Abstract (en)
An air conditioning system (100) includes a refrigerant cycle (RC), a power feed unit (40), a controller (60), and a determining unit (90). The refrigerant cycle (RC) includes an outdoor unit (10) and a plurality of indoor units (30). The outdoor unit (10) includes a compressor (11). In a case where a power source for at least one indoor unit of the plurality of indoor units (30) is interrupted, the power feed unit (40) feeds power from an auxiliary power source to the at least one indoor unit. The controller (60) controls at least the compressor (11). In the case where the power source for the at least one indoor unit of the plurality of indoor units (10) is interrupted, the determining unit (90) makes one of a determination to stop the compressor (11) and a determination to cause the compressor (11) to continue operating. The determining unit (90) transmits to the controller (60) an instruction corresponding to the determination that has been made.
