Document Type and Number:
WIPO Patent Application WO/2020/012525
Kind Code:
A1
Abstract:
This indoor unit for air conditioners has: a casing (4) in which an intake port (2) and a blow-out port (3) are formed; a load-side heat exchanger (6) in which air suctioned from an air-conditioning target space exchanges heat with a refrigerant; a cross-flow fan (7) that supplies the load-side heat exchanger with the air suctioned from the air-conditioning target space; and a motor (32). The cross-flow fan has: a shaft connected to the motor; a first impeller (10) that suctions air from the air-conditioning target space through the intake port when the shaft rotates in the forward direction; a second impeller (20) that suctions air from the air-conditioning target space through the blow-out port when the shaft rotates in the reverse direction; a first clutch (12) that transmits the torque of the forward-rotating shaft to the first impeller and idly rotates when the shaft rotates in the reverse direction; and a second clutch (22) that transmits the torque of the reverse-rotating shaft to the second impeller and idly rotates when the shaft rotates in the forward direction.
