Claim:
1. A control device comprising: a receiver that receives a control request signal, the control request signal indicating a request for controlling a total power amount consumed by an air conditioner during a predetermined period to be lower than or equal to a predetermined limit; an obtainer that obtains a power consumption amount consumed by the air conditioner; and a controller that causes the air conditioner to operate according to the control request signal received by the receiver, and controls the total power amount consumed by the air conditioner during the predetermined period to be lower than or equal to the predetermined limit, wherein the controller performs: determining a first time in the predetermined period, based on the power consumption amount obtained by the obtainer; causing the air conditioner to operate during a first period from a start of the predetermined period to the first time with power higher than average power calculated based on the predetermined limit and the predetermined period, after increasing the power consumed by the air conditioner to be higher than the average power; wherein the average power is power obtained by averaging the predetermined limit by the predetermined period; and causing the air conditioner to operate during a second period from an end of the first time to an end of the predetermined period with power lower than the average power, after decreasing the power consumed by the air conditioner to be lower than the average power, wherein the obtainer further obtains an outside air temperature and a room air temperature, and wherein the controller performs: calculating an upper limit according to the outside air temperature and the room air temperature, the upper limit being power for keeping the room air temperature in a predetermined range, the upper limit being power lower than the average power; and causing the air conditioner to operate during the second period with power lower than or equal to the upper limit, after decreasing the power consumed by the air conditioner to be lower than or equal to the upper limit.
