PROBLEM TO BE SOLVED: To provide an air-conditioning system, in which pairing or grouping between outdoor units connected to a double-circuit type indoor unit can be automatically conducted. SOLUTION: An outdoor side ECU 51 decides through a remote control line 4 that the address (2-1) of a refrigerant circuit B1b, which becomes the pair of a refrigerant circuit B1a connected to a first outdoor unit A1 can be detected or not and when the decision is Yes, the address (2) of a second outdoor unit A2, which becomes a pair of the first outdoor unit A1, is read and pairing with the second outdoor unit A2 is effected. Thereafter, the outdoor side ECU 51 decides that a first room temperature Tr1 and a second room temperature Tr2, detected by both refrigerant circuits B1a, B1b in the first indoor unit B1, are without a set temperature range or not and when the decision is Yes, the first and second outdoor units A1, A2 are operated simultaneously but when the decision is No, the first and second outdoor units A1, A2 are stopped simultaneously. |
