PURPOSE: To effectively use communication lines by effectively transferring data among air-conditioners, by a method wherein only the data relevant to full-operating condition, specific operating condition, and state change operating condition of each air- conditioner are selectively collected to a controller for air-conditioning system.
CONSTITUTION: Each apparatus and a local centralized-controller 14 in an airconditioning block 'B' 12, are joined to a transmitting way 13 in the airconditioning block, like a bus in a microcomputer, and the local centralized-controller 14 does centralized control and state-monitoring. Data in the air-conditioning block 'B' 12 are controlled by a transmission converter 15 for the air-conditioning block, which is joined to both the transmitting way 13 in the air-conditioning block and a transmitting way 7 outside the air-conditioning block. After that, the data in each of the air-conditioning blocks are respectively transmitted and converted by each of the transmission converters, and are transmitted to a controller 17 for all of the air- conditioners through a transmission controller 16, and are controlled. The control data from the controller 17 are transmitted to each of the local centralized-controllers through the transmission controller 16, and control all of the apparatuses in each of airconditioning blocks.
