The purpose of S100 is to improve the comfort level of the air supply of the air conditioner. Specifically, 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 to avoid the direct blowing of the air out of the air conditioner. However, the disadvantage of the above method is that the comfort level of the air supply of the air conditioner is not ideal enough, which affects the user experience. In order to solve the problem, the present invention provides a method for controlling an air conditioner according to an inner ring temperature T in a case where the air conditioner needs to be operated in a target air supply mode (i.e., intelligent comfort air supply mode) through step S100 Inner ring And inner disk temperature T Inner disc The compressor frequency F is controlled, so that the air supply comfort level of the air conditioner is improved and intelligent comfortable air supply is realized under the precondition that the refrigerating requirement or the dehumidifying requirement of a user is guaranteed.

s110, according to the inner ring temperature T Inner ring And an inner ring temperature threshold T Inner ring threshold Is a comparison result of the inner disk temperature T Inner disc And the inner disk temperature threshold T Inner disk threshold The compressor frequency F is controlled.
It can be understood that the control accuracy of the operation frequency of the compressor can be improved by controlling the frequency of the compressor according to the comparison result of the inner ring temperature and the inner ring temperature threshold value and the comparison result of the inner disc temperature and the inner disc temperature threshold value, so that the control accuracy of the air outlet temperature of the air conditioner and the air supply comfort level of the air conditioner can be improved, and intelligent and comfortable air supply is realized.
In one example of the present invention, S100 is based on an inner ring temperature T of the air conditioner Inner ring And inner disk temperature T Inner disc Controlling a compressor frequency F of an air conditioner, comprising:

It can be understood that through dividing different inner ring temperature intervals, optimize the inner tray temperature and control the air-out temperature, can guarantee under the user effect demand, realize intelligent comfortable air supply.

s141, inner ring temperature T Inner ring Less than or equal to critical inner loop temperature threshold T Inner annular threshold boundary In the case of (1) according to the inner disk temperature T Inner disc Controlling the compressor frequency F to be reduced or maintained unchanged;
s142, inner ring temperature T Inner ring Greater than critical inner loop temperature threshold T Inner annular threshold boundary In the case of (1) according to the inner disk temperature T Inner disc The compressor frequency F is controlled to decrease or increase or remain unchanged. For example, the critical inner loop temperature threshold T Inner annular threshold boundary The preferred value of (2) is 22 ℃.
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 value, the inner ring temperature is lower, if the control refrigeration air outlet temperature is too low at this time, the direct blowing of cold air can be caused, and the refrigeration effect is better at this time, and the refrigeration effect is not needed to be considered too much, so the control compressor frequency is reduced or kept unchanged, and the air supply comfort degree of the air conditioner is improved. Under the condition that the inner ring temperature is larger than the critical inner ring temperature threshold value, the inner ring temperature is moderate or higher, if the control refrigeration air outlet temperature is too low at this time, cold air directly blows users, and if the control air outlet temperature is too high, the refrigeration effect cannot be ensured, so the control compressor frequency is reduced or increased or kept unchanged, and the air supply comfort degree of the air conditioner is improved under the premise of ensuring the refrigeration requirement or the dehumidification requirement of the users.

For example, the first inner ring temperature threshold T Inner ring threshold 1 Is preferably 22 ℃; the first inner disk temperature threshold T Inner disk threshold 1 Is preferably 12 ℃.
It is 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 disk temperature is less than the first inner disk temperature threshold, the indoor temperature is lower and the outlet air temperature is lower. Because the refrigerating effect is better at this moment, need not too much consideration refrigerating effect, so control compressor frequency reduces to avoid refrigerating the problem that the low temperature of air-out leads to cold wind to blow user directly.
In one example of the present invention, S100 is based on an inner ring temperature T of the air conditioner Inner ring And inner disk temperature T Inner disc Controlling a compressor frequency F of an air conditioner, comprising:
