In FIGS. 1 and 3, the central device 15 centrally controls and manages the operating status of each equipment including the air conditioners 3a to 31, but the amount of power used calculated by the amount of power calculation means 16c is When the number of operating devices exceeds the specified upper limit, the demand control means 15a that constantly monitors the amount of electricity determines this, and the central device 15 issues a demand control signal to once raise the set temperature during operation (70 o'clock). The information is then transmitted to the air conditioning controllers 7a to 71 and changes are made (at 11 o'clock). If a signal indicating that the air conditioner has stopped is not sent from the air conditioning controllers 7a to 71 to the central unit 15 after a certain period of time has elapsed, the signals are raised one by one in the same way.
t2-t3) This control is repeated until the upper limit value is below the specified value.

法で電力需用を調節すると、負荷調節が有効に働く。In step 107, if the equipment is stopped and the calculated electric energy decreases and falls below the specified electric energy lower limit, the answer is NO and the process proceeds to step 10B, where the air conditioning controllers 7a to 71 of each air conditioner 3a to 31 Lower the set temperature by 1 degree. Next, the process proceeds to step 109 to check whether the set temperature matches the preset temperature before generating the demand control signal. If they match, the process proceeds to step 110 and stops lowering the set temperature. If there is a discrepancy, return to step 107 and repeat again.As described above, if many air conditioners with compressors are used in offices such as buildings, they account for a large portion of the electrical load, so If the above-described method is used to adjust the power demand when a situation in which the power load is exceeded occurs, the load adjustment will work effectively.

効果が得られる。Effects of the Invention As described above, according to the present invention, the electric energy of all equipment - white stripes is input and stored in the central device without using a demand controller or a power meter, and the equipment is operated using that value. When the amount of electricity exceeds a specified value, the demand control means issues a signal and shifts the set temperature by a fixed amount for each air conditioner, thereby controlling the indoor temperature during air conditioning operation. The effect is that demand control can be performed while minimizing the variation in the difference in set temperature.
