The apparatus of claim 5 or 6, wherein the air conditioner has an upper air outlet and a lower air outlet; an outdoor throttling element is arranged between the outdoor heat exchanger and the indoor heat exchanger of the air conditioner, the indoor heat exchanger of the air conditioner is provided with an indoor throttling element, and the control unit is further used for:
And controlling the opening degree of an indoor throttling element, the opening degree of an outdoor throttling element, the rotating speed of an indoor fan and/or the rotating speed of an outdoor fan of the air conditioner according to the determined running mode of the air conditioner.
8. The apparatus according to claim 7, wherein the control unit controls an indoor throttling element opening, an outdoor throttling element opening, an indoor fan speed and/or an outdoor fan speed of the air conditioner according to the determined operation mode of the air conditioner, comprising:
if the operation mode of the air conditioner is a refrigeration mode, controlling the indoor throttling element to be opened to the maximum opening, and controlling the opening of the outdoor throttling element, the rotating speed of the indoor fan and/or the rotating speed of the outdoor fan according to the refrigeration requirement of the air conditioner;
if the operation mode of the air conditioner is a heating dehumidification mode or a constant temperature dehumidification mode, controlling the outdoor throttling element to be opened to a maximum opening degree, and controlling the outdoor fan to operate according to a preset minimum rotating speed or to be closed for a preset time and/or controlling the opening degree of the indoor throttling element according to the dehumidification requirement of the air conditioner, wherein the opening degree of the indoor throttling element is smaller as the dehumidification requirement of the air conditioner is larger; the rotating speed of the indoor fan when the air conditioner operates in a temperature rising and dehumidification mode is larger than that of the indoor fan when the air conditioner operates in a constant temperature dehumidification mode;
If the operation mode of the air conditioner is a cooling and dehumidifying mode, controlling the indoor throttling element to be opened to the maximum opening, and controlling the opening of the outdoor throttling element and/or the rotating speed of the outdoor fan according to the refrigerating requirement of the air conditioner, or controlling the outdoor fan to operate according to the preset minimum rotating speed or to be closed for a preset time and/or controlling the opening of the indoor throttling element according to the dehumidifying requirement of the air conditioner, wherein the opening of the indoor throttling element is smaller as the dehumidifying requirement of the air conditioner is larger.
