The invention discloses a control method and device of a unit and an air conditioner. The control method of the unit comprises the steps that a first change rate of an inner tube temperature in the unit and a first change speed of the rate are obtained; the first change rate is compared with a preset change rate, and the first change speed of the rate is compared with a preset change speed; and ifthe first change rate is larger than or equal to the preset change rate and the first change speed of the rate is larger than or equal to the preset change speed, the rotating speed of a draught fanof the unit is adjusted. According to the control method and device of the unit and the air conditioner, the technical problem that when an air conditioner unit operates in a related technology, overload protection of a compressor is prone to occurring and causes the damage on the compressor is solved. 本发明公开了一种机组的控制方法及装置、空调器。其中，该方法包括：获取机组中内管温度的第一变化速率和速率的第一变化速度；将第一变化速率和预设变化速率进行比较，并将速率的第一变化速度和预设变化速度进行比较；若第一变化速率大于等于预设变化速率且速率的
