The above configuration is common to the following embodiments. In addition to the basic configuration as described above, this embodiment may have the following configuration.

(1) In the air conditioning system 2 of this embodiment, as shown in FIG.
When the room temperature falls below the preset lower limit temperature 41 that triggers poor physical condition during the seasonal transition period from winter to spring or from autumn to winter,
The air conditioning control device 6 automatically starts the heating operation by the air conditioning device 4 to raise the room temperature to the user's heating set temperature 42 regardless of whether the power supply (power switch 28) is on or off.

Here, in the case of Japan, there are basically four seasons: spring, summer, autumn and winter. The seasonal transition period is the intermediate period between the four seasons of spring, summer, autumn and winter. The transition period of the seasons is a delicate time when the climate is not clear and the temperature difference is likely to increase, making it difficult to manage one's physical condition.

Looking at the functional changes in the body that accompany seasonal changes, one year can be divided into the following eight periods (seasons) from A to H, including the seasonal transition periods.
A. Mid-winter (early January to mid-February) Low temperature period Dry periodB. Transition period between winter and spring (Late February to end of March) Warming period C. Spring (from early April to the beginning of the rainy season) Temperature rising period High humidity periodD. Rainy season (beginning of rainy season to end of rainy season) High temperature period High humidity periodE. Midsummer (from the end of the rainy season to the end of August) High temperature period High humidity periodF. Early autumn (late August to late September) Cooling period G. Late autumn (early October to end of November) Cooling period H. Early winter (early December to end of December) Cooling season Dry season

Of these, the seasonal transition period from winter to spring is mainly "B. Winter-spring transition period (late February to end of March)" in early spring. Also, the seasonal transition period from autumn to winter is mainly "G. late autumn (early October to end of November)" at the beginning of autumn.

Normally, heating is performed mainly around "A. midwinter" and "H. early winter". Also, in the normal case, cooling is mainly performed around "E. Midsummer". As for the other seasons, although there is a need for cooling and heating when looking at the heat balance of the body, in reality, cooling and heating are not performed much.

Therefore, in this embodiment, mainly, "B. Winter-spring transition period (late February to end of March)" in early spring and "G. Late autumn (early October to end of November)" in early autumn. By automatically performing heating operation in the period when heating is not performed, the heat balance of the insufficient body is adjusted.

It should be noted that "early spring" can include part or all of "spring (from early April to the beginning of the rainy season)". In addition, part or all of "H. early winter (early December to end of December)" can be included in early autumn. The current date and month are managed by the clock function of the timer 9 .

The room temperature is the indoor temperature, and is always measured by the thermometer 7 (including when the air conditioner 4 is off).

Poor physical condition during the seasonal transition period is thought to occur because the body's thermal sensitivity cannot keep up with changes in temperature (temperature fluctuations) during the seasonal transition period (causes lag) due to changes in basal metabolism. Such a discrepancy between temperature and thermal sensitivity is unavoidable due to the fact that basal metabolism changes with a delay after temperature changes are felt, and that it is difficult to completely match basal metabolism to temperature changes. is.

The lower limit temperature 41 is the threshold temperature for starting the automatic heating operation. The lower limit temperature 41 is set to a temperature that triggers poor physical condition (for example, a temperature at which the room temperature is slightly insufficient) in the seasonal transition period, or is set to be as close to that temperature as possible. The lower limit temperature 41 can be obtained statistically, for example, as a temperature at which many people are likely to become ill.

For the lower limit temperature 41, for example, a numerical value obtained statistically is set in advance as an initial setting value in (the memories 27 and 32 of) the air conditioning control device 6 and the operation unit 5, and the initial setting value is used throughout the year. can be done.

Further, the lower limit temperature 41 may be arbitrarily adjusted/changed within a predetermined range around the initial setting value according to the user's preference. Thereby, the user can optimally adjust the lower limit temperature 41 to match his/her physical condition.

In this embodiment, the lower limit temperature 41 is set, for example, so that the initial set value is 17° C. to 18° C. and can be changed up to ±5° C. in 1° C. intervals. However, the above is an example, and the lower limit temperature 41 is not limited to the above. Then, for example, when the lower limit temperature 41 is set to 18° C., the heating operation is automatically started when the room temperature drops below 18° C. before the wake-up time.

The case where the room temperature is lower than the lower limit temperature 41 means that the room temperature is lower than the lower limit temperature 41 . Control when the room temperature falls below the lower limit temperature 41 may be performed by either (room temperature<lower limit temperature 41) or (room temperature≦lower limit temperature 41). The determination as to whether or not the room temperature has fallen below the lower limit temperature 41 may be made, for example, on the condition that the above relationship is established continuously for a certain period of time. The certain period of time may be, for example, one minute, or may be the period of time until the number of times the judgment is established reaches a predetermined number, or it may be the longer of the two.

Regardless of whether the power (power switch 28) is on or off means that the heating operation is forcibly performed regardless of whether the power of the air conditioner 4 is on or off. Since the automatic heating operation is already performed when the power is on, it is a particularly effective function when the power is off and heating is not being performed.

It is preferable that the automatic heating operation is operated at the heating set temperature 42 for a certain period of time (for example, a predetermined automatic operation period of about 2 to 4 hours) and automatically stopped after a certain period of time. . When there is a user's operation (for example, temperature change or stop operation) during automatic heating operation, the user's operation is given priority and the automatic heating operation is switched to the operation according to the user's operation. is preferred. The user's operation may be learned by AI and used to improve the accuracy of automatic heating operation. After that, it is preferable to repeat the automatic heating operation each time the room temperature falls below the lower limit temperature 41 .

The heating set temperature 42 may be set at any number as long as it is higher than the lower limit temperature 41. For example, during periods when heating is used on a daily basis (for example, A. Midwinter) before entering the seasonal transition period. It is preferable to be able to use the normal heating setting as it is as a reference value. This saves the user the trouble of inputting the heating temperature setting 42 (for automatic heating operation). The set temperature of this normal heating is the optimum room temperature for the user who spent the coldest period comfortably before the transition period, and the temperature differs for each user. Therefore, the set temperature for normal heating is not likely to cause poor physical condition even during the automatic heating operation to prevent poor physical condition, which is performed during the seasonal transition period, and is effective for obtaining the optimum room temperature for the user. standard value.

In general, there is a tendency that heating is not used so much during the transition period of the seasons, but the set temperature for normal heating is stored in (the memories 27 and 32 of) the air conditioning control device 6 and the operation unit 5 as settings. Since it is set, it can be used as a reference value by reading the setting as it is even during the transition period of the season.

For the heating temperature setting 42, the above-described reference value may be used as it is, but the user may adjust and change it to suit himself/herself. For the heating temperature setting 42, the setting for normal heating may be modified while the automatic heating operation is being performed, or the setting for the automatic heating operation may be changed separately from the normal heating setting. It may be prepared as a dedicated setting for the purpose so that the setting and modification can be performed at any time. The heating set temperature 42 may be changeable up to ±5° C. with an adjustment width of 1° C. interval, for example. Setting changes by the user may be learned by AI and used to improve the accuracy of automatic heating operation.

Specifically, for example, when the lower limit temperature 41 is set to 18° C. and the heating setting temperature 42 is set to 22° C. and automatic operation is performed, during the season transition period, when the room temperature becomes 18° C. or less Heating is automatically performed so that the room temperature is 22°C, and the user can change the heating set temperature 42 to, for example, 21°C or 23°C at any time.

(2) In the above, the air conditioning control device 6 corrects at least one of the lower limit temperature 41 and the heating set temperature 42 based on the cold index associated with poor physical condition in the transition period of the seasons during automatic heating operation. may be performed.

Here, a typical example of poor physical condition during the seasonal transition period is a cold.

The cold-catching index is an index that indicates a situation in which a person is likely to catch a cold, and is a good measure of how chilly the human body feels. And chilliness causes poor physical condition such as a cold. The cold index is represented by a numerical value from 0 to 100, for example.

The cold index can be used to specifically grasp the degree of chilliness from its value. The index for catching a cold is an objective numerical value, and was created with the idea that the susceptibility to catching a cold can be understood from the numerical value. , is highly correlated with temperature fluctuations, and is the most appropriate value to represent poor physical condition during the transition period between seasons. Therefore, this cold index is used to correct the lower limit temperature 41 and the heating set temperature 42 . The cold index is calculated, for example, by the air conditioning control device 6 or the operation unit 5 all the time or timely (for example, at least once a day or more).

For the cold index, for example, the latest information (data of the day, forecast data, etc.) is always published by external organizations such as the Japan Meteorological Agency and private weather companies. Therefore, the cold index can be obtained relatively easily. The higher the index of catching a cold, the easier it is to catch a cold. Details of the cold index will be described later.

Also, the difference between the change in temperature and the change in basal metabolism in the transitional period of the seasons changes the way we feel temperature (thermal sensitivity), so even if the temperature is the same, we feel hot or cold. Therefore, the lower limit temperature 41 that triggers poor physical condition also changes. Correction is required in order to adapt to changes in the lower limit temperature 41 and the like.

Correction is performed to adjust at least one of the lower limit temperature 41 and the heating set temperature 42 to match the conditions of the time and day. By correcting the lower limit temperature 41, the timing of starting the automatic heating operation is optimally adjusted to match the day of the season. Further, by correcting the heating set temperature 42, the room temperature by automatic heating is optimized for that day in that season.

Statistically and empirically, the standard of comfortable living temperature for general adults is as follows.
comfort temperature
Winter 18-22℃
Summer 25-28℃
In the case of babies and the elderly, it is recommended that the temperature should be raised by 1-2°C in winter and lowered by 1-2°C in summer.

According to the above, the comfortable temperature range is roughly between 4°C. It can be seen that the lower limit temperature 41 should be set around 18° C., which is the lower comfortable temperature in winter. Also, it seems highly likely that the heating set temperature 42 will be set around 22° C., which is the higher value of the comfortable temperature in winter. Therefore, the correction is, for example, as follows.

Specifically, when the lower limit temperature is set to 41:18°C and the heating setting temperature is set to 42:22°C, since people are accustomed to the cold weather in early spring, they do not feel cold even if the room temperature is slightly lower. The automatic heating operation starts at a low temperature, and corrects the lower limit temperature 41 to 17° C. and the heating set temperature 42 to 21° C., for example, so that the room temperature does not become too high.

In addition, if you set the lower limit temperature to 41: 18°C and the heating setting temperature to 42: 22°C, you will feel cold even if you raise the room temperature a little because you are not accustomed to the cold in early autumn. The heating operation starts at a higher temperature, and the lower limit temperature 41 is corrected to 19° C. and the heating set temperature 42 is corrected to 23° C., for example, so that the room temperature becomes slightly higher.

By correcting the lower limit temperature 41 and the heating set temperature 42 in this way, the automatic heating operation is adjusted to match the slight temperature changes of the day and the season, so that the user can always obtain a comfortable room temperature. However, since the above is an example, the correction is not limited to the above, and depending on the situation of the day and time, it may not be corrected, or it may be operated at a higher temperature in early spring and at a lower temperature in early autumn. It may be corrected as follows.

(3) In the above, in the air conditioning system 2,
The lower limit temperature 41 may be a daily value preset using the operation unit 5 .
The index for catching a cold may be the daily value obtained by converting at least two of the sensible temperature, the monthly basal metabolism, the minimum humidity, the daily temperature difference, and the previous day's temperature difference into points and adding them. .
The lower limit temperature 41 and the heating set temperature 42 may be corrected with correction values 41a, 41b and correction values 42a, 42b (FIG. 4) assigned to each rank by ranking cold-catching indices.

Here, the daily value of the lower limit temperature 41 means that the same value of the lower limit temperature 41 is used throughout the day, or that the lower limit temperature 41 is treated as a valid value only for one day. However, if the processing capacity of the device has a margin, the lower limit temperature 41 is valid only for a shorter period of time (for example, every half day, every unit time (1 hour to several hours), etc.). You may use it by updating it one by one. In this case, "value for each day" should be read as "value for each hour".

As described above, for the lower limit temperature 41, a reference value that is effective all year round is prepared in advance, and the reference value can be arbitrarily adjusted and changed within a predetermined range according to the user's preference and judgment of the day. . Therefore, the user may operate the lower limit temperature 41 with the reference value as it is, or may adjust it according to the user's preference and then leave it alone, or may frequently change it according to the situation. You can do it. Then, the lower limit temperature 41 (reference value or user's adjusted value) is corrected and updated at least daily by the cold index. As a result, the lower limit temperature 41 is a value valid only for one day at the longest.

The cold-catching index is an index that expresses the likelihood of catching a cold using five elements: sensible temperature, monthly basal metabolism, minimum humidity, temperature difference between days, and temperature difference on the previous day. Details of each element will be described later.

Outdoors, it is intuitively understood that the susceptibility to catching a cold is most influenced by the sensible temperature, but indoors, the minimum humidity and daily temperature difference affect the susceptibility to catching a cold more than the sensible temperature. greatly affect the This can be understood from the fact that people are more likely to catch a cold on days when the humidity is low, and people are more likely to catch a cold on days when the temperature fluctuates significantly during the day. Therefore, in the case of indoors, the minimum humidity and daily temperature difference are relatively important factors. Therefore, at the very least, it is possible to perform correction using only the minimum humidity and daily temperature difference.

On the other hand, indoors, the sensible temperature and the previous day's temperature difference have a lower effect on the susceptibility to catching a cold than the minimum humidity and the daily temperature difference. There was a tendency for the influence of (sensible temperature and temperature difference on the previous day) to increase.

Therefore, when we investigated the correlation of each of these elements by collecting specific data, we found that when the conditions of "sensible temperature is 15°C or higher and temperature difference from the previous day is less than -3°C" are not met, it is possible to catch a cold. It was also confirmed that when the conditions of "a daily temperature difference of less than 8°C and a minimum humidity of 50% or more" are not satisfied, it is easy to catch a cold. Therefore, the index for catching a cold is used for correcting the lower limit temperature 41 and the heating set temperature 42 based on such survey results.

The five elements of the cold-catching index are described below.

The sensible temperature is a numerical representation of the temperature sensation actually felt by the body, and varies depending on various environmental factors such as wind speed, solar radiation, and humidity. The sensible temperature can be obtained, for example, as a value (T−4√V (maximum wind speed)) obtained by subtracting the body temperature taken away by the wind from the temperature. This sensible temperature can be obtained from the data of the thermometer 7 and the speedometer. In this case, a sensible temperature of 15° C. or higher is the standard for catching a cold. When the sensible temperature is less than 15°C, it becomes easy to catch a cold.

Monthly basal metabolism summarizes changes in basal metabolism throughout the year and gives points for each month. For the monthly basal metabolism, the predetermined points for that month are used as they are. For example, April is all 0 points, May is all -3 points, and so on.

Minimum Humidity is the minimum value of humidity during the day. The minimum humidity can be obtained from the data of the hygrometer 8. A minimum humidity of 50% or more is the standard for catching a cold. When the minimum humidity is less than 50%, it becomes easy to catch a cold, and the lower the humidity is below 50%, the more likely it is to catch a cold, so the points increase.

The daily temperature difference is the temperature difference during the day, and is the difference between the maximum temperature and the minimum temperature of the day (maximum temperature - minimum temperature). The daily temperature difference can be obtained from the data of the thermometer 7 . A daily temperature difference of less than 8°C is the standard for catching a cold. When the daily temperature difference is 8°C or more, it becomes easy to catch a cold.

The previous day's temperature difference is the temperature difference between the previous day and the current day, and is the difference between the maximum temperature of the previous day and the maximum temperature of the current day (maximum temperature of the current day - maximum temperature of the previous day). The previous day's temperature difference can be obtained from the data of the thermometer 7 . A temperature difference of less than -3°C from the previous day is the standard for catching a cold. When the difference in temperature from the previous day is -3°C or higher, it is easy to catch a cold.

Then, by totaling the points of each element, a cold index can be obtained. The higher the point of the cold index, the easier it is to catch a cold.

In addition to calculating the cold index each time using the points described above, for example, the air conditioning control unit 6 can prepare list data in advance so that the points of the cold index can be roughly understood from the temperature and humidity. or stored in the memories 27 and 32 of the operation unit 5, and the stored table data may be used to derive the cold-catching index directly from the relationship between the temperature of the thermometer 7 and the humidity of the hygrometer 8. By using the table data in this way, the target temperature to be heated is also shown in the table at the same time, so both the lower limit temperature 41 and the heating set temperature 42 can be easily corrected.

Further, the cold index may be calculated using an external cloud service instead of being directly calculated by the air conditioning control device 6, or may be used by directly downloading external weather data. As described above, the latest information on the cold index is always published by external organizations such as the Japan Meteorological Agency and private weather companies, so data for the area may be obtained from these external organizations at any time and used. In this case, the air conditioning control device 6 and the operation unit 5 connect to an external cloud service via a network, or connect to an external organization or another external organization that handles data from the external organization. External data can be received in real time by providing the communication unit 25 for the purpose. In addition, when external data is received and used, forecast data (for the previous day) can be used in addition to the data for the current day. Alternatively, the latest data can be retrieved and used each time the data is updated. Also, these external data and internally calculated data can be used in combination.

The ranking of the cold index can be divided into multiple stages, for example, five stages. The cold-catching index is evaluated, for example, in the following five stages.
Rank 5. Caution level (from 18 points)
Rank 4. Alert level (14-17 points)
Rank 3. Caution level (9-13 points)
Rank 2. Attention level ( 4-8 points)
Rank 1. Hard to draw (0 to 3 points)
The items for ranking may be, for example, five levels of "danger", "severe caution", "warning", "caution", and "safety".

However, the ranking is not limited to five stages, and may be three stages or more. Also, the boundary value for each rank can be determined as appropriate. The rank order may be reversed.

The correction values 41a, 41b and 42a, 42b are set to 0.5° C. to 1.0° C. according to the rank of the index of catching a cold, and are increased or decreased. When correcting both the lower limit temperature 41 and the heating set temperature 42, it is preferable to use the same correction values 41a, 42a and 41b, 42b.

For example, the relationships between the ranks and the correction values 41a, 41b and 42a, 42b are as follows.
Rank 5 (warning level) → ±1°C
Rank 4 (alert level) → ±1°C
Rank 3 (Caution level) → ±0.5℃
Rank 2 (Caution level) → ±0.5℃
Rank 1 (hard to pull) → 0℃

Correction values 41a, 41b and 42a, 42b are differences for the immediately lower ranks. The correction values 41a, 41b and 42a, 42b are set to values such that the state of rank 1 is achieved by the automatic heating operation.

(4) In the above, in the air conditioning system 2,
A health mode button 51 (FIG. 2) may be provided on the operation unit 5 .
Only when the health mode button 51 is on, the air conditioning control device 6 may cause the air conditioning device 4 to perform the above-described automatic heating operation.

Here, the health mode button 51 is a selection switch for performing automatic heating operation. Each time the health mode button 51 is pressed, the heating operation may be automatically switched between on and off.

The lower limit temperature 41 and the heating set temperature 42 may be set after pressing the health mode button 51, or may be set at any time by preparing a dedicated temperature setting mode.

<Action> The action of this embodiment will be described below.

During the seasonal transition period, the basal metabolism changes greatly with temperature fluctuations, and the difference between the temperature fluctuations and the basal metabolism changes easily causes poor physical condition. However, during the seasonal transition period, we tend to let our guard down and endure unfavorable room temperatures without much use of heating or cooling. Therefore, by automatically heating the room during the seasonal transition period, it is possible to optimize the room temperature and prevent poor physical condition.

At this time, during the transition period of the seasons, changes in basal metabolism change the way we perceive temperature (heat sensitivity). Depending on the time of year, the temperature at which people want heating also changes.

Therefore, if the heating temperature setting 42 remains constant throughout the year, dissatisfaction such as "heating is not turned on even though I want it" or "heating is turned on even though I don't need it" is likely to occur. And it leads not only to dissatisfaction, but also to the cause of poor physical condition.

Therefore, it is desirable to eliminate such dissatisfaction when performing automatic heating operation to prevent poor physical condition during the seasonal transition period.

<Effects> According to this embodiment, the following effects can be obtained.

(Action and Effect 1) During the seasonal transition period, when the room temperature falls below a preset lower limit temperature 41 that triggers poor physical condition, the air conditioning control device 6 forces the air conditioning device 4 to automatically perform heating operation. Then, the room temperature is raised to the desired heating set temperature 42 set by the user.

As a result, the room temperature is always managed so as not to fall below the lower limit temperature 41, and the room temperature is raised to and maintained at the user's own heating set temperature 42, allowing the user to adapt to temperature fluctuations during seasonal transitions. It is possible to automatically create an indoor environment in which poor physical condition is unlikely to occur due to the inability to keep up with changes in thermal sensitivity (or basal metabolism) of the user. Therefore, it is possible to eliminate a slight shortage of room temperature during the seasonal transition period and prevent poor physical condition caused by a slight shortage of room temperature.

At this time, by setting the room temperature to the heating set temperature 42 set by the user himself/herself, it is possible to automatically create an indoor environment that the user likes, thereby eliminating the user's dissatisfaction. Further, if the heating temperature setting 42 is set to the temperature setting for heating in winter, the user can save the trouble of setting the heating temperature setting 42 by himself/herself.

Therefore, even though the temperature difference is large and it is difficult to manage physical condition, it is easy to endure without using the heating during the transition period of the season. You can get your desired indoor environment. Moreover, it is possible to eliminate unrealistic, cumbersome, and time-consuming operations such as turning on the heating or diligently adjusting the room temperature each time when the room temperature is slightly insufficient. A healthy and comfortable indoor environment suitable for each house can be realized. Furthermore, when the room temperature is slightly insufficient, it automatically operates for a short period of time to eliminate the room temperature shortage, so energy consumption can be reduced.

If the room temperature is too low, the user turns on the heating himself, so the automatic heating operation of this embodiment is not necessary. It is also possible to prevent the room temperature from becoming too low.

(Effect 2) The heating temperature setting 42 of the automatic heating operation may be changed (corrected) according to the cold index of the day. As a result, it is possible to finely respond to changes in the way people feel about temperature according to the weather conditions of the day.

Also, the lower limit temperature 41 may be changed (corrected) according to the cold index of the day. As a result, the timing for starting the automatic heating operation can be optimally adjusted (advanced or delayed) according to the weather conditions of the day.

Moreover, by performing correction using the index for catching a cold, the user can save the trouble of manually changing and adjusting the lower limit temperature 41 and heating set temperature 42 according to the conditions of the day.

Therefore, by automatically correcting the lower limit temperature 41 and heating setting temperature 42 using the cold index, it is possible to prevent poor physical condition when actually feeling "chilly" or "heating". It is possible to create a comfortable indoor environment that does not make you feel chilly by automatically performing heating operation for the sake of comfort. can. In addition, it is possible to eliminate dissatisfaction with heating for each user due to changes in how they perceive temperature without much effort.

(Effect 3) The lower limit temperature 41 may be used as a daily value. As a result, the automatic heating operation can be performed at the optimal timing for the day.

A value for that day may be used as the cold index. As a result, the lower limit temperature 41 and the user's heating temperature setting 42 can be corrected according to the conditions of the day.

By correcting the lower limit temperature 41 and the heating setting temperature 42 by the temperature assigned to each rank of the cold index, the correction is facilitated, and fine adjustments are made according to the subtle daily temperature fluctuations during the seasonal transition period. Corrections can also be made.

Therefore, it is possible to correctly judge whether it is necessary on that day or at that time, and if it is actually necessary, even if the air conditioner 4 is turned off, it is adjusted to suit that day or at that time to prevent poor physical condition. It is possible to have automatic heating operation for

(Effect 4) A health mode button 51 may be provided in the operation unit 5 of the air conditioner 4 so that the heating operation is automatically performed only when the health mode button 51 is turned on. As a result, the user only needs to operate the health mode button 51 provided on the operation unit 5 once for the first time, and after that, without being particularly conscious of it, automatic heating operation is performed to prevent poor physical condition during the transition period of the seasons. can be performed continuously. Also, by turning off the health mode button 51, the user can choose not to use the automatic heating operation.

<Construction> The construction of this embodiment will be described below.

The air conditioning system 2 including the air conditioner 4 that adjusts the room temperature, the operation unit 5 that operates the air conditioner 4, and the air conditioning controller 6 that controls the air conditioner 4 by operation from the operation unit 5 is described above. Same as example.

Furthermore, the air conditioning system 2 includes a thermometer 7 for measuring room temperature, a hygrometer 8 for measuring indoor humidity, a timer 9, a setting unit 11 for setting temperature, and other configurations. It is the same as the above embodiment.

(2-1) In the air conditioning system 2 of this embodiment, as shown in FIG.
When the room temperature and indoor humidity exceed the preset upper limit temperature and humidity 61 that trigger poor physical condition during the transition period from spring to summer through the rainy season or from summer to autumn,
The air conditioning control device 6 automatically starts the cooling operation of the air conditioning device 4 to lower the room temperature to the user's cooling set temperature 62 regardless of whether the power (power switch 28) is on or off.

Here, the seasons and the seasonal transition periods are the same as in the above-described embodiment.

The transition period from spring to summer through the rainy season is mainly "D. rainy season (the beginning of the rainy season to the end of the rainy season)" before summer. Also, the seasonal transition period from summer to autumn is mainly "F. early autumn (late August to end of September)" at the beginning of autumn.

In this embodiment, the periods in which cooling is not often performed are mainly "D. rainy season (the beginning of the rainy season to the end of the rainy season)" before summer and "F. early autumn (late August to the end of September)" in early autumn. The heat balance of the surplus body is adjusted by automatically performing the cooling operation.

It should be noted that "before summer" can include part or all of "C. Spring (from early April to the beginning of the rainy season)" and "E. Midsummer (from the end of the rainy season to late August)." Early autumn can include part or all of "E. midsummer (from the end of the rainy season to the end of August)". The current date and month are managed by the clock function of the timer 9 .

The room temperature and indoor humidity are indoor temperature and indoor humidity, and are always measured by thermometer 7 and hygrometer 8 (including when air conditioner 4 is off).

Poor physical condition during the seasonal transition period is the same as in the above example.

The upper temperature/humidity limit 61 is a threshold temperature for starting an automatic cooling operation, and is a temperature value associated with humidity. Even at the same temperature, the perception of heat changes depending on the humidity. The upper limit temperature and humidity 61 are set so as to be the temperature and humidity that trigger poor physical condition (for example, the temperature and humidity that make the room feel slightly overheated) during the seasonal transition period, or as close as possible to the temperature and humidity. is set to be The upper temperature/humidity limit 61 can be statistically obtained, for example, as the temperature and humidity at which many people are likely to become ill.

For the upper limit temperature and humidity 61, for example, numerical values obtained statistically are set in advance as initial setting values in the air conditioning control device 6 and the operation unit 5 (the memories 27 and 32 thereof), and the initial setting values are used throughout the year. be able to.

Further, the upper limit temperature and humidity 61 may be arbitrarily adjusted/changed within a predetermined range around the initial setting value according to the user's preference. Thereby, the user can optimally adjust the upper limit temperature/humidity 61 to match his/her physical condition.

In this embodiment, the upper limit temperature/humidity 61 is, for example, set so that the initial set value is equivalent to 28° C. to 29° C. (55%) and can be changed up to ±5° C. in 1° C. intervals. However, the above is an example, and the upper limit temperature/humidity 61 is not limited to the above. For example, if the upper limit temperature/humidity 61 is set to 28°C (55%), when the room temperature and indoor humidity reach 28°C (55%) or higher during the day, the cooling operation automatically starts. It will be done.

When the room temperature and room humidity exceed the upper limit temperature and humidity 61 , the room temperature is higher than the upper limit temperature and humidity 61 and the room humidity is higher than the upper limit temperature and humidity 61 . Alternatively, it is exceeding the temperature or humidity corresponding to the upper limit temperature and humidity 61 . When the room temperature and indoor humidity exceed the upper limit temperature and humidity 61, the control is either (upper limit temperature and humidity 61 < (room temperature, indoor humidity)) or (upper limit temperature and humidity 61 ≤ (room temperature, indoor humidity)). you can go Whether or not the room temperature or the indoor humidity exceeds the upper limit temperature and humidity 61 may be determined, for example, on the condition that the above relationship is established continuously for a certain period of time. The certain period of time may be, for example, one minute, or may be the period of time until the number of times the judgment is established reaches a predetermined number, or it may be the longer of the two.

Regardless of whether the power (power switch 28) is on or off means that the cooling operation is forcibly performed regardless of whether the power of the air conditioner 4 is on or off. Since the automatic cooling operation is already performed when the power is on, it is a particularly effective function when the power is off and no cooling is being performed.

It is preferable that the automatic cooling operation is performed at the cooling set temperature 62 for a certain period of time (for example, a predetermined automatic operation period of about 2 to 4 hours) and automatically stopped after a certain period of time. . If there is a user's operation (for example, temperature change or stop operation) during automatic cooling operation, the user's operation is given priority and the automatic cooling operation is switched to the operation according to the user's operation. is preferred. The user's operation may be learned by AI and used to improve the accuracy of automatic cooling operation. It is preferable to repeat the automatic cooling operation every time the room temperature exceeds the upper limit temperature/humidity 61 thereafter.

The cooling set temperature 62 should be lower than the upper limit temperature/humidity 61. For example, the normal cooling during the period when cooling is used on a daily basis (e.g. midsummer) before entering the season transition period. It is preferable to use the setting of as it is as a reference value. This saves the user the trouble of inputting the cooling set temperature 62 (for automatic cooling operation). The set temperature of this normal cooling is the optimum room temperature for the user who spent the hottest season comfortably before the transition period, and the temperature differs from user to user. Therefore, the set temperature of the normal cooling is not likely to cause poor physical condition even in the automatic cooling operation for preventing poor physical condition during the seasonal transition period, and is effective for obtaining the optimum room temperature for the user. standard value. In addition, since dehumidification is performed during cooling, the humidity is appropriately adjusted by the cooling.

In general, there is a tendency that cooling is not used much during the transition period of the seasons, but the normal cooling set temperature is stored in the air conditioning control device 6 and the operation unit 5 (the memories 27 and 32 thereof) as settings. Since it is set, it can be used as a reference value by reading the setting as it is even during the transition period of the season.

For the cooling set temperature 62, the above-described reference value may be used as it is, but the user may adjust and change it to suit himself/herself. The cooling set temperature 62 may be set for normal cooling while the setting for automatic cooling operation is being performed, or may be set for automatic cooling operation separately from the setting for normal cooling. It may be prepared as a dedicated setting for the purpose so that the setting and modification can be performed at any time. The cooling set temperature 62 may be changeable up to ±5° C. in 1° C. intervals, for example. The setting change by the user may be learned by AI and used to improve the accuracy of automatic cooling operation.

Specifically, for example, when the upper limit temperature and humidity 61 is set to 28° C. (humidity of 55%) and the cooling set temperature 62 is set to 25° C., automatic operation is performed. (humidity of 55%) or higher, cooling is automatically performed so that the room temperature reaches 25°C, and the user can set the cooling set temperature 62 to, for example, 24°C or 26°C at any time. can be changed.

(2-2) In the above, the air conditioning control device 6, during the automatic cooling operation, determines the upper limit temperature/humidity 61 and at least one of the cooling set temperature 62 may be corrected.

Here, poor physical condition in the seasonal transition period includes, for example, hot weather, summer cold, heat stroke, and the like. These poor physical conditions are caused by discomfort due to hot and humid weather and heat.

The discomfort index is mainly an index of hot and humid weather, and is a good measure of the discomfort felt by the human body. The hot and humid weather is an unpleasant feeling that tends to cause poor physical condition (for example, hot weather, summer cold, etc.) that tends to occur during the transition period of the seasons.

Since the feeling of hot and humid weather differs depending on race, ethnicity, region, etc., it is necessary to appropriately adjust the handling of numerical values when using the discomfort index according to race, ethnicity, region, etc.
For example, in the case of Japanese people, it is known that the relationship between the discomfort index and how they perceive the heat and humidity is as follows (ranked).

Discomfort index How it feels Less than 55 Cold 55 or more and less than 60 Chilly 60 or more and less than 65 No feeling 65 or more and less than 70 Pleasant 70 or more and less than 75 Not hot 75 or more and less than 80 Slightly hot 80 or more and less than 85 Hot and sweaty 85 or more Hot and sweaty In addition, since 50 or less is too cold, the above is an evaluation of 50 or more. A "comfortable" state of 65 or more and less than 70 is the reference for control.

On the other hand, the heat index (WBGT value) is an index of the heat balance between the human body and the outside air (or an index incorporating three factors that greatly affect the heat balance of the human body: humidity, radiant heat, and temperature). used as an indicator of disease. Heat can cause health problems such as heat stroke.

The discomfort index and the heat index can be used to specifically grasp the discomfort such as hot and humid weather and the heat (risk level) that causes the risk of heatstroke. The discomfort index and heat index are objective values that can be easily calculated from room temperature and humidity. It is highly correlated with changes in thermal sensitivity of the body during the transition period between seasons and the deviation from temperature fluctuations, and is most suitable as a numerical value that expresses poor physical condition during the transition period of the seasons. Therefore, such discomfort index and heat index are used to correct the upper limit temperature/humidity 61 and the cooling set temperature 62 . The discomfort index and the heat index are calculated, for example, by the air conditioning control device 6 or the operation unit 5 all the time or timely (for example, at least once a day or more).

Note that the discomfort index is highly dependent on humidity and the heat index is highly dependent on temperature, so they do not indicate the same physical condition (or they are indicators of different types of physical condition). Therefore, either one of the discomfort index and the heat index may be used, or both may be used.

The upper limit temperature/humidity 61 and the cooling set temperature 62 may be corrected separately for the discomfort index and the heat index, or may be corrected for only one of them. By correction based on the discomfort index, cooling operation is performed to prevent poor physical condition due to discomfort (hot weather, summer cold, etc.). In addition, cooling operation is performed to prevent heatstroke by correction based on the heat index.

For the discomfort index and the heat index, for example, the latest information (data for the day, forecast data, etc.) is always published by external organizations such as the Meteorological Agency and private weather companies. Therefore, the discomfort index and heat index can be obtained relatively easily. The higher the discomfort index and the heat index, the easier it is to get sick. The details of the discomfort index and the heat index will be described later.

Also, the difference between the change in temperature and the change in basal metabolism in the transitional period of the seasons changes the way we feel temperature (thermal sensitivity), so even if the temperature is the same, we feel hot or cold. Therefore, the upper limit temperature that triggers poor physical condition also changes. Correction is required in order to adapt to changes in the upper limit temperature.

Correction is performed in order to adjust at least one of the upper limit temperature/humidity 61 and the cooling set temperature 62 to match the conditions of the season and the day. By correcting the upper limit temperature/humidity 61, the timing of starting the automatic cooling operation is optimally adjusted to match the day of the season. Further, by correcting the cooling set temperature 62, the room temperature by automatic cooling is optimized according to the day of the season.

Statistically and empirically, the temperature and humidity standards for comfortable living for general adults are as follows.
Comfortable temperature Humidity Winter 18-22°C 45-60%
Summer 25-28℃ 55-65%
In the case of babies and the elderly, it is recommended that the temperature should be raised by 1-2°C in winter and lowered by 1-2°C in summer.

According to the above, the comfortable temperature range is roughly between 4°C. Also, the range of humidity at the above temperatures is approximately between 15%. It can be seen that the upper limit temperature/humidity 61 should be set around 28° C. (55% humidity), which is the higher comfortable temperature in summer. Also, it seems highly likely that the cooling set temperature 62 will be set around 25° C., which is the lower comfortable temperature in summer. Therefore, the correction is as follows, for example.

Specifically, when the automatic operation is set to correspond to the upper limit temperature and humidity of 61:28 ° C (humidity 55%) and the cooling setting temperature is 62:25 ° C, before summer, the room temperature is Since it feels hot even if it is slightly lower, the automatic cooling operation starts at a lower temperature, and the room temperature is set to a little lower, for example, the upper limit temperature and humidity 61 is set to 27 ° C (humidity 55%), and the cooling set temperature 62 is corrected to 24°C.

Also, if you set the maximum temperature and humidity to 61:28°C (humidity 55%) and set the cooling temperature to 62:25°C, you will be accustomed to the heat in early autumn. Since it does not feel hot, the automatic cooling operation starts at a higher temperature, so that the room temperature is slightly higher. Correct to 26°C.

By correcting the upper limit temperature/humidity 61 and the cooling set temperature 62 in this way, the automatic cooling operation is adjusted to match the slight temperature changes of the day and the season, so that the user can always obtain a comfortable room temperature. . However, since the above is just an example, the correction is not limited to the above. could be modified to operate at .

(2-3) In the above, in the air conditioning system 2,
The upper temperature/humidity limit 61 may be a daily value preset using the operation unit 5 .
The discomfort index or heat index is a value that is periodically calculated by the air conditioning control device 6 using the following formula and room temperature (from the thermometer 7) and indoor humidity (from the hygrometer 8) data. can be
The upper limit temperature/humidity 61 and the cooling set temperature 62 may be corrected with correction values 61a, 61b and correction values 62a, 62b (FIG. 7) assigned to each rank by ranking the discomfort index or heat index.

Here, the daily value of the upper limit temperature/humidity 61 means that the same value of the upper limit temperature/humidity 61 is used throughout the day, or that the upper limit temperature/humidity 61 is treated as a valid value only for one day. . However, if the processing capacity of the device is sufficient, the upper limit temperature and humidity 61 can be set for a shorter period of time (for example, every half day, every unit time (1 hour to several hours), etc.). You may use it by updating it one by one with . In this case, "value for each day" should be read as "value for each hour".

As described above, for the upper limit temperature and humidity 61, reference values that are valid throughout the year are prepared in advance, and the reference values can be arbitrarily adjusted and changed within a predetermined range according to the user's preference and judgment on the day. there is Therefore, the user may operate the upper limit temperature/humidity 61 as the reference value, adjust it to his liking and then leave it alone, or change it frequently according to the situation. You can make it work. The upper limit temperature/humidity 61 (reference value or user's adjustment value) is corrected and updated at least every day by the discomfort index and the heat index. As a result, the maximum temperature/humidity 61 is valid only for one day at the longest.

The discomfort index is calculated using the following formula.
Discomfort index = 0.81 x temperature + 0.01 x humidity (0.99 x temperature - 14.3) + 46.3
The temperature and humidity used for calculation are those detected by the thermometer 7 and the hygrometer 8 .

The heat index is calculated using the following formula.
Heat index (WBGT) = (0.7 x natural wet bulb temperature) + (0.3 x black bulb temperature)

The natural wet-bulb temperature is the temperature indicated by the wet-bulb thermometer, which is lower than the temperature indicated by the ordinary thermometer 7 (dry-bulb thermometer). A wet bulb thermometer is a thermometer 7 whose bulb is wrapped in moist gauze.

Globe temperature is the temperature indicated by a globe thermometer and is used to measure the effects of radiant heat and air currents. A black ball thermometer (globe thermometer) is a thermometer 7 used to measure radiant heat from the surroundings, and measures the temperature at the center of a hollow sphere (black body) painted in matte black. is. The natural wet-bulb temperature and the black bulb temperature used for calculation are converted from those detected by the thermometer 7 and the hygrometer 8 and used.

In addition to calculating the heat index each time using the above formula, for example, list data (Fig. 6) can be created in advance so that the points of the heat index can be found from the temperature and humidity. and stored in the memories 27 and 32 of the air conditioning control device 6 and the operation unit 5, and the stored table data can be used to directly derive the heat index from the relationship between the temperature of the thermometer 7 and the humidity of the hygrometer 8. You can do it. By using the table data in this way, the target temperature to be cooled is also shown in the table, so both the upper limit temperature/humidity 61 and the cooling set temperature 62 can be easily corrected.

In addition, the discomfort index and the heat index may be calculated using an external cloud service instead of being directly calculated by the air conditioning control device 6, or may be directly downloaded and used from external weather data. good. As mentioned above, the latest information on the discomfort index and heat index is constantly published by external organizations such as the Japan Meteorological Agency and private weather companies. Also good. In this case, the air conditioning control device 6 and the operation unit 5 connect to an external cloud service via a network, or connect to an external organization or another external organization that handles data from the external organization. External data can be received in real time by providing the communication unit 25 for the purpose. Also, when external data is received and used, forecast data (for the previous day) can be used in addition to the data for the current day. Alternatively, the latest data can be retrieved and used each time the data is updated. Also, these external data and internally calculated data can be used together.

The ranking of the discomfort index and the heat index can be divided into multiple stages, for example, 5 stages and 4 stages.

In the case of the discomfort index, for example, the five ranks from "unbearably hot" to "comfortable" described above are used for evaluation (Fig. 6).
Rank 5. Unbearably hot (over 85)
Rank 4. Hot and sweaty (80 or more and less than 85)
Rank 3. Slightly hot (75 or more and less than 80)
Rank 2. Not hot (70 or more and less than 75)
Rank 1. Pleasant (65 or more and less than 70)
The value in parentheses is the value of the discomfort index.

In the case of the heat index, for example, the following four ranks are used for evaluation.
Rank 4. Danger (31°C or higher)
Rank 3. Strict vigilance (28°C or higher, less than 31°C)
Rank 2. Caution (over 25°C and under 28°C)
Rank 1. Caution (below 25°C)
Values in parentheses are heat index values. Note that "Rank 1. Caution" also includes "Hard to become". The items for ranking may be, for example, five stages such as "warning level", "warning level", "warning level", "warning level", and "safety".

However, the ranking is not limited to 5 stages or 4 stages, and may be 3 stages or more. Also, the boundary value for each rank can be determined as appropriate. The rank order may be reversed.

The correction values 61a, 61b and 62a, 62b are set to 0.5° C. to 1.0° C. according to the rank of the discomfort index and the heat index, and are increased or decreased. When correcting both the upper limit temperature/humidity 61 and the cooling set temperature 62, it is preferable to use the same correction values 61a, 62a and 61b, 62b.

The relationships between the ranks and the correction values 61a, 61b and 62a, 62b are, for example, as follows.
Rank 5 → ±1°C
Rank 4 → ±1°C
Rank 3 → ±0.5℃
Rank 2 → ±0.5℃
Rank 1 → 0℃

Correction values 61a, 61b and 62a, 62b are differences for the immediately lower ranks. The correction values 61a, 61b and 62a, 62b are set to values such that the rank 1 state is achieved by the automatic cooling operation.

(2-4) In the above, in the air conditioning system 2,
A health mode button 71 (FIG. 2) may be provided on the operation unit 5 .
Only when the health mode button 71 is turned on, the air conditioning control device 6 may cause the air conditioning device 4 to perform the above-described automatic cooling operation.

Here, the health mode button 71 is a selection switch for performing automatic cooling operation. Each time the health mode button 71 is pressed, the cooling operation may be automatically switched between on and off.

This embodiment may be provided as a function different from that of the above-described first embodiment, or may be provided in combination with the above-described first embodiment. In this case, the health mode button 71 may be provided separately from the one for the automatic heating operation, or may be combined into one and shared. In this case, depending on the number of times one health mode button 71 is pressed, automatic cooling operation, automatic heating operation, both of them, and off may be switched in order.

The upper limit temperature/humidity 61 and the cooling set temperature 62 may be set after pressing the health mode button 71, or may be set at any time by preparing a dedicated temperature setting mode.

<Action> The action of this embodiment will be described below.

During the seasonal transition period, the basal metabolism changes greatly with temperature fluctuations, and the difference between the temperature fluctuations and the basal metabolism changes easily causes poor physical condition. However, during the seasonal transition period, we tend to let our guard down and endure unfavorable room temperatures without much use of heating or cooling. Therefore, by automatically performing cooling during the seasonal transition period, the room temperature can be adjusted to prevent poor physical condition.

At this time, during the transition period of the seasons, the way we feel about temperature (thermal sensitivity) changes due to changes in basal metabolism. In the season when the heat and humidity eases, the temperature at which people want air conditioning also changes.

Therefore, if the cooling set temperature 62 remains constant throughout the year, the automatic cooling operation for preventing poor physical condition will not be turned on even though I want it. dissatisfaction such as And it leads not only to dissatisfaction, but also to the cause of poor physical condition.

Therefore, it is desirable to eliminate such dissatisfaction when performing automatic cooling operation to prevent poor physical condition during the seasonal transition period.

<Effects> According to this embodiment, the following effects can be obtained.

(Action and Effect 2-1) During the seasonal transition period, when the room temperature and indoor humidity exceed the preset upper limit temperature and humidity 61 that trigger poor physical condition, the air conditioning controller 6 automatically causes the air conditioner 4 to The room temperature is lowered to the desired cooling set temperature 62 set by the user by forcibly performing the cooling operation.

As a result, the room temperature and indoor humidity are always managed so as not to exceed the upper limit temperature and humidity 61, and the room temperature is lowered to the user's own cooling set temperature 62 and maintained. It is possible to automatically create an indoor environment in which poor physical condition is unlikely to occur when the body's thermal sensitivity (or basal metabolism) cannot keep up with fluctuations, without the user noticing it. Therefore, it is possible to eliminate a slight excess room temperature during the seasonal transition period and prevent poor physical condition caused by a slight excess room temperature.

At this time, by setting the room temperature to the cooling set temperature 62 set by the user himself/herself, it is possible to automatically create an indoor environment preferred by the user, thereby eliminating the user's dissatisfaction. Further, if the cooling set temperature 62 is set to the set temperature for use of cooling in summer, the user can save the trouble of setting the cooling set temperature 62 by himself/herself.

Therefore, despite the large changes in temperature and humidity, it is difficult to manage physical condition. A comfortable user-preferred indoor environment can be obtained. Moreover, it is possible to eliminate unrealistic, troublesome and time-consuming operations such as the user turning on the air conditioner or diligently adjusting the room temperature each time when the room temperature is slightly excessive. It is possible to realize a healthy and comfortable indoor environment suitable for each house. Furthermore, when the room temperature is slightly excessive, it automatically operates for a short period of time to eliminate the excessive room temperature, so energy consumption can be reduced.

In addition, when the room temperature is too high, the user turns on cooling by himself, so the automatic cooling operation of this embodiment is not necessary. It is also possible to prevent the room temperature from becoming too high.

(Effect 2-2) The cooling set temperature 62 of the automatic cooling operation may be changed (corrected) according to at least one of the discomfort index and the heat index of the day. As a result, it is possible to finely respond to changes in the way people feel about temperature according to the weather conditions of the day.

Also, the maximum temperature and humidity 61 may be changed (corrected) according to at least one of the discomfort index and the heat index of the day. As a result, the timing of starting the automatic cooling operation can be optimally adjusted (advanced or delayed) according to the weather conditions of the day.

Moreover, by performing correction using the discomfort index and the heat index, it is possible to eliminate the trouble of manually changing and adjusting the upper limit temperature/humidity 61 and the cooling set temperature 62 one by one according to the conditions of the day. .

Humidity is a typical cause of poor physical condition during the seasonal transition period, and the discomfort index is an index that indicates the humidity. By having the system operate automatically, in situations where people actually feel that it is hot and humid, or that they want air conditioning, the air conditioning is automatically operated to prevent physical discomfort, making the room comfortable without feeling hot and humid. environment, and conversely, when it is felt that "cooling is unnecessary", it is possible to prevent the cooling operation from being performed.

The heat index is also used as an index of heatstroke by expressing the heat balance (exchange of heat) between the human body and the outside air. By automatically correcting the temperature/humidity 61 and the cooling set temperature 62, in a situation where the danger of heat stroke is actually felt, automatic cooling operation is performed to prevent poor physical condition and the person is overheated. It is possible to create a comfortable indoor environment in which no sickness occurs. Further, dissatisfaction with cooling for each user due to changes in how they feel about temperature can be eliminated without much effort.

(Effect 2-3) The upper limit temperature and humidity 61 may be used as daily values. As a result, the automatic cooling operation can be performed at the optimal timing for the day.

The discomfort index or the heat index is calculated by the air conditioning control device 6 at all times (for example, every 10 minutes) (even while the power of the air conditioner 4 is off), so that it can be used at that time of the day. value can be obtained. By using the obtained discomfort index or heat index for that day or that time, the upper limit temperature/humidity 61 and the user's cooling set temperature 62 can be corrected to match the situation of that day or that time.

By correcting the upper limit temperature/humidity 61 and the cooling set temperature 62 by the temperature assigned to each rank of the discomfort index, the correction is facilitated, and fine adjustments are made to match subtle daily temperature fluctuations during the seasonal transition period. corrections can also be made.

Therefore, it is possible to correctly judge whether it is necessary on that day or at that time, and if it is actually necessary, even if the air conditioner 4 is turned off, it is adjusted to suit that day or at that time to prevent poor physical condition. It is possible to perform automatic cooling operation for

(Function and Effect 2-4) Even if a health mode button 71 is provided in the operation unit 5 of the air conditioner 4 and the cooling operation is automatically performed only when the health mode button 71 is turned on. good. As a result, the user only has to operate the health mode button 71 provided on the operation unit 5 once at the beginning, and after that, the user can automatically automatically prevent poor physical condition during the transition period of the seasons without being particularly conscious of it. It becomes possible to continuously perform the cooling operation. Also, by turning off the health mode button 71, the user can choose not to use the automatic cooling operation.
