Referring to fig. 2, an embodiment of the present disclosure provides a method for controlling an air conditioner, which is applied to the air conditioner. The air conditioner includes an indoor unit and an outdoor unit. Wherein, the outdoor unit comprises an outdoor coil pipe. The indoor unit comprises an indoor coil pipe; the air conditioner is provided with a plurality of branches, and each branch is used for refrigerant circulation. The method comprises the following steps:
step S201, under the condition that the temperature of the first coil of the outdoor coil is not changed, the air conditioner sequentially controls the shunts to be independently opened, and respectively obtains the temperatures of the second coils corresponding to the shunts. Wherein the second coil temperature is the coil temperature of the indoor coil under the condition that each shunt is independently opened.

In step S203, the air conditioner determines a preset first refrigerant leakage state as an indoor unit refrigerant leakage condition.
And step S204, the air conditioner determines the preset second refrigerant leakage state as the indoor unit refrigerant leakage condition.
By adopting the method for controlling the air conditioner provided by the embodiment of the disclosure, the temperature of the second coil pipe when each shunt is independently opened is obtained under the condition that the temperature of the first coil pipe of the outdoor coil pipe is not changed. And determining the indoor unit refrigerant leakage condition according to the equal relation among the temperatures of the second coil pipes.

The time for maintenance personnel to locate the position where the refrigerant is leaked is reduced, and the maintenance efficiency is improved.
Optionally, the air conditioner is equipped with a compressor. The refrigerant leakage condition of the outdoor unit is detected by the following method: the current frequency of the compressor is obtained. A plurality of target compressor frequencies are determined based on the current frequency. And sequentially setting the frequency of the compressor as the target compressor frequency, and respectively acquiring the temperature of the third coil corresponding to each target compressor frequency. The third coil temperature is a coil temperature of the indoor coil when the frequency of the compressor is the target compressor frequency. And acquiring the refrigerant leakage condition of the outdoor unit according to the temperature of each third coil pipe. Therefore, the outdoor unit refrigerant leakage condition is obtained according to the third coil pipe temperatures by obtaining the third coil pipe temperatures of the indoor coil pipes of the compressors under the conditions that the compressors are at different target compressor frequencies. The detection of the leakage condition of the refrigerant of the outdoor unit is realized.
Further, control each reposition of redundant personnel all to be in the open mode, include: and controlling the throttle valves corresponding to the branches to be in an opening state.
Further, before obtaining the current frequency of the compressor, the method further includes: and controlling each shunt to be in an opening state. And controlling the electromagnetic expansion valve to be in a power-off state.
In some embodiments, after controlling each split flow to be in an open state and controlling the electromagnetic expansion valve to be in a power-off state, the opening and closing angle of the electromagnetic expansion valve can be kept unchanged. At this time, the first coil temperature of the outdoor coil is varied with a variation in the frequency of the compressor. The refrigerant flow is controlled by controlling the valve opening of each branched throttling valve, so that the temperature of the first coil pipe of the outdoor coil pipe can be controlled to be unchanged. In the case where the frequency of the compressor is increased, the valve opening degree of the throttle valve for each split flow is decreased. When the frequency of the compressor is decreased, the valve opening of the throttle valve for each split flow is increased. In this way, the temperature of the first coil can be kept constant.
Optionally, the target compressor frequency comprises a first target frequency, a second target frequency, and a third target frequency; determining a plurality of target compressor frequencies from the current frequency, including: and acquiring the current frequency of the compressor and a preset frequency deviation value. The current frequency is determined as a first target frequency.

In this way, the first target frequency, the second target frequency and the third target frequency are obtained according to the current frequency and the preset frequency deviation value. So as to obtain a third coil temperature of the indoor coil with the compressor at a different target compressor frequency.

And determining a difference value between the current frequency and the frequency deviation value as a second target frequency.
Optionally, obtaining the refrigerant leakage condition of the outdoor unit according to the temperature of each third coil pipe, includes: a first difference between the sixth coil temperature and the fourth coil temperature is obtained. A second difference between the sixth coil temperature and the fifth coil temperature is obtained. The sixth coil temperature is a third coil temperature corresponding to the first target frequency; the fourth coil temperature is a third coil temperature corresponding to the second target frequency. And the fifth coil temperature is a third coil temperature corresponding to the third target frequency. And determining the refrigerant leakage condition of the outdoor unit according to the first difference value and the second difference value. In this way, the outdoor unit refrigerant leakage condition can be determined according to a first difference between the sixth coil temperature and the fourth coil temperature and a second difference between the sixth coil temperature and the fifth coil temperature. So as to determine the refrigerant leakage condition of the air conditioner according to the refrigerant leakage condition of the outdoor unit.

And/or determining the preset second refrigerant leakage state as the refrigerant leakage condition of the outdoor unit under the condition that the absolute value of the first difference is smaller than or equal to the absolute value of the second difference.
In some embodiments, the second target frequency is greater than the first target frequency. The first target frequency is greater than the third target frequency. When the frequency of the compressor is changed from the first target frequency to the second target frequency, the compressor is in an up-conversion state. The pressure provided by the compressor is high, and the pressure output to the indoor unit by the compressor is high. The frequency of the compressor has a large effect on the coil temperature of the indoor coil. When the frequency of the compressor is changed from the second target frequency to the third target frequency, the compressor is in a down-conversion state. When the pressure supplied from the compressor is low, the pressure output from the compressor to the indoor unit is low. Therefore, the frequency of the compressor has little effect on the coil temperature of the indoor coil. Therefore, if the absolute value of the first difference is greater than the absolute value of the second difference, the refrigerant of the outdoor unit does not leak. And if the absolute value of the first difference is smaller than or equal to the absolute value of the second difference, the refrigerant of the outdoor unit leaks.

In step S306, the air conditioner determines whether the absolute value of the first difference is greater than the absolute value of the second difference. If yes, go to step S307; if not, go to step S308.
In step S307, the air conditioner determines the preset first refrigerant leakage state as an outdoor unit refrigerant leakage condition.
