FIG. 11 is an explanatory diagram showing an example of the schedule of the environmental equipment control system according to this embodiment.
The environmental equipment control system according to this embodiment includes a schedule setting means 34 for operating target equipment at specified times.
FIG. 11 shows schedules set for air conditioning equipment 60, ventilation equipment 50, and lighting equipment 100.
For example, in the air conditioner 60 in summer, the temperature is 24°C from 8:30 to 9:00, 26°C from 9:00 to 12:00, 28°C from 12:00 to 13:00, and 28°C from 12:00 to 13:00. : 22℃ from 00 to 14:00, 25℃ from 14:00 to 18:00, 28℃ from 18:00 to 20:00, and stopped after 20:00. There is.
In addition, the air conditioner 60 in winter is 25°C from 8:30 to 9:00, 22°C from 9:00 to 12:00, 24°C from 12:00 to 13:00, and 24°C from 12:00 to 13:00. : 23℃ from 00 to 14:00, 22℃ from 14:00 to 18:00, 20℃ from 18:00 to 20:00, and stopped after 20:00. There is.
Further, the ventilation equipment 50 is set to operate at low speed from 8:30 to 22:00, and to stop after 22:00.
In the lighting equipment 100, the dimming rate is 70% from 8:30 to 9:00, the dimming rate is 80% from 9:00 to 12:00, and the dimming rate is 80% from 12:00 to 13:00. It shows that the light rate is set to 25%, the dimming rate is 80% from 13:00 to 18:00, the dimming rate is 70% from 18:00 to 22:00, and it is stopped after 22:00. .

When the schedule setting means 34 sets the set temperature of the air conditioner 60 by specifying the time, the control means 31 sets the set temperature according to the time period set by the schedule setting means 34 in the first air conditioning mode. In the second air conditioning mode, the set temperature is lowered depending on the time of day.
For example, in the setting of the air conditioner 60 in summer, from 13:00 to 14:00, the first air conditioning mode operates with a set temperature of 22°C, and the second air conditioning mode operates with a set temperature of 20°C. The temperature shall be 0°C.
In addition, in the setting of the air conditioner 60 in winter, from 13:00 to 14:00, the first air conditioning mode operates with a set temperature of 23.degree. C., and the second air conditioning mode operates with a set temperature of 21.degree. The temperature shall be 0°C.
In this way, according to this embodiment, it is possible to set an efficient temperature by setting a schedule, and even if a schedule is set, sensory stimulation according to the CO ₂ concentration can be generated based on the set temperature set in the schedule. can be given to others.
When the set temperature of the air conditioner 60 is set by time specification by the schedule setting means 34, the air conditioner 60 is operated at the set temperature according to the set time period even in the third air conditioning mode.

Further, when the schedule setting means 34 sets the operation of the ventilation equipment 50 by specifying the time, the control means 31 sets the ventilation equipment 50 to strong operation in the third ventilation mode, and sets the ventilation equipment 50 to strong operation in the fourth ventilation mode (weak operation). ), the ventilation equipment 50 is set to the weak operation set by the schedule setting means 34.
For example, in the settings of the ventilation equipment 50, between 8:30 and 22:00, if the third ventilation mode is entered, the ventilation equipment 50 is set to strong operation, and the fourth ventilation mode, which does not detect a person, is set. Also, the ventilation equipment 50 is set to a set weak operation instead of a weak operation.
As described above, according to this embodiment, a comfortable working environment is maintained by giving priority to the third ventilation mode over the schedule setting, and the ventilation equipment 50 is operated by giving priority to the fourth ventilation mode according to the schedule setting. Therefore, even if there are times when there are no people present, such as during working hours, by forcing the ventilation equipment 50 to operate, it is possible to cope with a sudden increase in the number of people. can.

Further, when the schedule setting means 34 sets the dimming rate of the lighting equipment 100 by specifying the time, the control means 31 controls the control means 31 to adjust the dimming rate according to the time period set by the schedule setting means 34 in the first lighting mode. In the second illumination mode, the illuminance of the lighting equipment 100 is increased or decreased at predetermined intervals by increasing the dimming rate depending on the time of day or at a dimming rate depending on the time of day.
For example, in the settings of the lighting equipment 100, between 8:30 and 9:00, the first lighting mode is set to 70%, which is the dimming rate according to the time period set by the schedule setting means 34, and In the second lighting mode, the dimming rate is increased to 100%, and in the first lighting mode, from 9:00 to 12:00, the dimming rate is set according to the time period set by the schedule setting means 34. 80%, and in the second lighting mode, the dimming rate is increased to 100%, and in the first lighting mode, from 13:00 to 18:00, according to the time period set by the schedule setting means 34. The dimming rate is set to 80%, and in the second lighting mode, the dimming rate is increased to 100%, and in the first lighting mode, from 18:00 to 20:00, the dimming rate is set by the schedule setting means 34. The dimming rate is set to 70% depending on the time of day, and in the second lighting mode, the dimming rate is increased to 100%.
In this way, according to this embodiment, it is possible to set efficient illuminance by setting a schedule, and even if a schedule is set, visual stimulation according to the CO ₂ concentration can be generated based on the dimming rate set in the schedule. can be given to others.
Note that, for example, as shown from 12:00 to 13:00, the second lighting mode can also be set to maintain the same dimming rate of 25% as the first lighting mode.

Further, when the schedule setting means 34 sets the dimming rate of the lighting equipment 100 by specifying the time, the control means 31 controls the schedule setting means 34 to set the dimming rate when the human sensor 11 does not detect a person. The third lighting mode is used instead of the dimming rate depending on the time of day.
For example, in the setting of the lighting equipment 100, between 18:00 and 22:00, the light control rate is not set to 70%, which is the dimming rate according to the time zone set by the schedule setting means 34, but the lighting device is stopped as the third lighting mode. do.
As described above, according to this embodiment, it is possible to set an efficient illuminance by setting a schedule, and even if a schedule has been set, it is possible to prevent forgetting to turn off the lighting equipment 100, and the system can be operated efficiently.

Further, in the third lighting mode, a preset dimming rate may be reduced instead of stopping. The dimming rate to be lowered may be a low dimming rate that is always constant, or may be a dimming rate that is reduced by a predetermined ratio depending on the time of day.
Here, always maintaining a constant low dimming rate means keeping the dimming rate at 25% regardless of whether the dimming rate is 75% or 80% depending on the time of day. If the dimming rate according to the time of day is 75%, it will be set to 25%, and if the dimming rate according to the time of day is 80%, then the dimming rate will be reduced by a predetermined ratio. If so, it shall be set at 30%.
For example, in the settings of the lighting equipment 100, between 8:30 and 9:00, the dimming rate is not 70%, which is the time period set by the schedule setting means 34, but is set to 25% as the third lighting mode. %, and between 9:00 and 12:00, the dimming rate is 25% as the third lighting mode instead of 80%, which is the dimming rate according to the time zone set by the schedule setting means 34. Between 13:00 and 18:00, the dimming rate is 25% as the third lighting mode, instead of 80%, which is the dimming rate corresponding to the time zone set by the schedule setting means 34. rate.
Note that, for example, when the dimming rate is set to a low dimming rate of 25% according to the time zone set by the schedule setting means 34, as shown in the period from 12:00 to 13:00. Alternatively, the third lighting mode may be set to maintain the set dimming rate of 25%.

Furthermore, the time set by the schedule setting means 34 is divided into a first time period and a second time period, and when no person is detected by the human sensor 11, the dimming rate is set to be low in the first time period, It is preferable to stop during the second time period.
For example, if the first time period is from 8:30 to 18:00 and the second time period is from 18:00 to 8:30 the next morning, the first time period During the period from 8:30 to 18:00, the third lighting mode is set to a dimming rate of 25%, and during the second time period, from 18:00 to 8:30 the next morning, the third lighting mode is set to 25%. 3. Stop as lighting mode.
Note that here, the first time slot is set as working hours and the second time slot is set as off-duty time, but it is also possible to set the second time slot all day long on Saturdays, Sundays, and public holidays.
Further, it is preferable that the control method divided into the first time period and the second time period be applied to other devices as well.
For example, in the settings of the ventilation equipment 50, if the first time period is from 8:30 to 22:00 and the second time period is from 22:00 to 8:30 the next morning. In the first time period, if weak is set in the schedule setting means 34, even if the fourth ventilation mode does not detect a person, the operation is performed as weak operation, and in the second time period, the fourth ventilation mode does not detect a person. 4 Even if the ventilation mode conditions are met, the scheduled shutdown will occur.
In addition, in the settings of the air conditioner 60, the first time period is set to 8:30 to 12:00 and 13:00 to 20:00, which are business hours, and the second time period is set to be non-business hours. When a certain time is set to 12:00 to 13:00, the first time period is the set temperature according to the time period set by the schedule setting means 34 in the first air conditioning mode, and the temperature is set according to the time period set by the schedule setting means 34 in the second air conditioning mode. Although the set temperature is lowered according to the time slot, the set temperature corresponding to the time slot set by the schedule setting means 34 is maintained during the second time slot even in the second air conditioning mode. Note that during the second time period, even if the condition of the third air conditioning mode in which no person is detected is reached, the set temperature according to the schedule is maintained.
