部５３ａは、複数人のユーザＨＭを対象とした集中度向上制御処理を行ってもよい。
　ユーザＨＭが複数人の場合、生体情報検出装置４３は各ユーザＨＭの脈波を検出し、各ユーザＨＭの集中度ＣＲを特定する。また、赤外線センサ４４は、複数人の位置を特定する。図１４では、制御部５３ａは、２人のユーザＨＭ１とＨＭ２を対象とした集中度向上制御処理を行うが、２人に限らず任意の複数人を対象としてもよい。以下、図６のフローチャートを参照しつつ、実施の形態１と異なる点を中心に説明する。なお、図１４は、空気調和システム１が天井設置型の例である。 (Embodiment 2)
In the first embodiment, an example has been shown in which the concentration level improvement control process is performed on one user HM. The present disclosure is not limited to this, and as illustrated in FIG. 14, the control unit 53a may perform the concentration level improvement control process on a plurality of users HM.
When there are multiple users HM, the bioinformation detection device 43 detects the pulse waves of each user HM and identifies the concentration level CR of each user HM. The infrared sensor 44 also identifies the positions of the multiple people. In FIG. 14, the control unit 53a performs a concentration level improvement control process for two users HM1 and HM2, but the process may be performed for any multiple people, not limited to two people. Below, the differences from the first embodiment will be mainly described with reference to the flowchart in FIG. 6. Note that FIG. 14 shows an example in which the air conditioning system 1 is installed on the ceiling.
　実施の形態２では、制御部５３ａは、集中度向上制御処理において、２人のユーザＨＭ１とＨＭ２の集中度ＣＲ１とＣＲ２を取得する（ステップＳ１０１）。続いて、制御部５３ａは、判定処理では、２人のユーザＨＭ１とＨＭ２の集中度ＣＲ１tとＣＲ２tの平均値ＡＶＣＲt＝（ＣＲ１f＋ＣＲ２f）／２と、前回の平均値ＡＶＣＲt-1＝（ＣＲ１f-1＋ＣＲ２f-1）／２との差分ＣＢtを求める。制御部５３ａは、今回の平均値ＡＶＣＲtが前回の平均値ＡＶＣＲt-1よりも低下し、且つ、差分ＣＢtの絶対値は判定閾値Ｔｈａ以上であるか否かを判定する（ステップＳ１０２）。制御部５３ａは、ステップＳ１０５の処理についても、ステップＳ１０１と同様に行う。また、ステップＳ１０６の処理では、制御部５３ａは、２人のユーザＨＭ１とＨＭ２の集中度ＣＲ１tとＣＲ２tの平均値ＡＶＣＲt＝（ＣＲ１f＋ＣＲ２f）／２が、判定閾値Ｔｈｂ以上であるか否かを判定する（ステップＳ１０６）。 In the second embodiment, the control unit 53a obtains the concentration levels CR1 and CR2 of the two users HM1 and HM2 in the concentration level improvement control process (step S101). Next, in the judgment process, the control unit 53a obtains the difference CBt between the average value AVCRt = ( CR1f + CR2f ) / 2 of the concentration levels CR1t and CR2t of the two users HM1 and HM2 and the previous average value AVCRt -1 = (CR1f -1 + CR2f -1 ) / 2. The control unit 53a judges whether the current average value AVCRt is lower than the previous average value AVCRt -1 and whether the absolute value of the difference CBt is equal to or greater than the judgment threshold value Tha (step S102). The control unit 53a also performs the process of step S105 in the same manner as step S101. Furthermore, in the process of step S106, the control unit 53a determines whether the average value AVCR t = (CR1 f + CR2 f )/2 of the concentration levels CR1 t and CR2 t of the two users HM1 and HM2 is equal to or greater than the determination threshold Thb (step S106).
　制御部５３ａは、集中度向上運転実行の際、温度、湿度、風量、風向を、平均集中度ＡＶＣＲに基づいて、２人のユーザＨＭ１とＨＭ２に共通に制御する。一方、制御部５３ａは、風向については、ベーン３４を制御して、２つの風流Ｆ１、Ｆ２を生成し、２人のユーザＨＭ１，ＨＭ２に個別に制御する。これにより、例えば、図１４に示すように、実線で示す風向きＦ１，Ｆ２から破線で示す風向きＦ１’，Ｆ２’に制御して風あて制御を行うことができる。これにより、ユーザＨＭ毎に集中度ＣＲを向上し得る。 When performing the concentration improvement operation, the control unit 53a controls the temperature, humidity, air volume, and wind direction for both users HM1 and HM2 based on the average concentration AVCR. On the other hand, the control unit 53a controls the wind direction by controlling the vanes 34 to generate two air currents F1 and F2, which are individually controlled for the two users HM1 and HM2. This makes it possible to control the wind direction from the wind directions F1 and F2 shown by solid lines to the wind directions F1' and F2' shown by dashed lines, for example, as shown in FIG. 14. This makes it possible to improve the concentration CR for each user HM.
　（実施の形態２の変形例）
　実施の形態２では、判定処理（ステップＳ１０２）において、２人の集中度ＣＲの平均値ＡＶＣＲの差分の絶対値と、判定閾値Ｔｈａとを比較することにより、集中度向上運転を行うか否かを判定した。また、判定処理（ステップＳ１０６）において、２人の集中度ＣＲの平均値ＡＶＣＲと、判定閾値Ｔｈｂとを比較することにより、集中度向上運転を継続するか否かを判定した。本開示はこれらに限られない。例えば、複数のユーザＨＭの集中度ＣＲの中間値、最小値、最大値、等の任意の代表値と判定閾値とを比較、または、かかる代表値の差分の絶対値と判定閾値とを比較して、実施するか否か又は継続するか否かを判定してもよい。 (Modification of the second embodiment)
In the second embodiment, in the judgment process (step S102), the absolute value of the difference between the average value AVCR of the concentration levels CR of the two people is compared with the judgment threshold value Tha to judge whether or not to perform the concentration level improvement operation. Also, in the judgment process (step S106), the average value AVCR of the concentration levels CR of the two people is compared with the judgment threshold value Thb to judge whether or not to continue the concentration level improvement operation. The present disclosure is not limited to these. For example, any representative value such as the median value, minimum value, maximum value, etc. of the concentration levels CR of multiple users HM may be compared with the judgment threshold value, or the absolute value of the difference between such representative values may be compared with the judgment threshold value to judge whether or not to perform or continue the operation.
　また、実施の形態１，２では、制御部５３ａは、ユーザＨＭの集中度ＣＲが低下し且つ集中度ＣＲの差分の絶対値が判定閾値Ｔｈａ以上であるか否かを判定し（ステップＳ１０２）、ユーザＨＭの集中度ＣＲが低下し且つ集中度ＣＲの差分の絶対値が判定閾値Ｔｈａ以上であるとき（ステップＳ１０２：Ｙｅｓ）にのみ集中度向上運転を行うように説明していたが、本開示はこれに限られない。集中モードが指定されたときには、無条件に、制御部５３ａは、集中度向上運転を開始するようにしてもよい。 In addition, in the first and second embodiments, the control unit 53a determines whether the concentration level CR of the user HM has decreased and the absolute value of the difference in the concentration level CR is equal to or greater than the judgment threshold value Tha (step S102), and performs the concentration improvement operation only when the concentration level CR of the user HM has decreased and the absolute value of the difference in the concentration level CR is equal to or greater than the judgment threshold value Tha (step S102: Yes), but the present disclosure is not limited to this. When the concentration mode is specified, the control unit 53a may unconditionally start the concentration improvement operation.
　実施の形態１，２で、赤外線センサ４４が、ユーザＨＭの存在・不存在、複数人の位置を特定していたが、これに代えて、ドップラーセンサが複数人の位置を特定してもよい。具体的には、ドップラーセンサが照射角度を変えながら照射し、人の位置を特定する。 In the first and second embodiments, the infrared sensor 44 identifies the presence or absence of the user HM and the positions of multiple people, but instead, a Doppler sensor may identify the positions of multiple people. Specifically, the Doppler sensor irradiates light while changing the irradiation angle to identify the positions of people.
　実施の形態１，２において、室内空間７１は、室内に限らず、閉空間でも、一部が開口した半閉空間でもかまわない。また、エアカーテンなどで区切られた、実質的な閉空間、半閉空間などでもよい。 In the first and second embodiments, the indoor space 71 is not limited to a room, but may be a closed space or a semi-closed space with a portion open. It may also be a substantially closed space or a semi-closed space separated by an air curtain or the like.
（実施の形態３）
　実施の形態１，２では、集中度ＣＲを脈波に基づいて求めた。この開示はこれに限定されない。集中度ＣＲの精度を向上するため、他の生体情報を併用してもよい。例えば、ユーザＨＭの脈波とその変化、ユーザＨＭの心拍数とその変化、ユーザＨＭの脳波とその変化、ユーザＨＭの体温とその変化、ユーザＨＭの表情筋の動きの変化、ユーザＨＭの振る舞い、等をセンサで測定し、測定値からそれぞれ集中度ＣＲを求め、求められた複数の集中度ＣＲを重み付け平均して、制御に使用する集中度ＣＲを求めてもよい。 (Embodiment 3)
In the first and second embodiments, the concentration level CR is calculated based on the pulse wave. This disclosure is not limited to this. In order to improve the accuracy of the concentration level CR, other biological information may be used in combination. For example, the pulse wave of the user HM and its changes, the heart rate of the user HM and its changes, the brain waves of the user HM and its changes, the body temperature of the user HM and its changes, the changes in the movement of the facial muscles of the user HM, the behavior of the user HM, etc. may be measured by a sensor, the concentration level CR may be calculated from each measurement value, and the concentration level CR to be used for control may be calculated by taking a weighted average of the calculated concentration levels CR.
　また、集中度ＣＲの測定に、ニューラルネットワークなどのＡＩ（Artificial Intelligence）を活用することも可能である。この場合、例えば、ユーザＨＭの脈波とその変化、ユーザＨＭの心拍数とその変化、ユーザＨＭの脳波とその変化、ユーザＨＭの体温とその変化、ユーザＨＭの表情筋の動きの変化、ユーザＨＭの振る舞い、等の入力データのセットと出力である集中度ＣＲとの関係を予め調査して、教師データを作成する。次に、ＡＩ装置に教師データを学習させる。ＡＩ装置は、センサで測定された脈波、脳波などの生体情報、その変化率、その履歴等、を入力し、集中度ＣＲを示す指標を出力する。 It is also possible to use AI (Artificial Intelligence) such as neural networks to measure the concentration level CR. In this case, teacher data is created by investigating in advance the relationship between a set of input data, such as the user HM's pulse waves and their changes, the user HM's heart rate and its changes, the user HM's brain waves and its changes, the user HM's body temperature and its changes, changes in the movement of the user HM's facial muscles, the user HM's behavior, etc., and the output concentration level CR. Next, the AI device is made to learn the teacher data. The AI device inputs biometric information such as pulse waves and brain waves measured by a sensor, their rate of change, their history, etc., and outputs an index showing the concentration level CR.
　また、実施の形態１，２では、ステップＳ１０２で、予め設定された基準と集中度ＣＲとの関係から、集中度向上運転を行うか否かを判別したが、判定なしで、集中度向上運転を行ってもよい。例えば、室内機制御部５３にＡＩ技術を活用し、例えば、集中度ＣＲ、その変化、変化率又はその履歴をＡＩ装置に入力し、ＡＩ装置が適切な制御態様を出力するように構成してもよい。この場合、例えば、集中度ＣＲ、その変化量又は変化率、これらの履歴と、制御対象と制御内容とその効果との関係を予め調査して、教師データを作成する。次に、ＡＩ装置に教師データを学習させる。ＡＩ装置は、図６のステップＳ１０２で、生体情報検出装置４３から供給された集中度ＣＲ等入力し、適切な制御対象と制御内容とを出力する。続いて、ステップＳ１０３で、出力された制御対象と制御内容で示される空調制御を行う。 In addition, in the first and second embodiments, in step S102, it is determined whether or not to perform the concentration improvement operation based on the relationship between the preset standard and the concentration level CR, but the concentration improvement operation may be performed without making a determination. For example, AI technology may be utilized in the indoor unit control unit 53, and, for example, the concentration level CR, its change, change rate, or its history may be input to the AI device, and the AI device may output an appropriate control mode. In this case, for example, the concentration level CR, its change amount or change rate, and the history of these, as well as the relationship between the control target, the control content, and its effect are investigated in advance to create teacher data. Next, the AI device is made to learn the teacher data. In step S102 of FIG. 6, the AI device inputs the concentration level CR etc. supplied from the bioinformation detection device 43, and outputs the appropriate control target and control content. Next, in step S103, air conditioning control indicated by the output control target and control content is performed.
　本開示は、本開示の広義の精神と範囲を逸脱することなく、様々な実施の形態及び変形が可能とされるものである。また、上述した実施の形態は、本開示を説明するためのものであり、本開示の範囲を限定するものではない。つまり、本開示の範囲は、実施の形態ではなく、請求の範囲によって示される。そして、請求の範囲内及びそれと同等の開示の意義の範囲内で施される様々な変形が、本開示の範囲内とみなされる。 This disclosure allows for various embodiments and modifications without departing from the broad spirit and scope of the disclosure. Furthermore, the above-described embodiments are intended to explain the disclosure and do not limit the scope of the disclosure. In other words, the scope of the disclosure is indicated by the claims, not the embodiments. Furthermore, various modifications made within the scope of the claims and within the scope of the disclosure equivalent thereto are considered to be within the scope of the disclosure.
