(Embodiment 1)
An air conditioner according to one aspect of the present invention includes a vital signs measuring device that measures the pulse or heartbeat of a user in a room, and a tone value and an entropy value obtained from the detection results of the vital signs measuring device using a tone entropy method. a movement amount calculation unit that calculates a linear movement amount between two points of the tone/entropy value for each beat; a combination of the tone value and the entropy value; and the thermal sensation of the user Based on the correspondence between and an operation control unit that controls the operation of the air conditioner, and the movement amount calculated by the movement amount calculation unit based on the correspondence relationship between the movement amount and the thermal sensation of the user is determined to be a comfortable temperature for the user. and the operation control unit incorporating an operation program that provides a movement amount corresponding to the cooling sensation.

According to such an aspect, in the air conditioner, it is possible to consider the thermal sensation of the user and perform a comfortable operation for the user.

For example, the air conditioner may have a tone-entropy map showing the correspondence, one axis representing tone values and the other axis representing entropy values. In this case, the operation control unit controls the tone value and the entropy value calculated by the tone/entropy calculation unit so that they are within the comfort region in the tone-entropy map corresponding to the comfortable thermal sensation of the user. Second, the operation of the air conditioner is controlled.

For example, when the air conditioner is configured to be able to adjust the room temperature in the room, the operation control unit is configured to respond to the user's too hot and uncomfortable thermal sensation in the tone-entropy map. If the tone value and the entropy value calculated by the tone/entropy calculation unit exist in the discomfort region, the operation for lowering the room temperature is executed. Further, when the tone value and the entropy value calculated by the tone/entropy calculation unit exist in the second discomfort region corresponding to the user's too cold and uncomfortable thermal sensation in the tone-entropy map, the Execute an operation that raises the room temperature. As a result, the air conditioner can perform comfortable operation for a user who feels uncomfortable because it is too hot or too cold.

For example, when the air conditioner is configured to be able to perform cooling operation and heating operation and to be able to adjust the amount of air blown to the user, during the cooling operation, the operation control unit controls the tone-entropy map If the tone value and the entropy value calculated by the tone/entropy calculation unit exist in the first discomfort region corresponding to the user's too hot and uncomfortable thermal sensation in If the tone value and the entropy value calculated by the tone/entropy calculation unit are present in a second discomfort region corresponding to the user's too cold and uncomfortable thermal sensation in the tone-entropy map, An operation is performed to decrease the amount of air blown. On the other hand, during the heating operation, the operation control unit places the tone value calculated by the tone/entropy calculation unit in the first discomfort region corresponding to the user's too hot and uncomfortable thermal sensation in the tone-entropy map. If there is an entropy value, perform the operation to decrease the airflow, and perform the tone/entropy calculation in a second discomfort region corresponding to the user's too cold discomfort thermal sensation in the tone-entropy map. If the tone value and the entropy value calculated by the unit exist, the operation for increasing the air flow rate is executed. As a result, the air conditioner can perform comfortable operation for a user who feels uncomfortable because it is too hot or too cold during the cooling operation or the heating operation.

For example, when the air conditioner is configured to be able to adjust the indoor humidity in the room, the operation control unit is configured to respond to the user's too hot and uncomfortable thermal sensation in the tone-entropy map. If the tone value and the entropy value calculated by the tone/entropy calculation unit exist in the discomfort region, the operation for lowering the indoor humidity is executed. Further, when the tone value and the entropy value calculated by the tone/entropy calculation unit exist in the second discomfort region corresponding to the user's too cold and uncomfortable thermal sensation in the tone-entropy map, the Execute the operation to raise the indoor humidity. As a result, the air conditioner can perform comfortable operation for a user who feels uncomfortable because it is too hot or too cold.

For example, the air conditioner may have a tone-entropy map showing the correspondence, one axis representing tone values and the other axis representing entropy values. In this case, the operation control unit uses the movement amount calculation unit based on the tone value and the entropy value calculated by the tone/entropy calculation unit, and the tone-entropy corresponding to the comfortable thermal sensation of the user. The operation of the air conditioner is controlled so as to fall within the comfortable movement amount range Ds on the map.

For example, when the air conditioner is configured to be able to adjust the room temperature in the room, the operation control unit controls an uncomfortable movement corresponding to the user's too hot and uncomfortable thermal sensation in the tone-entropy map. When the movement amount calculated by the movement amount calculation unit falls within the amount range Dh, the operation for lowering the room temperature is executed. Further, when the movement amount calculated by the movement amount calculation unit falls within the uncomfortable movement amount range Dc corresponding to the user's uncomfortable thermal sensation due to being too cold in the tone-entropy map, the indoor temperature is adjusted. Carry out the operation to raise. As a result, the air conditioner can perform comfortable operation for a user who feels uncomfortable because it is too hot or too cold.

For example, when the air conditioner is configured to be able to perform cooling operation and heating operation and to be able to adjust the amount of air blown to the user, during the cooling operation, the operation control unit controls the tone-entropy map when the movement amount calculated by the movement amount calculation unit falls within the unpleasant movement amount range Dh corresponding to the user's too hot and uncomfortable thermal sensation in the above, executing an operation to increase the air blow amount, When the movement amount calculated by the movement amount calculation unit falls within the unpleasant movement amount range Dc corresponding to the user's uncomfortable thermal sensation due to being too cold in the tone-entropy map, the airflow amount is decreased. carry out driving. On the other hand, during the heating operation, the operation control unit determines whether the movement amount calculated by the movement amount calculation unit falls within the uncomfortable movement amount range Dh corresponding to the user's too hot and uncomfortable thermal sensation in the tone-entropy map. If so, the operation for reducing the airflow is executed, and the movement amount calculation unit calculates the discomfort movement amount range Dc corresponding to the user's thermal sensation that is too cold and uncomfortable in the tone-entropy map. If the movement amount is within the above range, the operation for increasing the air blow rate is executed. As a result, the air conditioner can perform comfortable operation for a user who feels uncomfortable because it is too hot or too cold during the cooling operation or the heating operation.

For example, when the air conditioner is configured to be able to adjust the indoor humidity in the room, the operation control unit controls the user's excessively hot and uncomfortable thermal sensation in the tone-entropy map. When the movement amount calculated by the movement amount calculation unit falls within the movement amount range Dh, the operation for reducing the indoor humidity is executed. Further, when the movement amount calculated by the movement amount calculation unit falls within the uncomfortable movement amount range Dc corresponding to the user's feeling of being too cold and uncomfortable in the tone-entropy map, the room humidity is adjusted. Carry out the operation to raise. As a result, the air conditioner can perform comfortable operation for a user who feels uncomfortable because it is too hot or too cold.

The air conditioner, as the vital sign measuring device, emits millimeter waves toward the user, receives the millimeter waves reflected by the user, and measures the heartbeat of the user based on the received millimeter waves. It may have a measuring device.

The air conditioner may have, as the vital signs measuring device, a pulse measuring device that continuously photographs the user with a camera and measures the pulse based on the change in hue of the image of the user captured in the continuously photographed images. good.

The air conditioner may have, as the vital signs measuring device, an electrocardiograph worn by the user to measure the user's heartbeat.

As the vital sign measuring device, the air conditioner is worn by the user, emits infrared rays toward the user, receives the infrared rays reflected by the user, and measures the user's pulse based on the received infrared rays. You may have a pulse measuring device that

An embodiment of the present invention will be described below.

The air conditioner according to the present invention is based on the "tone entropy method". Specifically, in the air conditioner according to the present invention, the "tone value" and "entropy value" calculated based on the "tone entropy method" and the "tone entropy method" for each beat are calculated based on The operation is controlled using the "tone value" and "entropy value" that are calculated, and the "movement amount" that calculates the distance between two points by the Pythagorean theorem. Therefore, first, the "tone entropy method" will be explained.

The tone entropy method, as shown in FIG. 1, is a cardiac autonomic nerve activity measurement method based on the rate of change of RR intervals in a heartbeat waveform (electrocardiogram waveform), and is used in various fields. In this tone entropy method, first, the 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).

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.

On the other hand, if PI is negative, 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.

To calculate the tone and entropy values, PI is measured over a period of time (N (integer) PI values are taken). The 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 Equation (2) indicates the balance between increases and decreases in 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 indicating the uniformity of the PI frequency distribution. The entropy value E is calculated using Equation (3).

Here, p(i) in Equation (3) is the probability of occurrence of class i. The occurrence probability p(i) is calculated using Equation (4).

Here, fsum in Equation (4) is the sum of frequencies for all classes.

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-1 ) has a significantly higher frequency than other classes (steep mountain-shaped distribution). 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.

The amount of movement D is RRI(n) to RRI(n+1), "tone value T1" and "entropy value E1" calculated based on the "tone entropy method", and RRI(n+1) to RRI(n+2). are calculated based on the "tone entropy method" and the "tone value T2" and the "entropy value T2" are calculated using the Pythagorean theorem (5).

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.

The reason why the tone value T and the entropy value E based on the tone entropy method are used for the operation control of the air conditioner is that the inventor of the present invention believes that the tone value T and the entropy value E are as shown in FIG. , corresponds to the "thermal sensation" of the user of the air conditioner.

It should be noted that the term "thermal sensation" as used herein refers to a user's perception of the temperature of the surrounding environment, such as heat, warmth, coolness, or 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. FIG.

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.

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.

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.

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 was ascertained by measuring the entropy value E.

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.

As shown in FIGS. 4 and 5, the tone value T and the entropy value E under a temperature environment of 35 degrees, i.e., an environment where the subject is too hot to feel uncomfortable, are different from those in a temperature environment of 2 degrees, i.e., when the subject is cold. The distribution ranges are different in the tone-entropy map for the tone value T and the entropy value E in an environment that is too uncomfortable.

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%.

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.

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.

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 comfort area As, where the user is comfortable, is located between the discomfort areas Ah, Ac.

Based on the tone-entropy map as described above, that is, the correspondence relationship between the combination of the tone value and the entropy value and the thermal sensation of the user, the inventors determined the air conditioner to make the user feel comfortable. Thought to control driving.

That is, the inventor considered controlling the operation of the air conditioner so that the user's tone value T and entropy value E are within the comfort zone 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. I thought. From now on, the air conditioner for that purpose will be specifically described.

FIG. 6 schematically shows a room (room) in which an air conditioner according to one embodiment of the present invention is installed. Moreover, FIG. 7 is a schematic block diagram of an air conditioner. Furthermore, FIG. 8 is a block diagram of the control system of the air conditioner.

As shown in FIG. 7 , the air conditioner 10 according to this embodiment has an indoor unit 12 and an outdoor unit 14 .

As shown in FIG. 6, the indoor unit 12 of the air conditioner 10 is installed in the room R (indoor). The outdoor unit 14 is installed outside the room R (outdoor). A user U of the air conditioner 10 is in a room R in which the indoor unit 12 is installed.

As shown in FIG. 7, the air conditioner 10 includes an indoor heat exchanger 16 provided in the indoor unit 12, an outdoor heat exchanger 18 provided in the outdoor unit 14, a compressor 20 for compressing the refrigerant, It has a four-way valve 22 that switches the flow direction of the refrigerant, an expansion valve 24 that reduces the pressure of the refrigerant, and a refrigerant pipe 26 that connects them. In addition, the indoor unit 12 is provided with an indoor fan 28 that blows the air after heat exchange with the indoor heat exchanger 16 into the room, and an up-down louver 30 that changes the direction of the wind W sent out from the indoor unit 12. It is Furthermore, the outdoor unit 14 is provided with an outdoor fan 32 that blows the air after heat exchange with the outdoor heat exchanger 18 to the outdoors.

FIG. 7 shows the state of the air conditioner 10 during cooling operation. During cooling operation, the refrigerant discharged from the compressor 20 returns to the compressor 20 through the four-way valve 22, the outdoor heat exchanger 18, the expansion valve 24, the indoor heat exchanger 16, and the four-way valve 22 in order. On the other hand, during heating operation, the refrigerant discharged from the compressor 20 passes through the four-way valve 22, the indoor heat exchanger 16, the expansion valve 24, the outdoor heat exchanger 18, and the four-way valve 22 in order and returns to the compressor 20. .

The indoor fan 28 blows air cooled by heat exchange with the indoor heat exchanger 16 into the room R during cooling operation, and blows air warmed by heat exchange with the indoor heat exchanger 16 during heating operation. to blow air.

The upper and lower louvers 30 change the direction of air (air after heat exchange with the indoor heat exchanger 16) (wind W) blown from the indoor unit 12 into the room R. The upper and lower louvers 30 change the blowing direction, for example, between the direction in which the air is directed toward the ceiling of the room R and the direction in which the air is directed toward the floor.

The outdoor fan 32 discharges the air after heat exchange with the outdoor heat exchanger 18 to the outside.

As shown in FIG. 8 , the air conditioner 10 has a controller 50 that controls the compressor 20 , the four-way valve 22 , the indoor fan 28 , the vertical louvers 30 and the outdoor fan 32 .

The control device 50 has an operation control section 52 that controls the operation of the air conditioner 10 , that is, controls the compressor 20 , the four-way valve 22 , the indoor fan 28 , the vertical louver 30 and the outdoor fan 32 . The control device 50 also includes a heartbeat data acquisition unit 54 that acquires heartbeat data of the user, a tone/entropy value calculation unit 56 that calculates the tone value T and the entropy value E of the user, and a storage unit 58 .

The control device 50 (its operation control unit 52, heartbeat data acquisition unit 54, and tone/entropy calculation unit 56) is provided, for example, in the outdoor unit 14, and includes a CPU (arithmetic processing unit) such as a microcomputer, ROM, RAM, and the like. It is a control board provided with a memory (storage unit 58), a circuit connecting these, a port for communicating with the outside, and the like. The controller 50 is also connected to the compressor 20, the four-way valve 22, the indoor fan 28, the upper and lower louvers 30, and the outdoor fan 32 via signal lines for controlling them. Further, the control device 50 performs various operations by causing the arithmetic processing device to execute programs stored in the storage device.

As shown in FIG. 8, the controller 50 is communicatively connected to the remote controller 34 and the vital signs measuring device 36 .

The remote controller 34 is a device for the user U to operate the air conditioner 10, that is, a device for the user U to set the operating conditions of the air conditioner 10, as shown in FIG. For example, when the user sets the indoor temperature in the room R via the remote controller 34 (inputs the set temperature), the operation control unit of the controller 50 controls the room temperature to maintain the set temperature. 52 regulates the output of compressor 20;

Also, when the user U changes the operation from the cooling operation to the heating operation or vice versa via the remote controller 34, the operation control unit 52 controls the four-way valve 22 to switch the flow direction of the refrigerant.

Furthermore, when the user U sets the air volume from the indoor unit 12 via the remote controller 34 (inputs the set air volume), the operation control unit 52 adjusts the rotation speed of the indoor fan 28 so as to maintain the set air volume. Adjust.

Furthermore, when the user U sets the blowing direction of the indoor unit 12 via the remote controller 34, the operation control unit 52 adjusts the tilt of the vertical louver 30 with respect to the horizontal axis so that the set blowing direction is achieved. That is, the amount of air blown to the user U is adjusted by changing the wind direction.

In addition, when the user U sets a predetermined indoor humidity via the remote controller 34 (inputs the set humidity), the operation control unit 52 operates the compressor 20 and the four-way valve 22 to achieve the set humidity. Dehumidification operation is controlled.

In the present embodiment, the vital signs measuring device 36 is a non-contact device that measures the user's heart rate without contacting the user, and is mounted on the indoor unit 12 as shown in FIG. .

In this embodiment, the vital sign measuring device 36 emits millimeter waves toward the user U, receives millimeter waves reflected by the user U, and measures the heartbeat of the user based on the received millimeter waves. A non-contact heart rate measurement device configured to measure The vital sign measuring device 36 periodically measures the heart rate of the user U. The heartbeat data measured by the vital signs measuring device 36 is also transmitted to the heartbeat data acquisition unit 54 of the control device 50 .

The vital sign measuring device 36 is a pulse device that continuously photographs the user U with a camera and measures the pulse based on the change in hue of the image of the user (especially the image of the face) captured in the continuously photographed images. may This is because, as described above, heartbeat and pulse correspond to each other.

When the heartbeat data acquisition unit 54 of the control device 50 acquires the heartbeat data from the vital signs measuring device 36, the tone/entropy calculation unit 56 calculates the tone value T and the entropy value E from the acquired heartbeat data (described above). (based on equations (1)-(4)).

The operation control unit 52 calculates the user's Check the thermal sensation of U.

When the tone value T and the entropy value E calculated by the tone/entropy calculation unit 56 are present in the comfort region As in the tone-entropy map shown in FIG. To maintain, maintain the currently running operation (ie, maintain room temperature, airflow, airflow direction, and room humidity). This makes it possible to maintain a comfortable feeling for the user.

Further, when the tone value T and the entropy value E calculated by the tone/entropy calculation unit 56 are outside the comfort region As, the operation control unit 52 calculates the tone value calculated by the tone/entropy calculation unit 56 from this. Driving is controlled so that T and the entropy value E are within the comfort zone As. Specifically, at least one of the compressor 20, the four-way valve 22, the indoor fan 28, and the upper and lower louvers 30 is controlled to adjust at least one of the indoor temperature, air flow rate, air blow direction, and indoor humidity. Whether or not the adjustment is appropriate can be judged by whether or not the tone value T and the entropy value E calculated after the adjustment approach the comfort area As. This makes it possible for the user to feel comfortable.

Furthermore, as shown in FIG. 9, when the tone value T and the entropy value E calculated by the tone/entropy calculation unit 56 are present in the discomfort region Ah corresponding to the user U's feeling of being too hot and uncomfortable (point C1). During the cooling operation, the operation control unit 52 executes at least one of an operation for lowering the indoor temperature, an operation for increasing the amount of air blown to the user U, and an operation for lowering the indoor humidity. In order to lower the indoor temperature, the output of the compressor 20 is increased. Also, in order to increase the amount of air blown to the user U, the number of rotations of the indoor fan 28 is increased and/or the vertical louver 30 is used to change the air blow direction toward the floor. Furthermore, the dehumidifying operation is performed to lower the indoor humidity. For example, when the output of the compressor 20 is maximum, the rotation speed of the indoor fan 28 is increased. A situation in which the user U is too hot during the cooling operation and feels uncomfortable is, for example, a situation in which the user U, who has been out on a hot summer day, returns to the room R that has been sufficiently cooled by the cooling operation. .

On the other hand, during the heating operation, the operation control unit 52 executes at least one of an operation for lowering the indoor temperature, an operation for reducing the amount of air blown to the user U, and an operation for lowering the indoor humidity. A situation in which the user U feels uncomfortable due to excessive heat during the heating operation includes, for example, immediately after the user U has had a warm meal or just after taking a bath.

By these operation controls, as shown in FIG. 9, the tone value T and the entropy value E (point C1) can be shifted from the discomfort region Ah to the comfort region As. As a result, the feeling of the user U who is too hot and uncomfortable can be shifted to a comfortable feeling.

Furthermore, as shown in FIG. 10, when the tone value T and the entropy value E calculated by the tone/entropy calculation unit 56 are present in the discomfort region Ac corresponding to the user U's feeling of being too cold and uncomfortable (point C2 ), the operation control unit 52 performs at least one of an operation for increasing the indoor temperature, an operation for decreasing the amount of air blown to the user U, and an operation for increasing the indoor humidity during the cooling operation. In order to increase the indoor temperature, the output of the compressor 20 is decreased. In order to reduce the amount of air blown to the user U, the rotation speed of the indoor fan 28 is lowered and/or the air blow direction is changed to the ceiling direction by the vertical louvers 30 . It should be noted that situations in which the user U feels uncomfortable due to being too cold during cooling operation include, for example, a situation immediately after eating a cold meal or taking off clothes.

On the other hand, during the heating operation, the operation control unit 52 executes at least one of an operation for increasing the indoor temperature, an operation for increasing the amount of air blown to the user U, and an operation for increasing the indoor humidity. As a situation in which the user U is too cold during the heating operation and feels uncomfortable, for example, the user U who has been out on a cold winter day returns to the room R that has been sufficiently warmed by the heating operation. situation.

By these operation controls, as shown in FIG. 10, the tone value T and the entropy value E (point C2) can be shifted from the discomfort region Ac to the comfort region As. As a result, the feeling of the user U who is too cold and uncomfortable can be shifted to a comfortable feeling.

As described above, according to the present embodiment as described above, in the air conditioner, it is possible to execute a comfortable operation for the user in consideration of the user's thermal sensation.
In addition, FIG. 11 shows a schematic diagram of the amount of movement that connects straight lines between continuous tone/entropy values in a converged state in time series from the amount of change in tone/entropy value in a plurality of temperature environments of one subject. ing.

As shown in the schematic diagram of FIG. 12, the inventors found a tone/entropy value corresponding to a comfortable experience that is neither too hot nor too cold (for example, the experience when being in a room with a room temperature of 18 to 28 degrees). It was found experimentally that there is a movement amount range of . In other words, the existence of a comfortable movement amount range Ds in which the user feels comfortable was ascertained.

In addition, the inventors experimentally determined the shift amount of the tone/entropy value corresponding to the feeling of being too hot and uncomfortable, that is, the discomfort shift amount range Dh in the tone-entropy map, as shown in FIG.

Furthermore, the inventors have experimentally determined the amount of shift in the tone/entropy value corresponding to the feeling of being too cold and uncomfortable, ie, the discomfort shift range Dc in the tone-entropy map, as shown in FIG.

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 determining the tone/entropy values of the plurality of users. It was ascertained by measuring the amount of movement.

Also, FIG. 13 shows the measured value of the amount of movement obtained by measuring the converged tone value and the entropy value on a straight line from the changes in the tone/entropy value under a plurality of temperature environments of one subject.

In addition, FIG. 14 shows changes in tone/entropy values under multiple temperature environments for one subject. It shows the actual measurement value when the area / too cold and uncomfortable area is identified.

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. The shift amount of the tone/entropy value differs from the shift amount of the tone/entropy value under the environment that is perceived as

Specifically, as shown in FIG. 14, the amount of shift in tone/entropy value when it is too hot and uncomfortable (35 degrees) shows a numerical value of 19 or less, while it is too cold and uncomfortable. The shift amount of the tone/entropy value in case (case of 2 degrees) indicates a numerical value of 27 or more.

Therefore, as is clear from FIG. 14, the uncomfortable movement amount Dh when it is too hot and uncomfortable is smaller than the uncomfortable movement amount Dc when it is too cold and uncomfortable. Therefore, based on the amount of movement, it is possible to distinguish whether the user is too hot to be uncomfortable or too cold to be uncomfortable.

Further, as shown in FIG. 14, when the user feels comfortable (at 20 degrees and 23 degrees), the amount of movement is an uncomfortable movement amount range Dh when it is too hot and an uncomfortable movement amount range Dc when it is too cold. The amount of movement converges in the intermediate range between .

Based on the tone-entropy map as described above, that is, the correspondence relationship between the amount of movement and the thermal sensation of the user, the inventors have found that the operation of the air conditioner can be controlled so that the user feels comfortable. thought.

That is, the inventor considered controlling the operation of the air conditioner so that the amount of movement of the user is within the comfortable movement amount Ds. Further, when the amount of movement is within the uncomfortable movement amount Dh or Dc, the user clearly feels uncomfortable because it is too hot or uncomfortable because it is too cold. . From now on, the air conditioner for that purpose will be specifically described.
