The application discloses an air duct structure of an air conditioner and an air outlet control method thereof. The air duct structure comprises a split indoor unit and an outdoor unit, the indoor unit and the outdoor unit are connected with each other through an air
pipe and a liquid
pipe, the indoor unit comprises
indoor air fans which are arranged below a side of a device to be cooled respectively, a
refrigeration circuit, a return air / new air outlet, a temperature sensor and an
electric control box. The
refrigeration circuit comprises a gas circuit connected with the air
pipe and a liquid circuit connected with the liquid pipe, and the
refrigeration circuit cools the
indoor air fans through an
evaporator. The return air / new air outlet switches the return air outlet or the new air outlet according to the air outlet temperature of the
indoor air fan. The temperature sensor detects the air outlet temperature and the ambient temperature at the air outlet of each indoor air fan respectively. The
electric control box controls the switching of the return air outlet and the new air outlet according to the detected air outlet temperature and ambient temperature, and adjusts the frequency of the air conditioner. The air outlet is arranged at the side and the bottom of different charging devices, the air outlet is accurately sent to the corresponding device, the air supply is more reasonable and uniform, and the temperature regulation efficiency of the air conditioner is improved.
