Cold air prevention control method of air conditioner and air conditioner

The invention provides an air conditioner and a windproof control method of the air conditioner, and the method comprises the following steps: when defrosting of the air conditioner is finished or heating is started, the indoor environment temperature T1, the indoor coil pipe temperature T2 and the user remote control set temperature Tst are detected in real time, and when T2 < = T1 and T2 < = Tst are met, the air conditioner enters a cold air prevention mode; t2 and the rising speed delta T2/delta t of the indoor coil pipe temperature are obtained in real time, if T2 is larger than or equal to TS1, obtaining is carried out, delta T2/delta t is larger than or equal to K1, and an indoor fan is controlled to be started and run at the first running speed; if T2 is larger than or equal to TS2 and delta T2/delta t is larger than or equal to K2, the indoor fan is controlled to be started and run at the second running speed; wherein K1 is smaller than K2 and larger than 0, and TS1 is smaller than TS2; and whether T2
