  The past temperature information, past humidity information, and the ratio of sunshine hours per unit time may be provided by, for example, the Japan Meteorological Agency. When using the information provided by the Japan Meteorological Agency, of course, the one closest to the area where the target building exists is used.

Humidity) Past information and percentage information of sunshine hours per hour are recorded.

  The temperature sensor 11 and the humidity sensor 12 perform observation at regular intervals such as every 30 seconds and every 1 minute, and are installed outdoors.

Here, the meteorological-sunshine duration storage means 10 stores the past temperature information and humidity past information in unit time in a specific region and the proportion information of the sunshine duration per unit time in the specific region. It will be explained on the assumption that there is.

  First, the temperature sensor 11 and the humidity sensor 12 observe temperature and humidity at regular intervals.

  Next, the first data conversion means 13 captures observation results observed by the temperature sensor 11 and the humidity sensor 12, and converts the captured observation results into average temperature information and average humidity information per unit time.

  Next, the average temperature information and the average humidity information per unit time converted by the first data conversion unit 13 are stored in the actual information storage unit 14.

  Next, the sunshine duration estimating means 15 uses the past temperature information, the past humidity information, and the ratio of the sunshine duration per unit time stored in the weather-sunshine duration storage means 10 to obtain the actual information storage means. The ratio of the sunshine hours per unit time in the future is estimated from the average temperature information and the average humidity information stored in 14.

  Finally, the first output means 17 outputs the ratio of the sunshine hours per unit time stored in the first sunshine time storage means 16 to the device 18.

  Here, the estimation of the ratio of the sunshine hours per unit time performed by the sunshine time estimation means 15 will be described using a specific example. Here, using the information provided by the Japan Meteorological Agency, in 1996-2002, the past temperature information, humidity past information, and sunshine hours per hour from 8:00 to 16:00 in 1996-2002 Description will be made on the assumption that the ratio information is recorded in the weather-sunshine duration storage means 10.

  First, the past temperature information, the past humidity information, and the ratio information of the sunshine hours per hour stored in the weather-sunshine time storage means 10 are read out.

  Taking the ratio of humidity on the vertical axis and the temperature on the horizontal axis, and creating a graph using the read information, the temperature is 0 ° C. to 0 ° C., as shown in FIGS. It is dispersed in the range of 35 ° C., and the humidity is dispersed in the range of 9% to 100%.

  Next, the past temperature information and the past humidity information read out from the weather-sunshine time storage means 10 are either those with a high percentage of sunshine hours per hour or those with a low percentage of sunshine hours per hour. Sort out what is not.

  This selection is performed as follows, for example. First, in the range that the air temperature can take (in the above example, the range of 0 ° C. to 35 ° C.), the data is within the range of the lowest temperature range (5 ° C. ± 5 ° C.) and the highest temperature range (30 ° C. ± 5 ° C.). Is selected. Next, the selected data is further selected for each humidity zone in increments of 10%. Here, every 10% humidity band means, for example, a 10% band of 5% to less than 15%, a 20% band of 15% to less than 25%, a 30% band of 25% to less than 35%, 40% band from 35% to less than 45%, 50% band from 45% to less than 55%, 60% band from 55% to less than 65%, 70% band from 65% to less than 75%, 75% It means the 80% band of the above-less than 85% and the 90% band of the 85% or more-100% or less.

  Next, in the lowest temperature range, for example, data having a ratio of sunshine hours per hour of 90% or less (sunshine hours per hour 54 minutes or less) is selected. Then, a humidity band that is equal to or less than a certain percentage is calculated (in this specific example, if the certain percentage is set to 10%, for example, the calculated humidity band becomes 20%). The humidity zone calculated in this way is a guideline for separating a humidity zone where the sunshine time per hour is 54 minutes or less and a humidity zone where the sunshine time per hour is 54 minutes or more.

  Similarly, in the highest temperature range, for example, data having a ratio of sunshine hours per hour of 90% or less (sunshine hours per hour 54 minutes or less) is selected. Then, a humidity band that is equal to or less than a certain percentage is calculated (in this specific example, if the certain percentage is set to 10%, for example, the calculated humidity band is 50%). The humidity zone calculated in this way is a guideline for separating a humidity zone where the sunshine time per hour is 54 minutes or less and a humidity zone where the sunshine time per hour is 54 minutes or more.

Next, the median temperature in the lowest temperature zone (in this example, 5 ° C.), the humidity zone calculated in the lowest temperature zone (in this example, 20%), and the median temperature in the highest temperature zone (in this example) Then, a threshold line L2 is provided as shown in FIGS. 3A and 3B from the humidity range calculated in the highest temperature range (in this specific example, 50%) (in this specific example, Assuming that the relative humidity is y and the temperature is x, the threshold line L2 is expressed as y = (6/5) × x + 14). Data in the region below the threshold line L2 provided in this way has a high ratio of sunshine hours per hour. In this specific example, the slope of the threshold line L2 is 6/5 (hereinafter, the slope 6/5 of the threshold line L2 is abbreviated as a _fine ), and the intercept is 14 (hereinafter, the intercept 14 of the threshold line L2 is b _fine ). (Omitted).

  Next, in the lowest temperature range, for example, data having a ratio of sunshine hours per hour of 10% or more (6 hours or more of sunshine hours per hour) is selected. Then, a humidity band that is equal to or less than a certain percentage is calculated (in this specific example, if the certain percentage is set to 10%, for example, the calculated humidity band is 60%). The humidity zone calculated in this way is a standard for separating a humidity zone where the sunshine time per hour is 6 minutes or more and a humidity zone where the sunshine time per hour is 6 minutes or less.

  Similarly, in the highest temperature range, for example, select data with a rate of sunshine hours per hour of 10% or less (6 minutes or more of sunshine hours per hour). However, a humidity band that is equal to or less than a certain percentage is calculated (in this specific example, if the certain percentage is set to 10%, for example, the calculated humidity band is 90%). The humidity zone calculated in this way is a standard for separating a humidity zone where the sunshine time per hour is 6 minutes or more and a humidity zone where the sunshine time per hour is 6 minutes or less.

Next, the median temperature in the lowest temperature zone (in this example, 5 ° C.), the humidity zone calculated in the lowest temperature zone (in this example, 60%), the median temperature in the highest temperature zone (in this example) Then, a threshold line L1 is provided as shown in FIGS. 3A and 3B from the humidity zone calculated in the highest temperature zone (90% in this specific example) (in this specific example, relative Assuming that the humidity is y and the temperature is x, the threshold line L1 is expressed as y = (6/5) × x + 54). Data in the region above the threshold line L1 thus provided has a low rate of sunshine hours per hour. In this specific example, the slope of the threshold line L1 is 6/5 (hereinafter, the slope 6/5 of the threshold line L1 is abbreviated as a _cloudy ), and the intercept is 54 (hereinafter, the intercept 54 of the threshold line L1 is b _cloudy . (Omitted).

  As described above, the threshold lines L1 and L2 are used to select the case where the ratio of the daylight hours per hour is low, the case where the ratio of the daylight hours per hour is high, or neither of them.

Next, with respect to the threshold lines L1 and L2 that have become the selection criteria as described above, an estimation equation is obtained from the slope of the threshold line L1, the intercept of the threshold line L1, the slope of the threshold line L2, and the intercept of the threshold line L2. derive. In this estimation formula, the ratio of the sunshine hours per unit time in the future is Sr (0 ≦ Sr ≦ 1) [%], the relative humidity [%] is Rh, the temperature [° C.] is T, and the threshold line L1 When the slope is a _cloudy , the intercept of the threshold line L1 is b _cloudy , the slope of the threshold line L2 is a _fine, and the intercept of the threshold line L2 is b _fine , for example, when Rh ≦ a _fine × T + b _fine : Sr = 1,
a _fine × T + b _fine <Rh <a _cloudy × T + b _cloudy : Sr = −1 / ((a _cloudy × T + b _cloudy ) − (a _fine × T + b _fine )) × (Rh− (a _fine × T + b _fine )) +1,
When Rh ≧ a _cloudy × T + b _cloudy : Sr = 0
Define as follows. The estimation formula can be represented by a graph as shown in FIG.

When such an estimation formula is applied to the above specific example,
When Rh ≦ 6/5 × T + 14: Sr = 1
When 6/5 × T + 14 <Rh <6/5 × T + 54: Sr = −1 / ((6/5 × T + 54) − (6/5 × T + 14)) × (Rh− (6/5 × T + 14)) +1,
When Rh ≧ 6/5 × T + 54: Sr = 0,
It becomes.

  Then, the average temperature information and the average humidity information transmitted from the actual information storage unit 14 are substituted into the above estimation formula to determine the ratio of the sunshine hours per unit time in the future.

  For example, in the above specific example, when the average temperature information per hour transmitted from the actual information storage means 14 is 10 ° C. and the average humidity (relative humidity) information per hour is 20%, the above estimation formula Substituting T = 10 and Rh = 20 into Sr = 1. Therefore, when the average temperature information per hour is 9 ° C. and the average humidity (relative humidity) information per hour is 20%, the ratio of the sunshine hours per unit time in the future is 100%. In other words, under the above conditions, it is presumed that the sunlight was lit all the time.

  Further, in the above specific example, when the average temperature information per hour transmitted from the actual information storage means 14 is 10 ° C. and the average humidity (relative humidity) information per hour is 50%, the above estimation formula Substituting T = 10 and Rh = 50 into Sr = 0.40. Therefore, when the average temperature information per hour is 10 ° C. and the average humidity (relative humidity) information per hour is 50%, the ratio of the sunshine hours per unit time in the future is 40%. In other words, under the above conditions, it is estimated that sunlight falls for 24 minutes in one hour.

  Furthermore, in the above specific example, when the average temperature information per hour transmitted from the actual information storage means 14 is 10 ° C. and the average humidity (relative humidity) per hour is 70%, the above estimation formula Substituting T = 10 and Rh = 70 into Sr = 0. Therefore, when the average temperature information per hour is 10 ° C. and the average humidity (relative humidity) information per hour is 70%, the ratio of the sunshine hours per unit time in the future is 0%. In other words, under the above conditions, it is estimated that sunlight does not hit during one hour.

  In the specific examples described above, the setting of the unit time width: 1 hour, the ratio of the sunshine hours per hour: 10% and 90%, the existence ratio of the data serving as the threshold: 10%, etc. is merely an example. Absent.

  According to such a sunshine duration estimation device, weather-related information stored so as to correspond to past temperature information / humidity past information in unit time in a specific region and ratio information of sunshine duration per unit time in the specific region The sunshine duration storage means 10, the temperature sensor 11 and humidity sensor 12 for observing the weather, and the observation data from the sensors 11 and 12 are fetched at regular intervals, and the taken observation data is used as the average temperature information / average humidity per unit time. The first data conversion means 13 for converting to information, the actual information storage means 14 for storing the average temperature information and the average humidity information converted by the first data conversion means 13, and the weather-sunshine duration storage means 10 are stored. Using the average temperature information / average humidity information and the ratio of sunshine hours per unit time, the average temperature information / Since there is provided a daylight time estimation means 15 for estimating the percentage of sunshine per a future unit time than average humidity information, it is possible to estimate the duration of sunshine percentage per actual unit time.

  Therefore, since it is possible to maintain the current indoor temperature in anticipation of future sunshine hours, air that can maintain the indoor temperature to make it easier for people to live while suppressing energy consumption as much as possible. An adjustment device can be provided.

  Moreover, the first data conversion means 13 takes in observation results from the temperature sensor 11 and the humidity sensor 12 at regular intervals, and converts the taken observation results into average temperature information / average humidity information per unit time. It is possible to reduce the observation error and improve the reliability of the estimated sunshine duration rate per unit time.

  Furthermore, since the sensor is a thermometer and a hygrometer, and a special sensor such as a sunshine meter is not required, a sunshine amount estimation device with a low component cost can be provided.
