[0047] like Figure 1-Figure 4 As shown, the present invention provides an air conditioner control method for controlling an air conditioner, the air conditioner comprising a compressor and a liquid storage tank connected to an air intake port of the compressor, an air return module provided in the liquid storage tank, the air return module being provided with an air return port connected to the air intake port, the air return module being able to adjust the height position of the air return port by moving up and down, the air conditioner control method comprising:

[0048] S100, after the air conditioner enters the cooling mode, when the indoor temperature is greater than the cooling set temperature, the return air module is controlled to move up and down according to the indoor temperature and the cooling set temperature to adjust the height position of the return air port.

[0049] The cooling setting temperature is the indoor temperature that the user sets for the air conditioner in cooling mode, which is generally lower than the indoor temperature when cooling starts.

[0050] Among them, controlling the up and down movement of the air return module is to adjust the position of the air return module in the height direction of the liquid storage tank, including two adjustment methods. One is to adjust the position of the air return module upward, that is, to increase the position of the air return port; the other is to adjust the position of the air return module downward, that is, to lower the position of the air return port.

[0051] Among them, according to actual conditions, after the air conditioner enters the cooling mode, the indoor temperature can be periodically obtained, and the position of the return air module can be periodically adjusted according to the periodically obtained indoor temperature.

[0052] It can be understood that the air conditioner control method controls the up and down movement of the return air module through the indoor temperature and the refrigeration set temperature. In essence, it adjusts the height position of the return air port according to the indoor temperature and the refrigeration set temperature, and then adjusts the compressor return liquid amount, so that the position of the return air module can not only match the refrigeration load demand, but also avoid liquid hammer caused by excessive return liquid.

[0053] In some embodiments, S100, adjusting the height of the return air module according to the indoor temperature and the cooling set temperature includes:

[0054] S110, determining a first difference between the indoor temperature and the cooling set temperature.

[0055] When the indoor temperature is greater than the cooling setting temperature, the first difference = indoor temperature - cooling setting temperature.

[0056] The first difference actually reflects the load level of the air-conditioning compressor based on the current indoor temperature. The larger the first difference is, the greater the load of the compressor is, and the smaller the first difference is, the smaller the load of the compressor is.

[0057] S120, controlling the air return module to move up and down according to the first difference.

[0058] Among them, the position of the air return module represents the amount of liquid returned. The lower the position of the air return module is, the greater the amount of liquid returned is, and the higher the position of the air return module is, the lower the amount of liquid returned is.

[0059] Therefore, controlling the up and down movement of the air return module according to the first difference is essentially adjusting the return liquid amount of the compressor according to the load of the compressor.

[0060] In some embodiments, S120, controlling the air return module to move up and down according to the first difference includes:

[0061] S121, determining a difference range in which the first difference value is located, and controlling the air return module to move up and down according to the difference range corresponding to the first difference value.

[0062] Among them, a plurality of difference ranges (i.e., difference intervals) are pre-stored in the controller of the air conditioner. After determining the first difference, the corresponding difference range (difference interval) can be matched. After determining the difference range (difference interval) in which the first difference is located, the return air module can be controlled to move up and down according to the difference range (difference interval) in which the first difference is located. Since the larger the first difference is, the greater the compressor load represented, the greater the required return liquid volume, and the return air module needs to be lowered; the smaller the first difference is, the smaller the compressor load represented, the smaller the required return liquid volume, and the return air module needs to be raised.

[0063] S122: If the first difference is greater than the first threshold and less than or equal to the second threshold, move the air return module to a first height position.

[0064] S123: If the first difference is greater than the second threshold and less than or equal to the third threshold, move the air return module to a second height position.

[0065] S124: If the first difference is greater than the third threshold and less than or equal to the fourth threshold, move the air return module to a third height position.

[0066] Among them, the first threshold is smaller than the second threshold, the second threshold is smaller than the third threshold, the third threshold is smaller than the fourth threshold, the first height position is higher than the second height position, and the second height position is higher than the third height position, that is, a difference range (difference interval) corresponds to a height position, if multiple different first difference values ​​are in a difference range, then the multiple different first difference values ​​are still in the same height position.

[0067] In some embodiments, S120, controlling the air return module to move up and down according to the first difference includes:

[0068] The position of the air return module is controlled to decrease as the first difference increases, and to increase as the first difference decreases.

[0069] Among them, this embodiment can periodically obtain the indoor temperature and determine the first difference of the corresponding cycle, and then adaptively control the up and down movement of the return air module according to the periodically determined first difference. If the first difference determined in this cycle decreases compared with the previous cycle, the position of the return air module is appropriately lowered. If the first difference of this cycle increases compared with the previous cycle, the position of the return air module is appropriately raised.

[0070] In some embodiments, the air conditioner control method further includes:

[0071] S500, after the air conditioner enters the heating mode, when the indoor temperature is lower than the heating set temperature, the return air module is controlled to move up and down according to the indoor temperature and the heating set temperature.

[0072] The heating set temperature is the indoor temperature that the user sets for the air conditioner in heating mode, which is generally lower than the indoor temperature when heating starts.

[0073] Among them, in the heating mode, controlling the up and down movement of the air return module is also the same as the above-mentioned scheme for controlling the up and down movement of the air return module, that is, it includes two adjustment methods: adjusting upward or adjusting downward along the height direction of the liquid storage tank.

[0074] The air conditioner control method controls the up and down movement of the return air module by the indoor temperature and the heating set temperature. In essence, the position of the return air port is adjusted according to the indoor temperature and the heating set temperature, and then the return liquid amount of the compressor is adjusted, so that the position of the return air module can not only match the heating load demand, but also avoid liquid hammer caused by excessive return liquid.

[0075] In some embodiments, S500, controlling the air return module to move up and down according to the indoor temperature and the heating setting temperature includes:

[0076] S510, obtaining a second difference between the heating setting temperature and the indoor temperature.

[0077] When the indoor temperature is lower than the heating setting temperature, the second difference=the heating setting temperature-the indoor temperature.

[0078] The second difference actually reflects the load level of the air-conditioning compressor based on the current indoor temperature. The larger the second difference is, the greater the load of the compressor is, and the smaller the second difference is, the smaller the load of the compressor is.

[0079] S520, controlling the air return module to move up and down according to the second difference.

[0080] Among them, the position of the air return module represents the amount of liquid returned. The lower the position of the air return module is, the greater the amount of liquid returned is, and the higher the position of the air return module is, the lower the amount of liquid returned is.

[0081] Therefore, controlling the up and down movement of the air return module according to the second difference is essentially adjusting the return liquid amount of the compressor according to the load of the compressor.

[0082] In some embodiments, S520, controlling the air return module to move up and down according to the second difference includes:

[0083] S521, determining a temperature range in which the second difference value is located, and controlling the air return module to move up and down according to the temperature range corresponding to the second difference value.

[0084] Among them, a plurality of difference ranges (i.e., difference intervals) are pre-stored in the controller of the air conditioner. After determining the second difference, the corresponding difference range (difference interval) can be matched. After determining the difference range (difference interval) in which the second difference is located, the return air module can be controlled to move up and down according to the difference range (difference interval) in which the second difference is located. Since the larger the second difference, the greater the compressor load represented, the greater the required return liquid volume, and the return air module needs to be lowered; the smaller the second difference, the smaller the compressor load represented, the smaller the required return liquid volume, and the return air module needs to be raised.

[0085] S522: If the second difference is greater than the fifth threshold and less than or equal to the sixth threshold, move the air return module to a fourth height position.

[0086] S523: If the second difference is greater than the sixth threshold and less than or equal to the seventh threshold, move the air return module to a fifth height position.

[0087] S524: If the second difference is greater than the seventh threshold value and less than or equal to the eighth threshold value, move the air return module to a sixth height position.

[0088] The fourth height position is higher than the fifth height position, and the fifth height position is higher than the sixth height position.

[0089] Among them, the fifth threshold is smaller than the sixth threshold, the sixth threshold is smaller than the seventh threshold, the seventh threshold is smaller than the eighth threshold, the fourth height position is higher than the fifth height position, and the fifth height position is higher than the sixth height position, that is, a difference range (difference interval) corresponds to a height position, if multiple different second differences are in a difference range, then the multiple different second differences are still at the same height position.

[0090] In some embodiments, S520, controlling the air return module to move up and down according to the second difference includes:

[0091] The position of the air return module is controlled to decrease as the second difference increases, and to increase as the second difference decreases.

[0092] Among them, this embodiment can periodically obtain the indoor temperature and determine the second difference of the corresponding cycle, and then adaptively control the up and down movement of the return air module according to the periodically determined second difference. If the first difference determined in this cycle decreases relative to the previous cycle, the position of the return air module is appropriately lowered; if the second difference of this cycle increases relative to the previous cycle, the position of the return air module is appropriately raised.

[0093] In some embodiments, the present invention also provides an air conditioner control device 10, including an acquisition module 100, a judgment module 200 and a control module 300. The acquisition module 100 is used to acquire the indoor temperature after the air conditioner enters the cooling mode; the acquisition module 100 is also used to acquire the indoor temperature after the air conditioner enters the heating mode. The judgment module 200 is used to judge whether the indoor temperature is greater than the cooling set temperature after the air conditioner enters the cooling mode; the judgment module 200 is also used to judge whether the indoor temperature is less than the heating set temperature after the air conditioner enters the heating mode. The control module 300 is used to control the return air module to move up and down according to the indoor temperature and the cooling set temperature after the air conditioner enters the cooling mode and the indoor temperature is greater than the cooling set temperature; the control module 300 is also used to control the return air module to move up and down according to the indoor temperature and the heating set temperature after the air conditioner enters the heating mode and the indoor temperature is less than the heating set temperature.

[0094] The acquisition module 100 is also used to periodically acquire the indoor temperature after the air conditioner enters the cooling mode. The acquisition module 100 is also used to periodically acquire the indoor temperature after the air conditioner enters the heating mode.
