Abstract:

A multi-room air conditioner where, in selecting one operation mode among operation modes with different low noise levels, requirements from individual rooms are adjusted. A heat source side control section (20) of the air conditioner (1) has an operation mode allocation section (22), an operation mode setting section (23), a heat source unit (2), and utilization units (3). The heat source unit (2) can be switched to multiple operation modes having different low noise levels. The operation allocation section (22) allocates the one operation mode to each of the utilization unit (3) being operated. The operation mode setting section (23) sets the heat source unit (2) to the one operation mode of the operation modes based on the operation mode allocated by the operation mode allocation section (22) to each of the utilization unit (3) being operated. When a predetermined operation mode is allocated to all the utilization units (3) being operated, the operation mode setting section (23) sets the heat source unit (2) to the predetermined operation mode.
