- Embodiment 1 The air conditioner according to Embodiment 1 of the present disclosure controls operation based on the "tone entropy method". Specifically, the operation is controlled using the "tone value” and “entropy value” calculated based on the “tone entropy method”. Further, in Embodiment 2 described later, further, the distance between two points calculated using the "tone value” and the “entropy value” calculated based on the “tone entropy method” for each beat " The operation is controlled using the “movement amount”. Therefore, first, the "tone entropy method” will be explained here.
- FIG. 1 is a diagram showing an example of a heartbeat waveform.
- FIG. 2 is a diagram showing an example of PI frequency distribution.
- the "tone entropy method" as shown in FIG. 1, is a cardiac autonomic nerve activity measurement method based on the rate of change of the RR interval in a heartbeat waveform (electrocardiogram waveform), and is used in various fields. .
- an RR interval change rate PI Percentage Index
- a rate of change PI(n) from the n (integer) RR interval RRI(n) to the n+1 RR interval RRI(n+1) is calculated using equation (1).
- the PI calculated using Equation (1) is related to heart rate.
- a positive value of PI indicates an increase in heart rate.
- An increase in heart rate indicates that sympathetic nervous system activity predominates over parasympathetic nervous system activity.
- the PI is a negative value, it indicates that the heart rate is decreasing.
- a decrease in heart rate indicates that parasympathetic nervous system activity predominates over sympathetic nervous system activity.
- PI is measured for a certain period of time to calculate the tone value and the entropy value. That is, N (integer) PI values are obtained at a certain time. The obtained N PI values are classified into M (integer) classes. As a result, a PI histogram (PI frequency distribution) as shown in FIG. 2 is created. For example, class i ranges from 0 to 1%. In the PI frequency distribution shown in FIG. 2, the frequency of class i is fi.
- the tone value T is the average value of PI in the PI frequency distribution.
- the tone value T is calculated using Equation (2).
- the tone value T calculated using formula (2) indicates the balance between increases and decreases in the heart rate, and also indicates the balance in which the sympathetic nervous system and the parasympathetic nervous system are active.
- the entropy value E is an index that indicates the uniformity of the PI frequency distribution.
- the entropy value E is calculated using Equation (3).
- Equation (3) p(i) in formula (3) is the probability of occurrence of class i.
- the occurrence probability p(i) is calculated using Equation (4).
- fsum in formula (4) is the sum of the frequencies of all classes.
- the PI frequency distribution has a class close to the zero PI value (in the case of FIG. 2, classes i, i- The frequency of 1) takes a distribution (steep mountain-shaped distribution) that is significantly larger than the frequency of other classes. This indicates that the activity of the autonomic nerves is weak and the heart rate hardly changes.
- the entropy value E is a relatively large value
- the PI frequency distribution takes a distribution in which the frequency of each class is generally uniform. That is, the width of change in the RR interval is large, and the absolute value of the PI value is large. This indicates that the autonomic nerves are active and the heart rate fluctuates greatly. Therefore, the entropy value indicates the intensity of autonomic nerve activity.
- the movement amount D is calculated using the Pythagorean formula (5).
- expression (5) the "tone value T1" and “entropy value E1” calculated based on the “tone entropy method” for RRI(n) and RRI(n+1), RRI(n+1) and RRI(n+2)
- the amount of movement is the difference between the plot showing the combination of the tone value and entropy value at the (n-1)th beat and the plot showing the combination of the tone value and entropy value at the nth beat on the tone-entropy map. Corresponds to straight-line distance.
- the heart rate and pulse rate instead of the RR interval RRI in the heartbeat waveform necessary for calculating the tone value and the entropy value.
- the RR interval has a corresponding relationship with the heart rate and pulse rate. For example, if the RR interval is 1 second, the heart rate (per minute) is 60 because the ventricles of the heart are contracting once per second. Moreover, when there is no disease such as arrhythmia, the heart rate and the pulse rate are the same. Therefore, heart rate and pulse rate can be used to calculate tone and entropy values.
- FIG. 3 is a diagram showing a tone-entropy map in the present disclosure.
- the inventor of the present disclosure has found that the tone value T and the entropy value E correspond to the "thermal sensation" of the user of the air conditioner, as shown in FIG. Therefore, in the air conditioner of the present disclosure, operation control is performed using the tone value T and the entropy value E based on such tone entropy method.
- the findings newly discovered by the inventors will be described.
- thermo sensation refers to the user's bodily sensation of the surrounding environment temperature, such as heat, warmth, coolness, and coldness.
- FIG. 3 is a tone-entropy map in which one axis (vertical axis) represents the tone value T and the other axis (horizontal axis) represents the entropy value E.
- the inventor found a combination of the tone value and the entropy value corresponding to a comfortable feeling that is neither too hot nor too cold (for example, the feeling when being in a room with a room temperature of 18 to 28 degrees). It was found experimentally that That is, in the tone-entropy map, the existence of a comfortable region As where the user feels comfortable was found.
- the inventor experimentally determined the combination of the tone value and the entropy value corresponding to the sensation of being too hot and uncomfortable, that is, the discomfort region Ah (first discomfort region) in the tone-entropy map. I pinpointed it.
- the inventor experimentally determined the combination of the tone value and the entropy value corresponding to the feeling of being too cold and uncomfortable, that is, the discomfort area Ac (second discomfort area) in the tone-entropy map. I pinpointed it.
- the correspondence relationship between the combination of the tone value T and the entropy value E and the user's thermal sensation is obtained by placing a plurality of users (subjects) under a plurality of temperature environments with different temperatures, and comparing the tone values of the plurality of users. It is ascertained by measuring the entropy value E.
- FIG. 4 shows changes in tone value and entropy value under multiple temperature environments for one subject.
- FIG. 5 also shows converged tone values and entropy values under a plurality of temperature environments.
- the tone value T and the entropy value E under a temperature environment of 35 degrees, that is, an environment where the subject is too hot to feel uncomfortable, and a temperature environment of 2 degrees, that is, when the subject is cold.
- the tone value T and the entropy value E in an environment that is too uncomfortable have different distribution ranges in the tone-entropy map.
- the tone value T when it is too hot and uncomfortable (35 degrees) is concentrated in the range of 0 to -0.05%, while when it is too cold and uncomfortable (2 degrees), the tone value T is concentrated in the range of -0.25 to -0.4%.
- the entropy value E when it is too hot and uncomfortable (35 degrees) is concentrated in the range of 3 to 3.5, while the entropy value E when it is too cold and uncomfortable (2 degrees) are concentrated in the range of 4.5-5.
- the discomfort region Ah containing the combination of tone value and entropy value in a certain case has a high tone value and a low entropy value with respect to the discomfort region Ac containing the combination of tone value and entropy value when it is too cold to be uncomfortable. (weak). Therefore, based on the tone value T and the entropy value E, it is possible to distinguish whether the user is too hot to be uncomfortable or too cold to be uncomfortable.
- the combination of the tone value and the entropy value is the discomfort area Ah when it is too hot, and the discomfort area Ah when it is too cold. It is generally distributed between the discomfort area Ac of the case. Therefore, as shown in FIG. 3, in the tone-entropy map, the user's comfort area As is located between the discomfort area Ah and the discomfort area Ac.
- the air conditioner of the present disclosure Based on new knowledge obtained about the correspondence relationship between the tone-entropy map as described above, that is, the combination of the tone value and the entropy value and the user's thermal sensation, the air conditioner of the present disclosure: To control the operation of an air conditioner so that a user feels comfortable.
- the air conditioner of the present disclosure controls the operation of the air conditioner so that the user's tone value T and entropy value E are within the comfort area As. Also, when the tone value T and the entropy value E are in the discomfort region Ah or Ac, the user clearly feels uncomfortable because it is too hot or too cold and feels uncomfortable. .

（実施の形態１）
本開示の実施の形態１に係る空気調和機は、「トーン・エントロピー法」に基づいて運転を制御する。具体的には、「トーン・エントロピー法」に基づいて算出される「トーン値」と「エントロピー値」を用いて運転を制御する。また、後述する実施の形態２ではさらに、一拍毎の「トーン・エントロピー法」に基づいて算出される「トーン値」と「エントロピー値」を用いて算出される２点間の距離である「移動量」を用いて運転を制御する。そのため、ここではまず、「トーン・エントロピー法」について説明する。 (Embodiment 1)

The air conditioner according to
図１は、心拍波形の一例を示す図である。図２は、ＰＩ度数分布の一例を示す図である。「トーン・エントロピー法」は、図１に示すように、心拍波形（心電図波形）におけるＲ－Ｒ間隔の変化率に基づく心臓自律神経活動計測法のことであり、様々な分野で使用されている。このトーン・エントロピー法では、まず、Ｒ－Ｒ間隔の変化率ＰＩ（Ｐｅｒｃｅｎｔａｇｅ Ｉｎｄｅｘ）を算出する。ｎ（整数）番目のＲ－Ｒ間隔ＲＲＩ（ｎ）からｎ＋１番目のＲ－Ｒ間隔ＲＲＩ（ｎ＋１）への変化率ＰＩ（ｎ）は、数式（１）を用いて算出される。
FIG. 1 is a diagram showing an example of a heartbeat waveform. FIG. 2 is a diagram showing an example of PI frequency distribution. The "tone entropy method", as shown in FIG. 1, is a cardiac autonomic nerve activity measurement method based on the rate of change of the RR interval in a heartbeat waveform (electrocardiogram waveform), and is used in various fields. . In this tone entropy method, first, an RR interval change rate PI (Percentage Index) is calculated. A rate of change PI(n) from the n (integer) RR interval RRI(n) to the n+1 RR interval RRI(n+1) is calculated using equation (1).
数式（１）を用いて算出されるＰＩは、心拍数に関連している。ＰＩが正の値である場合、それは心拍数が上昇していることを示している。心拍数の上昇は、交感神経系の活動が、副交感神経系の活動に比べて優位であることを示している。
The PI calculated using Equation (1) is related to heart rate. A positive value of PI indicates an increase in heart rate. An increase in heart rate indicates that sympathetic nervous system activity predominates over parasympathetic nervous system activity.
一方、ＰＩが負の値である場合、それは心拍数が減少していることを示している。心拍数の減少は、副交感神経系の活動が、交感神経系の活動に比べて優位であることを示している。
On the other hand, if the PI is a negative value, it indicates that the heart rate is decreasing. A decrease in heart rate indicates that parasympathetic nervous system activity predominates over sympathetic nervous system activity.
トーン値とエントロピー値とを算出するために、ＰＩは一定の時間の間計測される。すなわち、一定の時間において、Ｎ（整数）個のＰＩ値が取得される。取得されたＮ個のＰＩ値は、Ｍ（整数）個の階級別に分類される。その結果、図２に示すようなＰＩヒストグラム（ＰＩ度数分布）が作製される。例えば、階級ｉは、０～１％の範囲である。図２に示すＰＩ度数分布においては、階級ｉの度数は、ｆｉである。
PI is measured for a certain period of time to calculate the tone value and the entropy value. That is, N (integer) PI values are obtained at a certain time. The obtained N PI values are classified into M (integer) classes. As a result, a PI histogram (PI frequency distribution) as shown in FIG. 2 is created. For example, class i ranges from 0 to 1%. In the PI frequency distribution shown in FIG. 2, the frequency of class i is fi.
トーン値Ｔは、ＰＩ度数分布におけるＰＩの平均値である。トーン値Ｔは、数式（２）を用いて算出される。
The tone value T is the average value of PI in the PI frequency distribution. The tone value T is calculated using Equation (2).
数式（２）を用いて算出されるトーン値Ｔは、心拍数の増減のバランスを示しており、また、交感神経系と副交感神経系がどのようなバランスで活動しているかを示している。
The tone value T calculated using formula (2) indicates the balance between increases and decreases in the heart rate, and also indicates the balance in which the sympathetic nervous system and the parasympathetic nervous system are active.
エントロピー値Ｅは、ＰＩ度数分布における分布の均一性を示す指標である。エントロピー値Ｅは、数式（３）を用いて算出される。
The entropy value E is an index that indicates the uniformity of the PI frequency distribution. The entropy value E is calculated using Equation (3).
ここで、数式（３）内のｐ（ｉ）は、階級ｉの生起確率である。生起確率ｐ（ｉ）は、数式（４）を用いて算出される。
Here, p(i) in formula (3) is the probability of occurrence of class i. The occurrence probability p(i) is calculated using Equation (4).
ここで、数式（４）内のｆｓｕｍは、全階級の度数の合計である。
Here, fsum in formula (4) is the sum of the frequencies of all classes.
数式（３）～（４）を用いて算出されるエントロピー値Ｅが相対的に小さい値である場合、ＰＩ度数分布は、ゼロのＰＩ値に近い階級（図２の場合、階級ｉ、ｉ－１）の度数が他の階級の度数に比べて著しく大きい分布（急峻な山形状の分布）をとる。このことは、自律神経の活動が弱く、心拍数がほとんど変化していないことを示している。一方、エントロピー値Ｅが相対的に大きい値である場合、ＰＩ度数分布は、各階級の度数が概ね均一な分布をとる。すなわち、Ｒ－Ｒ間隔の変化幅が大きく、ＰＩ値の絶対値が大きい。このことは、自律神経の活動が活発で、心拍数が大きく変動していることを示している。したがって、エントロピー値は、自律神経の活動の強弱を示している。
When the entropy value E calculated using the formulas (3) to (4) is a relatively small value, the PI frequency distribution has a class close to the zero PI value (in the case of FIG. 2, classes i, i- The frequency of 1) takes a distribution (steep mountain-shaped distribution) that is significantly larger than the frequency of other classes. This indicates that the activity of the autonomic nerves is weak and the heart rate hardly changes. On the other hand, when the entropy value E is a relatively large value, the PI frequency distribution takes a distribution in which the frequency of each class is generally uniform. That is, the width of change in the RR interval is large, and the absolute value of the PI value is large. This indicates that the autonomic nerves are active and the heart rate fluctuates greatly. Therefore, the entropy value indicates the intensity of autonomic nerve activity.
移動量Ｄは、三平方の定理である数式（５）を用いて算出される。数式（５）では、ＲＲＩ（ｎ）およびＲＲＩ（ｎ＋１）について「トーン・エントロピー法」に基づいて算出される「トーン値Ｔ１」および「エントロピー値Ｅ１」と、ＲＲＩ（ｎ＋１）およびＲＲＩ（ｎ＋２）について「トーン・エントロピー法」に基づいて算出される「トーン値Ｔ２」および「エントロピー値Ｔ２」が用いられる。なお、移動量は、トーン－エントロピーマップ上における、（ｎ－１）拍目のトーン値およびエントロピー値の組み合わせを示すプロットとｎ拍目のトーン値およびエントロピー値の組み合わせを示すプロットとの間の直線距離に該当する。
The movement amount D is calculated using the Pythagorean formula (5). In expression (5), the "tone value T1" and "entropy value E1" calculated based on the "tone entropy method" for RRI(n) and RRI(n+1), RRI(n+1) and RRI(n+2) A "tone value T2" and an "entropy value T2" calculated based on the "tone entropy method" are used. Note that the amount of movement is the difference between the plot showing the combination of the tone value and entropy value at the (n-1)th beat and the plot showing the combination of the tone value and entropy value at the nth beat on the tone-entropy map. Corresponds to straight-line distance.
なお、トーン値とエントロピー値とを算出するために必要な心拍波形におけるＲ－Ｒ間隔ＲＲＩの代わりに、心拍数や脈拍数を利用することも可能である。Ｒ－Ｒ間隔が、心拍数や脈拍数と対応関係にあるからである。例えば、Ｒ－Ｒ間隔が１秒である場合、心臓の心室が一秒間に一回収縮しているため、心拍数（１分あたり）は６０回である。また、不整脈などの疾患がない場合には、心拍数と脈拍数は同一である。したがって、トーン値やエントロピー値を算出するために、心拍数や脈拍数を利用することが可能である。
It is also possible to use the heart rate and pulse rate instead of the RR interval RRI in the heartbeat waveform necessary for calculating the tone value and the entropy value. This is because the RR interval has a corresponding relationship with the heart rate and pulse rate. For example, if the RR interval is 1 second, the heart rate (per minute) is 60 because the ventricles of the heart are contracting once per second. Moreover, when there is no disease such as arrhythmia, the heart rate and the pulse rate are the same. Therefore, heart rate and pulse rate can be used to calculate tone and entropy values.
図３は、本開示におけるトーン－エントロピーマップを示す図である。今回、本開示の発明者は、トーン値Ｔとエントロピー値Ｅが、図３に示すように、空気調和機のユーザの「温冷感」と対応していることを見出した。このため、本開示の空気調和機では、このようなトーン・エントロピー法に基づくトーン値Ｔおよびエントロピー値Ｅを用いて運転制御を行う。ここではまず、発明者によって今回新たに見出された知見について説明する。
FIG. 3 is a diagram showing a tone-entropy map in the present disclosure. This time, the inventor of the present disclosure has found that the tone value T and the entropy value E correspond to the "thermal sensation" of the user of the air conditioner, as shown in FIG. Therefore, in the air conditioner of the present disclosure, operation control is performed using the tone value T and the entropy value E based on such tone entropy method. Here, first, the findings newly discovered by the inventors will be described.
なお、ここでの「温冷感」は、暑さ、温かさ、涼しさ、寒さなどの周囲環境温度についてのユーザの体感を言う。
It should be noted that the "thermal sensation" here refers to the user's bodily sensation of the surrounding environment temperature, such as heat, warmth, coolness, and coldness.
図３は、一方の軸（縦軸）がトーン値Ｔを表し、他方の軸（横軸）がエントロピー値Ｅを表す、トーン－エントロピーマップである。
FIG. 3 is a tone-entropy map in which one axis (vertical axis) represents the tone value T and the other axis (horizontal axis) represents the entropy value E.
発明者は、図３に示すように、暑すぎることもなくまた寒すぎることもない快適な体感（例えば室温１８～２８度の室内にいるときの体感）に対応するトーン値とエントロピー値の組み合わせが存在することを、実験的に突き止めた。すなわち、トーン－エントロピーマップにおいて、ユーザが快適と感じる快適領域Ａｓの存在を突き止めた。
As shown in FIG. 3, the inventor found a combination of the tone value and the entropy value corresponding to a comfortable feeling that is neither too hot nor too cold (for example, the feeling when being in a room with a room temperature of 18 to 28 degrees). It was found experimentally that That is, in the tone-entropy map, the existence of a comfortable region As where the user feels comfortable was found.
また、発明者は、図３に示すように、暑すぎて不快な体感に対応するトーン値とエントロピー値の組み合わせ、すなわちトーン－エントロピーマップにおける不快領域Ａｈ（第１の不快領域）を実験的に突き止めた。
In addition, as shown in FIG. 3, the inventor experimentally determined the combination of the tone value and the entropy value corresponding to the sensation of being too hot and uncomfortable, that is, the discomfort region Ah (first discomfort region) in the tone-entropy map. I pinpointed it.
さらに、発明者は、図３に示すように、寒すぎて不快な体感に対応するトーン値とエントロピー値の組み合わせ、すなわちトーン－エントロピーマップにおける不快領域Ａｃ（第２の不快領域）を実験的に突き止めた。
Furthermore, as shown in FIG. 3, the inventor experimentally determined the combination of the tone value and the entropy value corresponding to the feeling of being too cold and uncomfortable, that is, the discomfort area Ac (second discomfort area) in the tone-entropy map. I pinpointed it.
このようなトーン値Ｔとエントロピー値Ｅの組み合わせとユーザの温冷感との対応関係は、温度が異なる複数の温度環境下に複数のユーザ（被験者）をおき、その複数のユーザのトーン値とエントロピー値Ｅを計測することによって突き止められる。
The correspondence relationship between the combination of the tone value T and the entropy value E and the user's thermal sensation is obtained by placing a plurality of users (subjects) under a plurality of temperature environments with different temperatures, and comparing the tone values of the plurality of users. It is ascertained by measuring the entropy value E.
例えば、図４は、一被験者の複数の温度環境下におけるトーン値とエントロピー値の変化を示している。また、図５は、複数の温度環境下における収束状態のトーン値とエントロピー値とを示している。
For example, Fig. 4 shows changes in tone value and entropy value under multiple temperature environments for one subject. FIG. 5 also shows converged tone values and entropy values under a plurality of temperature environments.
図４および図５に示すように、３５度の温度環境下、すなわち被験者が暑すぎて不快に感じる環境下でのトーン値Ｔとエントロピー値Ｅと、２度の温度環境下、すなわち被験者が寒すぎて不快に感じる環境下でのトーン値Ｔとエントロピー値Ｅとは、トーン－エントロピーマップにおいて分布範囲が異なる。
As shown in FIGS. 4 and 5, the tone value T and the entropy value E under a temperature environment of 35 degrees, that is, an environment where the subject is too hot to feel uncomfortable, and a temperature environment of 2 degrees, that is, when the subject is cold. The tone value T and the entropy value E in an environment that is too uncomfortable have different distribution ranges in the tone-entropy map.
具体的には、図４に示すように、暑すぎて不快である場合（３５度の場合）のトーン値Ｔは、０～－０．０５％の範囲に集中し、一方、寒すぎて不快である場合（２度の場合）のトーン値Ｔは、－０．２５～－０．４％の範囲に集中している。
Specifically, as shown in FIG. 4, the tone value T when it is too hot and uncomfortable (35 degrees) is concentrated in the range of 0 to -0.05%, while when it is too cold and uncomfortable (2 degrees), the tone value T is concentrated in the range of -0.25 to -0.4%.
また暑すぎて不快である場合（３５度の場合）のエントロピー値Ｅは、３～３．５の範囲に集中し、一方、寒すぎて不快である場合（２度の場合）のエントロピー値Ｅは、４．５～５の範囲に集中している。
The entropy value E when it is too hot and uncomfortable (35 degrees) is concentrated in the range of 3 to 3.5, while the entropy value E when it is too cold and uncomfortable (2 degrees) are concentrated in the range of 4.5-5.
したがって、図３に示すトーン－エントロピーマップにも示すように、また、トーン値Ｔとエントロピー値Ｅが収束した状態（安定した状態）を示す図５からも明らかなように、暑すぎて不快である場合のトーン値とエントロピー値の組み合わせを含む不快領域Ａｈは、寒すぎて不快である場合のトーン値とエントロピー値の組み合わせを含む不快領域Ａｃに対して、トーン値が高く且つエントロピー値が低い（弱い）。したがって、トーン値Ｔとエントロピー値Ｅとに基づいて、ユーザが、暑すぎて不快であるのか、あるいは寒すぎて不快であるのかを区別することが可能である。
Therefore, as shown in the tone-entropy map shown in FIG. 3, and also as is clear from FIG. The discomfort region Ah containing the combination of tone value and entropy value in a certain case has a high tone value and a low entropy value with respect to the discomfort region Ac containing the combination of tone value and entropy value when it is too cold to be uncomfortable. (weak). Therefore, based on the tone value T and the entropy value E, it is possible to distinguish whether the user is too hot to be uncomfortable or too cold to be uncomfortable.
また、図４および図５に示すように、ユーザが快適と感じる場合（２０度および２３度の場合）、そのトーン値とエントロピー値との組み合わせは、暑すぎる場合の不快領域Ａｈと、寒すぎる場合の不快領域Ａｃとの間に概ね分布する。したがって、図３に示すように、トーン－エントロピーマップにおいて、ユーザが快適な快適領域Ａｓは、不快領域Ａｈと不快領域Ａｃとの間に位置する。
Also, as shown in FIGS. 4 and 5, when the user feels comfortable (20 degrees and 23 degrees), the combination of the tone value and the entropy value is the discomfort area Ah when it is too hot, and the discomfort area Ah when it is too cold. It is generally distributed between the discomfort area Ac of the case. Therefore, as shown in FIG. 3, in the tone-entropy map, the user's comfort area As is located between the discomfort area Ah and the discomfort area Ac.
以上のようなトーン－エントロピーマップ、すなわちトーン値およびエントロピー値の組み合わせとユーザの温冷感との間の対応関係にについて得られた新たな知見に基づいて、本開示の空気調和機においては、ユーザの体感が快適になるように空気調和機の運転を制御する。
Based on new knowledge obtained about the correspondence relationship between the tone-entropy map as described above, that is, the combination of the tone value and the entropy value and the user's thermal sensation, the air conditioner of the present disclosure: To control the operation of an air conditioner so that a user feels comfortable.
すなわち、本開示の空気調和機では、ユーザのトーン値Ｔとエントロピー値Ｅが快適領域Ａｓ内に存在するように空気調和機の運転を制御する。また、トーン値Ｔとエントロピー値Ｅが不快領域ＡｈまたはＡｃに存在するときは、ユーザが明らかに暑すぎて不快または寒すぎて不快と感じているので、その不快が解消される運転を実行する。以下、本開示の空気調和機について、具体的に説明する。
That is, the air conditioner of the present disclosure controls the operation of the air conditioner so that the user's tone value T and entropy value E are within the comfort area As. Also, when the tone value T and the entropy value E are in the discomfort region Ah or Ac, the user clearly feels uncomfortable because it is too hot or too cold and feels uncomfortable. . The air conditioner of the present disclosure will be specifically described below.

図１１は、一被験者の複数の温度環境下におけるトーン／エントロピー値の変化について、時系列的に連続した収束状態のトーン／エントロピー値同士を直線で結んだ移動量として示した模式図である。また、図１２は、温度環境によって異なる移動量の違いを示す模式図である。
FIG. 11 is a schematic diagram showing changes in tone/entropy values in a plurality of temperature environments of one subject as moving amounts connecting consecutive tone/entropy values in a converged state in time series with straight lines. Moreover, FIG. 12 is a schematic diagram showing the difference in movement amount depending on the temperature environment.
発明者は、図１２の模式図に示すように、暑すぎることもなくまた寒すぎることもない快適な体感、例えば室温１８～２８度の室内にいるときの体感に対応するトーン／エントロピー値の移動量の範囲が存在することを、今回実験的に突き止めた。すなわち、ユーザが快適と感じる快適な移動量の範囲Ｄｓの存在を突き止めた。
As shown in the schematic diagram of FIG. 12, the inventors found a tone/entropy value corresponding to a comfortable feeling that is neither too hot nor too cold, for example, a feeling in a room with a room temperature of 18 to 28 degrees. It was found experimentally this time that there is a range of the amount of movement. In other words, the existence of a comfortable moving amount range Ds that the user feels comfortable has been found.
また、発明者は、図１２に示すように、暑すぎて不快な体感に対応するトーン／エントロピー値の移動量、すなわちトーン－エントロピーマップにおける暑すぎて不快な移動量の範囲Ｄｈを実験的に突き止めた。
In addition, as shown in FIG. 12, the inventor experimentally determined the amount of movement of the tone/entropy value corresponding to the feeling of being too hot and uncomfortable, that is, the range Dh of the amount of movement being too hot and uncomfortable in the tone-entropy map. I pinpointed it.
さらに、発明者は、図１２に示すように、寒すぎて不快な体感に対応するトーン／エントロピー値の移動量、すなわちトーン－エントロピーマップにおける寒すぎて不快な移動量の範囲Ｄｃを実験的に突き止めた。
Furthermore, as shown in FIG. 12, the inventor experimentally determined the amount of movement of the tone/entropy value corresponding to the feeling of being too cold and uncomfortable, that is, the range Dc of the amount of movement being too cold and uncomfortable in the tone-entropy map. I pinpointed it.
このようなトーン／エントロピー値の移動量と、ユーザの温冷感との対応関係は、温度が異なる複数の温度環境下に複数のユーザ（被験者）をおき、その複数のユーザのトーン／エントロピー値の移動量を計測することによって突き止められた。
The correspondence relationship between the amount of change in tone/entropy value and the user's thermal sensation can be obtained by placing a plurality of users (subjects) under a plurality of temperature environments with different temperatures and calculating the tone/entropy values of the plurality of users. It was ascertained by measuring the amount of movement of
図１３は、一被験者の複数の温度環境下におけるトーン／エントロピー値の変化について、収束状態のトーン値およびエントロピー値を直線で結んだ移動量の実測値を示している。また、図１４は、一被験者の複数の温度環境下におけるトーン／エントロピー値の変化について、収束状態のトーン値およびエントロピー値を直線で結んで得られる移動量から、暑すぎて不快領域、快適領域、および寒すぎて不快領域を突き止めた際のグラフを示している。
Fig. 13 shows the actual measurement values of the amount of movement connecting the converged tone value and entropy value with a straight line with respect to changes in tone/entropy value under multiple temperature environments of one subject. In addition, FIG. 14 shows changes in tone/entropy values under multiple temperature environments for one subject. , and a graph when locating the too cold discomfort area.
図１４に示すように、３５度の温度環境下、すなわち被験者が暑すぎて不快に感じる環境下でのトーン／エントロピー値の移動量は、２度の温度環境下、すなわち被験者が寒すぎて不快に感じる環境下でのトーン／エントロピー値の移動量と異なる。
As shown in FIG. 14, the amount of tone/entropy value shift under a temperature environment of 35 degrees, i.e., an environment where the subject feels too hot and uncomfortable, is less than that in a temperature environment of 2 degrees, i. It is different from the amount of movement of the tone/entropy value under the environment that is felt in the environment.
具体的には、図１４に示すように、暑すぎて不快である場合（３５度の場合）のトーン／エントロピー値の移動量は、１９以下である。一方、寒すぎて不快である場合（２度の場合）のトーン／エントロピー値の移動量は、２７以上である。
Specifically, as shown in FIG. 14, the amount of change in tone/entropy value when it is too hot and uncomfortable (35 degrees) is 19 or less. On the other hand, when it is too cold to be comfortable (at 2 degrees), the shift in tone/entropy value is 27 or more.
したがって、図１４からも明らかなように、暑すぎて不快である場合の移動量は、寒すぎて不快である移動量よりも小さい。したがって、トーン／エントロピー値の移動量に基づいて、ユーザが、暑すぎて不快であるのか、あるいは寒すぎて不快であるのかを区別することが可能である。
Therefore, as is clear from FIG. 14, the amount of movement when it is too hot and uncomfortable is smaller than the amount of movement when it is too cold and uncomfortable. Therefore, based on the amount of shift in tone/entropy value, it is possible to distinguish whether the user is too hot to be uncomfortable or too cold to be uncomfortable.
また、図１４に示すように、ユーザが快適と感じる場合（２０度および２３度の場合）、トーン／エントロピー値の移動量は、暑すぎて不快な場合の移動量の範囲Ｄｈと、寒すぎて不快な場合の移動量の範囲Ｄｃとの中間の範囲に収束する。
Also, as shown in FIG. 14, when the user feels comfortable (at 20 degrees and 23 degrees), the amount of movement of the tone/entropy value is the range of movement Dh when it is too hot and uncomfortable, and when it is too cold. It converges to a range intermediate to the range Dc of the amount of movement when it is uncomfortable.
以上のようなトーン－エントロピーマップ、すなわちトーン／エントロピー値の移動量とユーザの温冷感との間の対応関係について得られた新たな知見に基づいて、本開示の空気調和機においては、ユーザの体感が快適になるように空気調和機の運転を制御する。
Based on the new knowledge obtained about the correspondence relationship between the tone-entropy map as described above, that is, the amount of movement of the tone/entropy value and the user's thermal sensation, the air conditioner of the present disclosure provides the user control the operation of the air conditioner so that the feeling of air conditioning is comfortable.
