Referring to fig. 1, a flowchart of a defrosting control method for an air conditioner according to a first embodiment of the present invention is shown. The defrosting control method of the air conditioner comprises the following steps:
firstly, controlling an air conditioner to enter a defrosting mode, and acquiring the defrosting time t of the air conditioner.
The defrosting time of the air conditioner can be acquired through a preset timer. For example, when the air conditioner enters a defrosting mode, a timer is started to time; and when the air conditioner exits the defrosting mode, stopping the timer for timing.
Secondly, judging whether the defrosting time t of the air conditioner is less than the longest defrosting time t of the air conditioner under the low-temperature working condition 0 (ii) a If T is less than T0, then according to the outdoor machine chassis temperature T d Judging whether the air conditioner exits the defrosting mode or not; and if t is more than or equal to t0, controlling the air conditioner to exit the defrosting mode. Specifically, the longest defrosting time t 0 Is 8-16min. Preferably, the maximum defrosting time t 0 Is 12min.
When the air conditioner enters a defrosting mode, the air conditioner changes the operation from indoor heating to outdoor heating. At the moment, the air conditioner external unit is an evaporator, and the surface temperature of the evaporator is increased to melt frost on the external coil pipe; the indoor unit of the air conditioner is changed into a condenser to perform indoor refrigeration operation. In order to ensure the normal heating operation of the indoor unit of the air conditioner, the air conditioner is not allowed to be in a defrosting mode for a long time, so the longest defrosting time t of the air conditioner is set 0 。
In one embodiment, if the defrosting time T of the air conditioner is less than 12min, the temperature T of the outdoor unit chassis of the outdoor unit of the air conditioner is continuously acquired d According to the outdoor unit chassis temperature T of the outdoor unit d And judging whether the ice on the chassis is completely melted or not, and further judging whether the air conditioner exits the defrosting mode or not.
If the defrosting time t of the air conditioner is more than or equal to 12min, the air conditioner is directly controlled to exit the defrosting mode without the need of the subsequent step of acquiring the temperature of the outdoor unit coil, so that the effects of saving operation resources and reducing energy consumption are achieved.
Further, the temperature T is determined according to the chassis temperature of the outdoor unit d Judging whether the air conditioner exits the defrosting mode comprises the following steps: obtaining outdoor unit coil temperature T p (ii) a Judging the temperature T of the coil pipe of the outdoor unit p And a first predetermined temperature T 1 The magnitude relationship of (1); if T is p ≥T 1 According to the outdoor ambient temperature T w Temperature T of outdoor unit chassis d Judging whether the air conditioner exits the defrosting mode or not by the difference value; if T p ＜T 1 Controlling the air conditioner to operate at the current defrosting frequency for a first preset time period t 1 And then according to the defrosting time T of the air conditioner and the outdoor unit coil temperature T p And judging whether the air conditioner exits the defrosting mode or not.

Preferably, the first preset temperature T 1 Is 10 ℃, the first preset time t 1 Is 1min.
In one embodiment, if the outdoor unit coil temperature T p More than or equal to 10 ℃, the temperature of the external coil pipe is high enough, namely, the frosting at the external coil pipe is melted completely, and then the temperature T is determined according to the outdoor environment w Temperature T of outdoor unit chassis d And judging whether the ice on the chassis is completely melted or not by the difference value between the two, and further judging whether the air conditioner exits the defrosting mode or not.
If T is p If the temperature is less than 10 ℃, the temperature of the outer coil is not high enough, namely the frosting on the surface of the outer coil is not melted completely, the air conditioner is controlled to continuously run for 1min at the current defrosting frequency, and the recycling execution is carried out according to the defrosting time T of the air conditioner and the temperature T of the coil of the outdoor unit p And judging whether the air conditioner exits the defrosting mode or not.
Further, the temperature T is based on the outdoor environment w Temperature T of outdoor unit chassis d The determining whether the air conditioner exits the defrosting mode by the difference value includes: obtaining outdoor ambient temperature T w Temperature T of outdoor unit chassis d (ii) a Determine outdoor ambient temperature T w And outdoor unit chassis temperature T d The difference between and the second preset temperature T 2 The magnitude relationship of (1); if T w -T d ≤T 2 Controlling the air conditioner to exit the defrosting mode; if T is w -T d ＞T 2 Controlling the air conditioner to increase the defrosting frequency and operate at the increased defrosting frequency for a second preset time period t 2 And then according to the defrosting time t of the air conditioner and the outdoor unit coil temperatureDegree T p And controlling the air conditioner to defrost. Wherein the second preset temperature T 2 Is 2-8 ℃, and the first preset time length t 1 The value range is 1-3min. Preferably, the second preset temperature T 2 At 5 ℃, the defrosting frequency is increased by 5HZ, and the second preset time period t 2 Is 2min.
In one embodiment, if T w -T d And if the temperature is less than or equal to 5 ℃, the temperature difference between the outdoor unit chassis temperature and the outdoor environment temperature is small enough, namely the ice on the chassis is melted completely, and the air conditioner is controlled to exit the defrosting mode.
If T w -T d If the temperature is higher than 5 ℃, the temperature difference between the outdoor unit chassis temperature and the outdoor environment temperature is larger, namely, the chassis still has ice which is not melted completely, and further defrosting operation is still needed. Therefore, the defrosting frequency of the air conditioner is controlled to be increased by 5HZ, the air conditioner is operated for 2min at the increased defrosting frequency, and the step of controlling the air conditioner to defrost according to the defrosting time t of the air conditioner and the outdoor unit coil temperature Tp is executed in a recycling mode.
