In the present embodiment, a controller is provided in the air conditioner, and the main execution body of the defrosting control method provided in the present embodiment is the controller in the air conditioner. A temperature sensor is arranged on the coil pipe of the outdoor heat exchanger in the air conditioner. When the air conditioner runs in a heating mode, the temperature sensor on the outdoor heat exchanger coil collects the temperature value of the outdoor heat exchanger coil in real time, and when the defrosting condition is met according to the temperature value of the outdoor heat exchanger coil, the controller is controlled to enter a defrosting mode. Wherein the defrosting conditions include: the temperature value of the outdoor heat exchanger coil is smaller than the preset temperature value, and the time length of the temperature value of the outdoor heat exchanger coil smaller than the preset temperature value is longer than the preset time length. The preset temperature value and the preset time length can be set according to actual needs, and specific numerical values of the preset temperature value and the preset time length are not specifically limited in this embodiment. The defrosting mode is to switch the air conditioner from the heating mode to the cooling mode by controlling the four-way valve to work, and to control the indoor fan in the air conditioner to stop working.
Specifically, when the air conditioner is in a defrosting mode, the existing reverse cycle defrosting mode can be adopted for defrosting, and during the defrosting, the indoor fan in the air conditioner is controlled to stop running, so that the heat exchange between the indoor heat exchanger and the indoor air in the air conditioner is reduced, and the heat is used for defrosting of the outdoor heat exchanger in the air conditioner. If the above method is adopted all the time, the defrosting efficiency of the air conditioner will be affected (i.e. the technical problem in the prior art). Therefore, in the defrosting process of the air conditioner adopting the method in the embodiment, the first temperature value of the coil pipe of the outdoor heat exchanger is acquired by the temperature sensor on the coil pipe of the outdoor heat exchanger in real time, and whether the indoor fan in the air conditioner needs to be started or not is determined by the first temperature value, so that the heat of the indoor heat exchanger is effectively utilized, and the defrosting efficiency of the air conditioner is improved.

s201: under the condition that the air conditioner is in a defrosting mode, a first temperature value of an outdoor heat exchanger coil pipe in the air conditioner, a second temperature value of a space where the air conditioner is located and a third temperature value of the air conditioner are obtained.
In this embodiment, in the step S201, under the condition that the air conditioner is in the defrosting mode, the obtaining of the first temperature value of the outdoor heat exchanger coil in the air conditioner is consistent with the step S101, which is not described herein again, and reference may be made to the above description specifically. And the third temperature value of the air conditioner is used for representing the temperature set value of the air conditioner. The temperature setting value may be set by a user through a remote controller, and of course, the user may also set the temperature value through an application installed in the terminal.
Specifically, when the air conditioner is in a defrosting mode, in the process of controlling the indoor fan by using the first temperature value, the indoor fan is further judged by the acquired second temperature value of the space where the air conditioner is located and the acquired third temperature value of the air conditioner, so that the comfort of users in the space is improved. More specifically, a temperature sensor is arranged in the space where the air conditioner is located, and the temperature sensor acquires a second temperature value of the space where the air conditioner is located in real time.

The preset temperature interval can be set according to actual needs, and the specific interval range of the preset temperature interval in the embodiment is not specifically limited. For example, the predetermined temperature range may be [ -1 ℃,1 ℃ ]. It should be noted that, when the preset temperature interval is set, it is to be ensured that the time between the defrosting determination and the indoor fan operation determination according to the first temperature value is not too short, and if the time is too short, the temperature value in the space and the set value of the air conditioner generate a large temperature difference, so that the comfort of the user in the space is affected.
S203: and when the first temperature value meets a first preset condition, determining the control strategy as a first control strategy.
In this embodiment, in the process of controlling the air conditioner to defrost, when it is determined that the first temperature value is within the preset temperature interval, the operation of the indoor fan in the air conditioner needs to be controlled (i.e., the first control strategy) is characterized.

It should be noted that, in the process of controlling the air conditioner to defrost (i.e., in the process of stopping the operation of the indoor fan), the control strategy is determined to be the first control strategy only when the first temperature value satisfies the first preset condition, and the fourth control strategy is determined as long as the first temperature value does not satisfy the first preset condition, and the fourth control strategy is to control the indoor fan to maintain the original control (i.e., control the indoor fan to continue to stop the operation).
S206: and when the control strategy is the fourth control strategy, controlling the indoor fan to continuously stop running.
In this embodiment, when the control strategy is the fourth control strategy, it is not necessary to control the operation of the indoor fan, and it is only necessary to control the indoor fan to maintain the original control.

In this embodiment, when first temperature value satisfies first predetermined condition, control indoor fan operation this moment, indoor heat exchanger coil pipe carries out the heat transfer in the air conditioner with higher speed in the operation of indoor fan, when indoor heat exchanger coil pipe carries out the heat transfer, can influence the temperature value of the space that the air conditioner is located, when the temperature value of space is low excessively, can influence the user's in the space travelling comfort, so, adopt the in-process of indoor fan operation in order to improve the defrosting efficiency of air conditioner defrosting, in order to guarantee user's travelling comfort in the space, second temperature value and the third temperature value of air conditioner through the space that the air conditioner that gathers is located, decide whether to continue to control indoor fan operation, still control indoor fan out of service. Specifically, the target difference between the second temperature value and the third temperature value is an absolute value of a difference between the second temperature value and the third temperature value.
S208: and judging whether the target difference value is smaller than or equal to a preset threshold value.
In this embodiment, the preset threshold may be set according to actual needs, and a specific numerical value of the preset threshold is not specifically limited in this embodiment. For example, any value between 0 ℃ and 2 ℃ can be selected as the preset threshold. Wherein, the condition that whether the target difference is less than or equal to the preset threshold is the condition for deciding the running state of the indoor fan, and the running state of the indoor fan comprises: the indoor fan operates and the indoor fan stops operating.
S209: and when the target difference value is smaller than or equal to the preset threshold value, determining that the control strategy is switched from the first control strategy to the second control strategy.
In this embodiment, when it is determined that the target difference is smaller than or equal to the preset threshold, it is characterized that the temperature in the space at this time can ensure the comfort of the user in the space where the air conditioner is located, the determined control strategy is the second control strategy, and the second control strategy is to control the indoor fan to continue to operate, that is, to continue to control the indoor fan to operate, so as to accelerate the heat exchange of the indoor heat exchanger coil in the air conditioner, thereby improving the defrosting efficiency of the air conditioner.
S210: and when the control strategy is the second control strategy, controlling the indoor fan to continue to operate.
In this embodiment, when the indoor fan is controlled to continue to operate, the indoor fan may be controlled to operate in a manner that the control strategy is the first control strategy, for example, the indoor fan is controlled to continue to operate at the lowest rotation speed value, or the upper air outlet of the indoor unit is controlled to be opened while the indoor fan is controlled to continue to operate.
