Next, a method of determining the distribution ratio for each day within the operating month will be described by showing a concrete example.

When allocating the operating ratio, the distribution shown in FIG. 10 (A) is obtained from the difference between the ideal set temperature of the present month shown in FIG. 9 (A) and the monthly weather information of each month shown in FIG. 9 (B). Calculate the ratio. If it is summer, calculate the result of adding all the differences between the maximum temperature and the set temperature, and divide the temperature difference on each day by this calculation result (total temperature difference) to determine the operation distribution ratio for each day. To do. In FIG. 10A, the temperature difference is actually calculated based on the monthly weather information of July and the set temperature information.

After the temperature difference is calculated every day, the total temperature difference is calculated. At this time, it should be noted that the portion where the difference is a negative number must be excluded from addition. This is because if the temperature is lower than the set temperature, it is not necessary to operate the air conditioner 21 and it is necessary to exclude it from the operation target day. The total temperature difference calculated in this way and the temperature difference for each day are used to determine the operation distribution ratio for each day.

Next, in FIG. 10B, the operation distribution ratio is obtained by dividing the temperature difference for each day shown in FIG. 10A by the total temperature difference. In this example, the temperature was used to determine the operation distribution ratio, but in reality, other environmental factors such as relative humidity also affect the sensible temperature of humans. Adjustments may be made. In this way, the overall operation distribution ratio is determined for each day.

Further, the distribution ratio for each time is determined based on the weather information on the day of operation by the same method as described with reference to FIGS. In this embodiment, it is determined whether or not driving is required based on the hourly predicted temperature obtained from weather information and the like. In summer, if the temperature is lower than the set temperature, the air conditioner 21 is not operated during that time. Also, if it is higher than the set temperature, take out that time period,
The control temperature for the entire operation day is calculated by adding all the differences from the set temperature of the portion higher than the set temperature. The distribution ratio of each time zone is determined by dividing the difference between the set temperatures of each time zone by the control temperature of the entire operation day. FIG. 11 shows a table obtained by performing calculations based on this method.

The operation distribution ratio is determined by using the above method, and the air conditioner 21 is operated. In addition, the operation will be reviewed when there is a change in weather information, power rate unit price information, etc. and when the date changes. This judgment is made by comparing the latest weather information with the previous weather information using a communication means such as a telephone line or the Internet. If there is a change as a result of the comparison, the operation distribution ratio is recalculated based on new weather information, electric power unit price information, etc., and the operation plan of the air conditioner 21 is reviewed. In this embodiment, the review of operation is realized by periodically collecting and comparing weather information, power rate unit price information, etc., but if there is information update guidance etc. by the information provider, use this. You may go. In this way, in the first embodiment, it is possible to realize the operation schedule calculation and the review according to the change of the weather condition.
