Air conditioner and control method thereof

The invention provides an air conditioner and a control method thereof.The control method of the air conditioner comprises the steps that the surface temperature Tr of an evaporator of the air conditioner is obtained; if the surface temperature Tr meets a first anti-freezing mode starting condition, starting a first anti-freezing mode; and starting a second anti-freezing mode after the first anti-freezing mode achieves an adjustment target. The problem of temperature fluctuation caused when the air conditioner operates a freezing protection mechanism is relieved. 本发明提供了一种空调及其控制方法，空调的控制方法，包括获取所述空调的蒸发器表面温度Tr；若所述表面温度Tr满足第一防冻模式开启条件，开启所述第一防冻模式；所述第一防冻结模式达成调节目标后，启动第二防冻模式。本发明缓解了空调在运行冻结保护机制时所引起的温度波动问题。
