As shown in fig. 3, the air conditioning control apparatus 100 includes: a detection unit 110 and a control unit 120.
The detecting unit 110 is configured to detect whether a cooling rate of a room where the air conditioner is located is greater than or equal to a first preset threshold when the air conditioner is in a cooling operation.
Specifically, when the air conditioner operates in a cooling mode, the detection unit 110 detects whether the cooling rate of the room where the air conditioner is located is greater than or equal to a first preset threshold value, so as to determine whether the cooling capacity of the air conditioner is matched with the area of the room where the air conditioner is located according to the cooling rate, that is, whether the cooling rate of the room where the air conditioner is located is greater than or equal to the first preset threshold value is detected, and if the cooling rate is greater than or equal to the first preset threshold value, it is indicated that the cooling capacity of the air conditioner is not matched with the area of the room where the air conditioner is located, and the. For example, it is detected whether the cooling rate of the room is greater than or equal to a. The cooling rate is the reduction value of the indoor environment temperature of the room in unit time.
The control unit 120 is configured to, if the cooling rate is greater than or equal to the first preset threshold, control reduction of an air inlet area of the air inlet and/or reduction of a rotating speed of the indoor fan according to a temperature difference between the indoor environment temperature and the set temperature and/or the cooling rate of the room where the indoor environment temperature is located, so as to slow down a cooling speed; if the cooling rate is smaller than the first preset threshold, adjusting the air inlet area of the air inlet and/or the rotating speed of the indoor fan according to the temperature difference between the indoor environment temperature and the set temperature and/or the cooling rate of the room where the air inlet is located.
If the cooling rate of the room is greater than or equal to the first preset threshold, which indicates that the air conditioner has a large air-conditioning small room, the cooling speed should be slowed down in time, that is, the control unit 120 controls the air inlet area of the air inlet to be reduced and/or the rotating speed of the indoor fan to be reduced according to the temperature difference between the indoor environment temperature and the set temperature, so as to slow down the cooling speed.
