Abstract
A central control system and method is provided for controlling multiple air conditioners that include an outdoor device and a plurality of indoor devices. A central controller is connected through a dedicated line based on an air conditioner communication protocol to control the multiple air conditioners. The central controller is serially connected to a protocol converter for carrying out an Ethernet communication protocol conversion and an air conditioner communication protocol conversion. The central controller allows for remote control of the multiple air conditioners through an external Internet network based on the Ethernet communication protocol. Accordingly, data of different communication protocols are smoothly transmitted and received, and a stable control operation can be performed.
