Abstract: A method of judging lack-of-freon in an air conditioner and an air conditioner control method. The control method includes: acquiring outflow air temperatures at the first air outlet and the second air outlet, and calculating a temperature difference; comparing the temperature difference with a preset temperature difference threshold; and adjusting an opening degree of the expansion valve accordingly. In the method, the opening degree of the expansion valve can be automatically adjusted according to a result of temperature comparison to compensate for the flow rate of freon, so as to improve the cooling or heating efficiency of the air conditioning system and realize the adaptive adjustment of the air conditioner, thereby ensuring the cooling or heating efficiency of the system even if the system lacks freon to a slight extent and effectively reducing energy consumption. The judging method has a higher accuracy of judging result, and is easier to implement.
