When the Current Temperatures of described coil pipe is more than described second preset temperature, reduce the aperture of described electric expansion valve.
The control method of air-conditioner the most according to claim 7, it is characterised in that the described electric expansion valve of described reduction
The step of aperture, specifically includes:
The aperture of described electric expansion valve is reduced, until the Current Temperatures of described coil pipe is first pre-more than described according to predetermined speed
If temperature and less than or equal to the second preset temperature time till.
9. according to the control method of the air-conditioner according to any one of claim 6 to 8, it is characterised in that increase described electronics
The step of the aperture of expansion valve, specifically includes:
The aperture of described electric expansion valve is increased to maximum.
10. according to the control method of the air-conditioner according to any one of claim 6 to 8, it is characterised in that also include:
When described electric expansion valve reaches the second Preset Time with the time of the aperture continuous service after increasing, determine described dish
Whether the Current Temperatures of pipe is less than or equal to described first preset temperature；
If the Current Temperatures of described coil pipe is less than or equal to described first preset temperature, then control described air-conditioner out of service,
And point out air-conditioner described in user to break down；
Wherein, described second Preset Time is more than described first Preset Time.
