Abstract:
1. A central control system of air conditioners, comprising: a multi-type air conditioning system including a plurality of indoor units for air conditioning installed in rooms of a building and an outdoor unit for controlling circulation of refrigerant, said plurality of indoor units sharing the outdoor unit; a central control unit connected to the multi-type air conditioning system via a network, said central control unit performing central control of operations of the multi-type air conditioning system or performing monitoring of states thereof, said central control unit performing peak power control if a current power consumption of the multi-type air conditioning system, calculated based on operating states of the multi-type air conditioning system, exceeds a previously input reference management power value; and a signal converter connected between the multi-type air conditioning system and the central control unit, said signal converter performing mutual conversion of different protocol signals communicated between the multi-type air conditioning system and the central control unit, wherein the central control unit includes: a data transmitter/receiver for data transmission and reception to and from the multi-type air conditioning system via a network; a database for storing equipment information of power consumption and a pipe length of each of the indoor and outdoor units of the multi-type air conditioning system; a peak power processor for calculating a total power consumption of outdoor and indoor units in operation based on the power consumption of each of the outdoor and indoor units stored in the database; and an air conditioner controller for performing peak power control to change operating modes of the outdoor and indoor units according to a forcible operation algorithm if the total power consumption calculated by the peak power processor exceeds the reference management power value.
