AIR CONDITIONING DEVICE

In an air conditioner, a power line (L), a signal line (S), and a common line (N) are connected to one another between an outdoor unit and an indoor unit. The indoor unit includes a relay (K2R) that is switched by an indoor control circuit (23) between an on state in which the relay (K2R) connects t...

Zusammenfassung:In an air conditioner, a power line (L), a signal line (S), and a common line (N) are connected to one another between an outdoor unit and an indoor unit. The indoor unit includes a relay (K2R) that is switched by an indoor control circuit (23) between an on state in which the relay (K2R) connects the signal line (S) and the power line (L) to each other and an off state in which the relay (K2R) disconnects the signal line (S) and the power line (L) from each other. The outdoor unit includes a relay (K13R) that is switched by an outdoor control circuit (13) between an on state in which the relay (K13R) connects the outdoor control circuit (13) to an AC power supply (40) and an off state in which the relay (K13R) connects the outdoor control circuit (13) to the signal line (S). The relay (K2R) is switched to the on state with the relay (K13R) being in the off state. When the outdoor control circuit (13) is started, the relay (K13R) is switched to the on state, and then the relay (K2R) is switched to the off state, thereby starting the outdoor unit.
