Abstract
A central control system includes a plurality of air conditioners and a central control unit connected to the air conditioners over a network. The air conditioners are installed in rooms of a building to provide air conditioning in the rooms. The central control unit receives a control command for monitoring and controlling each of the air conditioners, and adjusts an operating schedule of each of the air conditioners to limit total peak power consumption of the air conditioners in operation below a reference power value. The central control unit controls the operation of each of the air conditioners based on the adjusted operating schedule. When the total peak power consumption exceeds the reference power value, the central control unit prevents the entire air conditioning system from shutting down, which improves stability of the air conditioning system and decreases electricity costs for air conditioning.
