ABSTRACT:
Disclosed are a central control system for multi-type air conditioners and an operating method thereof. In the central control system, multi-type air conditioners comprise a large number of indoor devices and a small number of outdoor devices, and a central controller is coupled to the multi-type air conditioners over a network. The central controller transmits a control graphic user interface (GUI) program provided therein to the remote control device so that an integrated control operation for respective air conditioners can be carried out. The central controller adjusts a transmission time of the control command signal received from the remote control device and transmits the control command signal to a corresponding air conditioner according to a result of the adjustment so that signal collision can be avoided. As the multi-type air conditioners installed within a building can be centrally controlled and efficiently managed, and control command signals from control devices coupled to the central controller over an internal/external network are transmitted to corresponding air conditioners, a control operation can be reliably performed.
