In a multiple type air conditioner system which includes a plurality of outdoor units and a plurality of indoor units, the plurality of outdoor units are connected with the plurality of indoor units through a communication line, address setting is attained by generating a random address from each of all the indoor units under a command of one of the outdoor units and generating a dummy address from each outdoor unit on the basis of the random address, by obtaining a correlative relationship between the outdoor and indoor units on the basis of a variation of a physical quantity of the outdoor unit connected to the indoor unit actually operated based on the dummy address, and by updating the addresses of all the outdoor and indoor units on the basis of the correlative relationships between all the outdoor and indoor units obtained through the step.
An air conditioner system comprising a plurality of outdoor units each having a compressor, an outdoor heat exchanger and a 4-way valve and a plurality of indoor units having an expansion means and an indoor heat exchanger, said plurality of outdoor units are serially connected to said plurality of indoor units through a communication line, each of said outdoor units has an outdoor controller, each of said indoor units has an indoor controller, said outdoor controller includes communication means, outdoor control means for performing transmission and reception of a message to and from the other outdoor and indoor units through said communication means, random value generation means for generating a random address under a command of said outdoor control means, and address control means for storing therein said random address, said outdoor controller includes second communication means, indoor control means for performing transmission and reception of a second message to and from the other outdoor units through said communication means, second random value generation means for generating second random address under a command of said indoor control means, and second address control means for storing therein said second random address.
An address setting method for an air conditioner system comprising a plurality of outdoor units each having outdoor control means and a compressor and a plurality of indoor units each having indoor control means and physical quantity detection means, said plurality of outdoor units being serially connected to said plurality of indoor units through a communication line, said method comprising the steps of:
