1. A system for controlling multiple air conditioners, the system comprising:
- a demand control unit configured to calculate an estimated power amount used by the multiple air conditioners based on an amount of power consumed by the multiple air conditioners during a predetermined time period, and to forcibly control an operation of one or more air conditioners based on a size of the estimated power amount;
one or more individual watt-hour meters, each being connected with respective air conditioners and configured to measure the power consumed by each of the one or more air conditioners; and
an overall watt-hour meter configured to measure the amount of power consumed by the entire system,wherein the demand control unit is connected to the multiple air conditioners and communicates with the multiple air conditioners using a serial data communication protocol.
