Light current input)；Optionally, the energy stored in the electrolytic capacitor of filter circuit is discharged by compressor load；It is optional
Ground, the first main control MCU 101 may also turn off useless external equipment (such as electric expansion valve, four-way valve, heat tape etc.), and
Into low standby power loss mode (i.e. suspend mode)；(C), when one drags any air conditioner indoor unit of more air-conditionings to receive user's input
Whens the remote signal etc. that button operation or user are inputted by remote controler, the 2nd MCU 115 of air conditioner indoor unit exits low immediately
Stand-by power consumption pattern switching is normal mode of operation, and exits suspend mode to the transmission of the first main control MCU 101 of air-conditioner outdoor unit and refer to
It enables, to notify air-conditioner outdoor unit preparation to exit to stand-by power consumption mode.
In conclusion provided by the embodiments of the present application one drags more air-conditionings, by adding buck converter in air-conditioner outdoor unit
BUCK circuit and power switch circuit, when the first master control micro-control unit MCU of air-conditioner outdoor unit receives air conditioner indoor unit
After the dormancy instruction of transmission, the first main control MCU instruction driving MCU control power switch circuit is in an off state, and is controlled
The output of BUCK circuit is zero；As it can be seen that being disconnected all strong and weak electricities input of driving circuit section, the standby function of driving circuit section
It consumes substantially zeroed；Further, the first main control MCU closes useless external equipment, waits for reduce main control circuit part
Machine power consumption, to reduce standby power consumption of air-conditioner outdoor unit；Further, pass through bus communication, phase between air-conditioning indoor and outdoor machine
Than greatly reducing air-conditioning indoor and outdoor machine communication power consumption in existing communication modes (such as electric current loop communicates)；Further, air-conditioning
Indoor unit reduces the standby function of air conditioner indoor unit by using low standby power loss power supply and with the functional chip of suspend mode
Consumption；Therefore, provided by the embodiments of the present application one drag the outer machine stand-by power consumption of more air-conditionings very low.
