Particularly, in the related art, a mode of adjusting a wind guide door of an air conditioner or reducing the wind speed of the air conditioner is generally adopted, so that the air outlet of the air conditioner is prevented from blowing directly to a user. However, the above method has the disadvantage that the air supply comfort level of the air conditioner is not ideal, and the user experience is affected. In order to solve the problem, the present invention provides a method for controlling an air conditioner according to an inner loop temperature T in a case where the air conditioner needs to be operated in a target blowing mode (i.e., an intelligent comfort blowing mode) through step S100Inner ringAnd inner disc temperature TInner discAnd the frequency F of the compressor is controlled, so that the air supply comfort degree of the air conditioner is improved under the precondition that the refrigeration requirement or the dehumidification requirement of a user is ensured, and intelligent comfortable air supply is realized.

For example, the critical inner ring temperature threshold TInner ring threshold boundaryA preferred value of 22 deg.c.
It can be understood that, under the condition that the inner ring temperature is less than or equal to the critical inner ring temperature threshold, the inner ring temperature is lower, if the refrigerating air outlet temperature is controlled to be too low at the moment, cold air is blown directly to a user, the refrigerating effect is better at the moment, and the refrigerating effect is not needed to be considered too much, so that the frequency of the compressor is controlled to be reduced or maintained unchanged, and the air supply comfort degree of the air conditioner is improved. Under the condition that the inner ring temperature is greater than the critical inner ring temperature threshold value, the inner ring temperature is moderate or higher, if the refrigerating air outlet temperature is controlled to be too low at the moment, cold air is blown directly to a user, and if the refrigerating air outlet temperature is controlled to be too high, the refrigerating effect cannot be ensured, so that the frequency of the compressor is controlled to be reduced or increased or kept unchanged, and the air supply comfort degree of the air conditioner is improved on the premise that the refrigerating requirement or the dehumidifying requirement of the user is ensured.

It can be understood that, in the case where the inner ring temperature is less than or equal to the first inner ring temperature threshold and the inner disc temperature is less than the first inner disc temperature threshold, the indoor temperature is lower and the outlet air temperature is lower. Because the refrigeration effect is better at this moment, the refrigeration effect does not need to be considered too much, so the frequency of the compressor is controlled to be reduced, and the problem that cold air is blown directly to a user due to too low refrigeration air-out temperature is avoided.
