Air duct machine with switchable air-out directions and control method thereof and air-conditioning apparatus

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 (), a second fan () and a control mechanism, wherein the first fan () and the second fan () are both mounted in the housing, the housing has a first vent () at a side corresponding to the first fan () and a second vent () at a side corresponding to the second fan (), and a communicating air channel is formed between the first vent () and the second vent (); 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.
