Document Type and Number:
WIPO Patent Application WO/2019/208171
Kind Code:
A1
Abstract:
Provided is an indoor unit for an air conditioner with which it is possible to increase the size of a propeller fan and improve air flow while preventing any condensation water from dripping from a blowout opening. An indoor unit (1) for an air conditioner, provided with: a propeller fan (9) surrounded by a heat exchanger (8), the propeller fan (9) causing air (K) suctioned from a sideward suction opening (6) to be blown out from a downward blowout opening (7); and a drain pan (11) provided below the heat exchanger (8), the drain pan receiving condensation water produced by the heat exchanger (8). A surface treatment is performed on the heat exchanger (8) so that the water contact angle with respect to the surface of the heat exchanger (8) is equal to or less than 50°. The heat exchanger (8) and the propeller fan (9) are disposed so that the relational formula 0.05 ≤ L/D < 0.19 is satisfied, where L is the distance between the heat exchanger (8) and the propeller fan (9) in the horizontal direction, and D is the diameter of the propeller fan (9).
