and b1, if no regulating mechanism matched with the outdoor temperature value, the exhaust port temperature value and the exhaust port temperature change rate exists, keeping the current operation state.
And if no regulating mechanism matched with the outdoor temperature value, the exhaust port temperature value and the exhaust port temperature change rate exists, the air conditioner keeps the current running state. It can be understood that, when the outdoor temperature is in the preset high temperature interval and the preset low temperature interval, a certain influence is caused on the working state of the high temperature sterilization mode of the air conditioner, and when the outdoor temperature value is in the preset high temperature interval and the preset low temperature interval, the influence of the outdoor temperature value on the working state of the high temperature sterilization mode of the air conditioner is limited, the interval is considered as a normal working interval, and the adjustment mechanism is not used for adjusting various parameters of the air conditioner but is defaulted to operate in the current state.
In this embodiment, when there is no adjusting mechanism matching with the outdoor temperature value, the exhaust port temperature value and the exhaust port temperature change rate, the air conditioner is kept in the current state to operate, and the air conditioner can normally operate without parameter adjustment by setting a temperature interval, so that excessive adjustment of the air conditioner is avoided.
