Referring to fig. 2, fig. 2 is a flowchart illustrating a control method of the air conditioning system 100 according to a first embodiment of the present invention, and the control method of the air conditioning system 100 according to the first embodiment of the present invention is provided.
In the first embodiment, the control method of the air conditioning system 100 includes the steps of:
step S10: when the air conditioning system 100 works, the air outlet speed of the air filter 1 and the air outlet speed of the heat exchanger 3 are acquired in real time.
It should be understood that the execution subject of the present embodiment is the control device of the air conditioning system, wherein the control device of the air conditioning system may be an electronic device such as a personal computer or a server.
It should be noted that, when the air conditioning system 100 is operated, the blower 2 is started, and when the blower 2 rotates, air is sucked from the outside, and the air passes through the air filter 1, then reaches the impeller of the blower 2, and finally is the heat exchanger 3. Air filter 1 filters the air earlier, and air filter 1's filter core can be blockked up gradually in long-time use, consequently can judge the jam degree through air filter 1's air-out speed's change. Similarly, the heat exchanger 3 may be gradually blocked in a long-term use process, and the degree of blocking is also determined by the change of the air outlet speed of the heat exchanger 3.
Step S20: and calculating a first target difference value between the acquired air outlet speed of the air filter and a preset air outlet speed of the air filter.
It should be noted that the air outlet speed of the air filter 1 in a normal state, that is, in a case where no blockage occurs, is the preset air outlet speed of the air filter.
Step S30: and when the first target difference value exceeds a first preset threshold value, controlling the prompting device to send a prompt to prompt the replacement of the air filter.
It should be noted that the first preset threshold is a maximum value of a difference between the real-time air outlet speed of the air filter and the preset air outlet speed of the air filter, and once the value is greater than the maximum value, it is determined that the blockage occurs, and then the prompting device prompts to prompt the user to take measures.
Step S40: and calculating a second target difference value between the acquired air outlet speed of the heat exchanger and the preset air outlet speed of the heat exchanger.
It should be noted that the air outlet speed of the heat exchanger 3 in a normal state, that is, in a case where no blockage occurs, is the preset air outlet speed of the heat exchanger.
Step S50: and when the second target difference value exceeds a second preset threshold value, controlling the prompting device to give a prompt for prompting to clean the heat exchanger.
It should be noted that the second preset threshold is a maximum value of a difference between the real-time air outlet speed of the heat exchanger and the preset air outlet speed of the heat exchanger, and once the difference is greater than the maximum value, it is determined that the blockage occurs, and then the prompting device prompts to prompt the user to take measures.

It should be noted that, in general, the operating range of the blower 2 is three, i.e., strong, medium, and weak, but is not limited thereto. The rotating speeds of the impellers of the blower 2 are different according to different gears, and the air outlet speed of the whole air conditioning system 100 is also different.
Step S102: and adjusting the first preset threshold and the second preset threshold according to the current working gear of the air blower 2.
It should be noted that: when the blower 2 is in a strong gear, the first preset threshold value is 1m/s, and the second preset threshold value is 0.9 m/s; when the blower 2 is in the middle gear, the first preset threshold value is 0.8m/s, and the second preset threshold value is 0.7 m/s; when the blower 2 is in a weak gear, the first preset threshold value is 0.6m/s, and the second preset threshold value is 0.5 m/s. When the blower 2 is in a strong gear, the preset air outlet speed of the air filter 1 is 6m/s, and the preset air outlet speed of the heat exchanger 3 is 5.5 m/s; when the blower 2 is in the middle gear, the preset air outlet speed of the air filter 1 is 4m/s, and the preset air outlet speed of the heat exchanger 3 is 3 m/s; when the blower 2 is in a weak gear, the preset air outlet speed of the air filter 1 is 2m/s, and the preset air outlet speed of the heat exchanger 3 is 1.5m/s.
A third embodiment of the control method of the air conditioning system of the present invention is proposed based on the first embodiment shown in fig. 2 described above.
In the third embodiment, the step S50 includes:
step S501: and when the second target difference value exceeds a second preset threshold value, controlling the spray head 4 to be opened so as to flush the heat exchanger 3.

The flushing time is five seconds each time, and the flushing is automatically stopped after the time.
In a third embodiment, when the second target difference exceeds a second preset threshold, the spray head 4 is controlled to be opened for flushing the heat exchanger 3. The user does not need to go to a maintenance shop specially to clean, and the time, labor and money are wasted.

Step S104: and calculating the air filter wind speed difference between the air outlet speed of the air filter at each position and the preset air outlet speed of the corresponding air filter.
It can be understood that the air outlet speed at each position is different, but the preset air outlet speed of the air filter is the same in the same gear, so that the air speed difference of the air filters can be increased in the same gear.
Step S105: and sequencing the air filter air speed difference values, and taking the maximum air filter air speed difference value as the first target difference value according to a sequencing result.
It will be appreciated that the magnitude of the air filter wind speed difference is representative of the degree of blockage, and the largest of the air filter wind speed differences is taken as the first target difference that is ultimately uniquely determined.
