It should be noted that, under the condition that the content of particulate matters in the air is large, dust and impurities in the air are easy to adhere to fins to cause dirt blockage, so that the heat exchange effect of the heat exchanger is poor, and the defrosting is frequently performed, so that the defrosting control condition is corrected, the defrosting period is prolonged, and the comfort of a user is improved.
In order to correct the defrosting control condition of the air conditioning unit according to the content of the particulate matter in the target environment, optionally, in the control method of the air conditioner provided in the embodiment of the present application, in a case that the content of the particulate matter in the target environment is greater than a preset content, correcting the defrosting control condition of the air conditioning unit includes: judging the level of the content of the particulate matters in the target environment; and correcting the defrosting control condition of the air conditioning unit on the original defrosting control condition according to the grade of the content of the particulate matters in the target environment, wherein the original defrosting control condition is a preset temperature value for controlling the air conditioning unit to carry out defrosting.
It should be noted that the larger the air particulate content is, the larger the degree of reducing the heat exchange effect of the heat exchanger is, the greater the defrosting control condition needs to be corrected on the original defrosting control condition, the degree of influence of different air particulate contents on the heat exchange effect of the heat exchanger can be tested through experiments to set the air particulate content grade range, a plurality of grades are set, the grade is automatically judged according to the detected air particulate content, and the defrosting control condition of the air conditioning unit is corrected according to the grade.

and controlling the air conditioning unit to defrost when the temperature detected by the air conditioning defrosting bulb meets the defrosting control condition of the air conditioning unit.
4. The method of claim 1, wherein modifying the defrosting control condition of the air conditioning unit over the original defrosting control condition according to the grade to which the particulate matter content in the target environment belongs comprises:
setting a correction value for each grade of particulate matter content grade;
determining defrosting control conditions corresponding to the content grade of the particulate matters at each grade based on the original defrosting control conditions and the corrected values;
judging the level of the content of the particulate matters in the target environment;
and taking the defrosting control condition corresponding to the particulate matter content grade to which the particulate matter content in the target environment belongs as the corrected defrosting control condition.
5. The method according to any one of claims 1 to 4, further comprising:
and when the content of the particulate matters in the target environment is less than or equal to the preset content, or when the air conditioning unit is shut down, restoring the defrosting control condition of the air conditioning unit to an original defrosting control condition, wherein the original defrosting control condition is a preset temperature value for controlling the air conditioning unit to execute defrosting.
6. A control device of an air conditioner, characterized by comprising:
the first detection unit is used for detecting the content of particulate matters in a target environment, wherein the target environment is the environment where a heat exchanger of an air conditioning unit is located;
the correcting unit is used for correcting the defrosting control condition of the air conditioning unit under the condition that the content of the particulate matters in the target environment is larger than a preset content, wherein the defrosting control condition of the air conditioning unit is a temperature condition for controlling the air conditioning unit to perform defrosting;
wherein the correction unit includes: the judgment module is used for judging the level of the content of the particulate matters in the target environment; a correcting module, configured to correct a defrosting control condition of the air conditioning unit on an original defrosting control condition according to a grade to which a content of particulate matter in the target environment belongs, where the original defrosting control condition is a preset temperature value for controlling the air conditioning unit to perform defrosting, and the correcting the defrosting control condition of the air conditioning unit includes: the defrosting temperature is controlled to be reduced along with the increase of the particulate content grade to which the particulate content in the target environment belongs.
7. An air conditioner characterized by being configured to execute the control method of the air conditioner of any one of claims 1 to 5.
8. A storage medium characterized by comprising a stored program, wherein the program executes the control method of an air conditioner according to any one of claims 1 to 5.
9. A processor, characterized in that the processor is configured to execute a program, wherein the program executes the control method of the air conditioner according to any one of claims 1 to 5.
