　本発明は、室内の空調を行う空気調和装置の制御システムに関する。 The present invention relates to a control system for an air conditioner that air-conditions a room.
　従来、オフィス、学校または学習塾で作業効率が室内環境によって左右される研究事例があった。そこで、室内へ刺激付与物質を供給し、刺激付与物質の供給と除去とを切り替えて室内の温熱環境を変化させることにより、自律神経系の活性を高めるようにした技術がある（例えば、特許文献１参照）。 In the past, there were research cases where work efficiency was affected by the indoor environment in offices, schools, or cram schools. Therefore, there is a technique of supplying an stimulating substance to the room and switching the supply and the removal of the stimulating substance to change the indoor thermal environment to enhance the activity of the autonomic nervous system (for example, Patent Document 1).

　特許文献１では、自律神経系の活性を高めることを目的として、刺激付与物質の供給により在室者に温熱刺激を与えている。このように、温熱刺激は自律神経系の活性を高めることができるが、在室者に快適感を与えることも可能である。しかし、特許文献１では、温熱刺激によって在室者に快適感を与えることについては検討されていない。また、在室者が快適に感じるかどうかは、在室者個人の活動量も影響すると考えられる。しかし、特許文献１ではこの点についても検討されていない。 In Patent Document 1, a thermal stimulus is given to a person in the room by supplying a stimulating substance for the purpose of enhancing the activity of the autonomic nervous system. As described above, the thermal stimulus can enhance the activity of the autonomic nervous system, but can also give the occupant a feeling of comfort. However, Patent Document 1 does not consider giving a feeling of comfort to a person in the room by thermal stimulation. In addition, whether or not the occupants feel comfortable can be influenced by the activity amount of each occupant. However, Patent Document 1 does not consider this point either.
　本発明はこのような点を鑑みなされたもので、在室者の活動量を考慮しつつ、温熱刺激により快適性の向上を図ることが可能な空気調和装置の制御システムを提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object thereof is to provide a control system of an air conditioner capable of improving comfort by thermal stimulation while considering the activity amount of a person in the room.

The control device includes a sensor and a control device that operates in a fluctuation mode in which the target temperature fluctuates, and the control device, in accordance with the activity amount measured by the activity amount sensor, has a fluctuation width that is a fluctuation range of the target temperature in the fluctuation mode. One or both of the fluctuation cycle, which is the fluctuation cycle of the target temperature, is changed.

(Structure of Embodiment 1)
FIG. 1 is a diagram showing an example of an air conditioning system according to Embodiment 1 of the present invention.
The air conditioning system includes an air conditioning device 10 that performs air conditioning so that the room temperature of the air-conditioned space reaches a target temperature, and a control system 50 that controls the air conditioning device 10.
　空気調和装置１０は、室内機２０と室外機３０とを備えている。室内機２０は、室内送風機２１と、室内熱交換器２２と、室温を計測する室温センサ２３とを備えている。室内機２０は、冷房、暖房、除湿、加湿、保湿または送風などの運転モードにて室内を空調する。 The air conditioner 10 includes an indoor unit 20 and an outdoor unit 30. The indoor unit 20 includes an indoor blower 21, an indoor heat exchanger 22, and a room temperature sensor 23 that measures a room temperature. The indoor unit 20 air-conditions the room in operation modes such as cooling, heating, dehumidifying, humidifying, moisturizing, or blowing air.
　室外機３０は、室外送風機３１、室外熱交換器３２、膨張弁３３、四方弁３４および圧縮機３５を備える。圧縮機３５、四方弁３４、室外熱交換器３２、膨張弁３３および室内熱交換器２２が冷媒配管４０で接続されることで、冷媒回路が構成されている。そして、冷媒回路の内部を冷媒が圧縮と膨張を繰り返しながら循環することで、ヒートポンプが形成されている。 The outdoor unit 30 includes an outdoor blower 31, an outdoor heat exchanger 32, an expansion valve 33, a four-way valve 34, and a compressor 35. A refrigerant circuit is configured by connecting the compressor 35, the four-way valve 34, the outdoor heat exchanger 32, the expansion valve 33, and the indoor heat exchanger 22 with the refrigerant pipe 40. The heat pump is formed by circulating the refrigerant in the refrigerant circuit while repeatedly compressing and expanding.
　制御システム５０は、空調空間の在室者の活動量を計測する活動量センサ６０と、空気調和システム全体を制御する制御装置７０とを備えている。 The control system 50 includes an activity amount sensor 60 that measures the activity amount of a person in the air-conditioned space, and a control device 70 that controls the entire air conditioning system.
　活動量センサ６０は、たとえば、赤外線センサまたはウェアラブルセンサなどで構成される。活動量センサ６０が赤外線センサで構成される場合、室内の熱分布から、在室者が立っている、座っている、または動いているなどの状態を取得して、活動量を算出する。また、活動量センサ６０がウェアラブルセンサとして例えば手首に取り付けられる時計式タイプのものである場合、加速度計などが内蔵されて活動量計としての機能を有するものを用いればよい。そして、活動量センサ６０で計測された活動量は通信で制御装置７０に送られる。 The activity amount sensor 60 is composed of, for example, an infrared sensor or a wearable sensor. When the activity amount sensor 60 is composed of an infrared sensor, the activity amount is calculated by acquiring the state such as the standing person, sitting or moving from the indoor heat distribution. Further, when the activity amount sensor 60 is a wearable sensor of, for example, a timepiece type that is attached to the wrist, an accelerometer or the like may be incorporated to have a function as an activity amount sensor. Then, the activity amount measured by the activity amount sensor 60 is sent to the control device 70 by communication.
　活動量は、具体的には代謝量［ｍｅｔ］である。代謝量１［ｍｅｔ］は、体表面１［ｍ２］当たり５８．２［Ｗ］の熱量を表す。この熱量［Ｗ］は、日本人の平均的な体表面１．７［ｍ２］の場合である。代謝量は、安静時から運動時まで１０倍以上と大きく変化する。例えば、安静時は１．０［ｍｅｔ］である。立位時は１．２［ｍｅｔ］である。ゆっくり歩く場合は２．０［ｍｅｔ］である。すこし早く歩く場合は３．０［ｍｅｔ］である。マラソン時速１０キロは１０［ｍｅｔ］程度である（出典：空気調和・衛生工学会「快適な温熱環境のメカニズム」）。 The activity amount is specifically a metabolic amount [met]. The metabolism amount 1 [met] represents a heat amount of 58.2 [W] per body surface 1 [m 2 ]. This amount of heat [W] is for an average Japanese body surface of 1.7 [m 2 ]. The amount of metabolism greatly changes from resting to exercising, 10 times or more. For example, it is 1.0 [met] at rest. It is 1.2 [met] when standing. When walking slowly, it is 2.0 [met]. If you walk a little faster, it is 3.0 [met]. A marathon speed of 10 km / h is about 10 [met] (Source: Air Conditioning and Sanitary Engineering Society "Mechanism of comfortable thermal environment").

（温熱刺激と快適性との関係）
　今までの研究結果では、生体リズムで空調を運転制御するという概念、例えば１／ｆゆらぎの運転制御が、生体に対し快適感を与える可能性があることが分かった。本実施の形態１では、この種のゆらぎモードを室温調整に採用し、在室者の快適性の向上を図る。なお、本実施の形態１のゆらぎモードは、１／ｆゆらぎとは異なるゆらぎモードであり、以下に説明する。 (Relationship between thermal stimulation and comfort)
From the research results to date, it has been found that the concept of controlling the operation of the air conditioning by the biorhythm, for example, the operation control of 1 / f fluctuation, may give the living body a comfortable feeling. In the first embodiment, this type of fluctuation mode is adopted for room temperature adjustment to improve the comfort of the person in the room. The fluctuation mode of the first embodiment is a fluctuation mode different from 1 / f fluctuation and will be described below.
（ゆらぎモード）
　ゆらぎモードでは、活動量センサ６０で計測された在室者の活動量に応じて、空気調和装置１０の目標温度のゆらぎ幅およびゆらぎ周期を自動的に調整する。ゆらぎ幅とは、目標温度の変動幅である。ゆらぎ周期は目標温度の変動周期である。以下、図３を参照してゆらぎモードについてさらに具体的に説明する。なお、以下では冷房運転時のゆらぎモードについて説明する。 (Fluctuation mode)
In the fluctuation mode, the fluctuation width and fluctuation cycle of the target temperature of the air conditioner 10 are automatically adjusted according to the activity amount of the person in the room measured by the activity amount sensor 60. The fluctuation width is the fluctuation width of the target temperature. The fluctuation cycle is a fluctuation cycle of the target temperature. Hereinafter, the fluctuation mode will be described more specifically with reference to FIG. The fluctuation mode during the cooling operation will be described below.
　図３は、本発明の実施の形態１に係る空気調和システムのゆらぎモードにおける活動量に応じた目標温度のゆらぎ幅とゆらぎ周期とをまとめた表を示す図である。
　本実施の形態１では、活動量をＡ～Ｃの閾値によって４つの範囲に分ける。具体的には、「安静」において活動量は０［ｍｅｔ］≦活動量＜１［ｍｅｔ］となる。また、「軽い運動」において活動量は１［ｍｅｔ］≦活動量＜３［ｍｅｔ］となる。また、「適度な運動」において活動量は３［ｍｅｔ］≦活動量＜５［ｍｅｔ］となる。「ヘビーな運動」において活動量は５［ｍｅｔ］≦活動量となる。なお、この分け方は一例であって、この分け方に限定されるものではない。 FIG. 3 is a diagram showing a table summarizing the fluctuation width and fluctuation cycle of the target temperature according to the amount of activity in the fluctuation mode of the air conditioning system according to Embodiment 1 of the present invention.
In the first embodiment, the activity amount is divided into four ranges according to the threshold values A to C. Specifically, the activity amount in “rest” is 0 [met] ≦ activity amount <1 [met]. In the “light exercise”, the activity amount is 1 [met] ≦ activity amount <3 [met]. In the “moderate exercise”, the activity amount is 3 [met] ≦ activity amount <5 [met]. In the “heavy exercise”, the activity amount is 5 [met] ≦ activity amount. Note that this division method is an example, and the present invention is not limited to this division method.
　活動量が大きくなるほど、人体の温熱敏感度が高くなる。逆に、睡眠中など代謝量が小さくなった時、人体の温熱敏感度もそれに応じて低下する。よって、ゆらぎモードでは、図３に示すように、活動量が大きくなるに連れて、ゆらぎ幅をＨ１＜Ｈ２＜Ｈ３のように大きくする一方、ゆらぎ周期をΔＴ１＞ΔＴ２＞ΔＴ３のように短くする。なお、図３に示したゆらぎ幅およびゆらぎ周期の具体的数値は一例を示したに過ぎず、それらは実使用条件などに応じて適宜設定すれば良い。 The greater the amount of activity, the higher the temperature sensitivity of the human body. On the contrary, when the metabolic rate becomes small, such as during sleep, the thermal sensitivity of the human body also decreases accordingly. Therefore, in the fluctuation mode, as shown in FIG. 3, the fluctuation width is increased as H1 <H2 <H3 and the fluctuation cycle is shortened as ΔT1> ΔT2> ΔT3 as the amount of activity increases. .. Note that the specific values of the fluctuation width and fluctuation period shown in FIG. 3 are merely examples, and they may be set appropriately according to the actual use conditions.
　活動量センサ６０で検知された活動量が「安静」の範囲にあるときは、目標温度の変動は行わず、室温が、以下に説明する初期値を維持するように制御する。そして、活動量センサ６０で検知された活動量が例えば「適度な運動」の範囲にあるときは、図３の具体例で説明すると、ゆらぎ幅をＨ２にするとともに、ゆらぎ周期をΔＴ２とする。すなわち、ここでは冷房運転であるので、目標温度を初期値と初期値からＨ２低い温度とにΔＴ２毎に変動させる制御を行う。 When the activity amount detected by the activity amount sensor 60 is in the "rest" range, the target temperature is not changed, and the room temperature is controlled so as to maintain the initial value described below. Then, when the activity amount detected by the activity amount sensor 60 is in the range of, for example, “moderate exercise”, the fluctuation width is set to H2 and the fluctuation cycle is set to ΔT2, as described in the specific example of FIG. That is, since the cooling operation is performed here, control is performed to change the target temperature to an initial value and a temperature lower than the initial value by H2 for each ΔT2.
　また、本実施の形態１のゆらぎモードでは、在室者の快適性を維持しつつ、消費電力の低減を図る制御も併せて行う。具体的には、活動量が例えば「適度な運動」の範囲にあるとき、目標温度を初期値からＨ２低い温度に一定にするのではなく、初期値と初期値からＨ２低い温度とに交互に変動させる。これにより、目標温度を初期値からＨ２低い温度に一定にする場合に比べて消費電力の低減を図ることができる。 In addition, in the fluctuation mode of the first embodiment, control is also performed to reduce the power consumption while maintaining the comfort of the person in the room. Specifically, when the amount of activity is in the range of, for example, "moderate exercise", the target temperature is not kept constant at a temperature lower than the initial value by H2, but is alternately changed between the initial value and the temperature lower by H2 from the initial value. Fluctuate. As a result, power consumption can be reduced as compared with the case where the target temperature is fixed at a temperature lower than the initial value by H2.
　ここで、活動量に応じた目標温度のゆらぎ幅の決定方法について説明する。目標温度のゆらぎ幅は、例えば快適性を示す熱環境評価指数であるＰＭＶ（Ｐｒｅｄｉｃｔ　Ｍｅａｎ　Ｖｏｔｅ）を用いて決定する。ＰＭＶは、０が快適性の中立値であり、＋側を暖かい側に、－側を寒い側として評価可能な指数である。ＰＭＶが±０．５の範囲内であれば快適な環境である。ＰＭＶは、人間の温冷感に影響を与える複数のパラメータを用いて以下の（１）式で表される。 Here, the method of determining the fluctuation range of the target temperature according to the activity amount will be explained. The fluctuation range of the target temperature is determined by using, for example, PMV (Predict Mean Vote) which is a thermal environment evaluation index indicating comfort. PMV is an index that can be evaluated with 0 being the neutral comfort value, the + side being the warm side and the − side being the cold side. If the PMV is within ± 0.5, the environment is comfortable. PMV is expressed by the following equation (1) using a plurality of parameters that affect the human thermal sensation.
　ＰＭＶ＝ｆ（Ｔ、ＲＨ、ｖ、ＭＲＴ、ＭＥＴ、ｃｌｏ）・・・（１）
　ここで、
　Ｔ［℃］：室温
　ＲＨＡ［％］：相対湿度
　ｖ［ｍ／ｓ］：風速
　ＭＲＴ［℃］：平均放射温度
　ＭＥＴ［ｍｅｔ］：代謝量
　ｃｌｏ［ｃｌｏ］：着衣量 PMV = f (T, RH, v, MRT, MET, clo) ... (1)
here,
T [° C]: Room temperature RHA [%]: Relative humidity v [m / s]: Wind speed MRT [° C]: Average radiation temperature MET [met]: Metabolism amount Clo [clo]: Clothing amount
　上記の６つの変数のうち、室温Ｔと代謝量ＭＥＴ以外は固定値である。相対湿度ＲＨ、風速ｖおよび平均輻射温度ＭＲＴには、冷房時のデフォルト値として用意した値を用いるなどとすればよい。ここで、平均放射温度とは、周囲の全方向から受ける熱放射を平均化した温度である。 Of the above 6 variables, all values are fixed except room temperature T and metabolic rate MET. For the relative humidity RH, the wind speed v, and the average radiation temperature MRT, values prepared as default values during cooling may be used. Here, the average radiation temperature is a temperature obtained by averaging the heat radiation received from all the surrounding directions.
　（１）式の代謝量ＭＥＴに、「安静」時の活動量を示す代謝量、具体的には「安静」の活動量範囲のたとえば中心値を代入するとともに、ＰＭＶに快適性の中立値である０を代入し、室温Ｔを算出する。このようにして算出された室温Ｔは、在室者が「安静」の状態にあるときに快適と感じる温度である。この温度を初期値として用いる。 The metabolic rate MET of the equation (1) is substituted with the metabolic rate indicating the activity level at "rest", specifically, the central value of the activity range of "rest", and PMV is set to the neutral value of comfort. Substitute a certain 0 and calculate the room temperature T. The room temperature T calculated in this way is a temperature at which the person in the room feels comfortable when in a "rest" state. This temperature is used as an initial value.
　そして、（１）式の代謝量ＭＥＴに、「軽い運動」、「適度な運動」および「ヘビーな運動」のそれぞれの活動量範囲の中心値を代入して、それぞれの活動量に応じた快適な室温を算出する。その算出された室温と初期値との温度差が、活動量に応じたゆらぎ幅となる。 Then, by substituting the central values of the activity amount ranges of "light exercise", "moderate exercise" and "heavy exercise" into the metabolic rate MET of the equation (1), comfort according to each activity amount is obtained. Calculate the room temperature. The temperature difference between the calculated room temperature and the initial value becomes the fluctuation width according to the activity amount.
　図４は、本発明の実施の形態１に係る空気調和システムにおけるゆらぎモードの制御フローチャートの一例を示す図である。制御装置７０は、図４の処理を、ゆらぎモードの終了が指示されるまで予め設定された制御間隔、例えば１分毎に行う。
　冷房運転でゆらぎモードが選択されると、制御装置７０は、活動量センサ６０で計測された活動量を取得し（ステップＳ１）、活動量が予め分けられた４つの範囲のうち、どの範囲内であるのかをチェックする（ステップＳ２）。そして、該当する範囲に応じた空調制御を行う（ステップＳ３～ステップＳ１０）。 FIG. 4 is a diagram showing an example of a control flowchart of the fluctuation mode in the air conditioning system according to Embodiment 1 of the present invention. The control device 70 performs the process of FIG. 4 at a preset control interval, for example, every 1 minute until the end of the fluctuation mode is instructed.
When the fluctuation mode is selected in the cooling operation, the control device 70 acquires the activity amount measured by the activity sensor 60 (step S1), and which of the four ranges in which the activity amount is divided in advance Is checked (step S2). Then, air conditioning control is performed according to the applicable range (steps S3 to S10).
　すなわち、活動量センサ６０で計測された活動量が０［ｍｅｔ］≦活動量＜Ａ［ｍｅｔ］の範囲内である場合（ステップＳ３）、制御装置７０は目標室温を初期値に一定に保つ空調制御を行う（ステップＳ４）。具体的には、制御装置７０の周波数決定部７１は、室温センサ２３で計測された室温と初期値との温度差に応じて圧縮機３５の周波数を決定し、決定した周波数に基づき動作制御部７２が圧縮機３５を制御する。 That is, when the activity amount measured by the activity amount sensor 60 is within the range of 0 [met] ≦ activity amount <A [met] (step S3), the control device 70 keeps the target room temperature constant at the initial value. Control is performed (step S4). Specifically, the frequency determination unit 71 of the control device 70 determines the frequency of the compressor 35 according to the temperature difference between the room temperature measured by the room temperature sensor 23 and the initial value, and the operation control unit based on the determined frequency. 72 controls the compressor 35.
　活動量センサ６０で計測された活動量がＡ［ｍｅｔ］≦活動量＜Ｂ［ｍｅｔ］の範囲にある場合（ステップＳ５）、制御装置７０は、目標室温を、初期値と初期値よりもＨ１低い温度とにΔＴ１毎に変動する空調制御を行う（ステップＳ６）。活動量センサ６０で計測された活動量がＢ［ｍｅｔ］≦活動量＜Ｃ［ｍｅｔ］の範囲にある場合（ステップＳ７）、制御装置７０は、目標室温を、初期値と初期値よりもＨ２低い温度とにΔＴ２毎に変動する空調制御を行う（ステップＳ８）。活動量センサ６０で計測された活動量がＣ以上である場合（ステップＳ９）、制御装置７０は、目標室温を、初期値と初期値よりもＨ３低い温度とにΔＴ３毎に変動する空調制御を行う（ステップＳ１０）。 When the activity amount measured by the activity amount sensor 60 is within the range of A [met] ≦ activity amount <B [met] (step S5), the control device 70 sets the target room temperature to H1 rather than the initial value and the initial value. Air-conditioning control is performed such that the temperature changes to a low temperature every ΔT1 (step S6). When the activity amount measured by the activity amount sensor 60 is in the range of B [met] ≦ activity amount <C [met] (step S7), the control device 70 sets the target room temperature to H2 rather than the initial value and the initial value. Air-conditioning control is performed such that the temperature changes to a low temperature every ΔT2 (step S8). When the amount of activity measured by the amount-of-activity sensor 60 is C or more (step S9), the control device 70 performs the air conditioning control that changes the target room temperature to the initial value and the temperature H3 lower than the initial value for each ΔT3. Perform (step S10).
　図５は、本発明の実施の形態１に係る空気調和システムにおけるゆらぎモード時の活動量に応じた目標温度のゆらぎの一例を示した図である。以下、図３に示した具体的数値を用いてゆらぎモードを説明する。ここでは初期値を２７℃とする。
　図５の例では、ゆらぎモード開始初期ｔ０では、活動量が「安静」の範囲であるが、時刻ｔ１、時刻ｔ２、時刻ｔ３と進むに連れ、活動量が、「軽い運動」、「適度な運動」、「ヘビーな運動」へと上昇している。このように活動量が上昇するに連れ、目標温度のゆらぎ幅が１℃、１．５℃、２℃と広がる一方、ゆらぎ周期が４分、３分、２分と短くなっている。そして、時刻ｔ４では、活動量が「ヘビーな運動」から「軽い運動」に下がったことに伴い、目標室温のゆらぎ幅が２℃から１℃に減少する一方、ゆらぎ周期が２分から４分に長くなっている。そして、ｔ５で再び活動量が「適度な運動」から「ヘビーな運動」に上昇し、これに伴い、目標室温のゆらぎ幅が１℃から２℃に増加する一方、ゆらぎ周期が４分から２分に短くなっている。 FIG. 5: is the figure which showed an example of the fluctuation of the target temperature according to the activity amount in the fluctuation mode in the air conditioning system which concerns on Embodiment 1 of this invention. Hereinafter, the fluctuation mode will be described using the specific numerical values shown in FIG. Here, the initial value is 27 ° C.
In the example of FIG. 5, the activity amount is in the range of “rest” at the initial stage t0 of the fluctuation mode, but the activity amount is “light exercise” or “moderate” as the time t1, the time t2, or the time t3 progresses. Exercise ”and“ heavy exercise ”. In this way, as the amount of activity increases, the fluctuation range of the target temperature spreads to 1 ° C, 1.5 ° C, and 2 ° C, while the fluctuation cycle shortens to 4 minutes, 3 minutes, and 2 minutes. Then, at time t4, the fluctuation range of the target room temperature decreases from 2 ° C. to 1 ° C. while the activity amount decreases from “heavy exercise” to “light exercise”, while the fluctuation cycle changes from 2 minutes to 4 minutes. It's getting longer. Then, at t5, the activity amount again increases from “moderate exercise” to “heavy exercise”, and the fluctuation width of the target room temperature increases from 1 ° C. to 2 ° C., while the fluctuation cycle changes from 4 minutes to 2 minutes. It's getting shorter.
　なお、時刻ｔ１から時刻ｔ２では、時刻ｔ１で「軽い運動」に応じたゆらぎ制御、つまり目標温度を２７℃から１℃減算した２６℃と初期値の２７℃とに４分間毎に変化させる制御が開始される。時刻ｔ１から４分の間は、目標温度を２６℃とした運転が行われる。次の４分では目標温度を初期値とした運転が行われる。しかし、この例では１分毎に活動量に応じたゆらぎ制御の変更が行われるため、目標温度を初期値とした運転を開始してから４分経過前の時刻ｔ２で活動量が「軽い運動」から「適度な運動」に変化している。この活動量の変化に伴い、４分経過前に「適度な運動」に応じたゆらぎ制御が開始されている。 From time t1 to time t2, fluctuation control according to “light exercise” at time t1, that is, control for changing the target temperature from 27 ° C. by 1 ° C. to 26 ° C. and the initial value of 27 ° C. every 4 minutes. Is started. From time t1 to 4 minutes, the operation is performed with the target temperature being 26 ° C. In the next 4 minutes, the operation is performed with the target temperature as the initial value. However, in this example, the fluctuation control is changed according to the activity amount every minute, so that the activity amount is “light exercise” at time t2 four minutes before the start of the operation with the target temperature as the initial value. Has changed from "to moderate exercise". Along with this change in activity amount, fluctuation control according to "moderate exercise" is started 4 minutes before.
　以上のように本実施の形態１によれば、活動量に応じて目標室温のゆらぎ幅とゆらぎ周期とを変動させるようにしたので、在室者の活動量に合わせて適切な温熱刺激を与えることができ、快適性を向上できる。 As described above, according to the first embodiment, since the fluctuation width and fluctuation cycle of the target room temperature are changed according to the activity amount, an appropriate thermal stimulation is given according to the activity amount of the person in the room. It is possible to improve comfort.
　また、本実施の形態１では、活動量に応じて目標室温を変動させるにあたり、初期値から活動量に応じたゆらぎ幅だけ低い温度に一定に制御するのではなく、初期値と初期値からゆらぎ幅だけ低い温度とに交互に変動させるようにした。これにより、目標温度を初期値からゆらぎ幅だけ低い温度に一定にする場合に比べて消費電力の低減を図ることができる。 Further, in the first embodiment, when the target room temperature is changed according to the activity amount, the temperature is not controlled to be constant from the initial value to a temperature lower by the fluctuation width according to the activity amount, but is fluctuated from the initial value and the initial value. The temperature was alternately changed to a temperature lower by a width. As a result, power consumption can be reduced as compared with the case where the target temperature is fixed at a temperature lower by the fluctuation width from the initial value.
　ゆらぎモードでは、活動量が大きくなるほど、ゆらぎ幅を大きくするようにした。また、ゆらぎモードでは、活動量が大きくなるほど、ゆらぎ周期を短くするようにした。このように、活動量に応じてゆらぎ幅とゆらぎ周期とを変動させることができる。 In fluctuation mode, the fluctuation width is increased as the amount of activity increases. In the fluctuation mode, the fluctuation cycle is shortened as the amount of activity increases. In this way, the fluctuation width and fluctuation cycle can be varied according to the amount of activity.
　また、本実施の形態１では、活動量が複数の範囲に分けられ、各範囲にゆらぎ幅とゆらぎ周期とが設定されており、複数の範囲のうち、活動量センサ６０で計測された活動量を含む範囲に設定されたゆらぎ幅とゆらぎ周期でゆらぎモードが行われるようにした。このように、活動量を複数の範囲に分け、各範囲に応じたゆらぎモードを実現できる。 Further, in the first embodiment, the activity amount is divided into a plurality of ranges, and the fluctuation width and the fluctuation cycle are set in each range, and the activity amount measured by the activity amount sensor 60 in the plurality of ranges. The fluctuation mode is now performed with the fluctuation width and fluctuation period set in the range including. In this way, the activity amount can be divided into a plurality of ranges, and the fluctuation mode according to each range can be realized.
　ゆらぎモードにおける初期値は、安静時の活動量を少なくとも含む複数のパラメータを用いて算出される熱環境評価指数ＰＭＶが０になるように決定されている。また、活動量を分けた複数の範囲のそれぞれのゆらぎ幅は、各範囲内の活動量を少なくとも含む複数のパラメータを用いて算出される熱環境評価指数ＰＭＶが０になるように決定された温度と、初期値との温度差である。このように、熱環境評価指数ＰＭＶが０になるように初期値およびゆらぎ幅を設定するため、熱環境評価指数ＰＭＶが快適となる室温での空調制御が行われることになり、より快適性を向上できる。 The initial value in the fluctuation mode is determined so that the thermal environment evaluation index PMV calculated using a plurality of parameters including at least the activity amount at rest becomes 0. Further, the fluctuation widths of each of the plurality of ranges into which the activity amount is divided are determined such that the thermal environment evaluation index PMV calculated using a plurality of parameters including at least the activity amount in each range is 0. And the temperature difference from the initial value. In this way, since the initial value and the fluctuation width are set so that the thermal environment evaluation index PMV becomes 0, the air conditioning control at room temperature at which the thermal environment evaluation index PMV becomes comfortable is performed, and the comfort is further improved. Can be improved.
　なお、本実施の形態１では、目標温度のゆらぎ幅とゆらぎ周期との両方を活動量に応じて変化させるようにしたが、どちらか一方を変動させるようにしてもよい。以下、具体的に説明する。 In the first embodiment, both the fluctuation width of the target temperature and the fluctuation cycle are changed according to the activity amount, but either one may be changed. The details will be described below.
　図６は、本発明の実施の形態１に係る空気調和システムにおけるゆらぎモードの変形例１の説明図である。
　図６の変形例では、目標温度のゆらぎ幅が一定で、ゆらぎ周期を活動量に応じて変化させている。 FIG. 6 is an explanatory diagram of variation 1 of the fluctuation mode in the air conditioning system according to Embodiment 1 of the present invention.
In the modification of FIG. 6, the fluctuation width of the target temperature is constant, and the fluctuation cycle is changed according to the activity amount.

In the modified example of FIG. 7, the fluctuation width of the target temperature is changed according to the amount of activity, and the fluctuation cycle is made constant.
　以上のように、目標温度のゆらぎ幅およびゆらぎ周期の一方を変動させる制御としても、快適性を向上できる。 As described above, comfort can be improved even by controlling one of the fluctuation width and fluctuation cycle of the target temperature.
　なお、本実施の形態１では、初期値およびゆらぎ幅を熱環境評価指数ＰＭＶを用いて決定したが、本発明はこれに限られない。初期値は例えばユーザにより設定された設定温度としてもよい。 In the first embodiment, the initial value and the fluctuation width are determined using the thermal environment evaluation index PMV, but the present invention is not limited to this. The initial value may be, for example, a set temperature set by the user.

In the heating operation, the fluctuation of the target room temperature may be changed to an initial value and a temperature higher than the initial value by a fluctuation width.
