[0032] According to an embodiment of the present application, a method for controlling an air conditioner is provided.

[0033] Figure 1 FIG. 1 is a flow chart of a method for controlling an air conditioner according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0034] Step S101, when it is determined that the outdoor electric control panel of the air conditioner is in an overheated state, the exhaust temperature of the compressor is obtained.

[0035] Exemplarily, the overheating state of the outdoor electric control board can be monitored by monitoring the outdoor ambient temperature T and the compressor current DL, or by a temperature sensor on the electric control board. The present application obtains the exhaust temperature TP of the compressor when the outdoor electric control board is in an overheating state, so as to control the temperature of the outdoor electric control board of the air conditioner to be in a normal state.

[0036] Step S102, when the exhaust temperature is greater than the exhaust temperature threshold, lowering the target exhaust temperature of the compressor to reduce the heat generated by the outdoor electric control panel.

[0037] Specifically, Figure 2 As shown, the exhaust temperature threshold corresponding to the compressor exhaust temperature TP can be TP a, or TP b , …, TP n+5 Any one of them, respectively TP and TP a TP b , …, TP n+5 A comparison is made to obtain an exhaust temperature comparison result. When the exhaust temperature is greater than the exhaust temperature threshold, the target exhaust temperature of the compressor is reduced to reduce the heat generated by the outdoor electric control panel.

[0038] Step S103, when the exhaust temperature is less than or equal to the exhaust temperature threshold, the frequency of the compressor is reduced to reduce the heat generated by the outdoor electric control panel.

[0039] Specifically, Figure 2 As shown, the exhaust temperature threshold corresponding to the compressor exhaust temperature TP can be TP a , or TP b , …, TP n+5 Any one of them, respectively TP and TP a TP b , …, TP n+5 A comparison is made to obtain an exhaust temperature comparison result. When the exhaust temperature is less than or equal to the exhaust temperature threshold, the frequency of the compressor is reduced to reduce the heat generated by the outdoor electric control panel.

[0040] In some embodiments, when determining that the outdoor electrical control panel of the air conditioner is in an overheated state, before obtaining the exhaust temperature of the compressor, the method also includes: obtaining the outdoor ambient temperature and the current of the compressor; when the outdoor ambient temperature is greater than the outdoor ambient temperature threshold and the current is greater than the first current threshold, determining that the outdoor electrical control panel of the air conditioner is in an overheated state.

[0041] For example, Figure 2 As shown, the outdoor ambient temperature threshold corresponding to the outdoor ambient temperature T can be T0, T5, ..., T n+5 The first current threshold corresponding to the current DL of the air conditioner outdoor unit may be DL a1 , can also be DL b1 …、DL n1 ,DL (n+5)1 Any one of .

[0042] In some embodiments, Figure 2 As shown, when the outdoor ambient temperature is less than or equal to the outdoor ambient temperature threshold, or the outdoor ambient temperature is greater than the outdoor ambient temperature threshold and the current is less than or equal to the first current threshold, the air conditioner is controlled to operate according to the initial default cooling mode.

[0043] For example, during the time period t1min when the air conditioner is turned on, the outdoor ambient temperature threshold corresponding to the outdoor ambient temperature T may be T0, T5, ..., T n+5 If the outdoor ambient temperature T is less than or equal to T0, T5, ..., T n+5 When any one of the above is reached, the air conditioner is controlled to operate according to the initial default cooling mode. The present application determines an effective air conditioning operation mechanism by establishing a comparison mechanism between the outdoor ambient temperature and the outdoor ambient temperature threshold, thereby ensuring that the outdoor electric control panel can operate normally when the temperature of the air conditioner outdoor unit is too high.

[0044] For example, the first current threshold corresponding to the current DL of the air conditioner outdoor unit may be DL a1 , can also be DL b1 …、DL n1 ,DL (n+5)1 If any one of the above is detected, the air conditioner outdoor unit current DL is less than or equal to DL a1 ,DL b1 …、DL n1 ,DL (n+5)1 Any one of them controls the operation of the air conditioner according to the initial default cooling mode. The present application determines an effective air conditioning operation mechanism by establishing a comparison mechanism between the current of the air conditioner outdoor unit and the first current threshold, thereby ensuring that the outdoor electric control panel of the air conditioner can operate normally when the temperature of the air conditioner outdoor unit is too high.

[0045] In some embodiments, Figure 2 As shown, when the target exhaust temperature of the compressor is lowered, the method further includes: increasing the opening degree of the throttling component.

[0046] The throttling component may be the expansion valve opening, for example, increasing the expansion valve opening Lr to Lr a / Lr b / …… / Lr n / Lr n+5 The present application uses an outdoor unit with an electronic expansion valve to control the opening of the outdoor unit to adjust the target exhaust temperature, thereby reducing the power without significantly reducing the cooling effect, and can be used to alleviate the problem of excessive heat in the outdoor electric control panel.

[0047] In some embodiments, after lowering the target exhaust temperature of the compressor and increasing the opening of the throttling component, the method further includes: after a delay of a first preset time, re-determining whether the outdoor electric control panel of the air conditioner is in an overheated state.

[0048] For example, Figure 2 As shown, the compressor exhaust temperature TP can be reduced by 1 degree, and the target exhaust temperature TP can be obtained respectively. a -1.TP b-1, ..., TP n+5 -1, increase the expansion valve opening Lr to Lr a / Lr b / …… / Lr n / Lr n+5 After that, the air conditioner is operated for t2min, and the step of determining whether the outdoor electric control panel of the air conditioner is in an overheated state is re-entered. For example, Figure 2 As shown, after the air conditioner outdoor unit runs for t2min, it is detected whether the outdoor ambient temperature T is greater than the corresponding outdoor ambient temperature thresholds T0, T5, ..., T n+5 step.

[0049] In some embodiments, when reducing the frequency of the compressor, the method further includes: increasing the rotation speed of the outdoor fan.

[0050] For example, Figure 2 As shown, increase the speed of the outdoor fan Pr to Pr a Or other corresponding speed Pr b / …… / Pr n / Pr n+5 , reduce the compressor frequency Fr of the air conditioner to Fr a1 Or other corresponding frequency Fr b1 / …… / Fr n1 / Fr (n+5)1 The present application can further prevent the outdoor electric control panel from being in an excessively high heat state by increasing the speed of the air conditioner or reducing the frequency.

[0051] In some embodiments, after reducing the frequency of the compressor and increasing the speed of the outdoor fan, the method also includes: re-acquiring the current of the compressor after a delay of a second preset time; when the current is less than a second current threshold, keeping the frequency of the compressor unchanged, restoring the speed of the outdoor fan, and re-determining whether the outdoor electrical control panel of the air conditioner is in an overheating state; wherein the second current threshold is less than the first current threshold; when the current is greater than or equal to the second current threshold, continuing to reduce the frequency of the compressor, and after a delay of a third preset time, returning to the step of re-acquiring the current of the compressor.

[0052] For example, the speed Pr of the outdoor fan is increased to Pr a Or other corresponding speed Pr b / …… / Pr n / Pr n+5 , reduce the compressor frequency Fr of the air conditioner to Fr a1 Or other corresponding frequency Fr b1 / …… / Fr n1 / Fr (n+5)1The outdoor unit of the air conditioner reacquires the current of the compressor after the time period t3min, and compares the current DL of the compressor with the corresponding second current threshold DL a2 , can also be DL b2 …、DL n2 ,DL (n+5)2 Any one of them is compared respectively to obtain a current comparison result. When the current is less than the second current threshold, the frequency of the compressor is kept unchanged and the speed of the outdoor fan is restored. After the air conditioner runs for a period of t4min, it is re-determined whether the outdoor electric control board of the air conditioner is in an overheated state. That is, the present application can achieve heat control of the outdoor electric control board by controlling and adjusting the speed and frequency of the air conditioner without adjusting the target exhaust temperature multiple times.

[0053] For another example, when the current is greater than or equal to the second current threshold, the frequency of the compressor continues to be reduced, and after a delay of t5min, the process returns to the step of reacquiring the current of the compressor.

[0054] In some embodiments, the first current threshold, the exhaust temperature threshold, the lowered target exhaust temperature, and the increased opening of the throttling component are in a corresponding relationship with the outdoor ambient temperature threshold.

[0055] For example, Figure 2 As shown, when the outdoor ambient temperature is greater than the outdoor ambient temperature threshold T0, if the current is greater than the first current threshold DL a1 , then the target exhaust temperature is greater than the exhaust temperature threshold TP a , the corresponding target exhaust temperature is reduced to TP a -1, the throttle valve opening increases to Lr a When the outdoor ambient temperature is greater than the outdoor ambient temperature threshold value T5, the corresponding relationship is as follows: Figure 2 The same is true for the above, and no further details are given here.

[0056] In some embodiments, the reduced frequency of the compressor, the increased speed of the outdoor fan, and the second current threshold are in a corresponding relationship with the outdoor ambient temperature threshold.

[0057] For example, when the outdoor ambient temperature T is greater than the outdoor ambient temperature threshold T0, if the current is greater than the first current threshold DL a1 , then the target exhaust temperature is less than or equal to the exhaust temperature threshold TP a , reduce the frequency to Fr a1 After that, increase the speed to Pr a , monitor whether the second current threshold is less than DL a2 , where the reduced compressor frequency, the increased outdoor fan speed and the second current threshold correspond to the outdoor ambient temperature threshold as shown in Figure 2 The same is true for the above, and no further details are given here.

[0058] It should be noted that in the above embodiments of the present application, DL a1 >DL a2 , DL b1 >DL b2 , DL n1 >DL n2 , DL (n+5)1 >DL (n+5)2 ; and, Fr a1 >Fr a2 ,Fr b1 >Fr b2 ,Fr n1 >Fr n2 ,Fr (n+5)1 >Fr (n+5)2 .

[0059] In summary, the control method of the air conditioner provided in the embodiment of the present application obtains the exhaust temperature of the compressor when it is determined that the outdoor electric control board of the air conditioner is in an overheated state; when the exhaust temperature is greater than the exhaust temperature threshold, the target exhaust temperature of the compressor is reduced to reduce the heat generated by the outdoor electric control board; when the exhaust temperature is less than or equal to the exhaust temperature threshold, the frequency of the compressor is reduced to reduce the heat generated by the outdoor electric control board. Through this application, the problem of the air conditioner outdoor electric control board temperature being too high in the related art, resulting in the air conditioner being unable to operate normally, is solved, and by controlling the exhaust temperature and compressor frequency of the compressor, the temperature of the air conditioner outdoor electric control board temperature is effectively reduced, achieving the effect of normal operation of the air conditioner.
