The storage unit of valve stores the electronic expansion valve position signal and init state information;The electric expansion valve executes storage
It sends to preserve afterwards and completes feedback signal to the air-conditioner controller, then control the electric expansion valve normal powering down;
Or the storage unit of the air-conditioner controller stores the electronic expansion valve position signal and init state information, then
Control the electric expansion valve normal powering down.
17. the control method of the air-conditioning system according to any one of claim 13-16, which is characterized in that in the sky
When controller being adjusted to start the control electric expansion valve power down program, the control method includes:
The air-conditioner controller or electric control part send initialization control signal electron expansion valve, control electric expansion valve into
Row initialization, after the completion of initialization, then controls the storage unit of the air-conditioner controller or the storage unit of electric control part
The status information and location information come to electric expansion valve feedback stores.
