[0036] Combination Figure 2 As shown, the embodiment of the present disclosure provides a method for controlling an air conditioner, comprising:

[0037] S201, the air conditioner defrosts every preset period according to the thickness of frost on the outdoor unit δ i Adjust the defrost frequency of the compressor, the ratio of the compressor current to the total current protective shutdown current, and the duration of a single defrost.

[0038] S202, in δ i When the preset conditions are met, the air conditioner adjusts the gear of the indoor electric heating according to the temperature difference of the indoor temperature drop during the defrosting period.

[0039] By adopting the method for controlling the air conditioner provided by the embodiment of the present disclosure, the defrosting frequency of the compressor, the proportion of the compressor current to the total current protective shutdown current, and the single defrosting time can be accurately adjusted according to the frost thickness of the outdoor unit in each preset cycle, and the gear of the indoor electric heating can be accurately adjusted according to the temperature difference of the indoor temperature drop during the defrosting period.

[0040] Optionally, δ i Satisfy the preset conditions, including: i Reach the preset thickness threshold. Specifically, the value of the preset thickness threshold is 0. The value of the preset thickness threshold can be adjusted and set according to the properties of the air conditioner, which are not listed here one by one. In this way, the gear of the indoor electric heating can be accurately adjusted in time according to the temperature difference of the indoor temperature drop during the defrosting period after defrosting to a certain extent. Accurately control the defrosting process without blindly increasing or shortening the defrosting time, which is conducive to reducing room temperature fluctuations when the air conditioner outdoor unit is defrosted, saving energy and electricity, and avoiding malfunctions caused by icing of the outdoor unit.

[0041] Optionally, the air conditioner is configured according to the frost thickness δ of the outdoor unit. i Adjust the defrosting frequency of the compressor, the ratio of the compressor current to the total current protective shutdown current, and the duration of a single defrost, including: the frost thickness δ on the outdoor unit i In the case of the first preset thickness interval (δ0, δ1), the air conditioner adjusts the defrosting frequency of the compressor to the first preset defrosting frequency P1, the ratio of the compressor current to the total current protective shutdown current is A, and the single defrosting duration is the first preset duration t1. i When in the second preset thickness interval (δ1, +∞), the air conditioner adjusts the defrost frequency of the compressor to the second preset defrost frequency P2, the ratio of the compressor current to the total current protective shutdown current is B, and the single defrost duration is the second preset duration t2. Among them, the first preset thickness interval is lower than the second preset thickness interval, P1<P2, A<B, t1<t2. Specifically, the value range of δ0 is [3mm, 5mm]. The value of δ1 can be 8mm. The value of A can be 56%. The value of B can be 85%. More specifically, the value of δ0 can be 3mm or 5mm. The values ​​of δ0, δ1, A, and B can be adjusted and set according to the properties of the air conditioner, and they are not listed here one by one.

[0045] S303, in δ i When in the second preset thickness interval (δ1, +∞), the air conditioner adjusts the defrost frequency of the compressor to the second preset defrost frequency P2, the ratio of the compressor current to the total current protective shutdown current is B, and the single defrost duration is the second preset duration t2.

[0046] S304, in δ i When the air conditioner is in the third preset thickness interval (0, δ0), the defrost frequency of the air conditioner compressor is adjusted to the minimum preset defrost frequency P m , the single defrost duration is the third preset duration t3.

[0047] S305, in δ i When the defrost frequency is 0, the air conditioner adjusts the compressor defrost frequency to the minimum preset defrost frequency P m , the single defrost duration is the third preset duration t4.

[0048] S306, in δ i When the preset conditions are met, the air conditioner adjusts the gear of the indoor electric heating according to the temperature difference of the indoor temperature drop during the defrosting period.

[0049] The first preset thickness interval is lower than the second preset thickness interval, the third preset thickness interval is lower than the first preset thickness interval, P m <P1<P2, A<B, t4<t3<t1<t2.

[0050] Using the method for controlling an air conditioner provided by the embodiment of the present disclosure, δ iThe larger the value, the higher the defrost frequency of the compressor, the greater the proportion of the compressor current to the total current protective shutdown current, and the longer the single defrost duration. In each preset cycle, it is helpful to accurately adjust the defrost frequency of the compressor, the proportion of the compressor current to the total current protective shutdown current, and the single defrost duration according to the frost thickness of the outdoor unit, and accurately adjust the gear of the indoor electric heating according to the temperature difference of the indoor temperature drop during the defrost period. Accurately control the defrost process and do not blindly increase or shorten the defrost time, which is helpful to reduce room temperature fluctuations when the air conditioner outdoor unit is defrosted, save energy and electricity, and avoid failures caused by icing of the outdoor unit.

[0051] Optionally, P m =α*(CC / S). α is a dimensionless coefficient without actual numerical value, CC is the rated cooling capacity of the air conditioner, and S is the displacement of the compressor. The value of t4 can be 150s. Specifically, the value of CC can be 7200W, and the value of S can be 17.2cm 3 In this way, it is beneficial to i When it is 0, the defrost frequency and single defrost duration of the compressor can be adjusted more accurately according to the frost thickness of the outdoor unit.

[0052] Optionally, t3 is when the defrost frequency of the compressor is the minimum preset defrost frequency P m When t3 is set, the time required for the room to start defrosting and the temperature to drop by 3 degrees is recorded. Specifically, the value of t3 can be 180s. i When the air is in the third preset thickness interval (0, δ0), the defrosting frequency and single defrosting time of the compressor are adjusted more accurately according to the frost thickness of the outdoor unit.

[0053] Optionally, P1 = 2*β*CC / S. Where β is a dimensionless coefficient without actual numerical value. t1 = t3 + 10s. It is beneficial to i When the air is in the first preset thickness interval (δ0, δ1), the defrost frequency and single defrost duration of the compressor are adjusted more accurately according to the frost thickness of the outdoor unit.

[0054] Optionally, P2 = 2.5*β*CC / S. Where β is a dimensionless coefficient without actual numerical value. t2 = t3 + 15s. It is beneficial to i When in the second preset thickness interval (δ1, +∞), the defrost frequency and single defrost duration of the compressor are adjusted more accurately according to the frost thickness of the outdoor unit.

[0055] Optionally, the air conditioner adjusts the gear of the indoor electric heating according to the temperature difference of the indoor temperature drop during the defrost period, including: when the temperature difference of the indoor temperature drop during the defrost period is in the first preset temperature interval [T1, T2), the air conditioner adjusts the gear of the indoor electric heating to the first heating gear. When the temperature difference of the indoor temperature drop during the defrost period is in the second preset temperature interval [T2, T3), the air conditioner adjusts the gear of the indoor electric heating to the second heating gear. When the temperature difference of the indoor temperature drop during the defrost period is in the third preset temperature interval [T3, +∞), the air conditioner adjusts the gear of the indoor electric heating to the third heating gear. Among them, the first preset temperature interval is lower than the second preset temperature interval, the second preset temperature interval is lower than the third preset temperature interval, the first heating gear is lower than the second heating gear, and the second heating gear is lower than the third heating gear.

[0056] Specifically, the air conditioner adjusts the indoor electric heating gear to the first heating gear, including: the air conditioner controls the lower electric heating to turn on, and the upper electric heating and the middle electric heating to turn off. The air conditioner adjusts the indoor electric heating gear to the second heating gear, including: the air conditioner controls the lower electric heating and the middle electric heating to turn on, and the upper electric heating to turn off. The air conditioner adjusts the indoor electric heating gear to the second heating gear, including: the air conditioner controls the lower electric heating, the middle electric heating and the upper electric heating to turn on.

[0057] Specifically, the value of T1 may be 3° C., the value of T2 may be 5° C., and the value of T3 may be 7° C. The values ​​of T1, T2, and T3 may be adjusted and set according to the properties of the air conditioner, and are not listed here one by one.

[0058] In this way, the greater the temperature difference of the indoor temperature drop during the defrosting period, the greater the gear of the indoor electric heating. This is conducive to more accurately adjusting the gear of the indoor electric heating according to the temperature difference of the indoor temperature drop during the defrosting period. Accurately controlling the defrosting process without blindly increasing or shortening the defrosting time is conducive to reducing room temperature fluctuations when the air conditioner outdoor unit is defrosted, saving energy and electricity, and avoiding malfunctions caused by ice formation in the outdoor unit.

This is conducive to more accurate control of the defrosting process, without blindly increasing or shortening the defrosting time, and is conducive to reducing room temperature fluctuations when the outdoor unit of the air conditioner is defrosted, saving energy and electricity, and avoiding failures caused by icing of the outdoor unit.

[0072] Optionally, the air conditioner adjusts the ratio of the compressor current to the total current protective shutdown current according to the increase rate of the compressor defrost frequency, including: the air conditioner adjusts the compressor current to the total current protective shutdown current according to the increase rate of the compressor defrost frequency P i Specifically, the air conditioner adjusts the ratio of the compressor current to the total current protective shutdown current according to the increase rate of the compressor. i The increase rate of the compressor current is positively correlated to the proportion of the total current protective shutdown current, including: P i The greater the rate of increase, the greater the ratio of the compressor current to the total current protective shutdown current A+△A or B+△B. Among them, △A and △B are the increase values ​​of the ratio of the compressor current to the total current protective shutdown current, A+△A≤A max , B+△B≤B max , A max , B max is the maximum value of the compressor current as a percentage of the total current protective shutdown current.
