Abstract

PROBLEM TO BE SOLVED: To equalize power demand by elevating or lowering the set temperature of air conditioning in a facility equally in a specific time zone. SOLUTION: A schedule control section 1 monitors air conditioners to be turned on/off currently based on an operation schedule holding section 2. When an air conditioners is turned on, set values of an appointed day are taken out from a set value schedule holding section 3. Furthermore, an energy saving schedule holding section 4 and an energy saving set data holding section 5 are taken out and a decision is made whether current time of an appointed day correspond to the energy saving execution time. When it corresponds to the energy saving execution time, an energy saving set value is added to or subtracted from a normal set value and a resulting value is outputted as a set value. At the same time, the schedule control section 1 delivers a set value obtained by adding or subtracting an energy saving set value to or from a normal set value to all floors if current time corresponds to on time of energy saving mode.

In the case of the energy saving time zone, a value obtained by adding or subtracting the energy saving set value from the normal set value is output as the set value. If it does not correspond to the energy saving time zone, the value set in the set value schedule is output as it is. For example, the energy saving mode is set as shown in FIG. At the same time, the schedule control unit 1 constantly monitors whether the current time is the energy saving mode ON / OFF time,
If the time is the energy saving ON time, a value obtained by adding the energy saving set value (for example, 2 ° C.) to the normal set value (or subtracted value) is output as a set value for all floors (or devices). At the energy saving OFF time, the value set in the set value schedule 3 is output as it is. Thus, when the energy saving mode is ON, each floor (equipment)
The set temperature becomes the energy saving mode operation as shown in FIG. 8, and can be uniformly changed to suppress the energy consumption.
