Provided are a defrosting control device, an air conditioner and a defrosting control method therefor. The device includes an airbag device, wherein the airbag device includes a mounting support (), an airbag () and an inflation mechanism. When an air conditioner to be controlled enters a defrosting mode, the inflation mechanism inflates the airbag () such that same forms an airbag layer to isolate an outdoor heat exchanger of the air conditioner to be controlled from flowing air outside the outdoor heat exchanger. The defrosting control device can achieve the beneficial effects of a small defrosting heat loss, a good defrosting effect and a good user experience.
