At first, CCU 80 be necessary to the running in all air-conditionings on distribute the electricity usage amount equably.The 210th stage be wherein a kind of method promptly, whether sequential control.The situation of sequential control should be selected to carry out according to the user.According to the sequential control in the 210th stage is for using all air-conditionings simultaneously, and the running ability of control air-conditioning reduces and carries out from present level.
If, be when controlling in order in above-mentioned the 210th stage, the 230th stage promptly, reduce the operation of air conditioner ability.The running ability of all air-conditionings in the running (that is, the output level) is reduced a stage control, so electrification is no more than the scope of afore mentioned rules current value.Therefore regulate all air-conditioning operating states according to the running ability of the air-conditioning in the 230th stage,, reach in the rated current scope that current value that transformer 50 detects sets in the 200th stage and operate from consuming the initial point of maximum power.
If, in the time of can not sequential control in above-mentioned the 210th stage, CCU 80 the part in all air-conditionings of operating state fix time in, stop to specify operation of air conditioner, make other air-conditioning continue running promptly, the 220th stage.In above-mentioned the 220th stage, only be in all air-conditionings of operating state an air-conditioning is controlled to be halted state for well.
In above-mentioned the 220th stage, the air-conditioning that stays cool, through the 240th stage promptly, whether passed through certain hour.If surpass the certain hour of setting, be controlled to be operating state again, at this moment other air-conditioning was controlled to be for the 250th stage promptly, and stopping next air-conditioning is halted state.In the control stage, the air-conditioning of halted state and the air-conditioning of operating state are changed repeatedly.
That is, 250 stages of the 220th stage to the maintain present state to the running ability (output level) that is in all air-conditionings of operating state, and sequence of operations (perhaps stopping order) is carried out variable control.
So control, the user who uses the multicell air-conditioning is no more than under the situation of scope the refrigerating/heating effect that obtains wishing at the load according to air-conditioning at power consumption.
The rated current that illustrates in the 200th stage of the present invention is set at the low electric current of setting than existing the 100th stage of rated current value.This is because existing rated current is to set under the scope that can not continue driving; In contrast, rated current design of the present invention is to drive in its scope.The calculation of the electricity charge that main is is a basic calculating with the peak electric weight surely, therefore the 200th stage rated current set low more, it is low more that the electricity charge also become.
In sum, the central management method characteristics of multicell air-conditioning of the present invention are when using many air-conditionings at the same time, and in the following scope of peak electric weight, CCU 80 is forced control, and air-conditioning can be in operating state.Particularly, the present invention reduces the output level of air-conditioning or repeatedly a part of air-conditioning is controlled to be halted state at certain hour, thereby has limited power consumption.
