Abstract
The present application provides an air duct machine with switchable air-out directions and a control method thereof, and an air-conditioning apparatus. The air duct machine with switchable air-out directions comprises: a housing, a first fan (3), a second fan (4) and a control mechanism, wherein the first fan (3) and the second fan (4) are both mounted in the housing, the housing has a first vent (1) at a side corresponding to the first fan (3) and a second vent (2) at a side corresponding to the second fan (4), and a communicating air channel is formed between the first vent (1) and the second vent (2); the control mechanism is used for linkage control of the rotation of two fans, and when one fan serves as an air supply fan, the other fan is controlled as a regulating fan to rotate in a direction opposite to a direction in which air is supplied to a corresponding vent, and reverse rotation of the regulating fan reduces obstruction to return air, optimizes a flow field of return air, enlarges the area of return air, increases the air output amount, and effectively lowers the noise.
