Abstract
PURPOSE: To save the energy and obtain the safety by a method wherein the power source of an outdoor unit is automatically switched off after the end of predetermined operation when all indoor units are stopped their operations at the air conditioner, to which a plurality of the indoor units are connected.
CONSTITUTION: The larger one of either of temperature deviation signals VTA and VTB of respective indoor units 2A and 2B is outputted as the capacity controlling signal VC through a central processing unit 21 to a compressor controlling circuit 34. When the operating swtches 13A and 13B of the indoor units 2A and 2B are switched off under the condition as mentioned above, however operating signals VDA and VDB are not applied to a self-holding circuit 22, the central processing unit 21 holds a holding signal VH in the H level state to continue to supply the electricity to an outdoor controlling circuit 8, in which solenoid valves 6 are still being opened even under the condition that a compressor 3 and a fan 5 stand still. After the elapse of the predetermined time, a DC power circuit 20 is automatically off and after that all the power sources are off.
