Fig. 3 is a block diagram of an embodiment of an air conditioning control apparatus according to the present invention. The device is particularly suitable for use in fixed frequency air conditioners.
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 air conditioner has a large air conditioner small room. 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.

If the temperature difference is less than or equal to a first preset temperature value, reducing the air inlet area of the air inlet to a first preset percentage of the total area of the air inlet; and after the air inlet area of the air inlet is reduced to a first preset percentage of the total area of the air inlet, controlling the air inlet area of the air inlet and/or the rotating speed of the indoor fan according to the cooling rate of the room in which the air inlet is located. If the cooling rate is less than or equal to a second preset threshold, the air inlet area of the air inlet is reduced to a second preset percentage of the total area of the air inlet; if the cooling rate is greater than a second preset threshold value, the air inlet area of the air inlet and/or the rotating speed of the indoor fan are/is further adjusted according to whether the temperature difference between the indoor environment temperature and the set temperature is smaller than or equal to a third preset temperature value. That is, after the air inlet area of the air inlet is reduced to the first preset percentage of the total area of the air inlet, the air inlet area of the air inlet and/or the rotating speed of the indoor fan are/is adjusted according to the cooling rate of the room.

Wherein, whether the temperature difference according to indoor ambient temperature and settlement temperature be less than or equal to the fifth preset temperature value control indoor fan rotational speed includes: if the temperature difference is less than or equal to a fifth preset temperature value, controlling the rotating speed of the indoor fan to operate according to a preset gear; and after the rotating speed of the indoor fan is controlled to operate according to a preset gear, if the temperature difference is less than or equal to a sixth preset temperature value, the compressor is controlled to stop.

If the cooling rate of the room is smaller than the first preset threshold, it indicates that the air conditioning cooling capacity is normally matched with the room, and at this time, the control unit 120 adjusts the air inlet area of the air inlet and/or the indoor fan rotating speed according to the temperature difference between the indoor environment temperature and the set temperature and/or the cooling rate of the room.
Specifically, if the temperature difference is less than or equal to a second preset temperature value, the air inlet area of the air inlet is reduced to a first preset percentage of the total area of the air inlet; and after the air inlet area of the air inlet is reduced to a first preset percentage of the total area of the air inlet, controlling the air inlet area of the air inlet according to the cooling rate of the room in which the air inlet is positioned.
