PROBLEM TO BE SOLVED: To provide an air-conditioning system, enabling centralized control of a plurality of heat accumulation units installed respectively in a plurality of groups of a multizone air-conditioning system by use of a single controller. SOLUTION: The air-conditioning system group G1 comprises an outdoor unit A1, a heat accumulation unit B1 and at least three indoor units (D11-D13, and others). Units of each group (G1-G3) are respectively connected to neutral two-core communication lines T1-T3 and further connected to a system controller S1, for effecting centralized administration control of the whole air conditioning system by a communication line T0. The heat accumulation units (B1-B3) of the respective groups (G1-G3) are connected to the controller 10, by a neutral two-core communication line P10 so as to effect centralized administration control of the respective heat accumulation units (B1-B3). |
