Abstract

PURPOSE: To save the energy and obtain the safety by a method wherein the power source is automatically off after the result of ORing of indoor loading signals, which are on-off, is in off state at the air conditioner, to which a plurality of the indoor units are connected.
CONSTITUTION: A compressor 3 is on-off controlled with the result of ORing of the indoor load signals VTA and VTB, which are on-off, as a compressor controlling signal VC by means of the central processing unit 21 of an outdoor controlling circuit 8. When the indoor load signal VTB of the room B is brought into off state after the cooling of the room A has already stopped, the compressor 3 and an outdoor fan 5 stand still, while a solenoid valve 6 is still held on. After the elapse of the predetermined time, a holding signal VH of the central pressing unit 21 goes H level to turn a relay 23 off and a DC power supply VCC reaches to zero. As a result, the self-holding state of the relay 23 is released and the solenoid valve 6 is turned off in order to completely finish the whole operation with respect to the outdoor unit and after that all the power source are off.
