Abstract:
1. A control apparatus for a multi-room air conditioner having a heat source unit being configured to be switched among a plurality of operating modes having different noise-reduction levels, and a plurality of conditioning units being connected to the heat source unit via a refrigerant communication tube and distributed among a plurality of rooms, the control apparatus for the multi-room air conditioner comprising: an operating mode allocator being configured to allocate one operating mode from among the plurality of operating modes to each of the operating conditioning units of the plurality of conditioning units; and an operating mode setter being configured to set the heat source unit to one operating mode from among the plurality of operating modes on the basis of the operating modes allocated by the operating mode allocator to each of the operating conditioning units, the plurality of operating modes including a first operating mode and a second operating mode in which the noise reduction level is higher than in the first operating mode, under a first condition in which a specific operating mode from among the plurality of operating modes is allocated to all of the operating conditioning units, the operating mode setter setting the heat source unit to the specific operating mode, and under a second condition in which the second operating mode is allocated to at least one of the operating conditioning units, and the performance required in the operating conditioning units is less than a specific level, the operating mode setter setting the heat source unit to an operating mode in which the noise-reduction level is higher than in the first operating mode.
